What is one of the primary roles of the immune system's T cells?

The primary role of T cells in the immune system is to recognize and destroy infected or malignant cells. T cells are a type of lymphocyte that plays a critical role in the adaptive immune response. They are equipped with specific receptors that allow them to identify cells that display abnormal signs, such as those infected by viruses or transformed by cancer. Once T cells recognize these compromised cells, they can initiate a direct attack, leading to the elimination of the infected or cancerous cells.

This ability to specifically target and kill harmful cells distinguishes T cells from other components of the immune system. For example, while B cells are responsible for producing antibodies that bind to pathogens, T cells directly engage and destroy cells that pose a threat to the body. Additionally, T cells can also provide help to other immune cells, enhancing the overall immune response, which is critical for fighting infections and cancer.

Other options, while related to immune function, do not encapsulate the principal duty of T cells as accurately. Producing antibodies is primarily a function of B cells, enhancing drug metabolism refers more to the liver and various enzymes than to immune function, and while storing immune memory is relevant to T cells, it is not their primary role. Instead, the immediate action of recognizing and destroying infected
