Document Summary
Adaptive immune system have a conserved region and a variable region. Variable region can adapt we have bcr and tcr: explain tcrs. T cell receptors will recognize and mhc peptide complex. They are very small peptides; 8-12 amino acids. Mhc allele and one peptide: explain bcrs. B cell receptors are composed of poly peptide chains that are held together by disulfide bonds. Each arm consists of 4 heavy chains and 2 light chains. There are two types of light chains; kappa and lamba. There are more types of heavy chains which include: alpha, gamma, delta, elipson, and miuex. Depending on the type of heavy chain = type of antibody used. All are immunoglobin types: discuss the structure of the bcr. Heavy chains lower region is a constant region; does not change; all molecule types will be the same. The heavy/light combination at the top is the variable region that adapts to different pathogens.
