Lymphokines

Lymphokines are a category of cytokines, which are signaling proteins secreted by white blood cells, specifically T lymphocytes. They play a crucial role in the immune system's communication network. The term "lymphokine" specifically refers to cytokines produced by lymphocytes, distinguishing them from other types of cytokines produced by different cells. These molecules are involved in a wide array of immune responses, acting as messengers to coordinate the activity of various immune cells.

Key functions of lymphokines include regulating the growth, differentiation, and activation of immune cells, such as other lymphocytes, macrophages, and neutrophils. They can promote inflammation, enhance phagocytosis, and stimulate antibody production. For example, interleukins are a major subclass of lymphokines, with different interleukins performing diverse tasks, from initiating inflammatory responses to suppressing immune activity.

The study of lymphokines has been instrumental in understanding cell-mediated immunity and developing immunotherapies. By understanding how these signaling molecules operate, researchers can better target immune responses in diseases like cancer and autoimmune disorders. Their intricate interplay with other immune mediators makes them a central focus in immunology research.
