Which option best describes the nature of IL-2?

Question

Quizplus · Accepted Answer

IL-2 (Interleukin-2) is a cytokine that plays a key role in activating T helper cells, which are essential for the adaptive immune response. It is produced by activated T cells and helps to stimulate the proliferation and differentiation of T cells, B cells, and NK cells. IL-2 is therefore an important cytokine in the regulation of immune responses in the body. Option B is incorrect as IL-2 is not made by macrophages. Option C is partially correct as IL-2 is involved in the lysis of tumor cells, but this is not the main function of this cytokine. Option D is incorrect as IL-2 generally upregulates, rather than downregulates, immune responses.
