Robinson Lab

The research lab of Christopher M. Robinson, PhD focuses on the complex methods in which enteric viruses traverse the intestinal environment to initiate infection. The laboratory specifically identifies intestinal factors that influence viral replication.

Enteric viruses initiate infection in the diverse environment of the gastrointestinal tract, yet the impact of this environment on intestinal infection is unclear. By characterizing intestinal factors that alter enteric viral virulence, potential therapeutic targets may be identified.

Sex-dependent Replication of Coxsackievirus

Using coxsackievirus– a model enteric virus– the Robinson Lab studies how biological sex can influence viral replication in the intestine. By using an oral-inoculated mouse model the lab found that, similar to humans, male mice succumb to coxsackievirus-induced disease, whereas females do not. Additionally, coxsackievirus replication in the intestine of male mice is enhanced and may be regulated by sex hormones. The Robinson Lab current focuses on using in vitro and in vivo approaches to determine the mechanism behind sex-dependent replication and pathogenesis of coxsackievirus.

Intestinal Bacteria

The intestine is home to a large community of bacteria that are vital for human health. Emerging data suggest that intestinal bacteria enhance replication and pathogenesis of enteric viruses, yet the mechanism of these interactions remain unclear. The Robinson Lab is interested in understanding the mechanisms and consequences of the interactions between intestinal bacteria and enteric viruses using coxsackievirus and other picornaviruses as a model.
