Physical mechanisms of red blood cell splenic filtration

A. Moreau, F. Yaya, H. Lu, A. Surendranath, A. Charrier, B. Dehapiot, E. Helfer, A. Viallat, Z. Peng

This paper investigates how red blood cells pass through narrow splenic slits using multiscale modeling, live imaging, and microfluidic experiments, finding that cells deform into two tether-connected spheres and unfold their cytoskeleton to pass through.

Enhanced cell viscosity: a new phenotype associated withlamin A/C alterations

C. Jebane, A.-A. Varlet, M. Karnat, L. M. Hernandez-Cedillo, A. Lecchi, F. Bedu, C. Desgrouas, C. Vigouroux, M.-C. Vantyghem, A. Viallat, J.-F. Rupprecht, E. Helfer, C. Badens

This study quantifies whole cell mechanical changes caused by lamin A/C alterations using microfluidic experiments, revealing increased long-time viscosity as a potential diagnostic marker.

Longitudinal to transverse metachronal wave transitions in an in-vitro model of ciliated bronchial epithelium

O. Mesdjian, C. Wang, S. Gsell, U. D'Ortona, J. Favier, A. Viallat, E. Loiseau

The paper shows that the direction of metachronal waves in ciliated epithelium depends on mucus transport efficiency, with longitudinal waves maximizing mucus transport and transverse waves minimizing energy dissipation.

Hydrodynamic model of directional ciliary-beat organization in human airways

S. Gsell, E. Loiseau, U. D'Ortona, A. Viallat, J. Favier

The paper develops a hydrodynamic model to explain directional ciliary-beat organization in human airways, showing it reproduces mucus swirls and predicts flow transitions based on ciliary density and mucus viscosity.

Active mucus-cilia hydrodynamic coupling drives self-organisation of human bronchial epithelium

E. Loiseau, S. Gsell, A. Nommick, C. Jomard, D. Gras, P. Chanez, U. D'Ortona, L. Kodjabachian, J. Favier, A. Viallat

The paper shows that mucus-cilia hydrodynamic coupling drives self-organisation of human bronchial epithelium during ciliogenesis, leading to macroscopic mucus transport.
