Carvedilol protection against endogenous Aβ-induced neurotoxicity in N2a cells.

ABSTRACT: Mutations in amyloid precursor protein (APP) and presenilin1 result in overproduction and accumulation of β-amyloid (Aβ) peptide, which has been shown to play an important role in Alzheimer's disease (AD) pathogenesis. Carvedilol, a nonselective β-adrenergic receptor blocker used for treatment for heart failure and hypertension, has displayed its neuroprotective capacity due to its antioxidant property. In this study, we investigated whether Carvedilol has a neuronal protective effect against endogenous Aβ neurotoxicity in mouse Neuro2a (N2a) cells transfected with Swedish amyloid precursor protein (Swe-APP) mutant and Presenilin exon9 deletion mutant (N2a/Swe.D9). Elevated levels of reactive oxygen species (ROS), protein carbonyls, and 4-HNE were found in N2a/Swe.D9 cells, which were amel
