Protection and repair of the nigrostriatal pathway with stem-cell-derived carotid body glomus cell transplants in chronic MPTP Parkinsonian model
(MDPI, 2023-03-14)
Antiparkinsonian carotid body (CB) cell therapy has been proven to be effective in rodent and nonhuman primate models of Parkinson’s disease (PD), exerting trophic protection and restoration of the dopaminergic nigrostriatal ...

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, ...

Rotenone selectively occludes sensitivity to hypoxia in rat carotid body glomus cells
(Wiley-Blackwell Publishing Ltd., 2003)
Carotid body glomus cells release transmitters in response to hypoxia due to the increase of excitability resulting from inhibition of O2 -regulated K+ channels. However, the mechanisms involved in the detection of changes ...

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 ...

Regulation of oxygen sensing by ion channels
(2004)
O2 sensing is of critical importance for cell survival and adaptation of living organisms to changing environments or physiological conditions. O2-sensitive ion channels are major effectors of the cellular responses to ...

Using redox-sensitive fluorescent probes to record real-time reactive oxygen species production in cells from mouse carotid body slices
(Cell Press, 2021)
Reactive oxygen species (ROS) are important signaling molecules for physiologic processes such as acute response to hypoxia. However, reliable real-time ROS measurement in cells has been a long-standing methodological ...

Oxygen regulation of breathing is abolished in mitochondrial complex III-deficient arterial chemoreceptors
(National Academy of Sciences, 2022)
Acute oxygen (O2) sensing is essential for adaptation of organisms to hypoxic environments or medical conditions with restricted exchange of gases in the lung. The main acute O2-sensing organ is the carotid body (CB), which ...

Unexpected obesity, rather than tumorigenesis, in a conditional mouse model of mitochondrial complex II deficiency
(Federation amer soc exp biol, 2021)
Mutations in any of the genes encoding the four subunits of succinate dehydrogenase (SDH), a mitochondrial membrane-bound enzyme complex that is involved in both the tricarboxylic acid cycle and the electron transport ...

Lactate sensing mechanisms in arterial chemoreceptor cells
(2021)
Classically considered a by-product of anaerobic metabolism, lactate is now viewed as a fundamental fuel for oxidative phosphorylation in mitochondria, and preferred over glucose by many tissues. Lactate is also a signaling ...
