Quantitative model and physical mechanisms of iRBC membrane curling during egress of malaria parasites

G. Nick, A. Parmeggiani, A. V. KAJAVA

The paper develops a biophysical model to explain the energy mechanisms behind iRBC membrane curling during malaria parasite egress, showing that lateral lipid diffusion, not viscosity, drives the process.

Chromatin structure from high resolution microscopy: scaling laws and microphase separation

L. Remini, M. Segers, J. Palmeri, J.-C. Walter, A. Parmeggiani, E. Carlon

The paper analyzes high-resolution microscopy data to identify two distinct chromatin conformational phases in human Chr.21, showing different scaling behaviors and implications for chromatin structure.

Relaxation time asymmetry in stator dynamics of the bacterial flagellar motor

R. Perez-Carrasco, M.-J. Franco-Onate, J.-C. Walter, J. Dorignac, F. Geniet, J. Palmeri, A. Parmeggiani, N.-O. Walliser, A. L. Nord

The paper investigates stator dynamics in bacterial flagellar motors, revealing a stoichiometry-dependent asymmetry in remodeling kinetics that is best explained by a two-state catch-bond mechanism.

ATP-driven separation of liquid phase condensates in bacteria

B. Guilhas, J.-C. Walter, J. Rech, G. David, N. Walliser, J. Palmeri, C. Mathieu-Demaziere, A. Parmeggiani, J.-Y. Bouet, A. Le Gall, M. Nollmann

The paper investigates how ATP-driven mechanisms organize liquid phase condensates in bacteria, showing that ParA prevents their fusion and enables segregation.

Macrophage plasticity is Rac signalling and MMP9 dependant

J. TRAVNICKOVA, S. Nhim, N. ABDELLAOUI, F. DJOUAD, M. NGUYEN-CHI, A. PARMEGGIANI, K. KISSA

This study shows macrophages adapt their migratory shapes in zebrafish embryos, and this plasticity depends on Rac signalling and MMP9, which are crucial for ECM degradation and HSPC mobilisation.
