Universal Casimir attraction between filaments at the cell scale
Benjamin Spreng, Hélène Berthoumieux, Astrid Lambrecht +3
The electromagnetic Casimir interaction between dielectric objects immersed in salted water includes a universal contribution that is not screened by the solvent and therefore long…
A universal attractive interaction between filaments at the cell scale
Anne-Florence Bitbol, Hélène Berthoumieux, Benjamin Spreng +2
Actin filaments and microtubules both often form bundles of parallel filaments within cells. Here, we shed light on a universal attractive interaction between two such parallel fil…
Hydrodynamic flow and concentration gradients in the gut enhance neutral bacterial diversity
Darka Labavić, Claude Loverdo, Anne-Florence Bitbol
The gut microbiota features important genetic diversity, and the specific spatial features of the gut may shape evolution within this environment. We investigate the fixation proba…
Mitochondrial cristae modeled as an out-of-equilibrium membrane driven by a proton field
Nirbhay Patil, Stéphanie Bonneau, Fréderic Joubert +2
As the places where most of the fuel of the cell, namely ATP, is synthesized, mitochondria are crucial organelles in eukaryotic cells. The shape of the invaginations of the mitocho…
Membrane-mediated interactions
Anne-Florence Bitbol, Doru Constantin, Jean-Baptiste Fournier
Interactions mediated by the cell membrane between inclusions, such as membrane proteins or antimicrobial peptides, play important roles in their biological activity. They also con…
pH Sensing by Lipids in Membranes: The Fundamentals of pH-driven Migration, Polarization and Deformations of Lipid Bilayer Assemblies
Miglena I. Angelova, Anne-Florence Bitbol, Michel Seigneuret +6
Most biological molecules contain acido-basic groups that modulate their structure and interactions. A consequence is that pH gradients, local heterogeneities and dynamic variation…
Quantifying the impact of a periodic presence of antimicrobial on resistance evolution in a homogeneous microbial population of fixed size
Loïc Marrec, Anne-Florence Bitbol
The evolution of antimicrobial resistance generally occurs in an environment where antimicrobial concentration is variable, which has dramatic consequences on the microorganisms' f…
Inferring interaction partners from protein sequences
Anne-Florence Bitbol, Robert S. Dwyer, Lucy J. Colwell +1
Specific protein-protein interactions are crucial in the cell, both to ensure the formation and stability of multi-protein complexes, and to enable signal transduction in various p…
Fundamental constraints on the abundances of chemotaxis proteins
Anne-Florence Bitbol, Ned S. Wingreen
Flagellated bacteria, such as Escherichia coli, perform directed motion in gradients of concentration of attractants and repellents in a process called chemotaxis. The E. coli chem…
