TL;DR: In the peripheral blood mononuclear cells of COVID-19 patients, the authors observed reduced expression of human leukocyte antigen class DR (HLA-DR) and proinflammatory cytokines by myeloid cells as well as impaired mammalian target of rapamycin (mTOR) signaling and interferon-α (IFN-α) production by plasmacytoid dendritic cells.

TL;DR: Analysis of plasma from patients infected by SARS-CoV-2 or SARV, and from infected or immunized mice shows cross-reactivity in antibody binding to the spike protein is common, but cross-neutralization of the live viruses may be rare, indicating the presence of non-neutralizing antibody response to conserved epitopes in the spike.

TL;DR: Using IgG ELISA based on the RBD of the spike protein to screen sera for SARS-CoV-2 antibody, followed by confirmation using PRNT90, is a valid approach for large-scale sero-epidemiology studies.

TL;DR: The results show that while cross-reactivity in antibody binding to the spike protein is common, cross-neutralization of the live viruses is rare, indicating the presence of non-neutralizing antibody response to conserved epitopes in the spike.

TL;DR: A retrospective study to compare the therapeutic responses of this regimen in patients infected with genotype 6 and genotype 1 and to evaluate the effectiveness of pegylated interferon and ribavirin treatment.
