IL6 and folliculitis: The allograft rejection score, calculated as a combination of the severity of the vasculitis, folliculitis, dermal inflammation, and epidermal degeneration of the allograft, revealed less rejection of the skin allografts transplanted with GelMA/anti-IL-6 in comparison to those transplanted with GelMA (GelMA versus GelMA/anti-IL-6, 14.5 ± 0.9 versus 10.2 ± 1.4, *p < 0.05, n = 4 mice/group) (Fig. 3C).
