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 ...

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 ...

The carotid body: a physiologically relevant germinal niche in the adult peripheral nervous system
(Springer, 2018-11-29)
Oxygen constitutes a vital element for the survival of every single cell in multicellular aerobic organisms like mammals. A complex homeostatic oxygen-sensing system has evolved in these organisms, including detectors and ...

Neurotransmitter Modulation of Carotid Body Germinal Niche
(MDPI AG, 2020-11-03)
The carotid body (CB), a neural-crest-derived organ and the main arterial chemoreceptor in mammals, is composed of clusters of cells called glomeruli. Each glomerulus contains neuron-like, O2-sensing glomus cells, which ...

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. ...

Gene expression profiling supports the neural crest origin of adult rodent carotid body stem cells and identifies CD10 as a marker for mesectoderm-committed progenitors
(WILEY, 2016)
Neural stem cells (NSCs) are promising tools for understanding nervous system plasticity and repair, but their use is hampered by the lack of markers suitable for their prospective isolation and characterization. The carotid ...

Long-term immunosuppression for CNS mouse xenotransplantation: Effects on nigrostriatal neurodegeneration and neuroprotective carotid body cell therapy
(Wiley, 2018)
Abstract Background: The use of long-term immunosuppressive treatments on neural trans plantation has been controversial during the last decades. Although nowadays there is a consensus about the necessity of maintaining ...

Molecular mechanisms of acute oxygen sensing by arterial chemoreceptor cells. Role of Hif2α
(Frontiers Research Foundation, 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. Glomus ...

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. ...
