Cell:新发现的原生生物让宿主免受肠道细菌感染

2016-10-11 佚名 生物谷

尽管细菌经常是肠道微生物组的明星,但是不断涌现的研究描画出一种更加复杂的情形:来自不同生物界的微生物积极地相互合作或者彼此相互抵抗。在一项新的研究中,来自美国西奈山伊坎医学院的研究人员发现一个例子:一种新发现的原生生物阻止它的宿主小鼠遭受肠道细菌感染。相关研究结果发表在2016年10月6日那期Cell期刊上,论文标题为“Host-Protozoan Interactions Protect fro


尽管细菌经常是肠道微生物组的明星,但是不断涌现的研究描画出一种更加复杂的情形:来自不同生物界的微生物积极地相互合作或者彼此相互抵抗。在一项新的研究中,来自美国西奈山伊坎医学院的研究人员发现一个例子:一种新发现的原生生物阻止它的宿主小鼠遭受肠道细菌感染。相关研究结果发表在2016年10月6日那期Cell期刊上,论文标题为“Host-Protozoan Interactions Protect from Mucosal Infections through Activation of the Inflammasome”。

论文通信作者、西奈山伊坎医学院肿瘤学教授、医学教授Miriam Merad说,“这是一项意外获得的发现,但是也一项重要的发现。这项研究表明当研究肠道微生物组时,超越细菌是多么重要。”

研究人员是在意识到在他们自己的实验设施中培养的小鼠要比从外面的商贩购买的小鼠在肠道中拥有更多数量的免疫细胞。论文第一作者、西奈山伊坎医学院研究生Aleksey Chudnovskiy与博士后研究员Arthur Mortha决定找出为何是这样。当他们对这两组小鼠开展肠道清洗时,他们吃惊地发现来自西奈山伊坎医学院实验设施的那组小鼠含有生活在它们肠道中的有鞭毛的原生动物。DNA测序结果揭示出这种微生物是一种新的原生动物寄生虫,他们将之命名为小鼠三毛滴虫(Tritrichomonas musculis)。

进一步的研究表明当这种原生生物被给予到不含有它的小鼠体内时,这些小鼠在它们的肠道中有数量增加的免疫细胞和水平增加的炎性细胞因子。研究人员着手发现其背后的工作机制。他们发现小鼠三毛滴虫激活小鼠肠道上皮细胞中的炎性体(inflammasome),接着导致细胞因子激活。他们也发现树突细胞是诱导炎症所必需的。为了确定小鼠三毛滴虫的定植是否影响小鼠抵抗感染的能力,他们让小鼠感染上沙门氏菌,发现肠道微生物组含有小鼠三毛滴虫的那些小鼠非常有效地抵抗沙门氏菌感染。Chudnovskiy说,“这种物种的保护效应是非常令人关注的。”

经发现,小鼠三毛滴虫是脆双核阿米巴(Dientamoeba fragilis)---一种在很多人的肠道中发现的寄生虫---的直系同源物名,但是研究人员并不知道脆双核阿米巴是否也有一种保护效应。这就是他们计划要研究的东西。Merad解释道,“来工业化国家的人们到新兴国家旅游时要比本地的人群更容易遭受肠道感染。已知在新兴国家比较常见的原生生物产生抵抗肠道病原体感染的保护效应。”

她补充道,“抵抗病原体的战斗决定了人类的存活,而且具有更强免疫系统的那些人是在感染中存活下来的人。很可能的情形是肠道微生物组是进化过程的一个重要的部分。因此,鉴定出在暴露的环境中赋予肠道微生物组免疫优势的那些共生生物应当有助鉴定出新的治疗药物。”

Science:人体细胞又添新类型,可“清洗”肠道细菌

我们肠道内的微生物群对于机体健康的维持具有重要意义,但若得不到有效调节和控制,则会成为健康隐患,可能引发腹泻、腹胀、炎症性肠炎等病症。 为此,我们的肠道表面分泌有一层保护性的粘液,以防止肠道内细菌直接侵入肠壁组织而引发炎症反应。这些粘液的主要成分为粘蛋白,由肠壁上的杯状细胞(goblet cell)分泌。然而,这层粘液并不是密不通风的,有时也会被少数细菌越过,成为“漏网之鱼”。 ▲肠壁上的

Cell:重磅!一种肠道细菌有望逆转自闭症症状

在一项新的研究中,来自美国贝勒医学院的研究人员报道,缺乏一种特定的肠道细菌物种导致小鼠社交能力不足(social deficit)。这些社交能力不足令人想起人类自闭症谱系障碍(autism spectrum disorder, ASD)的症状。通过将这种细菌物种添加到受影响的小鼠肠道中,研究人员能够逆转这些小鼠的一些社交行为问题。相关研究结果发表在2016年6月16日那期Cell期刊上,论文

Nature:肠道微生物菌群不平衡增加糖尿病风险

目前,科学家们认为导致胰岛素耐受性(insulin resistance)的主要因子是体重超重和缺乏身体活动。一项新的由欧盟资助的一个欧洲-中国团队开展的被称作MetaHit的突破性研究发现特定的肠道细菌不平衡能够导致胰岛素耐受性,从而导致2型糖尿病等健康问题的风险增加。相关研究结果于2016年7月13日在线发表在Nature期刊上,论文标题为“Human gut microbes impact

大便移植可治疗溃疡性结肠炎

2016年5月21-24日在圣地亚哥举行的消化疾病周会议上提出,1/4的溃疡性结肠炎患者在没有使用类固醇的情况下,通过肠道组织愈合或接受粪便微生物群移植后病情大幅改善。 溃疡性结肠炎病因尚未完全阐明,主要是侵及结肠黏膜的慢性非特异性炎性疾病(IBD),常始自左半结肠,可向结肠近端乃至全结肠,以连续方式逐渐进展。临床症状轻重不一,可有缓解与发作相交替,患者可仅有结肠症状,也可伴发全身症状。症状包括直

英媒称,“When Doody Calls”是一家专门清理狗狗粪便的公司。创始人名叫玛丽·艾伦·莱维,这家公司创办于2001年,目前拥有450家客户。这是一个新兴的成长型行业,没有人测算过这个行业的全球规模,但莱维是动物粪便专家协会的理事,该协会目前有90家会员企业,专门在北美各地收集宠物粪便。 据英国广播公司网站7月7日报道,这绝非唯一一家与宠物粪便有关的公司,如果说这个有些“肮脏”的行业有什
