| Research Abstract |
1) Role of Desert hedgehog in development and differentiation of perineurium
We confirmed expression of mRNA of Desert hedgehog (Dhh), and patched 2 in peripheral nerves of wild type mice. Expression of these molecules decreased after nerve injury, then gradually increased in regenerating phase. These results suggest that Dhh-Patched 2 pathway may play and role of maintenance of perineurium, and regeneration.
2) Role of Dhh in the central nervous system
We have analyzed motor, sensory, memory and emotional function of Dhh knockout mice. As a result, Dhh knockout mice had emotional disorders (depression and anxiety). These results suggest that Dhh may be associated with emotion.
3) Establishment of the new disease concept: Minifascicular neuropathy with gonadal dysgenesis
We found the second case of minifascicular neuropathy with 46, XY gonadal dysgenesis.
4) Dhh transgenic mice
We succeeded in development of Dhh transgenic mice/
