For example, CXCL9 and CXCL10 induced by IFN-γ play a key role in the skin migration of CD8+ T cells in vitiligo, and the expression of CXCR3 on melanocyte-specific CD8+ T cells has been detected in skin lesions and in the peripheral blood of vitiligo patients (Rashighi et al., 2014). The gene discussed is CXCL10; the disease is vitiligo.
