Mhc protein anitgen producing cell
WebbOperation Abstract T cells use the alpha/beta T cell receptor (TCR) to recognize antigenic peptides presented by class I major histocompatibility complex proteins (pMHCs) on the surfaces of antigen presenting cells. Flexibility in both TCRs and peptides plays an important role in antigen recognition and discrimination. WebbAlloreactive T-cell responses directed against minor histocompatibility (H) antigens, which arise from diverse genetic disparities between donor and recipient outside the MHC, are an important cause of rejection of MHC-matched grafts.
