【通过沉默免疫细胞对抗过敏】昆士兰大学的研究人员距离开发用于治疗炎症性疾病的新药更近了一步,这些疾病包括鼻炎,瘙痒,哮喘,湿疹和皮炎等过敏症。

【通过沉默免疫细胞对抗过敏】昆士兰大学的研究人员距离开发用于治疗炎症性疾病的新药更近了一步,这些疾病包括鼻炎,瘙痒,哮喘,湿疹和皮炎等过敏症。

UQ分子生物学研究所(IMB)和ARC高级分子成像中心的一个团队建立了分子开关,可以控制许多常见的过敏原的免疫反应。

UQ IMB研究员Abishek Iyer博士说,人类免疫细胞通过释放引起炎症并导致过敏反应的组胺和其他化学物质来应对过敏原。

Iyer博士说:“我们可以服用抗组胺药物来缓解一些过敏症状,但这些药物不会影响可能导致慢性疾病(包括哮喘)的炎症根源。

“我们开发的分子转换可以消除人类免疫细胞表面的重要蛋白质,从而控制我们的免疫系统对环境中许多过敏原的反应。

“这是管理一个人发展导致疾病的严重过敏和炎症反应的风险的新方法,但是人类的试验还有一段距离才能实现。”

该小组成员还包括IMB中心炎症和疾病研究所的Rink-Jan Lohman博士,Robert Reid博士和David Fairlie教授。

雷德博士表示,该团队建立了小的化学物质,可以切断触发过敏反应的人类免疫细胞的功能。

发现人类炎性细胞中化合物的试验对于治疗人类炎症性疾病的啮齿动物模型是有效的。

下一步是使用新的小化合物来更好地了解人类免疫应答的分子基础,并为各种过敏,哮喘和其他炎症病症设计更好的治疗方法。

该研究发表在自然通讯科学杂志上。
