Autoimmune diseases are often associated with HLA molecules. Multiple sclerosis (MS) is a prototypical example with the HLA-DR15 haplotype as strongest genetic factor. How it contributes to MS is not clear, but key to understand this and other autoimmune diseases. Autoreactive CD4+ T cells and proin...
Dominant protection from HLA-associated autoimmune disease is conferred by antigen specific regulatory T cells. Susceptibility and protection against human T cell mediated autoimmune diseases, including type I diabetes, multiple sclerosis and Goodpasture’s disease, is associated with particular Huma...
Epstein-Barr virus (EBV) is involved in causing and probably also perpetuating multiple sclerosis (MS). Among several mechanisms, how EBV may contribute, are transcriptome alterations including changes of antigen processing and preferential presentation of both viral and self-antigens. Here, we foun...
HLA-DR15 is a haplotype associated with multiple sclerosis. It contains the two DRB* genes DRB1*1501 (DR2b) and DRB5*0101 (DR2a). The reported anchor motif of the corresponding HLA-DR molecules was determined years ago based on a small number of peptide ligands and binding assays. DR2a could display...
HLA-DR-lacking HSPCs [HLA-DR(-) HSPCs] were detected in aplastic anemia (AA) patients with HLA-DR15. HLA-DR(-) HSPCs may evade the attack by CD4+ T-cells recognizing the autoantigen presented by HLA-DR15. The goal of this study is to clarify the immune escape mechanisms from antigen-specific T-cells...
