摘 要:近年来,由于哺乳动物细胞具有对重组蛋白质进行正确折叠、装配和翻译后修饰的优点,利用哺乳动物细胞生产医用蛋白质已成为生物制药产业的重要组成部分。但是利用哺乳动物细胞生产医用蛋白质的产量仍然相对较低,因此,如何提高哺乳动物细胞医用蛋白质产量成为了研究热点。本文仅对构建高效表达载体系统、筛选稳定高表达细胞株、优化转录及翻译过程、优化瞬时表达、改进培养工艺和抑制细胞凋亡等几方面的研究进展作一综述。
    关键词:哺乳动物细胞;表达载体;瞬时表达;培养工艺;细胞凋亡

Abstract: In recent years, because of the advantages of proper folding, assembling and the modification of posttranslation for recombinant proteins, using mammalian cells to produce medical proteins has become an important part of biopharmaceutical industry. However, the yields of medical proteins in mammalian cells are still relatively low. Therefore, a hot research topic focuses on how to improve medical protein production in mammalian cells. In this review, we only summarized the recent achievements in methods for improving medical protein production in mammalian cells, including constructing high-level expression vector system, screening cell lines with stable and high expression, optimizing the transcription and translation, optimizing transient expression, improving culture biotechnology, and inhibiting cell apoptosis.
    Key words: mammalian cells; expression vector; transient expression; culture technology; cell apoptosis
