Introduction
Monoclonal antibodies (mAbs) have been used as therapeutic agents for the treatment of various diseases for several decades. Traditional monoclonal antibody development involved using mice or rats to produce hybridomas that secrete specific antibodies. However, these antibodies were not fully human, which meant they were not always well-tolerated by the human immune system. In the early 1990s, researchers developed a new method of producing fully human monoclonal antibodies, which has since revolutionized the field of biotechnology.
What are Monoclonal Antibodies?
Monoclonal antibodies are laboratory-produced molecules that can mimic the immune system’s ability to fight off harmful pathogens, such as viruses and bacteria. They are designed to target specific proteins or antigens on the surface of cells. When a monoclonal antibody binds to a target antigen, it can trigger an immune response that can help destroy the targeted cell.
Development of Monoclonal Antibodies
The development of monoclonal antibodies begins by injecting an animal with an antigen. The animal’s immune system responds by producing antibodies specific to the antigen. Researchers then extract the animal’s spleen cells, which produce the desired antibodies. These cells are fused with myeloma cells to create hybridoma cells, which can be cultured to produce large quantities of monoclonal antibodies.
Limitations of Traditional Monoclonal Antibody Development
While traditional monoclonal antibody development has been successful in producing antibodies, there are several limitations to this method. One of the most significant limitations is that the antibodies produced are not fully human. As a result, they may not be well-tolerated by the human immune system, which can lead to adverse side effects. In addition, the use of animals in monoclonal antibody development raises ethical concerns.
Fully Human Monoclonal Antibody Development
Fully human monoclonal antibody development is a method of producing antibodies that are derived entirely from human sources. This method involves using human cells or humanized mouse cells to produce antibodies, which eliminates the risk of immune system rejection compared to traditional monoclonal antibody development. In addition, it reduces the duration of toxicology studies in animal therby decreasing ethical concerns
Advantages of Fully Human Monoclonal Antibodies
There are several advantages to using fully human monoclonal antibodies over traditional monoclonal antibodies. First, fully human antibodies are less likely to be rejected by the human immune system, which reduces the risk of adverse side effects. Second, they can be used in patients with compromised immune systems, such as those undergoing chemotherapy. Finally, fully human antibodies are less likely to cause an immune response, which can reduce the risk of developing resistance to the antibody.
Methods of Fully Human Monoclonal Antibody Development
There are several methods of producing fully human monoclonal antibodies, including:
Phage Display Technology: This method involves using a phage (a type of virus that infects bacteria) to display antibodies on its surface. Researchers can then identify and isolate the specific antibodies that bind to the target antigen.
Hybridoma Technology: This method involves fusing human B cells with myeloma cells to create hybridoma cells that secrete fully human monoclonal antibodies.
Transgenic Mice Technology: This method involves genetically engineering mice to produce fully human antibodies. The mice are then injected with an antigen, and their immune systems respond by producing specific antibodies.
Applications of Fully Human Monoclonal Antibodies
Fully human monoclonal antibodies have a wide range of applications in medicine and biotechnology, including:
Cancer Treatment: Fully human monoclonal antibodies can be used to target and destroy cancer cells.
Autoimmune Diseases: Fully human monoclonal antibodies can be used to target and suppress the immune system, which is overactive in autoimmune diseases.
Infectious Diseases: Fully human monoclonal antibodies can be used to prevent and treat infectious diseases, such as HIV and Ebola.
Neurodegenrative diseases: Fully human antibodies can be used to treat neurodegenerative diseases such as fronto-temporal dementia, Alzheimer or Parkinson diseases.
Challenges in Fully Human Monoclonal Antibody Development
Despite the advantages of fully human monoclonal antibodies, there are several challenges in their development, including:
Production Costs: Fully human monoclonal antibodies are more expensive to produce than traditional monoclonal antibodies.
Limited Potency: Fully human monoclonal antibodies may have limited potency compared to traditional monoclonal antibodies unless the mice have a robust display of human immune repertoire and great immunization such as the one used by Precision Antibody with humanized mice.
Immunogenicity: Fully human monoclonal antibodies may still be immunogenic, meaning they can trigger an immune response in some patients.
Conclusion
Fully human monoclonal antibody development has revolutionized the field of biotechnology and medicine. By using fully human cells to produce antibodies, researchers have been able to develop more effective and better-tolerated therapeutic agents. However, challenges still exist in fully human monoclonal antibody development, and further research is needed to address these challenges.
