Research Contents
Three major projects are currently in progress.
  1. We are investigating how central nervous system responses to various stresses and adapt itself to a new environment at the level of neuron to living animal. Particularly we focus on the mechanism how neurotransmitters such as serotonin and neuropeptides act via receptors in so called limbic system including nucleus accumbens, hypothalamus and hippocampus.
  2. We also study the effect of sex hormones and neuropeptides on the structure and function of neural system to regulate the behavior. We use various methods for the neuroendocrinological approach such as molecular biology, cell biology, histochemical study, and behavioral assay.
  3. The third research project is a basic study for neurodegenenration. It involves the investigation of the mechanism of abnormal protein aggregation called Lewy bodies in neurons of patients with synucleinopathies such as Parkinson’s disease and dementia with Lewy bodies. α-Synuclein is a major constituent of Lewy bodies and recently evidence is accumulating that abnormally polymerized α-synuclein spread in the brain like prion protein by cell to cell propagation along the progression of diseases. We would like to unveil the mechanism of pathological α-synuclein spreading.
