Prenatal Stress Induces Changes in Behavior, HPA Axis, Inflammation, and Oxidative Stress in Adult Rats Offspring

Area of Science:

• Neuroscience
• Psychiatry
• Endocrinology

Background:

• Prenatal stress is linked to psychiatric disorders.
• These disorders involve inflammation, oxidative stress, and HPA axis dysregulation.

Purpose of the Study:

• To investigate prenatal stress effects on behavior, inflammation, oxidative stress, and HPA axis in dams and offspring.
• To evaluate lithium's therapeutic potential.

Main Methods:

• A prenatal chronic unpredictable stress model was used in Wistar rats.
• Offspring were treated with lithium or saline postnatally.
• Behavioral tests (open field), and biochemical analyses (oxidative stress, inflammation, HPA axis) were performed.

Main Results:

• Prenatal stress induced hyperactivity and increased pro-inflammatory cytokines, oxidative damage, and HPA axis hormones in female offspring.
• Lithium administration mitigated these biochemical alterations.

Conclusions:

• Prenatal stress induces persistent behavioral, inflammatory, oxidative, and HPA axis changes in offspring.
• These alterations may contribute to psychiatric disorder development.
• Lithium shows potential in ameliorating stress-induced biochemical changes.
