Abstract
Second-generation antipsychotics are widely used for the treatment of schizophrenia. Aripiprazole (ARI) is classified as a third-generation antipsychotic drug with a high affinity for dopamine and serotonin receptors. It is considered a dopamine-system stabilizer without severe side effects. In some patients the response to ARI treatment is inadequate and they require an effective augmentation strategy. It has been found that the response to the drug and the risk of adverse metabolic effects can be related to gene polymorphisms. A reduced dose is recommended for CYP2D6 poor metabolizers; moreover, it is postulated that other polymorphisms including CYP3A4, CYP3A5, ABCB1, DRD2, and 5-HTRs genes influence the therapeutic effect of ARI. ARI can increase the levels of prolactin, C-peptide, insulin, and/or cholesterol possibly due to specific genetic variants. It seems that a pharmacogenetic approach can help predict drug response and improve the clinical management of patients with schizophrenia.

Abstract
Second generation antipsychotic drugs including aripiprazole, olanzapine and risperidone are prescribed increasingly (mostly off-label) to treat various mental disorders in children and adolescents. Early treatment with antipsychotics during this period may have long-lasting behavioural impacts, but to date there have been only limited investigations. Maternal infection could be implicated in the aetiology of various mental disorders including schizophrenia. Exposure of pregnant rodents to polyriboinosinic-polyribocytidylic acid (Poly I:C) causes schizophrenia-like behavioural abnormalities and neurodevelopmental conditions such as autism spectrum disorders in offspring. This study, using a Poly I:C rat model, investigated the long-lasting effects of early aripiprazole, olanzapine and risperidone treatment in the childhood/adolescent period (postnatal day 22-50) on adult behaviours of male rats. The study showed that early treatment with three antipsychotics had different effects on long-term behavioural changes in adults. Prenatal Poly I:C exposure (5 mg/kg) at gestation day 15 caused deficits in pre-pulse inhibition and social interaction, as well as cognitive impairments, that could be partially improved by early antipsychotic treatment in the juvenile period. Early antipsychotic treatment during the childhood-adolescent period resulted in similar long-lasting effects on pre-pulse inhibition, anxiety- and depressive-related behaviours in both Poly I:C and healthy (control) male rats. Overall, these results suggest that both prenatal Poly I:C exposure and early antipsychotic treatment in the childhood/adolescent period had long-lasting effects on adult behaviours of male rats, while early antipsychotic treatment could partly prevent the onset of behavioural abnormalities resulting from prenatal insult.

Abstract
Previous work shows that repeated administration of several commonly used antipsychotic drugs, such as olanzapine (OLZ) over several days, induces an enhanced disruption of conditioned avoidance response (CAR) (termed antipsychotic sensitization) in normal adolescent and adult rats. However, it is unclear whether the same phenomenon can also be demonstrated in rat models of schizophrenia. The present study investigated OLZ sensitization in a combined maternal immune activation (MIA) and repeated maternal separation (RMS) model of schizophrenia. Sprague-Dawley male rats were first subjected to an early prenatal exposure to polyinosinic:polycytidylic acid (PolyI:C) on gestation days 13 (4 mg/kg, iv) and 15 (6 mg/kg, iv). They were then repeatedly separated from their mothers for 3 h daily during the first two weeks of postpartum. After they became adolescent (on postnatal day, PND 43), acute and OLZ sensitization effects in the CAR model was assessed. Adolescent MIA rats showed an impaired acquisition of conditioned avoidance response, but displayed a normal acute OLZ-induced avoidance suppression and OLZ sensitization effect. In adulthood (PND 81), MIA rats again showed an impairment in the acquisition of CAR. However, they showed a reduced response to OLZ (1.0 mg/kg; sc) treatment during the repeated drug test days, indicating a disruption of the induction of OLZ sensitization. In the OLZ sensitization challenge test, both MIA and control rats exhibited a robust and similar sensitization effect. In both adolescence and adulthood, RMS alone had no effect on any of the behavioral outcomes, and combined MIA-RMS even abolished the MIA alone-induced disruption of avoidance acquisition and the induction of OLZ sensitization. These results indicate that MIA disrupts associative learning and may reduce antipsychotic efficacy in the early stage of OLZ treatment. RMS does not appear to affect associative learning and behavioral responses to OLZ, and may possibly attenuate MIA-induced deficits. Our findings demonstrate that OLZ sensitization is a robust phenomenon but its magnitude can be altered by early MIA.

Abstract
Postmortem studies suggest that schizophrenia is associated with abnormal expression of specific GABAA receptor (GABAAR) α subunits, including α5GABAAR. Positron emission tomography (PET) measures of GABAAR availability in schizophrenia, however, have not revealed consistent alterations in vivo. Animal studies using the GABAAR agonist [3H]-muscimol provide evidence that antipsychotic drugs influence GABAAR availability, in a region-specific manner, suggesting a potential confounding effect of these drugs. No such data, however, are available for more recently developed subunit-selective GABAAR radioligands. To address this, we combined a rat model of clinically relevant antipsychotic drug exposure with quantitative receptor autoradiography. Haloperidol (0.5 and 2 mg/kg/day) or drug vehicle were administered continuously to adult male Sprague-Dawley rats via osmotic mini-pumps for 28 days. Quantitative receptor autoradiography was then performed postmortem using the GABAAR subunit-selective radioligand [3H]-Ro15-4513 and the non-subunit selective radioligand [3H]-flumazenil. Chronic haloperidol exposure increased [3H]-Ro15-4513 binding in the CA1 sub-field of the rat dorsal hippocampus (p<0.01; q<0.01; d=+1.3), which was not dose-dependent. [3H]-flumazenil binding also increased in most rat brain regions (p<0.05; main effect of treatment), irrespective of the haloperidol dose. These data confirm previous findings that chronic haloperidol exposure influences the specific binding of non-subtype selective GABAAR radioligands and is the first to demonstrate a potential effect of haloperidol on the binding of a α1/5GABAAR-selective radioligand. Although caution should be exerted when extrapolating results from animals to patients, our data support a view that exposure to antipsychotics may be a confounding factor in PET studies of GABAAR in the context of schizophrenia.
