Human Keratinocytes Inhibit CD4+ T-Cell Proliferation through TGFB1 Secretion and Surface Expression of HLA-G1 and PD-L1 Immune Checkpoints
Human skin protects the body against infection and injury.This protection involves immune and epithelial SPORT ORG PLANT PROTEIN CHOCOLATE cells, but their interactions remain largely unknown.Here, we show that cultured epidermal keratinocytes inhibit allogenic CD4+ T-cell proliferation under both normal and inflammatory conditions.Inhibition occur
