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 ...
NRN1 Gene as a Potential Marker of Early-Onset Schizophrenia: Evidence from Genetic and Neuroimaging Approaches
(MDPI, 2022)
Included in the neurotrophins family, the Neuritin 1 gene (NRN1) has emerged as an attractive candidate gene for schizophrenia (SZ) since it has been associated with the risk for the disorder and general cognitive performance. ...
The endocannabinoid system in mental disorders: Evidence from human brain studies
(Elsevier, 2018-07-17)
Mental disorders have a high prevalence compared with many other health conditions and are the leading cause of disability worldwide. Several studies performed in the last years support the involvement of the endocannabinoid ...
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, ...
The Role of the Dopamine System in Post-Stroke Mood Disorders in Newborn Rats
(MDPI, 2023-02-06)
Post-stroke mood disorders (PSMD) affect disease prognosis in adults. Adult rodent models underlie the importance of the dopamine (DA) system in PSMD pathophysiology. There are no studies on PSMD after neonatal stroke. We ...
The Matricellular Protein Hevin Is Involved in Alcohol Use Disorder
(MDPI, 2023-01-25)
Astrocytic-secreted matricellular proteins have been shown to influence various aspects of synaptic function. More recently, they have been found altered in animal models of psychiatric disorders such as drug addiction. ...
Long-term hippocampal interneuronopathy drives sex-dimorphic spatial memory impairment induced by prenatal THC exposure
(Nature, 2020-04)
Prenatal exposure to Delta(9)-tetrahydrocannabinol (THC), the most prominent active constituent of cannabis, alters neurodevelopmental plasticity with a long-term functional impact on adult offspring. Specifically, THC ...
Serotonin 5-HT2A receptor expression and functionality in postmortem frontal cortex of subjects with schizophrenia: Selective biased agonism via Gαi1-proteins
(Elsevier, 2019-12)
Serotonin 5-HT2A receptors (5-HT(2A)Rs) have been implicated in schizophrenia. However, postmortem studies on 5-HT(2A)Rs expression and functionality in schizophrenia are scarce. The 5-HT2AR mRNA and immunoreactive protein ...
Preclinical Evaluation of an Imidazole-Linked Heterocycle for Alzheimer’s Disease
(MDPI, 2023-09-25)
Humanity is facing a vast prevalence of neurodegenerative diseases, with Alzheimer’s disease (AD) being the most dominant, without efficacious drugs, and with only a few therapeutic targets identified. In this scenario, ...
