Polygala tenuifolia polysaccharide changes metabolism and gut bacteria in aging mice

Updated

Abstract

Polygala tenuifolia polysaccharide (PTP) significantly improved the disruption of metabolites and gut microbiota associated with Alzheimer's disease.

  • Nineteen metabolites, including leukotriene B4 and vanylglycol, were significantly reduced with PTP treatment, while two metabolites were elevated.
  • PTP treatment was significantly enriched in metabolic pathways related to Sphingolipid, Glycerophospholipid, Tyrosine, and Arachidonic acid metabolism.
  • Analysis of gut bacteria showed that PTP treatment significantly increased the relative abundance of Alistipes and specific Lachnospiraceae groups.
  • Significant changes in gut microbiota were closely associated with the observed differences in endogenous metabolites.
