Treatment with CXCL9 and CXCL11 also induced a significant melanocyte death in both healthy (P = 0.034 and P = 0.007, respectively) and vitiligo (P = P < 0.001 and P = 0.01) melanocytes that was almost completely prevented by the use of SiCXCR3B (Fig. 4d). This evidence concerns the gene CXCL9 and vitiligo.
