The Jikei University School of Medicine, Institute of Clinical Medicine and Research, WATABE Lab.

About Us

Watabe lab was newly established in April 2017. We are interested in the molecular and cellular mechanisms underlying adaptive behaviors which are modulated by emotional and motivational states.
Currently, we are recruiting Ph.D. students! If you are interested in our research and the lab, please feel free to contact us.

The paper on the joint research with Dr. Kim and Dr. Ohtsuka in Yamanashi University is now published in Cell Chemical Biology! Congratulations!
“A light-controlled phospholipase C for imaging of lipid dynamics and controlling neural plasticity”
In this study, with support from AMED, we developed a light-controlled phospholipase C (opto-PLCβ). The newly developed technology is expected to be useful for elucidating the mechanism of memory formation and developing treatments for neurological diseases.

“All-optical presynaptic plasticity induction by photoactivated adenylyl cyclase targeted to axon terminals”
In this study, with support from AMED, we developed a presynaptically localized photoactivated adenylyl cyclase (bPAC).Furthermore, in combination with other optotools, we succeeded in developing an all-optical technology to manipulate intracellular signaling systems and synaptic activity. The newly developed technology is expected to be useful for elucidating the relationship between synaptic regulation and brain function and for establishing treatments for neuropsychiatric disorders.
