PBMCを密度遠心分離法(lymphoprep)により白血球除去材から単離し、凍結保存した。PBMCを蘇生させ、ゾレドロン酸(5μM)で刺激したPBMCをIL−2(1000IU/mL)と5%ヒトAB血清の存在下で、増殖培地において培養した。培養物において48時間後(37℃、5%CO2、加湿雰囲気)、細胞に、伝統的CAR配列(抗CD19scFv−CD28−CD137−CD3ζ)または共刺激性CAR配列(抗CD19scFv−CD28−CD137)のいずれかと、MOI10の5μg/mLのポリブレンと共に、レンチ−CMV−MCS−EF1a−puro構成物を含有するレンチウイルスを形質導入した。形質導入を24時間後に繰り返した。CARmRNA発現を、5日目に両構成物の発現を検出するユニバーサルプライマーを用いて、QPCRにより検証した。各構成物の特異的な発現を、差別的プライマーおよびユニバーサルプライマーの組み合わせを用いて確かめた(図5、6のように)。
細胞に伝統的CAR配列を含有するレンチウイルスを形質導入し、例1に記載したように増殖させた。形質導入後7日目に、形質導入したまたは形質導入していないγδT細胞を、CD19陽性標的細胞株、DaudiまたはRamosと共に共培養することにより細胞毒性活性を評価した。標的細胞株を、フローサイトメトリーを用いて、CD19標的集団の特異的視覚化のために、非毒性膜染料PKH67(5μM)で染色した。ガンマデルタT細胞または伝統的なCARを発現するγδT細胞と共に4.5時間共培養した後、共培養物をannexin Vおよびヨウ化プロピジウム(PI)で染色してアポトーシス細胞を可視化した。特異性細胞死率を標的細胞集団においてのみ計算した。非形質導入γδT細胞と比較し、CAR形質導入γδT細胞の効能はCD19陽性標的細胞において増大した(図7)。
細胞に伝統的CAR配列または共刺激性CAR配列を含有するレンチウイルスを形質導入し、実施例1に記載したように増殖させた。CD19陽性標的細胞株、DaudiまたはRamosを24時間、+/−5μMゾレドロン酸で前処理した。細胞毒性活性を実施例2に記載するように評価した。PKH67染色標的細胞(+/−ゾメタ前処理)を形質導入したまたは形質導入していないγδT細胞とともに共培養した。共刺激性CAR発現γδT細胞は、CD3ζ活性化ドメインを欠くにも関わらず、IPP感知によるγδTCRを介した活性化により代わりにシグナル1が提供され、CD19陽性標的細胞に対して伝統的CAR発現γδT細胞と同様の細胞毒性を呈した。両CARは、非形質導入γδT細胞と比較した場合、γδT細胞に対し細胞毒性の増大を提供した(図8)。
