Goals / Objectives
The UCD Davis Center for Comparative Medicine stands poised to make its contribution to research on persistent viral/chronic viral diseases. All of the elements are in the place: 1) funding a research building has been obtained and design is in progress; 2) binding commitments of support from the University, the campus and the two School are in hand; an innovative, collaborative research plan is in place; a growing area of concern in human health has been designated as the Center's focus; 4) unique educational and animal model resources are co-located at UC Davis; and 5) faculty, with proven track records, are united in their interest.
Project Methods
The gene therapy scientis will develop and optimize gene transfer methodologies for whole animals based on direct DNA injection and encapsulation of DNA into liposomes. Specific therapeutic modalities include delivery of transdominant mutants of essential viral genes to block viral replication and delivery of cytokine genes to augment host antiviral defenses. In addition, gene transfer vectors expressing viral antigens can be used to immunize and elicit antiviral host immune responses. The antiviral drugs scientist will integrate research in animal model systems with methods in cell and molecular biology, biochemistry and pharmocology. Major targets are retroviral infections; to this end, novel therapeutic approaches will be aimed at SIV in monkeys and FIV in cats. Importantly, mechanisms of resistance to antiviral drugs will be investigated, and alterations in pathogenic properties of resistant viruses will be evaluated in animal models. The biological response modifers scientist will investigate the roles of various cytokines in antiviral immune responses and in mechanisms of viral pathogenesis in animal modes. One objective is to identify an immunization protocol that combines a specific cytokine(s) with viral antigens for eliciting protective immunity. By modulating levels of specific cytokines in infected animals, it may be possible to prevent or minimize cell and tissue dysfunction due to viral infection.

Progress 01/15/96 to 01/14/05

Outputs
The UC Davis Center for Comparative Medicine (CCM) is a cooperative, interdisciplinary research center co-sponsored by the Schools of Medicine and Veterinary Medicine. The CCM research mission is to investigate host-agent interactions and develop intervention strategies for persistent infectious diseases common to humans and animals. Society faces immediate problems in regard to persistent infectious diseases, which are becoming more urgent as world population grows, people are living longer and infectious and zoonotic diseases are emerging at an increasing rate. It has been decided that, in the future, each individual project will be reported separately to CRIS, rather than have one 'blanket' or 'umbrella' project to cover this Center. CALV-MARKEY-96-15, therefore, is being terminated at this time.

Impacts
Persistent infections/diseases, including viral (e.g. acquired immune deficiency syndrome virus, cytomegalovirus, papilloma viruses, etc.), bacterial (e.g. Lyme disease, ehrlichiosis, tuberculosis, etc.), and parasitic (e.g. malaria, babesiosis, metazoan parasitism, etc.) are shared by both humans and animals or induced by closely related agents in humans and animals. Investigation of these diseases, which have enormous impact on society, will benefit both humans and animals.

Progress 01/01/01 to 12/31/01

Outputs
Current CCM-related research involves human, simian and feline immunodeficiency viruses; human, simian, bovine, feline and murine leukemia viruses; human and simian cytomegaloviruses; human and simian papillomaviruses; human and animal Lyme disease; human and animal ehrlichiosis; and murine gene targeting for animal model development. The scope of the research program will expand as CCM faculty recruitment progresses. CCM faculty members possess a broad range of complementary and interdisciplinary expertise that should lead to novel approaches to prevention and therapy of persistent infectious diseases that have proven otherwise refractory to clinical intervention by conventional means. CCM faculty members also provide expertise beyond infectious disease models, including laboratory animal sciences and model development.

Impacts
The primary concept of Comparative Medicine, captured in its name, implies that human and animal diseases share common features that can be exploited to develop strategies toward prevention and therapy. The UC Davis Schools of Medicine and Veterinary Medicine have a rich background of collaborative research into genetic diseases, cancer, organ transplantation, and infectious diseases, and the CCM is the embodiment of this "One Medicine" concept. Another unifying theme of the CCM, persistent infectious diseases common to humans and animals, represents one of the most important problems of our times. CCM research programs thus encompass several principal areas: Host-agent interactions during persistent infections, Mechanisms of oncogenesis by infectious agents, Intervention strategies for prevention and amelioration of persistent infections,

Progress 01/01/00 to 12/31/00

Outputs
The Center for Comparative Medicine (CCM) at the University of California Davis is a collaboration between faculty in the School of Veterinary Medicine, School of Medicine and the California Regional Primate Research Center. The CCM provides a novel environment for research center training in comparative medicine. The primary CCM research mission is the investigation of host-agent interactions during persistent infectious diseases common to humans and animals. The CCM also serves as the academic home for laboratory animal sciences and medicine on campus. A major focus of the CCM mission is research training at the predoctoral, graduate and postdoctoral levels. Over 20 faculty have ongoing research projects at the CCM. Some of the research projects being investigated at the present time include: mouse model of tick- borne Lyme disease and granulocytic ehrlichiosis; tick-borne babesiosis and other protozoan diseases; bartonelloses with an international perspective; transgenic pathology; geonomics; viral oncology; tropical infectious diseases; primate infectious diseases, antiviral strategies in SIV, HIV, FIV, herpes virus and fish diseases, among other projects.

Progress 01/01/98 to 12/31/98

Outputs
Funding for this project and all subsequent activities support the Center for Comparative Medicine at the University of California, Davis. The new Center represents a collaborative effort by faculty members from the medical and veterinary schools and the adjacent California Regional Primate Research Center. In addressing the pathogenesis of persistent viral infections and chronic viral diseases, the Center will emphasize three promising areas: transgenics and the optimization of gene transfer methodologies based on direct DNA injection and encapsulation of DNA into liposomes; development and evaluation of anti-retrovirus drugs; an studies of biological response modifiers, particularly the roles of various cytokines in antiviral immune responses.
