Responsiveness of cAMP production to adenosine receptor agonists in T84 cells. (a) Intracellular cAMP levels in confluent epithelial T84 cells incubated with various concentrations of either adenosine (Ado) or the selective A2B receptor antagonist PSB-1115 for 15 min. (b) Intracellular cAMP levels in confluent T84 cells incubated with various concentrations of the selective receptor agonists CPA (A1R), CGS21680 (A2AR), BAY60-6583 (A2BR), or IB-MECA (A3R). (c) Intracellular cAMP levels in confluent T84 cells incubated with various concentrations of selective receptor agonists (100 μM) and the A2B receptor antagonist PSB-1115 (100 nM). All data are expressed as mean ± SEM.
