Efficient 5-OP-RU-Induced Enrichment of Mucosa-Associated Invariant T Cells in the Murine Lung Does Not Enhance Control of Aerosol Mycobacterium tuberculosis Infection.

abstract：:In vitro, Clostridium perfringens enterotoxin (CPE) binds to human ileal epithelium and induces morphological damage concurrently with reduced short-circuit current, transepithelial resistance, and net water absorption. CPE also binds to the human colon in vitro but causes only slight morphological and transport chang...
