Research publication: Roles of Interleaflet Coupling and Hydrophobic Mismatch in Lipid Membrane Phase-Separation Kinetics

At last year’s Biophysical Society 2015 meeting, Peter Olmsted and I met Philip Fowler, who at the time worked in Mark Sansom‘s group (he now works in the Nuffield Department of Medicine at Oxford). I had noticed a signal in their lipid bilayer simulations that looked like a two-step asymmetry/symmetry transition we had studied theoretically. Understanding how constituents of a lipid bilayer interact and self-organise is key to the biology of the cell membrane, as well as to applications of synthetic lipid bilayer membranes.

It has been a pleasure to work with Phil and Mark over the past year as we have looked closely into the symmetry and asymmetry of phase-separating bilayers, using a raft (geddit?) of new simulations expertly constructed and analysed by Phil. A joint paper is out now in JACS, linking the kinetics of lipid bilayer phases to a theoretical model of competing inter-leaflet coupling effects. Check it out!
