APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -T-lymphocytes or T-cells, do not themselves produce antibodies. They help B-cells in the process of recognition of pathogen proteins. This, in turn, helps B-cells produce antibodies that can recognize and bind to specific proteins produced by the infectious agent.

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: -1) T cells (T lymphocytes) are crucial in the recognition of antigens presented by self-MHC. The T cell progenitors undergo proliferation and differentiation in the thymus and form a mature T cell.
