The effect of WIN55,212 was significantly reduced by pre-treatment with selective CB1- and CB2-receptor antagonists. The antagonists, when given alone, did not affect the KCl-evoked response. Conversely, WIN55,212 was unable to affect basal and CK- or carbachol-stimulated amylase release from pancreatic acini of guinea pig and rat.\n\nImmunofluorescent staining of rat pancreatic tissues showed that CB1- and CB2-receptors are expressed in lobules and in acinar cells and their presence in acinar cells was also shown by Western-blot analysis. After CK-induced pancreatitis, the expression of CB1-receptors in acinar cells was not changed, whilst a down-regulation of CB2-receptors was observed.\n\nIn conclusion, the present study shows that WIN55,212 inhibits amylase release from guinea pig and rat pancreatic lobules and, for the first time, that cannabinoid receptors are expressed in lobules of the rat pancreas, suggesting an inhibitory presynaptic role of this receptor system. Finally, in rat pancreatic acinar cells, CB1- and CB2-receptors, expressed both in basal conditions and after CK-induced pancreatitis but inactive on amylase secretion, have an unknown role both in physiological and pathological conditions." ; prodottidellaricerca:prodottoDi istituto:CDS059 , modulo:ID2573 , modulo:ID2651 ; pubblicazioni:autoreCNR unitaDiPersonaleInterno:MATRICOLA15719 , unitaDiPersonaleInterno:MATRICOLA45002 , unitaDiPersonaleInterno:MATRICOLA3516 , unitaDiPersonaleEsterno:ID4277 . @prefix parolechiave: . prodotto:ID4805 parolechiave:insiemeDiParoleChiave . ns12:ID510772 pubblicazioni:rivistaDi prodotto:ID4805 . parolechiave:insiemeDiParoleChiaveDi prodotto:ID4805 .
