    HIV-1 uncoating by release of viral cDNA from capsid-like structures in the nucleus of infected cells

    Thorsten G Müller, Vojtech Zila ... Hans-Georg Kräusslich
    HIV-1 capsids enter the host cell nucleus, where they are partially disrupted to release the viral genome upon completion of reverse transcription.

    TRIM28 promotes HIV-1 latency by SUMOylating CDK9 and inhibiting P-TEFb

    Xiancai Ma, Tao Yang ... Hui Zhang
    TRIM28 was found to be a versatile dual-function latency contributor by bridging both suppressive epigenetic modifications and RNAP II transcriptional-pausing, and can be a novel target to develop latency-reversing agents.

    HIV-1 nuclear import in macrophages is regulated by CPSF6-capsid interactions at the nuclear pore complex

    David Alejandro Bejarano, Ke Peng ... Hans-Georg Kräusslich
    Interaction of HIV capsids with the cellular protein cleavage-and-polyadenylation factor 6 at the inner side of nuclear pores promotes nuclear entry of the viral replication complex in primary human macrophages.

    Functional development of a V3/glycan-specific broadly neutralizing antibody isolated from a case of HIV superinfection

    Mackenzie M Shipley, Vidya Mangala Prasad ... Julie M Overbaugh
    A bnAb derived from a case of HIV superinfection has distinct qualities from other HIV-specific bnAbs, including framework residues that contribute to neutralization breadth and a unique viral escape profile.

    High-resolution mapping of the neutralizing and binding specificities of polyclonal sera post-HIV Env trimer vaccination

    Adam S Dingens, Payal Pratap ... Jesse D Bloom
    HIV vaccine-induced binding and neutralizing antibody epitope specificities were mapped at high resolution directly from polyclonal sera, overcoming shortcomings in traditional serum mapping approaches and enabling highly detailed vaccine design.

    Quantitative microscopy of functional HIV post-entry complexes reveals association of replication with the viral capsid

    Ke Peng, Walter Muranyi ... Hans-Georg Kräusslich
    A robust method to quantitatively visualize HIV-1 replication complexes in infected cells shows that these complexes remain associated with the viral capsid beyond nuclear import in primary macrophages.

    A molecular tweezer antagonizes seminal amyloids and HIV infection

    Edina Lump, Laura M Castellano ... Jan Münch
    CLR01 is a small molecule that could be an effective topical microbicide to eliminate HIV (and other enveloped viruses), and to antagonize host-encoded amyloid fibrils that promote HIV infection.

    Selection of HIV-1 for resistance to fifth-generation protease inhibitors reveals two independent pathways to high-level resistance

    Ean Spielvogel, Sook-Kyung Lee ... Ronald Swanstrom
    New HIV-1 protease inhibitor designs result in more potent inhibitors with high genetic barriers to resistance and the ability to lead virus evolution down less fit pathways when resistance occurs.

    HIV-1 Vpu is a potent transcriptional suppressor of NF-κB-elicited antiviral immune responses

    Simon Langer, Christian Hammer ... Daniel Sauter
    By inhibiting the activation of NF-κB, HIV-1 Vpu exerts much broader immunosuppressive effects than previously anticipated and may be an important determinant of chronic inflammation in HIV-1 infected individuals.
