Tumor necrosis factor

Tumor necrosis factor (TNF, cachexin, or cachectin; often called tumor necrosis factor alpha or TNF-α) is a cytokine – a small protein used by the immune system for cell signaling. If macrophages (certain white blood cells) detect an infection, they release TNF to alert other immune system cells as part of an inflammatory response. TNF is a member of the TNF superfamily, which consists of various transmembrane proteins with a homologous TNF domain.
