Breast Cancer Res
. 2023 May;
25(1):52.
PMID: 37147680
Background: In light of the growing appreciation for the role of collective cell motility in metastasis, a deeper understanding of the underlying signaling pathways will be critical to translating these...

Cell Syst
. 2023 Feb;
14(3):196-209.e6.
PMID: 36827986
Maintaining persistent migration in complex environments is critical for neutrophils to reach infection sites. Neutrophils avoid getting trapped, even when obstacles split their front into multiple leading edges. How they...

Brunetti R, Kockelkoren G, Raghavan P, Bell G, Britain D, Puri N, et al.
J Cell Biol
. 2021 Dec;
221(2).
PMID: 34964841
To control their movement, cells need to coordinate actin assembly with the geometric features of their substrate. Here, we uncover a role for the actin regulator WASP in the 3D...

Bell G, Rincon E, Akdogan E, Collins S
Nat Commun
. 2021 Nov;
12(1):6148.
PMID: 34785668
During chemotaxis, neutrophils use cell surface G Protein Coupled Receptors to detect chemoattractant gradients. The downstream signaling system is wired with multiple feedback loops that amplify weak inputs and promote...

Nat Commun
. 2021 Nov;
12(1):6619.
PMID: 34785640
To migrate efficiently to target locations, cells must integrate receptor inputs while maintaining polarity: a distinct front that leads and a rear that follows. Here we investigate what is necessary...

Bell G, Natwick D, Collins S
Methods Mol Biol
. 2018 Aug;
1821:71-85.
PMID: 30062406
Neutrophils are key early responders in the innate immune response that use chemotaxis, the directed migration along chemical gradients, to reach sites of infection or inflammation. This process requires integrating...

Dev Cell
. 2018 Jul;
46(1):1-3.
PMID: 29974859
The physicist Edward Purcell wrote in 1977 about mechanisms that cells could use to propel themselves in a low Reynolds number environment. Reporting in Developmental Cell, O'Neill et al. (2018)...

. 2017 Dec;
13(3):035002.
PMID: 29271355
The highly diverse and changeable body patterns of cephalopods require the production of whiteness of varying degrees of brightness for their large repertoire of communication and camouflage behaviors. Leucophores are...

PMID: 24741712
A major component of cephalopod adaptive camouflage behavior has rarely been studied: their ability to change the three-dimensionality of their skin by morphing their malleable dermal papillae. Recent work has...
