| Research Abstract |
We investigated the restorative processes after the chronic and acute cerebellar damages. Firstly, the restorations after chronic cerebellar damages were assessed in the cerebellar neurodegenerative mutant mice. We found that neurodegeneration of cerebellar cells was partially prevented by inhibition of inflammation, using an antibiotic, minocycline. Secondly, the restoration after acute cerebellar damage was examined by ablation of unilateral cerebellar hemisphere in mice and rats. Acute cerebellar damage resulted in severe ataxia just after the lesion. However, prominent functional recoveries were observed within two weeks after the lesion. During the recovery period, marked upregulation of brain-derived neurotrophic factor (BDNF) was observed in motor cortex and remaining cerebellar hemisphere. Blocking the BDNF neurotransmission delayed the functional recoveries. Since it is generally accepted that BDNF is upregulated after rehabilitation (exercise) in the brain, BDNF expression in the cerebellum and motor cortex facilitated by some appropriate rehabilitations may promote the recoveries from the cerebellar damages.
