γ-Secretase modulators (GSMs) inhibit the generation of amyloidogenic Aβ42 peptides and are promising agents for treatment or prevention of Alzheimer's disease (AD). Recently, a second generation of GSMs with favorable pharmacological properties has emerged, but preclinical studies to assess their efficacy in vivo are lacking. Such studies rely on(More)
Alzheimer disease is characterized by pathological aggregation of two proteins, tau and Abeta-amyloid, both of which are considered to be toxic to neurons. In this review we summarize recent advances on small molecule inhibitors of protein aggregation with emphasis on tau, with activities mediated by the direct interference of self-assembly. The inhibitors(More)
The two histopathological hallmarks that characterize Alz-heimers disease (AD) are the extracellular amyloid plaques that are formed by b-amyloid fragments of the amyloid precursor protein (APP), and intracellular neurofibrillary tangles and neuropil threads, which consist of the micro-tubule-associated protein tau forming paired helical filaments with(More)
Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that has been reported to reduce the risk of developing Alzheimer's disease (AD). Its preventive effects in AD are likely pleiotropic as ibuprofen displays both anti-inflammatory activity by inhibition of cyclooxygenases and anti-amyloidogenic activity by modulation of γ-secretase. In order to study(More)
The intramembrane-cleaving protease γ-secretase catalyzes the last step in the generation of toxic amyloid-β (Aβ) peptides and is a principal therapeutic target in Alzheimer's disease. Both preclinical and clinical studies have demonstrated that inhibition of γ-secretase is associated with prohibitive side effects due to suppression of Notch processing and(More)
Comprehensive evidence supports that oligomerization and accumulation of amyloidogenic Aβ42 peptides in brain is crucial in the pathogenesis of both familial and sporadic forms of Alzheimer's disease. Imaging studies indicate that the buildup of Aβ begins many years before the onset of clinical symptoms, and that subsequent neurodegeneration and cognitive(More)
Chemokines are important modulators of neuroinflammation and neurodegeneration. In the brains of Alzheimer's disease (AD) patients and in AD animal models, the chemokine CXCL10 is found in high concentrations, suggesting a pathogenic role for this chemokine and its receptor, CXCR3. Recent studies aimed at addressing the role of CXCR3 in neurological(More)
