A combination of enzyme-linked immunosorbent assay (ELISA), plate spectrofluorimetry, and flow cytometry with fluorescence dye staining, scratch assay, and real-time cell imaging techniques was used to investigate the effects of FlaB on S. aureus-infected HaCaT keratinocytes. FlaB decreased reactive oxygen species levels, nitrite oxide levels, and TNF-α and IL-18 release in S. aureus-infected HaCaT cells. FlaB reversed the inhibition of HaCaT cell proliferation caused by S. aureus infection. FlaB significantly increased keratinocyte migration and wound healing in an in vitro S. aureus-infected wound skin model. Using real-time qPCR, we found that FlaB caused a 1.7-fold reduction in agrA expression, which controls quorum sensing system in S. aureus. Bioinformatics analysis and molecular docking, together with experimental data, suggest that FlaB targets the pro/antioxidant defense system in human cells. Thus, FlaB can play a dual role as an antibacterial and pro/antioxidant machinery modulator, providing an observable positive effect in S. aureus-infected in vitro skin wounds. Staphylococcal sortase A enzyme and Arg systems are the targets of FlaB in bacterial cells. Nrf2/Bach1 dependent pro/antioxidant defense system is a target of FlaB in human cells. Some suggestions have also been made regarding the biological role of this marine fungal metabolite and its therapeutic possibilities. |
