SP8395: Antibodies and their antigen

Antibodies and their antigen. Computer model showing the molecular structure of two anti-P-glycoprotein antibodies (upper left and right) and the P-glycoprotein (blue) to which they respond. These antibodies will bind to the glycoprotein, preventing it from functioning. ©Laguna Design/Science Source

Strategy Developed to Improve Delivery of Medicines to the Brain - The experimental treatment method allows small therapeutic agents to safely cross the blood-brain barrier in laboratory rats by turning off P-glycoprotein, one of the main gatekeepers preventing medicinal drugs from reaching their intended targets in the brain.

Sucralose, A Synthetic Organochlorine Sweetener: Overview Of Biological IssuesThis review of the scientific literature on sucralose (Splenda) is cause for concern. Some of the biological effects of sucralose include:~ alterations in insulin, blood glucose, and glucagon-like peptide 1 (GLP-1) levels,~ metabolism of sucralose in the gastrointestinal tract to metabolites whose identity and safety profile are unknown,~ induction of cyctochrome P450 and P-glycoprotein in the gastrointestinal ...

Herbal elixir anyone? Mol Neurobiol. 2016 Dec 9. [Epub ahead of print] Matrine Treatment Blocks NogoA-Induced Neural Inhibitory Signaling Pathway in Ongoing Experimental Autoimmune Encephalomyelitis. Kan QC Zhang HJ Zhang Y Li X Xu YM Thome R Zhang ML Liu N Chu YJ Zhang GX Zhu L. Abstract Myelin-associated inhibitors such as NogoA myelin-associated glycoprotein (MAG) and oligodendrocyte myelin glycoprotein (OMgp) play a pivotal role in the lack of neuroregeneration in multiple sclerosis an…

Figure 3: Unhealthy diets such as high fat diets downregulate hepatic drug metabolism with the corruption of insulin therapy in diabetes and aging. Amyloid beta metabolism in the brain and liver are connected to drug metabolism and defective hepatic drug metabolism may be the primary defect in Type 3 diabetes with acceleration of neuronal apoptosis by abnormal brain amyloid beta metabolism associated with Type 1 or Type 2 diabetes. Abbreviations: P-gp1, P glycoprotein, PXR, pregnane X…

The blood–brain barrier allows the passage of water, some gases, and lipid-soluble molecules by passive diffusion, as well as the selective transport of molecules such as glucose and amino acids that are crucial to neural function. On the other hand, the blood–brain barrier may prevent the entry of lipophilic, potential neurotoxins by way of an active transport mechanism mediated by P-glycoprotein.
