Anesthesiology

The incidence of Alzheimer disease may increase after surgical interventions. Amyloid β-protein (Aβ) fibrillogenesis, which is closely related to Alzheimer disease, is reportedly accelerated by exposure to anesthetics. However, the effects of GM1 ganglioside (GM1) on Αβ fibrillogenesis have not yet been reported. The current study was designed to examine whether the anesthetics propofol and thiopental are associated with Αβ assembly and GM1 expression on the neuronal cell surface. ⋯ Propofol and thiopental have direct and indirect inhibitory effects on Αβ fibrillogenesis.
