TNFR-1, also known as CD120a, is one of the most important receptors for tumor necrosis factor. It serves as a "master switch" for inflammation and cell death programs, playing a central role in immune defense, tissue homeostasis, and disease development.

TNFR-1， Also known as CD120a or TNFRSF1A, it is a member of the tumor necrosis factor receptor superfamily, primarily responsible for mediating the biological functions of TNF - α. As a type I transmembrane protein widely expressed on various cell surfaces, TNFR-1 plays a central role in key immune processes such as inflammation, cell survival, and programmed cell death.
