Dynamic, Single-cell Monitoring of RNA Modifications Response to Viral Infection Using a Genetically Encoded Live-cell RNA Methylation Sensor.
Angew Chem Int Ed Engl

RNA modifications, such as N6-methylation of adenosine (m6A), serve as key regulators of cellular behaviors, and are highly dynamic; however, tools for dynamic monitoring of RNA modifications in live cells are lacking. Here, we develop a genetically encoded live-cell RNA methylation sensor that can dynamically monitor RNA m6A level at single-cell resolution. The sensor senses RNA m6A in cells via affinity-induced cytoplasmic retention using a nuclear location sequence-fused m6A reader.

Unlabelled: The SARS-CoV-2 JN.1 lineage emerged in late 2023 and quickly replaced the XBB lineages, becoming the predominant Omicron variant worldwide in 2024. We estimate the epidemiologic impact of this SARS-CoV-2 lineage replacement in Brazil and we further assessed the cross-reactive neutralizing antibody (NAb) responses in a cohort of convalescent Brazilian patients infected during 2023.

Centro Nacional de Gripe de Valladolid (GISRS/WHO), Spain.
Despite high initial vaccination rates, Spain's current COVID-19 vaccination coverage in recommended groups does not meet WHO targets. For the upcoming season, challenges include revising vaccination age, updating risk groups, and unifying criteria with flu vaccine co-administration. European Commission's advance purchase agreements limit access to certain vaccines, and the need for vaccines effective against current variants adds administrative complexities.

Department of Pathology, Johns Hopkins School of Medicine, Baltimore, Maryland, USA.
Background: The Association for the Advancement of Blood and Biotherapies guidelines recommend the use of high-titer COVID-19 convalescent plasma (CCP) for patients with SARS-CoV-2 at high risk of disease progression, including those who are immunocompromised. We hypothesized that conventional plasma units have comparable neutralizing antibody levels to CCP.
Study Design And Methods: Conventional plasma and CCP units were obtained from blood suppliers.
Broad-spectrum affinity chromatography of SARS-CoV-2 and Omicron vaccines from ligand screening to purification.

Electronic address:
Emerging variants of SARS-CoV-2 pose great technological and regulatory challenges to vaccine manufacturing, especially in downstream processing. To address this dilemma, the development of broad-spectrum affinity chromatography for the purification of wild-type SARS-CoV-2 and its variants is crucial. We propose a comprehensive strategy to achieve this goal via the identification of high-affinity peptides by affinity selection of phage display and next-generation sequencing (NGS) and the evaluation of chromatographic performance.
