在几种神经变性疾病中会发生大脑错误折叠的蛋白质的聚集。异常蛋白聚集在啮齿类动物和灵长类动物中可以通过脑内接种诱导。确定神经退行性疾病是否能通过输血传播,具有重要的公共卫生意义。

该研究的目的是探讨神经退行性疾病的可能输血传播。

来自瑞典的研究人员进行了一项回顾性队列研究。数据来源于瑞典和丹麦的全国输血登记册。该研究的参与者为在1968-2012年间接受输血的1465845例患者。

多变量Cox回归模型被用来估计任何类型痴呆症的风险比,以及从健康献血者(这些人后来被诊断为这些疾病中的一种)接受了输血的患者的阿尔茨海默病和帕金森症的风险比 vs 那些接受健康献血者输血的患者。研究人员还调查了是否在捐助者的一个子集的受血者神经退行性疾病的发生过剩。作为阳性对照,在丙型肝炎病毒筛查实施前和实施后慢性肝炎的传播也被进行了评估。

在包括的患者中,2.9%的患者接受的输血来自确诊为一种研究神经退行性疾病的供体。无论使用怎样的方法,并没有发现任何这些疾病的传播的证据。接受老年痴呆症献血者的受血者 vs 接受健康献血者的患者发生老年痴呆症的风险比为1.04(95%CI,0.99〜1.09)。阿尔茨海默病和帕金森病相应估计分别是0.99(CI,0.85〜1.15)和0.94(CI,0.78〜1.14)。实施丙型肝炎病毒筛查之前检测到肝炎传播,但筛查之后没有检测到。

该研究的数据并没有提供神经变性疾病传播的证据,并且表明如果传播真的发生了,这也是非常罕见的。

PLoS Biol:对抗神经退行性疾病的新分子NMNAT2被发现

来自印第安纳大学等研究单位的研究人员最近进行了一项研究,他们发现了一些证据表明一种叫做NMNAT2的酶能够帮助对抗阿尔茨海默病等神经退行性疾病造成的不良影响。相关研究结果发表在国际学术期刊Plos Biology上。在美国有超过600万人受到退行性脑部疾病的困扰,据估算仅2010年就有50万人的死亡与阿尔茨海默病的发生有关。因此深入理解神经退行性疾病发病机制,找到对抗该类疾病的方法对老年人的健康有

ADA 2016:神药二甲双胍可降低神经退行性疾病风险

美国糖尿病协会科学会议上称,新的研究表明,二甲双胍可能对神经退行性疾病,包括阿尔茨海默氏症和帕金森,具有长期保护作用。来自杜兰大学的Qian Shi博士说,目前有关二甲双胍和神经退行性疾病的数据是相互矛盾的,有研究表明,二甲双胍可降低认知能力下降的风险,但是也有数据显示,服用二甲双胍的患者认知能力更差,可能是因为缺乏维生素B12,还有研究表明,长期使用二甲双胍会轻度增加阿尔茨海默氏症的风险。目前的

Business Insider:帕金森病新型血液诊断方法准确率高达95%

  (图片摘自www.sciencealert.com) 澳大利亚科学家们最近开发出了一种能够检测帕金森症的新型血液检测方法。目前根据临床试验的数据,该检测方法的准确率高达95%。 该检测方法的工作机制是通过筛选血液中一种关键的生物标记物,从而帮助医生们在患者患病早期进行及时的诊断与治疗。 该项研究是由La Trobe大学的研究者们做出,他们已经得到包括美国Michael J.

PLOS Genet:FUS导致神经退行性疾病致病机制取得新进展

神经退行性疾病已经是医学上公认的难题。无数科学家和生物医药公司都曾在这一领域遭受挫折。然而,随着老龄化社会的进程,这类疾病成为了生命科学无法回避的一个问题。最近,中科院生物物理所的吴瑛课题组在著名期刊PLOS Genetics上发表了题为“FUS Interacts with HSP60 to Promote Mitochondrial Damage”的研究论文,报道了他们在这一领域的最新研究成

Acta Neurol Scand:亨廷顿氏舞蹈病患者卒中发生的流行病学调查

目的:糖尿病和高胆固醇血症是卒中发生的危险因素,并且有报道称患有亨廷顿氏舞蹈病(HD)的患者存在糖和胆固醇代谢的改变。研究人员调查了这类人群卒中的发生率及危险因素。方法:在国家登记册中筛选出HD患者192名。从患者记录中获得卒中发生,无症状性脑梗以及危险因素的数据。结果:五个患者发生缺血性脑卒中,表明发病率为42/100000人每年。13名患者发生无症状性脑梗,2名患者发生出血性卒中,没有发现发生

Nature med:靶向tau乙酰化 为神经退行性疾病治疗找到新希望

来自美国格拉德斯通研究所的科学家们最近发现一种用于类风湿性关节炎的治疗药物--双水杨酯(salsalate)能够有效逆转额颞痴呆(FTD)动物模型中tau相关功能紊乱。Salsalate能够阻止tau在脑中的累积,避免发生类似阿尔茨海默病和额颞痴呆的认知损伤。   近日,相关研究结果发表在国际学术期刊nature medicine上,在该研究中研究人员发现乙酰化的tau蛋白是该蛋
