New investigation results, 'Hfq negatively regulates type III secretion in EHEC and several other pathogens,' are detailed in a study published in Molecular Microbiology. "Hfq is a conserved RNA-binding protein that regulates diverse cellular processes through post-transcriptional control of gene expression, often by functioning as a chaperone for regulatory sRNAs. Here, we explored the role of Hfq in enterohaemorrhagic Escherichia coli (EHEC), a group of non-invasive intestinal pathogens," scientists in the United States report (see also Life Sciences).
"EHEC virulence is dependent on a Type III secretion system encoded in the LEE pathogenicity island. The ...
