Vitiligo is an autoimmune disorder characterised by melanocyte cytotoxicity. The aim of this study was to examine the role of the Th17 pathway in the pathogenesis of vitiligo. The three components of the pathway were evaluated using plasma interleukin (IL6), IL23, and IL10 for the modulatory component,\n STAT3<\/jats:italic>\n and\n RORC<\/jats:italic>\n gene expression for the mediator component, and plasma IL17A for the effector component.\n <\/jats:p>\n <\/jats:sec>\n \n Method:<\/jats:title>\n \n The study was carried out using a case-control design. The case group comprised patients diagnosed with vitiligo (\n n<\/jats:italic>\n = 30), whereas the control group comprised healthy volunteers (\n n<\/jats:italic>\n = 30). The plasma cytokine levels were measured by enzyme-linked immunosorbent assay. Gene expression in peripheral blood mononuclear cells was measured by real-time quantitative polymerase chain reaction.\n <\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n \n In vitiligo patients, IL6 was 2.3 times higher (\n P<\/jats:italic>\n < 0.001), IL23 was 1.1 times higher (\n P<\/jats:italic>\n = 0.18), and IL10 was 2.5 times lower (\n P<\/jats:italic>\n < 0.001). The fold change in the expression of the\n STAT3<\/jats:italic>\n gene was 2.27 times (\n P<\/jats:italic>\n < 0.01) and that of the\n RORC<\/jats:italic>\n gene was 3.8 times (\n P<\/jats:italic>\n < 0.001) in vitiligo patients. Plasma IL17A was 1.6 times higher (\n P<\/jats:italic>\n < 0.001) in vitiligo patients.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions:<\/jats:title>\n Together, these results indicate that the Th17 pathway is likely to be overactive in vitiligo due to dysregulation.<\/jats:p>\n
