    TOP STORY

    SARS-CoV-2-Infection- and Vaccine-Induced Antibody Responses Are Long Lasting with an Initial Waning Phase Followed by a Stabilization Phase

    Investigators analyzed the kinetics and durability of the humoral responses to SARS-CoV-2 infection and vaccination using >8,000 longitudinal samples collected over a three-year period in New York City.

    ATG5-Regulated CCL2/MCP-1 Production in Myeloid Cells Selectively Modulates Anti-Malarial CD4+ Th1 Responses

    Researchers demonstrated that ATG5 deficiency in myeloid cells could significantly inhibit the growth of rodent blood-stage malarial parasites by selectively enhancing parasite-specific CD4+ Th1 cell responses. This effect was independent of ATG5-mediated canonical and non-canonical autophagy.

    Abstract

    Human Transferrin Receptor Can Mediate SARS-CoV-2 Infection

    Investigators identified human TfR, one of the most ubiquitously and highly expressed membrane components, as a receptor of SARS-CoV-2. TfR mediated SARS-CoV-2 infection by directly binding to the spike with high affinity and transporting the virus into the host cells.

    Rapid Development of Achalasia After SARS-CoV-2 Infection: Polymerase Chain Reaction Analysis of Esophageal Muscle Tissue

    Researchers prospectively evaluated esophageal muscle for SARS-CoV-2 from patients with rapid-onset achalasia post–COVID-19 and compare them with achalasia predating COVID-19 and achalasia with no COVID-19.

    Abstract

    RNA–RNA Interactions Between Respiratory Syncytial Virus and miR-26 and miR-27 Are Associated with Regulation of Cell Cycle and Antiviral Immunity

    Scientists adapted a biochemical method and analysis pipeline to identify targets of miRNAs in lung cells infected with respiratory syncytial virus.

    Randomized Controlled Trial of Molnupiravir SARS-CoV-2 Viral and Antibody Response in At-Risk Adult Outpatients

    Non-hospitalized participants within five days of SARS-CoV-2 symptoms randomised to receive molnupiravir or Usual Care were recruited to study viral and antibody dynamics and the effect of molnupiravir on viral whole genome sequence from 1437 viral genomes.

    Durable Cross-Protective Neutralizing Antibody Responses Elicited by Lipid Nanoparticle-Formulated SARS-CoV-2 mRNA Vaccines

    Researchers assessed the efficacy of lipid nanoparticles-encapsulated mRNA booster vaccines encoding the spike protein of SARS-CoV-2 for variants of concern and using a predecessor strain spike protein to elicit durable cross-protective neutralizing antibody responses.

    Chlamydia trachomatis Enhances HPV Persistence through Immune Modulation

    Scientists reported that Chlamydia trachomatis (CT) infection supported HPV persistence by further suppressing the functions of Langerhans cells (LCs); in particular, CT further activated the PI3K pathway and inhibited the MAPK pathways in LCs.
