Abstract
The prenatal stress (PNS) model in rodents can induce different abnormal responses that replicate the pathophysiology of depression. We applied this model to evaluate the efficacy of piromelatine (Pir), a novel melatonin analog developed for the treatment of insomnia, in male and female offspring. Adult PNS rats from both sexes showed comparable disturbance associated with high levels of anxiety and depressive responses. Both males and females with PNS demonstrated impaired feedback inhibition of the hypothalamic-pituitary-adrenal (HPA) axis compared to the intact offspring and increased glucocorticoid receptors in the hippocampus. However, opposite to female offspring, the male PNS rats showed an increased expression of mineralocorticoid receptors in the hippocampus. Piromelatine (20 mg/kg, i.p., for 21 days injected from postnatal day 60) attenuated the high anxiety level tested in the open field, elevated plus-maze and light-dark test, and depressive-like behavior in the sucrose preference and the forced swimming tests in a sex-specific manner. The drug reversed to control level stress-induced increase of plasma corticosterone 120 min later in both sexes. Piromelatine also corrected to control level the PNS-induced alterations of corticosteroid receptors only in male offspring. Our findings suggest that the piromelatine treatment exerts beneficial effects on impaired behavioral responses and dysregulated HPA axis in both sexes, while it corrects the PNS-induced changes in the hippocampal corticosteroid receptors only in male offspring.

The role of serotonin in drug use and addiction. Behav Brain Res 2014; 277:146-92.

Abstract
The use of psychoactive drugs is a wide spread behaviour in human societies. The systematic use of a drug requires the establishment of different drug use-associated behaviours which need to be learned and controlled. However, controlled drug use may develop into compulsive drug use and addiction, a major psychiatric disorder with severe consequences for the individual and society. Here we review the role of the serotonergic (5-HT) system in the establishment of drug use-associated behaviours on the one hand and the transition and maintenance of addiction on the other hand for the drugs: cocaine, amphetamine, methamphetamine, MDMA (ecstasy), morphine/heroin, cannabis, alcohol, and nicotine. Results show a crucial, but distinct involvement of the 5-HT system in both processes with considerable overlap between psychostimulant and opioidergic drugs and alcohol. A new functional model suggests specific adaptations in the 5-HT system, which coincide with the establishment of controlled drug use-associated behaviours. These serotonergic adaptations render the nervous system susceptible to the transition to compulsive drug use behaviours and often overlap with genetic risk factors for addiction. Altogether we suggest a new trajectory by which serotonergic neuroadaptations induced by first drug exposure pave the way for the establishment of addiction.

Abstract
Previous studies with acute tryptophan depletion, leading to transient central 5-HT reductions, showed no effects on affective behavior but impaired object memory. In the present study, the behavioral effects of a 5,7-dihydroxytryptamine (5,7-DHT) lesion in the dorsal raphe were evaluated in animal models of anxiety (open field test), depression (forced swimming test), behavioral inhibition (discrete fixed interval test) and cognition (object recognition task). The corticosterone response to a stress condition was examined at several intervals after 5,7-DHT treatment. The substantial reduction in neuronal 5-HT markers in the dorsal raphe did not affect anxiety-related, depressive-like or impulsive behavior. Compared to the SHAM group, the lesioned rats showed a lower response latency to obtain a reward, indicating a quick and accurate reaction to a stimulus. No differences were found in the progressive ratio test for food motivation. A marked impairment in object recognition was found. The 5,7-DHT treatment did not affect the corticosterone response to a stressful situation. Overall, these results corroborate studies with acute tryptophan depletion suggesting a role of 5-HT in object memory, but not affective behavior.

Brain serotonin depletion by lesions of the median raphe nucleus enhances the psychotomimetic action of phencyclidine, but not dizocilpine (MK-801), in rats. Brain Res 2005; 1049:217-26. [PMID: 15953591 DOI: 10.1016/j.brainres.2005.05.017] [Citation(s) in RCA: 16] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2005] [Revised: 05/09/2005] [Accepted: 05/10/2005] [Indexed: 10/25/2022]
Abstract
We have previously shown that brain serotonin depletion by lesions of the median raphe nucleus (MRN) causes enhancement of phencyclidine-induced locomotor hyperactivity [S. Kusljic, D.L. Copolov, M. van den Buuse, Differential role of serotonergic projections arising from the dorsal and median raphe nuclei in locomotor hyperactivity and prepulse inhibition, Neuropsychopharmacology 28 (2003) 2138-2147]. In this study, we extend our previous work by (1) comparing the effect of phencyclidine with that of another NMDA receptor antagonist, dizocilpine (MK-801); (2) investigate behavioral changes in more detail; (3) assess in detail the effect of raphe lesions on regional serotonin levels in the brain. Male Sprague-Dawley rats received microinjection of the serotonergic neurotoxin 5,7-dihydroxytryptamine into the MRN or dorsal raphe nucleus (DRN). The effects of treatment with saline, phencyclidine and MK-801 on locomotor activity were determined 2 weeks after the surgery. MRN lesions caused serotonin depletion in the dorsal hippocampus, whereas DRN lesions caused serotonin depletion in the frontal cortex, striatum and ventral hippocampus. There was a significant increase in phencyclidine-induced locomotor hyperactivity in the MRN-lesioned group compared to sham-operated controls. Further analysis of behavior showed that phencyclidine-induced hyperambulation, but not stereotypy or rearing, was significantly higher in MRN-lesioned rats compared to controls. In contrast, there was no significant effect of the lesions on the psychotomimetic effect of MK-801. These results indicate that a hyposerotonergic state induced by destruction of projections from the MRN leads to altered brain circuitry that is responsible for the regulation of phencyclidine-but not MK-801-induced locomotor hyperactivity. Thus, MRN projections may play an inhibitory role in mechanisms involved in symptoms of schizophrenia.

Abstract
Altered hippocampal function and brain serotonin activity are implicated in the development and symptoms of schizophrenia. We have previously shown that lesions of the median raphe nucleus, but not the dorsal raphe nucleus, produced a marked enhancement of locomotor hyperactivity induced by phencyclidine and disruption of prepulse inhibition. The dorsal and ventral hippocampus receive serotonin projections predominantly from the median raphe nucleus and dorsal raphe nucleus, respectively. Therefore, we investigated the effect of local lesions of serotonin projections into the dorsal and ventral hippocampus on psychotomimetic drug-induced locomotor hyperactivity and prepulse inhibition. Male Sprague-Dawley rats were anaesthetized with pentobarbitone and stereotaxically microinjected with 5 microg of the serotonergic neurotoxin 5,7-dihydroxytryptamine into either the dorsal or the ventral hippocampus. Two weeks after surgery, dorsal hippocampus-lesioned rats showed a 100% enhancement of the locomotor hyperactivity caused by phencyclidine treatment and a slight but significant reduction of the effect of amphetamine. Prepulse inhibition was significantly disrupted in lesioned rats and serotonin levels in the dorsal hippocampus were reduced by 80%. Rats with lesions of the ventral hippocampus showed 85% depletion of serotonin and partial disruption of prepulse inhibition, but no significant changes in the effect of phencyclidine or amphetamine. These results suggest that serotonin projections from the median raphe nucleus to the dorsal hippocampus play an important role in locomotor hyperactivity and prepulse inhibition in rats, animal models of aspects of schizophrenia. This suggests that these serotonin projections may be involved in the pathophysiology of schizophrenia symptomology.

Abstract
Lesions of basal forebrain cholinergic neurons by intracerebroventricular (i.c.v.) injections of 192 IgG-saporin increased the locomotor response to 0.5 and 1.5 mg/kg of D-amphetamine in adult rats [A. Mattsson, S.O. Ogren, L. Olson, Facilitation of dopamine_mediated locomotor activity in adult rats following cholinergic denervation, Exp Neurol. 174 (2002) 96-108.]. In the present study, adult male rats were subjected to bilateral injections of 192 IgG-saporin either into the septum (Sp), the nucleus basalis magnocellularis (Nbm), both structures (SpNbm) or i.c.v. Locomotor activity was assessed in the home cage 23 days after surgery, and, subsequently, thrice after an intraperitoneal injection of D-amphetamine (1 mg/kg) and twice after an injection of cocaine (15 mg/kg). Analysis of AChE-stained material showed that Sp lesions induced preferentially hippocampal denervation, Nbm lesions induced preferentially cortical denervation, while both SpNbm and i.c.v. lesions deprived the hippocampus and the cortex of almost all AChE-positive reaction products. The spontaneous and drug-induced locomotor activity of all lesioned rats did not differ significantly from that of control rats, except in rats subjected to i.c.v. injections, in which the locomotor response was significantly increased after the second administration of cocaine. In addition, in Nbm and SpNbm rats, the locomotor reaction to cocaine was weaker right after the second injection. The present results do not confirm the report by Mattsson et al. on the potentiation of amphetamine-induced locomotion by i.c.v. injections of 192 IgG-saporin, but suggest that cocaine-induced locomotion can be increased by such lesions and, to some respect, attenuated by cholinergic damage in the Nbm.

Abstract
The present study was designed to determine how 5-HT(1B) receptor ligands affected the development or the expression phase of sensitization to the amphetamine-induced locomotor response in mice. Mice were treated repeatedly (for 5 days) with amphetamine (2.5 mg/kg) in combination with either vehicle, N-[3-[3-(dimethylamino)ethoxy]-4-methoxyphenyl]-2'-methyl-4'-(5-methyl-1,2,4-oxadiazol-3-yl)-[1,1'-biphenyl]-4-carboxamide hydrochloride (SB 216641; an antagonist of 5-HT(1B) receptors), 3-(1,2,5,6-tetrahydro-4-pyridyl)-5-propoxypyrrolo[3,2-b]pyridine (CP 94,253; an agonist of 5-HT(1B) receptors), or SB 216641+CP 94,253; afterwards, on day 10, they received a challenge dose of amphetamine (2.5 mg/kg). In another experiment, mice were given either vehicle or amphetamine (2.5 mg/kg) for 5 days, and were then challenged with amphetamine (2.5 mg/kg) in combination with vehicle, SB 216641, or CP 94,253 on day 10. Locomotor hyperactivity induced by acute administration of amphetamine (day 1) was dose-dependently inhibited by SB 216641 and enhanced by CP 94,253, but not affected by a combination of SB 216641+CP 94,253. The 5-HT(1B) receptor ligands affected similarly the behavioral response to the challenge dose of amphetamine on day 10 (ca. 55-110% more potent than the response to its first administration) when they were combined with the psychostimulant during the development phase (days 1-5) of sensitization. On the other hand, neither SB 216641 nor CP 94,253 administered together with the challenge dose of amphetamine (day 10) affected its behavioral hyperactivity effect in mice treated repeatedly (days 1-5) with the psychostimulant alone. Our results suggest that 5-HT(1B) receptors may play a permissive role in the development, but not expression, of behavioral sensitization, as well as in the acute locomotor response to amphetamine in mice.
