    HIV-1 integrase tetramers are the antiviral target of pyridine-based allosteric integrase inhibitors

    Pratibha C Koneru, Ashwanth C Francis ... Mamuka Kvaratskhelia
    Pyridine-based allosteric inhibitors selectively target HIV-1 integrase tetramers and exhibit enhanced antiviral activity against a dolutegravir resistant mutant virus indicating potential clinical benefits for combining these two classes of inhibitors.

    Impact of a decade of successful antiretroviral therapy initiated at HIV-1 seroconversion on blood and rectal reservoirs

    Eva Malatinkova, Ward De Spiegelaere ... Linos Vandekerckhove
    An early start to long-term antiretroviral therapy limits the size of the HIV-1 reservoir more effectively than treatment that starts later.

    The anti-caspase 1 inhibitor VX-765 reduces immune activation, CD4+ T cell depletion, viral load, and total HIV-1 DNA in HIV-1 infected humanized mice

    Mathieu Amand, Philipp Adams ... Carole Seguin-Devaux
    Inflamasomme inhibition prevents immune activation, HIV-1 pathogenesis and the splenic content of HIV-1 total DNA in humanized mice when administrated early after HIV-1 infection.

    N6-methyladenosine of HIV-1 RNA regulates viral infection and HIV-1 Gag protein expression

    Nagaraja Tirumuru, Boxuan Simen Zhao ... Li Wu
    Human proteins that add or remove the methyladenosine modification of cellular RNA, or recognize methylated RNA significantly affect HIV-1 infection or viral protein synthesis in cells, suggesting an important role for HIV-1 RNA methylation in regulating viral replication.

    How HIV-1 Nef hijacks the AP-2 clathrin adaptor to downregulate CD4

    Xuefeng Ren, Sang Yoon Park ... James H Hurley
    The structure of the Nef:AP-2 complex has been determined and used as the basis of a model that explains how HIV-1 Nef downregulates the CD4 receptor from the surface of the infected cells.

    Population genomics of intrapatient HIV-1 evolution

    Fabio Zanini, Johanna Brodin ... Richard A Neher
    Whole genome deep sequencing of many longitudinally sampled HIV-1 populations reveals that reversions towards ancestral HIV-1 genome sequences occur throughout the course of infection.

    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.

    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.

    Structural basis for potent and broad inhibition of HIV-1 RT by thiophene[3,2-d]pyrimidine non-nucleoside inhibitors

    Yang Yang, Dongwei Kang ... Thomas A Steitz
    High-resolution structures of HIV-1 RT in complex with two newly developed non-nucleoside inhibitors explain how they retain antiviral activities against drug-resistant RT mutants with considerably reduced susceptibility to rilpivirine.

    Structural basis of HIV-1 Vpu-mediated BST2 antagonism via hijacking of the clathrin adaptor protein complex 1

    Xiaofei Jia, Erin Weber ... Yong Xiong
    HIV-1 viral protein u (Vpu) can stimulate novel versions of canonical interactions with the clathrin adaptor AP1 to counteract the host antiviral protein BST2.
