Abstract

While glucagon‐like peptide‐1 (GLP‐1) was reported to have a positive impact on Parkinson disease, it is extremely short half‐life greatly hindered its clinical use. In this study, the mouse strain MG 1363‐pMG 36e‐GLP‐1 was engineered to continuously express GLP‐1 to treat Parkinson disease in a 1‐methyl‐4‐phenyl‐1, 2, 3, 6‐tetrahydropyridine (MPTP)‐treated Parkinson disease model. In our study, oral supplementation with MG 1363‐pMG 36e‐GLP‐1 significantly (p < 0.05) reduced MPTP‐induced locomotor impairments, increased tyrosine hydroxylase‐positive neurons, suppressed microglia and astrocyte activation, and down‐regulated expression of several inflammation‐related molecules. In addition, MG 1363‐pMG 36e‐GLP‐1 significantly (p < 0.01) reduced intestinal pathogen Enterobacteriaceae and markedly enhanced the number of probiotic Lactobacillus and Akkermansia. These data suggest that MG 1363‐pMG 36e‐GLP‐1 could be a novel therapeutic means for Parkinson disease. image

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.
