Explanation:
Detailed explanation-1: -Cell-mediated immunity is largely based on the function of T-helper (Th) lymphocytes. These lymphocytes (CD4+; T-helper cells) mediate proliferation and differentiation of various immune-competent cells via their release of various cytokines (e.g., IL-2, IL-4, IL-5, IL-6).
Detailed explanation-2: -A major role of the T cell arm of the immune response is to identify and destroy infected cells. T cells can also recognize peptide fragments of antigens that have been taken up by APC through the process of phagocytosis or pinocytosis.
