| Outline of Final Research Achievements |
Adenosine 5’-triphosphate (ATP) is a metabolic molecule which is used for all subcellular processes as the major energy currency of cells. The intracellular ATP concentration was reported to affect the neuronal excitability in ex vivo conditions. However, it has been unclear the physiological dynamics of intracellular ATP levels in the living brain, which has energy homeostatic regulation mechanisms. Here we conducted in vivo optical recording of brain intracellular ATP dynamics using knock-in mice for fluorescent ATP probes ubiquitously expressed in the cellular cytoplasm and the fiberphotometric system. We observed the unique pattern of cortical intracellular ATP dynamics across sleep-wake cycle of mice.
