Cytokines primarily function by binding to specific cell surface receptors to activate a cascade of intracellular signaling. This leads to cellular responses in biological processes such as in infection, inflammation, apoptosis, cancer, and development. Cytokines are notable for their roles in autoimmune disorders, characterized by abnormally high proinflammatory activities. Thus there is a considerable interest in cytokine inhibitors and immunosuppressive drugs. Such inhibitors include receptor antagonists, soluble receptors, and cytokine-binding proteins. To find specific inhibitors, type in the desired cytokine target and select desired filters.
