Gut-brain axis metabolites in early AD pathogenesis

PARTIALLY ADDRESSED

Emerging evidence suggests gut microbial metabolites (SCFAs, TMAO, tryptophan metabolites) may influence amyloid-beta aggregation and neuroinflammation years before clinical symptoms, but causal mechanisms are poorly defined.
