How do lipid bilayer components move?
How do lipid bilayer components move? One of the tenets of the Fluid-Mosaic membrane model is that the components of the bilayers are free to move. Before describing the differences between lipid and protein [...]
Why are membrane lipids asymmetrical?
Why are membrane lipids asymmetrical? The human red blood cell is functionally specialized for transporting oxygen. In order to maximize oxygen capacity, it has no nucleus or organelles, consisting primarily of plasma membrane and [...]
How is clathrin recruited to the plasma membrane?
How is clathrin recruited to the plasma membrane? Clathrin-mediated endocytosis is triggered by phosphatidylinositol-4,5-bisphosphate (PIP2) accumulation within the plasma membrane. PIP2 accumulates as a result of phosphoinositide catalysis by the lipid kinases, phosphatidylinositol-4-kinase (PI4K) [...]
What is clathrin-mediated endocytosis?
What is clathrin-mediated endocytosis? Clathrin-mediated endocytosis (CME) is a vesicular transport event that facilitates the internalization and recycling of receptors engaged in a variety of processes, including signal transduction (G-protein and tyrosine kinase receptors), [...]

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.
