A selective inhibitor of eIF2alpha dephosphorylation protects cells from ER stress.
(Science (New York, N.Y.), 2005-02)Most protein phosphatases have little intrinsic substrate specificity, making selective pharmacological inhibition of specific dephosphorylation reactions a challenging problem. In a screen for small molecules that protect ... -
ADAP2 Is an Interferon Stimulated Gene That Restricts RNA Virus Entry.
(PLoS pathogens, 2015-09-15)Interferon stimulated genes (ISGs) target viruses at various stages of their infectious life cycles, including at the earliest stage of viral entry. Here we identify ArfGAP with dual pleckstrin homology (PH) domains 2 (ADAP2) ... -
Analysis of Epstein-Barr virus-regulated host gene expression changes through primary B-cell outgrowth reveals delayed kinetics of latent membrane protein 1-mediated NF-κB activation.
(Journal of virology, 2012-10)Epstein-Barr virus (EBV) is an oncogenic human herpesvirus that dramatically reorganizes host gene expression to immortalize primary B cells. In this study, we analyzed EBV-regulated host gene expression changes following ... -
Anti-AIDS agents 81. Design, synthesis, and structure-activity relationship study of betulinic acid and moronic acid derivatives as potent HIV maturation inhibitors.
(J Med Chem, 2010-04-22)In our continuing study of triterpene derivatives as potent anti-HIV agents, different C-3 conformationally restricted betulinic acid (BA, 1) derivatives were designed and synthesized in order to explore the conformational ... -
Anti-HIV Potential of Beesioside I Derivatives as Maturation Inhibitors: Synthesis, 3D-QSAR, Molecular Docking and Molecular Dynamics Simulations.
(International journal of molecular sciences, 2023-01)HIV-1 maturation is the final step in the retroviral lifecycle that is regulated by the proteolytic cleavage of the Gag precursor protein. As a first-in-class HIV-1 maturation inhibitor (MI), bevirimat blocks virion maturation ... -
BPIFB3 regulates autophagy and coxsackievirus B replication through a noncanonical pathway independent of the core initiation machinery.
(mBio, 2014-12-09)<h4>Unlabelled</h4>Enteroviruses require autophagy to facilitate the formation of autophagosome (AP)-like double-membrane vesicles that provide the scaffolding for RNA replication. Here, we identify bactericidal/permeabi... -
Epstein-Barr virus induces global changes in cellular mRNA isoform usage that are important for the maintenance of latency.
(Journal of virology, 2013-11)Oncogenic viruses promote cell proliferation through the dramatic reorganization of host transcriptomes. In addition to regulating mRNA abundance, changes in mRNA isoform usage can have a profound impact on the protein output ... -
HLA class II-Restricted CD8+ T cells in HIV-1 Virus Controllers.
(Scientific reports, 2019-07-15)A paradigm shifting study demonstrated that induction of MHC class E and II-restricted CD8+ T cells was associated with the clearance of SIV infection in rhesus macaques. Another recent study highlighted the presence of ... -
Imaging-Based Reporter Systems to Define CVB-Induced Membrane Remodeling in Living Cells.
(Viruses, 2020-09-25)Enteroviruses manipulate host membranes to form replication organelles, which concentrate viral and host factors to allow for efficient replication. However, this process has not been well-studied in living cells throughout ... -
In vitro and in vivo functions of SARS-CoV-2 infection-enhancing and neutralizing antibodies
(Cell, 2021)SARS-CoV-2-neutralizing antibodies (NAbs) protect against COVID-19. A concern regarding SARS-CoV-2 antibodies is whether they mediate disease enhancement. Here, we isolated NAbs against the receptor-binding domain (RBD) ... -
Initial HIV-1 antigen-specific CD8+ T cells in acute HIV-1 infection inhibit transmitted/founder virus replication.
(J Virol, 2012-06)CD8-mediated virus inhibition can be detected in HIV-1-positive subjects who naturally control virus replication. Characterizing the inhibitory function of CD8(+) T cells during acute HIV-1 infection (AHI) can elucidate ... -
Preexisting compensatory amino acids compromise fitness costs of a HIV-1 T cell escape mutation.
(Retrovirology, 2014-11-19)BACKGROUND: Fitness costs and slower disease progression are associated with a cytolytic T lymphocyte (CTL) escape mutation T242N in Gag in HIV-1-infected individuals carrying HLA-B*57/5801 alleles. However, the impact of ...
