The extracellular "cAMP-adenosine pathway" refers to the local production of adenosine mediated by cAMP egress into the extracellular space, conversion of cAMP to AMP by ectophosphodiesterase, and the metabolism of AMP to adenosine by ecto-5'-nucleotidase. The goal of this study
Chronic treatment of rats with 90 microg/kg/day DPSPX (1,3-dipropyl-8-sulphophenylxanthine) during seven days leads to a hypertensive state which is characterized by marked morphological changes of the blood vessel walls as well as by important functional alterations. While the angiotensin-converting enzyme

Recent studies have demonstrated that three membrane-permeant A(1) receptor antagonists reduced infarct size in a model of ischemia followed by brief reperfusion. However, it was not determined whether cardioprotection was mediated by nonspecific intracellular effects of these highly lipophilic drugs
Carbon monoxide has been identified as an endogenous biological messenger in the brain. Heme oxygenase catalyzes the metabolism of heme to carbon monoxide and biliverdin. Previously, we have shown the involvement of carbon monoxide in central cardiovascular regulation, baroreflex modulation

Treatment of Wistar rats for 7 days with 1,3-dipropyl-8-sulfophenylxanthine (DPSPX), an antagonist of adenosine receptors, induces long-lasting hypertension associated with marked changes in vascular structure and reactivity and renin-angiotensin system activation. This study aimed at evaluating the role of oxidative
