Plantibodies. Applications, advantages and bottlenecks

Various strategies have been developed to exploit plants as bioreactors for the production of pharmaceutical antibodies, to engineer antibody-mediated pathogen resistance or to alter the plant phenotype by immunomodulation. Recent research developments focus on the fine-tuning of expression systems and the detailed characterisation of recombinant products, including the implications of plant-specific glycosylation. Meanwhile, the first of these plant-derived antibody products has successfully completed early phase clinical trials.
