도 3A는 CD39 단백질의 표면 상에서 돌연변이체 5 (M5), 15 (M15) 및 19 (M19)의 돌연변이된 잔기의 위치를 도시한다. 도 3B는 상이한 항체에 대한 돌연변이체 5, 15 및 19의 결합 결과를 도시한다.
도 4는 유세포측정법으로 평가된, 인간 CD39를 발현하는 세포에 대한 항체 I-394의 결합을 도시한다. I-394는 인간 CD39 를 발현하는 세포(CHO-huCD39), 사이노몰거스 CD39 를 발현하는 세포(CHO-cyCD39) 및 Ramos 림프종 세포에 결합하지만, 쥐과 CD39 를 발현하는 세포(CHO-moCD39)에는 결합하지 않는다.
도 5는 존재하는 ATP의 양에 비례하는 발광 유닛을 정량하여 평가시에, 항체 I-394가 종양 (Ramos) 세포, 인간 CD39 를 발현하는 세포(CHO-huCD39), 및 사이노몰거스 CD39 를 발현하는 세포(CHO-cyCD39)에서 CD39 효소 활성을 차단하는데 매우 강력하다는 것을 도시한다.
도 6은 존재하는 ATP의 양에 비례하는 발광 유닛을 정량하여 평가시에 항체 I-394가 가용성 재조합 인간 CD39 단백질의 효소 활성을 차단하는데 매우 강력하다는 것을 도시한다.
도 7은 ELISA 어세이로 평가시에 항체 I-394가 인간 CD39에는 결합하지만 임의의 인간 이소폼 CD39-L1, CD39-L2, CD39-L3 또는 CD39-L4에는 결합하지 않는다는 것을 도시한다.
도 8은 CD4 T 세포 활성화에 대한 ATP-매개된 DC 활성화의 효과를 평가하기 위한 실험 절차를 도시한 것으로서, ATP-활성화된 DC를 세척하였고 그 다음으로 5일 동안 혼합 림프구 반응 (MLR)을 위해 동종이계 CD4 T 세포 (1 MoDC / 4 T 세포의 비율)와 인큐베이션시켰다. T 세포 활성화 및 증식은 유세포측정에 의해 CD25 발현 및 Cell Trace Violet 희석을 통해 분석하였다.
도 9는 moDC 상에서 HLA-DR 발현을 도시하고 도 10은 moDC 상에서 CD83 발현을 도시한다. 이들 도면은 항-CD39 차단 항체 I-394 및 CD39의 화학적 억제제가 각각 0.125 mM, 0.25 mM 또는 0.5 mM에서 moDC 활성화를 야기시킨다는 것을 도시한다. 그러나, 항-CD39 항체 BY40 또는 항-CD73 항체는 수지상 세포 (DC)의 ATP-유도된 활성화를 촉진할 수 없어서, 항체가 ATP 이화작용을 충분히 피하도록 효소 활성을 차단할 수 없다는 것을 시사한다. 범례는 위에서 아래로 그래프의 좌측에서 우측의 막대에 상응한다.
도 11은 CD25 발현은 MLR 어세이에서 ATP의 존재 하에서 활성화된 MoDC가 T 세포 활성화 및 증식을 유도할 수 있었고, 항-CD39 차단 항체 I-394에 의한 ATP-매개된 MoDC 활성화의 증강은 그 결과로 더 높은 T 세포 증식 및 활성화를 야기시켰다는 것을 확인한 것을 도시한다. 위에서 아래로 범례는 좌측에서 우측으로 그래프의 막대에 상응한다.
도 12A는 0.01 ㎍/mL, 0.1 ㎍/mL 및 1 ㎍/mL로 항-sCD39 항체의 3가지 상이한 용량에서, 첨가된 ATP의 존재 하에, CD4 T 세포 증식에 대한 항-CD73 항체의 용량 범위를 도시한다. 가용성 인간 CD39를 중화시킬 수 있는 항-CD39 항체는 CD4 T 세포 증식의 복원에서 항-CD73 항체의 강력한 강화작용을 보여준다. 도 12B는 첨가된 ATP의 존재 하에서 CD8 T 세포 증식에 대한 항-CD73 항체의 용량 범위를 도시하며, 항-sCD39 항체는 CD8 T 세포 증식의 복원에서 항-CD73 항체의 강력한 강화작용을 보여준다.
도 13A, 13B 및 13C는 질환 병기 및 시기를 고려하여, 생존과 인간 암 샘플 중 CD39 및 CD73 유전자 발현을 상관짓는 연구를 도시한다. 도 13A는 난소암에서의 결과를 도시하며, 특히 암 샘플 중 낮은 CD39 발현은 난소암에서 더 높은 생존 확률과 상관있으며, 또한 난소암에서 보다 낮은 생존 확률과 CD73의 높은 발현의 상관성을 도시한다. 도 13B는 식도암에서의 결과를 도시하고, 특히 암 샘플에서 낮은 CD39 발현은 식도암에서 더 높은 생존 확률과 상관있으며, 또한 식도암에서 보다 낮은 생존 확률과 고발현 CD73의 상관성을 도시한다. 도 13C는 위 선암종에서의 결과를 도시하고, 특히 암 샘플에서 낮은 CD39 발현은 위암에서 더 높은 생존 확률과 상관성이 있고, 또한 위암에서 보다 낮은 생존 확률과 고발현 CD73의 상관성이 도시된다.
