Abstract

Microglia‑mediated neuroinflammation is key in the pathogenesis of Alzheimer's disease (AD). Several studies have suggested that NADPH oxidase contributes to microglia‑mediated neuroinflammation. Resveratrol, which is a natural polyphenolic compound, exerts neuroprotective effects in AD due to its anti‑inflammatory properties. The present study aimed to investigate the effects of resveratrol on the activation of oligomeric amyloid β (oAβ)‑induced BV‑2 microglia, and to determine the role of NADPH oxidase in these effects. Microglial proliferation was measured by high‑content screening cell counting and using a bromodeoxyuridine incorporation assay. In addition, the levels of reactive oxygen species (ROS), nitric oxide (NO), tumor necrosis factor (TNF)‑α and interleukin (IL)‑1β were assessed. The results of the present study demonstrated that resveratrol inhibited the proliferation of oAβ‑induced microglia and the production of pro‑inflammatory factors, including ROS, NO, TNF‑α and IL‑1β. Subsequent mechanistic investigations demonstrated that resveratrol inhibited the oAβ‑induced mRNA and protein expression levels of p47phox and gp91phox. These results suggested that NADPH oxidase may be a potential target for AD treatment, and resveratrol may be a valuable natural product possessing therapeutic potential against AD.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
