Diversity and clonal selection in the human T-cell repertoire

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. WebThe specific immune system (in other words, the sum total of all the lymphocytes) can recognize virtually any complex molecule that nature or science has devised. This remarkable ability results from the trillions of different antigen receptors that are produced by the B and T lymphocytes.
