TNF-alpha

TNF-alpha (Tumor Necrosis Factor-alpha) is a protein produced by immune cells that helps regulate inflammation and the body's response to infections or injuries. It plays a key role in signaling the immune system to fight harmful threats, such as bacteria, viruses, or damaged cells. While essential for defense and healing, excessive or inappropriate production of TNF-alpha can contribute to chronic inflammation and autoimmune diseases. Medications that block TNF-alpha are used to treat conditions like rheumatoid arthritis, reducing inflammation and tissue damage. Overall, TNF-alpha is a crucial part of the immune system's communication network.
