One of the characteristic features of the MHC is the large number of alleles at each locus. This polymorphism is apparent in short regions along the polypeptide chains, predominantly within the The presence of these polymorphisms means that different MHC molecules (and each MHC molecule!) can present to T cells. Individuals inherit the linked alleles that encode the MHC proteins as a group called a the same peptides transmembrane region different peptides haplotype peptide binding cleft regulatory region nonclassical complex

Immunology

Immunology is the division of science involved with the immune reactions occurring in living organisms. The organisms are accustomed to evolving internal defense mechanisms to evade the invasion of microbial pathogens. Diverse cells are connected with stimulating the immune responses, which produce inhospitable conditions to the microbes prompting their lysis and thus inhibits the multiplication of the pathogens. The immune system can distinguish the pathogens through the aid of cellular intercommunication and launch responses to destroy them.
