Outline of Final Research Achievements |
The secreted glycoprotein Reelin is believed to play critical roles in the pathogenesis of several neuropsychiatric disorders. The highly basic C-terminal region (CTR) of Reelin is necessary for efficient activation of its downstream signaling. We found that CTR-dependent Reelin functions are required for some specific normal brain functions and that mice lacking the CTR recapitulate some aspects of neuropsychiatric disorders. We also identified ADAMTS-3 as the protease that cleaves and inactivates Reelin in the cerebral cortex and hippocampus. Cleavage by ADAMTS-3 is the major contributor of Reelin inactivation in vivo. Dendritic branching and elongation was increased in ADAMTS-3-deficient mice. Therefore, inhibition of ADAMTS-3 upregulates Reelin activity and may be a potential therapeutic strategy for the prevention or treatment of neuropsychiatric and neurodegenerative disorders.
