My research explores the use of biomakers in the synovial fluid of the tibiotarsal joint to determine the severity of osteoarthritis (OA) in the distal intertarsal (DIT) and tarsometatarsal (TMT) joints of horses. Currently, the most accurate method of identifying OA in these joints is a combination of thorough physical, lameness, and radiographic examinations. Molecular biomarkers of OA reflect quantitative and dynamic variations associated with joint metabolism. The specific aims are to: (1) define the direct and indirect biomarker concentrations in synovial fluid, and (2) validate/refute that the biomarker concentrations in these joints increase with severity of OA in the distal joints.

Our lab is interested in the gene CD38 and its role in the pathogenesis of asthma. Previous studies from our lab showed that it is playing a role in hyper-responsiveness and inflammation, two of the cardinal features of asthma. Further it was shown that TNF-alpha induced CD38 expression is transcriptionally regulated by transcription factors NFK-B and AP-1 through MAPK pathway. My aims are to determine whether CD38 has a role in remodeling of airways, another feature of asthma and to find out whether CD38 is post-transcriptionally regulated by microRNAs.

My research is focused on creating Bayesian epidemiologic models to describe the within-herd transmission of swine Influenza A virus (IAV) with various conditions of the swine production system. The epidemiological model can serve as a tool to bridge unconnected pieces of information obtained from several places in order to provide insights into the underlying process of the IAV transmission. With the goal of developing an effective IAV surveillance scheme, Bayesian epidemiological models are proposed to describe and predict the IVA transmission within the swine herd conditional to piglet production batching, gilt replacement, and vaccination programs.

Swine Dysentery, caused by Brachyspira hyodysenteriae is a mucohemorragic diarrheal disease of grower-finisher pigs, responsible for significant economic losses globally. In addition, B. pilosicoli causes porcine intestinal spirochetosis, a chronic muco-diarrheal disease, and “B. hampsonii” causes a mucohemorrhagic diarrheal disease which is clinically indistinguishable from Swine Dysentery. Largely disappearing from the U.S. in the late 1980s, the disease has re-emerged across U.S. swine herds during the late 2000s. Broadly, I am interested in developing and implementing techniques useful in the diagnosis, prevention, control and treatment of porcine Brachyspira infections. My research involves validation of antimicrobial susceptibility testing techniques, their implementation for studying antimicrobial susceptibility patterns and investigation of potential resistance mechanisms of Brachyspira species. In addition, it involves molecular genotyping, phylogenetic analyses and molecular epidemiological studies to help elucidate the diversity, distribution, dissemination and potential evolutionary patterns of these pathogens. I am also interested in identifying potential virulence-associated genes/factors for B. hyodysenteriae and “B. hampsonii”, and their role in the pathogenesis of this disease.

The mucosal surfaces are critical sites of transmission of both HIV & simian immunodeficiency virus (SIV). I believe that the ability of a vaccine to induce mucosal immunity is important in order to prevent or reduce the dissemination of HIV and SIV by providing a first line of defense. Using the SIV-infected rhesus macaque as a model for HIV infection, my research focuses on evaluating the ability of CD8 T cell-vaccines to induce high levels of functional SIV-specific CD8 T cells in genital, rectal & lymphoid tissue. I am determining the localization, abundance, and phenotype of SIV-specific CD8 T cells in situ in genital, rectal & lymphoid tissue of vaccinated and control animals.

My research interests focus on the epidemiology of urolithiasis in domestic animals. As a team we have worked on the epidemiology of urolithiasis in dogs, cats and ferrets. Now we are working on the epidemiology of urolithiasis in goats. We plan to extend this study to sheep, cows, horses, pigs, rabbits and guinea pigs. Knowledge of these risk factors may facilitate development of surveillance strategies that result in earlier detection of urolithiasis in domestic animals as well as help in the design of effective diagnostic, therapeutic and prevention of this condition.

I am studying pathogenesis and immunology of reovirus arthritis in turkeys. The virus has been isolated from tendons of 15 weeks old tom turkeys with lameness and ruptured tendons in 2011. We experimentally could reproduce the disease in turkeys. The virus induced tenosynovitis in gastrocnemius tendon sheath at 4 weeks post inoculation with no lameness. Lameness started in experimentally infected birds at 7 weeks post inoculation and % of lameness increased at 15 weeks post inoculation with tendon rupture in some turkeys. Further work is going on to study the pathogenesis of the virus and tissue spread using S4 gene copy number determination by rRT-PCR and immunohistochemisrty. Cytokine profile will be studied also in the infected birds. In addition, gastrocnemius tendon biomechanics will be evaluated in infected birds and electron microscopy will be used to report ultra structural changes in infected birds' tendons.

A correlation between the gray coat color and melanoma development has long been recognized with up to 80% of gray horses older than 15 years developing melanoma. Both graying and melanoma formation have been linked to a duplication in the Syntaxin 17 (STX17) gene, with the STX17 genotype affecting melanoma grade and severity in the Lipizzaner breed. An ASIP mutation, responsible for the bay/black coat color modifies melanoma risk in gray horses, with increased melanoma severity potentially due to an increase in MC1R pathway signaling. We have identified a population of gray Quarter Horses (QH) that appear to have a decreased melanoma risk. The objective of our study is to determine if the decreased incidence of melanoma in gray QH is related to decreased MC1R signaling resulting from the MC1R chestnut coat color allele. Identification of genetic factors that result in altered melanoma susceptibility will allow for more accurate assessment of prognosis and metastasis risk in horses with dermal melanomas.

My research focus is on the epidemiology of PRRS virus in swine herds with an interest in risk factors of infection including spatial and temporal analysis and mapping. We have worked to develop a database of 10 production companies, of approximately 300 sow herds, representing nearly 1,000,000 sows in 14 states. Using this database, we have designed field trials to understand the effect of PRRS vaccination on the frequency and variety of PRRS viruses detected in air within a region. I have also conducted several trials on the role of oral vitamin D3 supplementation in suckling and post-weaned pigs and the response in performance and immune function.

Osteosarcoma is the most common primary bone malignancy affecting children, adolescents and young adults. Additionally, osteosarcoma is commonly found in canines, with approximately 10,000 new cases each year. The complex biology of osteosarcoma and tumor heterogeneity makes it challenging to identify effective new gene targets and therapeutic agents. We have found that a unifying feature of osteosarcoma is the overexpression of miR-17-92 microRNAs. We have deciphered that deregulation of 14q32miR/cMYC network leads to overexpression of miR-17-92 in osteosarcoma. This deregulation is associated with poorer outcomes in osteosarcoma and is preserved in naturally occurring canine osteosarcoma suggesting a conserved disease mechanism. Upregulation of miR-17-92 miRNAs contributes to osteosarcoma progression by targeting potential tumor suppressor osteosarcoma driver genes such as PTEN. Additionally, our studies show that the prodrug Minnelide inhibits cMYC expression and downregulates miR-17-92 miRNAs. Together, our data suggests that upregulation of miR-17-92 miRNAs contributes to osteosarcoma progression and Minnelide reduces tumor burden in osteosarcoma by inhibiting miR-17-92 expression.

Alteration in gut microbiome has been shown to contribute to bowel dysfunction and gut barrier disruption. We have recently demonstrated that morphine treatment results in significant disruption in gut barrier function leading to increased translocation of gut commensal bacteria. Gut microbiome plays an important role in maintaining gut homeostasis. However, the effect of morphine on gut microbiome has not been investigated. Citrobacter rodentium is a natural mouse pathogen that models intestinal infection by enteropathogenic Escherichia coli (EPEC) and enterohemorrhagic E. coli (EHEC) in humans and causes attaching and effacing (A/E) lesions and colonic hyperplasia. My research focuses on the effects of morphine treatment on host mucosal immunity, gut microbiota, and bacterial virulence in a Citrobacter rodentium-mouse model. My research will expand understanding of effects of morphine on the microbiome-neuroimmune axis, and of its role in the gut homeostasis.
