Quizplus · Accepted Answer

Cytotoxic T cells are responsible for attacking foreign cells or body cells infected with viruses, specifically identifying and killing them. B lymphocytes produce antibodies that help to neutralize and eliminate pathogens, while helper T cells assist in activating and coordinating immune response. Plasma cells are mature B cells that secrete antibodies, and suppressor T cells help to regulate and dampen immune responses.
