Abstract

Alterations in immune function of various humoral and cellular factors, including chemokines, secondary to early stress may play a role in the enhanced vulnerability to psychiatric conditions in those with a history of childhood adversity. C57BL/6 (WT) mice and mice deficient for the chemokine receptor type 7 (CCR7-/-) were used to determine the effects of maternal separation on a range of behaviours and the biological stress response. Unpredictable maternal separation (MS) was conducted for 3h daily from postnatal day 1 to 14, with subsequent behavioural testing at 10 weeks of age. Corticosterone was quantified in 11-week-old mice. Maternally separated (MS) CCR7-/-, but not WT mice, display..
