Electrophysiological properties of rat nodose ganglion neurons co-transplanted with carotid bodies into the chick chorioallantoic membrane

open access: yesBiological Research, 2005
The electrophysiological properties of nodose ganglion neurons were evaluated immediately after removing nodose ganglia from young adult rats and 3 to 10 days after nodose ganglia implantation _either alone or co-implanted with carotid bodies_ onto the ...

Hydroxycobalamin Reveals the Involvement of Hydrogen Sulfide in the Hypoxic Responses of Rat Carotid Body Chemoreceptor Cells

open access: yesAntioxidants, 2019
Carotid body (CB) chemoreceptor cells sense arterial blood PO2, generating a neurosecretory response proportional to the intensity of hypoxia. Hydrogen sulfide (H2S) is a physiological gaseous messenger that is proposed to act as an oxygen sensor in CBs,

Carotid artery disease screening : assessment of criteria [PDF]

open access: yes, 1996
The Department of Radiology at St. Luke’s Hospital has provided a screening service for stroke related disease since April 1991. This consisted of Duplex Ultrasound screening (DUS) for Extracranial Carotid Artery Disease (ECAD) followed by angiography or

Meta-analysis of genome-wide association studies from the CHARGE consortium identifies common variants associated with carotid intima media thickness and plaque [PDF]

open access: yes, 2011
Carotid intima media thickness (cIMT) and plaque determined by ultrasonography are established measures of subclinical atherosclerosis that each predicts future cardiovascular disease events.

Increased calcium current in carotid body glomus cells following in vivo acclimatization to chronic hypoxia

open access: yes, 1996
1. Rat pups were gestated and born in normoxia (inspired O2 pressure 149 mmHg) or chronic hypoxia (insured O2 pressure 80 mmHg) to test whether chronic hypoxia alters carotid body glomus cell calcium currents.

Acid-Sensing Ion Channels’ Immunoreactivity in Nerve Profiles and Glomus Cells of the Human Carotid Body

open access: yes, 2023
The carotid body is a major peripheral chemoreceptor that senses changes in arterial blood oxygen, carbon dioxide, and pH, which is important for the regulation of breathing and cardiovascular function.

Hypoxia inducible factor-dependent upregulation of Agrp in glomus type I cells of the carotid body

open access: yesMolecular Metabolism
Agouti-related peptide (AgRP) is a well-established potent orexigenic peptide primarily expressed in hypothalamic neurons. Nevertheless, the expression and functional significance of extrahypothalamic AgRP remain poorly understood.

Carotid Body Function in Tyrosine Hydroxylase Conditional Olfr78 Knockout Mice

open access: yesFunction
The Olfr78 gene encodes a G-protein-coupled olfactory receptor that is expressed in several ectopic sites. Olfr78 is one of the most abundant mRNA species in carotid body (CB) glomus cells.

Activation of the Carotid Body by Kappa Opioid Receptors Mitigates Fentanyl-Induced Respiratory Depression

open access: yesFunction
Previous studies reported that opioids depress breathing by inhibiting respiratory neural networks in the brainstem. The effects of opioids on sensory inputs regulating breathing are less studied.
