	Histocompatibility (Site not responding. Last check: 2007-09-15)
		The Major Histocompatibility Complex (MHC) is a set of molecules displayed on cell surfaces that are responsible for lymphocyte recognition and "antigen presentation".
		The MHC molecules control the immune response through recognition of "self" and "non-self" and, consequently, serve as targets in transplantation rejection.
		The major histocompatibility complex is encoded by several genes located on human chromosome 6.

	Major histocompatibility complex (Site not responding. Last check: 2007-09-15)
		The major histocompatibility complex ('''MHC''') is a large genomic region or gene family found in most vertebrates containing many genes with important immune system roles.
		To disambiguate the usage, some of the biomedical literature uses Mhc to refer specifically to the HLA protein molecules and reserves MHC for the region of the genome that encodes for this molecule, however this convention is not consistently adhered to.
		MHC gene families are found in essentially all vertebrates, though the gene composition and genomic arrangement varies widely.

	THE MAJOR HISTOCOMPATIBILITY COMPLEX
		MHC class II molecules are constitutively expressed only by certain cells involved in immune responses, though they can be induced on a wider variety of cells.
		All MHC loci are expressed co-dominantly, that is to say both the set of alleles inherited from one's father and the set inherited from one's mother are expressed on each cell.
		Thus the biological role of MHC proteins is to bind small peptides and to "present" these at the cell surface for the inspection of T cell antigen receptors.

	MAJOR HISTOCOMPATIBILITY COMPLEX
		MHC class II molecules comprise two non-identical peptides (alpha and beta) which are non-covalently associated and traverse the plasma membrane with the N terminus to the outside of the cell.
		Thus, as for class I MHC, the genetic polymorphism determines the chemical structure of the groove and influences the specificity and affinity of peptide binding and T cell recognition.
		MHC class I molecule is in dark blue, the associated beta 2 microglobulin in light blue.

		The Major Histocompatibility Complex (MHC) is a group of genes that, in humans, code for a complex of cell surface proteins called the Human Leukocyte Antigen (HLA).
		The MHC class I binds to a type of immune system cell called a killer (cytotoxic) T cell and "presents" the captured antigen to it.
		MHC class III proteins are a diverse group of molecules that perform a variety of functions in the body.

	Major Histocompatibility Complex Information on Healthline
		This specialized type of immunity is usually needed to eliminate an infection and is dependent on the role of the proteins of the major histocompatibility complex.
		The major players in acquired immunity are the antigen-presenting cells (APCs), B-cells, their secreted antibodies, and the T-cells.
		Related to this role in disease immunity, MHC is also important in organ and tissue transplantation, as well as playing a role in susceptibility to certain diseases.

	Structure and Function of the major histocompatibility complex (MHC) proteins.
		The MHC Class II proteins (found only on B lymphocytes, macrophages, and other cells that present antigens to T cells), which primarily present peptides which have been digested from external sources, are needed for T-cell communication with B-cells and macrophages.
		The MHC proteins, and several closely associated with them in the carrying out of their functions, are coded for by loci that are close together within the Human Genome.
		Major Histocompatibility Complex proteins and their associated molecules are fundamental in the process of antigen presentation.

		Part of the proteins encoded by the MHC are the proteins on the outer part of body cells that are (effectively) unique to that person.

		Schematic representation of MHC class II MHC Class II molecules are found only on a few specialized cell types, including macrophages, dendritic cells, activated T cells, and B cells, all of which are professional antigen-presenting cells (APCs).

		The MHC controls many activities of the immune cells, including the transplantation rejection process and the killing of virus-infected cells by specific killer T lymphocytes.
		In addition to being critical in the marrow transplant process, the MHC has a large number and variety of disease associations, and thus the scope of this advance would have the potential for a broad impact on human health.

		Class I and class II MHC proteins (also referred to as MHC molecules) are critical to the function of the immune system.
		Class II MHC proteins, encoded in the region of the chromosome for HLA-D, differ from Class I molecules in their presentation of peptides in the binding groove by allowing access to the ends of the peptide.
		Class I MHC molecules present to killer T Cells, whereas Class II MHC molecules present to helper T Cells, and are found only on immune system cells.
