Research Interests

Host defense mechanism; antiviral response and inflammation: innate immune antiviral and inflammatory response against respiratory RNA viruses like human respiratory syncytial virus (RSV), and influenza A virus (flu).

Respiratory RNA virus infection and inflammation

Respiratory viruses like RSV, flu cause severe lung disease that manifest as pneumonia and bronchiolitis. These two diseases develop due to massive inflammation in the lung. Therefore, we are investigating the mechanism by which RSV and flu induce inflammation in the lung during infection. Particularly, we are interested in identifying and characterizing cellular factor that regulate inflammation. Our lab is focused on elucidating the mechanism of inflammasome activation by viruses. Inflammasome is an intracellular multi-protein complex involved in initiating inflammation by virtue of controlling production of pro-inflammatory mediators and inducing cell death. Our lab is investigating the biochemical, cellular and molecular mechanism responsible for inflammasome complex formation and activation during infection. Our studies have potential to be developed as therapeutic targets to control inflammation (and associated diseases like pneumonia) during respiratory virus infection.

Innate immune antiviral response against respiratory RNA viruses

We are studying the innate immune response (the first line of defense against pathogens) against RSV and flu. These respiratory viruses are highly pathogenic and cause diseases (pneumonia, bronchiolitis) in children/infants and elderly. We are investigating the mechanism of host derived antiviral immune response to identify novel antiviral molecules/pathways, which could be potentially developed as effective antiviral therapy or used as an immunemodulating adjuvant during vaccination. Our studies on innate immune response constitutes investigation of the role of two signaling pathways, NF-kappa B and interferon-alpa/beta induced JAK/STAT pathways in establishing an antiviral state. The long-term goal of our research is to identify and characterize a) the molecules that play a critical role in activation of these pathways and, b) the antiviral factors that are induced by NF-kappa B and JAK/STAT signaling cascades.

In summary, our laboratory encompasses several aspects of cell and molecular biology/virology with emphasis on
a) innate immune antiviral signal transduction pathway,
b) cellular/molecular mechanism that triggers inflammation during virus infection, and
c) virus-host/cell interaction.
