Abstract
Abstract Background: Both superficial tinea and pityriasis versicolor are very popular fungal skin infections that affect people all over the world. Recent research suggests that certain antimi-crobial peptides can also play a role in the body's natural defense against fungal infection. Aim of Study: The purpose of the current research would be to investigate the tissue expression of b2-defensin mRNA in lesions of tinea versicolor and lesions of tinea circinata and hence studying its role in fungal infection pathogenesis. Patients and Methods: Twenty patients with tinea versi-color, twenty with tinea circinata, and twenty controls were included in this case control study. For real-time PCR (RT-PCR) gene expression of b2-defensin mRNA, a punch skin biopsy was obtained from the patient's lesional and non-lesional skin, as well as normal skin from a control. Results:  b2 defensin was upregulated in lesional areas of tinea versicolor and tinea circinata in comparison to non lesional areas of tinea versicolor, tinea circinata and control. These results reached a statistical significance for mRNA b2 defensin in tinea versicolor and tinea circinata (p-value <0.014). Conclusion: The results back up the theory that antimi-crobial peptides (b2-Defensin) may help the skin fight der-matophytes and M. furfur.
