Effect of prenatal LPS on vasopressin expression in the MeA and BST. Means (+ SEM) of the number of AVP mRNA-labeled cells in the MeA and BST. #: Overall, males had significantly more AVP mRNA-labeled cells than did females (ANOVA, p < 0.0001 for MeA as well as BST). (I): There was a significant sex X treatment interaction: LPS treatment reduced the number of cells in the MeA and BST in males but not in females (ANOVA, p < 0.04 and p < 0.03 for MeA and BST, respectively). *: Planned comparison showed that LPS males had significantly fewer labeled cells than did Saline Males (Fisher’s PLSD, p < 0.02 and p < 0.005 for the MeA and BST, respectively).
