Alternate Names:  TNFSF2, Cachectin, DIF, Necrosin, Cytotoxin, Cachexin, TNF               Accession Number: P16599
Description:  Tumor necrosis factor alpha (TNF-α) is an inflammatory cytokine secreted by macrophages, monocytes, neutrophils, T cells, and NK-cells following stimulation by bacterial lipopolysaccharide (LPS). TNF-α signal activation occurs through two receptors, TNFR1 and TNFR2. TNFR1 is expressed on most cell types, unlike TNFR2, which is expressed mainly on immune cells. TNF-α functions to stimulate phagocytosis in macrophages, chemoattract neutrophils, increase insulin resistance, and induce fever.
