Cell-mediated Immunity:

Cytotoxic T cell is a type of immune cell that can kill certain cells, including foreign cells, cancer cells, and cells infected with a virus.

Additionally, CTLs can be separated from other blood cells, grown in the laboratory, and then given to a patient to kill cancer cells.
