we have examined the effects of r-phenylisopropyladenosine ( r-pia ) and other adenosine analogues on basal , prostaglandin e1 ( pge1 ) - and forskolin-stimulated cyclic amp ( camp ) formation in intact n1e-115 neuroblastoma cells , to determine whether the cells contain a1 adenosine receptors that are negatively coupled with adenylate cyclase .
