Escherichia coli are the most common etiological agents of urinary tract infections (UTIs). Uropathogenic E. coli (UPECs) produce specific toxins including the cytotoxic necrotizing factor-1 (CNF1) and the alpha-hemolysin (α-Hly). CNF1 triggers, through Rho protein activation, a specific gene response of host cells, which results in the production for instance of interleukin-8 (IL-8), monocyte chemoattractant...
CNF1 toxin is a virulence factor produced by uropathogenic Escherichia coli. Upon cell binding and introduction into the cytosol, CNF1 deamidates glutamine 63 of RhoA (or 61 of Rac and Cdc42), rendering constitutively active these GTPases. Unexpectedly, we measured in bladder cells a transient CNF1-induced activation of Rho GTPases, maximal for Rac. Deactivation of Rac correlated with the increased...
