[Translational behavioral research using common marmosets in the psychiatric field]

Area of Science:

• Neuroscience
• Psychiatry
• Translational Research

Background:

• Drug discovery for psychiatric disorders faces challenges due to inadequate behavioral assays and animal models.
• The prefrontal cortex is implicated in the pathophysiology of psychiatric conditions, making primates valuable research subjects.

Purpose of the Study:

• To review the current status and future prospects of translational behavioral research using common marmosets for psychiatric disorders.
• To explore the utility of marmoset models in bridging the gap between preclinical research and clinical applications in psychiatry.

Main Methods:

• Review of existing literature on marmoset behavioral paradigms and their relevance to clinical tasks for schizophrenia and major depressive disorder.
• Assessment of the progress and limitations in developing marmoset models that mimic psychiatric disorder pathophysiology.

Main Results:

• Clinical laboratory tasks have been developed to objectively measure psychiatric symptoms like motivational deficits, negative affective bias, and cognitive impairments.
• Marmoset behavioral paradigms are being developed to correspond to these clinical tasks, advancing translational research.

Conclusions:

• Common marmosets, with their developed prefrontal cortex, are promising experimental animals for future psychiatric translational research.
• Despite progress, limitations remain in developing marmoset models that fully replicate the pathophysiology of psychiatric disorders, necessitating further research.
