Answer:
T cells provide an immune response against the antigen by attacking infected cells and provide immediate response against future infection, by producing antibodies.
Explanation:
T cells or the T lymphocytes are one of the major components of the acquired immune system. They are important to have an immune response against pathogens.
T cells act against intracellular antigens such as protozoa, viruses, and bacteria (intracellular), and providing help for the antibody response for extracellular pathogens. They are of four main types - CD4+ helper, CD8+ cytotoxic cells, memory T cells, and NK cells.
These cells release cytokines to directly attack infected cells and stimulate the production of more T cells. Some of these T cells will become memory T cells in preparation for secondary infections, and others become cytotoxic T cells to attack infected cells.
