• Research in the Division of Asthma

    Research Overview

    Asthma and allergic diseases are a serious public health burden and affect over 40% of the population worldwide.  In the Division of Asthma Research our overarching goal is to develop new prevention and treatment strategies for allergic diseases that are personalized and target high risk populations at the critical time periods when they are most vulnerable.

    Research Focus

    In the Division of Asthma Research we are focused on understanding the total exposure relevant to asthma from the cell and individual level to the patient, family neighborhood and community level.  We aim to identify the factors that contribute to asthma development and symptoms, determine the mechanisms by which these factors contribute to disease, delineate how effects of environmental exposure are modified by genetics and other exposures, and identify biomarkers of exposure and disease activity and severity in an individual.   Our current projects include a spectrum of basic, translational and clinical research that investigates the role of these factor in promoting disease development and activity.

    The division utilizes transdisciplinary approaches integrating human cohorts, in vitro systems, and animal models to address these complex problems.  Numerous other factors affect disease outcomes as well including psychosocial factors, community health perceptions, and health literacy.

  • Heterogeneity in Asthma in a statewide collaborative: The Ohio Pediatric Asthma Repository

    Asthma heterogeneity causes difficulty in studying and treating the disease.  In this study we built a comprehensive statewide repository linking questionnaire and medical record date with health outcomes to characterize the variability of clinical practices at Ohio children’s hospitals for the treatment of hospitalized asthma.

  • Exposure to allergen and DEP potentiates secondary allergen-specific memory responses, promoting asthma susceptibility

    Exposures to traffic pollution particulate matter, predominantly diesel particles (DEPs), increase the risk of asthma and asthma exacerbation: however, the underlying mechanisms remain poorly understood.  In this study we sought to examine the effect of DEP exposure on the generation and persistence of allergen-specific memory T cells in asthmatic patients and translate these findings by determining the effect of early DEP exposure on the prevalence of allergic asthma in children.
