Directed collective motion of bacteria under channel confinement

H Wioland, E Lushi, RE Goldstein - New Journal of Physics, 2016 - iopscience.iop.org
Dense suspensions of swimming bacteria are known to exhibit collective behaviour arising
from the interplay of steric and hydrodynamic interactions. Unconfined suspensions exhibit …

Confinement stabilizes a bacterial suspension into a spiral vortex

H Wioland, FG Woodhouse, J Dunkel, JO Kessler… - Physical review …, 2013 - APS
Confining surfaces play crucial roles in dynamics, transport, and order in many physical
systems, but their effects on active matter, a broad class of dynamically self-organizing systems, …

[HTML][HTML] Structural basis of rapid actin dynamics in the evolutionarily divergent Leishmania parasite

T Kotila, H Wioland, M Selvaraj, K Kogan… - Nature …, 2022 - nature.com
Actin polymerization generates forces for cellular processes throughout the eukaryotic kingdom,
but our understanding of the ‘ancient’ actin turnover machineries is limited. We show that…

Fluid flows created by swimming bacteria drive self-organization in confined suspensions

E Lushi, H Wioland… - Proceedings of the …, 2014 - National Acad Sciences
Concentrated suspensions of swimming microorganisms and other forms of active matter are
known to display complex, self-organized spatiotemporal patterns on scales that are large …

[HTML][HTML] Ferromagnetic and antiferromagnetic order in bacterial vortex lattices

H Wioland, FG Woodhouse, J Dunkel, RE Goldstein - Nature physics, 2016 - nature.com
Despite their inherently non-equilibrium nature 1 , living systems can self-organize in highly
ordered collective states 2 , 3 that share striking similarities with the thermodynamic …

[PDF][PDF] ADF/cofilin accelerates actin dynamics by severing filaments and promoting their depolymerization at both ends

H Wioland, B Guichard, Y Senju, S Myram… - Current Biology, 2017 - cell.com
Actin-depolymerizing factor (ADF)/cofilins contribute to cytoskeletal dynamics by promoting
rapid actin filament disassembly. In the classical view, ADF/cofilin sever filaments, and …

Celebrating 20 years of live single-actin-filament studies with five golden rules

H Wioland, A Jégou… - Proceedings of the …, 2022 - National Acad Sciences
The precise assembly and disassembly of actin filaments is required for several cellular
processes, and their regulation has been scrutinized for decades. Twenty years ago, a handful …

[HTML][HTML] Oxidation of F-actin controls the terminal steps of cytokinesis

S Frémont, H Hammich, J Bai, H Wioland… - Nature …, 2017 - nature.com
Cytokinetic abscission, the terminal step of cell division, crucially depends on the local
constriction of ESCRT-III helices after cytoskeleton disassembly. While the microtubules of the …

[HTML][HTML] Mechanism of synergistic actin filament pointed end depolymerization by cyclase-associated protein and cofilin

T Kotila, H Wioland, G Enkavi, K Kogan… - Nature …, 2019 - nature.com
The ability of cells to generate forces through actin filament turnover was an early adaptation
in evolution. While much is known about how actin filaments grow, mechanisms of their …

Torsional stress generated by ADF/cofilin on cross-linked actin filaments boosts their severing

H Wioland, A Jegou… - Proceedings of the …, 2019 - National Acad Sciences
Proteins of the actin depolymerizing factor (ADF)/cofilin family are the central regulators of
actin filament disassembly. A key function of ADF/cofilin is to sever actin filaments. However, …
