Article Synopsis
  • - The study investigated the safety and immune response of an intranasal vaccine (Ad5-S-Omicron) for SARS-CoV-2, showing that higher levels of nasal IgA are linked to lower infection risk from the Omicron variant.
  • - Conducted on 128 healthcare workers who had previously received COVID vaccines, the trial found that mild adverse effects occurred with the vaccine, while significant increases in nasal sIgA and serum neutralizing antibodies were observed after the doses.
  • - Despite a surge in infections post-vaccination due to policy changes in China, none of the participants experienced symptomatic infections 90 days after receiving the second dose, suggesting strong immune response from the vaccine.

Article Synopsis
  • - The study highlights that intranasal vaccination with a specific adenovirus vector can enhance protective nasal immunity (sIgA) against the Omicron variant of SARS-CoV-2, especially in individuals previously vaccinated with the original vaccine.
  • - Results showed that nasal sIgA is considerably more effective than serum antibodies in binding to and neutralizing Omicron subvariants, remaining potent against emerging strains like XBB and BA.2.86.
  • - The findings suggest that intranasal vaccines could be crucial in creating a rapid and robust immune response in the upper respiratory tract, serving as a frontline defense against evolving variants of the virus.

Article Synopsis
  • Scientists studied a special part of the coronavirus called the spike protein, which changes over time and affects how our bodies fight the virus with antibodies.
  • They found an antibody called D1F6 that works really well against many new versions of the virus, including a recent one called XBB.1.5.
  • Some changes in the virus's spike protein can make it harder for D1F6 to work, but several changes together can block it much better, showing how the virus can avoid being attacked by our immune defenses.

Acute kidney injury (AKI) progression to chronic kidney disease (CKD) represents a unique renal disease setting characterized by early renal cellular injury and regulated cell death, and later renal fibrosis, of which the critical role and nature of ferroptosis are only partially understood. Here, we report that renal tubular epithelial ferroptosis caused by HDAC3 (histone deacetylase 3) aberration and the resultant GPX4 suppression drives AKI-CKD progression. In mouse models of AKI-CKD transition induced by nephrotoxic aristolochic acid (AA) and folic acid (FA), renal tubular epithelial ferroptosis occurred early that coincided with preferential HDAC3 elevation and marked suppression of a core anti-ferroptosis enzyme GPX4 (glutathione peroxidase 4).

Although the ecological importance of soil viruses is increasingly recognized, how soil viruses regulate the diversity, structure and succession of microbial communities has not been well understood. Here, we conducted an incubation experiment by mixing soil viruses and bacteria in different ratios, and tracked the changes in viral and bacterial cell abundances as well as bacterial community composition. Our results revealed that viral predation predominantly targeted host lineages that are r-strategists and was a key regulator of the succession of bacterial communities.

Background: As an immune marker, serum soluble programmed cell death ligand-1 (sPD-L1) is significantly increased in sepsis and is predictive of mortality. We investigated the prognostic value of sPD-L1 in postseptic immunosuppression and progression to chronic critical illness (CCI). Methods: Adults with sepsis in intensive care units (ICUs) for the first time were screened and assigned to either a CCI group (ICU stay ≥14 days with persistent organ dysfunction) or a rapid recovery (RAP) group based on clinical outcome.

Levels of neutralizing antibodies (NAb) after vaccine against coronavirus disease 2019 (COVID-19) can be detected using a variety of methods. A critical challenge is how to apply simple and accurate methods to assess vaccine effect. In a population inoculated with three doses of the inactivated Sinopharm/BBIBP vaccine, we assessed the performance of chemiluminescent immunoassay (CLIA) in its implementation to detect severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) specific antibodies, as well as the antibody kinetics of healthcare workers throughout the course of vaccination.

In vaccinees who were infected with SARS-CoV in 2003, we observed greater antibody responses against spike and nucleoprotein of both SARS-CoV-2 and SARS-CoV after a single dosage of inactivated SARS-CoV-2 vaccine. After receiving the second vaccination, antibodies against RBD of SARS-CoV-2 Wuhan, Beta, Delta, and recently emerged Omicron are significantly higher in SARS-CoV experienced vaccinees than in SARS-CoV naïve vaccinees. Neutralizing activities measured by authentic viruses and pseudoviruses of SARS-CoV, SARS-CoV-2 Wuhan, Beta, and Delta are greater in SARS-CoV experienced vaccinees.

Supplemental oxygen is commonly used to treat severe respiratory failure, while prolonged exposure to hyperoxia can induce acute lung injury characterized by the accumulation of reactive oxygen species (ROS) and pulmonary inflammation. Dysregulation of microRNAs contributes to multiple diseases, including hyperoxia-induced acute lung injury (HALI). In this study, we explored the roles of miR-20b in mediating the response of type II alveolar epithelial cells (ACE IIs) to hyperoxia and the potential underlying mechanisms.
