Rashigi et al. reported that both vitiligo patients and mouse model of vitiligo reflect a uniquely IFN-γ specific Th1 cytokine signature in the skin that includes IFN-γ dependent chemokines such as CXCL9, CXCL10, and CXCL11 which induces T cell homing into peripheral tissues [6]. This evidence concerns the gene CXCL9 and vitiligo.
