ANATOMY

Detailed explanation-1: -A type of immune cell that can kill certain cells, including foreign cells, cancer cells, and cells infected with a virus. Killer 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: -3 Cytotoxic T cells. Cytotoxic T cells are effector cells that destroy virus-infected cells, tumor cells, and tissue grafts that exist in the cytosol, or contiguous nuclear compartment.

Detailed explanation-3: -Cytotoxic T cells kill target cells bearing specific antigen while sparing neighboring uninfected cells. All the cells in a tissue are susceptible to lysis by the cytotoxic proteins of armed effector CD8 T cells, but only infected cells are killed.

Detailed explanation-4: -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-5: -CAR T-cell therapy is a type of treatment in which a patient’s T cells (a type of immune cell) are changed in the laboratory so they will bind to cancer cells and kill them.
