Specificity

This antibody neutralizes Hu rTNFa mediated cytotoxicity of L929 cells and inhibits tumor growth in mice. It protects mice against toxicity of HurTNFa. Tumor Necrosis Factor Alpha (TNF-alpha) is a protein secreted by lipopolysaccharide-stimulated macrophages, and causes tumor necrosis when injected into tumor bearing mice. TNF-alpha is believed to mediate pathogenic shock and tissue injury associated with endotoxemia. TNF-alpha exists as a multimer of two, three, or five non-covalently linked units, but shows a single 17kDa band following SDS PAGE under non-reducing conditions. TNF-alpha is closely related to the 25kDa protein Tumor Necrosis Factor beta (lymphotoxin), sharing the same receptors and cellular actions. TNF-alpha causes cytolysis of certain transformed cells, being synergistic with interferon gamma in its cytotoxicity. Although it has little effect on many cultured normal human cells, TNF-alpha appears to be directly toxic to vascular endothelial cells. Other actions of TNF-alpha include stimulating growth of human fibroblasts and other cell lines, activating polymorphonuclear neutrophils and osteoclasts, and induction of interleukin 1, prostaglandin E2 and collagenase production.

Background: TNF-alpha

Tumor necrosis factor (TNF)-alpha is a pro-inflammatory cytokine belonging to the TNF superfamily that is secreted by monocytes/macrophages, T cell, and natural killer (NK), among others (1). TNF-alpha is synthesized as a 233 amino acid (aa) transmembrane protein (mTNF-alpha) with a theoretical molecular weight (MW) of 26 kDa (1,2) that forms a homotrimer. mTNF-alpha is cleaved by TNF-alpha converting enzyme (TACE) and released in its 157 aa, 17 kDa soluble form (sTNF-alpha) (1-5). Both mTNF-alpha and sTNF-alpha are capable of binding type 1 TNF receptors (TNFR1), whereas mTNF-alpha predominately binds to TNFR2 (1,2). TNF-alpha binding to its receptors causes receptor recruitment of adaptor proteins, formation of signaling complexes, and downstream signaling cascades (e.g. MAPK, NF-kappaB, and Caspase-8), leading to distinct cellular responses such as survival, proliferation, inflammation, necroptosis, and apoptosis (1-5).

TNF-alpha is critical for normal immune response; however, dysregulation of TNF-alpha production can result in various pathologies (2,4,5). Excessive production of pro-inflammatory cytokines including interleukin 1 (IL-1), IL-6, and TNF-alpha has been implicated in an array of autoimmune diseases like rheumatoid arthritis (RA), inflammatory bowel disease (IBD), and psoriasis (2,4,5). Anti-TNF monoclonal antibodies, including Infliximab, and soluble TNFR have been approved for the treatment of autoimmune and TNF-mediated diseases (5). Additionally, data suggests that TNF inhibitors can be beneficial for treating patients experiencing immune-related adverse events associated with immune checkpoint inhibitor cancer treatment (6).
