Research Topics

Human brain is the final frontier never explored by the experimental biologists. We are focusing on dendritic spines, which are fur smaller than the cell and have mysterious plasticity that underlie the brain function.

To explore human brain and to seek out the mechanism of mind, we are studying as follows:

  1. Molecular Mechanism of Synpase Formation
  2. Role of Cyntoskeleton in Synaptic Plasticity
  3. Pathogenesis of Higher Cognitive Function (Alzheimer's disease and Depression)
  4. Drebrin-imaging-based evaluation of mature synapses (Application to human iPSC-derived neurons)

1. Molecular Mechanism of Synpase Formation

Spikar is necessary for synpase formation

Spikar is a novel drebrin-binding protein. (Yamazaki et al., 2014). Spikar generallly  plays transcriptional co-activator in various cell nuclei, but in neurons spikar is also localized in cytoplasm and plays as a mediator in drebrin-dependent synapse formation.

4. Evaluation of Synapse Maturation (ex. human iPSC-derived Neurons)
