美国哈佛大学干细胞研究所的Vandenberghe LH教授近日在在PLoS One杂志上发表了一项有趣的工作,他们研究了腺相关病毒(AAV)靶向眼前节的能力,最终发现,Anc80L65能够克服scAAV基因组障碍,具有靶向小梁网状组织TM和角膜的能力。

美国哈佛大学干细胞研究所的Vandenberghe LH教授近日在在PLoS One杂志上发表了一项有趣的工作,他们研究了腺相关病毒(AAV)靶向眼前节的能力,最终发现,Anc80L65能够克服scAAV基因组障碍,具有靶向小梁网状组织TM和角膜的能力。

腺相关病毒(AAV)被广泛用作视网膜基因治疗的基因递送载体,但其靶向眼前节的能力很少被研究,然而这蕴含着巨大的治疗机遇。先前的研究认为,自我递送的(sc)AAV对于从角膜到小梁网状组织(TM)的转导至关重要,但其限制性因素是其递送基因的大小,这可能是由于第二链合成中受阻造成的,而第二链的合成被认为是发挥功能所必须的。

在他们的工作中,他们研究了几种衣壳中为单链(ss)基因组的AAV病毒,以克服屏障,提高靶向角膜内皮和小梁网状组织的能力。 他们在体外对AAV2,8和最近合成的称为Anc80L65的AAV进行了研究,同时通过小鼠体内注射的方式,在体内也对这项病毒进行了研究。

他们的结果表明,在人类小梁网状组织(HTM)永生化细胞系等细胞系中,scAAV2在体外表现出优异的感染性; Anc80L65在单次腔内注射后,可以有效得转导至小鼠眼前节的所有组分,包括小梁网状组织、角膜基质和内皮细胞。这些结果表明,Anc80L65能够克服scAAV基因组障碍,具有靶向小梁网状组织TM和角膜的能力。这项研究扩大AAV在眼前段基因转导的潜在实验和治疗应用。
