Eukaryotic chemotaxis [PDF]

open access: yesWIREs 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 ...

The Azospirillum brasilense Core Chemotaxis Proteins CheA1 and CheA4 Link Chemotaxis Signaling with Nitrogen Metabolism

open access: yesmSystems, 2021
Bacterial chemotaxis affords motile bacteria the ability to navigate the environment to locate niches for growth and survival. At the molecular level, chemotaxis depends on chemoreceptor signaling arrays that interact with cytoplasmic proteins to control

Bayes-Optimal Chemotaxis [PDF]

open access: yesNeural Computation, 2011
Chemotaxis plays a crucial role in many biological processes, including nervous system development. However, fundamental physical constraints limit the ability of a small sensing device such as a cell or growth cone to detect an external chemical gradient.

Simplified Cell Magnetic Isolation Assisted SC2 Chip to Realize “Sample in and Chemotaxis Out”: Validated by Healthy and T2DM Patients’ Neutrophils

open access: yesMicromachines, 2022
Neutrophil migration in tissues critically regulates the human immune response and can either play a protective role in host defense or cause health problems. Microfluidic chips are increasingly applied to study neutrophil migration, attributing to their

The Novel Functions of the PLC/PKC/PKD Signaling Axis in G Protein-Coupled Receptor-Mediated Chemotaxis of Neutrophils

open access: yesJournal of Immunology Research, 2015
Chemotaxis, a directional cell migration guided by extracellular chemoattractant gradients, plays an essential role in the recruitment of neutrophils to sites of inflammation.

Distinct Chemotaxis Protein Paralogs Assemble into Chemoreceptor Signaling Arrays To Coordinate Signaling Output

open access: yesmBio, 2019
Most chemotactic motile bacteria possess multiple chemotaxis signaling systems, the functions of which are not well characterized. Chemotaxis signaling is initiated by chemoreceptors that assemble as large arrays, together with chemotaxis coupling ...

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

open access: yes, 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 ...

Sperm chemotaxis in marine invertebrates and mammals

open access: yesReproductive 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

open access: yesScientific 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 ...

Drug targeting to decrease cardiotoxicity – determination of the cytotoxic effect of GnRH-based conjugates containing doxorubicin, daunorubicin and methotrexate on human cardiomyocytes and endothelial cells

open access: yesBeilstein Journal of Organic Chemistry, 2018
Background: Cardiomyopathy induced by the chemotherapeutic agents doxorubicin and daunorubicin is a major limiting factor for their application in cancer therapy.
