Question

Quizplus · Accepted Answer

CD8 cells are T cytotoxic cells, also known as killer T cells, which are responsible for recognizing and killing infected or abnormal cells in the body. T helper cells (A) are a separate type of T cell that help activate and direct the immune response, while natural killer cells (B) are a distinct type of immune cell that can also recognize and kill abnormal cells but do not require prior activation like T cells. Macrophages (D) are immune cells that engulf and digest foreign substances and dead cells, but they do not play a direct role in killing infected or abnormal cells like CD8 T cells.
