J Allergy Clin Immun:上皮细胞蛋白组分析表明了干扰素诱导的蛋白质在过敏性鼻炎中的必要作用

2017-06-29 AlexYang MedSci原创

季节性过敏性鼻炎(SAR)作为间歇性暴露于季节性花粉中的结果,可以引起鼻子发痒、鼻塞和重复性打喷嚏,并且对生活的品质、工作效率和学校表现具有深远的影响。虽然基因型和环境因素都可能是过敏反应的免疫基础,过敏性鼻炎行管的分子病理阐释仍旧不完全清楚。为了回答这些问题,最近,有研究人员收集了花粉季节时和花粉季节后,来自29名SAR病人和31名对照的鼻上皮刷样本。研究人员进行了基于轨道阱的,倒置免标签定量蛋

季节性过敏性鼻炎(SAR)作为间歇性暴露于季节性花粉中的结果,可以引起鼻子发痒、鼻塞和重复性打喷嚏,并且对生活的品质、工作效率和学校表现具有深远的影响。虽然基因型和环境因素都可能是过敏反应的免疫基础,过敏性鼻炎行管的分子病理阐释仍旧不完全清楚。为了回答这些问题,最近,有研究人员收集了花粉季节时和花粉季节后,来自29名SAR病人和31名对照的鼻上皮刷样本。研究人员进行了基于轨道阱的,倒置免标签定量蛋白组方法和多变量分析来鉴定在四个样品组中差异化表达的蛋白。

研究鉴定了总共133个差异化蛋白,最显著具有代表性的功能分类为干扰素1信号。CST1和PRNT3两个蛋白中,前者保护过敏原蛋白酶活性,后者在上皮屏障功能中具有作用。并且,这两个蛋白在SAR和对照组中具有丰度差异,还不考虑季节影响。更多的是,IFIT1、CST1和IFIT3在SAR组和对照组中受不同的调控,并且在秋天到春天季节交替中,具有相反的丰度动态变化。最后,研究人员指出,在SAR中,干扰素类型1调控蛋白并且可以作为生物标记,还在SAR病理中具有潜在的重要角色。更多的是,当与SAR病人比较,健康组个体表现出不同的蛋白组响应,这也许证明了是疾病预防的治疗靶标。

J immunol:肠道上皮细胞损伤引发肠炎的分子机制

肠道上皮细胞是保护人体的一道重要的屏障。上皮细胞的损伤及后续引发的屏障功能的损坏都会最终导致炎症反应的发生,包括IBD等等。因此,上皮细胞的自我损伤修复对于重建肠道屏障以及组织的稳态调节具有重要的意义。粘膜伤口的愈合依赖于上皮细胞的增殖以及迁移。与免疫细胞以及成纤维细胞不同,上皮细胞的迁移是聚

PLOS ONE:为什么乳腺癌患者更容易出现肺部转移?原因在于ELF5!

乳腺癌是美国女性最常患的癌症。CDC报告,2012年美国共有224147名女性被诊断为乳腺癌,其中41150人死亡。这些数据不断警示我们深入探究乳腺癌的产生机制。除此之外,研究人员希望研制出相关药物以帮助女性抵制这种普遍发生的肿瘤。加文医学研究所的工作人员经过研究之后将原因归于一个特定的基因——ELF5。 ELF5是一个转录因子,因此,在某些特定信号的刺激下ELF5因子对某些基因可起到开关作用。E

Cell Death & Diff:炎症小体在上皮细胞凋亡中的作用

NLRP3是一类天然免疫的信号识别分子,它同时是天然免疫细胞中炎症小体的组成成分。病原体的感染以及自身组织的损伤都能够引起NLRP3的激活,激活后的NLRP3进一步引发ASC与caspase-1的结合并形成炎症小体。越来越多的研究表明NLRP3炎症小体能够激活caspase-8或者caspase-11。Caspase-8是细胞凋亡信号通路的关键分子,细胞表面死亡受体TNFR1或CD95的激活会引发

Nature:为什么细胞过密,状态就不好了?

如今,来自新加坡生物力学研究所(MBI)和法国Jacques Monod研究所(IJM)、国家科学研究中心(CNRS)、巴黎狄德罗大学,以及英国牛津大学居里研究所的研究学者们从人工培养的单层上皮细胞那里得到了一些重要启示。细胞层是一个具有物理性破绽的结构,这些破绽导致了部分细胞的“无辜”死亡。组织中经常发生细胞溢出现象。损伤、凋亡、死亡的细胞会被组织踢出来,就连正常健康的细胞有时也会被排挤出来。目

Nature:重磅!揭示上皮细胞数量维持不变机制

美国犹他州大学Huntsman癌症研究所(HCI)的科学家今天在《Nature》杂志上发表文章,介绍上皮细胞如何更新,保持细胞分裂和细胞死亡之间的数目恒定。上皮细胞组成的皮肤覆盖了内部器官,在器官上形成一道保护屏障,使其可以正常地发挥作用。不过,上皮中的细胞以非常快的速度更新。为了维持健康的细胞密度,分裂和死亡的细胞数量必须相同。如果这种平衡被打破,炎性疾病或癌症就会发生。这项研究的领导者,Hun

Thorax:肿瘤相关中性粒细胞和上皮PTEN的缺失可促进MMP-9的表达

肺部疾病中的基质金属蛋白酶-9(MMP-9)表达增加,蛋白酶可以促进气道重塑。虽然肺癌和COPD的发生都与MMP-9的表达增加相关,但是促进MMP-9表达的细胞和分子机制尚不十分清楚。近期,一项发表在权威杂志Thorax的研究发现在非小细胞肺癌(NSCLC)合并COPD的患者的肿瘤内,MMP-9的转录物相对于临近的无肿瘤组织增加。 MMP-9基因表达和免疫组织化学鉴定显示,肿瘤相关的中性
