The endocannabinoids anandamide and 2-arachidonyl glycerol (2-AG) bind to G protein-coupled central and peripheral cannabinoid receptors CB1 and CB2, respectively. Due to the relatively high expression of the CB2 isotype on peripheral immune cells, it has been hypothesized that this receptor mediates the immunosuppressive effects of cannabinoids.(More)
The sst2A receptor is expressed in the endocrine, gastrointestinal, and neuronal systems as well as in many hormone-sensitive tumors. This receptor is rapidly internalized and phosphorylated in growth hormone-R2 pituitary cells following somatostatin binding (Hipkin, R. W., Friedman, J., Clark, R. B., Eppler, C. M., and Schonbrunn, A. (1997) J. Biol. Chem.(More)
The expression of the cannabinoid peripheral cannabinoid receptor (CB(2)) receptor on peripheral immune cells suggests that compounds specific for CB(2) might be effective anti-inflammatory agents. In this report, we present the initial biological profiling of a novel triaryl bis-sulfone, Sch.336(More)
This study examined the functional significance of the type 1 (T1) and type 2 (T2) cAMP-dependent protein kinase (PK-A) isoenzymes in androgen production by mouse Leydig cells. Leydig cells were exposed to cAMP analogues selective for either of the two cAMP binding sites on the regulatory subunits of each PK-A isoenzyme. As the two binding sites have been(More)
Mouse Leydig cell androgen production can be acutely stimulated by atrial natriuretic factor (ANF) via cyclic guanosine 3',5'-monophosphate (cGMP). This stimulation can approach that seen with high concentrations of luteinizing hormone (LH) acting via cyclic adenosine 3',5'-monophosphate (cAMP). To assess the potential for synergistic interaction between(More)
