| Outline of Final Research Achievements |
We found that Mincle and NLRs are critical in the process of natural immune response (IL-1a, IL-6 production) in the inflamed retina. During the regional inflammation, internal stem cells which modified muller glia cells were generated and activated. We purified these cells and analyzed specific proteins, and found DRP-2 and DRP-3 proteins (long isoforme) were elevated. Adding these factors into the cultured murine muller cells, they increased the proliferation ability and showed partial increase of nestin. We concluded these factors are critical for " inflammation" indued internal stem cells.
