Furthermore, we compared the relative proportion changes in each cell subpopulation between the patients with vitiligo and healthy group; compared with those in the healthy group, the proportions of C27 (mast cells), C8 (memory CD8 + T cells), C14/C20 (CD8 + NKT cells), and C4 (memory CD4 + T cells) cell subgroups increased in the patients with vitiligo, whereas C26/C12 (melanocytes) and almost all keratinocytes were reduced (Fig. 2E). Here, CD8A is linked to vitiligo.
