Abstract
Biologics have become an important area of medical research generating therapeutics essential for the treatment of many disease states. Biologics are defined as biologically active compounds manufactured by living cells or through biological processes termed bioprocessing. Compared to small molecules which are chemically synthesised they are relatively complex and therapeutically specific molecules. Biologics include hormones, vaccines, blood products, monoclonal antibodies, recombinant therapeutic proteins, enzymes, gene and cellular therapies amongst others. For biologic production prokaryotic and eukaryotic cells (mammalian and non-mammalian) are used as expression systems. Eukaryotic expression systems offer many advantages over prokaryotic based systems. The manufacture of high-quality proteins for human clinical use via recombinant technologies has been achieved in yeast and filamentous fungal systems. Advances in bioprocessing such as genetic engineering, bioreactor design, continuous processing, and quality by design has allowed for increased productivity and higher yield in in these non-mammalian eukaryotic systems with protein translation similar to mammalian systems. The application of eukaryotic expressions systems for the manufacture of biologics of therapeutic importance are described herein.
