In the development of molecular therapeutics that ameliorate α-dystroglycan (α-DG)-associated diseases, we identified the glycan unit ribitol 5-phosphate (Rbo5P) in α-DG and showed that enzyme activities of α-DG-associated diseases are involved in the synthesis of tandem Rbo5P. We also found that FKTN and FKRP can transfer GroP to O-mannosyl glycans by using CDP-glycerol (CDP-Gro) as a donor substrate. The analysis of mouse models of α-DG-associated diseases indicated that spatiotemporal persistence of functionally glycosylated α-DG may be crucial for brain development. These findings provide insight into pathogenesis and therapeutic strategies in α-DG-associated diseases.

We perform case-control association studies in Parkinson disease (PD) employing whole-exome sequence analysis to discover rare PD susceptibility variants. Employing a novel bioinformatics approach using GWAS loci in PD along with in vitro functional studies and MPTP mouse model analysis, we identified a novel drug candidate for the prevention of neurodegeneration in PD. We also identified genetic factors responsible for the individual difference of the effects of zonisamide by using GWAS.

In the field of molecular genetics, we have developed the Genomic Medicine Research Support Center, and introduced next-generation sequencers to conduct comprehensive genome analyses to elucidate molecular bases of various neurological diseases. Regarding monogenic neurologic diseases, we conduct pedigree analyses in various neurological diseases including epilepsy, multiple system atrophy, amyo-trophic lateral sclerosis, hereditary spastic paraplegia, spinocerebellar atrophy, and adrenoleukodystrophy. As for sporadic neurologic diseases, we perform case-control association studies in multiple system atrophy and amyotrophic lateral sclerosis to identify genetic factors underlying these diseases. We identified that ALS patients with multiple rare deleterious variants in causative genes for ALS have earlier ages at onset. On the basis of the findings that mutations in COQ2 are associated with familial as well as sporadic multiple system atrophy, we are conducting an investigator-initiated clinical trial using coenzyme Q10 for patients with multiple system atrophy. We also identified expanded intronic TTTCA and TTTTA repeats in three independent genes in patients with benign adult familial myoclonic epilepsy, which postulate a new disease mechanism in epilepsy.

The human neurophysiology section specializes in studying the physiology of the human motor and sensory systems in awake healthy volunteers and the pathophysiology of neurological disorders using several non-invasive physiological methods, such as TMS, EEG, MEG, fMRI, NIRS and EOG. Our final goal is to devise new therapeutic techniques for intractable neurological disorders. To this end, the work extends from the study of spinal systems to basal ganglia and cerebral cortex. We are especially interested in plasticity induction by non-invasive brain stimulation (NIBS) techniques, offering potential for clinical application. Our lab has a long experience in the use of transcranial magnetic stimulation (TMS) which is able to stimulate neurons in intact human brain and has devised a highly effective repetitive TMS method to induce long-term effects (quadripulse stimulation, QPS). We have recently started a clinical trial of repetitive TMS to treat patients with Parkinson’s disease.

In the field of neuromuscular diseases, we provide pathological diagnosis of biopsied materials from patients with myopathy or neuropathy. We also provide autoantibody testing for anti-ganglioside antibodies, muscle specific antibodies and para¬neoplastic neurological antibodies. In research field, using biopsied muscles and collected serum samples, we have been studying the mechanisms of inflam¬matory myopathies from the view points of patho¬logical changes, myositis specific autoantibodies, serum cytokines, and expression profiling of muscle samples. Our aim is to increase understanding of the etiology and pathogenesis of neuromuscular diseases.

In the biochemistry laboratory, autopsy brain analysis of Alzheimer's disease and Lewy body disease was performed, and a new gene involvement was discovered. Chronic cerebral hypoperfusion model mouse was created and its characteristics were analyzed, the technology was applied to analyze amyloid β metabolism under chromic hypoperfusion. On the other hand, we analyzed J-ADNI cohort data. Comparison with US-ADNI data revealed compatibility between the two cohorts. The influence of sex difference and education level, and the influence of serum calcium level was discovered. Other activities include development of new imaging techniques using Raman microspectroscopy. We visualized globo-triaosylceramide distribution within peripheral nerve of Fabry’s disease patient in non-labeled manner. Recently we also applied this technique to observe lipid accumulation in rimmed vacuoles from inclusion body myositis patients. We also developed a new optical sensor device detecting biomarkers for Alzheimer’s disease using nanoimprint lithography (NIL)-based two-dimensional photonic crystal (2D-PhC). In a pilot study quantifying Aβ in CSF and serum samples, our sensor achieved higher sensitivity than conventional ELISA. We also developed a novel preanalytical sample handling protocol for high sensitivity measurement. We are also participating in observational studies of preclinical Alzheimer's disease (AMED Preclinical research) and DIAN-J studies.
