J Immunol:低剂量IL-2能够激发Treg介导的食物过敏耐受

2016-06-09 佚名 生物谷

胸腺来源的调节性T细胞(Treg)占据整个CD4 T细胞群体的5%-10%。Treg的缺失会引发免疫耐受紊乱、自体免疫以及过敏反应。事实上,过敏反应也是由于FoxP3突变引起的Treg功能异常产生的多种临床表现之一。另外,过敏反应较为严重的人群体内Treg的数量与功能也处于异常状态。此外,在小鼠试验中Treg也被证明能够有效治疗由于过敏原引发的免疫扩大反应。这些证据表明Treg对于过敏反应的耐受具

胸腺来源的调节性T细胞(Treg)占据整个CD4 T细胞群体的5%-10%Treg的缺失会引发免疫耐受紊乱、自体免疫以及过敏反应。事实上,过敏反应也是由于FoxP3突变引起的Treg功能异常产生的多种临床表现之一。另外,过敏反应较为严重的人群体内Treg的数量与功能也处于异常状态。此外,在小鼠试验中Treg也被证明能够有效治疗由于过敏原引发的免疫扩大反应。这些证据表明Treg对于过敏反应的耐受具有重要的作用。

IL-2对于Treg的存活,增殖以及功能的发挥具有重要的作用。此前的研究与临床试验表明IL-2能够有效提高Treg的数量与功能,并抑制器官移植手术后的免疫排斥效应。

为了研究IL-2对于Treg以及过敏反应的作用,来自法国巴黎第一大学的Bertrand Bellier课题组进行了深入研究,相关结果发表在最近一期的《Journal of Immunology》杂志上。

首先,作者对小鼠进行了IL-2的注射处理,5天后,研究者们检测了小鼠脾脏以及肠道淋巴结中Treg的数量与功能。结果显示:经过IL-2处理的小鼠脾脏与肠道淋巴结中的Treg的数量有了明显的提升,另外,这一部分细胞的活化程度相比对照组也有了显著上升。

之后,作者对OVA敏感型小鼠进行上述的处理,5天后再给其饲喂OVA,使其产生口服过敏反应。结果显示,经过IL-2注射处理的小鼠有效避免了OVA特异性的过敏反应。此外,作者在花生过敏小鼠模型中也验证了上述结果。

为了探索这一效应是否来源于Treg。作者在上述处理的基础上通过特异性抗体阻断了Treg的活性。结果显示,这一阻断能够明显抑制IL-2注射产生的免疫耐受。

进一步,作者发现IL-2的注射能够改变小鼠体内Th1/Th2的平衡,使得Th2的免疫反应程度降低。另外,该处理还能够降低嗜酸性与嗜碱性粒细胞的聚集,从而降低过敏反应的严重程度。

最后,作者证明IL-2的注射能够针对过敏反应产生长期的有效保护作用(1一个月)。

NEJM:母乳喂养婴儿早期(3个月)引入过敏食物并不能预防食物过敏

引起过敏的食物应何时引入母乳喂养的婴儿饮食中是不确定的。研究人员旨在评估是否在母乳喂养婴儿的饮食中早期引入引起过敏的食物是否会预防食物过敏。研究人员从普通人群中招募1303名完全母乳喂养的婴儿,这些婴儿年龄为3个月,随机将这些婴儿分配接受早期引入的6种引起过敏的食物(花生,鸡蛋,牛奶,芝麻,白鱼和小麦;早期引入组),或接受英国母乳喂养的建议,在大约6个月年龄时引入(标准引入组)。主要成果是1-3岁

Immunity:食物过敏!为什么?

近日,来自辛辛那提儿童医院医学中心的研究人员在国际学术期刊Immunity上发表了一项最新研究进展,他们发现了一种新的细胞类型可能在食物过敏反应的发生中发挥重要作用,这一发现或能解释为什么有些人会产生严重的过敏反应而其他人却不会。   在这项研究中,研究人员发现一种新的细胞类型,他们将其称之为MMC9细胞,这种细胞可以大量产生一种炎症性免疫蛋白--IL-9,放大机体对食物的过敏

几滴血检测食物过敏的严重程度

过敏是一件很痛苦的事情,不仅与美食无缘,有时还有生命危险。美国西奈山伊坎医学院的研究人员开发出一种新型的血液检测,有望预测哪些人会对食物产生严重的过敏反应。这项研究近日发表在Annals of Allergy, Asthma & Immunology杂志上。 在检测食物过敏时,医生通常抽取血液,测定免疫系统产生的过敏原特异性IgE(sIgE)的水平。然而,这些检测并不能预测过敏反应的严重

J Pediatr:食物过敏斑贴实验有效吗?

为了研究儿童食物过敏中心中儿童食物过敏实斑贴实验的准确性,来自德克萨斯西南医学中心的J. Andrew开展了一项回顾性研究,纳入所有2011年9月至2012年12月一家三级儿童食物过敏中心收治的食物过敏儿童。研究内容包括,对食物过敏斑贴实验的费用进行成本分析。研究共纳入了797名患儿,其中284名儿童接受了食物过敏斑贴实验。只有90名患儿有食物过敏史,提示需要食物过敏斑贴实验,有126名患儿没有按

Immunity:人为什么会食物过敏

食物过敏是发达国家常见的免疫疾病,约有6%的儿童与3%的成年人患有各种各样的食物过敏反应。目前对于治疗食物过敏的方法主要是通过口服的方式引导免疫耐受。然而,口服免疫耐受(OIT)并不能维持长期的免疫耐受效果。这一问题的根源还是在于我们对食物过敏本身的机制还不够了解。 口服耐受是一个古老的免疫现象。大多数免疫原在通过伤口感染或人为注射的方式进入体内的时候都会引起免疫反应,而同样的物质经过消
