Question 15 3 pts Null mutations in which of the following would allow antigen receptor production but reduce junctional diversity? Ligase O AID Tdt Rag2 Rag1 Question 16 3 pts What happens to centrocytes that have high-affinity (tightly binding) antigen receptors after somatic hypermutation? They receive survival signals from TFH cells They cannot process antigen or present it to TFH cells They undergo phagocytosis by dendritic cells in the "light zone" They die by apoptosis
Which of the following statements is (are) true of a T cell that expresses two α chains (and thus two different T-cell receptors) as a result of ineffective allelic exclusion of the α chain during rearrangement? There will be two unique TCRs on the surface of this T cell. Engaging either of the T-cell receptors on MHC molecules of the thymic epithelium will result in positive selection. If either T-cell receptor binds strongly to self-peptide presented by self-MHC molecules, the...
