|
|
| Investigators showed that patients with severe COVID-19 produced a unique serologic signature, including an increased likelihood of IgG1 with afucosylated Fc glycans. [Nature Immunology] |
|
|
|
| Adult COVID-19 cohorts had anti-spike IgG, IgM and IgA antibodies, as well as anti-nucleocapsid IgG antibody, while children with and without multisystem inflammatory syndrome-C had reduced breadth of anti-SARS-CoV-2-specific antibodies. [Nature Immunology] |
|
|
|
| Researchers applied single-molecule Fluorescence Resonance Energy Transfer imaging to observe conformational dynamics of S on virus particles. [Cell Host & Microbe] |
|
|
|
| Scientists performed RNA structure probing to obtain single-base resolution secondary structure maps of the full SARS-CoV-2 coronavirus genome both in vitro and in living infected cells. [Nucleic Acids Research] |
|
|
|
| Investigators demonstrated that ACE2‐Fc could specifically abrogate virus replication by blocking the entry of SARS‐CoV‐2 spike‐expressing pseudotyped virus into both ACE2‐expressing lung cells and lung organoids. [EMBO Molecular Medicine] |
|
|
|
| Mass spectrometry was used to identify 526 unique sequences from SARS-CoV-2 spike glycoprotein extracellular domain in a complex with human leukocyte antigen class II molecules on antigen presenting cells from a panel of healthy donors selected to represent a majority of allele usage from this highly polymorphic molecule.

|
| The authors used single-cell transcriptomics and CyTOF-based single-cell protein quantification to characterize peripheral immune cells during Ebola virus infection in rhesus monkeys. [Cell] |
|
|
|
| Researchers evaluated gene expression profiles in cells from whole blood elicited in naive subjects receiving the hepatitis B surface antigen formulated with different adjuvants. [Science Translational Medicine] |
|
|
|
| Scientists investigated the humoral immune correlates of protection from cytomegalovirus (CMV) acquisition in populations of CMV-seronegative adolescent and postpartum women who received the gB/MF59 vaccine. [Science Translational Medicine] |
|
|
|
| Investigators identified diverse RNA viruses in N. crassa and other Neurospora species, and showed that N. crassa supported the replication of these viruses as well as some viruses from other fungi. [Nature Communications] |
|
|
|
| Scientists report induction of a protective anti-Zika virus (ZIKV) CD8+ T cell response in the HLA-B*0702 Ifnar1−/− transgenic mice using an alphavirus-based replicon RNA vaccine expressing ZIKV nonstructural protein NS3, a potent T cell antigen. [Science Advances] |
|
|
|
| Researchers found that expression of the HIV‐1 pathogenesis factor NEF in CD4 T cells undermines their helper function and impairs cognate B‐cell functions including mounting of efficient specific IgG responses. [EMBO Journal] |
|
|
|
| Investigators conducted a randomized, observer-blind, comparator-controlled, or quadrivalent recombinant influenza vaccine, safety and immunogenicity trial of quadrivalent nanoparticle influenza vaccine in healthy adults aged ≥65 years. [Clinical Infectious Diseases] |
|
|
|
|
| The authors analyze a selection of existing assays for measuring antibody-mediated virus neutralization and animal models of infection with severe acute respiratory syndrome coronavirus 2 and provide a framework for comparing results between studies and reconciling observed differences in the effects of interventions.
