Homeostatic interplay between bacterial cell-cell signaling and iron in virulence

Hazan, R.; He, J.; Xiao, G.; Dekimpe, V.; Apidianakis, Yiorgos; Lesic, B.; Astrakas, C.; Déziel, Eric; Lépine, F.; Rahme, L. G. (2010)

Pathogenic bacteria use interconnected multi-layered regulatory networks, such as quorum sensing (QS) networks to sense and respond to environmental cues and external and internal bacterial cell signals, and thereby adapt ...

The pathogenic properties of a novel and conserved gene product, KerV, in proteobacteria

An, D.; Apidianakis, Yiorgos; Boechat, A. L.; Baldini, R. L.; Goumnerov, B. C.; Rahme, L. G. (2009)

Identification of novel virulence factors is essential for understanding bacterial pathogenesis and designing antibacterial strategies. In this study, we uncover such a factor, termed KerV, in Proteobacteria. Experiments ...

A quorum sensing regulated small volatile molecule reduces acute virulence and promotes chronic infection phenotypes

Kesarwani, M.; Hazan, R.; He, J.; Que, Y.; Apidianakis, Yiorgos; Lesic, B.; Xiao, G.; Dekimpe, V.; Milot, S.; Déziel, Eric; Lépine, F.; Rahme, L. G. (2011)

A significant number of environmental microorganisms can cause serious, even fatal, acute and chronic infections in humans. The severity and outcome of each type of infection depends on the expression of specific bacterial ...

The structure of a ferrous heme-nitro species in the binuclear heme a3/CuB center of ba3-cytochrome c oxidase as determined by resonance Raman spectroscopy

Loullis, Andreas; Noor, M. R.; Soulimane, T.; Pinakoulaki, Eftychia (2015)

Members of the cytochrome c oxidase family exhibit nitrite reductase activity. In this work, we have characterized a ferrous heme a3-nitro species in ba3-oxidase by resonance Raman spectroscopy. This provides the first ...
