Results l-VNIO, 1400W and NPA In accordance with previous reports (East and Garthwaite, 1991; Hopper and Garthwaite, 2006), NMDA (100 M) evoked a significant accumulation of cGMP in adult mouse hippocampal slices incubated with the PDE-2 inhibitor BAY 60C7550 (1 M). The response was blocked by the non-selective NOS inhibitor l-NNA (100 M), or the inhibitor of NO-targeted guanylyl cyclase ODQ (10 M). The basal/unstimulated and NMDA-evoked cGMP Amisulpride hydrochloride levels were not significantly different between slices from eNOS?/? and matched wild-type mice (Figure 1). Considering this result, together with findings that hippocampal slices prepared from healthy animals lack iNOS (Hopper and Garthwaite, 2006), and that >90% of hippocampal, Ca2+-induced NOS activity is abolished in mice lacking the major nNOS splice variant (Huang < 0.001). This increase was prevented by the non-selective NOS antagonist, l-NNA (100 M), or the NO-targeted guanylyl cyclase inhibitor, ODQ (10 M; anova with TukeyCKramer test, > 0.05 compared with basal). Basal and NMDA-induced cGMP levels did not differ significantly between slices from eNOS-deficient (eNOS?/?) and matched wild-type (eNOS+/+) mice (unpaired > 0.05).
