Question

Quizplus · Accepted Answer

Antigen presentation is necessary for the activation and clonal selection of T cells. The major histocompatibility complex (MHC) molecules present the antigen fragments to T cells, leading to their activation and proliferation. B cells can directly recognize antigens without the need for antigen presentation. Plasma cells are the mature, antibody-producing cells that arise from activated B cells. Antigen-presenting cells (such as dendritic cells, macrophages, and B cells) are responsible for presenting antigens to T cells. Antibodies are produced by plasma cells and do not require antigen presentation for their production.
