  • Andrew Lane Lab

    The Lane laboratory is focused on understanding molecular mechanisms underlying chronic rhinosi...nusitis, particularly the pathogenesis of nasal polyps, as well as inflammation on the olfactory epithelium. Diverse techniques in molecular biology, immunology, and physiology are utilized to study epithelial cell innate immunity, olfactory loss, and response to viral infection. Ongoing work explores how epithelial cells of the sinuses and olfactory mucosa participate in the immune response and contribute to chronic inflammation. The lab creates and employs transgenic mouse models of chronic nasal/sinus inflammation to support research in this area. Collaborations are in place with the School of Public Health to explore mechanisms of anti-viral immunity in influenza and COVID-19. view more

  • Caren L. Freel Meyers Laboratory

    Lab Website

    The long-term goal of the Caren L. Freel Meyers Laboratory is to develop novel approaches to ki...ll human pathogens, including bacterial pathogens and malaria parasites, with the ultimate objective of developing potential therapeutic agents.

    Toward this goal, we are pursuing studies of bacterial isoprenoid biosynthetic enzymes comprising the methylerythritol phosphate (MEP) pathway essential in many human pathogens. Studies focus on understanding mechanism and regulation in the pathway toward the development of selective inhibitors of isoprenoid biosynthesis. Our strategies for creating new anti-infective agents involve interdisciplinary research in the continuum of organic, biological and medicinal chemistry. Molecular biology, protein expression and biochemistry, and synthetic chemistry are key tools for our research.

  • Dong Laboratory

    Principal Investigator:
    Xinzhong Dong, Ph.D.
    Neuroscience

    The Dong Laboratory has identified many genes specifically expressed in primary sensory neurons... in dorsal root ganglia (DRG). Our lab uses multiple approaches, including molecular biology, mouse genetics, mouse behavior and electrophysiology, to study the function of these genes in pain and itch sensation. Other research in the lab examines the molecular mechanism of how skin mast cells sensitize sensory nerves under inflammatory states. view more

  • O'Rourke Lab

    Lab Website
    Principal Investigator:
    Brian O'Rourke, Ph.D.
    Medicine

    The O’Rourke Lab uses an integrated approach to study the biophysics and physiology of cardiac ...cells in normal and diseased states.

    Research in our lab has incorporated mitochondrial energetics, Ca2+ dynamics, and electrophysiology to provide tools for studying how defective function of one component of the cell can lead to catastrophic effects on whole cell and whole organ function. By understanding the links between Ca2+, electrical excitability and energy production, we hope to understand the cellular basis of cardiac arrhythmias, ischemia-reperfusion injury, and sudden death.

    We use state-of-the-art techniques, including single-channel and whole-cell patch clamp, microfluorimetry, conventional and two-photon fluorescence imaging, and molecular biology to study the structure and function of single proteins to the intact muscle. Experimental results are compared with simulations of computational models in order to understand the findings in the context of the system as a whole.

    Ongoing studies in our lab are focused on identifying the specific molecular targets modified by oxidative or ischemic stress and how they affect mitochondrial and whole heart function.

    The motivation for all of the work is to understand
    • how the molecular details of the heart cell work together to maintain function and
    • how the synchronization of the parts can go wrong

    Rational strategies can then be devised to correct dysfunction during the progression of disease through a comprehensive understanding of basic mechanisms.

    Brian O’Rourke, PhD, is a professor in the Division of Cardiology and Vice Chair of Basic and Translational Research, Department of Medicine, at the Johns Hopkins University.

  • Shanthini Sockanathan Laboratory

    Lab Website

    The Shanthini Sockanathan Laboratory uses the developing spinal cord as our major paradigm to d...efine the mechanisms that maintain an undifferentiated progenitor state and the molecular pathways that trigger their differentiation into neurons and glia. The major focus of the lab is the study of a new family of six-transmembrane proteins (6-TM GDEs) that play key roles in regulating neuronal and glial differentiation in the spinal cord. We recently discovered that the 6-TM GDEs release GPI-anchored proteins from the cell surface through cleavage of the GPI-anchor. This discovery identifies 6-TM GDEs as the first vertebrate membrane bound GPI-cleaving enzymes that work at the cell surface to regulate GPI-anchored protein function. Current work in the lab involves defining how the 6-TM GDEs regulate cellular signaling events that control neuronal and glial differentiation and function, with a major focus on how GDE dysfunction relates to the onset and progression of disease. To solve these questions, we use an integrated approach that includes in vivo models, imaging, molecular biology, biochemistry, developmental biology, genetics and behavior. view more
