Amino acid modulation of the carotid body selectively modulates peripheral chemoreceptor respiratory reflex. [PDF]

open access: yesJ Physiol
Abstract figure legend When the carotid body (CB) detects low oxygen levels (hypoxia), this leads to: (1) depolarization of the chemosensory cells (glomus cells) within the CB – the resulting increase in intracellular Ca2+ stimulates the exocytotic co‐release of vesicles containing ATP and glutamate; (2) synaptic ATP acts on postsynaptic petrosal ...

Exacerbated ATP transmission in the carotid body is linked to glomus cell expansion in spontaneously hypertensive rats. [PDF]

open access: yesJ Physiol
Abstract figure legend Exacerbated ATP signalling in the carotid body (CB) of spontaneously hypertensive rats (SHRs) arises from expansion of the chemosensory glomus cell compartment and reduced extracellular ATP metabolism, leading to increased purinergic drive.

Carotid artery stenting compared with endarterectomy in patients with symptomatic carotid stenosis (International Carotid Stenting Study): an interim analysis of a randomised controlled trial [PDF]

open access: yes, 2010
Background Stents are an alternative treatment to carotid endarterectomy for symptomatic carotid stenosis, but previous trials have not established equivalent safety and efficacy.

Targeting the Carotid Body Function With Big-K<sup>+</sup>-Channel Blocker ENA-001 in Opioid-Induced Respiratory Depression: A Scoping Review. [PDF]

open access: yesPharmacol Res Perspect
ABSTRACT Opioids, most intravenous anesthetics and various illicit substances can cause fatal respiratory depression by depressing central respiratory networks. ENA‐001, a ventilatory modulator targeting the carotid bodies, has emerged as a potential countermeasure without impairing analgesia or hypnosis.

Revealing natural relationships among arbuscular mycorrhizal fungi: culture line BEG47 represents Diversispora epigaea, not Glomus versiforme [PDF]

open access: yes, 2011
Background: Understanding the mechanisms underlying biological phenomena, such as evolutionarily conservative trait inheritance, is predicated on knowledge of the natural relationships among organisms.

Molecular Mechanisms of Acute Oxygen Sensing by Arterial Chemoreceptor Cells. Role of Hif2α

open access: yesFrontiers in Physiology, 2020
Carotid body glomus cells are multimodal arterial chemoreceptors able to sense and integrate changes in several physical and chemical parameters in the blood. These cells are also essential for O2 homeostasis.

Carotid endarterectomy in Russia. What if current guidelines do not answer difficult questions?

open access: yesРоссийский кардиологический журнал, 2023
This literature review covers the publications of Russian vascular surgeons in recent years and deals with debatable issues of carotid surgery, including: 1. What is the best technique for carotid endarterectomy (CEA)? 2.
