Prion protein and Abeta-related synaptic toxicity impairment


Calella, A M; Farinelli, M; Nuvolone, M; Mirante, O; Moos, R; Falsig, J; Mansuy, I M; Aguzzi, A (2010). Prion protein and Abeta-related synaptic toxicity impairment. EMBO Molecular Medicine, 2(8):306-314.

Abstract

Alzheimer's disease (AD), the most common neurodegenerative disorder, goes along with extracellular amyloid-beta (Abeta) deposits. The cognitive decline observed during AD progression correlates with damaged spines, dendrites and synapses in hippocampus and cortex. Numerous studies have shown that Abeta oligomers, both synthetic and derived from cultures and AD brains, potently impair synaptic structure and functions. The cellular prion protein (PrP(C)) was proposed to mediate this effect. We report that ablation or overexpression of PrP(C) had no effect on the impairment of hippocampal synaptic plasticity in a transgenic model of AD. These findings challenge the role of PrP(C) as a mediator of Abeta toxicity.
