The germinal center of a lymphatic nodule contains proliferating B-lymphocytes and macrophages.

Question

Quizplus · Accepted Answer

The germinal center of a lymphatic nodule is an area of a secondary lymphoid organ where B-lymphocytes undergo rapid proliferation, differentiation, and clonal expansion during an immune response to an antigen. Germinal centers are characterized by the presence of densely packed B-cells that are undergoing somatic hypermutation and class-switching, as well as follicular dendritic cells, T-helper cells, and macrophages that provide support and antigen presentation to the B-cells. Therefore, choice A is correct, while choice B is incorrect.
