Dermcidin combats athlete's foot fungusMycostatic effect of recombinant dermcidin against Trichophyton rubrum and reduced dermcidin expression in the sweat of tinea pedis patients.
We explored the potential of dermcidin, a natural antimicrobial protein, in fighting off Trichophyton rubrum, the fungus responsible for athlete’s foot. Our research involved testing recombinant dermcidin to evaluate its ability to inhibit the growth of this fungus. The results were quite promising, revealing that at typical sweat levels of dermcidin—about 50 μg/mL—it was able to reduce fungal growth by 40.5%. When we ramped up the concentration to 270 μg/mL, the effect amplified significantly, with a 93.4% reduction in fungal presence.
Further analysis showed that dermcidin not only kills Trichophyton but also impacts its metabolic activity, making it less effective at thriving on the skin. Interestingly, we found that individuals suffering from tinea pedis, commonly known as athlete’s foot, had lower levels of dermcidin in their sweat compared to healthy individuals. This suggests that sufficient levels of dermcidin are critical in protecting our skin against fungal infections.
Ultimately, this study highlights dermcidin's important role in skin health, particularly its potential to prevent athlete’s foot by inhibiting the growth of the fungus. It seems that maintaining adequate levels of this protein might be key to successfully combating these infections and supporting overall skin immunity.
