The enzyme 5-lipoxygenase (5LO) is upregulated in Alzheimer's disease (AD), and its pharmacologic blockade with zileuton slows down the development of the AD-like phenotype in young AD mice. However, its efficacy after the AD pathology is established is unknown. To this end, starting at 12 months of age triple transgenic mice (3xTg) received zileuton, a(More)
FLAP (5-lipoxygenase-activating protein) is a protein widely distributed within the central nervous system whose function is to regulate the activation of the 5-Lipoxygenase enzyme. Although previous works show that pharmacological blockade of FLAP improve the amyloidotic phenotype of the Tg2576, its contribution to tau pathology remains to be investigated.(More)
Beside amyloid-β plaques and neurofibrillary tangles, brain oxidative damage has been constantly implicated in Alzheimer's disease (AD) pathogenesis. Numerous studies demonstrated that F2-isoprostanes, markers of in vivo lipid peroxidation, are elevated in AD patients and mouse models of the disease. Previously, we showed that the 8-isoprostaneF2α, (8ISO)(More)
Parkinson's disease (PD) is a chronic and progressive neurodegenerative disorder. Although rare genetically linked cases of PD have been reported, most incidences are sporadic in nature. Late-onset, sporadic PD is thought to result from the combined effects of genetic and environmental risk factors exposure. Sleep and circadian rhythm disorders are(More)
Dysregulation of stress hormones, such as glucocorticoids, in adult life increases the risk to develop Alzheimer's disease (AD). However, the effect of prenatal glucocorticoids exposure on AD development in the offspring remains unknown. We studied how gestational dexamethasone exposure influences the AD-like phenotype in the offspring of triple transgenic(More)
Environmental stressor exposure is associated with a variety of age-related diseases including neurodegeneration. Although the initial events of sporadic Parkinson's disease (PD) are not known, consistent evidence supports the hypothesis that the disease results from the combined effect of genetic and environmental risk factors. Among them, behavioral(More)
Alterations of glucose metabolism have been observed in Alzheimer's disease (AD) brain. Previous studies showed that glucose deprivation increases amyloidogenesis via a BACE-1-dependent mechanism. However, no data are available on the effect that this condition may have on tau phosphorylation. In this study, we exposed neuronal cells to a glucose-free(More)
