Abstract

significantly alleviated depressive-like behaviors, reducing immobility time by 40%.

  • FLX improved gastrointestinal motility, increasing fecal pellet output by 35%.
  • Serotonin signaling was restored, with a 2.5-fold increase in serotonin levels.
  • Intestinal barrier integrity was enhanced, showing a 60% upregulation of tight junction proteins.
  • Gut microbial diversity increased, with a 30% rise in the Shannon index.
  • The combination of FLX and produced a 65% improvement in gut motility and a 70% reduction in pro-inflammatory cytokines.
  • This combination also achieved an 80% restoration of intestinal barrier function compared to FLX alone.
