Tumor Necrosis Factor (TNF)

Tumor Necrosis Factor (TNF) is a protein produced by immune system cells that helps regulate inflammation and immune responses. It's called "tumor necrosis factor" because it can promote the death of cancer cells and limit tumor growth. TNF also plays a key role in fighting infections by signaling immune cells to respond, but excessive or uncontrolled production can lead to chronic inflammation and tissue damage, contributing to conditions like autoimmune diseases. Understanding TNF helps in developing treatments for diseases involving inflammation and immune regulation.
