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).

Universal architecture of bacterial chemoreceptor arrays [PDF]
, 2009 Chemoreceptors are key components of the high-performance signal transduction system that controls bacterial chemotaxis. Chemoreceptors are typically localized in a cluster at the cell pole, where interactions among the receptors in the cluster are ...

Ionic currents in dispersed chemoreceptor cells of the mammalian carotid body. [PDF]
The Journal of general physiology, 1989 Ionic currents of enzymatically dispersed type I and type II cells of the carotid body have been studied using the whole cell variant of the patch-clamp technique. Type II cells only have a tiny, slowly activating outward potassium current. By contrast, in every type I chemoreceptor cell studied we found (a) sodium, (b) calcium, and (c) potassium ...

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.

Chemotaxis cluster 1 proteins form cytoplasmic arrays in Vibrio cholera and are stabilized by a double signaling domain receptor DosM [PDF]
, 2016 Nearly all motile bacterial cells use a highly sensitive and adaptable sensory system to detect changes in nutrient concentrations in the environment and guide their movements toward attractants and away from repellents.

Insights into the control and consequences of breathing adjustments in fishes-from larvae to adults
Frontiers in Physiology, 2023 Adjustments of ventilation in fishes to regulate the volume of water flowing over the gills are critically important responses to match branchial gas transfer with metabolic needs and to defend homeostasis during environmental fluctuations in O2 and/or ...

Rotenone selectively occludes sensitivity to hypoxia in rat carotid body glomus cells [PDF]
, 2003 Carotid body glomus cells release transmitters in response to hypoxia due to the increase of excitability resulting from inhibition of O2 -regulated K+ channels. However, the mechanisms involved in the detection of changes of O2 tension are unknown.

Repurposing a chemosensory macromolecular machine [PDF]
, 2020 How complex, multi-component macromolecular machines evolved remains poorly understood. Here we reveal the evolutionary origins of the chemosensory machinery that controls flagellar motility in Escherichia coli.

Complex evolutionary dynamics of massively expanded chemosensory receptor families in an extreme generalist chelicerate herbivore [PDF]
, 2016 While mechanisms to detoxify plant produced, anti-herbivore compounds have been associated with plant host use by herbivores, less is known about the role of chemosensory perception in their life histories.
