  • Nicola Heller Lab

    Research in the Nicola Heller Lab focuses on the immunobiology of macrophages. Our team explores how these cells impact diseases with an inflammatory element, such as cancer, cardiovascular disease and obesity. Using a variety of techniques, including molecular and cellular biology, biochemistry, mouse models and more, we study the role of IL-4/IL-13 signaling in asthma and allergic disease, as well as the role of alternatively activated macrophages (AAM) in the pathogenesis of allergic inflammation. Currently, we are researching the links between asthma and obesity, with a focus on the roles of gender and race.
  • Maryam Jahromi Lab

    The Maryam Jahromi Lab researches infectious diseases such as influenza, tuberculosis, endocarditis, viral hemorrhagic fevers, brucellosis, Clostridium difficile and Crimean-Congo hemorrhagic fever. We are particularly interested in the impact of the influenza vaccine on systemic inflammation. Recent areas of focus include the relationship between influenza vaccination and cardiovascular outcomes, the emergence of Crimean-Congo hemorrhagic fever in Iran, and prospects for vaccines and therapies for Crimean-Congo hemorrhagic fever.

  • Cynthia Sears Laboratory

    Work in the Cynthia Sears Laboratory focuses on the bacterial contributions to the development of human colon cancer and the impact of the microbiome on other cancers and the therapy of cancer. The current work involves mouse and human studies to define how enterotoxigenic Bacteroides fragilis, pks+ Escherichia coli, Fusobacterium nucleatum, biofilms and the colonic microbiota induce chronic colonic inflammation and colon cancer. Prospective human studies of the microbiome and biofilms in screening colonoscopy are in progress as are studies to determine if and how the microbiome impacts the response of individuals with cancer to immunotherapy and other cancer therapies.

  • Sean Leng Lab

    The Sean Leng Lab studies the biology of healthy aging. Specific projects focus on chronic inflammation in late-life decline; immunosenescence and its relationship to the basic biological and physiological changes related to aging and frailty in the human immune system; and T-cell repertoire analysis.

  • Pulmonary Infection and Inflammation Research Lab

    The Jia lab performs basic and translational research into the mechanisms of and therapeutic strategy for viral and bacterial infection-induced inflammatory lung diseases, one of the leading causes of death in pulmonary diseases, especially for the ongoing pandemic of the SARS-CoV-2 mediated COVID-19. Our work has identified novel roles of Angiotensin-converting enzyme 2 (ACE2) in the inflammatory response to viral and bacterial lung infection and its complex contributions into the pathogenesis and disease progression and outcome of COVID-19. In seeking to translate these findings to clinical studies, we have been working on a collaboration with other investigators, developing novel diagnostic, preventive, and therapeutic tools in combating the devastating COVID-19, even in the era of effective vaccine prevention. These studies are funded by NIAID.

  • Peter Abadir Lab

    Research in the Peter Abadir Lab focuses on the renin-angiotensin system (RAS), a signaling pathway that regulates blood pressure and has been linked independently to both aging and inflammation. We’re particularly interested in changes in RAS that occur with aging. We also study signal transduction and the role of the crosstalk between angiotensin II receptor in aging and are interested in understanding the function of angiotensin II in the process of vascular aging.

  • The Sfanos Lab

    The Sfanos Lab studies the cellular and molecular pathology of prostate disease at the Johns Hopkins University School of Medicine. We are specifically interested in agents that may lead to chronic inflammation in the prostate, such as bacterial infections and prostatic concretions called corpora amylacea. Our ongoing studies are aimed at understanding the influence of prostate infections and inflammation on prostate disease including prostate cancer and benign prostatic hyperplasia (BPH). The laboratory also focuses on the influence of the microbiome on prostate disease development, progression, and/or resistance to therapy.

  • Qian-Li Xue Lab

    The primary area of statistical expertise in the Qian-Li Xue Lab is the development and application of statistical methods for: (1) handling the truncation of information on underlying or unobservable outcomes (e.g., disability) as a result of screening, (2) missing data, including outcome (e.g., frailty) censoring by a competing risk (e.g., mortality) and (3) trajectory analysis of multivariate outcomes. Other areas of methodologic research interests include multivariate, latent variable models. In Women's Health and Aging Studies, we have closely collaborated with scientific investigators on the design and analysis of longitudinal data relating biomarkers of inflammation, hormonal dysregulation and micronutrient deficiencies to the development and progression of frailty and disability, as well as characterizing the natural history of change in cognitive and physical function over time.

  • Mark Liu Lab

    Research in the Mark Liu Lab explores several areas of pulmonary and respiratory medicine. Our studies primarily deal with allergic inflammation, chronic obstructive pulmonary disease (COPD) and asthma, specifically immunologic responses to asthma. We have worked to develop a microfluidic device with integrated ratiometric oxygen sensors to enable long-term control and monitoring of both chronic and cyclical hypoxia. In addition, we conduct research on topics such as the use of magnetic resonance angiography in evaluating intracranial vascular lesions and tumors as well as treatment of osteoporosis by deep sea water through bone regeneration.
