CXCL8 and vitiligo: Some studies reported that 8-hydroxydeoxyguanosine was increased in vitiligo under oxidative stress and inhibited the Rac-GTPases, as the neutrophil migration can also be mediated by Rac-GTPases, probably resulting in suppressing the migration of neutrophils in vitiligo even in the presence of elevated CXCL8 [29, 60, 61].
