What This Study Found

Plant- and microalgae-based biotechnological platforms offer affordable production and non-invasive (oral) delivery strategies for antidiabetic peptides including insulin and GLP-1 RAs.

Key Numbers

How They Did This

Review of biotechnological strategies for producing antidiabetic peptides in plant and microalgae systems, evaluating cost reduction and oral delivery potential.

Why This Research Matters

Diabetes drug costs are a global crisis. Making insulin and GLP-1 drugs in plants could reduce costs by orders of magnitude and eliminate injection barriers.

The Bigger Picture

Plant molecular farming could disrupt pharmaceutical manufacturing for peptide drugs, making treatments accessible in low- and middle-income countries where diabetes burden is growing fastest.

What This Study Doesn't Tell Us

Review of emerging technology — most plant-produced peptides are still in development. Regulatory hurdles, dosing consistency, and stability remain significant challenges.

Questions This Raises

  • ?How soon could plant-produced insulin be commercially available?
  • ?Can plant-produced GLP-1 drugs achieve the same efficacy as synthetic versions?

Frequently Asked Questions

Can plants produce insulin?

Yes — plants and microalgae can be genetically engineered to produce human insulin and GLP-1 drugs. This could dramatically reduce manufacturing costs and potentially enable oral delivery.

Would plant-produced insulin be safe?

Plant-produced peptides must meet the same safety and purity standards as conventionally manufactured drugs. Regulatory frameworks are being developed, and early results show promising quality.
