| Outline of Final Research Achievements |
The KK rat, induced mutant rat strain, shows gait abnormality of hind limb and was histopathologically diagnosed as neuroaxonal dystrophy (NAD). We identified a novel mutation in kk gene (unpublished data) as the most likely causative gene of the KK rat. We also found that axonal spheroids were located mainly within the sensory systems, and the axonal transport deficits and synaptic dysfunction may involved in spheroid formation and axonal degeneration in the KK rat. The kk gene has not yet been reported as a causative gene of NAD or other neurodegenerative diseases in mammals. Our results highlighted the importance of the KK rat as an animal model of NAD.
