　　你是否设想过，艾滋病、癌症可以被治愈，秃头、肥胖等“不完美”形体可以轻松被摆脱，甚至真的可以返老还童，寿命不再受时间的束缚？通过基因编辑技术，这些愿景或许都有可能实现。<\/p>\n

　　据英国《独立报》近日报道，科学家们发现了一种新的基因编辑方法，能够修复大脑的“破损基因”。之前报道称，研究人员无法对眼睛、大脑、心脏和肝脏组织的基因进行编辑。但是最新技术让他们首次得以实现这一想法，而且有可能为一系列与老化相关的疾病带来新疗法。<\/p>\n

　　基因编辑技术指能够让人类对目标基因进行“编辑”，实现对特定基因片段的敲除、加入等。它就像一把手术刀，可以根据基因错误的位置进行修改。如果人类能够完全掌握基因编辑技术，面对许多疾病，人类将不再谈虎色变。<\/p>\n

　　根据麻省理工大学医学院的研究，生命编程方式有望根治艾滋病，即利用基因编辑技术将艾滋病毒序列从细胞基因组里删除掉，从而让艾滋病毒从病人体内永久消失。有了这样的利器，艾滋病的威胁将不复存在。<\/p>\n

　　基因编辑技术曾在动物身上进行试验。之前，美国加州大学科学家利用基因编辑技术成功培育出了一种疟蚊品系，能够通过后代将一些疟疾阻断基因快速导入蚊子种群，最终消灭这种昆虫向人类传播疟疾的能力。而哈佛大学研究人员则曾利用基因编辑技术一次性敲除猪细胞中62个逆转录病毒基因，从而扫清猪器官用于人体移植的重大难关，为全世界需要器官移植的上百万病人带来希望。<\/p>\n

　　基因编辑技术从理论到医学领域的实践应用，将为人类带来希望。但是，基因编辑技术的应用也面对许多问题。据外媒报道，基因编辑技术可被用于彻底治疗抑郁症或早年性痴呆症，但专家提醒有可能抹杀患者的创造力。<\/p>\n

　　此外，基因编辑技术的应用也或将引发道德方面的问题。<\/p>\n

　　据英国媒体报道，曾经，“转基因人”这个概念只在电影中出现过。但是，科学家们警告，基因编辑技术如果得到普及，可能会导致一个结果——父母们会利用基因编辑技术“优化”自己的孩子。经过改造的基因必然会遗传给后代。研究人员说：“一旦开始了这种做法，就无法回头了。我们绝不能跨越这个界限。”<\/p>\n","protected":false},"author":5,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[16],"tags":[],"class_list":["post-328512","post","type-post","status-publish","format-standard","hentry","category-science_technology_education"],"_links":{"self":[{"href":"https:\/\/www.sandiegochinesepress.com\/press\/wp-json\/wp\/v2\/posts\/328512","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.sandiegochinesepress.com\/press\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.sandiegochinesepress.com\/press\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.sandiegochinesepress.com\/press\/wp-json\/wp\/v2\/users\/5"}],"replies":[{"embeddable":true,"href":"https:\/\/www.sandiegochinesepress.com\/press\/wp-json\/wp\/v2\/comments?post=328512"}],"version-history":[{"count":0,"href":"https:\/\/www.sandiegochinesepress.com\/press\/wp-json\/wp\/v2\/posts\/328512\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.sandiegochinesepress.com\/press\/wp-json\/wp\/v2\/media?parent=328512"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.sandiegochinesepress.com\/press\/wp-json\/wp\/v2\/categories?post=328512"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.sandiegochinesepress.com\/press\/wp-json\/wp\/v2\/tags?post=328512"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
