Summary
Paul R. Bohjanen, MD, PhD, and has been a faculty member in the Division of Infectious Diseases and International Medicine since 2000. He graduated from the University of Michigan with an MD, PhD degree in 1993. He then completed an internal medicine residency in 1997 and an infectious diseases fellowship in 2000, both at Duke University. Dr. Bohjanen has a clinical interest in HIV infection and the global AIDS epidemic. His laboratory research is directed at understanding the regulation of gene expression in T cells in normal and HIV-infected humans.
Research Summary
T Lymphocyte mRNA Stability (Access our mRNA Decay Database) Research in my laboratory focuses on the role of mRNA decay in regulating T lymphocyte activation and function. Many genes that are important for cell growth and immune function are turned on at precise times and turned off at precise times. Dysregulated expression of many of these genes, including proto-oncogenes and cytokine genes, occurs in disease states such as cancer, autoimmunity, or immunodeficiency. One mechanism that cells use to turn off gene expression is specific degradation of mRNA within the cytoplasm. We have recently shown that the rate of decay of many transcripts encoding important regulatory proteins changes upon cellular activation, and these changes in mRNA decay can have dramatic effects on overall gene expression. Our goal is to understand the biochemical mechanisms that regulate mRNA decay and to understand the role of mRNA decay in regulating gene expression in disease states such as malignancy or virus infection. HIV Immune Reconstitution Inflammatory Syndrome We are applying our expertise in immune cell gene expression and microarray technology to HIV immune reconstitution inflammatory syndrome (IRIS), an important complication of antiretroviral therapy (ART) that has recently emerged in Africa. (IRIS) is a paradoxical inflammatory response that occurs after initiating HIV antiretroviral therapy (ART). Common IRIS scenarios include the "unmasking" of an occult opportunistic infection or the "paradoxical" symptomatic worsening of a prior infection despite microbiologic treatment success. We have developed a collaborative project with the Infectious Diseases Institute at Makerere University in Kampala, Uganda to prospectively follow HIV-infected patients in Uganda after they initiate antiretroviral therapy and to compare immune activation using microarrays, cytokine profiling, and flow cytometry in patients that do or do not develop IRIS. These studies will identify biomarkers that can be used to diagnose, predict, or monitor IRIS and will provide insight into the pathophysiology of IRIS that will allow the development of better treatments.

Summary
Dr. Boulware is an infectious disease physician-scientist with formal training in clinical trials, public health, and tropical medicine. Dr. Boulware combines his clinical research with nested basic science investigations into disease pathogenesis to conduct translational research. His primary research interests are in meningitis in resource-limited areas including diagnosis, prevention, treatment, and quality improvement initiatives incorporating cost-effectiveness analyses in order to translate knowledge into improved care. Dr. Boulware's current research is focused on improving the clinical outcomes of HIV-infected persons with cryptococcal meningitis, the second most common AIDS-defining opportunistic infection in Sub-Saharan Africa and the most common cause of adult meningitis. Additionally, Dr. Boulware has been motivated to improve the diagnostics for TB meningitis, and now that TB meningitis can be promptly diagnosed, to also improve the treatment of tuberculous meningitis. Dr. Boulware leads a multidisciplinary, international research team with active research collaborations with partners in Uganda, South Africa, Ethiopia, Brazil, Botswana, the Netherlands, and the United Kingdom.

Dr. Chan-Colenbrander received her medical degree from Western University (University of Western Ontario), Canada. She completed her Internal Medicine residency at University of Minnesota and Infectious Disease fellowship at Vanderbilt University. Prior to her medical training, she graduated with a Bachelor of Science (hon), majoring in Microbiology at National University of Malaysia and later received her Master of Medical Sciences degree at University of Malaya. Her research was on the application of PCR in the rapid diagnosis of dengue virus infection. Previous research experiences include antibiotic resistance, prevention of hospital infections and interactions among the anti-retroviral drugs mediated by cellular drug transporters. Since her ID fellowship, she has been working as an Internal medicine and Infectious diseases physician in various healthcare settings. This experience has provided her with a good insight on how to provide good care, manage and prevent infections and diseases. My focus is on good patient care, learning and sharing of knowledge.
