Nat Commun:自闭症标志:脑部小胶质细胞过度激活

美国约翰·霍普金斯大学和阿拉巴马大学伯明翰分校之间合作利用人类大脑尸检后所获得的数据分析揭示,自闭症患者大脑中显示免疫应答提升。这项研究包括来自72例自闭症患者和对照者的大脑数据。相关研究结论已经发表在Nature Communications杂志上。

获得自闭症有许多不同的原因,但研究发现自闭症都具有相同的下游效应(大脑中免疫应答提升),约翰霍普金斯大学医学院Dan Arking博士说,我们不知道此类免疫反应是否会使病情在短期内变好,还是在长期来看使得疾病糟糕。

自闭症的原因仍是未知的,因此是遗传学家和神经科学家一个重点的研究课题。Arking和他的同事分析样品中(来源于两种不同的组织库中的样品)的基因表达,将自闭症患者与没有此疾病的对照者的基因表达进行比较。

以前的研究已经确定自闭症患者脑和脊髓中神经元细胞异常。在这项研究中,Arking说:研究小组能够聚焦于小胶质细胞,小胶质细胞是帮助大脑抵抗病原体和其他威胁的特定类型细胞。在自闭症者大脑中,小胶质细胞似乎是永远激活的,小胶质细胞应对炎症反应的基因处于开启状态。

Arking注意到,既然我们已经明确遗传因素对自闭症的贡献,我们认为炎症不太可能是自闭症的根本原因。相反,他说,炎症是上游基因突变的下游结果。下一步将是找出是否治疗炎症可以改善自闭症症状。

自闭症患者容易“同病相怜”

“同病相怜”是一个常用的成语,比喻因有同样的遭遇或痛苦而互相同情。京都大学日前发表一份公报称,其副特聘副教授米田英嗣与福井大学和金泽大学的研究人员合作,发现拥有自闭症谱系障碍(Autism Spectrum Disorder)的人,会对拥有同样障碍倾向的人产生共鸣。自闭症谱系障碍患者曾被认为缺乏共鸣能力,不过新成果颠覆了这一看法。研究小组认为,具有自闭症谱系障碍倾向的人有可能更加适合为自闭症谱

空气污染或为自闭症诱因之一

据英国《每日邮报》10月23日报道,研究发现,空气污染可能是自闭症的诱因之一。体内过量的铬和苯乙烯与儿童自闭症谱系障碍(ASD)有关。全球有约1.47%的儿童患有自闭症。研究还发现,在胎儿期以及两岁之前越多接触到高度污染空气,就越容易患上自闭症。 这一研究结果也证实了为什么近几年来,患有自闭症的儿童数量日趋增长。 据报道,该调查围绕美国宾夕法尼亚州西南部一些儿童展开的。其研究结果23日将在美国

Molecular psychiatry:iPS细胞技术助探求自闭症个性化治疗

自闭症有很多类型,科学家近年来一直在探求自闭症的个性化治疗。巴西和美国的科研人员最近利用iPS细胞技术,在自闭症个性化治疗上取得新进展。 iPS细胞的全称是诱导性多能干细胞,科学家通过将某些转录因子导入动物或人的细胞将其“逆转”到早期胚胎发育状态,让细胞重新获得分化成其他细胞的能力。 巴西圣保罗大学和美国加州大学圣迭戈分校的研究人员在最新一期《分子精神病学》杂志上报告说,他们从一名8岁自闭症患

Transl Psych:自闭症相关基因突变已确定

近日,来自英国利兹大学的研究人员通过研究发现了和自闭症特征相关的基因突变,相关研究刊登于国际杂志Translational Psychiatry上。 文章中,研究人员表示,某些自闭症个体机体或存在基因neurexin-II的缺陷,为了调查是否该基因和自闭症的症状相关,研究人员利用缺失基因neurexin-II的小鼠进行研究,结果发现缺失neurexin-II的小鼠的行为特征和自闭症症状非常相

PNAS:西兰花能否缓解自闭症?

麻省儿童医院(MGHfc)和约翰·霍普金斯大学医学院(Johns Hopkins Medicine)的研究人员们进行了一个小型的研究并发现:自闭症患者如果每天摄入一定量的萝卜硫素(一种存在于西兰花、花椰菜和卷心菜等食用植物中的分子),能够缓解其自闭症的一些症状。相关研究报告于今年10月13日,发表在网络版PNAS上。 这项研究选择了44位已被诊断为患有中度到重度的自闭症的男性作为此次研究的样本

Nature:美研究发现自闭症相关基因突变

   最近,由美国加州大学旧金山分校(UCSF)科学家部分带领、涉及世界各地50多个实验室的两项重大自闭症遗传学研究,已经发现了这种疾病相关的几十个基因。研究表明,这些基因中的罕见突变可影响大脑中的通信网络,并损害基本的生物学机制,而这些机制控制着基因是否、何时和如何被激活。 这两项新研究,发表在2014年10月29日的《Nature》杂志,将100多个基因突变与自闭症联系在一
