Further, the epidermal expression of hBD-2, LL-37, and S100A7/psoriasin is decreased in patients with ATLL and dermatophytosis [74,75], indicating that the secretion of Th17-mediated antimicrobial peptides by keratinocytes is reduced, leading to the frequent occurrences of dermatophytosis. The gene discussed is CAMP; the disease is dermatophytosis.
