Science:六篇论文结论相互矛盾 阿尔茨海默氏病特效药争议悬而未决

2013-05-29 Science 生物360

2012年《科学》(Science)杂志曾发表研究指出,癌症药物 Bexarotene 可以用来治疗阿尔茨海默症,但近日有科学家对此发出了质疑。四个独立研究小组在本期《Science》杂志上报告,他们未能完全重复 Bexarotene 的惊人效果。 2012年3月,Gary Landreth 等人发表的研究称,癌症药物 Bexarotene 可以降低大脑中的β淀粉样蛋白浓度,甚至逆转阿尔茨海默症

2012年《科学》(Science)杂志曾发表研究指出,癌症药物 Bexarotene 可以用来治疗阿尔茨海默症,但近日有科学家对此发出了质疑。四个独立研究小组在本期《Science》杂志上报告,他们未能完全重复 Bexarotene 的惊人效果。

2012年3月,Gary Landreth 等人发表的研究称,癌症药物 Bexarotene 可以降低大脑中的β淀粉样蛋白浓度,甚至逆转阿尔茨海默症小鼠的认知障碍。长期以来,人们一直认为β淀粉样蛋白是引发阿尔茨海默症的关键因素。Gary Landreth 等人的研究显示, Bexarotene 仅在72小时之内,就能清除50%的淀粉样蛋白斑块,这些蛋白斑块被认为干扰了大脑功能。上述结果引起了科学界的广泛的关注。

“目前还没有药物有如此强大的效力,因此这项研究也吸引了大量研究者进行重复,”Johns Hopkins大学的神经科学家 Philip Wong 说。

本周《Science》杂志上发表的研究,都未能重现 Bexarotene 对蛋白斑块的作用。不过,有两个研究小组发现,这种药物能够减少可溶性β淀粉样蛋白的水平。此外,美国匹兹堡大学的神经科学家 Radosveta Koldamova 领导团队发现, Bexarotene 治疗可以改善认知能力。

正方

“我们本以为之前的结果可以被复制,” Landreth 对上述结果作出回应,“我们并不知道为何会出现这种情况。”他认为,其他研究团队使用的药物制备方法可能不同,从而改变了 Bexarotene 在大脑中的浓度,甚至改变了它的生物学活性。

Landreth 在回应中强调,至少有研究证实了原始文章的两个关键结论: Bexarotene 可以降低可溶性β淀粉样蛋白的水平,并且能够逆转认知障碍。他指出,对斑块如此关注可能并没有必要。近十年来,一些科学家已经开始质疑,对脑部健康最为危险的到底是斑块还是可溶性β淀粉样蛋白。

在一片争议声中,Koldamova 认为 Bexarotene 的认知改善作用仍然很有应用前景。“患者并不是去医院清除斑块的,而是去治疗记忆力衰退,”她说。

反方

一些研究者们认为,这些互相矛盾的结果,说明在用 Bexarotene 治疗阿尔茨海默症之前还需要进行更多基础研究。“ Bexarotene 的活性机制未能得到证实,”佛罗里达大学医学院的 Kevin Felsenstein 说。他的团队没有发现 Bexarotene 起作用的证据,研究中 Bexarotene 未能降低可溶或斑块型β淀粉样蛋白的水平。

Felsenstein 担心, Landreth 之前的结果可能会引起药物的滥用,因为这种药物是FDA批准用于治疗皮肤癌的,已经在市面上流通了。2012年8月,新英格兰医学杂志(NEMJ)也曾发表文章指出,会有越来越多的人试图使用 Bexarotene 治疗阿尔茨海默症,并敦促医生们等待临床试验的结果。

目前, Landreth 的研究团队已经展开了早期临床试验,在健康志愿者中对 Bexarotene 进行测试。

生长在乡村或更易患阿尔茨海默症

  生活在乡村的人患阿尔茨海默氏症的风险更高   一项新研究日前指出,在乡村地区出生并成长起来的人,晚年患阿尔茨海默症的几率比生活在城市里的人要高两倍多。   虽然引起这一趋势的原因尚不清楚,但科学家表示,获得卫生保健的情况,以及暴露于某些特殊物质等因素,可能在其中扮演了重要角色。   在英国,阿尔茨海默症影响了大约80万人的健康,并且随着人口老龄化,患者数量到2050年还将翻一番。
