Abstract

Background: Recombinant human Interleukin receptor antagonist (rhIL-Ra) can bind to the IL-1 receptor on the cell membrane and reversibly blocks the proinflammatory signaling pathway. However, its effect on allergic rhinitis (AR) and the underlying mechanism remains unknown. This study aims to investigate the efficacy of recombinant human interleukin-1 receptor antagonist (rhIL-1Ra) on AR guinea pigs.

Methods: Guinea pigs were systemically sensitized by intraperitoneal injection and topical intranasal instillation with ovalbumin within 21 days. Animals administrated with saline served as the normal control. The AR animals were randomly divided into the model group and distinct concentrations of rhIL-1Ra and budesonide treatment groups. IL-1β and ovalbumin specific IgE levels were detected by ELISA kits. Nasal mucosa tissues were stained with hematoxylin & eosin (HE) for histological examination.

Results: It was found that the numbers of sneezing and nose rubbing were remarkably reduced in rhIL-1Ra and budesonide-treated guinea pigs. Besides, rhIL-1Ra distinctly alleviated IgE levels in serum and IL-1β levels in nasal mucus, together with decreased exfoliation of epithelial cells, eosinophilic infiltration, tissue edema and vascular dilatation.

Conclusions: rhIL-1Ra is effective in AR guinea pigs and may provide a novel potential choice for AR treatments.

局部重组人白细胞介素-1 受体拮抗剂对豚鼠过敏性鼻炎的治疗潜力。

背景：重组人白细胞介素受体拮抗剂（rhIL-Ra）可与细胞膜上的IL-1受体结合，并可逆地阻断促炎信号通路。然而，它对过敏性鼻炎（AR）的作用及其机制仍不清楚。本研究旨在探讨重组人白细胞介素-1受体拮抗剂（rhIL-1Ra）对过敏性鼻炎豚鼠的疗效：方法：在 21 天内通过腹腔注射和局部鼻内灌注卵清蛋白对豚鼠进行全身致敏。动物以生理盐水作为正常对照。AR 动物被随机分为模型组和不同浓度的 rhIL-1Ra 及布地奈德治疗组。用 ELISA 试剂盒检测 IL-1β 和卵清蛋白特异性 IgE 水平。鼻黏膜组织经苏木精和伊红（HE）染色后进行组织学检查：结果发现，经 rhIL-1Ra 和布地奈德处理的豚鼠打喷嚏和揉鼻子的次数明显减少。此外，rhIL-1Ra 能明显降低血清中的 IgE 水平和鼻涕中的 IL-1β 水平，同时减少上皮细胞脱落、嗜酸性粒细胞浸润、组织水肿和血管扩张。

期刊介绍： Allergy, Asthma & Clinical Immunology (AACI), the official journal of the Canadian Society of Allergy and Clinical Immunology (CSACI), is an open access journal that encompasses all aspects of diagnosis, epidemiology, prevention and treatment of allergic and immunologic disease. By offering a high-visibility forum for new insights and discussions, AACI provides a platform for the dissemination of allergy and clinical immunology research and reviews amongst allergists, pulmonologists, immunologists and other physicians, healthcare workers, medical students and the public worldwide. AACI reports on basic research and clinically applied studies in the following areas and other related topics: asthma and occupational lung disease, rhinoconjunctivitis and rhinosinusitis, drug hypersensitivity, allergic skin diseases, urticaria and angioedema, venom hypersensitivity, anaphylaxis and food allergy, immunotherapy, immune modulators and biologics, immune deficiency and autoimmunity, T cell and B cell functions, regulatory T cells, natural killer cells, mast cell and eosinophil functions, complement abnormalities.
