Interferon γ Induces Translocation of Commensal Escherichia coli Across Gut Epithelial Cells via a Lipid Raft--Mediated Process

Conclusions: Normally poorly invasive enteric bacteria may, in situations of inflammatory stress, exploit lipid raft-mediated transcytotic pathways to cross the intestinal epithelium, and these effects may precede cytokine-induced disruption of tight junctions.
