Title:
サイトメガロウイルスエンハンサーおよびニワトリβ-アクチンプロモーターを含むハイブリッドプロモーターを利用したマイナス鎖RNAウイルスベクターの製造方法
Document Type and Number:
Japanese Patent JP5438149
Kind Code:
B2
Abstract:
The present invention provides methods for producing a minus-strand RNA viral vector, which comprise using a promoter comprising a cytomegalovirus enhancer and a chicken ²-actin promoter, to induce the transcription of the genome RNA of a minus-strand RNA viral vector and the expression of minus-strand RNA viral proteins that form a ribonucleoprotein with the genome RNA. The methods of the present invention enable high efficiency production of highly safe minus-strand RNA viral vectors. The methods of the present invention are particularly useful for producing minus-strand RNA viral vectors that are deficient in envelope-constituting protein genes.
