PMID- 16891615 OWN - NLM STAT- MEDLINE DCOM- 20060920 LR - 20061115 IS - 0077-8923 (Print) IS - 0077-8923 (Linking) VI - 1071 DP - 2006 Jul TI - Developmental trauma is associated with behavioral hyperarousal, altered HPA axis activity, and decreased hippocampal neurotrophin expression in the adult rat. PG - 542-6 AB - Effects of early-life trauma on adult behavioral responses, corticosterone (CORT) concentration, and levels of nerve growth factor (NGF), brain-derived neutrophic factor (BDNF), and neurotrophin-3 (NT-3) in hippocampus and frontal cortex were investigated. Traumatized animals showed an increase in rearing in both the elevated plus maze and open field after adult restress, higher basal levels of CORT, lower levels of BDNF in dorsal hippocampus, and lower levels of NT-3 in dorsal and ventral hippocampus. Trauma-related behavioral hyperarousal and altered hypothalamic-pituitary-adrenal (HPA) axis activity may be mediated by decreases in hippocampal neurotrophin expression.
