Defining Two Chemosensory Arrays in Shewanella oneidensis
Biomolecules, 2022 Shewanella oneidensis has 2 functional chemosensory systems named Che1 and Che3, and 27 chemoreceptors. Che3 is dedicated to chemotaxis while Che1 could be involved in RpoS post-translational regulation.

KISS1 and KISS1R expression in the human and rat carotid body and superior cervical ganglion
European Journal of Histochemistry, 2011 KISS1 and its receptor, KISS1R, have both been found to be expressed in central nervous system, but few data are present in the literature about their distribution in peripheral nervous structures.

The Interaction of RecA With Both CheA and CheW Is Required for Chemotaxis
Frontiers in Microbiology, 2020 Salmonella enterica is the most frequently reported cause of foodborne illness. As in other microorganisms, chemotaxis affords key physiological benefits, including enhanced access to growth substrates, but also plays an important role in infection and ...

Viral gene transfer of dominant-negative Kv4 construct suppresses an O2-sensitive K+ current in chemoreceptor cells [PDF]
, 2000 Producción CientíficaHypoxia initiates the neurosecretory response of the carotid body (CB) by inhibiting one or more potassium channels in the chemoreceptor cells.

Biomolecules, 2020 Chemotaxis is an important virulence factor of the foodborne pathogen Campylobacter jejuni. Inactivation of chemoreceptor Tlp3 reduces the ability of C. jejuni to invade human and chicken cells and to colonise the jejunal mucosa of mice. Knowledge of the

Engineered single‐ and multi‐cell chemotaxis pathways in E. coli
Molecular Systems Biology, 2009 We have engineered the chemotaxis system of Escherichia coli to respond to molecules that are not attractants for wild‐type cells. The system depends on an artificially introduced enzymatic activity that converts the target molecule into a ligand for an ...

Solitary chemoreceptor cell survival is independent of intact trigeminal innervation [PDF]
Journal of Comparative Neurology, 2008 AbstractNasal solitary chemoreceptor cells (SCCs) are a population of specialized chemosensory epithelial cells presumed to broaden trigeminal chemoreceptivity in mammals (Finger et al. [2003] Proc Natl Acad Sci USA 100:8981–8986). SCCs are innervated by peptidergic trigeminal nerve fibers (Finger et al.

Marine Drugs, 2011 Carotid bodies (CBs) are secondary sensory receptors in which the sensing elements, chemoreceptor cells, are activated by decreases in arterial PO2 (hypoxic hypoxia).

Guinea Pig Oxygen-Sensing and Carotid Body Functional Properties
Frontiers in Physiology, 2017 Mammals have developed different mechanisms to maintain oxygen supply to cells in response to hypoxia. One of those mechanisms, the carotid body (CB) chemoreceptors, is able to detect physiological hypoxia and generate homeostatic reflex responses ...

Anaesthetic Management of Chemodectoma Excision [PDF]
The Indian Anaesthetists' Forum, 2007 Carotid body tumours (CBTs) or chemodectoma are rare non- chromaffin paragangliomas arising from the chemoreceptor cells found at the carotid bifurcation.
