Recent Activities

I have been studying the various biological events at the cellular level in terms of the lipids that constitute membranes. Up to the present, I have been involved in the development of tools for the intracellular visualization of lipids, and have applied these techniques to approaches of genetics and cell biology in my research. In particular, my recent research has focused on sterols (cholesterol in humans, ergosterol in fungi, etc.). Although this molecule has been discovered 250 years ago and its importance has become clear, there are still many questions that remain unanswered. Recently, in addition to the transport proteins that exchange sterol molecules with the membrane, I have shown that the distribution of the phospholipids that make up the membrane is necessary for membrane homeostasis of sterol molecules. 
 
We phenotypically analyzed yeast genetic mutants of flippases and Sfk1, which are involved in phospholipid asymmetry at the plasma membrane. The results revealed that disruption of asymmetry impairs plasma membrane sterol retention, thereby causing abnormalities in various machineries involved in plasma membrane, and that phospholipid asymmetry is essential for plasma membrane sterol retention (Kishimoto, T., et al. (2021), Mol Biol Cell.).
 
The distribution of sterols was analyzed using the plasma membrane spreading process. The results revealed that the distribution of cholesterol between the bilayers of the plasma membrane changes the balance between the outer and inner layers during the formation of filopodia, thereby controlling the activity of Cdc42, a Small GTPase, to promote filopodia formation (Kishimoto, T., et al. (2020), FASEB J.).
 

Message to Students

Thanks to belonging to various laboratories, I have been able to interact with many researchers. I realize that such friendships will greatly develop my research. For this reason, I value the idea of a once-in-a-lifetime encounter. Feel free to get in touch if you need anything.
