exposed to external chemical gradients. It is exhibited by a wide variety of cell types and …

Fam49/CYRI interacts with Rac1 and locally suppresses protrusions

L Fort, JM Batista, PA Thomason, HJ Spence… - Nature cell …, 2018‏ - nature.com
Actin-based protrusions are reinforced through positive feedback, but it is unclear what

Steering yourself by the bootstraps: how cells create their own gradients for chemotaxis

RH Insall, P Paschke, L Tweedy - Trends in Cell Biology, 2022‏ - cell.com
Chemotaxis, where cell movement is steered by chemical gradients, is a widespread and
essential way of organising cell behaviour. But where do the instructions come from–who …

Self-generated gradients yield exceptionally robust steering cues

L Tweedy, RH Insall - Frontiers in Cell and Developmental Biology, 2020‏ - frontiersin.org
Chemotaxis is a widespread mechanism that allows migrating cells to steer to where they
are needed. Attractant gradients may be imposed by external sources, or self-generated …
