Detailed explanation-1: -Helper T cells may be as important as cytotoxic T cells in the immune response to a virus infection. Helper T cells are required for the generation of cytotoxic T cells and for optimal antibody production.
Detailed explanation-2: -Phagocytes engulf the intruders, break them down and chew them up. Lymphocytes are further broken down into two more types. The B lymphocytes (or B-cells) create antibodies and alert the T lymphocytes (or T-cells) to kill the pathogens.
Detailed explanation-3: -The two major divisions of adaptive immunity, antibody and T-cell-mediated, are mainly directed at different targets. Antibodies usually function by binding to free viral particles, and in so doing block infection of the host cell. In contrast, T cells act principally by recognizing and destroying virus-infected cells.
Detailed explanation-4: -Primary control of viral infection is exerted by immune responses.
