Question

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. Neutrophill 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

Explanation / Answer

1.13 False. As, B cell receptor undergo process of affinity maturation not T cell.

1.14 False. lymphocyte are antigen specific receptors

1.15 Dendritic cells are an important link between innate and adaptive immunity.

1.16 Antibody fight the antigen with the process of neutralization, agglutination, optimization, complement activation but not co stimulation of T cell. Hence, incorrect option is b.

1.17 True, T helper cell does not contain MHC I.
