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 ...

Identification and Functional Characterization of a K1 Channel a- Subunit with Regulatory Properties Specific to Brain
(1997)
The physiological diversity of K1 channels mainly depends on the expression of several genes encoding different a-subunits. We have cloned a new K1 channel a-subunit (Kv2.3r) that is unable to form functional channels on ...

Effect of hypoxia on lung gene expression and proteomic profile: insights into the pulmonary surfactant response
(Elsevier, 2014)
Exposure of lung to hypoxia has been previously reported to be associated with significant alterations in the protein content of bronchoalveolar lavage (BAL) and lung tissue. In the present work we have used a proteomic ...

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. ...

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, ...

Properties of Calcium and Potassium Currents of Clonal Adrenocortical Cells
(1989)
The ionic currents of clonal Y-1 adrenocortical cells were studied using the whole-cell variant of the patch-clamp technique. These cells had two major current components: a large outward current carried by K ions, and a ...

Hypoxia induces voltage-dependent Ca2+ entry and quantal dopamine secretion in carotid body glomus cells
(1994)
We have investigated the changes of cytosolic [Ca2+1 and the secretory -activity in single glomus cells dispersed from rabbit carotid bodies during exposure to solutions with variable 02 tension (Po2). In normoxic conditions ...

Oxygen sensing by ion channels and chemotransduction in single glomus cells
(1996)
We have monitored cytosolic [Ca2+] and dopamine release in intact fura-2-loaded glomus cells with microfluoroimetry and a polarized carbon fiber electrode. Exposure to low PO2 produced a rise of cytosolic [Ca2+] with two ...
