| Outline of Final Research Achievements |
Previous reports have revealed that high aqueous MCP-1 level is related to poor surgical outcome of glaucoma filtration surgery. Therefore, we focused on the effect of MCP-1 on wound healing processes in glaucoma filtration bleb (bleb). Firstly, we applied MCP-1 on the bleb for a long period and investigated its effects on scar formation using rabbit models. As a result, the accumulation of inflammatory cells were observed. Second, we conducted in vitro experiments in that human conjunctival fibroblasts (HConF) and macrophages were co-cultured, and found that significant upregulation of α-SMA in HConF. Taken together, it was indicated that aqueous MCP-1 escape into the bleb after surgery for a long period and causes monocyte-macrophage recruitment, resulting in promoting wound healing reaction in the bleb. The results of current study were one of the important results in elucidating the mechanism of aqueous MCP - 1 on wound healing of the bleb after glaucoma filtration surgery.
