Kinda like THC in weed. Just MHC in meth.
Peptides
Because it is more likely that a relative will have the same MHCs (major histocompatibility complexes) on their cells. When immune cells patrol the body they will bind these complexes which tell them whether the cell they are binding is 'self" or "nonself". If they bind a MHC which they percieve as nonself, they may initate an immune response leading to rejection of the graft
MHC = major histocompatibility complex What makes up MHC are HLA's (human leukocyte antigens), which there are subclasses for.
MHC Krylya Sovetov was created in 2008.
MHC I and MHC II are always expressed. The antigen it presents on a cells surface can be foreign or it can be self. It is the T cell that determines whether what the MHC is displaying is self or not. Remember antigen can be protein, lipid, sugars, etc.
All cells with a nuclei have MHC class 1.
MHC molecules are located in the short arm of chromosome 6.
MHC is to present on a cell's surface for your T cells and antibodies to determine if it is self or foreign.
The advantage of having a highly polymorphic MHC is that it adds to variety of which it can bind to a peptide. If MHC cannot bind to a viral or bacterial peptide then your body cannot use its' adaptive immunity to fight off an infection. The T cell requires MHC to activate and if MHC is not binding to anything because it has such a small repertoire of alleles to create a MHC molecule, it will render T cells useless. So to have a highly polymorphic MHC gene that can encode to bind to many different peptides is advantageous for survival.
Yes they do. MHC 1 are expressed by all nucleated calls (except neurones) and platelets. MHC 11 are expressed by B-cells, macrophages and dendtitic cells. Therefore, some cells express both types.
The answer previously here about MHC referring to mice and HLA referring to humans is catagorically untrue! HLA and MHC are in fact the same, so HLA class 1 = MHC class 1. Same goes for class 2.
Peptides
MHC is an acronym for "major histocompatibility complex." If one desires to find out more about the MHC genetic issue, one might find reliable information on the government NIH website.
MHC proteins express antigens on a cell surface for T cells to identify whether the antigens presented are self or foreign. There are two classes MHC I and MHC II. They differ in which cells they require to activate depending on the pathogen present.
