Detailed explanation-2: -A type of immune cell that can kill certain cells, including foreign cells, cancer cells, and cells infected with a virus.
Detailed explanation-3: -Killer T-cells or cytotoxic T-cells directly kill cells that have already been infected by a foreign invader.
Detailed explanation-4: -Cytotoxic T cells As more Tc cells are developed during an immune response, they overwhelm the ability of the virus to cause disease. In addition, each Tc cell can kill more than one target cell, making them especially effective.
