question 1

Multiple Choice

Which one of the following statements accurately describes antigen recognition events in a lymph node during a helper T cell-dependent antibody response to a protein antigen?

• A)Naive B cells and naive T cells simultaneously recognize the intact protein antigen.
• B)Naive B cells recognize intact proteins,generate peptide fragments of these proteins,and present them in complexes with major histocompatibility complex (MHC)molecules to naive helper T cells.
• C)Naive B cells recognize intact proteins,generate peptide fragments of these proteins,and present them in complexes with MHC molecules to differentiated helper T cells.
• D)Naive T cells recognize peptides bound to MHC molecules presented by dendritic cells,and naive B cells recognize the intact protein antigen bound to the surface of follicular dendritic cells.
• E)Differentiated helper T cells recognize peptides bound to MHC molecules on dendritic cells,and the T cells secrete cytokines that promote antibody production by any nearby B cells that have recognized different protein antigens.
