Molecular interplay between mTOR, amyloid-beta, and Tau: effects on cognitive impairments

What this study shows

Revealed a vicious cycle: amyloid-beta RAISES mTOR activity, and high mTOR in turn blocks the autophagy needed to clear amyloid and tau - so the disease feeds itself. Rapamycin broke the loop in 3xTg-AD mice, rescuing memory and lowering BOTH amyloid and tau, with autophagy shown to be required for the effect.

Abstract

ShowHide

Accumulation of amyloid-beta (Abeta) and Tau is an invariant feature of Alzheimer disease (AD). The upstream role of Abeta accumulation in the disease pathogenesis is widely accepted, and there is strong evidence showing that Abeta accumulation causes cognitive impairments. However, the molecular mechanisms linking Abeta to cognitive decline remain to be elucidated. Here we show that the buildup of Abeta increases the mammalian target of rapamycin (mTOR) signaling, whereas decreasing mTOR signaling reduces Abeta levels, thereby highlighting an interrelation between mTOR signaling and Abeta.
