IMMUNOLOGY

Detailed explanation-1: -Cytotoxic T-cells play a role in cell-mediated immunity, a type of adaptive immunity. Innate immunity is the immunity already present in your body. You develop adaptive immunity when you’re exposed to infections or other foreign substances.

Detailed explanation-2: -Cytotoxic T cells can be separated from other blood cells, grown in the laboratory, and then given to a patient to kill cancer cells. A cytotoxic T cell is a type of white blood cell and a type of lymphocyte. Also called cytotoxic T lymphocyte and killer T cell.

Detailed explanation-3: -Cytotoxic cells are involved in the direct killing of intracellular pathogens, and the elimination of mutated and cancerous cells. These immune responses are generated by T cells when they recognize an antigen, which is presented to them by antigen-presenting cells.

Detailed explanation-4: -T cells regulate the activities cells participating in immune responses. They provide help for antibody production by B cells, and they are also the effectors of antigen-specific cell-mediated immunity (CMI).
