    • Disclosed and claimed are vectors having enhanced expression and methods for making and using them. Enhancement of expression is from substantially co-temporal expression of at least one first nucleic acid molecule and at least one second nucleic acid molecule. The second nucleic acid molecule encodes a transcription factor or a translation factor or a transcription factor and a translation factor. The contemporaneous expression can be from operably linking the first and second nucleic molecules to a single promoter, or from operably linking the first nucleic acid molecule to a first promoter and the second nucleic molecule to a second promoter wherein the first and second promoters function substantially contemporaneously. Thus, the first and second nucleic acid molecules can be at the same locus in the vector, or at different loci. The second nucleic acid molecule can encode: one transcription factor or more than one transcription factor; or one translation factor or more than one translation factor; or at least one transcription factor and at least one translation factor. The transcription factor can be from vaccinia H4L, D6, A7, G8R, A1L, A2L, H5R, or combinations thereof. The translation factor can be from a K3L open reading frame, an E3L open reading frame, a VAI RNA, an EBER RNA, a sigma 3 open reading frame, a TRBP open reading frame, or combinations thereof. The vector can be a poxvirus such as an attenuated poxvirus, e.g., NYVAC, or ALVAC.
    • 披露和要求保护的是具有增强的表达的载体和用于制备和使用它们的方法。 表达的增强来自至少一种第一核酸分子和至少一种第二核酸分子的基本上同时表达。 第二核酸分子编码转录因子或翻译因子或转录因子和翻译因子。 同时表达可以是将第一和第二核酸分子可操作地连接到单个启动子,或者可操作地将第一核酸分子与第一启动子连接,而将第二核酸分子可操作地连接到第二启动子,其中第一和第二启动子基本同时起作用 。 因此,第一和第二核酸分子可以在载体中的相同基因座处或在不同的基因座处。 第二核酸分子可编码:一种转录因子或多于一种转录因子; 或一个翻译因子或多于一个翻译因子; 或至少一个转录因子和至少一个翻译因子。 转录因子可以来自牛痘H4L,D6,A7,G8R,A1L,A2L,H5R或其组合。 翻译因子可以来自K3L开放阅读框,E3L开放阅读框,VAI RNA,EBER RNA,西格玛3开放阅读框,TRBP开放阅读框或其组合。 载体可以是痘病毒,例如减毒痘病毒,例如NYVAC或ALVAC。
