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.

Paranoia and risk of personality disorder in the general population

TL;DR: Paranoia seems to either augment the risk for, or be part of, PD/BPD in the general population, and holds true for both personality outcomes (PD and BPD).

Schizophrenia: The new etiological synthesis

TL;DR: In this article , the authors discuss the constellation of evolutionary hypotheses for schizophrenia, highlighting the lack of empirical support for most existing evolutionary hypotheses-with the exception of the relatively well supported evolutionary mismatch hypothesis.

Sensory Neuroscience: Linking Dopamine, Expectation, and Hallucinations

TL;DR: A new study has now uncovered a dopamine-dependent mechanism that explains why psychotic patients experience hallucinations.
Journal ArticleDOI

Illusions, Delusions, and Your Backwards Bayesian Brain: A Biased Visual Perspective

TL;DR: In this article, the role of cortico-cortical feedback in the visual system is explored, and the neuromodulator, dopamine, may be a crucial link between neural circuits performing Bayesian inference and the perceptual idiosyncrasies of people with schizophrenia.

Circuit-Based Approaches to Understanding Corticostriatothalamic Dysfunction Across the Psychosis Continuum

TL;DR: In this article , the role of corticostriatothalamic (CST) circuits in the pathogenesis of schizophrenia was investigated. But the mechanisms driving dopaminergic dysfunction in psychosis remain unclear, and the results of preclinical models of CST dysfunction were not supported by evidence from human resting-state functional magnetic resonance imaging studies conducted across the psychosis continuum.

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.

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.

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.

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.
