Endogenous nitric oxide modulates behavioural effects elicited by substance P in rat

Abstract

Several studies have shown that the undecapeptide, substance P, alters behaviour following central or peripheral administration in the rat. Here we report that l-arginine administration increases substance P-induced locomotion and changes in food intake in rats. NG-Nitro-l-arginine methyl ester, a specific inhibitor of nitric oxide synthase, reduces substance P-induced effects. These results suggest that endogenous nitric oxide plays a role in the modulation of the catecholaminergic effect of substance P on motor behaviour. They also clarify the mechanism underlying food intake induced by substance P.

    Disruption of nNOS function also potentiates catalepsy induced via D2-like receptor antagonist administration (Cavas and Navarro, 2002; Del Bel and Guimaraes, 2000). Additionally, locomotion stimulated by substance P (Mancuso et al., 1994), NMDA receptor antagonists (Deutsch et al., 1996), and D1/5 and D2-like receptor agonists (Starr and Starr, 1995) is decreased following systemic administration of NOS inhibitors. The psychomimetic drug phencyclidine has also been reported to modulate locomotor activity in a manner that is sensitive to both NO donors and nNOS inhibitors, although these studies have produced contradictory results (Bujas-Bobanovic et al., 2000; Johansson et al., 1999, 1997; Klamer et al., 2005; Noda et al., 1995, 1996).

  • Brain kinin B1 receptor is upregulated by the oxidative stress and its activation leads to stereotypic nociceptive behavior in insulin-resistant rats

    While glutamate is recognized as a classical neurotransmitter involved in various cerebral functions, including NMDA-induced grooming behavior [42], SP is known to initiate stereotypic nocifensive behavior [8,15,29,39] and to contribute to the defence reaction in response to stress [8–10]. In the brain, endogenous NO plays a role in the effect of SP on motor behavior [36]. This is keeping with the presence of all components of the kallikrein–kinin system in normal brain and the upregulation of B1R in pathologic brain [4,11,33,37].

    A growing body of evidence derived from animal models reveals a compelling role of nitric oxide (NO), a unique gaseous neurotransmitter and neuromodulator with a broad spectrum of activities in the mammalian brain (Guix et al., 2005), in the regulation of motor function. Behavioral studies have demonstrated that acute administration of selective or non-selective neuronal nitric oxide synthase (nNOS) inhibitors to rodents, reduced spontaneous locomotor activity (Stewart et al., 1994; Dzoljic et al., 1997; Sandi et al., 1995) and hyperlocomotion induced by cocaine (Pudiak and Bozarth, 1993; Przegaliński and Filip, 1997), morphine (Calignano et al., 1993), substance P (Mancuso et al., 1994) and amphetamine or methamphetamine (Przegaliński and Filip, 1997; Ohno and Watanabe, 1995; Abekawa et al., 1994). Locomotor activity enhanced by selective dopamine D1 and D2 receptor agonists (Starr and Starr, 1995; Przegaliński and Filip, 1997) and the NMDA receptor antagonist MK-801 (Deutsch et al., 1996) was also decreased by these inhibitors.

    A growing body of evidence from animals studies indicates that NO is a key modulator of neuronal activity in the dorsal striatum and a critical factor for the regulation of motor function and synaptic plasticity [37, 158]. Behavioral studies carried out on rodents demonstrated that non-selective and selective nNOS inhibitors reduced spontaneous locomotor activity [43, 137, 143] and hyperlocomotion induced by cocaine [122, 123], morphine [19], substance P [100] as well as by amphetamine or metamphetamine [1, 113, 122]. Also locomotor activity stimulated by selective dopamine D1 and D2 receptor agonists [122, 141] and the N-methyl-D-aspartic acid (NMDA) receptor antagonist MK-801 [39] was decreased by these inhibitors.

    Disruption of NOS function also potentiates catalepsy induced via D2-like receptor antagonist administration (Del Bel and Guimaraes, 2000; Cavas and Navarro, 2002). Additionally, locomotion stimulated by substance P (Mancuso et al., 1994), NMDA receptor antagonists (Deutsch et al., 1996), and D1/5 and D2-like receptor agonists (Starr and Starr, 1995) is decreased following systemic administration of NOS inhibitors. Elevations in striatal levels of cAMP and cGMP observed in PDE1B knock-out mice are associated with greater locomotor hyperactivity induced via administration of DA agonists (Reed et al., 2002).
