Introduction

In our research projects, we develop a new drug delivery system which targets the brain, new imaging technology, and single cellular separation assay technology to elucidate the expression of brain functions in terms of morphology and cell structure, and to evaluate the mechanisms of expression of high-level brain functions such as memory and emotion, at the genetic, cellular, and organism levels. In addition, we are working on developing techniques with which we can artificially control such functions. Our aim is to apply this research to develop comprehensive therapies and diagnostic methods for brain disorders and to discover new drugs.
We have been working closely with industry, and, based on our experience, we are fully aware of the importance of basic research in medicine. It is true that basic medical research is the basis of modern medicine, however, at the same time, it is those who are involved in medical treatment who should decide the orientation of how to apply research results in the clinic. We would like to continue our research, with the aim of maintaining a balance between clinical and research aspects.

Research Projects

  1. Elucidation of the mechanism of microglia in the regulation of higher brain function
    (1) Brain-specific migration of microglia, and its application in brain-targeted drug delivery
    (2) Microglial toxic changes in neural disorders
    (3) Control of higher brain functions by microglia and their subtypes
  2. Development of “Tissue Penetrating Cell Technology” and “in vivo Imaging Methods”
    (1)Tissue penetrating cell analysis, drug targeting using these cells’ properties and application in disease treatment
    (2)Development of innovative bio-imaging methods
    - In vivo observation of gene expression using MRI for small animals
    - Bio-imaging using wide-spectrum near-infra red light sources - Bio-imaging of toxic transformation of microglia
    - Mass Spectrometry Imaging
    (3)Controlling cell activation using light
  3. Altered decision-making in neuropsychiatric disorders
    Decision-making is a key activity of everyday life. Consequently, disturbances in the ability to make appropriate decisions or anticipate their possible consequences can result in massive social, medical, and financial problems. Impaired decision-making is recognized as a core problem in the neuropsychiatric disorders, and a better understanding of the mechanisms underlying impaired decision-making should provide insights leading to successful treatments for these diseases. Recently, we have demonstrated that GABAergic interneurons in the insular cortex are involved in altered decision-making in animal model of addiction. GABA receptors might be targeted by novel treatments for impaired decision-making in patients with neuropsychiatric or addiction disorders. We would like to consider roots of risky decisions in further research.
