| Research Abstract |
Detailed immunohistochemical localization of water channel, aquaporins, in the brain was examined to understand water transfer in the brain tissue. In addition to the previous studies which described that aquaporin-4 was restricted to the perivascular cell membrane of astrocytes, I revealed that aquaporin-4 was widely distributed on the plasma membrane of astrocytes. This result suggests that aquaporin-4 plays very important role in water handling in the brain. In addition, distribution of aquaporins was examined in the mouse tissue. I found that aquaporin-5 is more widely distributed in the mouse respiratory epithelium than that in the rat. Aquaporin-5 in the mouse respiratory epithelium seems to play an important role in maintaining the respiratory function.
