Belirli bir protein aktivitesini etkileyen nerede küçük moleküller tanımlanır temel hedef ilaç bulma, birçok varolan tarama çalışmalarının odak noktası olmuştur. Bu yaklaşım çok sayıda ilaç, ekranlar üzerinde ters bir fenotip, klasik Farmakoloji, dayalı sağlamıştır, ancak klinik olarak etkili1olmuştur ilk sınıfındaki bileşikler belirlenmesinde daha başarılı olmuştur. Bir dezavantajı fenotipik ilaç keşif için uygun hastalık modelleri kullanılabilirliğine da...

Tarama için kullanılabilir deneyleri gelişimi başarı nadir bir hastalık hedeflemek için kullanılan ilaçlar belirlenmesinde esas alır. Hipotez veya hedef tabanlı ekranlar (ters farmakoloji) yararlıdır, ancak hastalığın moleküler temeli detaylı bir anlayış gerektirir. Fenotipik ekranlar (klasik farmakoloji) biyokimyasal yollar ayrıntılı bir anlayış gerekir ama bunun yerine doğru hastalığın patofizyolojisi ayna modelleri geliştirilmesi üzerinde güveniyor. Hedef tabanlı yaklaşımlar için coşku rağmen fenotipik ekranları daha başarılı1olmuştur FDA onaylı ilk sınıfındaki ilaç analizleri ortaya koyuyor. Bu yöntem genel amacı bu eleme yüksek üretilen iş için bir platform kurmak için metabolik karaciğer hastalığının tedavisi için küçük moleküller tanımlamak için kullanılabilir. Birkaç vitro modelleri birincil tetkikine, hepatoma hücreleri ve karaciğer progenitör hücre2gibi tarif edilmiştir. Ancak, bu modellerin çoğu kısıtlamalar bulunmaktadır ve doğru bir şekilde kültür metabolik karaciğer eksiklikleri Patofizyoloji özetlemek yeni modeller için bir ihtiyaç. Son zamanlarda, insan pluripotent kök hücreler gen düzenleme ile kombine-si olmak teklif etmek bile nadir hastalıklar kültür ezelî belgili tanımlık lüzum erişim hastalara en nadide modellemek için bir fırsat doğrudan3. Hasta özel iPSCs kullanımı sırasında nadir karaciğer hastalıklarının tedavisi için küçük moleküller keşfetmek için bir araç kavramsal olarak makul olduğu gibi sadece bu yaklaşım4fizibilite gösteren birkaç rapor ediliyor. Ancak, son zamanlarda IPSC kaynaklı tetkikine başarıyla karaciğer metabolizması5eksiklikleri tedavisi için güvenilemez uyuşturucu tanımlamak için kullanılan bir platform kurduk.
Bu iletişim kuralı 96-şey plakaları hepatosit benzeri hücreleri insan iPSCs ayırt ve küçük moleküller içeren bir kitaplık ekranı için onları kullanarak işlemi açıklar. Ayrıca hiperkolesterolemi metabolik karaciğer hastalığı örnek olarak kullanarak bitiş noktası analizi açıklar. Bu yaklaşım rolünü ve uygulama bağlamında bulaşıcı karaciğer hastalığı, metabolik karaciğer hastalığı, ilaç toksisitesi ve diğer karaciğer bozuklukları, küçük moleküllerin çalışma yararlı olmalıdır.

using human induced pluripotent stem cell-derived hepatocyte-like cells for drug discovery

Hepatosit benzeri hücreler (HLCs) insan indüklenmiş pluripotent kök hücreler (iPSCs) ayırt etmek hepatik metabolizma doğuştan hataları incelemek için yeni fırsatlar sağlar. Ancak, karaciğer hastalığı tedavi etmek için kullanılabilir küçük moleküller tanımlaması destekleyen bir platform sağlamak için yordamı bileşikler binlerce eleme ile uyumlu bir kültür biçimi gerektirir. Burada, 96-iyi doku kültürü plakaları hepatosit benzeri hücreleri insan iPSCs tekrarlanabilir farklılaşma izin tamamen tanımlanmış kültür koşulları bir iletişim kuralı'nı açıklar. Ayrıca, Apolipoprotein B (APOB) düşürmek için yeteneklerini için ekran bileşikler platforma kullanarak örnek bir ailesel hiperkolesterolemi hastanın oluşturulan IPSC kaynaklı tetkikine üretilen sağlamaktayız. İlaç keşif ile uyumlu olan bir platform kullanılabilirliğini araştırmacılar roman karaciğeri etkileyen hastalıklar therapeutics tanımlamak izin vermelidir.
