Inosine is an endogenous nucleoside that has anti-inflammatory and antinociceptive properties. Inosine is a metabolite of adenosine, and some of its actions suggest the involvement of adenosine A1 receptors (A1Rs). The purpose of this study was to better understand mechanisms of inosine-induced antinociception by investigating the role of A1Rs and purine(More)
Inosine is the first metabolite of adenosine. It exerts an antinociceptive effect by activating the adenosine A1 and A2A receptors. We have previously demonstrated that inosine exhibits antinociceptive properties in acute and chronic mice models of nociception. The aim of this study was to investigate the involvement of pertussis toxin-sensitive(More)
BACKGROUND It has been shown that chronic pain is able to induce depressive disorders in humans, in part, due to peripheral inflammation that reaches the central nervous system. However, the mechanisms involved remain to be established. The purpose of this study was to investigate whether sciatic nerve crush could produce depression-like behaviors, in(More)
