In contrast, negative control xenotransplants injected with PBMCs/PHA showed normal anagen HFs and a significantly lower expression of HLA-A,B,C, β2 MG, and HLA-DR, paired with the expected normal expression levels α-MSH and TGF-β1 protein (Figure 7E) as assessed by qIHM (Figure 7F). The gene discussed is HLA-A; the disease is Hand-foot syndrome.
