   Abstract:
   An immune challenge during the neonatal period can significantly affect the development of the nervous and immune systems, such that long-term abnormalities in immune function and behavior persist into adulthood. Given that immune activation and individual cytokines have been linked to the etiology of many developmental neuropsychiatric disorders, a complete characterization of the neonatal immune response within the brain is warranted. In this study, rats were treated peripherally on postnatal day (P) 4 with either a live Escherichia coli (E. coli) infection or lipopolysaccharide (LPS), two common models of neonatal immune activation. Inflammatory gene expression was measured within the hippocampus 2 and 24h later. We determined that E. coli and LPS produce very distinct inflammatory profiles within the brain. Infection with E. coli produced a robust, yet relatively IL-1 pathway focused activation of the neonatal immune system within the brain, while LPS produced a very broad and robust immune response within the brain. This analysis also identified common inflammatory genes up-regulated by both E. coli and LPS treatment.
