Description
(a)第1蛋白及び第2蛋白を分泌するか分泌するように変異された細胞に、又は、第1蛋白を分泌するか分泌するように変異された細胞及び第2蛋白を分泌するか分泌するように変異された細胞を組合せた細胞セットに、候補薬剤を接触させること、ここに、第1蛋白はCXXXボックスを含みかつプレニル化に依存して分泌される蛋白であり、第2蛋白はプレニル化に依存しないで分泌される蛋白である;
(b)前記細胞又は細胞セットから分泌される第1蛋白の有無又は量を測定すること;及び
(c)第2蛋白の分泌を阻害せずかつ第1蛋白の分泌量を減少させるか或は無くする候補薬剤を効力のあるプレニル化阻害剤として同定すること
を含むことを特徴とする(形態1・基本構成1)。
上記の方法において、前記第1蛋白は、大デルタ抗原であることが好ましい(形態2)。
上記の方法において、前記第2蛋白は、HBsAgであることが好ましい(形態3)。
上記の方法において、前記第1蛋白は、CXXXボックスを含みかつプレニル化に依存して分泌される分泌蛋白が、そのCXXXボックスの代わりに、CXXXボックスを含みかつプレニル化されても分泌されない非分泌蛋白のCXXXボックスを含むよう変異されたキメラであることが好ましい(形態4)。
更なる視点において、本発明は、ウイルスの形態形成、生成、放出或は脱外被を抑止する方法に関するもので、その方法は、少なくとも1つのウイルス蛋白のプレニル化或はポストプレニル化反応を効果的に妨げることから成る。他の視点において、本発明は、候補薬剤をプレニル化阻害能力で選別する検定法に関する。該方法は、(a)″CXXX″ボックスを含む第1の蛋白と第2のコントロール蛋白であって、前記第1の蛋白の分泌はプレニル化に依存し、第2のコントロール蛋白の分泌はプレニル化に依存しないものを分泌する細胞か、或は分泌するように変異された細胞を提供すること、ここで、第1の蛋白及び第2の蛋白をそれぞれ分泌する細胞は同一又は異なってもよく、(b)第2のコントロール蛋白が分泌される条件下で前記細胞を候補薬剤と接触させること、及び
(c)前記細胞から分泌される第1の蛋白の有無又は量を測定することを含み、分泌された第1の蛋白の量を減少させるか或は無くする候補薬剤が効力のある上記プレニル化阻害剤である。更に他の視点において、本発明は、ウイルス蛋白のプレニル化或はポストプレニル化反応を阻害するのに効果のある薬剤を投与することにより、ウイルス感染を治療する方法に関する。好ましい実施態様においては、ウイルス蛋白は、D型肝炎ウイルスの大(large)デルタ抗原、HBVの核抗原或はHIVのネフ(nef)蛋白である。
本発明はまた、あるプレニル化蛋白を分泌させるための、プレニル化の必要条件を利用することにより、プレニル化阻害剤としての候補薬剤を選別する方法を提供する。分泌のためにプレニル化が必要なそれらの蛋白に対して、直接かつ単純な方法で検定を実施することが出来る。その分泌がプレニル化に依存している第1の蛋白を分泌するか或は分泌するように変異させた細胞を、実験用細胞として用いる。分泌がプレニル化に依存しない第2の蛋白を、コントロールとして用いる。このコントロール蛋白は、第1蛋白と同一又は異なる宿主細胞により分泌させてもよい。候補薬剤を、両方の蛋白を分泌する細胞か、又は各々を分泌する細胞を組合せたセット(matched sets)に投与する。分泌は、第1及び第2の分泌蛋白の有無について細胞上澄み液を検定することにより、例えば通常のELISA検定法により容易に評価することが出来る。合格する候補薬剤は、コントロール蛋白の分泌を抑止することはないが、分泌のためにはプレニル化が必要なテスト試料では蛋白分泌を抑止する。
アミノ酸配列データバンクを調べて、C−末端に″CXXX″ボックスを含むウイルス蛋白を選別することによって、プレニル化を行うウイルス蛋白を更に得ることが出来る。そのような蛋白の実例リストとしては、例えば、前記のごとく、HAV、HCV、HSV、CMV、VZV、インフルエンザウイルス、タバコモザイクサテライトウイルス及びオオムギストライプモザイクウイルスなどの植物ウイルス、B型肝炎ウイルスの核抗原及びHIV−1のネフ(nef)遺伝子生成物などの特異蛋白がある。
