Using Plants to Create Biopharmaceuticals in Education: Exploring the Path to Innovation
Overview of Biopharmaceuticals from Plants
Biopharmaceuticals are a rapidly growing field of medicine that focuses on developing drug therapies using living sources such as plants. These medications can offer many advantages over traditional synthetic drugs, including lower toxicity and higher specificity, which means they target the disease-causing cells more effectively.
The use of plants to create biopharmaceuticals is not a new concept, and in fact, many drugs used today are derived from plant sources. For example, the first anti-cancer drug, vincristine, was extracted from the periwinkle plant, and the painkiller morphine is derived from the opium poppy. In recent years, the focus has shifted to genetically modifying plants to produce pharmaceutical compounds, which can be both more efficient and sustainable.
The process of creating biopharmaceuticals from plants involves several steps. First, the gene encoding the desired therapeutic protein must be isolated and cloned into a plant expression vector. The vector is then introduced into the plant cell, where the transgene is integrated into the genome and expressed to produce the desired protein. Once the plant has been harvested, the protein must be extracted and purified, which can be a complex and expensive process.
One of the main advantages of using plants to produce biopharmaceuticals is scalability. Unlike traditional small molecule drugs, which are synthesized chemically in a lab, plants can be grown in large quantities relatively easily. This means that once the initial investment in developing the plant-based system has been made, the cost of producing a drug on a large scale can be much lower than for a synthetic drug.
Another advantage of plant-based biopharmaceuticals is the potential for increased safety and efficacy. Traditional synthetic drugs can have off-target effects and may cause toxicity if not administered carefully. Plant-based biopharmaceuticals, on the other hand, tend to be more specific in their targeting and have a lower risk of side effects. They are also less likely to provoke an immune response, which can be a problem with some synthetic drugs.
In conclusion, the use of plants to create biopharmaceuticals represents an exciting and rapidly evolving field of medicine. As our understanding of plant biology and genetic engineering continues to advance, we can expect to see more and more drugs derived from these living sources. Not only do plant-based biopharmaceuticals have the potential to be more effective and safer than traditional drugs, but they can also be produced more sustainably and at a lower cost, making them an attractive option for drug development in the future.
Genetic Modification of Plants to Produce Biopharmaceuticals
Plant-based systems offer a cost-effective and safe solution for producing biopharmaceuticals on a large scale. The process begins by identifying the desired protein or molecule that needs to be produced. The next step involves genetic modification of plants to express the gene of interest. This is done by introducing the target gene into the plant’s DNA. In most cases, the gene of interest is inserted into the plant’s genome using Agrobacterium-mediated transformation or gene gun methods.
Agrobacterium-mediated transformation involves the use of a bacterium called Agrobacterium tumefaciens, which is naturally capable of transferring DNA into plants. The target gene is inserted into a plasmid, which is then introduced into Agrobacterium. The bacterium is then used to infect the plant tissue, and the target gene is transferred into the plant cell.
The gene gun method, on the other hand, involves shooting micro-projectiles coated with DNA fragments into the plant tissue using a high-pressure gun. The DNA fragments penetrate the cell walls and become integrated into the plant cell’s DNA. Both methods have been successfully used to introduce genes into plants for biopharmaceutical production.
Once the target gene is successfully introduced into the plant’s genome, the next step is to select the best-performing plant line that expresses the highest level of the desired protein or molecule. This is done by screening a large population of genetically transformed plants. The best-performing plant line is then propagated by cloning to ensure uniformity of the expressed protein or molecule.
The use of genetic modification in plant-based biopharmaceutical production has several advantages. Firstly, plants are capable of expressing complex proteins with post-translational modifications, which are difficult to produce using microbial systems. Secondly, the cost of production is lower compared to traditional methods, and thirdly, plant-based systems offer the potential for rapid scaling up of production to meet market demand.
Cost-Effective Production using Plants
The cost of biopharmaceuticals production using plants is lower in comparison to other conventional methods. It is because plants, unlike animals, yield a high amount of biomass per acre used for cultivation. The Upfront capital cost of the plant-based production facility is lower than that of animal-based systems.
Moreover, growing plants needs less storage space than housing animals for production. Plants require less water, fewer nutrients, and less energy for production – this reduces the cost of maintenance and cultivation. The cost-effective production process using plants has enabled the production of low-cost biopharmaceuticals that are available to everyone.
Using plants, there is less need for the use of expensive equipment such as bioreactors and high-tech sterile facilities, which leads to cost savings. In addition, the fast-growing nature of plants and ease of cultivation maximizes the production of biopharmaceuticals and the overall return on investment.
Eco-Friendly Production using Plants
The production of biopharmaceuticals using plants is not only cost-effective but also an eco-friendly process. Unlike animal-based systems, plant-based systems do not emit greenhouse gases that contribute to environmental pollution.
Additionally, plants can be grown in various ecological zones, enabling the production of biopharmaceuticals in different regions of the world. Therefore, this process reduces the carbon footprint of transportation and delivery of biopharmaceuticals to different parts of the world.
The cultivation of plants requires fewer chemicals, pesticides, and fertilizers, resulting in a reduced impact on the environment and ultimately public health. In comparison, animals require a high use of antibiotics, hormones, and other pharmaceuticals to combat infections and improve their growth rate. These chemicals can be harmful to human health and end up leaving residues in animal products. Using plants for biopharmaceuticals production eliminates this risk.
Reduced Risks of Transmitting Human Diseases using Plants
Biopharmaceuticals production processes have the potential to transmit human diseases such as prions, viruses, and bacteria. Since animals carry transmissible diseases, the production of biopharmaceuticals using animals poses a risk factor. On the other hand, plants do not carry human pathogenic viruses, leading to reduced risks of human disease transmission.
Using plants for production eliminates the chances of cross-species infection and reduces the risk of human pathogen contamination. Since biopharmaceuticals are used in treating diseases, it is crucial to minimize the risk of contamination. Therefore, biopharmaceuticals production using plants is a beneficial option for ensuring safety and efficiency.
In conclusion, using plants in biopharmaceuticals production is an excellent option for a more cost-effective, eco-friendly, and safer process. The plant-based system of production reduces the rate of human diseases transmission, lowers production costs, and has lesser impact on the environment. As medical needs continue to grow, using plant-based production in the pharmaceutical industry should be a major consideration for sustainable and effective production.
Biopharmaceuticals Produced from Plants: An Overview
Biopharmaceuticals are a class of drugs that are produced from living cells, typically microorganisms or animal cells. However, over the past few decades, scientists have been exploring the use of plants as an alternative source for producing biopharmaceuticals. This is mainly due to the advantages that plant-based systems offer over traditional methods such as animal or microbial cell culture.
One of the primary advantages of using plants is that they are cost-effective, easy to cultivate and maintain, and have the ability to produce complex proteins. Additionally, plants are less likely to carry infectious agents, which makes the production of biopharmaceuticals from plants safer. In this article, we will discuss some of the biopharmaceuticals that have been produced from plants and their applications in modern medicine.
Elelyso: A Treatment for Gaucher Disease
Elelyso is a plant-based biopharmaceutical that is used for the treatment of Gaucher disease, a rare genetic disorder that affects the body’s ability to break down a fatty substance called glucocerebroside. This leads to the accumulation of the substance in various organs, particularly the liver, spleen, and bone marrow. Gaucher disease can cause severe complications such as anemia, easy bruising, and bone fractures.
Elelyso is produced in carrot cells that have been genetically modified to produce a human enzyme called glucocerebrosidase. The enzyme is then extracted and purified, making it ready for use in the treatment of Gaucher disease. Elelyso has been proven to be a safe and effective treatment for Gaucher disease, and it has been approved by the US Food and Drug Administration (FDA) for clinical use.
Zmapp: A Potential Treatment for Ebola Virus

Ebola virus disease is a severe and often deadly illness that is caused by the Ebola virus. Currently, there are no approved treatments or vaccines for Ebola virus disease. However, Zmapp has shown promising results in preclinical trials.
Zmapp is produced in tobacco plants that have been genetically modified to produce monoclonal antibodies that can neutralize the Ebola virus. The antibodies are then harvested and purified, making them ready for use in the treatment of Ebola virus disease. Although Zmapp is still undergoing clinical trials, it has been used in several cases of Ebola virus outbreaks in West Africa and has shown promising results in reducing mortality rates in patients who received the treatment.
Plantibodies: An Alternative to Traditional Antibodies
Plantibodies are a type of biopharmaceutical that are produced from plants. They are similar to traditional antibodies but are produced in plants instead of animal cells. Plantibodies offer several advantages over traditional animal-based antibodies, such as a lower risk of contamination and more accessible production methods.
Plantibodies are produced through genetic modification of plants, in which the plants are engineered to produce a specific antibody. The plants are then grown in controlled environments, and the antibodies are extracted and purified from the plant tissue. Plantibodies are used for a wide range of applications, such as treating cancer, autoimmune diseases, and infectious diseases.
Although the use of plantibodies is still in its early stages of development, it has the potential to revolutionize the way biopharmaceuticals are produced and delivered to patients.
