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 ...

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 ...

Biomixing by chemotaxis and efficiency of biological reactions: the critical reaction case
, 2012 Many phenomena in biology involve both reactions and chemotaxis. These processes can clearly influence each other, and chemotaxis can play an important role in sustaining and speeding up the reaction.

Enhanced Diffusion and Chemotaxis at the Nanoscale. [PDF]
Accounts of Chemical Research, 2018 Enzymes have been recently proposed to have mechanical activity associated with their chemical activity. In a number of recent studies, it has been reported that enzymes undergo enhanced diffusion in the presence of their corresponding substrate when ...

Supracellular contraction at the rear of neural crest cell groups drives collective chemotaxis
Science, 2018 Supracellular cable drives collective cell movement Neural crest cells migrate far and wide through a vertebrate embryo during development. Shellard et al. used Xenopus and zebrafish embryos to study how these clumps of mesenchymal cells migrate (see the

Fractional Chemotaxis Diffusion Equations [PDF]
, 2010 We introduce mesoscopic and macroscopic model equations of chemotaxis with anomalous subdiffusion for modelling chemically directed transport of biological organisms in changing chemical environments with diffusion hindered by traps or macro-molecular ...

Mechanisms involved in human eosinophil chemotaxis induced by the newly cloned C-C chemokine eotaxin
Allergology International, 1998 The present study was performed in order to investigate the mechanism(s) involved in eotaxin-induced normal human eosinophil chemotaxis using a 48-well micro-chemotaxis chamber assay.

Perfect and near perfect adaptation in a model of bacterial chemotaxis [PDF]
, 2002 The signaling apparatus mediating bacterial chemotaxis can adapt to a wide range of persistent external stimuli. In many cases, the bacterial activity returns to its pre-stimulus level exactly and this "perfect adaptability" is robust against variations ...

Molecular Plant-Microbe Interactions, 2018 Chemotaxis-mediated response to root exudates, initiated by sensing-specific ligands through methyl-accepting chemotaxis proteins (MCP), is very important for root colonization and beneficial functions of plant-growth-promoting rhizobacteria (PGPR ...
