本発明は、微生物由来のイオン輸送型受容体ロドプシンのアミノ酸配列と動物由来のGタンパク質共役型受容体ロドプシンのアミノ酸配列とを有するキメラタンパク質の配列が挿入されたアデノ随伴ウイルス(AAV)ベクター又はレンチウイルスベクターを包含する。
実験には、野生型マウス(C57BL/6J,日本クレア株式会社)と網膜色素変性症モデル(rd1)マウス(C3H/HeJ Jcls,日本クレア株式会社)を用い、ともに3週齢オスのものを使用した。
グロエオバクター・ビオラセウスのロドプシン(Gloeobacter violaceus Rhodopsin(GR)、配列番号8)の細胞質側の第2ループに相当するN末端より137−145番目のアミノ酸に相当する配列を、ウシロドプシン(BvRh)(配列番号9)の137−145番目のアミノ酸相当配列に置換し、また、グロエオバクター・ビオラセウスのロドプシンの細胞質側の第3ループに相当するN末端より198−206番目のアミノ酸に相当する配列を、ウシロドプシンの225−252番目のアミノ酸相当配列に置換し、さらにグロエオバクター・ビオラセウスのロドプシンの132番目のアミノ酸であるグルタミン酸をグルタミンに置換したキメラタンパク質をコードするDNAをpCDNA3.1ベクターに挿入した。変異体の作製はクイックチェンジ法により行った。
AAV2シャトルプラスミドに、EGFP、又はGR/BvRh遺伝子をサブクローニングし、ウイルス発現コンストラクトとして、AAV2−CAGGS−EGFP−WPRE−pA(EGFPの発現用のベクター)、及び、AAV2−CAGGS−GR/BvRh−WPRE−pA(キメラタンパク質発現用のベクター)を作製した。ウイルスベクターのパッケージングはHEK293細胞にベクタープラスミド、AAVベクタープラスミド、アデノウイルスヘルパープラスミドの3種類のプラスミドをトランスフェクションすることにより行い、ウイルスベクターの精製には塩化セシウム法を用いた。なお、ベクター中、「ITR」は、「Inverted Terminal Repeat」の略である。「CAGGS」は、CAGプロモーターの領域の配列である。「WPRE」は、「woodchuck hepatitis virus post−transcriptional regulatory element」の略である。「pA」は、ペプチド・タグを意味する。「EGFP」は、「enhanced green fluorescent protein」の略である。
野生型マウス又は網膜色素変性症モデル(rd1)マウスに対し、塩酸メデトミジン(0.75mg/kg)、ミダゾラム(4mg/kg)、酒石酸ブトルファノール(5mg/kg)の混合液を腹腔内投与し、全身麻酔下にて、32ゲージ針を装着したマイクロシリンジを用いて鋸状縁付近から硝子体内に上述のAAVベクター(「AAV2−CAGGS−EGFP−WPRE−pA」又は「AAV2−CAGGS−GR/BvRh−WPRE−pA」)をそれぞれ1×1012vg/ml 1μl注射施行した。
AAV2−CAGGS−EGFP−WPRE−pAを注射した野生型マウスに注射してから7週後に網膜を摘出し、4%パラホルムアルデヒドで1時間固定し、whole mountした網膜を蛍光顕微鏡で観察した。その結果を図1に示す。図1中、GCL:神経節細胞層、INL:内顆粒層、ONL:外顆粒層を意味する。観察の結果、緑の蛍光(例えば、図1の矢印)が網膜中に見られたことから、ベクターの導入、目的遺伝子の発現は正常に行われることが確認できた。
AAV2−CAGGS−GR/BvRh−WPRE−pAを網膜色素変性症モデル(rd1)マウスに注射してから7週後に全身麻酔下で眼球を摘出し、その後95%O2及び5%CO2でバブリングしたAmes medium (Sigma−Aldrich,St Louis, MO; A1420)内に静置して網膜を摘出した。網膜について神経節細胞層が下向きに電極に接触するようにマウントし、光刺激を行い(白色光、1000cd/m2、1秒間)網膜神経節細胞の細胞外電位記録を行った。また、AAV2−CAGGS−GR/BvRh−WPRE−pAを注射していない網膜色素変性症モデル(rd1)マウスをコントロールとして、同様の方法で網膜神経節細胞の細胞外電位記録を行った。多電極アレイ測定には、MEA2100−Lite system(Multi−Channel Systems, Reutlingen, Germany)を用いた。その結果を図2に示す。図2中、(a)がコントロールのマウスについてのグラフを示し、図2中、(b)がAAV2−CAGGS−GR/BvRh−WPRE−pAを注射したマウスについてのグラフを示す。なお、図2のグラフ中、横軸は経過時間を示し、矢印で示した領域が光刺激を行った領域を示す。
