हम तंत्रिका जीव विज्ञान, ड्यूक यूनिवर्सिटी स्कूल ऑफ मेडिसिन के डिपार्टमेंट और डीन के पद बेसिक साइंस, ड्यूक यूनिवर्सिटी के लिए शुक्रिया अदा करना चाहेंगे । हम भी पांडुलिपि पर टिप्पणी के लिए ड्यूक वायरल वेक्टर कोर के सदस्यों को धंयवाद । प्लाज्मिड pLenti CRISPRv2 को फेंग जांग (ब्रॉड इंस्टिट्यूट) से गिफ्ट किया गया । plasmids psPAX2, VSV-जी, pMD2. जी और pRSV-Rev सहित LV-पैकेजिंग प्रणाली डिडिएर Trono (EPFL, स्विट्जरलैंड) से एक तरह का उपहार था । इस काम के लिए वित्तीय सहायता विश्वविद्यालय के दक्षिण कैरोलिना स्कूल ऑफ मेडिसिन, ग्रांट RDF18080-E202 (बी. के.) द्वारा प्रदान की गई थी ।

a protocol for the production of integrase-deficient lentiviral vectors for crispr/cas9-mediated gene knockout in dividing cells

Lentiviral वैक्टर जीन-संपादन घटकों के लिए उनकी क्षमता के कारण छुरा transducing कोशिकाओं की एक व्यापक रेंज के लिए और जीन अभिव्यक्ति के उच्च स्तर मध्यस्थता कोशिकाओं को देने के लिए एक आदर्श विकल्प हैं । हालांकि, उनके मेजबान सेल जीनोम में एकीकृत करने की क्षमता mutagenicity के जोखिम को बढ़ाता है और इस तरह सुरक्षा चिंताओं को उठाती है और नैदानिक सेटिंग्स में उनके उपयोग की सीमा । इसके अलावा, इन एकीकरण-सक्षम lentiviral वैक्टर (ICLVs) द्वारा दिया जीन-संपादन घटकों की लगातार अभिव्यक्ति संकीर्ण जीन लक्ष्यीकरण की संभावना बढ़ जाती है । एक विकल्प के रूप में, integrase की कमी lentiviral वैक्टर (IDLVs) की एक नई पीढ़ी विकसित किया गया है कि इन चिंताओं के कई पते । यहां CRISPR के लिए एक नया और बेहतर IDLV मंच के उत्पादन प्रोटोकॉल-मध्यस्थता जीन संपादन और सूची में शामिल कदम शुद्धि और ऐसे वैक्टर की एकाग्रता में वर्णित है और उनके transduction और जीन संपादन क्षमता का उपयोग कर HEK-293T कक्षों का प्रदर्शन किया गया । इस प्रोटोकॉल को आसानी से स्केलेबल है और उच्च titer IDLVs है कि इन विट्रो में और vivo मेंtransducing कोशिकाओं में सक्षम है उत्पंन करने के लिए इस्तेमाल किया जा सकता है । इसके अलावा, इस प्रोटोकॉल आसानी से ICLVs के उत्पादन के लिए अनुकूलित किया जा सकता है ।

IDLV-CRISPR/Cas9 वैक्टर की नॉकआउट-दक्षता का सत्यापन हम एक मॉडल के रूप में GFP-व्यक्त 293T कोशिकाओं का इस्तेमाल किया CRISPR की क्षमता को मांय/Cas9-मध्यस्थता जीन नॉकआउट । GFP + कोशिकाओं ०.५ के एक pLenti पर GFP-vBK201a (MOI) के ...
