Nature子刊:咖啡也能“抗衰老”?

2017-01-18 佚名 生物谷

近日,斯坦福大学医学院的科学家们发现了饮用咖啡和衰老、慢性炎症以及心血管疾病之间的联系。他们将这一结果发表在权威期刊《Nature Medicine》上。 这项多年的研究对100位参与者的血样、调查数据、病史和家族史进行了广泛的分析,发现了一种与人类衰老和随之而来的慢性疾病相关的炎症机制。研究指出,这一炎症过程就像心血管疾病的驱动者,会增加整体的死亡率。人类基因的组成部分核酸的代谢物

近日,斯坦福大学医学院的科学家们发现了饮用咖啡和衰老、慢性炎症以及心血管疾病之间的联系。他们将这一结果发表在权威期刊《Nature Medicine》上。

这项多年的研究对100位参与者的血样、调查数据、病史和家族史进行了广泛的分析,发现了一种与人类衰老和随之而来的慢性疾病相关的炎症机制。研究指出,这一炎症过程就像心血管疾病的驱动者,会增加整体的死亡率。人类基因的组成部分核酸的代谢物在血液中循环会激发这一炎症反应。而咖啡因及其代谢物可以中和这些核酸代谢物的作用,这也许可以解释喝咖啡的人比不喝咖啡的人寿命要长。

这项研究的主要作者,同时也是斯坦福免疫、移植和感染研究所(the Stanford Institute for Immunity, Transplantation and Infection)的咨询副教授David Furman博士指出:“超过90%的非传染性老龄化疾病都与慢性炎症有关。上千份研究证实慢性炎症会导致癌症、阿兹海默病和其他痴呆症、心血管疾病、骨关节炎、甚至抑郁症。”他继续说:“williamhill asia 都知道咖啡因的摄入与长寿有关,很多研究也指出这一联系,williamhill asia 找出了这一联系的可能原因。”

值得注意的是,这一炎症机制只在部分老年参与者中被激发,而那些炎症机制没有被激发的参与者倾向于喝更多的咖啡因饮料。研究者们甚至发现这一炎症机制在这些喝更多咖啡因饮料的老年参与者中被抑制。

为了进一步揭示咖啡因在衰老免疫机制中的作用,研究者们对一项长达10年研究的数据进行了分析。在这项研究中,研究者们对20-30岁的年轻人和另一组60岁以上的老年人每年进行一次调查、采血和病史评估。他们对比了这两组参与者的血样,并发现有两个基因簇的活性与一种叫做IL-1-beta的循环炎症蛋白有关,并且这两簇内的基因似乎彼此协调工作。

研究者们还对比了老年参与者中的两组人群:一组人群的一个或两个炎症基因簇被高度激活,另一组人群的炎症基因簇则只被低度激活。他们发现,基因簇活性高的12个参与者中有9个患高血压,而基因簇活性低的11个参与者中只有1个患高血压。也就是说炎症基因簇活性高的人更有可能有会导致心血管疾病的动脉硬化。

除此之外,85岁以上的炎症基因簇活性高的参与者更有可能在研究过程中去世,他们的血样中也含有更高活性的自由基,以及更高浓度的IL-1-beta和核酸代谢物。而炎症基因簇活性低的参与者更多地报告说家族中至少有一位亲属活过90岁,他们的血样中含有较高的咖啡因及其代谢物(比如茶碱和可可碱)。

研究者将可以激发基因簇活性的核酸代谢物与免疫细胞一起培养,发现IL-1-beta的产量增加。给小鼠注射这些核酸代谢物会引发大面积的全身炎症,并伴随高血压。同时免疫细胞会阻塞小鼠的肾脏,增加肾压。而将咖啡因及其代谢物和核酸代谢物与免疫细胞一起培养时,他们发现核酸代谢物对细胞炎症机制的触发被抑制了。

“这种很多人都喝并且喜欢喝的东西也许可以给williamhill asia 带来非常直接的好处,” 斯坦福免疫、移植和感染研究所的主任和教授Mark Davis博士说:“williamhill asia 揭示的是咖啡因摄入和长寿之间的相关性(而非因果关系)。而且williamhill asia 在实验室测试中更为严格地指出了这种情况的可能机制。”
