大多数重组药物蛋白的商业生产涉及使用哺乳动物细胞系,E.大肠杆菌或酵母作为表达宿主。然而,最近的工作已经证明了真核微藻作为光驱动合成此类蛋白质的平台的潜力。在藻类叶绿体中的表达是特别有吸引力的,因为该细胞器含有适合于使用合成生物学方法进行快速工程化的最小基因组;转基因精确地靶向特定的基因组位点并且适合于高水平、受调控和稳定的表达。此外,蛋白质可以被紧密地包含和生物封装在叶绿体中,允许蛋白质的积累,否则对宿主有毒,并开辟了低成本口服生物制剂的可能性。在这篇评论中,我们用最近在藻类叶绿体中成功产生的激素、蛋白质抗生素和免疫毒素的例子来说明这项技术,并强调了未来可能的应用。
Most commercial production of recombinant pharmaceutical proteins involves the use of mammalian cell lines, E. coli or yeast as the expression host. However, recent work has demonstrated the potential of eukaryotic microalgae as platforms for light-driven synthesis of such proteins. Expression in the algal chloroplast is particularly attractive since this organelle contains a minimal genome suitable for rapid engineering using synthetic biology approaches; with transgenes precisely targeted to specific genomic loci and amenable to high-level, regulated and stable expression. Furthermore, proteins can be tightly contained and bio-encapsulated in the chloroplast allowing accumulation of proteins otherwise toxic to the host, and opening up possibilities for low-cost, oral delivery of biologics. In this commentary we illustrate the technology with recent examples of hormones, protein antibiotics and immunotoxins successfully produced in the algal chloroplast, and highlight possible future applications.
