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  - Intracellular pathogens including Staphylococcus aureus contribute to the non-healing phenotype of chronic wounds. Lactobacilli, well known as beneficial bacteria, are also reported to modulate the immune system, yet their role in cutaneous immunity remains largely unknown. We explored the therapeutic potential of bacteria-free postbiotics, bioactive lysates of lactobacilli, to reduce intracellular S. aureus colonization and promote healing. Fourteen postbiotics derived from various lactobacilli species were screened, and Latilactobacillus curvatus BGMK2-41 was selected for further analysis based on the most efficient ability to reduce intracellular infection by S. aureus diabetic foot ulcer clinical isolate and S. aureus USA300. Treatment of both infected keratinocytes in vitro and infected human skin ex vivo with BGMK2-41 postbiotic cleared S. aureus. Keratinocytes treated in vitro with BGMK2-41 upregulated expression of antimicrobial response genes, of which DEFB4, ANG, and RNASE7 were also found upregulated in treated ex vivo human skin together with CAMP exclusively upregulated ex vivo. Furthermore, BGMK2-41 postbiotic treatment has a multifaceted impact on the wound healing process. Treatment of keratinocytes stimulated cell migration and the expression of tight junction proteins, while in ex vivo human skin BGMK2-41 increased expression of anti-inflammatory cytokine IL-10, promoted re-epithelialization, and restored the epidermal barrier via upregulation of tight junction proteins. Together, this provides a potential therapeutic approach for persistent intracellular S. aureus infections.
