| Research Abstract |
It is known that child abuse is a risk factor for depression. To elucidate the mechanisms and to develop the treatments are required. Rats were subjected to aversive foot shock (FS) during the third week of the postnatal period (3wFS
group). 3wFS group displayed depressive-like behavior in adulthood and showed the increased protein levels of tryptophan hydroxylase 2 in the dorsal raphe nucleus which is a origin of serotonergic neurons. These adverse effects were partly reversed by repeated administration of selective serotonin reuptake inhibitor (SSRI). Thus, it is possible that SSRI administration could partly attenuate the adverse effects of child abuse.
