Outline of Annual Research Achievements

抗リン脂質抗体症候群(APS)は病原性自己抗体である抗リン脂質抗体(aPL)による血栓症や妊娠合併症をきたす疾患だが動物モデルが乏しく、とりわけ血栓症を自然発症する動物モデルは皆無であり、またモノクロナル抗体による流産の発症も明らかではなかった。
今回、動脈硬化モデルを用いaPLを追加投与することにより血栓症の誘発を試みたが、認めなかった。一方、APSで特徴的な補体活性化が病態発症に関与することが近年明らかになり、そしてその原因が補体第1成分(C1q)に対する自己抗体(aC1q)であることを我々は発見し、aC1qモノクロナル抗体をマウスに投与することによって高率に流産をきたし、抗補体治療によってそれが回避されることを発見し投稿準備中である。一方、aC1q投与マウス及びaPL+aC1q共投与マウスでも、血栓症発症は認めなかった。APS患者では、1次的な血管内皮細胞異常も示唆されており、そのうちeNOS異常に我々は注目し、eNOS KOマウスをはじめとした内皮細胞異常を有するマウスと抗リン脂質抗体およびaC1qを用いたモデルの作成を検討中である。
