A novel double-hit animal model of schizophrenia: behavioural assessment in male and female mice
(Elsevier, 2020-11-17)
Background: A growing body of evidence support that maternal prenatal infections represent a risk factor for schizophrenia in offspring. Moreover, stressful events during critical neurodevelopmental periods, such as ...
Differential brain ADRA2A and ADRA2C gene expression and epigenetic regulation in schizophrenia. Effect of antipsychotic drug treatment
(Springer Nature, 2021-12-20)
[EN] Postsynaptic alpha(2A)-adrenoceptor density is enhanced in the dorsolateral prefrontal cortex (DLPFC) of antipsychotic-treated schizophrenia subjects. This alteration might be due to transcriptional activation, and ...
Opposite Alterations of 5¬HT2A Receptor Brain Density in Subjects with Schizophrenia: Relevance of Radiotracers Pharmacological Profile
(Springer, 2021-05-20)
The status of serotonin 5HT2A receptors (5HT2ARs) in schizophrenia has been controversial. In vivo positron emission
tomography neuroimaging and in vitro post-mortem binding studies have reported conflicting results about ...
Cannabis use selectively modulates circulating biomarkers in the blood of schizophrenia patients
(Wiley, 2022-11)
Cannabis use disorder is frequent in schizophrenia patients, and it is associated with an earlier age of onset and poor schizophrenia prognosis. Serotonin 2A receptors (5-HT2AR) have been involved in psychosis and, like ...
Behavioural Evaluation of a Translational Animal Model of Schizophrenia
(Wiley, 2018-08)
Schizophrenia (SZ) is a chronic and disabling psychiatric disorder affecting about 1% of the population worldwide. Schizophrenia comprises positive and negative symptoms as well as cognitive deficits. Epidemiological and ...
Characterization of dopamine D2 receptor coupling to G proteins in postmortem brain of subjects with schizophrenia
(Springer, 2021-08)
Background: Alterations of dopamine D-1 (D1R) and D-2 receptor (D2R) are proposed in schizophrenia but brain neuroimaging and postmortem studies have shown controversial results in relation to D1R and D2R density. Besides, ...
Inhibition of Prolyl Oligopeptidase Restores Prohibitin 2 Levels in Psychosis Models: Relationship to Cognitive Deficits in Schizophrenia
(MDPI, 2023-03-23)
Cognitive impairment represents one of the core features of schizophrenia. Prolyl Oligopeptidase (POP) inhibition is an emerging strategy for compensating cognitive deficits in hypoglutamatergic states such as schizophrenia, ...
Behavioral, neurochemical and morphological changes induced by the overexpression of munc18-1a in brain of mice: relevance to schizophrenia
(Nature Publishing Group, 2013-01)
Overexpression of the mammalian homolog of the unc-18 gene (munc18-1) has been described in the brain of subjects with schizophrenia. Munc18-1 protein is involved in membrane fusion processes, exocytosis and neurotransmitter ...
The Role of α-Synuclein in the Regulation of Serotonin System: Physiological and Pathological Features
(MDPI, 2023-02-13)
In patients affected by Parkinson’s disease (PD), up to 50% of them experience cognitive changes, and psychiatric disturbances, such as anxiety and depression, often precede the onset of motor symptoms and have a negative ...
Pimavanserin exhibits serotonin 5-HT 2A receptor inverse agonism for G αi1 - and neutral antagonism for G αq/11 -proteins in human brain cortex
(Elsevier, 2020-06-07)
[EN] Pimavanserin is claimed as the first antipsychotic drug that shows selectivity for serotonin 5- HT 2 receptors (5-HT 2 Rs) and lacks of affinity for dopamine D 2 receptors (D 2 Rs). Cell-based func- tional assays ...
