Retinoic Acid Attenuates β-Amyloid Deposition and Rescues Memory Deficits in an Alzheimer's Disease Transgenic Mouse Model

Abstract: Recent studies have revealed that disruption of vitamin A signaling observed in Alzheimer's disease (AD) leads to ␤-amyloid (A␤) accumulation and memory deficits in rodents. The aim of the present study was to evaluate the therapeutic effect of all-trans retinoic acid (ATRA), an active metabolite of vitamin A, on the neuropathology and deficits of spatial learning and memory in amyloid precursor protein (APP) and presenilin 1 (PS1) double-transgenic mice, a well established AD mouse model. Here we report a rob… Show more

“…In AD patients, serum concentrations of vitamins A, C, E, and ␤-carotene are significantly lower than in normal individuals (48). All-trans-RA inhibits APP processing and hyperphosphorylation and rescues the impairment of spatial learning and memory in amyloid model mice (49). Furthermore, 9-cis-RA suppresses A␤ production in vitro (50).…”

“…An impairment of spatial learning and memory performance has been suggested in leptin-insensitive animals (10), while exogenous leptin promotes spatial learning and memory tasks in the Morris water maze (8,9,11). Furthermore, the accumulation of Aβ and dementia has been linked to the reduction of leptin (7,12).…”
