Preemptive medicine is a novel model of personalized medicine in which the factor of a disease is predicted at an earlier stage and regulated by therapeutic interventions. To develop preemptive medicine for neuropsychiatric diseases, our department aims at discovering the molecular targets for neuropsychiatric diseases, such as stress-induced depression and tau lesion-induced Alzheimer's disease, using animal models and clinical research in order to develop diagnostic and therapeutic agents.

Objective diagnosis and assessment of psychiatric disorders are difficult because they are based on interviews and questionnaires. Our goal is to establish new biomarkers for psychiatric disorders from blood and other sources that can be used to assess the onset and severity of symptoms, and the efficacy of medications.

The pathogenesis and etiology of neuropsychiatric disorders are complicated and diverse. We aim to overcome neuropsychiatric disorders by integrating clinical research analyzing the biomarkers of diseases with basic research using animal models and cell culture.

Our goal is to develop novel therapeutic agents, phytochemicals, and diagnostic biomarkers. This will be achieved by analyzing pathological and pathogenic mechanisms of psychiatric disorders in mouse models that we develop based on epidemiological and genetic findings in patients.

In collaboration with the Resource Center for Health Science (RECHS), we aim to develop a diagnostic agent for neuropsychiatric disorders and to perform preemptive medicine by detecting changes before onset through analyzing annual serum samples and questionnaire data.

Kynurenine and other metabolites in the tryptophan metabolic pathway are related to the pathogenesis of neuropsychiatric disorders by acting as agonists or antagonists of neurotransmitter receptors. Our goal is to develop novel therapeutic agents by screening chemical compound libraries to find inhibitors of enzymes in tryptophan metabolism.

To elucidate the pathogenesis of neuropsychiatric disorders, we are analyzing 1) peripheral-central interactions through the composition of the intestinal microflora and function of peripheral immune cells, and 2) glial-neural interactions through glial cell-specific genetic interventions.
