Outline of Annual Research Achievements

本研究の目的は、エイズ関連悪性リンパ腫発症のマウスモデルを用いて、その発症機序の解明と予防法・治療法の開発に供することである。エイズリンパ腫の一病型である原発性滲出性悪性リンパ腫(Primary effusion lymphoma;PEL)のマウスモデルを用いて、以下の知見を得た。
1.PEL生存におけるIL-6とVEGFの役割:PEL細胞が、IL-6受容体とVEGF受容体を発現しており、またIL-6とVEGFを産生することが判明した。抗IL-6受容体抗体及び抗VEGF抗体は、in vitroではPEL細胞の増殖を阻害しなかったが、PELマウスモデルでは、腫瘍性腹水の産生を強く阻害した。IL-6とVEGFを介したシグナルは、PELの増殖には関与しないが、腫瘍性腹水の産生に強く関与している事が判明した。
2. PEL生存におけるSIRPα-CD47シグナルの重要性の検討:マクロファージは、SIRPαにより標的細胞のCD47を認識し、"Don't eat me" シグナルにより貪食を抑える。PEL細胞ではCD47が高発現していることを確認したため、PEL細胞とマクロファージの共培養系に抗CD47抗体を添加したところ、マクロファージによる貪食の増加を確認した。また、PELマウスモデルに抗CD47抗体を100μg/マウス週3回腹腔内投与したところ、腫瘍性腹水の大幅な減少が認められた。これらの結果から、PELに対するSIRPα-CD47シグナル阻害療法の有効性が期待できる。
3.PELに対するmethy-β-cyclodextrinの有効性:methy-β-cyclodextrinがPEL細胞膜上の脂質ラフトからコレステロールを引き抜くことで、PELにアポトーシスを誘導することを示した。
