Int Arch Allergy Immunol:鼻腔内给药IL-27能够减轻鼻过敏性响应和症状

2018-12-17 AlexYang MedSci原创

白介素(IL-27)是Th1响应的一个抑制子,并能够抑制炎症响应。在一个哮喘小鼠模型中,IL-27给药能够减少气管肺泡灌洗和气道高反应中的嗜酸性粒细胞数目。然而,是否IL-27给药能够抑制过敏性疾病和过敏性鼻炎的症状仍旧不清楚。因此,有研究人员调查了体内IL-27给药对鼻症状和过敏性鼻炎的影响。研究人员在利用OVA敏感和诱导的小鼠中进行IL-27鼻腔给药试验。研究发现,与对照PBS鼻腔给药相比,鼻

白介素(IL-27)是Th1响应的一个抑制子,并能够抑制炎症响应。在一个哮喘小鼠模型中,IL-27给药能够减少气管肺泡灌洗和气道高反应中的嗜酸性粒细胞数目。然而,是否IL-27给药能够抑制过敏性疾病和过敏性鼻炎的症状仍旧不清楚。因此,有研究人员调查了体内IL-27给药对鼻症状和过敏性鼻炎的影响。

研究人员在利用OVA敏感和诱导的小鼠中进行IL-27鼻腔给药试验。研究发现,与对照PBS鼻腔给药相比,鼻腔内给药IL-27能够显著的抑制打喷嚏和摩擦鼻子的次数、嗜酸性粒细胞数、颈部淋巴结中OVA特异性T细胞响应、IL-4和IL-5的产生和血清中特异性lgE。另外,IL-10和IL-35的产生、CD25+Foxp3+细胞的比例和Foxp3的基因表达在IL-27处理的小鼠中比那些只接受PBS处理的小鼠显著更高。

最后,研究人员指出,他们首次证明了鼻腔内IL-27给药能够抑制鼻过敏性响应和症状,甚至是在过敏性鼻炎中也有类似的效果,表明了IL-27可能是一个有用的鼻腔治疗药物。

大多数流行病学研究报道过敏性鼻炎(AR)和非过敏性鼻炎(NAR)时只评估了自我报道的流行度,并没有进行客观的测量确定。更多的是,关于中国人口的NAR流行度报道非常少见。因此,最近有研究人员探索了中国人口中AR和NAR的流行度和风险因子,且主要基于临床表现和过敏状态。研究人员进行的是一个基于群体的代表性调查,包括了中国北京的1084名当地居民。研究发现,自我报道的AR流行度为46.8%。基于SPT结
