Title: 血清由来ｃ型肝炎ウイルスを増殖させるためのヒト脂肪由来幹細胞の使用およびその用途
IPC: C12Q1/04
Filed: 2015-01-07
Abstract: 肝外部位におけるＣ型肝炎ウイルス複製は示唆されてきたが、しかし、完全なウイルス複製は肝細胞においてのみ確認されていた。ここで本発明者らは、ＨＣＶ感染個体から新たに単離されたヒト脂肪生成ＤＬＫ−１＋幹細胞（ｈＡＤＳＣ）が生体内でウイルス転写物、複製中間体およびウイルス抗原を含有し、ウイルス転写物が長期の生体外培養に際して上清中で増加したことを示すものである。さらに、ＨＣＶ（−）個体から単離されたナイーブｈＡＤＳＣは、臨床分離物の試験管内での完全な複製を支援し、感染は、細胞に関してはドナー非特異的であり、ウイルスに関しては遺伝子型交差性である。ウイルス感染／複製は、ＣＤ８１、ＬＤＬ−Ｒ、ＳＲ−Ｂ１、ＥＧＦＲ、アポリポタンパク質Ｅ、オクルディン、クローディン−１、ＮＰＣ１Ｌ１およびジアシルグリセロールアセチルトランスフェラーゼ−１によって媒介され、抗ウイルス薬によって阻害され得る。さらに、ｈＡＤＳＣ増殖ウイルス粒子の物理的特性はＪＦＨ１／ＨＣＶｃｃよりもむしろ臨床分離物に類似しており、試験管内感染したｈＡＤＳＣによって増殖したウイルスは、ヒト初代肝細胞に対して感染性である。したがって、ｈＡＤＳＣは、生体内ＨＣＶ保有宿主であり、臨床的なウイルス−宿主相互作用の新規な場所を意味する。ｈＡＤＳＣを生理学的に妥当な初代細胞培養システムとして利用して臨床分離物を増殖させることもできる。
