内容诱导不育的非手术方法将是控制野生动物种群的有用工具。我们的实验室在以活体脑细胞为靶点的方法方面拥有经验,这些载体可以携带有效载荷的抑制性RNA或旨在纠正细胞功能障碍的基因。这些方法的组合/修改可能为设计可用于给猫和狗绝育的方法提供一个有用的框架。为了让这种方法成功,它必须满足几个条件:它需要针对一种对生育至关重要的基因。它必须涉及到一种方法,可以选择性地沉默感兴趣的基因。它还需要通过一种微创的方法提供消音剂。最后,沉默效应需要持续多年,才能有效防止目标人群的扩大。在这篇文章中,我们讨论了这个问题,并简要介绍了我们以前的经验:(I)当分子试剂被输送到大脑中参与生殖控制的区域时,能够扰乱生殖周期;(Ii)当使用新的基因治疗方法系统地输送时,分子试剂能够改善神经元疾病。
ContentsA non‐surgical method to induce sterility would be a useful tool to control feral populations of animals. Our laboratories have experience with approaches aimed at targeting brain cellsin vivowith vehicles that deliver a payload of either inhibitory RNAs or genes intended to correct cellular dysfunction. A combination/modification of these methods may provide a useful framework for the design of approaches that can be used to sterilize cats and dogs. For this approach to succeed, it has to meet several conditions: it needs to target a gene essential for fertility. It must involve a method that can selectively silence the gene of interest. It also needs to deliver the silencing agent via a minimally invasive method. Finally, the silencing effect needs to be sustained for many years, so that expansion of the targeted population can be effectively prevented. In this article, we discuss this subject and provide a succinct account of our previous experience with: (i) molecular reagents able to disrupt reproductive cyclicity when delivered to regions of the brain involved in the control of reproduction and (ii) molecular reagents able to ameliorate neuronal disease when delivered systemically using a novel approach of gene therapy.
