Abstract [en]

Maternal care is crucial for infants and profoundly affects their responses to different kinds of stressors. Here, we examined how maternal separation affects inflammatory gene expression and the corticosterone response to an acute immune challenge induced by lipopolysaccharide (LPS; 40 µg/kg ip) in mouse pups, 8–9 days old. Maternal separation initially attenuated LPS-induced hypothalamic pro-inflammatory gene expression, but later, at 3 h after immune challenge, robustly augmented such gene expression and increased serum corticosterone levels. Providing the pups with a warm and soft object prevented the separation-induced augmented hypothalamic-pituitary-adrenal (HPA)-axis response. It also prevented the potentiated induction of some, but not all, inflammatory genes to a similar extent as did the dam. Our results show that maternal separation potentiates the inflammatory response and the resulting HPA-axis activation, which may have detrimental effects if separation is prolonged or repeated.
