CD40LG and vitiligo: Consistently, in perilesional epidermis samples, we showed the mRNA levels of CXCL10, CXCL16 (Fig. S1A) in vitiligo patients with positive anti-CMV IgM were higher than that in patients with negative anti-CMV IgM and in healthy controls, also higher than that in the apparently healthy epidermis of vitiligo patients with positive anti-CMV IgM.
