Insights

Maternal immune activation during pregnancy can harm offspring neurodevelopment. Resveratrol (RSV) administration during this period significantly mitigated these negative effects, offering a potential therapeutic strategy for preventing psychiatric disorders.

Area of Science:

  • Neuroscience
  • Immunology
  • Pharmacology

Background:

  • Prenatal maternal immunological stress is linked to neurodevelopmental and psychiatric disorders in offspring.
  • The developing brain is particularly vulnerable to such stressors during critical neurodevelopmental periods.
  • Polyphenols, like resveratrol, possess antioxidant and anti-inflammatory properties, suggesting therapeutic potential.

Purpose of the Study:

  • To investigate the behavioral effects of maternal immune activation (MIA) induced by an H1N1-derived antigen in offspring.
  • To evaluate the protective efficacy of resveratrol (RSV) against MIA-induced neurodevelopmental and behavioral deficits.
  • To explore RSV as a potential therapeutic agent for preventing stress-induced psychiatric disorders.

Main Methods:

  • Maternal immune activation (MIA) was induced using an H1N1-derived antigenic solution.
  • Resveratrol (RSV) was administered to pregnant dams from embryonic day 14 (E14) to E19.
  • Offspring behavior was assessed in adulthood, including anxiety, risk assessment, memory, object recognition, and social interaction tests.
  • In vitro antioxidant capacity of RSV was evaluated, and its structure was characterized using infrared spectroscopy.

Main Results:

  • MIA induced significant behavioral changes in offspring, including anxiety, impaired memory and recognition, and social deficits resembling autism.
  • RSV administration during the MIA period effectively counteracted these harmful effects.
  • Adult offspring exposed to MIA and RSV treatment showed restored social behaviors, memory, and recognition, along with anxiolytic and antidepressant effects.

Conclusions:

  • Prenatal MIA significantly impacts offspring neurodevelopment and behavior, increasing the risk for psychiatric disorders.
  • Resveratrol demonstrates significant neuroprotective properties against MIA-induced developmental deficits.
  • RSV presents a promising therapeutic strategy for mitigating the adverse effects of prenatal neurodevelopmental stressors and preventing associated psychiatric conditions.
