"We examined major histocompatibility complex (MHC) class II expression in B cells, peripheral blood monocytes, activated T cells, epidermal Langerhans cells, monocyte-derived dendritic cells, dermal microvascular endothelial cells (DMEC) and fibroblasts of twin brothers with MHC class II deficiency. Although residual human leucocyte antigen (HLA)-DR expression was found on a subpopulation of epidermal Langerhans cells and a subset of peripheral blood monocyte-derived dendritic cells, the patients' B cells, monocytes and activated T cells were HLA-DR negative. After treatment with interferon-gamma (IFN-gamma), the patients' DMEC expressed HLA-DR but not -DP and -DQ at the protein and mRNA level, whereas IFN-gamma failed to induce HLA-DR expression on dermal fibroblasts." . .
