Dr. Bose is currently a faculty member in the Washington State University College of Veterinary Medicine. Before moving to Washington State in 2014, Dr. Bose was a faculty member of the Department of Microbiology and Immunology in the University of Texas Health Science Center Medical School. His research is focused on understanding innate immune response against respiratory viruses like influenza A virus, human respiratory syncytial virus, parainfluenza viruses, and more recently coronaviruses, including SARS-CoV-2 (COVID-19). Particularly he is interested in elucidating the mechanisms regulating innate antiviral and inflammatory response, which play a critical role in host defense against respiratory viruses and development of hyper-inflammatory airway diseases like pneumonia. These studies are also geared to development of viral therapeutics to control virus-associated airway diseases like pneumonia.

Mechanisms regulating inflammation during respiratory virus infection
Chronic and acute inflammation is involved in pathogenesis of various inflammatory diseases like arthritis, cancer, atherosclerosis, septicemia, diabetes. Inflammation is also responsible for causing severe lung diseases like pneumonia and bronchiolitis following infection with respiratory viruses including influenza A virus (flu), human respiratory syncytial virus (RSV), parainfluenza viruses and COVID-19 causing coronavirus SARS-CoV-2. In that regard, by utilizing cellular and mice models we are studying the cellular and molecular mechanisms regulating inflammation during flu, RSV, parainfluenza virus and coronavirus (SARS-CoV-2) infection. Knowledge derived from such studies are important for uncovering the basic mechanisms that regulate inflammatory response during disease states and for development of host-based therapeutics to combat airway inflammatory disease like pneumonia. The goal is to develop broad-spectrum host-based therapeutics that can be utilized to combat cross-species deadly pandemic strains of flu and coronavirus infections.

Cellular defense mechanism during respiratory virus infection: role of antiviral innate immunity
We are studying the innate immune antiviral response against respiratory viruses including flu, RSV, parainfluenza virus and coronavirus (SARS-CoV-2). Our study focuses on dissecting the host defense mechanism that is involved in launching an innate response constituting of induction of antiviral pathways in the immune cells like macrophages, lung epithelial cells and respiratory tract. In summary, our laboratory encompasses several aspects of cellular and molecular biology/virology with emphasis on -

  1. Innate immune antiviral signal transduction pathway,
  2. Cellular and molecular mechanism that triggers and regulate inflammation, and
  3. Respiratory virus-host/cell interaction.
