Cytokines are small proteins that are produced by various immune and non-immune cells in the body. They play an important role in cell signaling and communication, as well as regulating the immune response to infections, inflammation, and other physiological processes.
The common cytokine classes include:
1. Interleukins (IL): These cytokines are produced by white blood cells (leukocytes) and play a key role in communication between immune cells. Examples include IL-1, IL-2, IL-4, IL-6, and IL-10.
2. Tumor necrosis factor (TNF): TNF is a cytokine that is produced by macrophages and other immune cells in response to infections and inflammation. It plays a key role in the inflammatory response and is involved in the destruction of tumor cells.
3. Chemokines: These cytokines are involved in the migration and localization of immune cells to sites of infection or inflammation. Examples include interleukin-8 (IL-8) and monocyte chemoattractant protein-1 (MCP-1).
4. Interferons (IFNs): These cytokines are produced by infected cells and play an important role in the immune response to viral infections. They help to activate immune cells and increase their ability to attack and destroy infected cells.
5. Transforming growth factor-beta (TGF-β): TGF-β is a cytokine that is involved in a wide range of cellular processes, including cell growth and differentiation, immune regulation, and tissue repair.
