Research Interests

Our laboratory is interested in signal transduction and the regulation of gene expression in prokaryotes. In particular, we are studying the two-component regulatory system EnvZ/OmpR that regulates the expression of outer membrane proteins as well as many other genes. Our present work focuses on how OmpR activates genes required for systemic infection (located on Salmonella pathogenicity island 2) in Salmonella enterica.

The Kenney Lab’s research was recently featured in an article exploring the bacterial molecular switch between virulence or dormancy, Salmonella Lifestyle Choices. Members of her lab have discovered that the bacterial protein SsrB is the molecular switch for determining whether Salmonella infections become acute and virulent, or remain in a dormant carrier state.

The study is published in eLife (Desai et al., The horizontally-acquired response regulator SsrB drives a Salmonella lifestyle switch by relieving biofilm silencing, February 2, 2016, eLife 2016; 5: e10747, doi: 10.7554/eLife.10747). Read full article.
