Overview
Mermaid diagram (expand to render)
Osaka University (大阪大学, Ōsaka Daigaku) is one of Japan's premier national universities and a leading research institution in neuroscience and neurodegeneration. Located in Osaka, Japan's third-largest city, the university has grown from its origins as two precursor institutions (the Osaka Imperial University and the Osaka University of Foreign Studies) into a comprehensive research university with approximately 23,000 students across multiple campuses.
The university consistently ranks among the top 100 institutions globally for neuroscience research and has made significant contributions to understanding the molecular mechanisms underlying Alzheimer's disease, Parkinson's disease, and other neurodegenerative disorders. Osaka University researchers have been instrumental in advancing our understanding of protein aggregation, synaptic dysfunction, and neuroinflammation in neurodegenerative disease pathogenesis.
History
Osaka University traces its origins to the Osaka Imperial University, established in 1931. Over the past nine decades, the university has expanded its research capabilities and academic programs, establishing itself as a center of excellence in biomedical research. The university's commitment to interdisciplinary research has fostered collaborations between neuroscientists, molecular biologists, clinicians, and engineers, leading to innovative approaches to understanding and treating neurodegenerative diseases.
Research Excellence
Institute for Protein Research
The Institute for Protein Research is one of Japan's leading centers for studying protein structure, function, and dysfunction in disease. Key research areas include:
- Protein Aggregation Mechanisms: Investigation of how misfolded proteins like [amyloid-beta](/proteins/amyloid-beta), [tau](/proteins/tau), and [alpha-synuclein](/proteins/alpha-synuclein) aggregate into toxic oligomers and fibrils
- Structural Biology: Using cryo-EM and X-ray crystallography to determine the structures of disease-related proteins
- Therapeutic Development: High-throughput screening for compounds that can prevent or reverse protein aggregation
- Cellular Quality Control: Research on [autophagy](/entities/autophagy), [ubiquitin-proteasome system](/mechanisms/ubiquitin-proteasome-system), and molecular chaperones
Center for Advanced Mental Sciences
This interdisciplinary center focuses on the intersection of psychiatry, neurology, and neuroscience:
- Clinical Research: Large-scale studies on Alzheimer's disease biomarkers and progression
- Neuroimaging: Advanced MRI and PET imaging to visualize amyloid plaques, [tau](/proteins/tau) tangles, and neural network dysfunction
- Therapeutic Trials: Participation in international clinical trials for novel AD and PD therapeutics
- Sleep and Circadian Research: Understanding how sleep disruption contributes to neurodegeneration
Graduate School of Medicine
The Graduate School of Medicine houses multiple departments conducting cutting-edge neurodegenerative disease research:
- Neurology Department: Clinical care and research on AD, PD, ALS, and rare neurological disorders
- Molecular Neuroscience: Investigating the cellular and molecular mechanisms of neuronal death
- Regenerative Medicine: Stem cell therapies and tissue engineering approaches to neuronal replacement
- Neuroimmunology: Understanding how immune system dysfunction contributes to neurodegeneration
