Psychosis: Pathophysiology of Schizophrenia and Other Psychotic Disorders01:27

Psychosis: Pathophysiology of Schizophrenia and Other Psychotic Disorders

1.2K
Schizophrenia is a neurodevelopmental disorder whose origins are rooted in complex genetic components. Despite our burgeoning understanding, the pathophysiology of this disorder remains incompletely deciphered.
Researchers have identified genetic factors that increase susceptibility to schizophrenia, underscoring the intricate interplay between genetics and environment in disease development. At the core of schizophrenia's pathophysiology is excessive dopaminergic neurotransmission within...

Biological Causes of Schizophrenia

198
Schizophrenia, a severe psychiatric disorder, arises from a complex interplay of biological factors, including genetic predisposition, structural brain abnormalities, neurotransmitter dysregulation, and developmental irregularities. These factors collectively contribute to the onset and progression of the disorder, which typically manifests in late adolescence or early adulthood.
Genetic Factors in Schizophrenia
The genetic basis of schizophrenia is strongly supported by family and twin...

EPS and iPS Cells in Disease Research

Embryonic and induced pluripotent stem cells are excellent models for disease research because of their ability to self-renew and differentiate into most cell types. Somatic cells from a patient are isolated and reprogrammed into induced pluripotent stem cells or iPSCs. These iPSCs are later differentiated into the desired cell type, which mirrors the diseased cell of the patient. In this way, disease models have been created for investigating diseases such as Down syndrome, type I diabetes,...

Psychological and Sociocultural Causes of Schizophrenia

233
Schizophrenia, a complex psychiatric disorder, has been historically misunderstood. Early psychological theories attributed its origins to childhood trauma and unresponsive parenting. However, contemporary research largely rejects these notions, favoring the vulnerability-stress hypothesis. This model proposes that individuals with a genetic predisposition to schizophrenia may develop the disorder following exposure to significant environmental stressors. Notably, studies on high-risk...

Schizophrenia

334
Schizophrenia, a term introduced by Swiss psychiatrist Eugen Bleuler in 1911, describes a severe psychological disorder marked by profound disruptions in attention, thought processes, language, emotion, and interpersonal relationships. The core feature of schizophrenia is psychosis — a state characterized by a fundamental detachment from reality. This disconnection manifests through distorted logic, impaired perception, and atypical behavior, severely affecting the lives of those...

Area of Science:

  • Neuroscience
  • Genetics
  • Cell Biology

Background:

  • Schizophrenia (SZ) is a common functional psychosis with complex behavioral symptoms and brain function abnormalities.
  • Genome-wide association studies (GWAS) have identified numerous schizophrenia-associated loci, but their direct biological relevance remains unclear.
  • Developing cellular models with SZ-associated variations is a key research focus in the post-GWAS era.

Purpose of the Study:

  • To systematize and classify cellular models of schizophrenia.
  • To evaluate the complexity and validity of these models for understanding schizophrenia-related phenotypes.
  • To bridge the gap between genetic findings and biological mechanisms in schizophrenia.

Main Methods:

  • Review and classification of existing cellular models for schizophrenia research.
  • Integration of data from CRISPR/Cas9 gene editing and brain organoid technologies.
  • Analysis of model utility in studying transcriptional, oxidative, and synaptic dysregulation.

Main Results:

  • Cellular models offer a platform to investigate schizophrenia-associated variations.
  • CRISPR/Cas9 and brain organoids facilitate the construction of sophisticated cellular models.
  • These models can elucidate links between genetic loci and schizophrenia phenotypes.

Conclusions:

  • Cellular models are essential for dissecting the biological underpinnings of schizophrenia.
  • The advancement of gene-editing and organoid technologies enhances model development.
  • Systematic classification aids in selecting appropriate models for specific research questions in schizophrenia.
