The Viruses and Cells Gordon Conference is a premier meeting in the field of Virology, emphasizing the dynamic interaction between viruses and the cells and organisms they infect. The 2005 meeting will be held at Il Ciocco, Barga, Italy May 15-20. This conference is designed to be a highly interactive meeting that encompasses a broad view of the field of virology. Invited speakers and discussion leaders will present recent ground-breaking findings on the mechanisms of viral structure, replication, and pathogenesis, as well as mechanisms involved in the host antiviral and immune responses to infection. The most recent developments also are featured by selecting several talks from abstracts submitted at the time of registration and through the use of prominently featured poster sessions. Participants will include a mixture of investigators from academia, government and industry, graduate students and postdoctoral fellows.
