Towards zebrafish models of personality disorders

Area of Science:

• Neuroscience
• Psychiatry
• Animal Models

Background:

• Personality disorders (PDs) are prevalent but poorly understood, diagnosed, and treated.
• Common PDs include antisocial, borderline, narcissistic, and paranoid disorders.
• Preclinical modeling of PDs is challenging due to complex, overlapping behaviors.

Purpose of the Study:

• To discuss the utility of zebrafish (Danio rerio) as translational models for PD research.
• To evaluate challenges and limitations in using zebrafish for PD modeling.
• To provide a framework for future research on PDs in zebrafish.

Main Methods:

• Paralleling clinical PD symptoms to zebrafish behavioral phenotypes.
• Identifying biomarkers and paradigms in zebrafish relevant to PD traits.
• Critically evaluating existing challenges and limitations of zebrafish models.

Main Results:

• Zebrafish exhibit behavioral phenotypes that can model key PD traits like impulsivity, aggression, and emotional dysregulation.
• Despite challenges, zebrafish provide a platform for elucidating neurobiological mechanisms underlying PDs.
• Zebrafish models can potentially accelerate translational research and therapeutic discovery for PDs.

Conclusions:

• Zebrafish represent a valuable complementary model for studying the neurobiology of personality disorders.
• Further research can overcome current limitations, enhancing zebrafish utility in PD translational modeling.
• This approach may significantly advance the understanding and treatment of personality disorders.
