Which of the following statements is correct about the production of antibodies after stimulation of B cells by antigen? Multiple Choice a. Later, under the influence of T-helper cells, IgM-secreting plasma cells may stop producing and secreting IgM in favor of another antibody class, usually IgD. b. Pentameric IgM serves as the B-cell receptor for antigen, and monomeric IgM is the first type of antibody secreted after B-cell activation. c. Class switching occurs when a cell secreting IgM changes the...
