  • Andrea Cox Lab

    Principal Investigator:
    Andrea Cox, M.D., Ph.D.
    Medicine

    Research in the Andrea Cox Lab explores the immune response in chronic viral infections, with a... focus on HIV and the hepatitis C virus (HCV). In our studies, we examine the role of the immune response upon exposure to HCV by examining responses to HCV in a longitudinal, prospective group of high-risk individuals. This enables us to compare the innate, humoral and cellular immune responses to infection with clearance versus persistence. Through our findings, we seek to identify mechanisms of protective immunity against HCV infection and improve HCV vaccine design. view more

  • Balagopal Lab - Viral Hepatitis and Translational Virology

    Principal Investigator:
    Ashwin Balagopal, M.D.
    Medicine

    The Balagopal Lab has adapted high-resolution tools to study viruses in situ. Specifically, we ...were the first to quantify hepatitis C virus (HCV) infection in single hepatocytes by developing single-cell laser capture microdissection (scLCM) and integrating this tool with highly sensitive quantitative real-time PCR. We reported that HCV infects a minority of hepatocytes that are found in geospatial clusters. More recently, we (PIs Balagopal and Thio) integrated scLCM with droplet digital PCR (ddPCR) to reveal the first observations of hepatitis B virus (HBV) infection at single cell resolution in the liver. We found that HBV infects nearly all hepatocytes prior to antiviral therapy. However, during antiviral therapy, HBV infection is diminished while viral transcription is markedly attenuated.

    Our lab has also focused on HIV-1 infection and immune activation for over a decade. Most recently, we have studied type 1 interferon responses to HIV-1 using RNA sequencing (RNAseq). Using this technology, we identified novel interferon-stimulated genes (ISGs) that are associated with HIV-1 restriction in vivo.

  • Charles W. Flexner Laboratory

    Principal Investigator:
    Charles Flexner, M.D.
    Medicine

    A. Laboratory activities include the use of accelerator mass spectrometry (AMS) techniques to m...easure intracellular drugs and drugs metabolites. AMS is a highly sensitive method for detecting tracer amounts of radio-labeled molecules in cells, tissues, and body fluids. We have been able to measure intracellular zidovudine triphosphate (the active anabolite of zidovudine) in peripheral blood mononuclear cells from healthy volunteers given small doses of 14C-zidovudine, and have directly compared the sensitivity of AMS to traditional LC/MS methods carried out in our laboratory.

    B. Clinical research activities investigate the clinical pharmacology of new anti-HIV therapies and drug combinations. Specific drug classes studied include HIV reverse transcriptase inhibitors, protease inhibitors, entry inhibitors (selective CCR5 and CXCR4 antagonists), and integrase inhibitors. Scientific objectives of clinical studies include characterization of early drug activity, toxicity, and pharmacokinetics. Additional objectives are characterization of pathways of drug metabolism, and identification of clinically significant harmful and beneficial drug interactions mediated by hepatic and intestinal cytochrome P450 isoforms.

  • Christian Merlo Lab

    Principal Investigator:
    Christian Merlo, M.D., M.P.H.
    Medicine

    Work in the Christian Merlo Lab includes studies on pulmonary arteriovenous malformations, outc...omes in lung transplantation and treatment of cystic fibrosis (CF), and HIV-related pulmonary disease. We have studied methods of diagnosing and managing pulmonary arteriovenous malformations as well as the outcomes of adult CF patients who are infected with multiple antibiotic-resistant Pseudomonas aeruginosa. Our recent research has also explored recipient and donor variables in the success or failure of lung transplants, and ways in which national healthcare delivery systems impact lung transplant outcomes for CF patients. view more

    Christine Durand, M.D.
    Medicine

    Dr. Christine Durand, assistant professor of medicine and oncology and member of the Johns Hopk...ins Kimmel Cancer Center, is involved in clinical and translational research focused on individuals infected with HIV and hepatitis C virus who require cancer and transplant therapies. Her current research efforts include looking at outcomes of hepatitis C treatment after solid organ transplant, the potential use of organs from HIV-infected donors for HIV-infected solid organ transplant candidates, and HIV cure strategies including bone marrow transplantation.

    Dr. Durand is supported by multiple grants:

    • R01 from the National Institute of Allergy and Infectious Diseases (NIAID) to study HIV-to-HIV organ transplantation in the US.
    • K23 from the National Cancer Institute (NCI) to study antiretroviral therapy during bone marrow transplant in HIV-1 infection.
    • U01 from the NIAID to study HIV-to-HIV deceased donor kidney transplantation.
    U01 from the NIAID to study HIV-to-HIV deceased donor liver transplantation.

  • Gregory Kirk Lab

    Research in the Gregory Kirk Lab examines the natural history of viral infections — particularl...y HIV and hepatitis viruses — in the U.S. and globally. As part of the ALIVE (AIDS Linked to the Intravenous Experience) study, our research looks at a range of pathogenetic, clinical behavioral issues, with a special focus on non-AIDS-related outcomes of HIV, including cancer and liver and lung diseases. We use imaging and clinical, genetic, epigenetic and proteomic methods to identify and learn more about people at greatest risk for clinically relevant outcomes from HIV, hepatitis B and hepatitis C infections. Our long-term goal is to translate our findings into targeted interventions that help reduce the disease burden of these infections. view more

  • Haughey Lab: Neurodegenerative and Neuroinfectious Disease

    Lab Website
    Principal Investigator:
    Norman Haughey, Ph.D.
    Neurology
    Neurosurgery

    Dr. Haughey directs a disease-oriented research program that address questions in basic neurobi...ology, and clinical neurology. The primary research interests of the laboratory are:

    1. To identify biomarkers markers for neurodegenerative diseases including HIV-Associated Neurocognitive Disorders, Multiple Sclerosis, and Alzheimer’s disease. In these studies, blood and cerebral spinal fluid samples obtained from ongoing clinical studies are analyzed for metabolic profiles through a variety of biochemical, mass spectrometry and bioinformatic techniques. These biomarkers can then be used in the diagnosis of disease, as prognostic indicators to predict disease trajectory, or as surrogate markers to track the effectiveness of disease modifying interventions.
    2. To better understand how the lipid components of neuronal, and glial membranes interact with proteins to regulate signal transduction associated with differentiation, motility, inflammatory signaling, survival, and neuronal excitability.
    3. To understand how extracellular vesicles (exosomes) released from brain resident cells regulate neuronal excitability, neural network activity, and peripheral immune responses to central nervous system damage and infections.
    4. To develop small molecule therapeutics that regulate lipid metabolism as a neuroprotective and restorative strategy for neurodegenerative conditions.
