2008年初,由上海交通大学第一人民医院黄倩教授和美国科罗拉多大学李川源教授合作,携手北京病毒基因工程重点实验室吴小兵博士研究小组共同完成了目前国际上常用的病毒载体,象腺病毒\腺相关病毒\慢病毒(rAAV2/1, rAAV2, Ad5, Ad5/F35, Lentivirus)等病毒载体在视网膜上的特异性基因转导效率的研究,从而为特殊的视网膜疾病选用特殊的病毒载体进行基因治疗,提供了重要的见地认识!她们的结果发表在Current Eye Research, 33:81–90, 2008
Abstract
The transduction efficiency and cell tropism of viral vectors rAAV2/1, rAAV2, Ad5, Ad5/F35, and Lentivirus were evaluated in retina. All viral vectors achieved efficient transduction in living rat retina. However, each vector showed distinctive efficiency in vitro especially for rAAV2/1, which displayed poor transduction in cultured retinal cells. Distinctive cell-specific GFP expression was observed in vivo and in vitro for the same viral vector. The cell-specific tropism was not strictly correlated with the correspondent distribution of viral receptors in retina. These results provided important insights into the selection of appropriate vectors when specific retinal diseases are considered for gene therapy.
Keywords: gene transduction efficiency; retina; transgene expression pattern; viral vector; viral vector tropism
