首例基因编辑猪肾移植
马萨诸塞州综合医院的外科医生首次将猪肾脏移植到活人体内。3 月 16 日,一名患有终末期肾病的 62 岁男子接受了来自 eGenesis 公司开发的基因组编辑猪的肾脏。人源化猪器官取自一只经过基因工程改造的尤卡坦微型猪,该猪共进行了 69 项基因编辑,旨在提高猪移植器官与人类受体之间的兼容性。基因组的改变分为三类:敲除参与糖抗原合成的三个基因,以避免急性排斥反应;插入参与免疫、凝血和补体调节途径的七个人类转基因;以及使猪内源性逆转录病毒失活,以避免它们传播和整合到受体中。异种器官移植--从动物到人的移植--长期以来一直被认为是解决器官移植长期短缺的潜在办法,但进展缓慢,只有少数异种器官移植在非人灵长类动物体内存活数月的成功例子。近年来,第一个接受联合治疗公司(United Therapeutics)旗下 Revivicor 公司基因编辑猪心脏移植的人存活了两个月;第二个接受移植的人存活了六周。Revivicor 公司对猪进行了 10 项基因修饰,以确保器官不会长得太大,避免血栓,并限制排斥反应。
