MaxiK potassium channels in the function of chemoreceptor cells of the rat carotid body
American Journal of Physiology-Cell Physiology, 2009 Hypoxia activates chemoreceptor cells of the carotid body (CB) promoting an increase in their normoxic release of neurotransmitters. Catecholamine (CA) release rate parallels the intensity of hypoxia. Coupling of hypoxia to CA release requires cell depolarization, produced by inhibition of O2-regulated K+channels, and Ca2+entering the cells via voltage-

Type II Cells in the Human Carotid Body Display P2X7 Receptor and Pannexin-1 Immunoreactivity [PDF]
BiomoleculesThe carotid body is a peripheral chemoreceptor that consists of clusters of chemoreceptive type I cells, glia-like type II cells, afferent and efferent nerves, and sinusoidal capillaries and arterioles.

Vascular control of the CO2/H+-dependent drive to breathe
eLife, 2020 Respiratory chemoreceptors regulate breathing in response to changes in tissue CO2/H+. Blood flow is a fundamental determinant of tissue CO2/H+, yet little is known regarding how regulation of vascular tone in chemoreceptor regions contributes to ...

Mitochondrial Redox Signaling in O 2 -Sensing Chemoreceptor Cells
Antioxidants & Redox Signaling, 2022 Significance: Acute responses to hypoxia are essential for the survival of mammals. The carotid body (CB), the main arterial chemoreceptor, contains glomus cells with oxygen (O 2 )-sensitive K ...

SOS System Induction Inhibits the Assembly of Chemoreceptor Signaling Clusters in Salmonella enterica. [PDF]
PLoS ONE, 2016 Swarming, a flagellar-driven multicellular form of motility, is associated with bacterial virulence and increased antibiotic resistance. In this work we demonstrate that activation of the SOS response reversibly inhibits swarming motility by preventing ...

Solitary chemoreceptor cell proliferation in adult nasal epithelium [PDF]
Journal 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.
