Question

Quizplus · Accepted Answer

Natural killer cells have the ability to recognize and destroy tumor cells without prior stimulation by tumor antigens, making them a crucial part of the immune response against cancer. Cytotoxic T lymphocytes also have this ability, but they require prior activation by recognition of specific tumor antigens presented by MHC molecules. B and D lymphocytes are not typically involved in the direct destruction of tumor cells.
