(B) HF dystrophy and perifollicular lymphocytic infiltrates around anagen hair follicles (HFs) (H&E staining) combined with strong expression of (C) HLA-A,B,C, β2 MG, HLA-DR, and downregulation of α-MSH and TGF-β1 in the ILC1lc and in (D) enriched CD8/NKG2D cells versus xenotransplants treated with (E) PBMCs/PHA (IHC staining) (F) quantitative data. Here, HLA-A is linked to hydrops fetalis.
