Question

Quizplus · Accepted Answer

Natural killer cells are cells involved in innate immunity that play an important role in recognizing and destroying cancer cells. Their absence increases the chance of developing malignant tumors. Other cells involved in innate immunity such as macrophages and dendritic cells also have the ability to recognize and eliminate cancer cells. However, the absence of natural killer cells has been shown to have a more profound effect on the development of tumors. Cytotoxic T cells and B cells are involved in adaptive immunity and are not typically considered part of innate immunity. Helper T cells are also involved in adaptive immunity and do not directly recognize or eliminate cancer cells.
