Description of Research Expertise

Research Interests
We are interested in the structure and function of virus receptors, with a particular interest in the receptors for coxsackieviruses and adenoviruses.

Key Words: Virus entry, adenovirus, coxsackievirus, viral pathogenesis, virus receptor.

Description of Research
Coxsackieviruses— non-enveloped viruses that cause neurologic and cardiac disease in humans)— interact with at least two receptors during virus infection— CAR (the coxsackievirus and adenovirus receptor), and DAF (CD55, a complement regulatory molecule). On polarized epithelial cells, which are likely the first targets of natural infection, CAR is sequestered in intercellular junctions, and is inaccessible to virus; in contrast, DAF is expressed on the cell surface. We have found that DAF-mediated signals are important for virus infection of polarized cells. We are interested in defining the signaling molecules and other cellular factors required for coxsackievirus infection of polarized cells, and the mechanisms by which other viruses infect these cells. We are studying the cell biology of virus entry, with a focus on understanding the separate roles of the two receptors during the entry process. We have also developed transgenic and conditional knockout systems with which to examine the function of the two receptors during infection in vivo.

We have found that DAF-mediated signals are important for virus infection of polarized cells. We are interested in defining the signaling molecules and other cellular factors required for coxsackievirus infection of polarized cells. We are also interested in the routes by which other DAF-binding viruses enter these cells. In further work, we want to define the structural features of virus-DAF interaction.
