What role do cytokines play in immunotherapy?

• A. They provide nutrition to cancer cells
• B. They regulate immune responses and enhance antitumor effects
• C. They increase tumor resistance
• D. They trigger cancer cell apoptosis directly

Answer: (B)

Cytokines play a crucial role in immunotherapy primarily by regulating immune responses and enhancing antitumor effects. They are signaling proteins that are produced by various cells in the body, particularly immune cells, and they help to communicate and coordinate the immune response against cancer. In the context of immunotherapy, cytokines can stimulate the proliferation and activation of immune cells, such as T cells and natural killer (NK) cells, leading to a more effective attack on tumor cells. They can also enhance the ability of these immune cells to recognize and destroy cancer cells, thus improving the overall efficacy of the treatment. Some cytokines, like interleukin-2 (IL-2) and interferons, have been specifically utilized in immunotherapy protocols due to their potent effects on boosting the immune system's ability to fight cancer. In contrast, the other options do not accurately represent the role of cytokines in immunotherapy. While some might argue that cytokines can have various effects on tumor biology, their primary role in this context is to enhance the immune response rather than providing nutrition to cancer cells, increasing tumor resistance, or directly triggering apoptosis in cancer cells.
