Hello, extremely sorry for the late reply!!
This is what I know so far:
Firstly, each cell displays each own unique marker on its surface (antigens)
MHC codes for a group of proteins that are found on the surface of cells and these group of proteins are able to differentiate between non-self and self antigens.
If a pathogen comes along, bearing non-self antigens (antigens that doesn't come from the body), then the MHC proteins on a cell (any cell?) will then identify this as foreign as it wont be able to recognize the surface antigens on the cell; thus initiating an immune response.
If a substance comes along bearing self antigens (antigens that comes from the body) then the MHC proteins on a cell (any cell?) will be able to identify this as non-foreign as it will be able to recognize the surface antigens on the cell
Purpose of MHC= to differentiate between non-self and self anitgens
Nature of MHC= found on all cells?
*there are two types of MHC
- class 1 and class 2
Appreciate any help
