Abstract

Current strategies for the treatment of Alzheimer's disease (AD) focus on the pathology in the later stages of disease progression. Early microglia abnormality and β-amyloid (Aβ) deposition trigger disease development before identical symptoms emerge, which leads to poor clinical treatment effects in the later stages. In the early stage of disease progression, microglia in brains of 5XFAD mice have been activated by Aβ plaques to secrete more pro-inflammatory cytokines. In the meantime, these cytokines up-regulate Aβ via increasing the APP processing. Sodium butyrate (NaB), as one of the short chain fatty acid (SCFA) generated by gut microbiota, is the inhibitor of histone deacetylase (HDAC), which reduces the secretion of pro-inflammatory cytokines. In our experiment, 8-week-old 5XFAD mice and their litter WT mice were treated with NaB or normal saline for 2 weeks (WT + Vehicle group, WT + NaB group, AD + Vehicle group and AD + NaB group). After treatment, behavioral tests were carried out. The novel object recognition (NOR) and Morris water maze (MWM) tests demonstrated that there was no significant difference between four groups of mice. The results of long-term potentiation (LTP) and depotentiation (DEP) illustrated that the synaptic plasticity was promoted in 5XFAD mice after treatment with NaB. Compared to the AD + Vehicle group, the dendritic spines were more abundant in other groups of mice. Furthermore, the synapse-associated proteins (PSD-95, SYP, NR2B) were reduced and the pro-inflammatory cytokines (TNF-α, IL-6, IL-1β) were increased in the AD + Vehicle group. These phenomena were reversed after treatment with NaB. Moreover, our results suggested that NaB suppressed the over-activation of microglia and the accumulation of Aβ in AD mice. Altogether, all results illustrated that HDAC inhibitor NaB could ameliorate the synaptic plasticity by reducing neuroinflammation in 5XFAD mice in the early stage of the disease.

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.
