病毒进化出了高效运送基因进入宿主细胞内部的能力,利用这一现象,研究者们能够将病毒进行重新编程,从而能够让其将特定的基因序列导入细胞中,这些载体因此成为了疾病治疗或神经元标记等方面的重要工具。然而,由于病毒载体已经失去的自我复制的能力,因此难以完成大范围的基因运送。特别地,对于大脑来说,由于血脑屏障的存在,因而基因运输十变得更加困难。 The virus evolved the ability to efficiently deliver genes into host cells, allowing researchers to reprogram the virus so that it can introduce specific gene sequences into cells, which have thus become disease treatments or Neuronal markers and other important tools. However, due to the ability of viral vectors to lose self-replication, it is difficult to accomplish a wide range of gene delivery. In particular, for the brain, gene transport ten becomes more difficult due to the presence of the blood-brain barrier.
