In the present study, we compared the expression patterns of neuritin mRNA in the dentate gyrus of hippocampal formation following single (1×ECS) or repeated elctroconvulsive seizures (8×ECS) treatments to the rat. The expression of neuritin mRNA was transiently increased, and returned to basal level within 12 hours after 1×ECS. Whereas initial induction of neuritin mRNA was similarly seen, these increased mRNA level was maintained for 24 hours in 8×ECS group. In contrast, induction profile of BDNF was similar following 1× and 8×ECS. These results suggest that regulation of neuritin expression may be plastically changed by repeated ECS treatment.
