使用新的细胞模型,遗传免疫缺陷慢性肉芽肿病的创新基因治疗方法可以在实验室中更快速和成本有效地测试其功效。来自苏黎世大学和苏黎世儿童医院的一组研究人员使用"基因剪刀"CRISPR / Cas9技术成功地实现了这一目标。目的是在不久的将来使用新的方法治疗严重受影响的患者。

慢性肉芽肿病是免疫系统的遗传性疾病。由于基因缺陷,受影响患者的吞噬细胞不能杀死摄入的细菌和真菌,引起危及生命的感染和具有严重不良后果的过度炎症反应。该疾病可以通过从健康供体的骨髓移植形成血液的干细胞来治愈。当没有匹配的干细胞供体可用时,可以在全世界的几个位置进行基因治疗。临床上在患者中使用基因治疗之前,必须在实验室中对人细胞确定治疗的功效,细胞模型对于这一步骤是最重要的。

"基因剪刀"使细胞模型更完善

最近,由苏黎世大学儿童医院苏黎世UZH教授和免疫学部联合主任Janine Reichenbach领导的研究小组开发了一种新的细胞模型,能够更有效地测试新的基因治疗的疗效。儿科医生和免疫学家解释说:"我们使用Crispr / Cas9技术来改变人类细胞系,使血液细胞显示典型的慢性肉芽肿病特定形式的遗传变化"。以这种方式,修饰的细胞在遗传和功能上反映疾病。到现在为止,科学家不得不依靠使用患者的皮肤细胞,他们已经在实验室重新编程为干细胞。Janine Reichenbach说:"这种方法是费力的,但需要相当多的时间和金钱"。使用我们的新测试系统,这个过程更快,更便宜,使我们能够更有效地为受影响的患者开发新的基因治疗"。

已经大约十年前,Janine Reichenbach的团队发起了世界上第一个临床成功的基因治疗研究,用于治疗慢性肉芽肿病儿童,当时由UZH现在的名誉教授Reinhard Seger领导。原理是从患者的骨髓中分离成血干细胞,将病基因的健康拷贝转移到实验室中的这些细胞中,并将基因校正的细胞注入患者的血液中。校正的血液干细胞发现他们回到骨髓,在那里它们移植并产生健康的免疫细胞。

新的基因轮渡使基因治疗更安全

为了将基因的健康拷贝转移到病变细胞中,直到现在,修饰的人工病毒已经用作校正基因的运输载体。尽管治愈主要疾病,使用第一代病毒基因校正系统的基因治疗现在已过时,由于在欧洲研究中的一些患者中恶性癌细胞的发展。Janine Reichenbach的团队目前正在研发一个新的改进的"基因渡轮"。今天,我们处置所谓的慢病毒自我失活基因治疗系统,这是高效的,最重要的是,工作更安全。苏黎世大学儿童医院是三个欧洲中心之一,能够在国际临床I / II期研究中使用这种新的基因治疗来治疗慢性肉芽肿病患者(EU-FP7程序NET4CGD)。

基因治疗的未来:缺陷基因的精确修复

对于Janine Reichenbach的团队来说,这种新的"基础渡轮"只是一个中间步骤。在未来,基因缺陷将不再通过添加功能基因使用病毒"基因渡轮",而是使用基因组编辑精确修复。 Crispr / Cas9也是关键。然而,它需要另外五到六年,直到这种"精确基因手术"准备好临床应用。在苏黎世大学医学的框架内,我们拥有技术,科学和医学知识,为患有严重遗传性疾病的患者更快地开发新的治疗方法。(生物谷Bioon.com)

人体“基因剪刀”抗癌试验首次通过审查

美国国家卫生研究院一个咨询委员会21日批准了首个利用被誉为“基因剪刀”的CRISPR基因编辑技术来治疗癌症的人体临床试验,让这种目前备受关注的生物医学技术在美国距临床试验仅差美国食品和药物管理局批准一步之遥。 美国国家卫生研究院“重组DNA咨询委员会”批准了这项由美国宾夕法尼亚大学提交的临床试验计划。该委员会负责对在美国进行的基因疗法临床试验进行安全及伦理审查。这项试验还需美国食品和药物管

有研究发现,人体内本该攻击某些病毒的T细胞表面存在能给病毒“带路”并引发感染的受体。为堵住这一“内应通道”,俄罗斯研究人员利用CRISPR-Cas9“基因剪刀”技术,为T细胞找到了抵御某种特定逆转录病毒的新抗体。这种方法或有助于治疗白血病、艾滋病相关药物的研发。人类T细胞白血病病毒Ⅰ型(HTLV-1病毒)是一种逆转录病毒,能引发白血病,且与数种恶性肿瘤发病相关。这种病毒可攻入人体免疫细胞——T细胞
