Multiple IFNγ-induced chemokine genes (including CXCL9, CXCL10, and their human-specific variant CXCL11) were significantly upregulated in fibroblasts that were isolated from anatomic regions with a higher incidence of vitiligo, such as the back of the hand, the back of the foot, the chest, and the back. Here, CXCL9 is linked to vitiligo.
