Biliverdin targeting TcdB-DRBD inhibits Clostridioides difficile virulence and restores gut microbiota in Mongolian gerbils (Meriones unguiculatus)
This study identified biliverdin (BV) as a promising natural small-molecule therapeutic for Clostridioides difficile infection (CDI). Through AI-assisted screening and molecular docking, BV showed strong binding affinities to all TcdB variants. In vitro, BV suppressed TcdB-induced cytotoxicity without affecting C. difficile growth. In Mongolian gerbils, BV encapsulated in intestinal epithelial cell-derived extracellular vesicles (I-EVs) improved survival, reduced TcdB load, alleviated intestinal lesions, and restored gut microbiota balance by increasing beneficial Firmicutes and short-chain fatty acid levels. These findings highlight BV's potential for clinical translation in CDI treatment.

A comparative analysis of BV against conventional antibiotics, highlighting its unique advantages in preserving gut health.
Case Study: Biliverdin in Mongolian Gerbil CDI Model
Summary: Encapsulating Biliverdin in intestinal epithelial cell-derived extracellular vesicles (I-EVs) significantly improved outcomes in a Mongolian gerbil model of C. difficile infection.
Challenge: CDI leads to severe symptoms, high recurrence, and gut microbiota dysbiosis, complicated by antibiotic side effects.
Solution: I-EV encapsulated BV delivered directly to the gut, targeting TcdB and restoring gut health.
Results: Significantly recovered body weight, enhanced survival rate, reduced TcdB load, alleviated intestinal lesions, and restored gut microbiota with increased beneficial Firmicutes and SCFAs.
