Monoclonal Antibodies
A monoclonal antibody (mAb, more rarely called moAb) is an antibody produced from a cell Lineage made by cloning a unique white blood cell. All subsequent antibodies derived this way trace back to a unique parent cell. Monoclonal antibodies can have monovalent affinity, binding only to the same epitope (the part of an antigen that is recognized by the antibody). In contrast, polyclonal antibodies bind to multiple epitopes and are usually made by several different antibody-secreting plasma cell lineages. Bispecific monoclonal antibodies can also be engineered, by increasing the therapeutic targets of one monoclonal antibody to two epitopes. It is possible to produce monoclonal antibodies that specifically bind to virtually any suitable substance; they can then serve to detect or purify it. This capability has become an investigative tool in biochemistry, molecular biology, and medicine. Monoclonal antibodies are being used on a clinical level for both the diagnosis and therapy ...

CA-125
Mucin-16 (MUC-16) also known as Ovarian cancer-related tumor marker CA125 is a protein that in humans is encoded by the ''MUC16'' gene. MUC-16 is a member of the mucin family glycoproteins. MUC-16 has found application as a tumor marker or biomarker that may be elevated in the blood of some patients with specific types of cancers, most notably ovarian cancer, or other conditions that are benign. Structure Mucin 16 is a membrane associated mucin that possesses a single transmembrane domain. A unique property of MUC16 is its large size. MUC16 is more than twice as long as MUC1 and MUC4 and contains about 22,000 amino acids, making it the largest membrane-associated mucin. MUC16 is composed of three different domains: * An N-terminal domain * A tandem repeat domain * A C-terminal domain The N-terminal and tandem repeat domains are both entirely extracellular and highly O-glycosylated. All mucins contain a tandem repeat domain that has repeating amino acid sequences high in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inflammatory Bowel Disease
Inflammatory bowel disease (IBD) is a group of inflammation, inflammatory conditions of the colon (anatomy), colon and small intestine, Crohn's disease and ulcerative colitis being the principal types. Crohn's disease affects the small intestine and large intestine, as well as the mouth, esophagus, stomach and the anus, whereas ulcerative colitis primarily affects the colon and the rectum. IBD also occurs in dogs and is thought to arise from a combination of host genetics, intestinal microenvironment, environmental components and the immune system. There is an ongoing discussion, however, that the term "chronic enteropathy" might be better to use than "inflammatory bowel disease" in dogs because it differs from IBD in humans in how the dogs respond to treatment. For example, many dogs respond to only dietary changes compared to humans with IBD, who often need Immunosuppression, immunosuppressive treatment. Some dogs may also need immunosuppressant or antibiotic treatment when dieta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Integrin Beta 7
Integrin beta-7 is an integrin protein that in humans is encoded by the ''ITGB7'' gene. It can pair with ITGA4 (CD49d) to form the heterodimeric integrin receptor αβ, or with ITGAE (CD103) to form αβ. Structure Like all integrin subunits, β is a highly flexible, membrane-bound, extracellular protein that must pair with an α subunit for stability. The molecule's flexibility allows it to dynamically regulate its affinity for ligand through conformational changes. Beginning with the apical end of the protein, farthest from the cell membrane, the β is composed of a head and upper legs, collectively known as the headpiece, lower legs, a transmembrane domain and a cytoplasmic tail. The top of the head is the I-like domain, sometimes called the βI domain, which, in combination with the α subunit, binds ligand. Just below this is the hybrid domain, a portion of which is N-terminal to the I-like domain. Below the hybrid domain is the PSI domain, which completes the headpiece. ...

Integrin Alpha 4
CD49d is an integrin alpha subunit. It makes up half of the α4β1 lymphocyte homing receptor. Function The product of this gene belongs to the integrin alpha chain family of proteins. Integrins are heterodimeric integral membrane proteins composed of an alpha chain and a beta chain. This gene encodes an alpha 4 chain. Unlike other integrin alpha chains, alpha 4 neither contains an I-domain, nor undergoes disulfide-linked cleavage. Alpha 4 chain associates with either beta 1 chain or beta 7 chain. Interactions CD49d has been shown to interact with LGALS8 and Paxillin. See also * Carotegrast methyl Carotegrast methyl (trade name Carogra) is a drug used for the treatment of ulcerative colitis.

Integrin
Integrins are transmembrane receptors that facilitate cell-cell and cell-extracellular matrix (ECM) adhesion. Upon ligand binding, integrins activate signal transduction pathways that mediate cellular signals such as regulation of the cell cycle, organization of the intracellular cytoskeleton, and movement of new receptors to the cell membrane. The presence of integrins allows rapid and flexible responses to events at the cell surface (''e.g''. signal platelets to initiate an interaction with coagulation factors). Several types of integrins exist, and one cell generally has multiple different types on its surface. Integrins are found in all animals while integrin-like receptors are found in plant cells. Integrins work alongside other proteins such as cadherins, the immunoglobulin superfamily cell adhesion molecules, selectins and syndecans, to mediate cell–cell and cell–matrix interaction. Ligands for integrins include fibronectin, vitronectin, collagen and laminin. Stru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Interleukin 13
Interleukin 13 (IL-13) is a protein that in humans is encoded by the ''IL13'' gene. IL-13 was first cloned in 1993 and is located on chromosome 5q31 with a length of 1.4kb. It has a mass of 13 kDa and folds into 4 alpha helical bundles. The secondary structural features of IL-13 are similar to that of Interleukin 4 (IL-4); however it only has 25% sequence identity to IL-4 and is capable of IL-4 independent signaling. IL-13 is a cytokine secreted by T helper type 2 (Th2) cells, CD4 cells, natural killer T cell, mast cells, basophils, eosinophils and nuocytes. Interleukin-13 is a central regulator in IgE synthesis, goblet cell hyperplasia, mucus hypersecretion, airway hyperresponsiveness, fibrosis and chitinase up-regulation. It is a mediator of allergic inflammation and different diseases including asthma. Functions IL-13 has effects on immune cells that are similar to those of the closely related cytokine IL-4. However, IL-13 is suspected to be the central mediator of the physi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CD51
Integrin alpha-V is a protein that in humans is encoded by the ''ITGAV'' gene. Function ITGAV encodes integrin alpha chain V. Integrins are heterodimeric integral membrane proteins composed of an alpha chain and a beta chain. Alpha V undergoes post-translational cleavage to yield disulfide-linked heavy and light chains, that combine with multiple integrin beta chains to form different integrins. Among the known associating beta chains (beta chains 1,3,5,6, and 8; 'ITGB1', 'ITGB3', 'ITGB5', 'ITGB6', and 'ITGB8'), each can interact with extracellular matrix ligands; the alpha V beta 3 integrin, perhaps the most studied of these, is referred to as the Vitronectin receptor (VNR). In addition to adhesion, many integrins are known to facilitate signal transduction. Alpha V class integrins In mammals the integrins that include alpha-V are : Clinical significance Overexpression of the ITGAV gene is associated with progression and spread of colorectal cancer, and prostate cancer.

Abituzumab
Abituzumab is a humanized IgG2 monoclonal antibody (mAb) targeted at CD51 (an integrin) currently in development by Merck KGaA Darmstadt, Germany in an attempt to prevent bone lesion metastases in castration-resistant prostate cancer. Pharmacology Pharmacokinetics Early results from clinical trials show that there are no severe dose-dependent adverse effects up to 1500 mg IV administration of Abituzumab. Maximum serum concentrations were observed one to two hours after the onset of administration, with a Cmax that increased proportionally with dose. Serum half-life is also dose-dependent, at 35 mg the half-life is 19.3 hours, and at 1500 mg half-life is 246.1 hours. Clearance of Abituzumab began to stabilize at 250 mg, which may suggest saturable first-order elimination kinetics. Volume of distribution remained constant between 4.1 - 5.9 L at all doses of Abituzumab, which indicates minimal distribution in the tissue. Anti-abituzumab antibodies were observe ...

Platelet Aggregation Inhibitor
An antiplatelet drug (antiaggregant), also known as a platelet agglutination inhibitor or platelet aggregation inhibitor, is a member of a class of pharmaceuticals that decrease platelet aggregation and inhibit thrombus formation. They are effective in the arterial circulation where anticoagulants have little effect. They are widely used in primary and secondary prevention of thrombotic cerebrovascular or cardiovascular disease. Antiplatelet therapy with one or more of these drugs decreases the ability of blood clots to form by interfering with the platelet activation process in primary hemostasis. Antiplatelet drugs can reversibly or irreversibly inhibit the process involved in platelet activation resulting in decreased tendency of platelets to adhere to one another and to damaged blood vessels' endothelium. Choice A 2006 review states: "...low-dose aspirin increases the risk of major bleeding 2-fold compared with placebo. However, the annual incidence of major bleeding due ...
