MHC (major histocompatibility complex)
MHC markers- which are proteins that present or "show" antigens like bacteria to other immune cells. Instead of being targets, they are helper proteins of the immune system.
At the heart of the immune response is the ability to distinguish between 'self' and 'non-self.'Every cell in your body carries the same set of distinctive surface proteins that distinguish you as 'self.' Normally your immune cells do not attack your own body tissues, which all carry the same pattern of self-markers.This set of unique markers on human cells is called the major histocompatibility complex (MHC). There are two classes: MHC Class I proteins, which are on all cells, and MHC Class II proteins, which are only on certain specialized cells.
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.
MHC = major histocompatibility complex What makes up MHC are HLA's (human leukocyte antigens), which there are subclasses for.
MHC IMHC I is present in all cells except red blood cells (they lack nuclei). MHC I will present an intravesicular antigen to the cells surface for it to be identified as self or foreign by your adaptive immunity cells.MHC IIMHC II is present in professional antigen presenting cells which include: macrophages, B cells and dendritic cells. These cells will engulf bacteria, soluble proteins, viruses, etc. Whatever was taken into the cell becomes processed in the increasingly acidic endosome that eventually will cut the antigen into peptides. MHC II transported from the ER will meet up with this endosome and the peptides will bind to MHC II for it to eventually present on the cells surface.
MHC Krylya Sovetov was created in 2008.
All nucleated cells bring pieces of endogenous proteins to the surface to display on the MHC protein.
