This study examined the ability of the anti-opioid
Neuropeptide FF
(
NPFF
) to modify the endogenous activity of nitric oxide (NO). Antinociceptive and hypothermic effects of 1DMe (D.Tyr-Leu-(n.Me)Phe-Gln-Pro-Gln-Arg-Phe-NH(2)), an
NPFF
agonist, and of L-
NAME
(N(omega)nitro-L-arginine methyl ester), an inhibitor of nitric oxide synthase, were investigated in mice. Intraperitoneal (i.p.) injection of L-
NAME
induced, in the hot plate test, a dose-dependent antinociception not reversed by naloxone, an opioid antagonist, but inhibited by L-Arg, the NO synthesis precursor. Intracerebroventricular (i.c.v.) injections of 1DMe inhibit the antinociceptive activity of L-
NAME
in a dose-dependent manner. On the contrary, L-
NAME
markedly potentiated hypothermia induced by 1DMe injected in the third ventricle. These data show that
Neuropeptide FF
receptors exert a dual effect on endogenous NO functions and could modulate pain transmission independently of opioids.
