  MHC
MHC was established in May 1993 by Managing Director, Roger Coggan, and the original business emphasis was to supply professional IT specialist resource on a contract basis to local organizations.
From 1997 to 1999, MHC became heavily involved in facilitating IT resource, both on a permanent and contract basis, to ensure that local and national companies were able to detect and resolve their Year 2000 systems issues.
MHC has applied this experience and service ethic to the local and national market and is now supporting clients of all sizes and technologies, and has maintained a healthy financial standing.

 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.

 PhD position: Evolution of major histocompatibility complex (MHC) polymorphisms
Genes of the MHC are the most polymorphic loci known for vertebrates, and the proposed selection pressures for the MHC polymorphism range from inbreeding avoidance, heterozygote advantage, to host-pathogen co-evolution.
The obtained polymorphism is therefore not stable, i.e., the frequencies of MHC alleles fluctuate, and by a ``Red Queen evolution'' novel alleles tend to replace established alleles.
Thus MHC molecules play a key role in vertebrate immune responses, and are responsible for heterogeneities between individuals in the immunity to infection, allergens and self-antigens.

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 Class I and Class II MHC molecules belong to a group of molecules known as the Immunoglobulin Supergene Family, which includes immunoglobulins, T-cell receptors, CD4, CD8, and others.

 Invitrogen - Molecular Probes - Note 7.3 - Technical Focus: MHC Tetramer Technology
MHC molecules act in a dual role; their amino-terminal domains bind antigen for presentation to T cells, as well as serving as a marker identifying host cells to the immune system.
MHC tetramers are formed by first refolding MHCs in the presence of high concentrations of the desired antigenic peptide, followed by biotinylation of the carboxy-terminus of one chain of the MHC molecule.
It is crucial for MHC tetramer–based assays that the labeled streptavidin be free of unlabeled streptavidin because this lowers the apparent activity of the MHC complex by "blocking" the biotinylation site from binding to the labeled streptavidin.

 MHC Immune Puzzle Solved
Cambridge, MA (Nov. 14 1996) The long-awaited description of the three-dimensional structure of the complex between the human T-cell receptor and the antigenic peptide as linked to a major histocompatibility complex molecule should provide new understanding of how specific immunity is achieved and regulated.
The research indicates that the antigenic peptide produced by degradation of the invading virus within the cell is held within the MHC binding cleft almost like a hot-dog is held in a bun.
The work showed that by bringing the MHC and TCR together directly, regardless of the peptide bound to the MHC, the superantigen circumvents the normal mechanism for T-cell activation by specific peptide-MHC complexes, and triggers a more general reaction instead.

 BioMed Central | Full text | The MHC and Polymorphism of MHC Molecules
The MHC genes are traditionally divided into three classes: the MHC class I and class II genes, which encode the antigen-presenting MHC molecules; and the class III genes, a miscellany of genes encoding some molecules with important immune functions and others with no known immune function (see Figure 4-6).
The non-classical MHC class I molecules are more numerous and more diverse, and some are important in activating specialized classes of T cells; they are described in section 4-5, and their functions are discussed in Chapter 8.
Thus the evolution of diversity in peptide binding is driven by the diversity and mutability of the infectious agents that threaten the survival of animals.

 MHC Evolution [M.Tevfik Dorak]
There is clearly an MHC in amphibians and birds with many characteristics like the MHC of mammals (a single genetic region encoding polymorphic class I and class II molecules) and evidence for polymorphic class I and class II molecules in reptiles.
It would be enlightening to understand both the mechanisms for the regulation of the MHC molecules during ontogeny and the consequences for the immune system and survival of the animals.
Thus, as the most polymorphic system, the MHC contributes to the genetic identity of an individual at the highest resolution and this is expressed as chemosensory identity.

 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.
Class II MHC proteins presenting antigens are detected by a different group of T cells (called T-helper or TH cells) to Class I MHC proteins (which are detected by CTLs cells).
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.
