澳大利亚和美国研究人员日前在美国《细胞》杂志上发表报告说,他们在小鼠体内发现一种和肾病相关的全新病毒,有望为治疗慢性肾病和儿童遗传性肾病提供新思路。

慢性肾病包括肾炎、肾病综合征、膜性肾病等慢性肾脏疾病,若未及时发现治疗,病情可能发展为慢性肾功能不全、肾衰竭,最终形成尿毒症。目前,慢性肾病的治疗方式主要包括药物治疗和食疗,晚期患者大多需要透析或肾移植。

澳大利亚百年研究所与美国同行合作进行的动物实验发现,一些免疫缺陷型小鼠在中年时就会死去,远小于其预期寿命。进一步调查显示,这些小鼠死于肾衰竭。研究人员随后通过DNA(脱氧核糖核酸)测序技术确认,小鼠的肾衰竭源于其体内一种全新的细小病毒。细小病毒是极小病毒,如果免疫系统健全,这类病毒通常呈良性。

这种细小病毒对肾脏具有高度特异性。论文第一作者本·勒迪格在新闻公报中说:“这一新发现为研究病毒相关性肾病提供了新视角。”接下来研究人员有望利用这种病毒的表面蛋白开发出基因疗法,用于治疗儿童遗传性肾病。

尽管目前尚不清楚这种特殊病毒从何而来,但研究小组认为,这种病毒非常普遍,野生和实验室的小鼠群体可能都携带,研究人员只是借助最新的基因测序技术才得以发现它。

美科研团队研发“迷你大脑” 或可取代医用小白鼠

据香港《文汇报》2月14日报道,美国约翰霍普金斯大学研究团队近日用人体干细胞研发出“迷你大脑”,“迷你大脑”内含构成神经的“神经元”,还可一次制造数百个,有望取代药物测试中白老鼠等动物的角色,这不单可解决人道问题,还可取得更好的测试结果。研究人员已设立公司,希望最快在2016年秋制成首批产品。据报道,研究人员在12日提交给美国科学促进会的论文称,“迷你大脑”用采自皮肤的“诱导性多功能干细胞”(iP

美国人道主义团体持续向动物实验发起挑战

公众可以推动民心所向,但我们最终还是需要科学家改变想法。 Justin Goodman正在他的“战场”——位于华盛顿特区家中的书桌前工作。 图片来源:PAUL FETTERS 坐在距离美国首都华盛顿特区以北仅有数公里的家里的一张木桌前,Justin Goodman正在进行一场抵抗动物实验的战役。今年34岁的Goodman有些瘦削,蓄着略显凌乱的胡须,剃了光头,身上刻满了色彩斑斓的

Elsevier/Bayer的研究发现可以减少动物实验

Elsevier和Bayer的分析小组对安全报告数据进行的新分析发现,一些动物测试比其他动物测试更能预测人类的反应。这项大型研究 - 对欧盟和美国监管机构报告的160多万次不良事件进行了研究 - 发现,根据所报告的物种和症状,一些动物实验比其他动物实验更能预测人类的反应。这一发现对改善患者安全具有"重大意义",可以帮助研究人员更好地确定哪些检测可能是最合适的,从而有可能减少对动物的不必要检测。El

ELIFE:动物实验显示不同抗疟疾疫苗结合使用效果更佳

英国帝国理工学院研究人员领衔的团队通过动物实验发现,将两种不同的抗疟疾疫苗结合使用,比单独使用任何一种疫苗的抗疟疾效果都更好。

NIH要求动物实验必须考虑两种性别间的差异

具体说是要求临床前研究,或者说疾病治疗效应的动物实验研究必须考虑性别差异。过去在动物实验中,除非是针对女性特殊疾病的研究,多采用雄性动物,一般的解释是雌性存在生理周期,会影响实验结果。其实动物的各种周期都有可能影响实验结果,不是有学者发现实验观察者性别都可以大大影响动物疼痛的感觉吗。更重要的,人类的生理周期更明显,男女的差别更是需要区别对待的基础。总之只采用雄性动物,特别是为寻找和确认药物治疗效果

重大发明!微型生物芯片或将取代动物实验

微型芯片实物图(大小比对于1欧元硬币) 弗劳恩霍夫应用研究发展协会(欧洲最大的应用科学研究机构)最近表示他们已经开发出一种非常有前途的微型生物芯片,能够逼真的模拟人体内复杂的代谢过程,将来或能在药物实验中彻底代替动物模型。 为了证实药物的有效性,动物一直是实验室必不可少的实验模型,因为往往在分离的单一组织或者细胞中测试某种物质的作用是远远不够的。评估药物在机体内的作用是从整体影响的角度来评
