Outline of Final Research Achievements |
A high level of high-density lipoprotein (HDL) cholesterol in the blood is widely accepted as an anti-atherosclerotic marker; however, recent studies indicate that the HDL quality as expressed by oxidized HDL (oxHDL) can be more important atherosclerotic marker than the HDL-cholesterol levels. When we compared several oxHDL markers in healthy subjects and patients with atherosclerotic diseases, there found to be a similarity and difference in the results observed among the markers. This suggests a variation of in vivo oxHDL status and a need of proper application of oxHDL markers to the clinical setting.

Academic Significance and Societal Importance of the Research Achievements |
高比重リポ蛋白(high-density lipoprotein:HDL)コレステロールは抗動脈硬化指標として、酸化(ストレス)は動脈硬化指標として有名である。酸化変性修飾を受けたHDL、酸化HDLが測定できるようになり、酸化HDLの意味するところについての研究が求められている。酸化HDLの測定にはいくつかの方法があり、その異同を検証したところ、その測定結果は必ずしも同様の挙動をしないことが判明した。今回の結果は、生体内酸化HDLの多様さの認識、また病態解析や疾病管理に適用する際の酸化HDL種の考慮を促す点で意義深い。
