The Role of Genes, Stress, and Dopamine in the Development of Schizophrenia.

TLDR
A model is presented of how genes and environmental factors may sensitize the dopamine system so that it is vulnerable to acute stress, leading to progressive dysregulation and the onset of psychosis.

Dopamine, Psychosis, and Symptom Fluctuation: A Narrative Review

Gabriela Novak, +1 more
- 01 Sep 2022 - 
TL;DR: The aim of this paper is to address the potential role of dopamine in schizophrenia in general and, in particular, in the fluctuations in schizophrenia symptoms, and to review recent research into schizophrenia etiology.

Illness Phase as a Key Assessment and Intervention Window for Psychosis

TL;DR: In this paper , a phase-specific biomarkers of illness phase and brain development can be incorporated into current strategies for large-scale research and clinical programs implementing coordinated specialty care, highlighting working memory and D1 dysfunction as early treatment targets.
Journal ArticleDOI

Efficacy, safety, and tolerability of ulotaront (SEP-363856, a trace amine-associated receptor 1 agonist) for the treatment of schizophrenia and other mental disorders: a systematic review of preclinical and clinical trials

TL;DR: In this paper , a systematic review of the available evidence on a TAAR1 agonist, ulotaront, as a treatment for schizophrenia was conducted, and three clinical, two comparative, and five preclinical studies were identified.
Journal ArticleDOI

Psychophysiological stress-reactivity in clinical and non-clinical voice-hearers.

TL;DR: In this paper, the authors investigated whether dysregulated psychophysiological stress-reactivity is specifically associated with auditory verbal hallucinations (AVHs) or psychosis more generally by comparing voice-hearers with and without a need for care.

Presynaptic Gq-coupled receptors drive biphasic dopamine transporter trafficking that modulates dopamine clearance and motor function

TL;DR: In this paper, the authors leveraged chemogenetics and conditional gene silencing and found that presynaptic Gq-coupled receptor activation, induced by either hM3Dq or mGluR5 activation, drives biphasic DAT trafficking in striatum.

Biological insights from 108 schizophrenia-associated genetic loci

Stephan Ripke, +354 more
- 24 Jul 2014 - 
TL;DR: Associations at DRD2 and several genes involved in glutamatergic neurotransmission highlight molecules of known and potential therapeutic relevance to schizophrenia, and are consistent with leading pathophysiological hypotheses.
Journal ArticleDOI

KEGG as a reference resource for gene and protein annotation

TL;DR: The KEGG GENES database now includes viruses, plasmids, and the addendum category for functionally characterized proteins that are not represented in complete genomes, and new automatic annotation servers, BlastKOalA and GhostKOALA, are made available utilizing the non-redundant pangenome data set generated from theGENES database.
Journal ArticleDOI

Clozapine for the treatment-resistant schizophrenic. A double-blind comparison with chlorpromazine

TL;DR: In this relatively brief study, the apparently increased comparative risk of agranulocytosis requires that the use of clozapine be limited to selected treatment-resistant patients.
Journal ArticleDOI

The NHGRI GWAS Catalog, a curated resource of SNP-trait associations

TL;DR: A number of recent improvements to theNHGRI Catalog of Published Genome-Wide Association Studies are presented, including novel ways for users to interact with the Catalog and changes to the curation infrastructure.

Stress signalling pathways that impair prefrontal cortex structure and function

TL;DR: Recent research has provided clues as to why genetic or environmental insults that disinhibit stress signalling pathways can lead to symptoms of profound prefrontal cortical dysfunction in mental illness.
