Vitiligo is an autoimmune skin disease characterized by depigmented skin as a result of melanocyte loss. Additional clinical features of vitiligo include patchy loss of skin color, premature whitening of the hair, and loss of color in the tissues (mouth and nose). The exact cause of vitiligo remains unknown, but some possible factors include genetic causes and environmental triggers that results in autoreactive CD8+ T cells that target melanocytes . The disease is maintained by melanocyte-reactive resident memory T cells (Trm) cells through an IL-15 dependent signaling pathway.
