Welcome to
The Section of Neuropathology (Lab number 1st/2nd)!,
Department of Neurology,
Kyoto University Hospital and Graduate School of Medicine!

Kyoto_u_NeurologyOur lab was first established in 1983 under the appointment of Prof. Masakuni KAMEYAMA who specialized in neuropathology of cerebrovascular disorder. Since the opening, we consistently continue our research on cerebrovascular, neurodegenerative and neuroinflammatory diseases, to improve our understanding of how disease starts and progresses and to help develop new treatments.

Kyoto_u_NeurologyNeuropathological research is mainly grouped into two methodologies; human neuropathology investigating autopsied brain and experimental neuropathology examining disease-model animal. Recently, we also apply rapidly evolving in vivo imaging techniques such as MRI and PET to visualize pathological process in the living brain. With these methodologies, the aim is to elucidate morphological changes directly connected to the disease and to lead to cures. We explore neuropathological tradition to the full and innovate new vision and technique in order for the success of the projects below.

Kyoto_u_NeurologyHuman neuropathology investigating autopsied brain: Our lab holds an extensive archive of tissue samples donated by individuals with neurological disease. The donated samples from the brain (376 in total) and other organs of the body were collected during post mortem examination at our Neurology department and affiliated hospitals. Under closely controlled conditions, tissue is stored as formalin fixed, paraffin embedded blocks and is frozen. The archive could not provide support for medical research, were it not for the generosity of patients and families who are able to donate tissue samples and organs despite their personal loss and grief.
Neurology, Kyoto-u
Kyoto_u_NeurologyUtilizing the donated samples, we are investigating the biological process underlying amyotrophic lateral sclerosis (ALS), Parkinson disease and movement disorders, vascular dementia and Alzheimer disease. The tissue samples are essential to validate the hypotheses and observations generated by the cell biology and biochemical studies of disease-model animals.
Experimental neuropathology examining disease-model animal:

Kyoto_u_NeurologyOngoing research on neurodegenerative disorders aims at identifying essential pathological mechanisms in ALS and Parkinson disease. To achieve the aim, we employ multidisciplinary approach involving molecular genetics, neurochemical and neurophysiological analyses. In addition to the Molecular Neuroscience Section (Lab number 4) of our Neurology department, we collaborate with a number of research institutions that are listed below:

1) Department of Epidemiology, Division of Radiation Bio-Medical Informatics, Research Institute for Radiation Biology and Medicine, Hiroshima University, Professor Hideshi Kawakami

2) Center for iPS Cell Research and Application, Kyoto University, Associate Professor Haruhisa Inoue

3) Center for iPS Cell Research and Application, Kyoto University, Professor Jun Takahashi

4) Unit for Neurobiology and Therapeutics, Molecular Neuroscience Research Center, Shiga University of Medical Science, Associate Professor Makoto Urushitani

5) Department of Neurology, Tokushima University Graduate School of Medicine, Professor Ryuji Kaji

6) Department of Neurology, Tohoku University School of Medicine, Professor Masashi Aoki

7) Montefiore Medical Center, Albert Einstein College of Medicine, Professor Asao Hirano

Kyoto_u_NeurologyIn the last five years, studies have identified multiple mechanisms by which gene mutations related to ALS cause the disease. These discoveries open a new field for ALS research. Analysis of the genes' protein products and their role in cell death may provide a clue to develop new treatments and find a cure for the disease.
In vivo imaging research:

Kyoto_u_NeurologyOur research aims at increasing our understanding of the mechanisms and causes leading to brain degeneration and dysfunction in Parkinson disease, Dementia with Lewy body, vascular dementia and Alzheimer disease. Our mission is to transform clinical problems into testable research hypotheses and to translate research findings into medical advances using state-of-the-art in vivo imaging techniques.

Kyoto_u_NeurologyRecent advances in in vivo imaging techniques allowed the use of these methodologies to visualize pathological findings in the living individual, which were previously identified only after death by an autopsied tissue sample. For example, a PET technique with Pittsburgh compound B (PIB) now enables us to visualize deposits of beta-amyloid, one pathological hallmark of Alzheimer's disease, in the living brain, which were previously identified only in an autopsied brain or a tissue sample of disease-model animal. The discovery of PIB PET technique not only expands our knowledge about Alzheimer disease but also opens the new possibility of pre-symptomatic intervention. We believe that development of tau and alpha-synuclein in vivo imaging agents makes a dramatic progress to improve our understanding of how neurodegenerative disorders start and progress.
Research on neuroinflammatory diseases:

Kyoto_u_NeurologyThe aims of our research are to clarify biological process underlying multiple sclerosis and neuromyelitis optica (NMO). We collaborate with number of research institutions including Kyoto Prefectural University of Medicine, National Hospital Organization Utano Hospital, Koseikai Takeda Hospital and Nagasaki University.
