1 Regulation of inducible nitric oxide synthase by cAMP-elevating phospho-diesterase inhibitors. Cyclic AMP nitric oxide synthase 2 Homo sapiens
2 Among the numerous genes controlled by cyclic adenosine monophosphate (cAMP)/protein kinase A signalling machinery is the gene encoding the inducible nitric oxide synthase (iNOS), an enzyme catalyzing the synthesis of a highly reactive free radical nitric oxide (NO). Cyclic AMP nitric oxide synthase 2 Homo sapiens
3 Among the numerous genes controlled by cyclic adenosine monophosphate (cAMP)/protein kinase A signalling machinery is the gene encoding the inducible nitric oxide synthase (iNOS), an enzyme catalyzing the synthesis of a highly reactive free radical nitric oxide (NO).

5 Among the numerous genes controlled by cyclic adenosine monophosphate (cAMP)/protein kinase A signalling machinery is the gene encoding the inducible nitric oxide synthase (iNOS), an enzyme catalyzing the synthesis of a highly reactive free radical nitric oxide (NO). Cyclic AMP nitric oxide synthase 2 Homo sapiens
6 A feasible way for cAMP-dependent therapeutic control of inflammation, including iNOS-mediated NO synthesis, could involve the administration of drugs that block the enzymatic activity of cAMP-degrading phosphodiesterases (PDE). Cyclic AMP nitric oxide synthase 2 Homo sapiens
7 A feasible way for cAMP-dependent therapeutic control of inflammation, including iNOS-mediated NO synthesis, could involve the administration of drugs that block the enzymatic activity of cAMP-degrading phosphodiesterases (PDE). Cyclic AMP nitric oxide synthase 2 Homo sapiens
8 Indeed, cAMP-elevating PDE inhibitors can influence iNOS activation in different cell types in vitro, and their potent anti-inflammatory effects in experimental disease models and clinical studies were frequently accompanied with profound modulation of NO production. Cyclic AMP nitric oxide synthase 2 Homo sapiens
9 A set of conflicting data has been generated over the years, ranging from strong suppression to marked enhancement of NO release by cAMP-increasing PDE inhibitors, depending on cell-type, iNOS stimuli, and/or the agents used. Cyclic AMP nitric oxide synthase 2 Homo sapiens
10 The present review summarizes the data on iNOS modulation by cAMP-elevating PDE inhibitors and possible mechanisms behind it, speculating on its contribution to the therapeutic effects of these drugs. Cyclic AMP nitric oxide synthase 2 Homo sapiens
