In cancer immunotherapy, what is the primary function of cytokines?

• A. To encourage cancer cell reproduction
• B. To help repair healthy tissues damaged by therapy
• C. To regulate immune responses and improve tumor targeting
• D. To directly kill cancer cells

Answer: (C)

Cytokines play a crucial role in the immune system by acting as signaling molecules that facilitate communication between immune cells. In the context of cancer immunotherapy, their primary function is to regulate immune responses, which can enhance the body’s ability to target and destroy tumor cells. By modulating the activity of various immune cells, such as T cells and natural killer cells, cytokines can boost the overall immune response, making it more effective at identifying and attacking cancerous cells. When considering the purpose of cytokines in cancer therapy, it is important to understand that they do not directly kill cancer cells themselves; rather, they create an environment that allows other components of the immune system to perform the task of locating and eliminating the tumor. This regulatory function is vital for achieving a targeted response against cancerous cells while minimizing damage to healthy tissue. The other options do not accurately reflect the primary role of cytokines in the context of immunotherapy. While certain cytokines might indirectly assist in the repair of healthy tissues or play roles in other biological processes, their main function within immunotherapy is indeed focused on enhancing immune regulation and improving tumor targeting.
