[IMMUNOLOGY] In comparing the B and T cell receptors, which of the following statements is FALSE? Select one: a. B and T cell receptors do not interact with each other when bound to an epitope b. The T cell receptor binds to epitopes presented on MHC class I or II molecules depending on the type of T cell. The B cell receptor binds to a specific epitope presented by the antigen c. B and T cell receptors recognize epitopes on an individual microbial invader. Activation of both is required for the humoral immune responses to respond to pathogenic challenge d. B and T cell receptors comprise 4 separate polypeptides comprising conserved and variable regions and are bound to the lymphocyte cell surface e. All of the answers are correct

1.13 True or False: Both T-cell and B-cell receptors undergo the process of affinity maturation in order to acquire progressively higher affinity for an antigen during an immune response. 1.14 True or False: Each lymphocyte carries cell-surface receptors with multiple antigen specificity. 1.15 Multiple Choice: Which cell type forms an important link between the innate immune response and the adaptive immune response? A. Dendritic cell B. Neutrophil C. B cell D. Innate lymphoid cell (ILC) 1.16 Multiple Choice: Which of the following options is not a mechanism by which an antibody can protect against a pathogen? A. Neutralization B. Co-stimulation of T cells C. Opsonization D. Complement activation/deposition 1.17 True or False: TH2 cells do not possess MHC class I molecules.
Adi S.
Which of the following is false concerning B or T cells? A. CD8+ cells recognize peptides presented by MHC I on all nucleated cells. B. TCRs recognize 3D structural antigens or epitopes. C. CD4+ cells recognize peptides presented by MHC II on APCs. D. BCRs are membrane-bound versions of the specific antibody (generally IgD) the B cell is programmed to make. E. Potentially multi-billions of BCRs can be generated by RAG gene rearrangements, random point mutations, deletions, and insertions.
