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 constant region of its antibody molecules, producing a different antibody class (IgG, IgA, or IgE).

    In humans, IgA is produced in copious amounts, estimated to be a rate of 3 g/day. Nearly all of the IgA secreting plasma cells are found in the gastrointestinal (GI) tract where the secreted IgA is transported across the GI epithelium into the lumen of the gut. There, this antibody protects the GI epithelium against intestinal pathogens. In contrast, none of the GI resident long-lived antibody secreting cells produce antibodies of the IgG class. The differential localization of long-lived antibody...
