Chemotaxis When Bacteria Remember: Drift versus Diffusion [PDF]

, 2011
{\sl Escherichia coli} ({\sl E. coli}) bacteria govern their trajectories by switching between running and tumbling modes as a function of the nutrient concentration they experienced in the past.

Melanoma cells break down LPA to establish local gradients that drive chemotactic dispersal. [PDF]

, 2014
The high mortality of melanoma is caused by rapid spread of cancer cells, which occurs unusually early in tumour evolution. Unlike most solid tumours, thickness rather than cytological markers or differentiation is the best guide to metastatic potential.

Suicidal chemotaxis in bacteria [PDF]

Nature Communications, 2021
AbstractBacteria commonly live in communities on surfaces where steep gradients of antibiotics and other chemical compounds routinely occur. While many species of bacteria can move on surfaces, we know surprisingly little about how such antibiotic gradients affect cell motility.

Chemotaxis in cancer [PDF]

Nature Reviews Cancer, 2011
Chemotaxis of tumour cells and stromal cells in the surrounding microenvironment is an essential component of tumour dissemination during progression and metastasis. This Review summarizes how chemotaxis directs the different behaviours of tumour cells and stromal cells in vivo, how molecular pathways regulate chemotaxis in tumour cells and how ...

Chemotaxis in Childhood [PDF]

Pediatric Research, 1983
Developmental aspects of monocyte and neutrophil chemotaxis were evaluated by the agarose and the Boyden chamber methods. Simultaneous measurements of both the distances and the cell counts were carried out by the agarose method. Before 6 years of age monocyte chemotaxis values, determined by the Boyden chamber method, were significantly lower than ...

Control of human endometrial stromal cell motility by PDGF-BB, HB-EGF and trophoblast-secreted factors [PDF]

, 2013
Human implantation involves extensive tissue remodeling at the fetal-maternal interface. It is becoming increasingly evident that not only trophoblast, but also decidualizing endometrial stromal cells are inherently motile and invasive, and likely ...

Chemotactic properties of Escherichia coli mutants having abnormal Ca2+ content [PDF]

, 1995
The calA, calC, and calD mutants of Escherichia coli are known to be sensitive to Ca2+ (R. N. Brey and B. P. Rosen, J. Bacteriol. 139:824-834, 1979).

Modelling cell movement and chemotaxis pseudopod based feedback [PDF]

, 2011
A computational framework is presented for the simulation of eukaryotic cell migration and chemotaxis. An empirical pattern formation model, based on a system of non-linear reaction-diffusion equations, is approximated on an evolving cell boundary using ...

Chytridiomycosis of marine diatoms : the role of stress physiology and resistance in parasite-host recognition and accumulation of defense molecules [PDF]

, 2017
Little is known about the role of chemotaxis in the location and attachment of chytrid zoospores to potential diatom hosts. Hypothesizing that environmental stress parameters affect parasite-host recognition, four chytrid-diatom tandem cultures ...

THE CHEMOSUPPRESSION OF CHEMOTAXIS [PDF]

The Journal of Experimental Medicine, 1966
The effects of various drugs on chemotaxis of polymorphonuclear leukocytes (PMN's) in vitro and in vivo have been studied. Response of rabbit PMN's in vitro to the chemotactic factor of rabbit serum, consisting of an activated protein-protein complex of the fifth and sixth (and probably seventh) components of complement (C'), is suppressed by ...
