通过病毒载体的转导将转基因传递到人类细胞是基因治疗中最令人鼓舞的方法之一。慢病毒衍生载体是这些方法中最有希望的载体之一。当细胞的基因修饰必须在体内进行时,在没有脱靶的情况下对治疗的细胞靶标进行有效的特异性转导是基因治疗的圣杯。对于病毒治疗,这在很大程度上取决于载体携带的表面蛋白的特性。在这方面,慢病毒载体的一个重要特性是有可能被其他病毒的包膜伪型化,从而扩大了它们可以武装的蛋白质范围。在这里,我们讨论这是如何在分子水平上实现的,以及不同的包膜蛋白的特性和潜力,这些包膜蛋白可以用于这些载体的假分型。
Delivering transgenes to human cells through transduction with viral vectors constitutes one of the most encouraging approaches in gene therapy. Lentivirus-derived vectors are among the most promising vectors for these approaches. When the genetic modification of the cell must be performed in vivo, efficient specific transduction of the cell targets of the therapy in the absence of off-targeting constitutes the Holy Grail of gene therapy. For viral therapy, this is largely determined by the characteristics of the surface proteins carried by the vector. In this regard, an important property of lentiviral vectors is the possibility of being pseudotyped by envelopes of other viruses, widening the panel of proteins with which they can be armed. Here, we discuss how this is achieved at the molecular level and what the properties and the potentialities of the different envelope proteins that can be used for pseudotyping these vectors are.
