表型提示
MGI:96545Mice homozygous for a knock-out allele exhibit increased susceptibility to bacterial infection, reduced IL1b responsiveness, delayed tooth eruption, decreased susceptibility to experimental autoimmune uveoretinitis, decreased susceptibility to kidney reperfusion injury, and late onset obesity. Homozygosity for a mutation associated with arthritis in human leads to severe sensitivity to collagen antibody-induced arthritis.
IL1R1基因,也称为白细胞介素-1受体类型1基因,编码的蛋白质是白细胞介素-1受体的一种,属于细胞因子受体家族。IL1R1蛋白主要表达于免疫细胞表面,与IL1R2共同构成IL-1受体的复合物,参与介导IL-1信号通路。IL-1信号通路在炎症反应、细胞增殖和分化等生物学过程中发挥着重要作用。

研究表明,IL1R1基因的变异与多种疾病的发生发展密切相关。例如,在IgG4相关疾病(IgG4-RD)中,IL1R1基因的变异与IgG4相关腹膜后动脉炎/动脉炎的易感性相关[1]。此外,IL1R1基因的rs2071374位点与子痫前期的风险相关[2]。在骨坏死中,IL1R1基因的rs10490571和rs3917225位点与股骨头坏死的易感性相关[3]。在慢性疼痛中,IL1R1基因的表达与免疫微环境、免疫检查点、免疫激活基因、免疫抑制基因、趋化因子和趋化因子受体等密切相关,可能成为癌症生物标志物[4]。在儿童哮喘中,IL1R1基因的rs949963位点与哮喘易感性相关,并可能影响血清中IL1R1的表达水平[5]。在膝骨关节炎中,IL1R1基因的rs956730和rs3917225位点与膝骨关节炎的风险相关[6]。

此外,IL1R1基因还与肿瘤微环境中的成纤维细胞密切相关。研究发现,通过基因编辑技术敲除小鼠肿瘤相关成纤维细胞中的IL1R1基因,可以观察到肿瘤微环境中细胞状态的变化[7]。IL-1β是肿瘤微环境中多种细胞类型产生和分泌的细胞因子,其表达和成熟受基因多态性和细胞环境的影响。IL-1β在肿瘤发生发展中具有多效性作用,包括对免疫细胞、血管生成、癌细胞增殖、迁移和转移的影响[8]。IL-1β的表达还与非囊性纤维化支气管扩张症的发生发展相关,IL-1β表达的巨噬细胞在黏液栓塞中发挥作用[9]。此外,IL1R1基因还是家族性地中海热相关miR-197-3p的靶基因,miR-197-3p在单核细胞和滑膜成纤维细胞中具有抗炎作用[10]。

综上所述,IL1R1基因在多种疾病的发生发展中发挥重要作用,包括IgG4相关疾病、子痫前期、骨坏死、慢性疼痛、儿童哮喘、膝骨关节炎等。此外,IL1R1基因还与肿瘤微环境中的成纤维细胞密切相关。IL1R1基因的研究有助于深入理解炎症反应和肿瘤发生发展的分子机制,为疾病的治疗和预防提供新的思路和策略。
