文献購入ページに移動高密度リポ蛋白質(HDL)は末梢組織の余分なコレステロールを運び出す働き,いわゆるコレステロール逆輸送をすることから抗動脈硬化性の血漿蛋白質であると考えられている.最近,このようなコレステロール代謝と直接関連しないHDL作用も注目されている.HDL中には強力な生理活性を発揮するスフィンゴシン-1-リン酸(S1P)が多量に含まれており,血管内皮細胞や血管平滑筋細胞におけるHDLの多彩な作用はS1Pによって仲介されていることが明らかにされてきた.したがって,血中S1P濃度変化は心血管機能調節の重要な要因と考えられる.本稿では,血中S1P,HDL中S1Pと心筋梗塞,虚血性心疾患などの冠動脈疾患との関連を調べた疫学コホート研究の現状についても紹介した.
