Mechanical competition promotes selective listening to receptor inputs to resolve directional dilemmas in neutrophil migration

A. Hadjitheodorou, G. R. R. Bell, F. Ellett…·J. A. Theriot

This study shows neutrophils resolve directional dilemmas by committing to one leading edge late in the decision process, influenced by mechanical stretching and receptor inputs.

WASP integrates substrate topology and cell polarity to guide neutrophil migration

R. M. Brunetti, G. Kockelkoren, P. Raghavan…·O. D. Weiner

This study shows WASP integrates substrate topology and cell polarity to guide neutrophil migration by selectively polymerizing actin at the leading edge.

Optogenetic control of receptors reveals distinct roles for actin- and Cdc42-dependent negative signals in chemotactic signal processing

G. R. R. Bell, E. Rincon, E. Akdogan, S. R. Collins

The paper uses optogenetic tools to show that F-actin and Cdc42 provide distinct negative signals that limit Cdc42 activation during chemotaxis.
