Transient production of recombinant pharmaceutical proteins in plants: evolution and perspectives

Kopertekh, Lilya GND; Schiemann, Joachim GND

During the last two decades the production of pharmaceutical proteins in plants evolved from proof of concept to established technology adopted by several biotechnological companies. This progress is particularly based on intensive research starting stable genetic transformation and moving to transient expression. Due to its advantages in yield and speed of protein production transient expression platforms became leading plant-based manufacturing technology. Current transient expression methods rely on Agrobacterium-mediated delivery of expression vectors into plant cells. In recent years great advances have been made in improvement of expression vectors, host cell engineering as well as in the development of commercial manufacturing processes. Several GMP-certified large-scale production facilities exist around the world to utilize agroinfiltration method. A number of pharmaceutical proteins produced by transient expression are currently in clinical development. The great potential of transient expression platform in respect to rapid response to emerging pandemics was demonstrated by production of experimental ZMapp antibodies against Ebola virus as well as influenza vaccines. This review is focused on current design, status and future perspectives of plant transient expression system for production of biopharmaceutical proteins
