Application
人白介素-1受体拮抗剂(IL-1RA)的用途：
- 研究白介素(IL)-1β受体对阿霉素(DOX)诱导的细胞衰老的作用
- 抑制IL-1β与受体的结合
- 了解cl-效应下游的自分泌白介素-1β(IL-1β)信号传导在RPS27调控中的作用
Biochem/physiol Actions
白细胞介素-1 受体拮抗剂 (IL-1RA) 抑制 IL-1α 的活性和 IL-1β通过竞争性阻断与其 Ⅰ 型和 Ⅱ 型受体的结合。在治疗上，IL-1RA 可能有助于败血症、恶病质、类风湿性关节炎、慢性粒细胞白血病、哮喘、银屑病和炎症性肠病的治疗。
General description
研究领域：免疫学&细胞因子
白介素-1受体拮抗剂(IL-1RA)是天然的炎性抑制蛋白。IL-1Ra可由角膜上皮细胞、单核细胞、中性粒细胞、巨噬细胞和成纤维细胞生成。重组人IL-1Ra是153个氨基酸残基的17.2kDa蛋白质。

Physical form
20 mM Tris (pH 8.0) 冻干。
Preparation Note
先离心，再开瓶。在水中重悬至浓度为0.1-1.0 mg/ml。请勿涡旋。该溶液可在2-8℃下储存长达1周。 对于长期储存，建议在含有载体蛋白（如0.1％BSA）的缓冲液中进一步稀释，分装为工作体积并在-20°C至-80°C下储存。

Cardiac fibroblasts (CFs) undergo senescence in reaction to different stressors, leading to a poor prognosis of cardiac disease. Doxorubicin (Doxo) is an antineoplastic drug with strong cardiotoxic effects, which induces IL-1β secretion and thus, triggers a potent pro-inflammatory response. Doxo
Exposure of T lymphocytes to leflunomide but not to dexamethasone favors the production by monocytic cells of interleukin-1 receptor antagonist and the tissue-inhibitor of metalloproteinases-1 over that of interleukin-1beta and metalloproteinases.
