Cure8 research brief
This paper links specific features of the gut bacterial flagellome to TLR5-driven immune activation and reports a disease-associated shift in flagellin profiles in Crohn’s disease and ulcerative colitis, suggesting potential microbiome markers relevant to IBD inflammation.
Researchers (microbiome, immunology), translational clinicians, and informed patients following microbiome biomarker research.
This study describes FlaPro, a computational pipeline that identifies and functionally annotates bacterial flagellins in human gut microbiome data by predicting their ability to bind and stimulate Toll-like receptor 5 (TLR5).
Using FlaPro on an IBD multi-omics cohort, the authors report lower flagellome diversity and a shift toward a higher proportion of TLR5-stimulatory (versus silent) flagellins in both Crohn’s disease and ulcerative colitis at genomic and transcriptional levels.
The workflow and code are openly available from the authors’ GitHub repository, enabling other researchers to apply the method to additional cohorts.
Results are based on computational classification (FlaPro) applied to multi-omics cohort data; predictions are model-derived and require further experimental validation and independent replication.

This study suggests machine learning of stool microbiome data could eventually help distinguish IBD (especially Crohn’s) from healthy people and some other bowel or systemic conditions.
Researchers are exploring circRNAs as new molecular players in IBD inflammation; that could lead to future biomarker tests or novel treatments targeting immune pathways relevant to Crohn’s disease and ulcerative colitis.
Genetic ancestry can influence IBD risk and disease course, and most prior studies focused on European populations.
