WebbFenfluramine is an amphetamine derivative drug that was once widely prescribed as an appetite suppressant to treat obesity. Fenfluramine is devoid of the psychomotor stimulant and abuse potential of D-amphetamine and interacts with certain 5 -hydroxy tryptamine (serotonin, 5-HT) receptors and the serotonin transporter to release 5-HT from neurons.

Schwann cells are named after German physiologist Theodor Schwann, who discovered them in the 19th century. These cells are equivalent to a type of neuroglia called oligodendrocytes, which occur in the …
WebbHigh concentrations of 17b-estradiol have a toxic effect on Schwann cells The effect of E2 on SCs survival was measured after either a 24 or 48 h incubation time (Fig. 2). In this experiment, primary SC cultures were exposed to varying concentrations of E2 in the culture media for 24 or 48 h and cell viability was calculated using the MTT assay. Webb17 jan. 2006 · Myelin basic protein (MBP) binds to negatively charged lipids on the cytosolic surface of oligodendrocyte membranes and is most likely responsible for adhesion of these surfaces in the multilayered myelin sheath. It can also polymerize actin, bundle F-actin filaments, and bind actin filaments to lip …
