Current State of Modeling Human Psychiatric Disorders Using Zebrafish

Area of Science:

• Neuroscience
• Psychiatry
• Animal Models
• Translational Research

Background:

• Psychiatric disorders are prevalent brain pathologies requiring effective clinical diagnoses.
• Reliable animal models with relevant endpoints are crucial for understanding and treating these conditions.
• Zebrafish (Danio rerio) exhibit conserved complex behaviors relevant to human psychiatric disorders.

Purpose of the Study:

• To critically discuss the utility and challenges of using zebrafish to model human psychiatric disorders.
• To highlight areas for further research to improve zebrafish as a translational model for CNS diseases.
• To summarize recent molecular biology advancements in zebrafish for disease modeling.

Main Methods:

• Review and critical discussion of existing literature on zebrafish models for psychiatric disorders.
• Analysis of behavioral and physiological endpoints in zebrafish relevant to human neurobehavioral domains.
• Summary of recent molecular biology developments in the context of zebrafish CNS disease modeling.

Main Results:

• Zebrafish display evolutionarily conserved behaviors that parallel those observed in rodents and humans.
• Despite advantages, challenges exist in utilizing zebrafish for modeling the complexity of psychiatric disorders.
• Recent molecular advancements support the potential of zebrafish in translational neuroscience research.

Conclusions:

• Zebrafish represent a valuable model organism for psychiatric disorder research, offering conserved behaviors.
• Addressing current challenges is essential to fully leverage zebrafish for translational CNS disease modeling.
• Increased utilization of zebrafish is encouraged to advance our understanding of brain pathologies.
