Interactions mediated by the cell membrane between inclusions, such as membrane proteins or antimicrobial peptides, play important roles in their biological activity. They also constitute a fascinating challenge for physicists, since they test the boundaries of our understanding of self-assembled lipid membranes, which are remarkable examples of two-dimensional complex fluids. Inclusions can couple to various degrees of freedom of the membrane, resulting in different types of interactions. In…

Membrane-Mediated Interactions Between Protein Inclusions
TLDR
The membrane-mediated interactions originate from perturbation of lipid membranes by the presence of protein inclusions, and have been the subject of intensive research in membrane biophysics.
Size-dependent aggregation of hydrophobic nanoparticles in lipid membranes.
TLDR
It is found that the free energy of dimerization depends strongly on nanoparticle size: the smallest molecules (mimicking C60 fullerene) aggregate only weakly, the largest ones form large three-dimensional aggregates causing major deformations in the host membrane, and the intermediate-sized particles show a tendency to form linear aggregates.
A formula for membrane mediated point particle interactions on near spherical biomembranes
We consider a model of a biomembrane with attached proteins. The membrane is represented by a near spherical continuous surface and attached proteins are described as discrete rigid structures which…
Revealing the Mechanisms of Synergistic Action of Two Magainin Antimicrobial Peptides
TLDR
Detailed dose-response curves, presented here for the first time, show a cooperative behavior for the individual peptides which is much increased when PGLa and magainin are added as equimolar mixture, which can potentially be used to increase the therapeutic window of pharmaceutical formulations.

Membrane-Mediated Inter-Domain Interactions
TLDR
The authors' simulations show that the membrane-mediated inter-domain interaction remains repulsive for the contact angle as large as close to 90°, and the repulsive interaction force between curved domains increases with the domain curvature and hinders the further domain coalescence.
Lipid-mediated protein interaction in membranes.
Interactions between proteins bound to biomembranes.
TLDR
An exact analytic solution is found for the repulsive interaction between two similar circularly symmetric inclusions, which extends over length scales approximately sqrt[kappa/gamma] and contrasts with the membrane-mediated contact attraction for similar inclusions on tensionless membranes.

Aggregation and vesiculation of membrane proteins by curvature-mediated interactions
Membrane remodelling plays an important role in cellular tasks such as endocytosis, vesiculation and protein sorting, and in the biogenesis of organelles such as the endoplasmic reticulum or the…
Membrane-Mediated Interaction between Strongly Anisotropic Protein Scaffolds
TLDR
This work investigated the membrane mediated interaction between proteins or protein oligomers representing membrane scaffolds with strongly anisotropic curvature and addressed, quantitatively, a specific case of the scaffold geometrical parameters characterizing BAR domains, which are crucial for membrane shaping in endocytosis.
Coupling between Inclusions and Membranes at the Nanoscale.
TLDR
This work combines small-angle x-ray scattering data and a complete elastic model to measure the slope for the model gramicidin channel and shows that it is surprisingly steep in two membrane systems with very different elastic properties.
Membrane perturbations induced by integral proteins: Role of conformational restrictions of the lipid chains
TLDR
It is shown that conformational restrictions of the lipid chains in the vicinity of the wall modify the microelastic behavior of lipid membranes, and the wall induces an increase in the tilt modulus and a spontaneous tilt.
Membrane-protein interactions in a generic coarse-grained model for lipid bilayers.
TLDR
The simulations show that the lipid-mediated interactions are governed by five competing factors: direct interactions; cholesterol-induced depletion interactions; lipid bridging; lipid packing; and a smooth long-range contribution.
