Overview

Observational study reveals that high gingival proteolytic activity correlates with specific microbes and inflammatory proteins in periodontitis, indicating potential for improved risk stratification.

Key Points

To evaluate proteolytic activity in gingival crevicular fluid in relation to clinical disease progression risk, microbial composition, and the host proteome in periodontitis.
Collected gingival crevicular fluid from 109 patients with periodontitis and stratified them into high and low proteolytic activity groups using a fluorescent substrate assay.
Profiled the subgingival microbiome using 16S rRNA gene sequencing and characterized the host proteome using mass spectrometry.
Classified 41 of 42 patients in the high proteolytic activity group as clinically high risk for disease progression, whereas the low-activity group comprised both low- and high-risk individuals.
Observed greater microbial diversity and enrichment of proteolytic pathogens (Fusobacterium nucleatum, Porphyromonas gingivalis, and Treponema denticola) in high-activity samples.
Identified 235 differentially expressed host proteins, with high-activity samples enriched in inflammatory and neutrophil-mediated immunity markers, while low-activity samples were enriched in tissue-protective protease inhibitors.
