CXCR3 and vitiligo: The recruitment of CD8+ T cells to skin lesions is carried out by the IFN-γ-mediated T cell chemokine receptor, C-X-C motif chemokine receptor 3 (CXCR3), and its ligands CXCL9, CXCL10, and CXCL11, which are found to be abundant in skin biopsy specimens from vitiligo patients (91).
