Research Projects

The molecular mechanism of neurodegenerative diseases such as motor neuron disease (amyotrophic lateral sclerosis, ALS) remains unknown. Therefore, therapeutic strategy has not been established. Our laboratory aims to elucidate the mechanism of onset and progression of motor neuron disease, which have been shown to be derived from the pathological changes within different cell types; motor neurons and glial cells. We will analyze inherited ALS, using mouse, cell culture, and in vitro system as models. Based on these studies, we expect to design the therapeutic interventions for the sporadic ALS patients in future.
