腺相关病毒(Adeno-associated virus,AAV)是一种安全、高效的中枢神经系统基因转导载体。虽然它目前被广泛用于临床试验,并预计将变得更加普遍,病毒血清型和启动子的适当组合尚未得到充分研究。在这项研究中,我们比较了使用三种不同启动子的AAVrh 10和AAV 5在沙土鼠海马中的转导基因表达,所述三种不同启动子包括巨细胞病毒(CMV)、鸡β-肌动蛋白启动子和CMV立即早期增强子(CAG)以及突触蛋白1(Syn 1)启动子。将携带绿色荧光蛋白(GFP)的腺相关病毒(AAV)基因组1 × 10 ~(10)个,立体定向注射4周龄雄性沙鼠。注射后3周对GFP阳性区域的定量显示AAVrh 10-CMV和AAVrh 10-CAG是最有效的(p< 0.001,与对照相比),AAVrh 10-Syn 1和AAV 5-CMV是次有效的(p< 0.05,与对照相比)。另一方面,AAV 5-Syn 1显示出很少的表达,其仅在注射部位观察到。总之,我们应该注意到,病毒衣壳和启动子的某些组合可能导致基因递送失败,而大多数病毒衣壳和启动子在脑中的转基因表达中会适当地起作用。
Adeno-associated virus (AAV) is an ideal vector for gene transduction into the central nervous system because of its safety and efficiency. While it is currently widely used for clinical trials and is expected to become more widespread, the appropriate combination of viral serotypes and promoters have not been fully investigated. In this study, we compared the transduced gene expression of AAVrh10 to AAV5 in gerbil hippocampus using three different promoters, including cytomegalovirus (CMV), chicken β-actin promoter with the CMV immediate-early enhancer (CAG), and the Synapsin 1 (Syn1) promoter. Four-week-old male gerbils underwent stereotaxic injection with 1 × 1010viral genome of AAV carrying green fluorescent protein (GFP). Quantification of the GFP-positive areas 3 weeks after injection showed that AAVrh10-CMV and AAVrh10-CAG were the most efficient (p< 0.001, compared with the control) and AAVrh10-Syn1 and AAV5-CMV were the next most efficient (p< 0.05, compared with the control). On the other hand, AAV5-Syn1 showed little expression, which was only observed at the injected site. In conclusion, we should note that some combinations of viral capsids and promoters can result in failure of gene delivery, while most of them will work appropriately in the transgene expression in the brain.
