Pharmacology of 5-hydroxytryptamine receptors in frog skin epithelium.

abstract：BACKGROUND AND PURPOSE:Recently, we demonstrated that the nucleus accumbens (NAC) is required for the acquisition and expression of relief memory. The purpose of this study was to investigate the role of NMDA receptors within the NAC in relief learning. EXPERIMENTAL APPROACH:The NMDA receptor antagonist 2-amino-5-phos...

abstract：BACKGROUND AND PURPOSE:The adenosine 2B (A2B) receptor is the predominant adenosine receptor expressed in the colon. Acting through the A2B receptor, adenosine mediates chloride secretion, as well as fibronectin and interleukin (IL)-6 synthesis and secretion in intestinal epithelial cells. A2B receptor mRNA and protein...
