    Nanoengineered Red Blood Cells Loaded with TMPRSS2 and Cathepsin L Inhibitors Block SARS-CoV-2 Pseudovirus Entry into Lung ACE2+ Cells

    Investigators constructed dual-drug-combined nanocarriers conjugated with an anti-hACE2 antibody and employed red blood cell (RBC)-hitchhiking, termed “Nanoengineered RBCs,” for targeting lung cells.

    Integrated Multi-Omics Analyses Identify Anti-Viral Host Factors and Pathways Controlling SARS-CoV-2 Infection

    Researchers performed a genome-wide CRISPR dropout screen and integrate analyses of the multi-omics data of the CRISPR screen, genome-wide association studies, single-cell RNA-Seq, and host-virus proteins or protein/RNA interactome.

    Airborne Transmission Efficiency of SARS-CoV-2 in Syrian Hamsters Is Not Influenced by Environmental Conditions

    Scientists compared the ancestral SARS-CoV-2 Lineage A with the more transmissible Delta Variant of Concern. Airborne transmission was evaluated using SARS-CoV-2 infected donor animals at 24 hour post inoculation.

    Defining Parameters that Modulate Susceptibility and Protection to Respiratory Murine Coronavirus MHV1 Infection

    Researchers used an established SARS-like murine model in which responses to primary and/or secondary challenges with murine hepatitis virus type 1 (MHV-1) were analyzed.

    Abstract

    Cytokine Signature in Convalescent SARS-CoV-2 Patients with Inflammatory Bowel Disease Receiving Vedolizumab

    Investigators found a cytokine signature in patients receiving vedolizumab who were seropositive compared with seronegative for SARS-CoV-2 antibodies that may be linked to repeated SARS-CoV-2 infections.

    Alveolar Macrophage-Expressed Plet1 Is a Driver of Lung Epithelial Repair after Viral Pneumonia

    Investigators revealed that placenta-expressed transcript 1 (Plet1) was released from alveolar macrophages, and acted as important mediator of macrophage-epithelial cross-talk during lung repair by inducing proliferation of alveolar epithelial cells and re-sealing of the epithelial barrier.

    Single-Cell Sequencing Reveals Functional Alterations in Tuberculosis

    Investigators described the development of a new technological platform to elucidate the immune function differences in individuals with tuberculosis, integrating single-cell RNA sequencing and cell surface antibody sequencing to provide both genomic and phenotypic information from the same samples.

    Mammalian Target of Rapamycin Complex 1 Activation in Macrophages Contributes to Persistent Lung Inflammation following Respiratory Tract Viral Infection

    C57BL/6 mice were infected with influenza A/PR/8/34 as a model for severe viral lung infection and allowed to recover for 21 days. Mice were treated with rapamycin, a well-characterized mammalian target of rapamycin complex 1 inhibitor, on days 12 to 20 after infection, a time period after viral clearance.

    Abstract

    Polyclonal Anti-whole Cell IgY Passive Immunotherapy Shields against P. aeruginosa-Induced Acute Pneumonia and Burn Wound Infections in Murine Models

    Scientists evaluated the protective efficacy of polyclonal avian antibodies raised against inactivated whole cells of the PAO1 strain in murine models of acute pneumonia and burn wound. The efficacy of generated antibodies was evaluated against different Pseudomonas aeruginosa strains.
