Research Abstract

本研究は以下の3つの項目に大別される。(1)HTLV-I遺伝子産物の構想機能に関する研究、(2)HTLV-Iキャリア、ATL患者の臨床疫学および免疫学的研究、(3)動物感染実験系を用いた研究。(1)に関してはHTLV-I・pX産物であるp40^<tax>の新たな標的遺伝子としてc-fosが同定され、またp40^<tax>が作用するLTR上のエンハンサー配列の詳細な解析もならさた。さらにgag-pol間に存在するプロテアーゼ遺伝子の同定と翻訳機構が明らかにされた。他方、p40^<tax>の機能発現を解析する上で必要なp40^<tax>に対する単クロン抗体も作製された。(2)に関しては、HTLV-I感染からATL発症に到る過程には5つの異なった要因が想定されること、また健常HTLV-Iキャリアの中に相当数のpre ATLが存在することが明らかにされた。さらに、ATL家系に特徴的なHLAハプロタイプとHTLV-I異的T細胞免疫低応答性とが相関することも示唆された。(3)に関しては、先ずウサギにおいてHTLV-Iに対する抗血清投与によってHTLV-I感染が防御されることが明らかにされ、HTLV-Ienv組換えワクシニアウイルスあるいは組換えenv蛋白によるワクチンの効果に関してはウサギならびにサル感染系でも確かな結果を得るには至っていない。ラットではHTLV-Iキャリア母乳による母仔間感染が証明されたが、その伝播効率は低く、ラットは動物感染モデル実験系としては難点が多いことも分かった。
