Recent studies link synaptojanin 1 (synj1), the main phosphoinositol (4,5)-biphosphate phosphatase (PI(4,5)P2-degrading enzyme) in the brain and synapses, to Alzheimer disease. Here we report a novel mechanism by which synj1 reversely regulates cellular clearance of amyloid-β (Aβ). Genetic down-regulation of synj1 reduces both extracellular and(More)
An increase in amyloid-β (Aβ) production is a major pathogenic mechanism associated with Alzheimer's disease (AD), but little is known about possible homeostatic control of the amyloidogenic pathway. Here we report that the amyloid precursor protein (APP) intracellular domain (AICD) downregulates Wiskott-Aldrich syndrome protein (WASP)-family verprolin(More)
Neurotoxic amyloid-β peptides (Aβ) are major drivers of Alzheimer's disease (AD) and are formed by sequential cleavage of the amyloid precursor protein (APP) by β-secretase (BACE) and γ-secretase. Our previous study showed that the anticancer drug Gleevec lowers Aβ levels through indirect inhibition of γ-secretase activity. Here we report that Gleevec also(More)
