Abstract

Background/aims Vascular dementia (VD) is accompanied by severe neuronal damage. Exosomal microRNAs (miRs) have been implicated in the neuroprotective effect of neural stem cells (NSCs), and miR-132-3p is a proneurogenic miR. In this study, we aimed to explore the role and underlying mechanisms of miR-132-3p-enriched NSC-EXs in VD-induced neuronal damage and synaptic impairment. Methods NSC-EXs, NSC-EXs enriched with miR-132-3p (NSC-EXs miR-132-3p ), and NSC-EXs deficient in miR-132-3p (NSC-EXs simiR-132-3p ) were cocultured with oxygen- and glucose-deprived (OGD)-injured neurons or administered to VD mice. Bioinformatic analyses and luciferase assays were used to determine the target genes of miR-132-3p. Results The levels of NSC-EXs and their associated miR-132-3p were markedly decreased in the hippocampi of VD mice. Compared with NSC-EXs, the infusion of NSC-EXs miR-132-3p was more effective at increasing the miR-132-3p level, neuron number, dendritic spine density and cognitive function and decreasing neuronal ROS production and apoptosis, whereas NSC-EXs simiR-132-3p treatment resulted in attenuated effects in comparison with those of NSC-EXs. In OGD-treated neurons, incubation with NSC-EXs miR-132-3p increased neurite outgrowth and decreased neuronal ROS production and apoptosis. Moreover, through bioinformatic analysis and cell transfection, we confirmed that NSC-EXs miR-132-3p promoted neurite outgrowth by targeting RASA1 and increasing the expression of downstream Ra…

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.
