HLA region of Chromosome 6. The human leukocyte antigen (HLA) system is a complex of genes on chromosome 6 in humans that encode cell-surface proteins responsible for regulation of the immune system. [1] The HLA system is also known as the human version of the major histocompatibility complex (MHC) found in many animals. [2]
HLA research didn't heat up until the 1980s when a group of researchers finally elucidated the shape of the HLA-A*02 protein (just one of many specific HLA proteins). [1] Even more recently, in 2010, the WHO committee responsible for naming all HLA proteins revised their standards for naming to introduce more clarity and specificity in the ...
HLA-A is a group of human leukocyte antigens (HLA) that are encoded by the HLA-A locus, which is located at human chromosome 6p21.3. [1] HLA is a major histocompatibility complex (MHC) antigen specific to humans. HLA-A is one of three major types of human MHC class I transmembrane proteins. The others are HLA-B and HLA-C. [2]

In the bottom half of the diagram, an HLA antibody that did not match the cell's HLA type was added, so there was no complement activation, and no cell lysis occurred. One of the first methods of tissue typing was through serological typing. In this technique, a donor's blood cells are HLA typed by mixing them with serum containing anti-HLA ...
HLA-G histocompatibility antigen, class I, G, also known as human leukocyte antigen G (HLA-G), is a protein that in humans is encoded by the HLA-G gene. [5] HLA-G belongs to the HLA nonclassical class I heavy chain paralogues. Classical HLA I proteins are found on all nucleated cells and express peptides in their peptide binding groove. They ...
A panel-reactive antibody (PRA) is a group of antibodies in a test serum that are reactive against any of several known specific antigens in a panel of test leukocytes or purified HLA antigens from cells. It is an immunologic metric routinely performed by clinical laboratories on the blood of people awaiting organ transplantation. [1]
HLA-A26 (A26) is a human leukocyte antigen serotype within HLA-A serotype group. The serotype is determined by the antibody recognition of α 26 subset of HLA-A α-chains. For A26, the alpha "A" chain are encoded by the HLA-A *26 allele group and the β-chain are encoded by B2M locus. [1] This group currently is dominated by A*2601.
