| Outline of Final Research Achievements |
Atherosclerosis is a fundamental condition for cardiovascular diseases. It is well recognized that atherosclerotic events are initiated by damage in inner side of vascular walls. We found that in addition to inner side, event in adventitial side, especially abnormality in the formation of microvasculature closely contribute to progression of atherosclerotic plaque. We also found that abnormality of microvascular formation is due to an interaction of PCs and EC tubes and perivascular wiring of peripheral nerve.

| Academic Significance and Societal Importance of the Research Achievements |
動脈硬化の病態の場所が、従来から注目されている内膜だけでなく、外膜部（特に微小血管形成異常）にもある、さらに、この微小血管形成異常の機序を明らかにすることにより、従来の動脈硬化治療で克服できなかった「高齢化社会下での動脈硬化」治療戦略の一つの方向性を示せた。また、新生血管の成熟化と平行して、神経線維の伴走化する知見を得たことにより、微小血管形成制御だけでなく、神経再生の機序解明に繋がる糸口となった。
