Quizplus · Accepted Answer

Natural killer cells are large granular lymphocytes that play a key role in innate immunity by directly killing virus-infected cells and tumour cells. They can recognize and kill tumour cells without prior exposure or activation, making them an important component of the body's initial line of defence against cancer. Cytotoxic T cells and B cells are part of the adaptive immune response, while macrophages primarily engulf and digest bacterial cells and debris.
