| Outline of Final Research Achievements |
Diabetes is known to delay the healing of wounds and cause complications such as foot ulcers. We have previously shown that the retention of neutrophils in diabetic cutaneous wounds is aberrant in mice, inflammation is prolonged, and the pathogenesis may be due to dysfunction of diabetes-derived neutrophils. MicroRNAs (miRNAs) are critical regulator for normal inflammatory response. Accordingly, in order to clarify the molecular mechanism of regulation of inflammation in diabetes-derived neutrophils, we identified specific miRNAs in these cells using microarrays and analyzed the function of miRNAs in diabetes-derived neutrophils. In this study, we identified specific miRNA in neutrophil of type 2 diabetes mouse using microarray, and clarified a part of functions of inflammation-related miRNA and its target genes using cellular and molecular biological.
