| Outline of Final Research Achievements |
To elucidate roles 'Alarmins', which released from the injured tissue to alert danger to the neighbor healthy tissue, for the pathophysiological process of atopic retinal detachment, we investigated mouse retinal detachment models made by perforating retinal injury. We found positive immunolocalization of interleukin-33 (IL-33), a prototype of the alarmin, in the nuclei of the Muller glial cells of the healthy mouse retina. Upon perforating retinal injury, IL-33 released from the nuclei to the vitreo-retinal interface, and upregulate profibrotic genes in the injured retina. The results suggested that IL-33 may be a good therapeutic target or atopic retinal detachment in future.
