  • Molecular Farming
  • Plant Biotechnology

Background:

  • Molecular farming in plants offers benefits but faces challenges like genetic instability and containment issues.
  • Plant-specific glycosylation can cause allergic reactions in humans receiving pharmaceuticals.
  • Existing cell-culture systems have limitations in protein production.

Purpose of the Study:

  • To evaluate moss bioreactors as a system for recombinant protein production.
  • To leverage moss's unique genetic modification capabilities for pharmaceutical development.
  • To address plant-specific drawbacks in molecular farming.

Main Methods:

  • Utilizing the moss Physcomitrella patens as a bioreactor system.
  • Employing homologous recombination for targeted gene disruption in moss.

  • Comparing protein yields with other cell-culture systems.

    • Main Results:

    • Moss bioreactors provide benefits of molecular farming while avoiding plant-specific disadvantages.
    • Protein yields are comparable to other cell-culture production systems.
    • Targeted gene knockout in moss can reduce plant-specific glycosylation, minimizing allergic reactions.

    Conclusions:

    • Moss offers a robust platform for recombinant protein production with enhanced safety.
    • The unique genetic tractability of moss enables 'humanization' of pharmaceuticals.
    • Physcomitrella patens presents a promising alternative for producing therapeutic proteins.
