The Eleventh International Foamy Virus Conference took place on 9-10 June 2016 at the Institut Pasteur, Paris, France. The meeting reviewed progress on foamy virus (FV) research, as well as related current topics in retrovirology. FVs are complex retroviruses that are widespread in several animal species. Several research topics on these viruses are relevant to human health: cross-species transmission and viral emergence, vectors for gene therapy, development of antiretroviral drugs, retroviral evolution and its influence on the human genome. In this article, we review the conference presentations on these viruses and highlight the major questions to be answered.
Keywords: FV vectors; cross-species virus transmission; foamy virus; immune responses; latent infection; restriction factors; virus replication; zoonosis.
