Autophagy mediates the impact of Porphyromonas gingivalis on short-chain fatty acids metabolism in periodontitis-induced gut dysbiosis.

ABSTRACT: Porphyromonas gingivalis (P. gingivalis), the main pathogen responsible for periodontitis, is linked to systemic disorders via the oral-gut axis. Short-chain fatty acids (SCFAs) are vital for gut health, but their role in P. gingivalis-induced gut disorders remains unclear. This study utilized metabolomics and 16 S rRNA sequencing to explore gut microbiota and SCFAs levels in P. gingivalis-induced periodontitis mouse models. Significant changes were observed in gut, including a reduction in SCFAs-producing bacteria, such as Lactobacillus, Ligilactobacillus, Allobucalum, and a notable decrease in Firmicutes and Actinobacteriota. The intestinal permeability tests and histological analyses revealed that periodontitis led to epithelial inflammation, reduced mucin secretion, and compromised gut
