Role Of Membrane Gm1 On Early Neuronal Membrane Actions Of Aβ During Onset Of Alzheimer's Disease, E. J. Fernandez-Perez, Fernando Sepulveda, Robert W. Peoples, Luis G. Aguayo

Biomedical Sciences Faculty Research and Publications

The ability of beta-amyloid peptide (Aβ) to disrupt the plasma membrane through formation of pores and membrane breakage has been previously described. However, the molecular determinants for these effects are largely unknown. In this study, we examined if the association and subsequent membrane perforation induced by Aβ was dependent on GM1levels. Pretreatment of hippocampal neurons with D-PDMP decreased GM1 and Aβ clustering at the membrane (Aβ fluorescent-punctas/20 μm, control = 16.2 ± 1.1 vs. D-PDMP = 6.4 ± 0.4, p < 0.001). Interestingly, membrane perforation with Aβ occurred with a slower time course when the GM1 content was diminished (time to establish perforated configuration (TEPC) (min): control = 7.8 ± 2 vs. low GM1 = 12.1 ± 0.5, p < 0.01), suggesting that the presence of GM1 in the membrane can modulate the distribution and the membrane perforation by Aβ. On the other hand, increasing GM1 facilitated the membrane perforation (TEPC: control = 7.8 ± 2 vs. GM1 = 6.2 ± 1 min, p < 0.05). Additionally, using Cholera Toxin Subunit-B (CTB) to block the interaction of Aβ with GM1 attenuated membrane perforation significantly. Furthermore, …

Corticosterone Regulates Both Naturally Occurring And Cocaine‐Induced Dopamine Signaling By Selectively Decreasing Dopamine Uptake, Daniel S. Wheeler, Amanda L. Ebben, Beliz Kurtoglu, Marissa E. Lovell, Austin T. Bohn, Isabella A. Jasek, David A. Baker, John R. Mantsch, Paul J. Gasser, Robert A. Wheeler

Biomedical Sciences Faculty Research and Publications

Stressful and aversive events promote maladaptive reward‐seeking behaviors such as drug addiction by acting, in part, on the mesolimbic dopamine system. Using animal models, data from our laboratory and others show that stress and cocaine can interact to produce a synergistic effect on reward circuitry. This effect is also observed when the stress hormone corticosterone is administered directly into the nucleus accumbens (NAc), indicating that glucocorticoids act locally in dopamine terminal regions to enhance cocaine's effects on dopamine signaling. However, prior studies in behaving animals have not provided mechanistic insight. Using fast‐scan cyclic voltammetry, we examined the effect of systemic …
