Supporting Cutting Edge Research at UNCAnimal models are often used in the biomedical field as a proxy for working with humans. Small animals, such as mice, are widely used as mammalian model systems because of the similarities in genetics and physiology with humans. These model systems also have the advantage of being easily manipulated genetically allowing researchers the ability to interrogate the role of specific genes in a number of biological processes, including host-pathogen interactions with infectious agents like, HIV, cancers and inflammatory diseases.
While researchers have learned much about disease pathogenesis using mouse model systems, there are limitations to using these surrogates to investigate the intricate interactions between humans and infectious diseases. Notably, differences in the immune systems between mice and humans complicate their use for many human pathogens that are species-specific and can only infect human cells. One powerful approach to circumvent this restriction is the development of “humanized” mice in which the mouse immune system is effectively replaced by human cells through implantation or more recently, genetic manipulation. Mice that are reconstituted with human cells offer a unique model for studying infectious disease pathogenesis, transmission, and persistence in vivo and are now widely used in the biomedical field for studying diseases such as HIV.
In ground-breaking research at UNC, Dr. J. Victor Garcia-Martinez and colleagues have been working on expanding the animal model toolkit available to pre-clinical researchers by developing a novel mouse model system which would allow researchers to better understand the function of the immune system and its role in mediating protection against infectious diseases. In support of this cutting-edge research, the Biological Safety Section in the Department of Environment, Health & Safety worked closely with Dr. Garcia-Martinez to assess the biological risks associated with working with macaque primate tissue, and establish standard operating procedures and containment practices for working safely with this potentially biohazardous model thus paving the way to approval of this research by the Institutional Biosafety Committee (IBC).
