    • PURPOSE: An optimizing method of tumor necrosis factor receptor type 2 (TNFR2) is provided to verify if an O-glycosylation site and an N-glycosylation site are unnecessary in TNFR2-Fc and to remove the sites, thereby minimizing side effects of a drug because the sites are smaller than the size of full length TNFR2 protein. CONSTITUTION: A method for improving efficiency of TNFR2 comprises the steps of removing an O-glycosylation site, an N-glycosylation site, or O-glycosylation and N-glycosylation sites. The O-glycosylation site is 202th to 252th amino acids from N-terminal of TNFR2. The N-glycosylation site is 28th, 31st, or 34th amino acid from N-terminal of TNFR2. The 34th amino acid (proline) is substituted with asparagine in the N-glycosylation site.
    • 目的:提供肿瘤坏死因子受体2型(TNFR2)的优化方法,以验证TNFR2-Fc中是否不需要O-糖基化位点和N-糖基化位点,并去除位点,从而最大程度降低药物的副作用 因为这些位点小于全长TNFR2蛋白的大小。 构成:提高TNFR2效率的方法包括除去O-糖基化位点,N-糖基化位点或O-糖基化和N-糖基化位点的步骤。 O-糖基化位点是TNFR2的N-末端的第202位至第252位的氨基酸。 N-糖基化位点是TNFR2的N-末端的第28位,第31位或第34位氨基酸。 第34位氨基酸(脯氨酸)在N-糖基化位点被天冬酰胺取代。

    • PURPOSE: An inflammation-targeting receptor and a drug delivery system for treating inflammatory diseases are provided to ensure excellent inflammation-targeting effect and to deliver a drug into an inflammatory lesion. CONSTITUTION: An pharmaceutical composition for treating inflammatory diseases or immune-modulatory treatment contains a fusion protein as an active ingredient, which contains an inflammatory inhibitor or an immune booster which is linked to a fragment containing an extracellular region of IL21R(interlukin 21 receptor), VcamI(vascular cell adhesion molecule 1), IL2RB(interleukin-2 receptor subunit beta), IL3RA(interleukin 3 receptor, alpha), IL13RA1(interleukin 13 receptor, alpha 1), or CRLF1(cytokine receptor like factor 1). The fragment containing an extracellular region IL21R contains a polypeptide with an amino acid sequence of sequence number 4.
    • 目的:提供炎症靶向受体和用于治疗炎性疾病的药物递送系统,以确保优异的炎症靶向效应并将药物递送至炎性病变。 构成:用于治疗炎症性疾病或免疫调节性治疗的药物组合物含有作为活性成分的融合蛋白,其含有炎症抑制剂或免疫增强剂,其与含有IL21R(白介素21受体)胞外区的片段连接, VcamI(血管细胞粘附分子1),IL2RB(白细胞介素-2受体亚基β),IL3RA(白介素3受体,α),IL13RA1(白介素13受体,α1)或CRLF1(细胞因子受体样因子1)。 含有胞外区IL21R的片段含有具有序列号4的氨基酸序列的多肽。
