“Elucidation of the mechanism underlying neuronal cell death and development for therapeutic drugs” is the theme of our research laboratory. Apoptosis is involved in neuronal cell death, and it has been suggested that caspases and endoplasmic reticulum (ER) stress participate as the underlying mechanisms. By using the molecular biological and pharmacological approaches, we are studying to clarify the molecular mechanisms and determinants for “point of no return” in neuronal cell death, and conducting basic research for elucidating the pathological mechanisms and the development for therapeutic drugs in central nervous diseases (stroke, schizophrenia, and manic disorder) and ocular diseases (glaucoma and diabetic retinopathy). We also have a variety of established animal models, and are analyzing biofunctional molecules related to pathological process and their mechanism using clinical samples and genetically modified animals. Furthermore, we are conducting researches on dietary supplements and traditional medicines.
