antigen processing involves the breakdown of protein antigens and the subsequent association of peptide fragments on the surface of antigen-presenting cells with MHC class I or class II proteins.
Antigen is any foreign particle or molecule that can trigger a n immune response in the body.
After the body encounters the antigen cells like macrophages, B cells and dendritic cells will recognise and destroy them. The parts of the antigen will be presented by the macrophages to the T cells and hence they are also called Antigen presenting cells.
Antigen presenting cells will showcase the antigen or its part to the T cells. This is done with the help of a protein called major histocompatiblity complex or MHC complex proteins.
MHC proteins are present on cell surface and holds the antigens to showcase them to T cells.
