Detailed explanation-1: -Although the secretion of perforin and granzymes is the main way by which cytotoxic CD8 T cells eliminate infection, with the expression of Fas ligand playing a lesser role, most cytotoxic CD8 T cells also release the cytokines IFN-, TNF-, and TNF-, which contribute to host defense in several ways.
Detailed explanation-2: -Once stimulated by the appropriate antigen, helper T cells secrete chemical messengers called cytokines, which stimulate the differentiation of B cells into plasma cells, thereby promoting antibody production.
Detailed explanation-3: -Helper T cells secrete cytokines that help B cells differentiate into plasma cells. These cells also help to activate cytotoxic T cells and macrophages.
Detailed explanation-4: -TH1 cells secrete cytokines to enhance the activities of macrophages and other T cells. TH1 cells activate the action of cyotoxic T cells, as well as macrophages. TH2 cells stimulate naïve B cells to destroy foreign invaders via antibody secretion.
Detailed explanation-5: -T lymphocytes, the major effector cells in cellular immunity, produce cytokines in immune responses to mediate inflammation and regulate other types of immune cells.
