Moreover, Sawada et al. (67) observed that expression of epidermal hBD-2 and LL-37 was significantly lower in Adult T-cell leukemia/lymphoma (ATLL) patients with dermatophytosis than in infected non-ATLL patients, and this correlated with a significantly decreased frequency of peripheral T helper 17 (Th17) lymphocytes and lower IL-17 levels in serum. The gene discussed is IL17A; the disease is adult T-cell leukemia/lymphoma.
