Human leukocyte antigen (HLA) B27 (subtypes B*2701-2759) [1] is a class I surface molecule encoded by the B locus in the major histocompatibility complex (MHC) on chromosome 6 and presents antigenic peptides (derived from self and non-self antigens) to T cells.
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-B is part of a family of genes called the human leukocyte antigen (HLA) complex. The HLA complex helps the immune system distinguish the body's own proteins from proteins made by foreign invaders such as viruses and bacteria. HLA is the human version of the major histocompatibility complex (MHC), a
In the case of B44, the antigen had already been split from the B12 broad antigen group. In 1983, the cDNA sequences of HLA-A3 and Cw3 [20] All three sequences compared well with mouse MHC class I antigens. The Western European HLA-B7 antigen had been sequenced (although the first sequence had errors and was replaced). In short order, many HLA ...
More than 90% of people affected in the UK have a specific human leukocyte antigen known as the HLA-B27 antigen. [7] The underlying mechanism is believed to be autoimmune or autoinflammatory. [8] Diagnosis is based on symptoms with support from medical imaging and blood tests. [2]
As cases of the HMPV virus continue to increase in the U.S. and in China, here's what you need to know about the virus.
Human MHC class I and II are also called human leukocyte antigen (HLA). To clarify the usage, some of the biomedical literature uses HLA to refer specifically to the HLA protein molecules and reserves MHC for the region of the genome that encodes for this molecule, but this is not a consistent convention.
