Abstract

Glial cell line-derived neurotrophic factor (GDNF) offers the possibility to stimulate axonal regeneration of mesencephalic dopaminergic neurons, which are affected in Parkinson's disease. Nevertheless, a safe and efficient GDNF delivery system that may be used in clinical trials is still lacking. In a previous study, we showed that GDNF-releasing microspheres can deliver the neurotrophic factor for 2 months, allowing in a partial rat model of Parkinson's disease a sprouting of the preserved dopaminergic fibers and functional improvement 8 weeks after the treatment. The present study confirms these previous observations and shows that the amphetamine-induced rotation score is still decreased 24 weeks after the end of GDNF delivery. Nevertheless, the improvement was not statistically significant at the latest time point due to the spontaneous reinnervation observed in the model used.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

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?

  • Implantation of GDNF-loaded PLGA-MS in brains of PD animal models achieved regeneration of affected dopaminergic neurons accompanied by functional improvement.

    “The regeneration of affected dopaminergic neurons accompanied by functional improvement could be achieved through the implantation of glial cell-derived neurotrophic factor (GDNF)-loaded PLGA-MS in the brains of PD animal models.129”
  • GDNF-loaded microsphere increased TH-positive fibers in striatum and substantia nigra, suggesting neuroprotection and neurorestoration activity.

    “Apart from this GDNF-loaded microsphere increase in TH-positive fibers in the striatum and substantia nigra, the results suggested neuroprotection and neurorestoration activity.129,130”

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.
