Background Vitiligo is a specific type of idiopathic acquired or inherited leukoderma which is characterized by patterned/circumscribed hypomelanosis of the skin and hair, with complete absence of melanocytes. The aetiology of vitiligo is unknown, several hypotheses have been proposed to explain its pathogenesis and a convergence theory was proposed which assumes that all hypotheses are not mutually exclusive. In vivo, immunohistochemical studies of perilesional area of active lesions in generalized vitiligo mainly detects predominant CD8+ and to lesser extent CD4+ T cells in the infiltrate, which express activation molecules such as the skin homing receptor; CLA antigen and the IL-17. IL17 mRNA is up-regulated in the blood of vitiligo patients therefore, it has been suggested as a crucial regulator of vitiligo. Aim of work In this study, we focused primarily on the regulatory pathways and role of IL-17 in vitiligo by determination of the level of expression of IL17 mRNA by Real-time RT-PCR.
