Courtney Bannerman introduces her PhD research on spinal cord injury, chronic pain, and the nervous system-immune system interactions, which involves a mouse model. She addresses the public's discomfort with animal research, detailing how negative media portrayals, like an article in the Queen's Journal, prompted her to write a response advocating for the scientific necessity and ethical considerations of animal testing. She highlights the general reluctance of animal researchers to speak out due to harassment.
Bannerman explains the stringent legislation for animal research in Canada. Universities and researchers must obtain a certification of good animal practice from the Canadian Animal Care Committee, which undergoes surprise inspections every three years. Each university also has its own Animal Care Committee, comprising diverse members, including researchers, technicians, veterinarians, and community representatives, to approve protocols based on the 'three R's': Reduction, Replacement, and Refinement.
The video discusses impressive advancements in computational modeling, cell, and tissue culturing, and the sharing of large datasets and public databases. These tools help reduce the number of animals needed and refine research focus. However, Bannerman points out their limitations, such as the inability of petri dish cells to replicate organ architecture or inter-organ communication, and the challenge of distinguishing causation from correlation in human data without animal models for functional validation.
Bannerman addresses the ethical dilemma of prioritizing human life over animal life, explaining that science employs a hierarchy of organism sentience to balance clinical relevance and ethical use. She cites examples like Minocycline for MS and the development of insulin, aspirin, and antibiotics, all of which relied heavily on animal research. She argues that while scientists would adopt equally effective non-animal models if available, such models don't yet exist for many diseases.
Bannerman concludes by emphasizing that while animal research is an uncomfortable topic, an informed discussion is crucial. She encourages a nuanced perspective, allowing for support of animal use in biomedical research while questioning its application in other areas like cosmetic research. She reiterates the severity of spinal cord injuries and chronic pain, and how her multimodal approach, including a new mouse model, aims to develop better therapeutics, acknowledging the irreplaceable contributions of laboratory animals.
