The interferon (IFN) response is a major determinant of pathogenesis for many viruses. Not surprisingly, these viruses have evolved many and diverse mechanisms to inhibit the IFN response and its downstream effector molecules (IFN stimulated genes; ISGs). Our goal is to identify and characterize interactions between viruses and host immune molecules that contribute to the development of pathogenesis. In particular, our research is focused on understanding the role of viral RNA structure in virus-host interaction, and how viruses use RNA structure to manipulate cellular pathways.
In particular, our research is focused on understanding how viral RNA functions to modulate these virus-host interactions, and aims to address questions such as:
- How do changes in viral RNA sequence and structure impact virus-host interactions and pathogenesis?
- How do changes in viral RNA impact nucleic acid sensing by the host?
- What is the molecular mechanism(s) of ISGs that impact viral pathogenesis?
- What mechanisms have viruses evolved to circumvent restriction by these host factors?
