Hla variants
The human leukocyte antigen (HLA) system or complex is a complex of genes on chromosome 6 in humans which encode cell-surface proteins responsible for regulation of the immune system. The HLA system is also known as the human version of the major histocompatibility complex (MHC) found in … See more The proteins encoded by HLAs are those on the outer part of body cells that are (in effect) unique to that person. The immune system uses the HLAs to differentiate self cells and non-self cells. Any cell displaying that person's HLA … See more Studies of humans and animals imply a heterozygous selection mechanism operating on these loci as an explanation for this variability. One proposed mechanism is sexual selection in which females are able to detect males with different HLA … See more In some diseases requiring hematopoietic stem cell transplantation, preimplantation genetic diagnosis may be used to give rise to a sibling with matching HLA, although there are ethical considerations.
