Viruses pose a constant danger to living organisms. An astounding variety of viruses are recognized as human pathogens. The roster lengthens as humans come into more intimate contact with animal reservoirs harboring novel viruses and new technologies reveal human viruses that have previously escaped detection.
The vertebrate immune system evolved in response to the threat posed by viruses. The importance of the immune system in protecting against lethal viral infections becomes obvious in innate or acquired immunodeficiencies, where depression of one or more elements of the system results in death from a typically "self-limited" viral infection, or in the success of vaccines in preventing dangerous viral infections. The immune system (like every biological system) is not perfect, and overzealous anti-viral responses frequently contribute to viral diseases.
The mission of our laboratory is to extend basic understanding of the interaction between the immune system and viruses using mouse infection models. Ongoing projects include the following:
- Real-time imaging of virus-host interactions using multiphoton microscopy with the immediate goal of rational design of vaccines for inducing CD8+ T-cell responses
- Unraveling the role of the sympathetic nervous system in adaptive immune responses
- Understanding the generation of MHC class I peptide ligands from endogenous and exogenous viral antigens
- Defining mechanisms that contribute to antigenic drift in the influenza A virus hemagglutinin
- Understanding how PB1-F2, the 11th defined influenza A virus gene product, modulates host immunity
