Definition Of:

MAJOR HISTOCOMPATIBILITY COMPLEX

Bible DictionaryAids Glossary
a group of genes that control the expression of cell surface protein markers (also known as human leukocyte antigen or HLA markers) that determine receptor shape and allow immune cells to recognize components of the body (i.e., to distinguish "self" from "non-self"). MHC molecules are necessary for antigen presentation and for recognition of antigens by immune system cells. Each individual has one of a variety of genetically-determined MHC/HLA patterns. There are two classes of MHC molecules, MHC-I and MHC-II.
Bible DictionaryGlossary of HIV(AIDS)-Related Terms
Two classes of molecules on cell surfaces. MHC class I molecules exist on all cells, and hold and present foreign antigens<!-- (see) --> to CD8 cytotoxic T lymphocytes<!-- (see) --> if the cell is infected by a virus or other microbe. MHC class II molecules are the billboards of the immune system. Peptides derived from foreign proteins are inserted into MHC's binding groove and displayed on the surface of antigen-presenting cells. These peptides are then recognized by T lymphocytes so that the immune system is alerted to the presence of foreign material. See Histocompatibility Testing.
Bible DictionaryHIV Vaccine Glossary
the gene cluster that controls certain aspects of the immune response. Among the products of these genes are the histocompatibility antigens, such as HLA class I antigens, which are present on every cell with a nucleus and serve as markers to distinguish self from non-self. (See also HLA.)
