Lactobacillus reuteri-derived γ-amino butyric acid alleviates MPTP-induced Parkinson's disease through inhibiting ferroptosis via the AKT-GSK3β-GPX4 axis.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Parkinson's disease (PD) is a debilitating neurological disorder characterized by motor dysfunction, which has been associated with alterations in the gut microbiota. Lactobacillus reuteri (L. reuteri), a safe and versatile probiotic, exhibits potent immunomodulatory functions and neuroprotective effects. However, the extent and mechanisms by which L. reuteri mitigates PD remain unclear. Here, we demonstrated that L. reuteri significantly alleviated MPTP-induced PD in mice. Importantly, we found that the protective effects of L. reuteri are mediated by its bioactive metabolites rather than the bacteria themselves. Specifically, L. reuteri elevated the levels of γ-aminobutyric acid (GABA). Administration of GABA to mice mitigated MPTP-induced PD. Mechanistically, GABA inhibited MPTP-induced ferroptosis in neuronal cells through activation of the AKT-GSK3β-GPX4 pathway via the GABA receptor. Collectively, our research elucidates that L. reuteri-derived GABA attenuates MPTP-induced PD by inhibiting ferroptosis via the AKT-GSK3β-GPX4 axis, providing a potential therapeutic approach for the prevention and treatment of PD.
