Investigates the mechanism of Bifidobacterium bifidum enhancing the intestinal barrier in inflammatory bowel disease, suggesting beneficial microbe-host interactions.
Key Points
To explore how Bifidobacterium bifidum upregulates the intestinal epithelial tight junction barrier.
Used in vitro models (Caco-2 monolayers) and in vivo models (live mice) to study the effects.
Measured occludin gene activity and protein expression levels.
Evaluated the role of TLR-2/TLR-6 receptor complex activation in the process.
