Prenatal Zinc Supplementation Ameliorates Hippocampal Astrocytes Activation and Inflammatory Cytokines Expression Induced by Lipopolysaccharide in a Rat Model of Maternal Immune Activation.

Schizophrenia is a chronic and disabling psychiatric disorder, affecting an estimated one percent of the world's population. To date, the biological mechanisms underlying this mental disorder remain largely elusive, however, research has demonstrated the involvement of both genetic and environmental factors. Of environmental factors, gestational exposure to rubella, influenza, and genital-reproductive infections have gained particular interest among researchers. Based on this evidence, in the present study, we used an animal model of schizophrenia and showed the beneficial effect of zinc supplementation during pregnancy to protect against LPS-induced inflammation in the hippocampus of adult offspring. Collectively, our study provides support for the premise that early treatment might be a suitable option to prevent schizophrenia risk in progeny.
