Question

Quizplus · Accepted Answer

Natural killer (NK) cells are specialized immune cells that can detect and kill abnormal cells, including foreign cells and those infected with a virus. They do not require prior exposure to a specific antigen and are therefore considered nonspecific in their action. T lymphocytes, reticular cells, dendritic cells, and macrophages are all involved in immune surveillance to some extent, but they are not as specialized in detecting and destroying abnormal cells as NK cells.
