<材料および方法>
(細胞およびウイルス)
MK2(サル)細胞を5%のウシ血清アルブミン(BSA)を含有するDMEM中で、37℃にて70%の成長濃度(コンフルエンス)となるまで成長させた。
使用した主要な脂質はポリオキシエチレンセチルエーテル(PCE)であり、単独、あるいは、指示モル比でパルミチン酸(PA)またはヘキサデシルトリメチルアンモニウムブロミド(HTAB)と組み合わせて使用した。
nPLV調製物をPBSで指示濃度に希釈した。次に、希釈したnPLVをウイルスと混合して、最終容積が100μlになるようにした。このウイルス−nPLV混合物を室温で30分間にわたって振とうしながらインキュベートした。ウイルス濃度は105〜2×106粒子であった。
rSeV−Luc感染の場合には、細胞を溶血させ、プロメガ ルシフェラーゼ アッセイ システム(Promega Luciferase Assay System)を使用してルシフェラーゼ活性を測定した。測定はTD−20/20照度計(Turner Designs社製)を使用して行った。

(細胞およびウイルス)
MK2(サル)細胞を5%のウシ血清アルブミン(BSA)を含有するDMEM中で、37℃にて70%の成長濃度(コンフルエンス)となるまで成長させた。
nPLV調製物は、実施例1と同様に調製された。
nPLV調製物はPBSで指示濃度に希釈した。次に、希釈したnPLVを、単独で(シクロデキストリン無)、または0.5mM(最終濃度)のシクロデキストリンと組み合わせてウイルスと混合した(100μl)。このウイルス−nPLV混合物を室温で20分間にわたって振とうしながらインキュベートした。約105個のウイルス粒子を使用した。
MK2細胞を溶血させ、プロメガ ルシフェラーゼ アッセイ システムを使用してルシフェラーゼ活性を測定した。測定はTD−20/20照度計(Turner Designs社製)を使用して行った。
<結果>
エンベロープの脂質修飾によってエンベロープウイルス(EV)を不活化させる可能性を検討するために、本願出願人はセンダイウイルス(SeV)をモデルとして使用した。SeVはパラミクソウイルス科のエンベロープウイルスであり、いくつかのヒト病原性ウイルスと遺伝的および構造的類似性を有する。SeVはマウスを宿主とする呼吸器ウイルスだが、容易に高力価ウイルスストックを得ることができる孵化鶏卵等の様々な真核生物細胞中で成長させることができる。多くのEVと同様に、SeVは感染性に関してコレステロール依存性を有することが明らかになっているが、正確なメカニズムは完全には解明されていない。本願出願人は、ゲノムに異なる標識遺伝子をコードした2種類の組換型SeV(rSeV)を使用した。ルシフェラーゼ遺伝子をコードするrSeV−Lucでは、非常に感受性の高い生化学分析を使用して感染レべルを監視することができる。一方、rSeV−GFPは緑色蛍光蛋白質遺伝子をコードし、FACS(Fluorescence−Associated Cell Sorting)を使用して細胞レベルで感染を調べることができ、感染細胞の数を正確に測定することができる。
