Bu protokol vivo tümör görüntüleme için VNPs ve uygulamaları kimyasal modifikasyonu için bir yaklaşım sağlar. Burada sunulan hayvan floresan görüntüleme, floresans ölçme ve immunohistokimyasal teknikler biyodağılımını okuyan ve tümör homing değerlendirmek için yararlıdır. Bu teknikler EPR etkisi ile tümörün nanopartiküller erişim konusunda değerli bilgiler sağlamaktadır. Çeşitli analitik yöntemlerle elde edilen sonuçları birleştirerek, VNPs lokalizasyonu ve biyo...

viral nanoparticles for in vivo tumor imaging

Nanomalzemelerin kullanımı malzeme bilimi ve tıp devrim potansiyeline sahiptir. Şu anda değişik nanopartiküller bir dizi görüntüleme ve tedavi uygulamaları için araştırılmaktadır. Bitkilerden elde edilen viral nanopartikül (VNPs) belirlenmiş boyutlarda ve şekillerde ile kendini monte bionanomaterials olarak kabul edilebilir. Steinmetz laboratuarda inceleme altına Bitki virüsleri çapı 30 nm her ikisi de Börülce mozaik virüsü (CPMV) ve Brom mozaik virüsü (BMV) oluşan icosahedral parçacıkları içerir. Biz de şu bitki virüsleri türetilen çubuk şeklinde ve ipliksi yapılar geliştiriyoruz: 18 nm 300 nm boyutlarında ve ipliksi parçacıklar 515 oluştururlar Patates X virüsü (PVX), rijit çubuklar oluşturur Tütün mozaik virüsü (TMV), uzunluk ve genişlik olarak 13 nm olarak nm (okuyucu Refs ifade edilir. VNPs hakkında daha fazla bilgi için 1 ve 2). planta büyük ölçekte kolaylıkla üretilebilir, son derece istikrarlı ve biyouyumlu vardır. Ayrıca, VNPs özellikle genetik modifikasyon veya kimyasal bioconjugation yöntemleri 3 kullanılarak tasarlanmış olabilir &quot;programlanabilir&quot; birimlerdir. VNPs yapısı atomik çözüm bulunmakta olduğu bilinmektedir, ve modifikasyonlar atomik seviyede 4, mevcut teknoloji teknolojileri ile sentetik nano kullanılarak elde edilemeyen bir kontrol seviyesinde uzaysal hassasiyet ile gerçekleştirilebilir. Bu yazıda CPMV, PVX, TMV ve Vigna ungiuculata ve Nicotiana benthamiana bitkilerde BMV yayılımı tanımlar. Her VNP için Ekstraksiyon ve saflaştırma protokolleri verilmektedir. Saflaştırılmış ve kimyasal-etiketli VNPs karakterizasyonu için yöntemler tarif edilmiştir. Bu çalışmada, ch odaklanmakemical florofor ile VNPs etiketlenmesi (örneğin Alexa Fluor 647) ve polietilen glikol (PEG). Boyalar izleme ve 5-10 VNPs tespiti kolaylaştırmak ve onların farmakokinetiği 8,11 artırırken PEG protein nanopartiküller immünojenite azaltır. Biz bir fare ksenogreft tümör modeli kullanılarak Pegile VNPs yuvalandırma tümör ortaya. Maestro Görüntüleme Sistemi kullanılarak dokuların ex vivo floresan görüntüleme, homojenize dokularda floresans ölçme ve konfokal mikroskopi kombinasyonu biyodağılımını incelemek için kullanılır. VNPs retiküloendotelyal sistem (RES) ile temizlenir; homing tümör geliştirilmiş geçirgenlik ve saklama (EPR) etkisi 12 ile pasif olarak elde edilir. VNP nanoteknoloji güçlü bir plug-and-play görüntü teknolojisi ve in vivo hastalık siteleri tedavi. Bu daha fazla ilaç için yük ve klinik olarak-ilgili görüntüleme kısımları gibi doku-spesifik ligandlar taşımak için VNPs geliştirmektedirkanser ve kardiyovasküler hastalık aşırı eksprese moleküler reseptörleri hedef.
