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 ...

Resistance of subventricular neural stem cells to chronic hypoxemia despite structural disorganization of the germinal center and impairment of neuronal and oligodendrocyte survival
(Dove Medical Press Ltd., 2015)
Chronic hypoxemia, as evidenced in de-acclimatized high-altitude residents or in patients with chronic obstructive respiratory disorders, is a common medical condition that can produce serious neurological alterations. ...

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 ...
Tesis Doctoral
Hipertrofia del cuerpo carotídeo en hipoxia crónica: mecanismos de activación, proliferación y diferenciación de los progenitores neurales en el sistema nervioso periférico
(2014-04-25)
The goal of this doctoral thesis is to achieve a better understanding of the biology and behavior of the recently discovered adult carotid body neural stem cells. The work focuses on two main objectives. First, to study ...

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 ...

Trophic restoration of the nigrostriatal dopaminergic pathway in long-term carotid body-grafted parkinsonian rats
(2003)
We studied the mechanisms underlying long-term functional recovery of hemiparkinsonian rats grafted intrastriatally with carotid body (CB) cell aggregates. Amelioration of their motor syndrome is a result of the trophic ...

An O-2-sensitive glomus cell-stem cell synapse induces carotid body growth in chronic hipoxia
(CELL PRESS, 2014-01-16)
Neural stem cells (NSCs) exist in germinal centers of the adult brain and in the carotid body (CB), an oxygen-sensing organ that grows under chronic hypoxemia. How stem cell lineage differentiation into mature glomus cells ...

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 ...
