Detailed explanation-1: -Cytotoxic T cells kill infected cells, whereas helper T cells help activate macrophages, B cells, and cytotoxic T cells. Effector helper T cells secrete a variety of signal proteins called cytokines, which act as local mediators.
Detailed explanation-2: -Cytokine Secretion The first method cytotoxic T cells use to fight infection is the secretion of cytokines. Cytokines are substances that activate other cells. Cytotoxic T cells release two cytokines in particular, TNF-alpha and IFN-gamma, which facilitate the activation of macrophages.
Detailed explanation-3: -Cytotoxic T lymphocytes (CTLs) represent one of several types of cells of the immune system that have the capacity to directly kill other cells. They play a major role in host defense against viral infection, as well as infection by other intracellular pathogens that replicate in the cytoplasm of the host cell.
