Hydroxycobalamin Reveals the Involvement of Hydrogen Sulfide in the Hypoxic Responses of Rat Carotid Body Chemoreceptor Cells.

Antioxidants (Basel, Switzerland)

Gallego-Martin T, Prieto-Lloret J, Aaronson PI, Rocher A, Obeso A.
PMID: 30871199
Antioxidants (Basel). 2019 Mar 13;8(3). doi: 10.3390/antiox8030062.

Carotid body (CB) chemoreceptor cells sense arterial blood PO₂, generating a neurosecretory response proportional to the intensity of hypoxia. Hydrogen sulfide (H₂S) is a physiological gaseous messenger that is proposed to act as an oxygen sensor in CBs, although...

Front Physiol. 2018 Jun 05;9:694. doi: 10.3389/fphys.2018.00694. eCollection 2018.

Clinical and experimental evidence indicates a positive correlation between chronic intermittent hypoxia (CIH), increased carotid body (CB) chemosensitivity, enhanced sympatho-respiratory coupling and arterial hypertension and cardiovascular disease. Several groups have reported that both the afferent and efferent arms of...

l-Phenylalanine Restores Vascular Function in Spontaneously Hypertensive Rats Through Activation of the GCH1-GFRP Complex.

JACC. Basic to translational science

Reduced nitric oxide (NO) bioavailability correlates with impaired cardiovascular function. NO is extremely labile and has been challenging to develop as a therapeutic agent. However, NO bioavailability could be enhanced by pharmacologically targeting endogenous NO regulatory pathways. Tetrahydrobiopterin, an...

Chronic Intermittent Hypoxia Induces Early-Stage Metabolic Dysfunction Independently of Adipose Tissue Deregulation.

Antioxidants (Basel, Switzerland)

Martins FO, Sacramento JF, Olea E, Melo BF, Prieto-Lloret J, Obeso A, Rocher A, Matafome P, Monteiro EC, Conde SV.

Several studies demonstrated a link between obstructive sleep apnea (OSA) and the development of insulin resistance. However, the main event triggering insulin resistance in OSA remains to be clarified. Herein, we investigated the effect of mild and severe chronic...
