TNF-Alpha, or Tumor Necrosis Factor Alpha, is a protein produced by the immune system that plays a crucial role in inflammation and immune responses. It helps regulate various cellular functions, including cell survival, proliferation, and differentiation. Elevated levels of TNF-Alpha are often associated with autoimmune diseases, such as rheumatoid arthritis and Crohn's disease. In addition to its role in inflammation, TNF-Alpha is involved in the body's response to infections and can influence the development of certain cancers. Researchers study TNF-Alpha to better understand its functions and to develop targeted therapies for conditions linked to its dysregulation.
