Explanation:
Detailed explanation-1: -Primary T cell activation involves the integration of three distinct signals delivered in sequence: (1) anti-gen recognition, (2) costimulation, and (3) cytokine-mediated differentiation and expansion.
Detailed explanation-2: -T cells (also called T lymphocytes) are major components of the adaptive immune system. Their roles include directly killing infected host cells, activating other immune cells, producing cytokines and regulating the immune response.
Detailed explanation-3: -Three main phases encompass the immune response that is orchestrated by antigen-specific T cells: expansion, contraction and memory (see Fig. 1a).
