A bioengineered human urothelial organoid model reveals the urine-urothelium interplay in tissue resilience and UPEC recurrence in urinary tract infections

Gauri Paduthol, Mikhail Nikolaev, Kunal Sharma…·John D. McKinney

The paper develops a human urothelial organoid model to study urine-urothelium interactions in UTI resilience and UPEC recurrence, finding that high-solute urine weakens tissue and promotes CWD UPEC formation.

Lysosomal activation in bladder epithelium enhances intracellular antibiotic clearance of uropathogenic Escherichia coli

Kathrin Tomasek, Kristina Skurvydaite, Gauri Paduthol…·John D. McKinney

This study shows that OM-89 enhances lysosomal activity in bladder epithelial cells, improving antibiotic efficacy against UPEC and reducing bacterial regrowth.
