Major Areas of Research

  • Eosinophils, eosinophil ribonucleases, and their role in innate immune responses
  • Inflammatory responses to and novel immunomodulatory therapies for severe respiratory virus infection
  • Diversity and biology of eosinophil and other RNase A family ribonucleases
 

Program Description

The Inflammation Immunobiology Section aims to explore the link between inflammation and infectious disease, specifically, the unique inflammatory sequelae elicited by respiratory virus pathogens. Our laboratory utilizes molecular, cellular, bioinformatics, and in vivo approaches to elucidate novel pathways and to gain insight into critical interactions.

One primary focus of the laboratory program is the eosinophil, an enigmatic leukocyte whose role in innate immunity remains a subject of controversy. Eosinophils are perhaps best known for their contributions to the functional pathophysiology of allergic asthma; however, evolution tells us that the ability to induce pathology cannot be a raison d’être for any existing cell lineage. As such, several distinct lines of evidence have led Dr. Rosenberg's group to consider the possibility that eosinophils and their unique eosinophil secretory ribonucleases may have unrecognized interactions with asthma-exacerbating factors, most notably respiratory virus pathogens.

In conjunction with the aforementioned studies, Dr. Rosenberg's lab has developed a novel mouse model of respiratory viral infection using the natural rodent pneumovirus pathogen, pneumonia virus of mice (PVM). PVM undergoes robust replication in inbred mouse models, and reproduces many of the clinical and pathologic features of the more severe forms of RSV infection in human infants. With this model, Dr. Rosenberg’s laboratory is conducting studies aimed at elucidating novel inflammatory pathways and original immunomodulatory therapies.

Biography

Dr. Rosenberg was awarded both M.D. and Ph.D. degrees from The Rockefeller University and Cornell University Medical College (1984, 1985). Following postdoctoral research at Harvard University, she joined the National Institutes of Health in 1991 and became a section chief in 2002.
