Abstract

Gut microbiota is closely related to the Parkinson's disease (PD) pathogenesis. Additionally, aggregation of α-synuclein (α-syn) is central to PD pathogenesis. Here we identified the further mechanisms of gut microbiota in PD. A mouse model with PD was established via injection of MPTP. Normal or MPTP-induced PD like animals were treated with FMT from healthy normal mice. Pole test and traction test were performed to examine the effects of FMT on motor function of PD mice. Fecal SCFAs were assessed by gas chromatography-mass spectrometry. The α-syn level in the substantia nigra pars compacta (SN) of mice was measured using western blot. Dopaminergic neurons and microglial activation in the SN were analyzed by immunohistochemistry (IHC) and immunofluorescence (IF) staining. FMT alleviated physical impairment, decreased fecal SCFAs in a mouse model of PD. Additionally, FMT decreased the expression of α-syn, as well as inhibited the activation of microglia in the SN, and blocked the TLR4/PI3K/AKT/NF-κB signaling in the SN and striatum. FMT could protect mice against PD via suppressing α-syn expression and inactivating the TLR4/PI3K/AKT/NF-κB signaling.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Reduction of SCFAs in MPTP-induced mice yields beneficial effects, including alleviation of motor dysfunction and microglial and astrocytic activation in the SN.

    “Conversely, the reduction of SCFAs in MPTP-induced mice yielded beneficial effects, including alleviation of motor dysfunction, microglial and astrocytic activation in the SN.217,333”
  • The beneficial effect of FMT on neuroinflammation is ascribed to GM modulating microglia and astrocyte activation in SN by regulating the TLR4/NF-κB pathway and reducing expression of GSK3β, iNOS and IL-1β.

    “This beneficial effect should be ascribed to the ability of GM to modulate microglia and astrocyte activation in SN by regulating the TLR4/NF-κB pro-inflammatory pathway and reducing the expression of GSK3β, iNOS and IL-1β, which are implicated in PD pathogenesis and progression [469,470,471,472,478,479,480].”
  • FMT contrasts cognitive damage by decreasing α-synuclein expression and restoring optimal levels of striatal dopamine and serotonin, supporting neuroprotection.

    “At the brain level, FMT contrasts cognitive damage by decreasing α-synuclein expression and restoring the optimal levels of the striatal neurotransmitters dopamine and serotonin, thus supporting neuroprotection [469,471,473].”
  • Consistent preclinical studies and a handful of human case reports have shown that FMT might reduce motor and non-motor symptoms, as well as constipation, in PD at least in the short term.

    “Concerning PD, consistent preclinical studies and a handful of human case reports have shown that FMT might be exploited to reduce motor and non-motor symptoms, as well as constipation, at least in the short term [40,465,469,470,471,472,473,474,475,476,477] (Table 4).”
  • Decreased neuroinflammation following FMT has been reported by numerous preclinical studies.

    “Notably, decreased neuroinflammation following FMT has been reported by numerous preclinical studies [469,470,471,472].”

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.
