There are several types of cytokines, each with a specific role in the immune response:
Interleukins (ILs): These are primarily produced by leukocytes and play a role in the differentiation and proliferation of immune cells. Interferons (IFNs): These are critical in the defense against viral infections and modulate the immune response. Tumor Necrosis Factors (TNFs): These are involved in systemic inflammation and can induce fever, apoptotic cell death, and inflammation. Chemokines: These are involved in chemotaxis, guiding the migration of cells to the site of infection or injury.
