摘要
T helper 17 (Th17) cells are characterized by the secretion of IL-17, a proinflammatory cytokine. They represent a newly described T helper subpopulation that is distinct from Th1 and Th2 lineages. Because of their pleiotropic activity on fibroblasts, keratinocytes, endothelial cells, neutrophils and memory T cells, Th17 cells are thought to be crucial in mediating tissue inflammation and autoimmunity. Autoimmune diseases were classically considered as Th1-mediated disorders such as rheumatoid arthritis or %26apos;mixed%26apos; Th1/Th2 diseases such as inflammatory bowel diseases, systemic lupus erythematosus, bullous diseases, but new evidence suggests the deep involvement of Th17 cells in their pathogenesis that, potentially, may address a selective therapeutic approach targeting the IL23/Th17 pathway. This review summarizes the current knowledge of the pathogenic contribution of Th17 cells in select cutaneous autoimmune disorders, including lupus erythematosus, scleroderma, dermatomyositis, bullous pemphigoid and pemphigus vulgaris.
