Bu iletişim kuralı kritik adımlarda anestezi yönetimi, arter/aşılı damar anticoagulation, cerrahi manipülasyon ve aşılı damarın hemodinamik ölçümleri içerir. İki nispeten uzun işlemleri (genellikle 3-3.5 bilateral ven greft için h ve ikili greft iletim için 1,5-2,5 h) içeren bu modelde birden çok hayatta kalma cerrahi anestezi düzgün yönetimi önemlidir.

Ateroskleroz lipid birikimi ve damar duvarındaki inflamasyon gemi lümen, kalp krizi, felç ve bacaklarda1,2kaybı daralma için kurşun Kronik iltihabi bir hastalıktır. Perkütan girişimler (Örn., anjiyoplasti ve stent uygulamaları) ve medikal tedavi (e.g., Statinler ve antiplatelet ajanlar) yararlı tedaviler için ateroskleroz; Ancak, koroner ve periferik dolaşımları ciddi obstrüktif hastalık her iki tedavisinde etkisiz çoğu zaman. Bypass greftleme, otojen damar parçalar, kullanarak şiddetli, diffüz koroner ve periferik damar hastalığı3,4olan hastalar tedavi için ortak bir yordam kalır. Ancak, her iki koroner yerleştirilen Greftler damar ve periferik dolaşımları zavallı uzun vadeli açıklık oranlarına sahip. Koroner dolaşım ven greft 1 yıl ve % 50 tıkandı yaklaşık % 10-20 10 yıl5,6tarafından tıkandı. Periferik dolaşım ven greft başarısızlık oranları 30-%50 5 yıl7de vardır.
Tam yerinde hastalığın bir tedavi gen ürünü teslim edebilirsiniz çünkü gen tedavisi damar grefti başarısızlık önlenmesi için çekici bir yaklaşımdır. Buna göre çok sayıda preklinik çalışmaları ven greft gen terapisi8,9test ettik. Ancak, aslında tüm bu çalışmaların erken zaman puan (2-12 hafta)10,11,12,13,14,15, etkinliğini inceledik 16 , 17. gen tedavisi müdahalelerin dayanıklı sağlayabilir bulgusuna farkındayız genellikle sonuçlar neointimal hiperplazi ve ateroskleroz4geç ven greft hatalarına karşı koruma (yıl). Aşılı damarlarında dayanıklı transgene ifade sağlar ve böylece gen tedavisi müdahalelerin geç gibi erken zaman noktalarda test sağlayan bir yöntem geliştirdik. Dayanıklı transgene ifade elde etmek için HDAd vektörler ve Gecikmeli İletim strateji yöntem içermektedir. HDAd vektörel çizimler sağlamak uzun süreli transgene ifade onlar viral genler tarafından bağışıklık sistemi18,19,transduced hücre tanıma (ve ret)20, önlenmesi, eksikliği nedeniyle 21. Ertelenen iletim (greft yerleştirme sonrası gerçekleştirilen 28 gün) erken aşılama22sonra oluşan arterialization işlemi sırasında transduced hücrelerinin kaybı önler.
Ven greft iletim greft yerleştirme10,11,12,15,16 zamanında tedavi transgene ifade ven greft duvardaki ulaşmak diğer yöntemleri itimat ,17. Seri olarak ölçülen zaman transgene ifade bu yaklaşım kullanarak hızlı bir şekilde iletim22,23sonra azalır. Buna göre bu yaklaşımı kullanarak çalışmalar ven, etkinlik 4 hafta ötesinde değerlendirilmesi ile en değil bir aşılama sonra 12 hafta ötesinde etkinliğini inceleyen değil. Buna ek olarak, bizim Yöntem damar grefti elde stably en az 24 hafta boyunca ve arterler büyük olasılıkla gerçekleştirilen benzer çalışmalar üzerinde tabanlı devam ederse transgene ifade devam ediyor uzun süre22,24. Biz kararlı transgene ifade, bu süre elde hiçbir diğer damar grefti gen terapisi müdahalesi farkındayız.
Bir tavşan modeli bizim yöntem geliştirmek için kullanılır. Diğerleri kemirgenler, tavşan, kullanmış ya da damar sınamak için daha büyük hayvanlar gen terapisi10,11,12,15,16,17,25grefti, 26. Kemirgen modellerle karşılaştırıldığında, adatavşanı are daha pahalı ve daha sıkı düzenleyici gereksinimlerine tabidir. Ancak, daha büyük hayvanlar için karşılaştırıldığında (Örn., domuzlar ve köpekler), adatavşanı are çok daha az pahalı satın almak ve ev ve işlemek daha kolay. Ayrıca, insan damarlarının fizyolojik tavşan damarları benzer27, onlar yeterince büyük perkütan girişimler28,29test etmek için kullanılabilir ve bu yeterli doku sağlar birden çok uç nokta (Örn., histoloji, protein, RNA) bir tek damar numune22,30kullanılarak incelenebilir. Ven greft tavşanlarla yüksek yağlı diyet ile beslenir, buna ek olarak, onlar ven greft ateroskleroz31,32, koroner arter bypass ven greft başarısızlık4,5 ortak bir neden olan geliştirmek . Bu aterosklerotik tavşan ven greft gen terapisi müdahaleler bu yöntemle teslim test etmek için bir substrat olarak hizmet verebilir. Sağlanan Protokolü tavşan ven greft dayanıklı transgene ifade ulaşmak için gerekli teknik becerileri Master müfettişler yardımcı olabilir.

a rabbit model of durable transgene expression in jugular vein to common carotid artery interposition grafts

Ven greft bypass cerrahisi tıkayıcı damar hastalığı için ortak bir tedavidir; Ancak, uzun vadeli başarı greft hatası nedeniyle kan pıhtılaşması, intimal hiperplazi ve ateroskleroz ile sınırlıdır. Bu makalenin amacı iki taraflı venöz interpozisyonu Greftler giyen bir tavşan..... yerleştirerek, sonra Greftler dayanıklı transgene ifade elde bir gen transferi vektör ile transducing bir yöntem göstermektir. Yöntemi normal ven greft homeostazı, genler ve protein ürünleri biyolojik rollerinin incelenmesi sağlar. Ayrıca transgenes ven greft başarısızlık, e.gengelleyebilir faaliyetleri için test sağlar., ister bir transgene ifade neointimal büyüme engeller, damar iltihabı azaltır veya ateroskleroz tavşanların azaltır beslenen yüksek yağlı diyet ile. Bir ilk hayatta kalma ameliyat sırasında sağ ve sol dış juguler ven parçalarını çıkardım ve bilateral ters uç-yan ortak karotid arter interpozisyonu greft yerleştirilir. 28 gün sonra gerçekleştirilen ikinci bir hayatta kalma ameliyat sırasında her greft dolaşımı damar klipleri ile yalıtılmış ve lümen (bir arteriotomy) yardımcı bağlı adenoviral (HDAd) vektör içeren bir çözüm ile doldurulur. 20-min kuluçka sonra vektör çözüm emişli, arteriotomy tamir ve akış geri yüklenir. Damarları bireysel deneysel iletişim kuralları tarafından dikte zaman noktalarda hasat. Greft yerleştirme ve iletim arasında 28 günlük gecikmeye arteriyel dolaşımı için ven greft adaptasyon sağlamak gereklidir. Bu adaptasyon hızlı önce veya hemen sonra aşılama transduced ven greft oluşur transgene ifade kaybı önler. Sağlam, dayanıklı transgene ifade aşılı damarlarında elde etmek için onun yetenek benzersiz bir yöntemdir. Diğer büyük hayvan ven greft modellerle karşılaştırıldığında, tavşan düşük maliyetli ve kolay kullanım avantajları var. Kemirgen ven greft modellerle karşılaştırıldığında, tavşan bol doku analizi için sağlamak daha büyük ve daha kolay manipüle kan damarları var.

Işleç deneysel verileri oluşturmak için bu yöntemi kullanmadan önce yeni bir işleç teknik yeterlilik doğrulanması gerekir. Yeni bir işleç elde etmek gerekir ilk kilometre taşı tutarlı ven greft açıklık ven-aşılama ameliyat ve sonraki Gecikmeli İletim ameliyattan sonra olmuştur. Her ameliyat bir arzu ve ulaşılabilir sonra bitti % 90 açıklık. Açıklık olmayan invaziv genellikle ameliyat sonrası günlük 5-7 gerçekleştirmek Transkutanöz ultrason kullanarak te...
