Web14 de out. de 2024 · The T cell receptor for antigen (TCR; on most T cells, a dimer of an α and a β chain associated with invariant signaling subunits) binds both peptide and MHC determinants ( 1 – 3 ). Accordingly, for any given T cell, the TCR specificity is determined by both the antigenic peptide and the particular MHC molecule the peptide binds. Complementarity-determining regions (CDRs) are part of the variable chains in immunoglobulins (antibodies) and T cell receptors, generated by B-cells and T-cells respectively, where these molecules bind to their specific antigen. A set of CDRs constitutes a paratope. As the most variable parts of the molecules, CDRs are crucial to the diversity of antigen specificities generated by lymphocytes.
