Research Abstract

We have found serotonin transporter (SERT) binding was significantly lower throughout the brain in autistic individuals compared with healthy controls by PET study. To clalify mechanism underlying, we have analyzed gene and postmortem brain of autistic subjects and the controls. As results, we have found change of SERT-related gene expression in the study. However, there was no difference in SERT expression of postmortem brains between them. Taken together, SERT dysfunction in autistic brain may be caused by intracellular trafficking dysfunction but not expression impairment.
