Associate Professor, Department of Obstetrics, Gynecology and Reproductive Sciences
Magee Womens Hospital
Dr. Modugno is a molecular epidemiologist focused on women’s cancers, especially ovarian cancer. Ovarian cancer is a highly fatal disease. It is the leading cause of death from a gynecologic malignancy. Over the last thirty years there has been little advancement in understanding the underlying causes of the disease. Beyond bearing children and using oral contraceptives (OCs), few protective factors against the disease have emerged. Moreover, beyond carriage of a mutated BRCA1/2 gene, there are few well-established risk factors for the disease. Through a series of NIH and DOD grants, Dr Modugno’s early work examined the underlying epidemiology of ovarian cancer with a focus on genetic and hormonal factors. Dr Modugno was among the first to show a link between endometriosis and ovarian cancer and that OCs may afford substantial protection for these women, although OC use is less in this population. Although there are several subtypes of ovarian cancer, in general there are no differences in conventional risk factors among the various subtypes. However, pathologically and clinically, we know that the different subtypes have different origins and outcomes. Dr Modugno’s early work began to identify factors differentiating the various subtypes epidemiologically.

Anuradha Ray, PhD
Host Immune Response Focus Group Co-Leader, Center for Medicine and the Microbiome
Professor of Medicine and Immunology
Endowed Professor of Lung Immunology
Dr. Ray has pursued two main areas of research. In one, she has studied immune responses elicited in the airways by allergens and pathogens to understand the immunological and molecular basis of inflammatory diseases like asthma. In the second, she has investigated mechanisms that counter inflammation. Her overall research interest is to elucidate mechanisms of immune tolerance versus inflammation as they relate to pulmonary diseases such as severe asthma as well as host-pathogen interactions in the respiratory mucosa. Early research from her lab led to the identification of NF-κB as a target for glucocorticoid-mediated repression of gene expression and the discovery of GATA-3 as a master regulator of Th2 cells, which promote allergic diseases including asthma. Her laboratory also identified a key role for Tregs expressing membrane-bound TGF-β with cross-talk with the Notch pathway in promoting immune tolerance in the airways. In a study published recently by her group, rather than a dominance of Th2/type 2 immune response, which is commonly associated with asthma, an IFN-γ/Th1 immune bias was detected in more than 50% of severe asthmatics. The heightened Th1 response was shown to inhibit expression of an important protease inhibitor, SLPI, by airway epithelial cells. This study also utilized a newly developed animal model of severe asthma established in her lab, which can be used to test novel therapeutics for severe asthma. In the context of immune tolerance, her recently published study has identified an important role of mitochondrial metabolism in lung dendritic cells in the maintenance of immune tolerance in the airways. Studies in her lab are conducted using animal models of disease and human samples, which are analyzed using cutting-edge immunological, molecular, biochemical, physiological and imaging techniques.
