What Is Antigen Processing?

Antigen treatment refers to the process in which the adjuvant cells degrade the natural antigen moderately and bind to the molecules of the major histocompatibility complex. Including antigen denaturation, degradation and modification. Depending on the source and nature of the antigen, antigen processing takes two forms: one is the antigen that enters in vitro, such as a bacterial protein or an imported soluble protein, which is first swallowed or swallowed into the antigen-presenting cells, which are in the phagocytic vesicles. After the protease is partially degraded, the degraded fragment is bound to the peptide-binding gap of the n-type MHC molecule in the vesicle, and then expressed on the surface of the antigen-presenting cell for the recognition of n-type MHC restricted T cells. This is called exogenous or Endosome pathway. ^[1]
