Molecular and Cellular Physiology Lab
Machine-translated · View original
A physiology lab that explores how taste and throat sensations help maintain the body's functions.

AboutAbout the lab
Uncovering how the body senses changes inside and outside itself
The Molecular and Cellular Physiology Lab studies how the human body senses changes in its internal and external environment and keeps its own state constant.
Much about the senses remains unexplained, and sensory cells that have not yet been discovered are thought to exist.
Using mammals as subjects, the lab aims to clarify the principles of new senses and apply them to medicine and physiology.
The lab was newly established in January 2026 as a lab of the Graduate School of Medicine, Kyoto University.
Key terms
- Taste bud
- A cluster of taste-sensing cells found on the tongue and elsewhere. It acts as a sensor that distinguishes the chemicals in food.
- Channel synapse
- A mechanism that sends signals to nerves by releasing a neurotransmitter through ion channels in the cell membrane. The term was coined by this lab.
- Homeostasis
- The tendency to keep body temperature, blood pressure, and other conditions constant even when the environment outside or inside the body changes.

ResearchResearch themes
Behaviors such as eating, drinking, and swallowing are finely regulated in response to changes inside and outside the body, but much remains unknown about the sensory mechanisms underlying them. The lab aims to clarify the network of senses that supports homeostasis.
*Illustrative imageHow Taste Is Sensed, from Cells to the Brain
The lab investigates how the taste buds on the tongue detect chemicals, using measurement and manipulation of taste cell activity, single-cell analysis, and behavioral analysis.
*Illustrative imageExploring the Function of Channel Synapses Broadly and in Depth
Taste cells release the neurotransmitter ATP through ion channels rather than synaptic vesicles. The lab investigates how these "channel synapses" work and how they are formed.
