Companies leverage this transition to address public criticism and regulatory demands associated with factory farming. Additionally, promoting plant-based alternatives aligns with broader public health initiatives, as these alternatives typically avoid the environmental burdens of intensive animal agriculture.
Challenges and Limitations of Plant-Based Pharmaceuticals
Plant-based pharmaceuticals offer several advantages, but the technology is not without significant hurdles. Key challenges include differences in protein processing, risks related to biosafety, and technical issues in product extraction and purification.
Post-Translational Modifications and Plant Glycosylation
Plants and mammals differ in how they modify proteins after translation, especially when it comes to glycosylation. Plant-produced proteins often carry different sugar groups compared to those from animal cells, which can affect the protein’s structure and function.
Plant glycosylation may result in immunogenic responses in humans or reduce therapeutic efficacy. Synthetic biology and genomics tools have improved the ability to engineer plant lines for more “human-like” glycosylation. However, these modifications are not always precise or comprehensive, and differences can persist.
Pharmaceutical developers may need to screen for unwanted glycoforms or invest in further proteomics analysis. This adds complexity, time, and cost to the drug development process.
Biosafety and Containment Risks
The use of transgenic plants for pharmaceutical production raises several biosafety concerns. Unintentional release of modified plants or genes into the environment could impact local ecosystems or non-target organisms.
Containment strategies, such as greenhouses, dedicated growth chambers, or the use of non-food crops, are required. Yet, containment systems come with high operational costs and logistical challenges, especially at large scale.
There are also regulatory requirements to prevent cross-contamination with the food supply. This can delay approvals, add ongoing compliance costs, and limit which plant species can be used for pharmaceutical production.
Downstream Processing Complexities
Extracting and purifying pharmaceuticals from plant tissues is often more challenging than from mammalian cell cultures. Differences in plant matrices, the presence of secondary metabolites, and variable protein yields can complicate purification.
Standard protocols may not apply, and each plant system may require tailored downstream processing methods. This involves selecting specific solvents, optimizing extraction conditions, and removing plant-derived impurities.
