Hla drb1 rheumatoid arthritis

DRB1 is present in all individuals. Allelic variants of DRB1 are hla drb1 rheumatoid arthritis with either none or one of the genes DRB3, DRB4 and DRB5.

Identification of these antigens has led to greater success and longevity in organ transplant. Good matching of these antigens between host and donor are most critical for achieving graft survival. HLA-DR is also involved in several autoimmune conditions, disease susceptibility and disease resistance. HLA-DR molecules are upregulated in response to signalling. DR molecule and presented to a few of a great many T-cell receptors found on T-helper cells. These cells then bind to antigens on the surface of B-cells stimulating B-cell proliferation.
