WebT-Cell Receptor Excision Circles. TCR excision circles (TREC) are generated during TCR gene rearrangement of thymocytes, and may persist for long periods in T-lineage cells … 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.
