In situ expression of TNF-α and IL-10 in human dermatophytosis lesions due to Trichophyton rubrum

Abstract Dermatophytosis is a very common superficial mycosis, but there are few studies about the human immune response to dermatophytes. We aim to analyze the in situ expression of TNF-α and IL-10 in human dermatophytosis. Expression of TNF-α and IL-10 were evaluated in skin samples from 10 patients with dermatophytosis and 12 healthy subjects using an immunohistochemistry assay. TNF-α and IL-10 were significantly elevated in lesions from patients with dermatophytosis compared to healthy controls. These data illustrate the balance of pro- and anti-inflammatory cytokines suggesting Trichophyton rubrum infection could control the local immune response.
