Oxygen sensitivity of mitochondrial function in rat arterial chemoreceptor cells. [PDF]

open access: hybridJ Physiol, 2013
Key points Arterial chemoreceptors measure blood oxygen and are involved in the control of both breathing and the cardiovascular system. Oxygen is mostly used by cells in their mitochondria to generate energy. In this study we have investigated the effects of oxygen starvation (hypoxia) on the mitochondria of specialised oxygen sensing cells from ...

Reactive Oxidative Species in Carotid Body Chemoreception: Their Role in Oxygen Sensing and Cardiorespiratory Alterations Induced by Chronic Intermittent Hypoxia [PDF]

open access: yesAntioxidants
The carotid body (CB) senses arterial PO2, PCO2, and pH levels, eliciting reflex responses to maintain cardiorespiratory homeostasis. Chronic intermittent hypoxia (CIH), the hallmark of obstructive sleep apnea, elicits autonomic and cardiorespiratory ...

Single-array measurements reveal non-uniform, mosaic-like chemosensory arrays in bacteria [PDF]

open access: yesNature Communications
Motile bacteria use supramolecular arrays to detect effector gradients in their environment. In Escherichia coli, thousands of chemoreceptor molecules with diverse sensory properties cooperatively modulate the kinase activity of these arrays and, via ...

Solitary chemoreceptor cell proliferation in adult nasal epithelium [PDF]

open access: greenJournal of Neurocytology, 2005
Nasal trigeminal chemosensitivity in mice and rats is mediated in part by solitary chemoreceptor cells (SCCs) in the nasal epithelium (Finger et al., 2003). Many nasal SCCs express the G-protein alpha-gustducin as well as other elements of the bitter-taste signaling cascade including phospholipase Cbeta2, TRPM5 and T2R bitter-taste receptors.

Protein connectivity in chemotaxis receptor complexes [PDF]

open access: yes, 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 ...

Gene expression analyses reveal metabolic specifications in acute O2‐sensing chemoreceptor cells [PDF]

open access: bronzeThe Journal of Physiology, 2017
Key points Glomus cells in the carotid body (CB) and chromaffin cells in the adrenal medulla (AM) are essential for reflex cardiorespiratory adaptation to hypoxia. However, the mechanisms whereby these cells detect changes in O2 tension are poorly understood.

Carotid Body Tumor Resection – A Case Report

open access: yesJournal of Medical Sciences and Health, 2021
Carotid body tumours (CBT) are considered rare. Surgical excision is the treatment of choice and poses many anaesthetic challenges especially in large tumours.
