Modulation of virus-cellular receptor interactions in picornaviral pathogenesis

Gastrointestinal viral infections of humans result in a wide variety of illnesses ranging from the common cold to infantile paralysis and viral myocarditis. Despite the wide range of tissues and organs targeted by these viruses, the manner in which infection is initiated is remarkably similar. The primary step in infection is the binding of a virus to a specific protein on the cell surface, similar to the lock and key analogy. This project seeks to investigate the nature of interactions between representative picornaviruses and their cellular attachment proteins with a view to designing rational anti-viral strategies to block virus cell attachment and cell entry. Using the data raised when investigating why some viruses only infect certain cells, we plan to target human tumors cells based on their susceptibilty to different viruses.
