Mechanism of Inosine from Lactiplantibacillus plantarum MWFLp-182-Treated Mice Model in Alleviating D-Galactose-Induced HT-22 Cell Injury via Oxidative and Inflammatory Pathways.

ABSTRACT: Gut microbial metabolites play a crucial role in modulating cognitive function. In a previous animal study, oral administration of Lactiplantibacillus plantarum MWFLp-182 (L. plantarum MWFLp-182) significantly increased inosine levels in both the serum and feces of D-galactose (D-gal)-induced mice, which was accompanied by improved cognitive performance. Building on this finding, we further investigated the neuroprotective mechanisms of inosine derived from L. plantarum MWFLp-182 in alleviating D-gal-induced neuronal damage in HT-22 cells. Reverse transcription-quantitative PCR (RT-qPCR) was used to analyze the addition of inosine (250 μg/mL, 500 μg/mL), which considerably reduces oxidative stress induced by D-gal (20 mg/mL), on the regulation of mRNA expression of the
