Story summary

Genentech and Oregon Health & Science University (OHSU) researchers report that the virulent Escherichia coli strain uses the bacterial protein NleL to degrade ROCK1 and ROCK2, hindering expulsion of infected cells from the intestinal lining.
The Nature publication shows this mechanism enables gut colonization and suggests virulence-targeted therapies as alternatives to antibiotics.
The findings address antibiotic resistance concerns and imply relevance for chronic gut disorders such as inflammatory bowel disease.
