1HIV-induced membraneless organelles orchestrate post-nuclear entry steps显示文摘HIV integration occurs in chromatin sites that favor the release of high levels of viral progeny;alternatively, the virus is alsoable to discreetly coexist with the host. The viral infection perturbs the cellular environment inducing the remodelling of thenuclear landscape. Indeed, HIV-1 triggers the nuclear clustering of the host factor CPSF6, but the underlying mechanism ispoorly understood. Our data indicate that HIV usurps a recently discovered biological phenomenon, called liquid–liquid phaseseparation, to hijack the host cell. We observed CPSF6 clusters as part of HIV-induced membraneless organelles (HIV-1 MLOs) inmacrophages, one of the main HIV target cell types. We describe that HIV-1 MLOs follow phase-separation rules and representfunctional biomolecular condensates. We highlight HIV-1 MLOs as hubs of nuclear reverse transcription, while the double-strandedviral DNA, once formed, rapidly migrates outside these structures. Transcription-competent proviruses localize outside but nearHIV-1 MLOs in LEDGF-abundant regions, known to be active chromatin sites. Therefore, HIV-1 MLOs orchestrate viral events priorto the integration step and create a favorable environment for the viral replication. This study uncovers single functional host–viralcomplexes in their nuclear landscape, which is markedly restructured by HIV-1.Viviana Scoca Renaud Morin Maxence Collard Jean-Yves Tinevez Francesca Di Nunzio 2022Journal of Molecular Cell Biology2022,14,11:0
