Acute oxygen sensing: diverse but convergent mechanisms in airway and arterial chemoreceptors [PDF]
Respiratory Research, 2001 Airway neuroepithelial bodies sense changes in inspired O2, whereas arterial O2 levels are monitored primarily by the carotid body. Both respond to hypoxia by initiating corrective cardiorespiratory reflexes, thereby optimising gas exchange in the face ...

Protein connectivity in chemotaxis receptor complexes [PDF]
, 2015 The chemotaxis sensory system allows bacteria such as Escherichia coli to swim towards nutrients and away from repellents. The underlying pathway is remarkably sensitive in detecting chemical gradients over a wide range of ambient concentrations ...

Ibuprofen Blunts Ventilatory Acclimatization to Sustained Hypoxia in Humans. [PDF]
, 2016 Ventilatory acclimatization to hypoxia is a time-dependent increase in ventilation and the hypoxic ventilatory response (HVR) that involves neural plasticity in both carotid body chemoreceptors and brainstem respiratory centers.

Structure and dynamics of the E. coli chemotaxis core signaling complex by cryo-electron tomography and molecular simulations [PDF]
, 2020 To enable the processing of chemical gradients, chemotactic bacteria possess large arrays of transmembrane chemoreceptors, the histidine kinase CheA, and the adaptor protein CheW, organized as coupled core-signaling units (CSU). Despite decades of study,

Carotid Body Tumour: A Rare Case Report [PDF]
International Journal of Anatomy Radiology and Surgery, 2017 Carotid Body Tumour (CBT) is a uncommon tumour which arises from a chemoreceptor tissue, which is present at the bifurcation of common carotid arteries. Not many case reports have been reported for carotid body tumours. We report an unusual case of a

Opposing chemosensory functions of closely related gustatory receptors
eLife, 2023 In the fruit fly Drosophila melanogaster, gustatory sensory neurons express taste receptors that are tuned to distinct groups of chemicals, thereby activating neural ensembles that elicit either feeding or avoidance behavior.

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 ...

Prevalence and Specificity of Chemoreceptor Profiles in Plant-Associated Bacteria
mSystems, 2021 Chemosensory pathways are among the most abundant prokaryotic signal transduction systems, allowing bacteria to sense and respond to environmental stimuli. Signaling is typically initiated by the binding of specific molecules to the ligand binding domain
