Outline of Final Research Achievements

We performed first clinical PET studies using [11C]ITMM for imaging metablotropic glutamate receptor type 1 (mGluR1) in the human brain. [11C]ITMM-PET provided acceptable dosimetry and pharmacological safety. The [11C]ITMM binding in brain regions was well correspond to the mGluR1 distribution in the brain, suggesting that [11C]ITMM-PET becomes a new tool for pathphysiological studies of neurodegenerative disease.
In healthy subjects [11C]ITMM binding increased in several brain regions of the elderly subjects. In patients with hereditary and sporadic cerebellar ataxia, the [11C]ITMM binding significantly decreased in cerebellar region compared with age-matched healthy subjects. The measurement of mGluR1 availability would be more sensitive than morphological measure by MRI. In Parkinson’s disease the binding decreased in cerebellum and temporal and parietal lobes. Preliminarily mGluR1 availability were regionally changed in the brain of patients with Alzheimer’s disease and epilepsy.
