Question

Quizplus · Accepted Answer

Plasma cells are a type of B lymphocyte that play a crucial role in humoral immunity. These cells produce and secrete large amounts of highly specific antibodies, which can bind specifically to a particular antigen. The antibodies produced by plasma cells help to neutralize pathogens by binding to viral proteins or bacterial toxins, marking them for destruction by other immune cells, or causing them to clump together for elimination by phagocytes or the lymphatic system.
