HIF-2a is essential for carotid body development and function
(eLife Sciences Publications, 2018-04-19)
Mammalian adaptation to oxygen flux occurs at many levels, from shifts in cellular metabolism to physiological adaptations facilitated by the sympathetic nervous system and carotid body (CB). Interactions between differing ...

Selective accumulation of biotin in arterial chemoreceptors: requirement for carotid body exocytotic dopamine secretion
(2016-12)
Biotin is a water-soluble vitamin required for the function of carboxylases as well asfor the regulation of gene expression. Here, we report that biotin accumulates in unusually largeamounts in cells of arterial chemoreceptors, ...

The carotid body, a neurogenic niche in the adult peripheral nervous system
(Univ pisa, 2010)
We have described a new population of adult neural stem cells residing in the carotid body, a chemoreceptor organ in the peripheral nervous system. These progenitor cells support neurogenesis in vivo in response to ...

Carotid body oxygen sensing and adaptation to hipoxia
(Springer, 2015-09)
The carotid body (CB) is the principal arterial chemoreceptor that mediates the hyperventilatory response to hypoxia. Our understanding of CB function and its role in disease mechanisms has progressed considerably in the ...

Gene expression analyses reveal metabolic specifications in acute O-2-sensing chemoreceptor cells
(Wiley, 2017-09)
Acute O2sensing is a fundamental property of cells in the peripheral chemoreceptors,e.g. glomus cells in the carotid body (CB) and chromaffin cells in the adrenal medulla (AM),and is necessary for adaptation to hypoxia. ...

Glucose sensing by carotid body glomus cells: potential implications in disease
(Frontiers Media, 2014-10-15)
The carotid body (CB) is a key chemoreceptor organ in which glomus cells sense changes in blood O2, CO2, and pH levels. CB glomus cells have also been found to detect hypoglycemia in both non-primate mammals and humans. ...

Redox signaling in acute oxygen sensing
(Elsevier, 2017-04-26)
Acute oxygen (O2) sensing is essential for individuals to survive under hypoxic conditions. The carotid body (CB) is the main peripheral chemoreceptor, which contains excitable and O2-sensitive glomus cells with O2-regulated ...

Carotid body chemosensory responses in mice deficient of TASK channels
(2010)
Background K+ channels of the TASK family are believed to participate in sensory transduction by chemoreceptor (glomus) cells of the carotid body (CB). However, studies on the systemic CB-mediated ventilatory response to ...
