Giant nanomachine aids the immune system
Cells that are infected by a virus or carry a carcinogenic mutation, for example, produce proteins foreign to the body. Antigenic peptides resulting from the degradation of these exogenous proteins inside the cell are loaded by the peptide-loading complex onto so-called major histocompatibility complex molecules (MHC for short) and presented on the cell surface. There, they are specifically identified by T-killer cells, which ultimately leads to the elimination of the infected cells. This is how our immune system defends us against pathogens.
