Animal models of postpartum depression revisited

Area of Science:

• Neuroscience
• Psychiatry
• Animal Models

Background:

• Postpartum depression (PPD) is a prevalent psychiatric complication with significant maternal and infant health impacts.
• Despite research, the detailed neurobiological mechanisms underlying PPD remain unclear.
• Animal models, particularly rodents, are vital for studying PPD's pathophysiology.

Purpose of the Study:

• To provide an updated review of current rodent models used in postpartum depression research.
• To highlight the contributions of these models to understanding PPD.
• To explore emerging models offering new perspectives on PPD pathophysiology.

Main Methods:

• Categorization of PPD models into two main groups: hormone manipulation and stress exposure.
• Description of various paradigms within each category reflecting PPD risk factors.
• Inclusion of emerging models for novel research avenues.

Main Results:

• Rodent models offer critical insights into the neurobiological underpinnings of PPD.
• Hormone manipulation and stress exposure models represent key approaches in PPD research.
• Emerging models are expanding the scope of PPD investigation.

Conclusions:

• Animal models are indispensable for advancing PPD research and developing therapeutic strategies.
• Continued development and application of diverse rodent models are essential for unraveling PPD.
• These models hold promise for identifying novel therapeutic targets for PPD.
