| Members of the genus Listeria provide a model for defining host responses to invasive foodborne enteropathogens. Active translocation of Listeria monocytogenes across the gut epithelial barrier is mediated by interaction of bacterial internalin (InlA) and its species-specific host receptor, E-cadherin, whereas translocation across Peyer’s patches through M-cells is InlA independent. To define microbial determinants and molecular correlates of the host response to translocation via these two routes, we colonized germ-free transgenic mice expressing the human enterocyte-associated E-cadherin receptor with wildtype (WT) or mutant L. monocytogenes strains, or its nonpathogenic noninvasive relative Listeria innocua, or with Bacteroides thetaiotaomicron, a... |

| Helicobacter pylori infection of the stomach elicits a vigorous but ineffective host immune and inflammatory response, resulting in persistence of the bacterium for the life of the host. We have reported that in macrophages, H. pylori up-regulates inducible NO synthase (iNOS) and antimicrobial NO production, but in parallel there is induction of arginase 11, generating ornithine, and of ornithine decarboxylase (ODC), generating polyamines. Spermine, in particular, has been shown to restrain immune response in activated macrophages by inhibiting proinflammatory gene expression. We hypothesized that spermine could prevent the antimicrobial effects of NO by inhibiting iNOS in macrophages activated by H. pylori. Spermine did not affect the upregulation of iNOS... |
