Results: Five systematic reviews were identified. These incorporated findings from cohort, cross-sectional, URMC-099 mw and case-control studies, and the outcomes examined included Alzheimer’s disease, vascular dementia, nonspecified dementia, all dementias, and cognitive decline or cognitive impairment. Education, occupation, and leisure or mentally stimulating activities were suggested

to supply cognitive reserve and offer a protective effect against the risk of dementia. Premorbid IQ and socioeconomic status have not been investigated as thoroughly and showed inconsistent results. Two of the reviews showed that when combining different indicators in the analyses/definition, including education, occupation, mentally stimulating activities, and premorbid IQ, cognitive reserve had a protective effect against cognitive decline. However, other indicators may also supply

the reserve, including dietary habits and genetic indicators, but research is lacking with regard to creating a full cognitive reserve model. Conclusions: This review highlights the lack of consensus regarding a definition of cognitive reserve. Further research is required to clarify how the indicators already identified may provide cognitive reserve and offer a protective effect against dementia. selleck kinase inhibitor Agreement on the indicators that constitute the cognitive reserve model is needed before testing possible interventions that may increase the reserve supply and improve cognition.”
“Caspases, effectors of apoptosis, are key mediators of neuronal death in several neurodegenerative diseases. Caspase-8 and Pevonedistat solubility dmso caspase-6 have been implicated in the pathogenesis of amyotrophic lateral sclerosis, multiple sclerosis, Parkinson’s disease, and Alzheimer’s disease (AD). ss-Amyloid precursor protein (APP) is cleaved at Asp664 in its intracellular domain by caspase-8. We and other laboratories recently showed

that obliteration of the caspase cleavage site on APP alleviates functional AD-like deficits in a mouse model. Therefore, caspase cleavage of APP constitutes a potential novel target for therapeutic intervention. To identify chemical inhibitors of caspase-8 cleavage, we screened a subset of the chemical library at the Harvard NeuroDiscovery Center’s Laboratory for Drug Discovery in Neurodegeneration. We show that caspase-8, but not caspase-1, -3, or -9, cleaves a biotinylated peptide derived from APP at Asp664, and we report the development of a sensitive high-throughput assay for caspase-8 cleavage of APP and the use of that assay for the identification of specific small molecule “hit” compounds that potently inhibit Asp664 cleavage of APP. Furthermore, we demonstrate that one of these compounds (LDN-0021835) inhibits the cleavage of APP at Asp664 in cell-based assays. (C) 2011 Elsevier Inc. All rights reserved.”
