Description of cKK-E12

cKK-E12는 siRNA와 mRNA의 효율적인 전달을 위해 지질 나노입자(LNP)를 형성하기 위해 사용할 수 있는 이온화 가능한 지질이다. cKK-E12로 형성된 LNP는 내인성 아폴리포단백질 E(ApoE)에 대한 높은 표면 결합 친화력을 나타내고 간세포에 대한 강한 친화성을 보인다[2]. cKK-E12는 표적 유전자 전달 및 치료, 백신 개발, 분자 영상 및 관련 분야에 일반적으로 적용된다[3,4].

체외 실험에서 cKK-E12 LNP(400ng/mL)로 RAW 264.7 대식세포를 6시간 처리하면 전염증성 사이토카인 IL-6, TNF-α, IL-1α, IFN-β 및 케모카인 MCP-1의 발현이 현저하게 상향 조절된다. 게다가 cKK-E12 LNP(400ng/mL)로 24시간 처리하면 세포사멸, 괴사 및 염증성 세포사멸 세포의 비율이 현저하게 증가한다[5].

체내 실험에서 C57BL/6 쥐에 꼬리 정맥 주사를 통해 Cy5-표지된 mRNA-탑재 cKK-E12 LNP(0.75mg/kg)를 투여하면 1시간 이내에 간(>60%)에 주로 축적된 후 비장, 폐 및 신장에 축적된다[6]. C57BL/6 쥐에 트라스투주맙 mRNA-탑재 cKK-E12 LNP(0.5, 1, 2mg/kg)을 정맥 내 주사하면 24시간 후 혈청 트라스투주맙 수준이 용량 의존적으로 증가해서 2mg/kg 용량에서 약 40µg/mL에 도달한다[7].

Protocol of cKK-E12

세포 실험 [1]:

세포 라인

RAW 264.7 대식세포

제조 방법

RAW 264.7 대식세포를 cKK-E12 LNP (mRNA 용량 400ng/mL)로 6시간 처리한 후 다중 사이토카인 분석법을 사용해서 상청액 내 전염증성 사이토카인(IL-6, TNF-α, IL-1α, IFN-β) 및 케모카인 MCP-1의 농도를 측정하였습니다.

반응 조건

400ng/mL; 6 시간 동안

응용 분야

cKK-E12 LNP 처리는 전염증성 사이토카인 IL-6, TNF-α, IL-1α, IFN-β 및 케모카인 MCP-1의 발현을 현저하게 상향 조절하였습니다.

동물 실험 [2]:

동물 모형

C57BL/6 쥐

제조 방법

C57BL/6 쥐에 꼬리 정맥을 통해 Cy5-표지된 mRNA를 캡슐화한 cKK-E12 LNP(용량 0.75mg/kg)를 주사하였습니다. 주사 후 1시간에 쥐를 희생시킨 후 주요 장기(간, 비장, 폐 및 신장)를 채취해서 IVIS 영상 시스템(Ex/Em: 649/670nm)을 사용하여 체외 형광 영상 촬영을 수행하였습니다. Living Image 소프트웨어를 사용해서 관심 영역을 통해 분석된 총 방사 효율을 기반으로 각 장기의 생체 분포 백분율을 계산하였습니다.

제형

0.75mg/kg; i.v.

응용 분야

대부분의 cKK-E12 LNP는 간(>60%)에 축적된 후 비장, 신장 및 폐에도 일부 축적되었습니다.
