Lipid-core nanocapsules improve the effects of resveratrol against Abeta-induced neuroinflammation.

Resveratrol, a natural polyphenolic compound, has attracted considerable interest for its anti-inflammatory and neuroprotective properties. However, the biological effects of resveratrol appear strongly limited because it is photosensitive, easily oxidized, and has unfavorable pharmacokinetics. The present study aimed to elucidate the effect of resveratrol on Abeta-triggered neuroinflammation by comparing the effects of free resveratrol (RSV) treatment with those of treatment with resveratrol-loaded lipid-core nanocapsules (RSV-LNC).

Free and nanoencapsulated curcumin suppress β-amyloid-induced cognitive impairments in rats: involvement of BDNF and Akt/GSK-3β signaling pathway.

Alzheimer's disease (AD), a neurodegenerative disorder exhibiting progressive loss of memory and cognitive functions, is characterized by the presence of neuritic plaques composed of neurofibrillary tangles and β-amyloid (Aβ) peptide. Drug delivery to the brain still remains highly challenging for the treatment of AD. Several studies have been shown that curcumin is associated with anti-amyloidogenic properties, but therapeutic application of its beneficial effects is limited.

The curry spice curcumin attenuates beta-amyloid-induced toxicity through beta-catenin and PI3K signaling in rat organotypic hippocampal slice culture.

Objective: Accumulating evidence indicates that curcumin potently protects against beta-amyloid (Abeta) due to its oxygen free radicals scavenging and anti-inflammatory properties. However, cellular mechanisms that may underlie the neuroprotective effect of curcumin in Abeta-induced toxicity are not fully understood yet. The present study was undertaken to investigate the mechanisms involved in neuroprotective effects of curcumin, particularly involving Wnt/beta-catenin and PI3K pathways.

Neuroprotective effects of resveratrol against Aβ administration in rats are improved by lipid-core nanocapsules.

Alzheimer's disease (AD), a neurodegenerative disorder exhibiting a gradual decline in cognitive function, is characterized by the presence of neuritic plaques composed of neurofibrillary tangles and amyloid-β (Aβ) peptide. Available drugs for AD therapy have small effect sizes and do not alter disease progression. Several studies have been shown that resveratrol is associated with anti-amyloidogenic properties, but therapeutic application of its beneficial effects is limited.
