Science子刊:Lrrk2等位基因在小鼠的微生物感染过程中以性别依赖的方式调节炎症
富含亮氨酸的重复激酶-2 (leucine-rich repeat kinase-2,LRRK2)基因的变异与帕金森病、麻风病和克罗恩病(以炎症为重要组成部分的三种疾病)有关。LRRK2在粒细胞和CD68阳性细胞中高表达,可能具有先天免疫功能。[查看]

Neurology:太低的LDL胆固醇可能会增加出血性中风的风险
目前的指南建议降低胆固醇,以降低心脏病风险。在一项新的为期9年的研究中,来自中国和美国的研究人员研究了低密度脂蛋白胆固醇(LDL)---通常称为“坏”胆固醇---与出血性中风之间的关系,结果发现如果胆固醇下降过低,这可能会增加出血性中风的风险。当血管在大脑中爆裂时,这种类型的中风就会发生。相关研究结果于2019年7月2日在线发表在Neurology期刊上,论文标题为“Low-density lipoprotein cholesterol and risk of intracerebral hemorrhage”。[查看]

Lancet Neurol:研究揭示了帕金森的大脑根源
伦敦国王学院的研究人员在病人出现任何帕金森相关的症状之前很多年发现了帕金森病在大脑中最早的症状。该研究结果发表在《The Lancet Neurology》杂志上,它挑战了传统的疾病观点,并可能导致开发筛查工具识别最危险的人群。[查看]

Acta Neuropathol:揭示帕金森病在脑细胞之间扩散新机制
在一项新的研究中,来自瑞典林雪平大学、卡罗林斯卡研究所、乌普萨拉大学和德国埃尔兰根大学医院的研究人员发现,神经细胞之间的较小通道参与了一种新发现的关于帕金森病如何在大脑中扩散的机制。这些结果表明有害的蛋白聚集物或者说沉积物能够结合通道形成蛋白并“搭便车”,并以这种方式扩散至健康细胞。相关研究结果近期发表在Acta Neuropathologica期刊上,论文标题为“Binding of α-synuclein oligomers to Cx32 facilitates protein uptake and transfer in neurons and oligodendrocytes”。[查看]

【新品发布】糖尿病领域新秀—Exendin-4 酶免试剂盒全新上市
Exendin-4由39个氨基酸残基组成,与胰高血糖素样肽1(GLP-1)有53%的同源性,是GLP-1受体激动剂,与GLP-1类似,Exendin-4可调节血糖浓度,但GLP-1的半衰期仅有2min,而Exendin-4半衰期却长达9.57h,因此在治疗2型糖尿病方面具有广阔的前景。西宝生物可提供用于相关药发生产的Phoenix Pharmaceuticals品牌Exendin-4 (Heloderma suspectum) EIA Kit用于EIA酶免疫实验,用于实验室快速检测艾塞那肽。订购咨询热线:400-021-8158![查看]

致命罕见病有望迎来首款基因疗法 已启动临床试验
日前,基因疗法公司Myonexus Therapeutics宣布启动一项评估新型基因疗法MYO-101的临床试验,用于治疗β-肌聚糖病(LGMD2E)。该公司致力于与美国国家儿童医院(Nationwide Children’s Hospital)的基因疗法中心以及Sarepta Therapeutics合作,为肢带型肌营养不良症(LGMD)开发首个矫正基因疗法。他们的目标是向骨骼肌和心肌中递送一种基因,使β-肌聚糖(β-sarcoglycan)实现有力的功能性表达,该蛋白质的缺乏会导致LGMD2E。该试验中第1队列的首位患者于10月开始接受治疗,估计其余患者将在今年内完成治疗。[查看]
