Research Abstract |
Post-infarct mortality was prevented in interleukin-17 knockout mice (IL17-KO) compared with wild-type mice. Left ventricular dysfunction, increase in LV weight to body weight ratio, and myocardial fibrosis 28 days after myocardial infarction were significantly attenuated in IL17-KO mice compared with wild-type mice. To investigate the mechanism for left ventricular remodeling inhibition in IL17-KO mice, we conducted microarray analysis. Microarray analysis revealed that the expressions of extracellular matrix related genes were lower in IL17-KO mice than those in wild-type mice. These results suggest that IL17 may play a pathogenic role in the development of left ventricular remodeling after myocardial infarction, possibly through the regulation of extracellular matrix genes expression.
