    Enhanced SARS-CoV-2 Humoral Immunity Following Breakthrough Infection Builds upon the Preexisting Memory B Cell Pool

    The authors investigated how B cells respond to repeated SARS-CoV-2 antigen exposure by Wu01 booster vaccination and Omicron breakthrough infection by performing a molecular longitudinal analysis of the memory B cell pool.

    Abstract

    Initial Productive and Latent HIV Infections Originate In Vivo by Infection of Resting T Cells

    Researchers found that direct infection of resting CD4+ T cells was correlated with the availability of susceptible target cells in lymphoid tissues largely restricted to resting CD4+ T cells in which expression of pTEFb enabled productive infection.

    Structure-Based Discovery of Dual Pathway Inhibitors for SARS-CoV-2 Entry

    Investigators identified compounds that showed potent inhibition of host proteases and determined their complex structures with their respective targets. Furthermore, they showed that applying inhibitors simultaneously that blocked both entry pathways had a synergistic antiviral effect.

    Nicotinamide Mononucleotide Impacts HIV-1 Infection by Modulating Immune Activation in T Lymphocytes and Humanized Mice

    Investigators examined HIV-1 integrated DNA or transcribed RNA, intracellular p24 protein, and T cell activation markers in CD4+ T cells including in vitro HIV-1-infected cells, reactivated patient-derived cells, and in HIV-1-infected humanized mice, under NMN treatment.

    Self-Assembled Multiepitope Nanovaccine Provides Long-Lasting Cross-Protection Against Influenza Virus

    Multiple linear epitopes from the conserved stem domain of hemagglutinin and the ectodomain of matrix protein 2 were combined with the Helicobacter pylori ferritin, a stable self-assembled nanoplatform, to develop an influenza multiepitope nanovaccine, named MHF.

    Abstract

    Conjugation of HIV-1 Envelope to Hepatitis B Surface Antigen Alters Vaccine Responses in Rhesus Macaques

    Researchers developed an innovative conjugate vaccine regimen that used a modified vaccinia virus Ankara co-expressing HIV-1 envelope and the hepatitis B virus surface antigen as a prime, followed by two envelope–hepatitis B virus surface antigen conjugate protein boosts.
