Wendy Beauvais, BVetMed, MSc (VetEpi), PhD

Assistant Professor of Epidemiology and Public Health

Research Information:

Dr. Wendy Beauvais is a veterinary epidemiologist with methodological strengths in analytic epidemiology (including study design, data collection, data analysis), and exploratory and predictive epidemiology (including mathematical modelling and risk assessment). I am motivated by developing new methodological approaches to global sustainability challenges, particularly: meeting global demands for safe food, controlling zoonotic diseases, combatting antimicrobial resistance, and protecting endangered wildlife. A common theme in my research is dealing with different types of uncertainty, including epistemic uncertainties (lack of knowledge), stochasticity (inherent randomness) and natural variation (often by time and space). I am particularly excited about using simulation tools to synthesize evidence and inform decision-making.

Christoph Konradt, PhD

Assistant Professor of Immunology

Research Information:

Research Focus 1: The role of EC in the immune response

There are more than 10 trillion EC in the human body, that cover 4000 m2, and these are an important replicative niche for a subset of micro-organisms such as Dengue virus, West Nile Virus, CMV, S. aureus and T. gondii. For many micro-organisms the ability to infect EC is a key part of their pathogenesis. Indeed, EC express TLR and influence coagulation and neutrophil recruitment and their activation can lead to vascular damage, while expression of adhesion molecules promotes extravasation of inflammatory cells. Numerous in vitro studies have demonstrated that EC can be activated by cytokines to limit viral, bacterial and parasite replication. Furthermore, evidence that EC interact with the adaptive response is implicit in the ability of EC to present MHC class I & II restricted antigens. However, whether EC antigen presentation via MHC-I or MHC-II has a tolerogenic or inflammatory role during infection remains unclear. Therefore, there is a major knowledge gap in our understanding in the involvement of EC in orchestrating a T cell response or how the immune system reacts to infected EC in vivo.

Research Focus 2: Immune responses at the Maternal-Fetal Interface

The maternal-fetal interface is the interface between the uterine mucosa and the extraembryonic tissues of the developing conceptus. The placenta functions as the primary nutrient and gas exchange organ of the fetus by diverting maternal blood flow from the uterus. Once inside the placenta, maternal blood exchanges nutrients, gases, and metabolic waste products with fetal blood coursing through a physically separate vasculature that connects to the fetus via the umbilical cord. A successful pregnancy involves complex interactions between fetal trophoblasts, endothelial cells and maternal decidual immune cells, creating an immunologically unique site that allows the tolerance to the allogenic fetus but still maintains host defense against possible pathogens. Infections are a well-described cause for fetal losses and stillbirths, as well as for perinatal morbidity. Indeed, infections are accounted for up to 15% of early miscarriages and up to 66% of late miscarriages. Moreover, infections can further lead to preterm birth or infants with birth defects leading to lifelong disabilities. This is accompanied with significant health care costs and a burden for the mothers mental health and psychological wellbeing. Immune responses at the maternal-fetal interface during infection are poorly understood and there is a real need for a better understanding of the immunological mechanisms at this site.

Joanne B. Messick, VMD, PhD

Joanne B. Messick, VMD, PhD

PROFESSOR OF VETERINARY CLINICAL PATHOLOGY

Research Information:

Dr. Joanne Messick’s lab focuses on hemotropic mycoplasmas (hemoplasmas), blood-borne bacteria that targets red blood cells of many different mammalian species (cats, dogs, pigs, sheep, alpacas, and others).  The bacteria may cause a primary infection (acute hemolytic anemia) in cats and sheep, while chronic, often asymptomatic infection in pigs and alpacas is the more common presentation.  It’s not clear why these hemoplasmas affect some of the host species differently.  Those differences are a driving force behind the genomics research that Dr. Messick and her graduate students are doing on the bacteria. An additional area of research interest in the Messick lab is exploring the development of red blood cell antioxidant defenses in cats with diabetes. The cat’s cells are extremely sensitivity to damage by these radicals, especially their red blood cells.  By studying the control of gene expression (microRNAs), they hope to identify the weak point(s) in the of the antioxidant mechanisms in feline red blood cells and target it therapeutically to reverse the red cell and systemic effects of free radicals.

Andrea Santos, DVM, MSc, PhD

Andrea Santos, DVM, MSc, PhD

ASSISTANT PROFESSOR OF VETERINARY CLINICAL PATHOLOGY

Research Information:

Dr. Andrea Santos’ research will be focused on the role of microRNAs in the regulation of different cancers and their use as biomarkers for early diagnosis of disease. MicroRNAs are small molecules composed of genetic material and are responsible for the gene regulation in several biological processes in health. These circulating molecules are altered in several diseases making them excellent candidates for biomarker discovery. Many studies in human and animal cancers have shown that these altered microRNAs can be detected in early stages of cancers, increasing the chance of successful treatment. It has been also reported that some microRNAs can be used to predict cancer behavior, as well as to monitor the efficacy of the treatment. Given many similarities between some canine and human cancers, the research will focus on diseases that can use the dog as an animal model for humans.
