Outline of Final Research Achievements |
We had tested the roles of an inducible prostaglandin E synthase, mPGES-1 in facilitation of inflammation-induced lymphangiogenesis (IL) elicited by lipopollysccharide (LPS). With LPS i.p. injections, lymphatics in diaphragm were widened and Lyve-1-positive ladder-structured lymphatics were increased temporally in comparison with vehicle-treated wild type mice (WT). This increase of lymphangiogenesis was accompanied with increased expressions of vascular endothelial growth factor (VEGF)-C/D. In mPGES-1 knockout mice (KO), IL was suppressed with reduced expressions of VEGF-C/D. When FITC-dextran was injected into peritoneal cavities, the residual amount of FITC-dextran was reduced significantly in WT with LPS treatment. This reduction was significantly restored in mPGES-1 KO. These results suggested that mPGES-1 had significant roles in facilitation of lymphangiogenesis active in fluid drainage during IL, and that this enzyme will be a novel target for controlling IL.
