PATHOLOGY

Detailed explanation-1: -A type of immune cell that can kill certain cells, including foreign cells, cancer cells, and cells infected with a virus. Cytotoxic T cells can be separated from other blood cells, grown in the laboratory, and then given to a patient to kill cancer cells.

Detailed explanation-2: -Abstract. The functions of, and interactions between, the innate and adaptive immune systems are vital for anticancer immunity. Cytotoxic T cells expressing cell-surface CD8 are the most powerful effectors in the anticancer immune response and form the backbone of current successful cancer immunotherapies.

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.
