With respect to the important roles of CXCL16 in vitiligo, we previously demonstrated that compared with nonlesional and healthy control skin, more CXCR6+ CD8+ T cells are located at the basal epidermis and dermis of perilesions from vitiligo patients, which is consistent with the higher content of CXCL16 in epidermis. Here, CXCL16 is linked to vitiligo.
