Vitiligo: Mechanistic insights lead to novel treatments.

Vitiligo is an autoimmune disease of the skin characterized by patchy depigmentation. Current treatments are moderately effective at reversing disease by suppressing autoimmune inflammation in the skin and promoting melanocyte regeneration. Recent basic and translational research studies have significantly improved our understanding of disease pathogenesis, which is now leading to emerging treatment strategies based on targeted therapy. Here we discuss important clinical characteristics of vitiligo, current therapies and their limitations, advances in understanding disease pathogenesis, emerging targeted treatments, and strategies to optimize clinical trials to efficiently and effectively test these new treatments.
