PNAS:人类外伤性脑损伤的果蝇模型

2013-10-17 EurekAlert EurekAlert

一项研究说,科研人员建立了一种果蝇模型用于研究外伤性脑损伤(TBI)的直接和长期后果。找到外伤性脑损伤(TBI)的有效疗法具有挑战性,这部分是由于治疗结果因为损伤的位置和严重程度以及遗传和环境因素而有很大不同。 为了解决这个问题,David Wassarman及其同事开发了一种外伤性脑损伤(TBI)模型,使用黑腹果蝇(Drosophila melanogaster)这种用于许多人类疾病的成熟的模

一项研究说,科研人员建立了一种果蝇模型用于研究外伤性脑损伤(TBI)的直接和长期后果。找到外伤性脑损伤(TBI)的有效疗法具有挑战性,这部分是由于治疗结果因为损伤的位置和严重程度以及遗传和环境因素而有很大不同。

为了解决这个问题,David Wassarman及其同事开发了一种外伤性脑损伤(TBI)模型,使用黑腹果蝇(Drosophila melanogaster)这种用于许多人类疾病的成熟的模型系统,这些疾病已经有了一系列的复杂的实验工具。这组作者证明了有外伤性脑损伤(TBI)的果蝇表现出了和患外伤性脑损伤(TBI)的人类类似的症状,诸如暂时失能、共济失调、神经退化和死亡。

此外,这组作者的数据表明,只有在主要损伤超过了一个阈值的情况下,由于外伤性脑损伤(TBI)造成的死亡才会发生在24小时内,这个极限值受到了年龄和遗传背景的影响,但没有受性别影响。这组作者说,这些发现提示果蝇可以提供关于人类外伤性脑损伤(TBI)的见解,这可能为治疗干预手段提供新的机遇。
