The transporter protein may be an endogenous peptide, or peptidomimetic monoclonal antibody, which undergoes RMT across the BBB via transport on brain endothelial receptors such as the insulin receptor or transferrin receptor. The transporter protein acts as a molecular Trojan horse to ferry into brain the therapeutic protein that is ...
Human transferrin is encoded by the TF gene and produced as a 76 kDa glycoprotein. [7] [8] Transferrin glycoproteins bind iron tightly, but reversibly. Although iron bound to transferrin is less than 0.1% (4 mg) of total body iron, it forms the most vital iron pool with the highest rate of turnover (25 mg/24 h).
All plasma proteins except Gamma-globulins are synthesised in the liver. [1] Human serum albumin, osmolyte and carrier protein; α-fetoprotein, the fetal counterpart of serum albumin; Soluble plasma fibronectin, forming a blood clot that stops bleeding; C-reactive protein, opsonin on microbes, [2] acute phase protein; Various other globulins
Lipoproteins may be classified as five major groups, listed from larger and lower density to smaller and higher density. Lipoproteins are larger and less dense when the fat to protein ratio is increased. They are classified on the basis of electrophoresis, ultracentrifugation and nuclear magnetic resonance spectroscopy via the Vantera Analyzer ...
Due to the hydrophobic nature of membrane lipids, triglycerides and cholesterols, they require special transport proteins known as lipoproteins. [1] The amphipathic structure of lipoproteins allows the triglycerides and cholesterol to be transported through the blood. Chylomicrons are one sub-group of lipoproteins which carry the digested ...
Lipoproteins transfer lipids around the body in the extracellular fluid, making fats available to body cells for receptor-mediated endocytosis. [2] [3] Lipoproteins are complex particles composed of multiple proteins, typically 80–100 proteins per particle (organized by a single apolipoprotein B for LDL and the larger particles).
Plasma proteins, sometimes referred to as blood proteins, are proteins present in blood plasma. They serve many different functions, including transport of lipids, hormones, vitamins and minerals in activity and functioning of the immune system. Other blood proteins act as enzymes, complement components, protease inhibitors or kinin precursors.
Hyperlipidemia is the presence of elevated or abnormal levels of lipids and/or lipoproteins in the blood. Lipid and lipoprotein abnormalities are extremely common in the general population, and are regarded as a highly modifiable risk factor for cardiovascular disease. In addition, some forms may predispose to acute pancreatitis.
