OBJECTIVE To compare the effects of human Trypsin-1 signal peptide and pro-peptide on the expression and secretion efficiency of human Interleukin-25 from mammalian cells. RESULTS The signal peptide and combined signal peptide-pro-peptide sequence of human Trypsin-1 improved the secretion of human IL-25 from 1.7 to 3.2 µg/ml and 1.7 to 8.2 µg/ml, respectively. Deletion analysis identified the minimal Trypsin-1 derived secretion domain that maintains improved human Interleukin-25 production and secretion. The presence of Trypsin-1 pro-peptide sequence does not affect the function of secreted human Interleukin-25. CONCLUSION The Trypsin-1 signal peptide-pro-peptide sequence increased human IL-25 expression and secretion in mammalian cells by fivefold.

使用源自胰蛋白酶-1 的信号肽-前肽域改善 HEK293 细胞中重组人 IL-25 的分泌

目的比较人胰蛋白酶1信号肽和前肽对哺乳动物细胞中人白细胞介素25表达及分泌效率的影响。结果 人胰蛋白酶-1 的信号肽和组合信号肽-前肽序列将人 IL-25 的分泌分别从 1.7 到 3.2 µg/ml 和 1.7 到 8.2 µg/ml。删除分析确定了最小的胰蛋白酶 1 衍生的分泌结构域,该结构域维持改善的人类白细胞介素 25 的产生和分泌。Trypsin-1 前肽序列的存在不影响分泌的人白细胞介素 25 的功能。结论胰蛋白酶-1 信号肽-前肽序列使哺乳动物细胞中人 IL-25 的表达和分泌增加了五倍。
