Vibrio cholerae, the etiological agent of cholera, colonizes the small intestine, produces an enterotoxin and causes acute inflammatory response at intestinal epithelial cell surface. Pretreatment of intestinal epithelial cells with quercetin reduces the level of V cholerae induced IL-8 in dose and time dependent manner as determined by ELISA and RT-PCR. Immunofluorescence studies showed that quercetin suppresses the translocation of p50 subunit of NF-kappa B. In vivo, quercetin administration produced a significant reduction of neutrophil infiltration in the intestinal epithelial layer of suckling mouse. Taken together, quercetin could inhibit the V cholerae induced inflammation and may therefore find use in management of V cholerae induced pathogenesis. (C) 2012 Institut Pasteur.
