Keller, S. L., Bezrukov, A. M., Gruner, S. M., Tate, M. W., Vodyanoy, I.
With few exceptions (1-3), membrane lipids are usually regarded as a kind of filler or passive solvent for membrane proteins. Yet, cells exquisitely control membrane composition. Many phospholipids...

Geometrical aspects of the frustration in the cubic phases of lyotropic liquid crystals.
Anderson, D M, Gruner, S M, Leibler, S
Bicontinuous cubic phases, composed of bilayers arranged in the geometries of periodic minimal surfaces, are found in a variety of different lipid/water systems. It has been suggested recently that...
Unusual lipid structures selectively reduce the toxicity of amphotericin B.
Janoff, A S, Boni, L T, Popescu, M C, Minchey, S R, Cullis, P R, Madden, T D, ...
Ribbon-like structures result when amphotericin B interacts with lipid in an aqueous environment. At high ratios of amphotericin to lipid these structures, which are lipid-stabilized amphotericin...
Intrinsic curvature hypothesis for biomembrane lipid composition: a role for nonbilayer lipids.
A rationale is presented for the mix of "bilayer" and "nonbilayer" lipids, which occurs in biomembranes. A theory for the L alpha-HII phase transition and experimental tests of the theory are...
