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.

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 ...

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 ...

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 ...

WIREs Systems Biology and Medicine, 2009 AbstractDuring eukaryotic chemotaxis, external chemical gradients guide the crawling motion of cells. This process plays an important role in a large variety of biological systems and has wide ranging medical implications. New experimental techniques including confocal microscopy and microfluidics have advanced our understanding of chemotaxis while ...

Bioavailability of pollutants and chemotaxis [PDF]
Current Opinion in Biotechnology, 2013 The exposure of bacteria to pollutants induces frequently chemoattraction or chemorepellent reactions. Recent research suggests that the capacity to degrade a toxic compound has co-evolved in some bacteria with the capacity to chemotactically react to it.

Psoriasis and Leukocyte Chemotaxis.
Journal of Investigative Dermatology, 1987 Transepidermal migration of leukocytes, with resultant formation of microscopic or macroscopic sterile subcorneal pustules is a phenomenon characteristically noted in psoriasis and related sterile pustular dermatoses. It is natural to assume the presence of potent neutrophil chemotactic substances in the subcorneal portion of the lesional epidermis ...

“TORCing” Neutrophil Chemotaxis [PDF]
Developmental Cell, 2010 During cell migration, chemoattractant-induced signaling pathways determine the direction of movement by controlling the spatiotemporal dynamics of cytoskeletal components. In this issue of Developmental Cell, Liu et al. report that the target of rapamycin complex 2 (TORC2) controls cell polarity and chemotaxis through regulation of both F-actin and ...

The Journal of Cell Biology, 2007 A cell polarity switch controls whether cells rush toward an attractive chemical or shift into reverse when they encounter something repulsive, according to Keizer-Gunnink et al. on page 579. They show that the status of phospholipase C (PLC) sets up the polarity axis for directional movement.
