Question

Quizplus · Accepted Answer

Plasma cells are specialized B lymphocytes that produce and secrete large amounts of antibodies, which are proteins that can recognize and bind to specific antigens. Circulating antibodies play an important role in the immune response by neutralizing or eliminating pathogens or foreign substances. NK cells are involved in innate immunity and can kill infected or abnormal cells. Helper T cells recognize antigens and activate other immune cells, including B cells and cytotoxic T cells. Cytotoxic T cells can directly kill infected or abnormal cells, and suppressor T cells can downregulate the immune response. However, neither of these cell types is responsible for the production of circulating antibodies.
