How long does natural immunity produced by SARS-CoV-2 infection last?

A new study posted to the bioRxiv* preprint server followed the adaptive immune response in convalescent patients from Swedish and Italian cohorts—which had earlier shown long-lasting adaptive immune responses to the G614 strain—for 15 months. Here, specific antibody levels and neutralizing antibody titers were tested against variants of concern (VOCs).

Nucleoside modifications suppress the potential of RNA to activate dendritic cells

A new paper shows that human TLR3, TLR7, and TLR8 receptors are activated with naturally occurring RNA, but this is eliminated once modified nucleosides such as m5C, m6A, m5U s2U, or pseudouridine are incorporated.

A new bacterial two-hybrid assay to study SARS-CoV-2 interactome

Recently, scientists have developed a bacterial two-hybrid (B2H) system to study the PPIs of SARS-CoV-2 in a heterologous non-eukaryotic system. This study is available on the bioRxiv* preprint server. Put simply, the B2H system could be used to analyze the SARS-CoV-2 proteome.

Delta SARS-CoV-2 variant does not make kids sicker than Alpha, study finds

Children are not at risk for more severe COVID-19 disease with Delta compared to earlier severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants, finds a new medRxiv* preprint study. In the first large-scale epidemiological study comparing SARS-CoV-2 infection between variants in children, researchers found children were more likely to be as sick from Delta as they would be if they were infected with the Alpha variant.
