Cytokine profile (IL‐2, IL‐6, IL‐17, IL‐22, and TNF‐α) in vitiligo—New insight into pathogenesis of disease

Our study shows that cytokines secreted by Th17 cells play an important role in maintenance and spread of vitiligo as they increase in line with extent of disease. Also TNF-α increases in proportion with activity of disease, hence may act as biomarker for identifying patient with aggressive disease.
