Effects of mitochondrial poisons on glutathione redox potential and carotid body chemoreceptor activity [PDF]

, 2009
Producción CientíficaLowoxygen sensing in chemoreceptor cells involves the inhibition of specific plasma membrane K+ channels, suggesting that mitochondria-derived reactive oxygen species (ROS) link hypoxia to K+ channel inhibition, subsequent cell ...

Effects of low glucose on carotid body chemoreceptor cell activity studied in cultures of intact organs and in dissociated cells

, 2015
The participation of the carotid body (CB) in glucose homeostasis and evidence obtained in simplified cultured CB slices or dissociated cells have led to the proposal that CB chemoreceptor cells are glucoreceptors.

Solitary chemoreceptor cells in the nasal cavity serve as sentinels of respiration [PDF]

Proceedings of the National Academy of Sciences, 2003
Inhalation of irritating substances leads to activation of the trigeminal nerve, triggering protective reflexes that include apnea or sneezing. Receptors for trigeminal irritants are generally assumed to be located exclusively on free nerve endings within the nasal epithelium, requiring that trigeminal irritants diffuse through the junctional ...

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 ...

Role of Glutathione Redox State in Oxygen Sensing by Carotid Body Chemoreceptor Cells [PDF]

, 2004
Producción CientíficaThis article first presents some basic structural traits of the carotid body (CB) arterial chemoreceptors to understand the relationship between the arterial blood PO2 and the activation of chemoreceptor cells, which are the O2 ...

Developmental changes in intracellular Ca2+ response of carotid chemoreceptor cells to hypoxia

, 1995
The carotid chemoreceptor response to hypoxia is weak just after birth and increases during postnatal development. The mechanisms underlying chemoreceptor maturation are unknown.

A critical reappraisal of the carotid sinus and carotid bulb: Distinguishing neurohistological function from vascular geometry

The Anatomical Record, EarlyView.
This review redefines the carotid bulb (CB) as a variable geometric dilation shaped by hemodynamics and the carotid sinus (CS) as a conserved neurohistological baroreceptor field. Distinguishing these entities clarifies a century of anatomical confusion and links geometry, neurohistology, and clinical interpretation within a unified framework ...

Characterization of cultured chemoreceptor cells dissociated from adult rabbit carotid body

, 1992
Short-term cell cultures were obtained from enzymatically dissociated carotid bodies from adult rabbits, and morphological and functional characterization of the cultured chemoreceptor cells were carried out. Under phase contrast, freshly isolated type I
