Final answer:
Cytotoxic T cells destroy infected cells via apoptosis, plasma cells produce antibodies, and helper T cells release interleukins and cytokines to stimulate other cells.
Step-by-step explanation:
Cytotoxic T cells, also known as killer T cells, are a type of T cell that destroys cells infected with pathogens or cancerous cells. They do this by inducing apoptosis, which is a controlled cell death process. Cytotoxic T cells release perforin and granzymes to destroy infected cells.
Plasma cells are a type of effector cell that is derived from activated B cells. They produce and release antibodies, which bind to specific antigens on pathogens or infected cells. The antibody-antigen complexes can lead to the destruction of the cells.
Helper T cells, also known as T-helper cells, release interleukins and cytokines to stimulate other immune cells. They play a crucial role in managing immune responses and coordinating the actions of different types of leukocytes.
