AB  - The rapid escalation of plastic waste accumulation presents a significant threat of the modern world, demanding an immediate solution. Over the last years, utilization of the enzymatic machinery of various microorganisms has emerged as an environmentally friendly asset in tackling this pressing global challenge. Thus, various hydrolases have been demonstrated to effectively degrade polyesters. Plastic waste streams often consist of a variety of different polyesters, as impurities, mainly due to wrong disposal practices, rendering recycling process challenging. The elucidation of the selective degradation of polyesters by hydrolases could offer a proper solution to this problem, enhancing the recyclability performance. Towards this, our study focused on the investigation of four bacterial polyesterases, including DaPUase, IsPETase, PfPHOase, and Se1JFR, a novel PETase-like lipase. The enzymes, which were biochemically characterized and structurally analyzed, demonstrated degradation ability of synthetic plastics. While a consistent pattern of polyesters’ degradation was observed across all enzymes, Se1JFR stood out in the degradation of PBS, PLA, and polyether PU. Additionally, it exhibited comparable results to IsPETase, a benchmark mesophilic PETase, in the degradation of PCL and semi-crystalline PET. Our results point out the wide substrate spectrum of bacterial hydrolases and underscore the significant potential of PETase-like enzymes in polyesters degradation.

AB  - Pseudomonas aeruginosa is a Gram-negative
pathogen responsible for frequent hospital-acquired
infections of the bloodstream, the respiratory
tract, and the urinary tract. Quorum
quenching enzymes are recognized as an alternative
antivirulence approach targeting pathogenic
bacteria. The efficacy of YtnP lactonase in
reducing the virulence of P. aeruginosa MMA83
in vivo using Caenorhabditis elegans as a model
system was investigated. The recombinant YtnP
lactonase exhibits no cytotoxicity, demonstrated
by its lack of harmful effects on both the
immortalized human HaCaT cell line and two
strains of C. elegans (AU37 and N2 wild-type). In
a toxin-mediated killing liquid assay, the survival
rates of C. elegans AU37 mutant and N2 wildtype
strains infected with the clinical isolate P.
aeruginosa MMA83 significantly increased when
pre-treated with YtnP lactonase, compared to
untreated controls. Considering that virulence
factors expression is regulated by quorum sensing
(QS) signaling it is hypothesized that YtnP
lactonase prolongs the life span of C. elegans
by downregulating the QS and expression of
virulence factors of MMA83. The protective effects
of YtnP lactonase against MMA83-induced
pathogenicity in C. elegans, coupled with its absence
of cytotoxicity, position YtnP lactonase as
a promising prophylactic agent with antivirulence
properties.

AB  - Echinococcus, tapeworms of the Taeniidae family, can infect humans and animals and cause
serious, even lethal disease. Global population genetics data suggests that disease presentation,
severity, immune response, as well as relative host susceptibility and resistance to infection
depend on the species, genotype and haplotype. The species of significant clinical relevance in
Europe are E. granulosus, the causative agent of cystic echinococcosis (CE) and E. multilocularis,
which causes the most severe disease, alveolar echinococcosis (AE). Analysis of the population
genetics of Echinococcus is an ongoing effort in some parts of Europe, while the Balkans
represent a significant knowledge gap. This project aims to comprehensively survey the entire
transmission cycle consisting of intermediate and definitive animal hosts and the environment
using sample processing and analytical methods which have been standardized, validated and
harmonized at the EU level to obtain high quality population genetics data via mitochondrial gene
(cox1 and nad1) sequencing and characterization of the EmsB microsatellite from single eggs,
worms and protoscolices. As a main novelty, comprehensive Echinococcus population genetics
data, through a survey of underexplored reservoirs with a high transmission capacity to humans,
will be systematized and graphically displayed through an interactive bioinformatics database,
WormProfiler, with a user interface tailored to physicians and veterinarians. The impact of the
project is the translation of population genetics data to physicians and veterinarians, key
stakeholders for transmission prevention to facilitate education of the public and raise awareness
of echinococcosis. The project should provide the insight into the genetic diversity of
Echinococcus and identification of transmission foci, as well as a software supported framework
for systematic surveillance and future development of targeted transmission control actions to
reduce echinococcosis case burden.

AB  - Antimicrobial resistance is a global threat, leading to an alarming increase in the prevalence of bacterial infections that can no longer be treated with available antibiotics. The World Health Organization estimates that by 2050 up to 10 million deaths per year could be associated with antimicrobial resistance, which would equal the annual number of cancer deaths worldwide. To overcome this emerging crisis, novel anti-bacterial compounds are urgently needed. There are two possible approaches in the fight against bacterial infections: a) targeting structures within bacterial cells, similar to existing antibiotics; and/or b) targeting virulence factors rather than bacterial growth. Here, for the first time, we provide a comprehensive overview of the key steps in the evaluation of potential new anti-bacterial and/or anti-virulence compounds. The methods described in this review include: a) in silico methods for the evaluation of novel compounds; b) anti-bacterial assays (MIC, MBC, Time-kill); b) anti-virulence assays (anti-biofilm, anti-quorum sensing, anti-adhesion); and c) evaluation of safety aspects (cytotoxicity assay and Ames test). Overall, we provide a detailed description of the methods that are an essential tool for chemists, computational chemists, microbiologists, and toxicologists in the evaluation of potential novel antimicrobial compounds. These methods are cost-effective and have high predictive value. They are widely used in preclinical studies to identify new molecular candidates, for further investigation in animal and human trials.

AB  - Astrocytes are the main homeostatic cells in the central nervous system, with the unique ability to transform from quiescent into a reactive state in response to pathological conditions by reacquiring some precursor properties. This process is known as reactive astrogliosis, a compensatory response that mediates tissue damage and recovery. Although it is well known that SOX transcription factors drive the expression of phenotype-specific genetic programs during neurodevelopment, their roles in mature astrocytes have not been studied extensively. We focused on the transcription factors SOX2 and SOX9, shown to be re-expressed in reactive astrocytes, in order to study the reactivation-related functional properties of astrocytes mediated by those proteins. We performed an initial screening of SOX2 and SOX9 expression after sensorimotor cortex ablation injury in rats and conducted gain-of-function studies in vitro using astrocytes derived from the human NT2/D1 cell line. Our results revealed the direct involvement of SOX2 in the reacquisition of proliferation in mature NT2/D1-derived astrocytes, while SOX9 overexpression increased migratory potential and glutamate uptake in these cells. Our results imply that modulation of SOX gene expression may change the functional properties of astrocytes, which holds promise for the discovery of potential therapeutic targets in the development of novel strategies for tissue regeneration and recovery.

AB  - Recognizing that metal ions play an important role in modifying the pharmacological properties of known organic-based drugs, the present manuscript addresses the complexation of the antifungal agent voriconazole (vcz) with the biologically relevant silver(I) ion as a strategy for the development of new antimycotics. The synthesized silver(I) complexes with vcz were characterized by mass spectrometry, IR, UV–Vis and NMR spectroscopy and single-crystal X-ray diffraction analysis. The crystallographic results showed that complexes {[Ag(vcz)(H2O)]CH3SO3}n (1), {[Ag(vcz)2]BF4}n (2) and {[Ag(vcz)2]PF6}n (3) have polymeric structures in the solid state, in which silver(I) ions have a distorted tetrahedral geometry. On the other hand, DFT calculations revealed that the investigated silver(I) complexes 1–3 in DMSO exist as linear [Ag(vcz-N2)(vcz-N19)]+ (1a), [Ag(vcz-N2)(vcz-N4)]+ (2a) and [Ag(vcz-N4)2]+ (3a) species, respectively. The evaluated complexes showed an enhanced anti-Candida activity compared to the parent drug with minimal inhibitory concentration (MIC) values in the range of 0.02–1.05 μM. In comparison with vcz, the corresponding silver(I) complexes showed better activity in prevention hyphae and biofilm formation of C. albicans, indicating that they could be considered as promising agents against Candida that significantly inhibit its virulence. Also, these complexes are much better inhibitors of ergosterol synthesis in the cell membrane of C. albicans at the concentration of 0.5 × MIC. This is also confirmed by a molecular docking, which revealed that complexes 1a – 3a showed better inhibitory activity than vcz against the sterol 14α-demethylase enzyme cytochrome P450 (CYP51B), which plays a crucial role in the formation of ergosterol.

AB  - 22q11.2 deletion syndrome (22q11.2DS), the most frequent microdeletion syndrome in humans, is related to a high risk of developing neurodevelopmental disorders. About 95% of patients with 22q11.2DS have speech and language impairments. Global articulation, story generation, and verbal memory tests were applied to compare articulatory characteristics of speech sounds, spontaneous language abilities, and immediate verbal memory between four groups of Serbian-speaking children: patients with 22q11.2DS, children with clinical presentation of 22q11.2DS that do not have the microdeletion, children with non-syndromic congenital heart defects, and their peers with typical speech–sound development. The obtained results showed that children with this microdeletion have impaired articulation skills and expressive language abilities. However, we did not observe weaker receptive language skills and immediate verbal memory compared to healthy controls. Children with 22q11.2DS should be considered a risk category for the development of speech–sound pathology and expressive language abilities. Since speech intelligibility is an instrument of cognition and adequate peer socialization, and language impairment in school-aged children with 22q11DS might be an indicator of increased risk for later psychotic symptoms, patients with 22q11.2 microdeletion should be included in a program of early stimulation of speech–language development immediately after diagnosis is established.

AB  - Alterations in gut microbiota and deregulation
of the gut immune system are recognized
as important events in autoimmune diseases.
The knowledge about the important role of anaerobic
gut bacteria that produce short-chain
fatty acids (SCFAs), in the regulation of intestinal
barrier and immune response made a way
for the development of microbiota-based interventions.
Our research aimed to isolate the
strains with the potential to produce SCFAs,
from healthy volunteer fecal material, and to
test their effects on IL-8 production in the culture
of intestinal epithelial cells (Caco2) as an in
vitro system imitating initial intestinal inflammation,
the effects on the expression of neuronal
activity-regulated genes of Caenorhabditis
elegans, and the effect on the development
of experimental autoimmune encephalomyelitis
(EAE), a mouse model of multiple  sclerosis.
Three isolated butyric acid (BA)-producing
strains, and three acetic acid (AA)-producing
strains diminished the production of IL-8 in Caco-
2 cells treated with IL-1β/TNF-α. Further, all
BA-producing strains stimulated the expression
of important neuro-related genes in C. elegans.
Based on the strongest effects in these
assays an isolate identified as Faecalimonas sp.
NGB245 strain was further tested in EAE model.
The oral treatment of EAE-induced mice with
this strain for 16h per day for 15 days resulted
in alleviated daily clinical scores, maximal
clinical scores, and the duration of the illness
in comparison to the effect of media used for
strain cultivation. These results point to the potential
of NGB245 to modify the gut-brain axis
opening the field for future development of microbiota-
based therapy for the diseases associated
with immune response dysfunctions.

AB  - GlucoAdjust project aims to solve fast-growing health challenges important for the society,
namely it will focus on discovery of new treatments for one rare disease glycogen storage
disease type Ib (GSD Ib) and one common disease diabetes mellitus type 2 (DM type 2). We
propose a completely new concept based on the identification of small molecule (SM)
compounds able to directly bind to glucose-6-phospate translocase (G6PT) and thus fine-tune
glucose level. To tackle these challenges, an interdisciplinary international team will screen large
library of SMs combining in silico and in vitro approaches and identify SMs that directly bind to
G6PT. SMs able to stabilize G6PT and increase its function thus correcting hypoglycemia are
potential drugs for GSD Ib. On the other hand, SMs that inhibit G6PT may be used to induce
hypoglycemia in DM type 2 treatment. To obtain highly functional results of testing SMs in vitro,
human hepatocyte models for GSD Ib and DM type 2 as well as controls will be developed
(differentiated from human healthy and GSD Ib iPSC and diabetic adipose stem cells). For the
first time, whole transcriptome of human GSD Ib hepatocytes will be used to delineate molecular
processes disturbed due to G6PT deficiency. As a result, RNA hallmarks of GSD Ib phenotype will
be determined and used for evaluation of SMs’ effect in both models. To be efficient for GSD Ib,
SMs will have to revert GSD Ib phenotype into normal. The key to discover satisfactorily
effective, yet sufficiently mild inhibitor for DM type 2 will be to avoid hallmarks representing
GSD Ib phenotype. Thus, a revolutionary concept of using GSD Ib as a model of hypoglycemia to
better optimize DM type 2 treatment is proposed here. Results will be openly disseminated to
make a wide scientific, educational, social and economic impacts. GlucoAdjust anticipates
innovative results with a potential to be further translated into drugs able to improve lives of
people with GSD Ib and DM type 2 worldwide.

AB  - Nonsteroidal anti-inflammatory drugs (NSAIDs) alleviate inflammation and pain through the inhibition of cyclooxygenase (COX) enzymes. Besides these widely recognized therapeutic utilizations, NSAIDs have been reported to display moderate antimicrobial activity and enhance antimicrobial efficacy when administered in combination with commercial antimicrobial drugs. In the present study, we designed novel potential antimicrobial agents by linking some NSAIDs (ibuprofen, flurbiprofen, and naproxen) to various azole rings (pyrazole, imidazole, triazole, and benzimidazole) via hydrazone functionality. The hydrazone linker was introduced into the chemical scaffold of the title molecules by the reaction between hydrazides obtained from NSAIDs and in-house synthesized azole-carrying benzaldehydes. The structures of the target compounds were elucidated by a combination of spectral methods. The NOESY spectra and stereochemical analyses performed using DFT method confirmed the presence of the target molecules as a mixture of E(C=N)-E(N-N)-synperiplanar and E(C=N)-E(N-N)-antiperiplanar conformers in DMSO-d6 solution. 1H and 13C NMR chemical shift values in DMSO were calculated using the GIAO method and compared with the experimental NMR data. Finally, some derivatives were demonstrated to inhibit Candida albicans filamentation and/or bacterial communication system known as quorum sensing. For COX inhibitor-azole hybrids with antimicrobial potency, naproxen appeared to be the most appropriate NSAID, while bulky benzimidazole was not found as a preferable azole ring.

AB  - In contrast to humans, zebrafish have a remarkable ability to regenerate their hearts after injury, while both humans and zebrafish efficiently repair the wounded skeletal muscle. Common players in these two processes might represent potential targets for the development of efficient therapies to stimulate human heart to regenerate after injury. We identified ankrd1a expression to be upregulated in both regenerating zebrafish hearts and in repairing skeletal muscle. Its mammalian homolog ANKRD1/CARP encodes a stress responsive cardiac ankyrin repeat protein involved in transcriptional regulation, sarcomere assembly and mechanosensing. Using a TgBAC(ankrd1a:EGFP) line, we showed that activation of ankrd1a in cryoinjured heart is restricted to border zone cardiomyocytes, implicating this gene in dedifferentiation and proliferation of regenerating cardiomyocytes. After stab wound injury of skeletal muscle expression of the fluorescent reporter was observed from 3 dpi, when new EGFP-positive muscle cells emerged inside the injury zone. At later time points, EGFP-positive myofibers were visible in the deeper tissue layers, concomitant with active repair of the injured tissue. In cryoinjured skeletal muscle, strong activation of ankrd1a was also observed in myofibers adjacent to the injury, and in those on uninjured side. Detection of the transgene in both newly formed myofibers that invade the wound and in the apparently uninjured tissue surrounding the injury suggests the role of ankrd1a in skeletal muscle tissue repair and adaptive processes in uninjured myofibers surrounding the injury site. Our results implicate ankrd1a in zebrafish muscle regeneration, repair and remodeling, promoting it as an attractive target for translational studies, as a player in muscle healing and as a sensor of stressed muscle.

AB  - Introduction: Lipid nanovesicles associated with bioactive phytochemicals from spruce needle homogenate (here called nano-sized
hybridosomes or nanohybridosomes, NSHs) were considered.
Methods: We formed NSHs by mixing appropriate amounts of lecithin, glycerol and supernatant of isolation of extracellular vesicles
from spruce needle homogenate. We visualized NSHs by light microscopy and cryogenic transmission electron microscopy and
assessed them by flow cytometry, dynamic light scattering, ultraviolet–visual spectroscopy, interferometric light microscopy and liquid
chromatography–mass spectrometry.
Results: We found that the particles consisted of a bilayer membrane and a fluid-like interior. Flow cytometry and
interferometric light microscopy measurements showed that the majority of the particles were nano-sized. Dynamic light
scattering and interferometric light microscopy measurements agreed well on the average hydrodynamic radius of the
particles Rh (between 140 and 180 nm), while the concentrations of the particles were in the range between 1013 and
1014/mL indicating that NSHs present a considerable (more than 25%) of the sample which is much more than the yield of
natural extracellular vesicles (EVs) from spruce needle homogenate (estimated less than 1%). Spruce specific lipids and
proteins were found in hybridosomes.
Discussion: Simple and low-cost preparation method, non-demanding saving process and efficient formation procedure suggest that
large-scale production of NSHs from lipids and spruce needle homogenate is feasible.
Plain Language Summary: Cells shed into their exterior nanoparticles (here referred to as extracellular vesicles – EVs) that
are free to move, reach distant cells and are taken up by them. As they carry bioactive constituents, EVs may have important
impact on the recipient cells. The mechanisms of EV formation and mediation can be employed in designing therapeutic,
prophylactic and diagnostic methods for various medical issues. EVs can be harvested from biological samples; however,
their yield is small,12 and there are potential side effects. Artificial vesicles – liposomes – have high yield; however, in vivo,
they can be degraded before reaching the target and their reproducibility is yet insufficient. In order to combine advantages of
both types of nanoparticles, we have composed nanohybridosomes (NSHs) from soya lecithin, water and supernatant of
isolation of EVs from spruce needle homogenate, visualized them by cryogenic electron microscopy and characterized them
with respect to their size, concentration and protein/nucleic acid content. We have applied a recently developed interferometric light microscopy to determine the hydrodynamic radius and the concentration of EVs. We found that the majority of
composed particles are nano-sized and that they enclose more than 25% of the incoming volume of liquid, which is considerably more than about 1% that can be harvested by isolation of EVs from spruce needle homogenate by (ultra)
centrifugation

AB  - Neurodevelopmental disorders (NDDs) are caused by alterations in early brain development. They are a group of geographically dispersed, complex and heterogeneous disorders that give rise to the psychiatric conditions such as autism spectrum disorders, intellectual disability, schizophrenia and bipolar disorder. In order to build global research activity for study of NDDs, the main goals of the Twinning project STREAMLINE are to enhanced strategic networking and reinforce research and innovation potential of the Institute of Molecular Genetics and Genetic Engineering, University of Belgrade (IMGGE) in order to develop IMGGE as a high capacity hub for research of NDDs in the Western Balkans. This will be achieved by twinning IMGGE with three top-class research institutions in Europe (Cardiff University, University of Maastricht and Centre for Research and Technology Hellas) with an exceptional expertise in the stem cells based research of NDDs, -OMICS technologies, bioinformatics data analysis and drug testing and through staff exchanges, training, and organization of summer schools, Industry Open Days, symposia and workshops.

AB  - The formation of biofilms by foodborne pathogens
is a constant challenge in the food industry,
leading to an increased risk of contamination and
compromising food safety. Many of the chemicals
commonly used for sanitation in the food industry
are unable to remove biofilms, are harmful
to surfaces and can be toxic. The effectiveness
of disinfectants can be improved using enzymes
that specifically target biofilm components such
as exopolysaccharides, extracellular DNA, or proteins.
In this study we investigated the potential
of glycoside hydrolases originating from the
gill microbiota of freshwater fish to control biofilm
formation in the most common foodborne
pathogens. We demonstrated that β-glucosidase
from Microbacterium sp. BG28 (BglB-BG28) effectively
inhibits cellulose-rich biofilms formed by
Salmonella enteritidis, S. typhimurium, S. infantis,
and Escherichia coli. When these bacteria were cultivated overnight with 200 μL/mL enzyme, up
to 80% less biofilm was formed. By fluorescence
microscopy, we visualised the inhibition of biofilms
on plastic, glass and aluminium, materials
commonly used in the food industry. When used
as a pre-treatment, BglB-BG28 increased the
bactericidal efficacy of Oxicid®S, a commercially
available surface disinfectant. Its effectiveness at
temperatures up to 50 °C and in a pH range from
4 to 8 together with compatibility with non-ionic
detergents and high tolerance to sodium chloride
and glucose give BglB-BG28 advantages in
harsh and diverse industrial environments. Importantly,
no toxicity to Caenorhabditis elegans
was observed at enzyme concentrations of up
to 1 mg/ml. Overall, these results demonstrate
the suitability of the β-glucosidase BglB-BG28 for
the formulation of a novel enzyme-based disinfectant
to be used in food processing facilities.

AB  - Fungal infections, once considered a rare disease,
have become an everyday problem in modern
societies, posing major challenges to global
health. It is estimated that more than one billion
people are affected by fungal infections and 1.6
million people succumb to these diseases every
year. Of the 600 species of fungi capable of causing
infections in humans, species of the genus
Candida cause more than 85% of infections, especially
C. albicans, which has become a serious
threat to human health in immunocompromised
and immunosuppressed individuals. Unfortunately,
the current arsenal of clinical drugs relies
on only four classes of approved drugs (polyenes,
azoles, echinocandins and allylamines), which
are only partially effective, resulting in incomplete
eradication of the fungal infection. In
addition, the serious side effects, ranging from
systemic or organ-specific toxicity to poor bioavailability
and low activity, significantly hamper
the clinical use of antifungals. These problems
call for new effective and safe antifungal agents,but also for appropriate preclinical models to accurately
study potential adverse effects on the
human population and test their efficacy against
fungal infections. In this sense, zebrafish (Danio
rerio) embryos have become one of the most
powerful preclinical animal models in infection
biology and drug discovery, offering the unique
opportunity to simultaneously monitor the safety
and efficacy of the applied molecule in real
time. With the aim of providing a preclinical platform
for the identification of new safe antifungal
drugs to effectively control C. albicans infection,
we comprehensively tested the toxicity of 13
clinical antifungal drugs in the zebrafish embryo
model. The 21 toxicity endpoints, including
survival, teratogenicity, cardiotoxicity and hepatotoxicity,
were evaluated and compared with
adverse effects described in rats and humans. Of
the clinical drugs, the efficacy of fluconazole and
voriconazole was evaluated in the zebrafish - C.
albicans model of systemic and wound biofilm
infection.

AB  - The increasing prevalence of multidrug-resistant
(MDR) Acinetobacter baumannii limits effective
therapeutic options, and tigecycline has been
considered one of the last resort therapies for
MDR A. baumannii infections. Nevertheless, A.
baumannii isolates resistant to tigecycline are
becoming increasingly reported, mostly due to
overexpression of efflux pumps. The three major
RND efflux systems conferring tigecycline resistance
in A. baumannii are AdeABC, AdeFGH, and
AdeIJK, and their expression is regulated by the
two-component system AdeRS, the LysR-type
regulator AdeL, and the TetR-type regulator AdeN,
respectively. Following the above, we aimed
to determine the role of efflux pumps in tigecycline
resistance of thirty-seven A. baumannii isolates
collected from Western Balkan healthcare
settings (Serbia, Bosnia and Herzegovina and
Montenegro) in 2016 and 2022. The majority of
isolates belonged to the most prevalent international
clonal lineage IC2 (n = 32), four isolates are
members of IC1, while only one isolate is identified
as IC3. All tested isolates demonstrated a
significant decrease in tigecycline MIC in presence
of efflux pump inhibitor CCCP (≥16-fold reduction)
indicating that mechanism responsible
for tigecycline resistance is antibiotic efflux. The
comparison of target efflux pump regulatory
proteins, translated from nucleotide sequences,
to reference strains ATCC19606 and ATCC17978
revealed that most of the isolates have G186V
and N268H alternations in AdeS (n = 32), while
most common changes in AdeR were V120I and
A136V (n = 29) as described in previous studies.
Substitution Q262R was detected exclusively in
AdeL proteins of IC1 isolates, while no mutations
were observed within AdeN regulators. Expression
of the adeB, adeG, and adeJ genes in six selected
isolates was upregulated in four (1,4- to
3-fold), six (1,6- to 2,6-fold), and three isolates
(1,7- to 4-fold), respectively. This study confirmed
that overexpression of efflux pump encoding
genes enables tigecycline resistance in clinical
A. baumannii isolates.

AB  - The discovery and engineering of novel biocatalysts capable of depolymerizing polyethylene terephthalate (PET) have gained significant attention since the need for green technologies to combat plastic pollution has become increasingly urgent. This study focuses on the development of novel substrates that can indicate enzymes with PET hydrolytic activity, streamlining the process of enzyme evaluation and selection. Four novel substrates, mimicking the structure of PET, were chemically synthesized and labeled with fluorogenic or chromogenic moieties, enabling the direct analysis of candidate enzymes without complex preparatory or analysis steps. The fluorogenic substrates, mUPET1, mUPET2, and mUPET3, not only identify enzymes capable of PET breakdown but also differentiate those with exceptional performance on the polymer, such as the benchmark PETase, LCCICCG. Among the substrates, the chromogenic p-NPhPET3 stands out as a reliable tool for screening both pure and crude enzymes, offering advantages over fluorogenic substrates such as ease of assay using UV–vis spectroscopy and compatibility with crude enzyme samples. However, ferulic acid esterases and mono-(2-hydroxyethyl) terephthalate esterases (MHETases), which exhibit remarkably high affinity for PET oligomers, also show high catalytic activity on these substrates. The substrates introduced in this study hold significant value in the function-based screening and characterization of enzymes that degrade PET, as well as the the potential to be used in screening mutant libraries derived from directed evolution experiments. Following this approach, a rapid and dependable assay method can be carried out using basic laboratory infrastructure, eliminating the necessity for intricate preparatory procedures before analysis.

AB  - Alpha-ketoglutarate (αKG) emerged as a key regulator of energetic and redox metabolism in cells, affecting the immune response in various conditions. However, it remained unclear how the exogenous αKG modulates the functions of dendritic cells (DCs), key cells regulating T-cell response. Here we found that non-toxic doses of αKG display anti-inflammatory properties in human APC-T cell interaction models. In a model of monocyte-derived (mo)DCs, αKG impaired the differentiation, and the maturation of moDCs induced with lipopolysaccharide (LPS)/interferon (IFN)-γ, and decreased their capacity to induce Th1 cells. However, αKG also promoted IL-1β secretion by mature moDCs, despite inflammasome downregulation, potentiating their Th17 polarizing capacity. αKG induced the expression of anti-oxidative enzymes and hypoxia-induced factor (HIF)-1α in moDCs, activated Akt/FoxO1 pathway and increased autophagy flux, oxidative phosphorylation (OXPHOS) and glycolysis. This correlated with a higher capacity of immature αKG-moDCs to induce Th2 cells, and conventional regulatory T cells in an indolamine-dioxygenase (IDO)-1-dependent manner. Additionally, αKG increased moDCs’ capacity to induce non-conventional T regulatory (Tr)-1 and IL-10-producing CD8+T cells via up-regulated immunoglobulin-like transcript (ILT3) expression in OXPHOS-dependent manner. These results suggested that exogenous αKG-altered redox metabolism in moDCs contributed to their tolerogenic properties, which could be relevant for designing more efficient therapeutic approaches in DCs-mediated immunotherapies.

AB  - The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), responsible for the COVID-19 pandemic, has been evolving rapidly causing emergence of new variants and health uncertainties. Monitoring the evolution of the virus was of the utmost importance for public health interventions and the development of national and global mitigation strategies. Here, we report national data on the emergence of new variants, their distribution, and dynamics in a 3-year study conducted from March 2020 to the end of January 2023 in the Republic of Serbia. Nasopharyngeal and oropharyngeal swabs from 2,398 COVID-19-positive patients were collected and sequenced using three different next generation technologies: Oxford Nanopore, Ion Torrent, and DNBSeq. In the subset of 2,107 SARS-CoV-2 sequences which met the quality requirements, detection of mutations, assignment to SARS-CoV-2 lineages, and phylogenetic analysis were performed. During the 3-year period, we detected three variants of concern, namely, Alpha (5.6%), Delta (7.4%), and Omicron (70.3%) and one variant of interest—Omicron recombinant “Kraken” (XBB1.5) (<1%), whereas 16.8% of the samples belonged to other SARS-CoV-2 (sub)lineages. The detected SARS-CoV-2 (sub)lineages resulted in eight COVID-19 pandemic waves in Serbia, which correspond to the pandemic waves reported in Europe and the United States. Wave dynamics in Serbia showed the most resemblance with the profile of pandemic waves in southern Europe, consistent with the southeastern European location of Serbia. The samples were assigned to sixteen SARS-CoV-2 Nextstrain clades: 20A, 20B, 20C, 20D, 20E, 20G, 20I, 21J, 21K, 21L, 22A, 22B, 22C, 22D, 22E, and 22F and six different Omicron recombinants (XZ, XAZ, XAS, XBB, XBF, and XBK). The 10 most common mutations detected in the coding and untranslated regions of the SARS-CoV-2 genomes included four mutations affecting the spike protein (S:D614G, S:T478K, S:P681H, and S:S477N) and one mutation at each of the following positions: 5′-untranslated region (5’UTR:241); N protein (N:RG203KR); NSP3 protein (NSP3:F106F); NSP4 protein (NSP4:T492I); NSP6 protein (NSP6: S106/G107/F108 - triple deletion), and NSP12b protein (NSP12b:P314L). This national-level study is the most comprehensive in terms of sequencing and genomic surveillance of SARS-CoV-2 during the pandemic in Serbia, highlighting the importance of establishing and maintaining good national practice for monitoring SARS-CoV-2 and other viruses circulating worldwide.

Nasopharyngeal and oropharyngeal swabs from 2,398 COVID-19- positive patients were collected and sequenced using three different next generation technologies: Oxford Nanopore, Ion Torrent, and DNBSeq. In the subset of 2,107 SARS-CoV-2 sequences which met the quality requirements, detection of mutations, assignment to SARS-CoV-2 lineages, and phylogenetic analysis were performed. During the 3-year period, we detected three variants of concern, namely, Alpha (5.6%), Delta (7.4%), and Omicron (70.3%) and one variant of interest—Omicron recombinant “Kraken” (XBB1.5) (<1%), whereas 16.8% of the samples belonged to other SARS-CoV-2 (sub)lineages. The detected SARS-CoV-2 (sub)lineages resulted in eight COVID-19 pandemic waves in Serbia, which correspond to the pandemic waves reported in Europe and the United States. Wave dynamics in Serbia showed the most resemblance with the profile of pandemic waves in southern Europe, consistent with the southeastern European location of Serbia. The samples were assigned to sixteen SARS-CoV-2 Nextstrain clades: 20A, 20B, 20C, 20D, 20E, 20G, 20I, 21J, 21K, 21L, 22A, 22B, 22C, 22D, 22E, and 22F and six different Omicron recombinants (XZ, XAZ, XAS, XBB, XBF, and XBK). The 10 most common mutations detected in the coding and untranslated regions of the SARS-CoV-2 genomes included four mutations affecting the spike protein (S:D614G, S:T478K, S:P681H, and S:S477N) and one mutation at each of the following positions: 5′-untranslated region (5’UTR:241); N protein (N:RG203KR); NSP3 protein (NSP3:F106F); NSP4 protein (NSP4:T492I); NSP6 protein (NSP6: S106/G107/F108 - triple deletion), and NSP12b protein (NSP12b:P314L). This national-level study is the most comprehensive in terms of sequencing and genomic surveillance of SARS-CoV-2 during the pandemic in Serbia, highlighting the importance of establishing and maintaining good national practice for monitoring SARS-CoV-2 and other viruses circulating worldwide.",

AB  - Skin microbiome emerged as an important
factor which can balance tissue repair process
and wound healing. Recent evidence suggest
that intracellular bacterial localization could be
associated with the aberrant healing observed
in patients with chronic wounds, while therapeutics
targeting intracellular bacteria remain
limited. Probiotic lactobacilli and their bioactive
lysates (postbiotics) are well known for their role
in maintenance of gut epithelial homeostasis.
Hence, in this study we focused to understand
the mechanisms of cutaneous response to fourteen
postbiotics derived from different lactobacilli
to reduce intracellular Staphylococcus aureus
colonization and promote healing. Latilactobacillus
curvatus BGMK2-41 demonstrated the
most efficient capability to reduce intracellular infection by S. aureus in keratinocytes in vitro and
infection of human skin explants. Reduction of
bacterial number was followed by upregulation
of the expression of antimicrobial response
genes. Furthermore, BGMK2-41 postbiotic treatment
stimulates keratinocyte migration in vitro
and increases expression of anti-inflammatory
cytokine IL-10, promotes wound closure and
strengthens the epidermal barrier via upregulation
of tight junction proteins in a human ex vivo
wound model. Altogether, this study provided
evidence that postbiotics could stimulate fortification
of epithelial barrier to suppress dissemination
of intracellular pathogens which can be
used as a novel approach to treat dermatologic
and wound healing disorders associated with
persistent infections.

AB  - During 2024, IMGGE researchers will continue exploring following areas:
- human molecular genetics and genomics,
- microbiology and ecology of microorganisms,
- plant molecular biology.
IMGGE researchers will focus on studying molecular mechanisms responsible for the
occurrence of selected rare and non-contagious diseases, as well as on identification of
molecular markers important for diagnosis, prognosis, therapy and prevention. Disease
modeling methodology will be developed using in vitro model systems (2D and 3D primary and
permanent cell lines, induced pluripotent stem cells) and in vivo model systems that include
different animal models. These stydies will aim at discovering the causes of the disease,
identifying new therapeutic targets, testing new therapeutics as well as individual response to
existing therapeutics.
During 2024, the existing IMGGE collection of microorganisms will be further expanded with
new isolates (industrial microorganisms, clinically relevant pathogens, and bacteriophages), and
IMGGI collaborators will devote themselves to studying the antimicrobial and antiviral potential
and application of new isolates, as well as mechanisms of resistance and virulence. The
genomes of selected microorganisms will be sequenced and analyzed to identify new genes of
interest, e.g. producers of bioactive proteins, enzymes and biosynthetic pathways.
Metagenomes of selected environmental or clinical samples will also be sequenced and
analyzed in order to study the biological diversity of complex communities of microorganisms.
When it comes to the molecular biology of plants, the response mechanisms of different model
organisms to abiotic and biotic stress will further be investigated. IMGGE researchers will
analyze the role of different proteins in maintaining cell homeostasis (eg LEA) and genome
stability (Ustilago maydis). The genomes, epigenomes and proteomes of the muscat flower will
be sequenced in order to study the response to stress.

AB  - Spinal muscular atrophy (SMA) is the prevalent genetic cause of childhood mortality.  Pioneering treatments yield utmost advantages only within the presymptomatic phase,  underlining the medical and ethical significance of newborn screening. 
In 2022, the Centre for Human Molecular Genetics initiated a pilot study of the newborn  screening for SMA, working closely alongside the University Children’s Hospital Tirsova  and Association SMA Serbia. The aim was to lay the foundation for the implementation  of statewide newborn screening for SMA in Serbia by conducting screening for ~8000  infants from the Obstetrics and Gynaecology Clinic Narodni Front over the course of a  year. In the subsequent year, we expanded the initiative to include another maternity  hospital located outside Belgrade, introducing sample shipment via postal services and  extending screening accessibility to a greater number of infants. 
In the initial year, 6 950 newborns underwent testing, revealing SMA in two unrelated  infants. Subsequently, an older sibling of the first newborn, although asymptomatic at  the time, was also tested at the age of 16 months, and SMA diagnosis was confirmed  in this child as well. All three children received therapeutic interventions in <1 month  from birth. To date, they have exhibited no signs of SMA, and there have been no false 
negative outcomes among the newborns who tested negative during the screening. In
the second year, an additional 5 000 newborns underwent testing. As frontrunners in this field in Serbia, we orchestrated harmonized efforts across  various tiers of healthcare, established screening and diagnostic algorithms and  follow-up protocols. Our extensive efforts were primarily aimed at elevating awareness  among all stakeholders about the critical importance of early disease detection.  In this transformative journey, we transitioned from being isolated individuals and  visionaries who championed a singular idea to an entire community and nation that now  acknowledges the paramount significance of newborn screening. As a result, a total of  11 950 infants underwent testing during the 17-month pilot project, culminating in the  rapid incorporation of newborn screening for SMA into the national screening program,  effective as of September 14th 2023. 
Timely detection and treatment can transform SMA into a manageable condition, and  there is substantial evidence supporting its inclusion in state-wide screening programs.

AB  - SalmonellaEnteritidis is the most commonly reported pathogen for foodborne illness outbreaks in both underdeveloped and developed regions. S. Enteritidis biofilms, which form on various food contact surfaces, are resistant to conventional physical and chemical cleaning and disinfection procedures routinely used in food processing. The aim of this study was to identify novel, industrially applicable enzymes that are active against S. Enteritidis biofilms. We describe the properties and anti-biofilm activity of heterologously expressed β-glucosidase B derived from the environmental strain Microbacterium sp. BG28 (BglB-BG28) collected from gills of bream fish. The enzyme inhibited adhesion and the early stages of biofilm formation in clinical isolates of S. Enteritidis. At a concentration of 200 μg/mL, BglB-BG28 effectively reduced biofilm formation, by decreasing biofilm biomass by 50% and metabolic activity within biofilms by 80%. The enzyme reduced the formation of air-liquid biofilms on various surfaces, including plastic, glass and metal, as observed by fluorescence microscopy. BglB-BG28 inhibited biofilm formation in Escherichia coli, another important food pathogen that also forms cellulose-rich biofilms. Using o-NPG as substrate, the enzyme showed activity at temperatures up to 50 °C and in a pH range between 4 and 8, high tolerance to sodium chloride and glucose, and compatibility with nonionic detergents. Importantly, no toxicity was observed in the model system Caenorhabditis elegans even at an enzyme concentration of 1 mg/mL. These results suggest that the β-glucosidase BglB-BG28 is a promising candidate for the development of a new enzyme-based disinfection protocol that can be used in food processing facilities.

AB  - Here, an artificial intelligence (AI)-based approach was employed to optimize the production of electrospun scaffolds for in vivo wound healing applications. By combining polycaprolactone (PCL) and poly(ethylene glycol) (PEG) in various concentration ratios, dissolved in chloroform (CHCl3) and dimethylformamide (DMF), 125 different polymer combinations were created. From these polymer combinations, electrospun nanofiber meshes were produced and characterized structurally and mechanically via microscopic techniques, including chemical composition and fiber diameter determination. Subsequently, these data were used to train a neural network, creating an AI model to predict the optimal scaffold production solution. Guided by the predictions and experimental outcomes of the AI model, the most promising scaffold for further in vitro analyses was identified. Moreover, we enriched this selected polymer combination by incorporating antibiotics, aiming to develop electrospun nanofiber scaffolds tailored for in vivo wound healing applications. Our study underscores three noteworthy conclusions: (i) the application of AI is pivotal in the fields of material and biomedical sciences, (ii) our methodology provides an effective blueprint for the initial screening of biomedical materials, and (iii) electrospun PCL/PEG antibiotic-bearing scaffolds exhibit outstanding results in promoting neoangiogenesis and facilitating in vivo wound treatment.

abstract = "Here, an artificial intelligence (AI)-based approach was employed to optimize the production of electrospun scaffolds for in vivo wound healing applications. By combining polycaprolactone (PCL) and poly(ethylene glycol) (PEG) in various concentration ratios, dissolved in chloroform (CHCl3) and dimethylformamide (DMF), 125 different polymer combinations were created. From these polymer combinations, electrospun nanofiber meshes were produced and characterized structurally and mechanically via microscopic techniques, including chemical composition and fiber diameter determination. Subsequently, these data were used to train a neural network, creating an AI model to predict the optimal scaffold production solution. Guided by the predictions and experimental outcomes of the AI model, the most promising scaffold for further in vitro analyses was identified. Moreover, we enriched this selected polymer combination by incorporating antibiotics, aiming to develop electrospun nanofiber scaffolds tailored for in vivo wound healing applications. Our study underscores three noteworthy conclusions: (i) the application of AI is pivotal in the fields of material and biomedical sciences, (ii) our methodology provides an effective blueprint for the initial screening of biomedical materials, and (iii) electrospun PCL/PEG antibiotic-bearing scaffolds exhibit outstanding results in promoting neoangiogenesis and facilitating in vivo wound treatment.",
