| Outline of Final Research Achievements |
Brain tissues of autistic patients and controls with no neurological symptoms were obtained through the Autism Tissue Program. Using Paraffin slice, we found increased number of hematopoietic prostaglandin D synthase (HPGDS)-positive microglia in the frontal lobe of the autistic brain. Quantitative RT-PCR revealed that the levels of HPGDS mRNA, IL-6 mRNA and TGF-beta1 mRNA were significantly higher in autistic brains than control brains, in the frontal lobe, but not in the occipital lobe. Using primary cultured neuron, we fined that the number of dendrite is significantly increased by PGD2 receptor agonist. Many data suggested the frontal lobe dysfunction in autistic patients. Our findings were compatible those findings and may lead understanding the pathogenesis of autism.
