Research Abstract

HTLVーIによる細胞癌化の分子機構の中で最も重要と考えられるp40^<tax>の転写活性化機構の解析が進展した。p40^<tax>分子とGAL4分子のDNA結合ドメインとを遺伝子上で融合させたところ、この融合分子にp40^<tax>の転写活性化能が証明された。すなわちp40^<tax>はDNA結合分子と直接接触することによって転写活性化を促進するという可能性が示唆された。他方、p40^<tax>の標的塩基配列に結合するCREB様分子が同定され、その中の少なくとも一分子がp40^<tax>と共沈したことからp40^<tax>と複合体を形成している可能性が示された。また細胞質ではp40^<tax>とHSP60の共沈もみられ、p40^<tax>とHSP60の複合体も存在した。HTLVーIのgagーpol間のORFがプロテア-ゼ遺伝子であることが証明され、この領域の転写がリボゾ-ムフレ-ムシフトによることが示された。HTLVーI免疫応答がHLAハプロタイプによって規定され、ATL患者は低応答性であることが明らかとなった。ウサギを用いてHTLVーIの母乳感染が抗HTLVーI陽性ヒト血清IgGの接種によって阻害されることが証明された。
