The present study investigated, in rats, whether blockade of cannabinoid CB1 receptors may alter Fos protein expression in a manner comparable to that observed with antipsychotic drugs. Intraperitoneal administration of the selective CB1 receptor antagonist, SR141716, dose-dependently (1.0, 3.0 and 10 mg/kg) increased Fos-like immunoreactivity in(More)
OBJECTIVES In the adult human brain, neurogenesis occurs in the SVZ and the dentate gyrus of the hippocampus, but it is still unclear whether persistent neural progenitor/stem cells are also present in other brain areas. The present work studies the possibility of obtaining neural progenitor/stem cells from the temporal lobe and investigates their potential(More)
The neurotrophic factor promoting activity of the neuroprotective compound SR57746A was evaluated in primary cultures of neonatal rat cortical astrocytes by studying the synthesis of nerve growth factor (NGF) and brain-derived neurotrophic factor (BDNF). A concentration- and time-dependent increase of nerve growth factor mRNA was induced by SR57746A (10(More)
The effects of SR 31742A, a specific sigma ligand, were investigated on neurotensin (NT) biosynthesis in the basal ganglia of the rat. Both single and repeated treatments with either SR 31742A (20 mg/kg i.p.) or haloperidol (1 mg/kg i.p.) increased the concentration of NT-like immunoreactivity (NT-li) in the nucleus accumbens. In contrast to haloperidol,(More)
The effects of SR 31742A, a specific sigma site ligand, were investigated on regional neurotensin concentrations in rat brain. Both acute and chronic (21-day) treatment with either SR 31742A (20 mg/kg i.p.) or haloperidol (1 mg/kg i.p.) increased the neurotensin-like immunoreactivity in the nucleus accumbens. In contrast to haloperidol, the administration(More)
