This proposal represents the continuation of the SNF grant “Host evolutionary genomics of HIV-1 and other retroviruses, 2010-2013”. It aims at understanding the cellular and antiviral function of genes that were identified through integrative genomic analyses that used evolutionary genetics, transcriptome and protein interaction data, and functional screens. Of 21389 human genes, 841 (4%) were identified because of features of positive selection in primates. In half of those genes we also detected evidence of codon-specific selection pressure. Among those genes, only 30 genes/proteins (0.14%) were identified through orthogonal datasets as being upregulated during HIV infection in vivo, and/or plausibly interacting with HIV proteins. When overexpressed, several of the 30 genes associated with a profound reduction of HIV replication in the cotransfected cell. siRNA led to the opposing phenotype for some genes that were constitutively transcribed. In addition to traditional components of the interferon response, we identified genes associated with apoptosis and immunomodulatory networks. Importantly, two genes strongly enhanced viral production.To advance in the understanding of cellular function and role in innate immunity of the identified genes, the current proposal aims to:•Explore the role of the candidate host genes in the regulation of the viral replication cycle. •Study the specificity of candidate host genes against HIV, by exploiting the use of primate orthologs and various lentiviral strains, and other retroviruses.•For confirmed anti(retro)viral genes, we aim at exploring a counteracting role of viral accessory proteins, and mapping the site of interaction of host and virus.•Extend analyses to primary cell systems.•Explore novel models of in vivo analysis of antiviral genes.Thus, this project fulfills the goals of previous research that served to identifying novel factors that limit viral replication; it exploits prior results, tools and datasets created in the framework of Swiss National Science Foundation projects. The current research may lead to better understanding of cellular defense against HIV and other retroviruses. The approach can serve as a model for the study of other major human pathogens.
