viral nanoparticles for in vivo tumor imaging

나노 소재의 사용은 재료 과학 및 의학에 혁명을 할 수있는 가능성이 있습니다. 현재, 서로 다른 나노 입자의 수​​는 이미징 및 치료에 응용 프로그램에 조사하고 있습니다. 식물에서 파생 바이러스 성 나노 입자 (VNPs)가 정의 크기와 모양으로 자기 조립 bionanomaterials으로 간주 할 수 있습니다. Steinmetz 연구실에서 조사중인 공장 바이러스는 직경 30 nm의 아르 둘 다 Cowpea 모자이크 바이러스 (CPMV)와 Brome 모자이크 바이러스 (BMV)에 의해 형성 icosahedral 입자가 포함되어 있습니다. 우리는 또한 다음과 같은 식물 바이러스로부터 파생 된 막대 모양과 filamentous 구조를 개발하고 있습니다 : 18 나노 미터로 300 nm의 크기, 그리고 filamentous 입자 515를 형성 감자 바이러스 X (PVX)로 강성 봉을 형성 담배 모자이크 바이러스 (TMV), 길이, 폭 13 나노 미터의 나노 미터는 (독자는 심판이 판결이라고합니다. VNPs에 대한 자세한 내용은 1, 2). planta에 대규모로 쉽게 제작 할 수 매우 안정적이고 biocompatible 있습니다. 또한, VNPs는 특히 유전자 변형 또는 화학 bioconjugation 방법 3을 사용 설계 할 수 있습니다 &quot;프로그램&quot;단위입니다. VNPs의 구조는 원자 해상도로 알려져 있으며, 수정은 원자 레벨 4, 현재의 최첨단 기술과 합성 나노 소재를 사용하여 달성 할 수없는 제어 수준의 공간적 정밀도로 수행 할 수 있습니다. 이 논문에서, 우리는 CPMV, PVX, TMV, 그리고 Vigna ungiuculata와 Nicotiana benthamiana 공장에서 BMV의 전파에 대해 설명합니다. 각 VNP에 대한 추출 및 정제 프로토콜은 주어집니다. 정화되고 화학적으로 라벨이 표시된 VNPs의 특성에 대한 방법은 설명되어 있습니다. 본 연구에서는, 우리는 채널에 초점을emical fluorophores과 VNPs의 라벨 (예를 들면, 알렉사 형석 647) 및 폴리에틸렌 글리콜 (PEG). 염료는 추적 및 5-10 VNPs의 확인을 용이하게하고, 자신의 pharmacokinetics 8,11을 향상하는 동안 PEG는 proteinaceous 나노 입자의 immunogenicity을 감소시킨다. 우리는 마우스 이종 이식 종양 모델을 사용 PEGylated VNPs의 유도 종양을 보여줍니다. 마에스트로 이미징 시스템을 사용하여 조직 예 생체의 형광 이미징, 균질 조직의 형광 정량화하고, 공 촛점 현미경의 조합이 biodistribution을 연구하는 데 사용됩니다. VNPs는 reticuloendothelial 시스템 (RES)를 통해 해제되며, 추적 종양이 향상된 투자율 및 유지 (EPR) 효과를 통해 수동적으로 12 달성된다. VNP의 나노 기술은 강력한 플러그 앤 플레이 이미지에 기술하고 생체 내 질병의 사이트를 취급합니다. 우리는 더에 약물 cargos 및 임상 - 관련 영상 moieties뿐만 아니라 조직 별 리간드를 수행 할 VNPs를 개발하고 있습니다암과 심장 혈관 질환에 overexpressed 분자 수용체를 타겟팅합니다.
