| Outline of Final Research Achievements |
The kidney plays an essential role in the maintenance of physiological homeostasis of fluid and electrolytes in the body. Adenosine is a well known regulator of renal function and blood flow; however, the normal distribution of adenosine in the kidney has not been well elucidated. Matrix-assisted laser desorption/ionization (MALDI) - imaging mass spectrometry (IMS) is a novel technology for visualizing the distributions of molecules in situ. Small metabolites in the kidney has not been examined by the method thus far. In the present study, we identified a remarkable accumulation of adenosine in outer stripes of outer medulla (OSOM). The local accumulation of adenosine in OSOM may play a significant role for the physiological functions of adenosine such as the regulation of interstitial blood flow in the kidney.
