Anti-EDB Immunocytokine, scFv (L19)-TNFα (ACFP-SH093)

This antibody-cytokine fusion protein was achieved by conjugating/fusing the Anti-EDB scFv to TNFα. It was expressed in CHO and purified with affinity chromatography. The fusion protein (L19mTNFα) composed of murine TNFα and a high-affinity antibody fragment (L19 ScFv) to the EDB (extra domain B) of fibronectin, a marker of angiogenesis, maintained the trimeric structure of TNFα and showed greater anti-cancer therapeutic activity than murine TNFα in vivo. These data suggest that using antibody to deliver TNFα to tumors may concentrate therapeutically active doses of TNFα in the tumors. This immunocytokine was designed for treating Advanced solid tumors, Advanced pancreatic cancer, Metastatic melanoma.

Cytokines 1 Description
Tumor necrosis factor (TNF, tumor necrosis factor alpha, TNFα, cachexin, or cachectin) is a cell signaling protein (cytokine) involved in systemic inflammation and is one of the cytokines that make up the acute phase reaction. It is produced chiefly by activated macrophages, although it can be produced by many other cell types such as CD4+ lymphocytes, NK cells, neutrophils, mast cells, eosinophils, and neurons. The primary role of TNF is in the regulation of immune cells. TNF, being an endogenous pyrogen, is able to induce fever, apoptotic cell death, cachexia, inflammation and to inhibit tumorigenesis and viral replication and respond to sepsis via IL1 & IL6 producing cells. Dysregulation of TNF production has been implicated in a variety of human diseases including Alzheimer's disease, cancer, major depression, Psoriasis and inflammatory bowel disease (IBD). While still controversial, studies of depression and IBD are currently being linked to TNF levels. Recombinant TNF is used as an immunostimulant under the INN tasonermin. TNF can be produced ectopically in the setting of malignancy and parallels parathyroid hormone both in causing secondary hypercalcemia and in the cancers with which excessive production is associated.
