WebThe T-cell receptor gene segments rearrange during T-cell development to form complete V-domain exons ().T-cell receptor gene rearrangement takes place in the thymus; the order and regulation of the rearrangements will be dealt with in detail in Chapter 7.Essentially, however, the mechanics of gene rearrangement are similar for B and T cells.The T-cell … WebIn the immune system, effector cells are the relatively short-lived activated cells that defend the body in an immune response. Effector B cells are called plasma cells and secrete antibodies, and activated T cells include cytotoxic T cells and helper T cells, which carry out cell-mediated responses. The production of effector cells in response ...
