Regulatory science is defined as "science for adapting the achievements of technology to social and human needs in the most optimal way, by making precise prediction, evaluation, and judgment based on evidence." This field develops basic and clinical research as a regulatory science in medical care and aims to apply it to professionals including clinical laboratory technicians, clinical engineers, radiologists, and medical radiologists. In addition, graduate schools train drug development researchers, clinical research coordinators, genetic counselors, and embryo culture technicians by conducting research and education that takes advantage of the characteristics of each medical job.

Research Theme

・Elucidation of the pathophysiology of chromosomal structural abnormalities
・Genetic counseling for Emanuel syndrome

Transsopid crossovers, as assessed by FISH

Chromosome changes vary widely and may go unnoticed without symptoms, but they can be serious if they affect the function or excess or deficiency of genes. t(11;22)(q23;q11) chromosome translocation carriers have no symptoms, but when they have children, they may be born with an excess of chromosome 22 derivative. This is known as Emanuel syndrome. We are investigating the mechanism and pathogenesis of this chromosome change, as well as the support system for patients and their families. (Tamae Ohye)

・Elucidation of the pathology and etiology of psycho-neurological diseases
・Development of biomarkers and therapeutic agents based on pathophysiology

Behavioral tests to evaluate cognitive functions

We are conducting brain and nervous system research in the fields of molecular biology and neuropsychobehavioral pharmacology for psychiatric disorders, such as Alzheimer's disease, schizophrenia, drug dependence, bipolar disorder, ADHD, depression, and autism. We also carry out translational research to develop novel therapeutic agents, phytochemicals, and diagnostic biomarkers based on our findings. We conduct translational research. (Akihiro Mouri)

・Elucidation of the pathogenesis of neuropsychiatric disorders focused on neuron-glial network.
・Effects of abnormalities in peripheral–central connections on brain functions

In situ hybridization to investigate gene expression

The central nervous system is composed of not only neurons but also glial cells. Recently, it has been reported that not only abnormalities in neurons but also glial function are implicated in the development of neuropsychiatric disorders. We examine how abnormalities in glial cells influence on neuronal functions and development of neuropsychiatric disorders, using glial cell-specific genetic manipulation.
In recent years, it has been reported that abnormalities in the peripheral nervous system, such as the intestinal microbiota and peripheral immunity, also play a role in the development of neuropsychiatric disorders. By analyzing the composition of microbiota and peripheral immune cells, we study how abnormalities in the peripheral-central nervous system affect brain function. (Kazuo Kunisawa)

・Rehabilitation Effect Based on Alteration of Brain Molecules and Improvement of Paralysis in Rats with Cerebral Infarction.<br>・Development of Rehabilitation Training and Drug Combination Therapy for Rats with Cerebral Infarction

Rotarod test to evaluate the degree of paralysis after cerebral infarction

The purpose of this study is to identify the factors that determine the rehabilitation effect in a rat model of cerebral infarction through basic research. In this study, we compared the effects of spontaneous motor training using a running wheel cage on cerebral infarction model rats with and without motor training using the Nanakuri Forepaw stage (NAF stage), which we developed as an evaluation method for forelimb paralysis applicable to rats, and the rotarod test, which evaluates motor coordination and balance sensation in a combined manner. As a result, significant improvement in paralysis and motor function was observed. In addition, we are currently analyzing the changes in bioactive substances in the cerebral cortex and basal ganglia during the recovery process of paralysis. If the mechanisms and functional molecules involved in the recovery process of paralysis after stroke are clarified, it is expected that efficient and effective treatment methods for rehabilitation to improve paralysis will become clearer.

・Analysis of Environmental Effect of Radiations and Dosimetry<br>・Analysis of Radiation Risk Communication

Dose estimation by experimental

There are various natural and artificial radiation sources around us.
For example, radiation is effectively used for therapy and diagnosis in the medical field. It is important to analyze the behavior of radiation and dosimetry by experiment and calculation to ensure the safety of the facilities and to develop safety regulatory criteria.
In addition, there has been increasing interest in radiation risk communication among radiation experts. It is a big challenge for radiation experts and the public to learn and believe in each other. (Sumi Yokoyama)
