Sperm chemotaxis in marine invertebrates and mammals
Reproductive and Developmental Medicine, 2017 Sperm respond to multiple chemical factors derived from the eggs and reorient their migratory direction – a process called chemotaxis. The chemotaxis of sperm in marine invertebrates has been established well.

TRPM2 ion channels steer neutrophils towards a source of hydrogen peroxide
Scientific Reports, 2021 Neutrophils must navigate accurately towards pathogens in order to destroy invaders and thus defend our bodies against infection. Here we show that hydrogen peroxide, a potent neutrophil chemoattractant, guides chemotaxis by activating calcium-permeable ...

A new class of protein sensor links spirochete pleomorphism, persistence, and chemotaxis
mBio, 2023 Pathogenic spirochetes can alter their morphologies and behaviors to infect and survive within their hosts. Previous reports demonstrate that the formation of the so-called “round bodies” and biofilms, and chemotaxis are involved in spirochete ...

Bacterial chemotaxis: a way forward to aromatic compounds biodegradation
Environmental Sciences Europe, 2020 Worldwide industrial development has released hazardous polycyclic aromatic compounds into the environment. These pollutants need to be removed to improve the quality of the environment.

Chemotaxis and autochemotaxis of self-propelling droplet swimmers [PDF]
Proceedings of the National Academy of Sciences of the United States of America, 2016 Significance Statement Chemotaxis and autochemotaxis are key mechanisms in the dynamics of microorganisms, e.g., in the acquisition of nutrients and in the communication between individuals, as well as influencing their collective behavior.

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).

Journal of Lipid Research, 2013 Monocyte chemoattractant protein-1 (MCP-1)-induced monocyte chemotaxis is a major event in inflammatory disease. Our prior studies have demonstrated that MCP-1-dependent chemotaxis requires release of arachidonic acid (AA) by activated cytosolic ...

Phoresis and Enhanced Diffusion Compete in Enzyme Chemotaxis. [PDF]
Nano letters (Print), 2018 Chemotaxis of enzymes in response to gradients in the concentration of their substrate has been widely reported in recent experiments, but a basic understanding of the process is still lacking. Here, we develop a microscopic theory for chemotaxis that is

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 ...
