Company Profile:
The National Cancer Institute (NCI) is part of the National Institutes of Health (NIH), which is one of 11 agencies that compose the Department of Health and Human Services (HHS). The NCI, established under the National Cancer Institute Act of 1937, is the Federal Government's principal agency for ...
A recombinant protein consisting of the hu14. 18 monoclonal antibody fused to the cytokine interleukin-2 (IL2) with potential antineoplastic activity. The monoclonal antibody portion of the hu14. 18-IL2 fusion protein binds to tumor cells expressing the GD2 antigen (melanoma, neuroblastoma and certain other tumors); the Fc component of the fusion protein antibody moiety and natural killer (NK) cells mediate antibody-dependent cell-mediated cytotoxicity (ADCC) and complement-dependent cellular cytotoxicity (CDCC) towards GD2-expressing tumor cells. The localized IL2 moiety of the fusion protein stimulates NK and T-cell antitumor cellular immune responses.

A recombinant protein similar or identical to human mannan-binding lectin (MBL) with opsonin activity. MBL, a soluble pattern recognition receptor (PRR) collectin in the C-type lectin superfamily, is a plasma protein that plays an important role in innate immunity; MBL contains a carbohydrate recognition domain at one end and a collagen-like stalk domain at the other. Upon MBL binding to mannose residues on mannose-containing polysaccharides (mannans) on the surfaces of a microorganisms, activation of the complement system results in the deposition of complement components (opsonization) and the clearance of the opsonized microorganisms by phagocytic cells. MBL is part of the mannan-binding lectin pathway (also known as the Ali/Krueger pathway), which has similarities to the classical complement pathway in that activation of C4 and C2 produce activated complement proteins further down the complement cascade. However, unlike the classical complement pathway, activation of this pathway is not antibody dependent.

A recombinant protein similar or identical to human mannose-binding lectin (MBL) with antimicrobial activity. MBL is a plasma protein containing a carbohydrate recognition domain at one end and a collagen-like stalk domain at the other. The presence of multiple carbohydrate binding sites in a single molecule of MBL (also called mannose-binding protein, mannan-binding protein or or MBP) allows strong binding to mannose residues on the phospholipid bilayer of microbial pathogens. Upon binding, activation of the complement system leads to the deposition of complement components on the surface of the microorganisms (opsonisation), followed by their clearance by phagocytic cells. Administration of the agent to deficient individuals may restore lectin function in vivo.
Industry:Pharmaceutical
A recombinant protein that inactivates the ribosome with potential antineoplastic and immunomodulating activities. Ribosome-inactivating protein CY503 binds to the cell surface sialyltransferase CD75 and is internalized; intracellularly, CY503 cleaves an adenine-specific N-glycosidic bond on the 28S ribosomal subunit, which may result in tumor cell apoptosis. This agent has also been shown to activate natural killer (NK) cells, induce cytokine receptor expression, and stimulate the release of cytokines. CD75 is expressed on mature B-cells and subsets of T-cells and erythrocytes.
Industry:Pharmaceutical
A recombinant protein which is chemically identical to or similar to endogenous interleukin-7 (IL-7) with hematopoietic and immunopotentiating properties. Produced by bone marrow, thymic stromal, and spleen cells, the cytokine interleukin-7 is a hematopoietic growth factor for progenitor B cells and T cells and stimulates proliferation and differentiation of mature T-cells and natural killer cells.
Industry:Pharmaceutical
A recombinant replication-defective adenovirus which encodes the gene for the cytokine human interferon-beta (IFN-beta). Once inserted into and replicating in host tumor cells, recombinant adenovirus-hIFN-beta expresses human IFN-beta, which may stimulate an antiproliferative natural killer (NK) cell response against tumor cells and induce caspase-mediated tumor cell apoptosis.
Industry:Pharmaceutical
A recombinant single-chain polypeptide engineered to exhibit the full binding and activity of an anti-CD37 monoclonal antibody with potential immunostimulatory and antineoplastic activities. Anti-CD37 single-chain polypeptide TRU-016 binds to CD37 on B-cells, which may result in antibody-dependent cell-mediated cytotoxicity (ADCC) and apoptosis. CD37 is a transmembrane glycoprotein expressed at high-levels on B cells and to a lesser extent on T cells and myeloid cells. This agent may have a longer half-life in vivo than conventional monoclonal antibodies.
Industry:Pharmaceutical
A recombinant therapeutic agent that is chemically identical to or similar to the endogenous cytokine human erythropoietin (EPO). Produced primarily by cells of the peritubular capillary endothelium of the kidney in response to hypoxia, circulating EPO binds to EPO receptors on the surface of committed erythroid progenitors in the bone marrow resulting in their replication and maturation into functional erythrocytes.
Industry:Pharmaceutical
A recombinant therapeutic agent that is identical or similar to an 84-amino-acid polypeptide produced by the parathryoid gland which functions to maintain a constant concentration of calcium ions (Ca2+) in the extracellular fluid. In target tissues, parathyroid hormone (PTH) binds to and activates the parathryorid hormone receptor (PTHR), a cell surface G protein-coupled receptor; there are two types of receptors, parathyroid hormone receptor 1 (PTH1R) found in bone and the kidney and parathyroid hormone receptor 2 (PTH2R) found primarily in the central nervous system (CNS), pancreas, testis, and placenta. Activation of PTHRs results in the activation of adenylyl cyclase and phospholipase C in target tissue cells, which, depending upon the specific target tissue, results in the enhancement of intestinal Ca2+ absorption, mobilization of bone Ca2+, and renal Ca2+ reabsorption.
Industry:Pharmaceutical
A recombinant therapeutic agent which is chemically identical to or similar to an endogenous non-mutated melanocyte differentiation antigen expressed by both normal and malignant melanocytes. Vaccinations with recombinant tyrosinase-related protein-2 may elicit an antitumoral cytotoxic T-cell response against tumor cells and some normal cells that express tyrosinase-related protein-2.
