tumor necrosis factor receptor (TNFR)

Tumor necrosis factor receptor (TNFR) is a type of protein found on the surface of certain cells in the body. It acts like a communicator, receiving signals from a molecule called tumor necrosis factor (TNF). When TNF binds to TNFR, it triggers a chain of responses inside the cell that can lead to inflammation, immune activation, or cell death. These processes are important for fighting infections and managing inflammation, but they must be carefully controlled to prevent diseases like autoimmune disorders. In short, TNFR helps regulate immune responses and cell survival by serving as a key communication point.
