Neonatal lipopolysaccharide treatment alters hippocampal neuroinflammation, microglia morphology and anxiety-like behavior in rats selectively bred for an infantile trait
Neonatal immune challenge increases anxiety-like behavior in a low-anxiety rat line. Neonatal immune challenge reduces anxiety-like behavior in a high-anxiety rat line. Neonatal immune challenge alters peripheral inflammation in a phenotypic-dependent manner. Sex and phenotype interact after neonatal LPS to alter anxiety-like behavior.
