This virus also infects various bird species including pigeons; however, information on avian rotavirus A (ARVA) infection in pigeon populations in Japan is limited. Here, we retrospectively report the genetic characterization based on whole-genome sequences of two Japanese ARVA isolates from pigeons in 2012. The isolates were obtained by inoculation into primary chicken kidney cell cultures and subsequently subjected to near-complete genome sequencing using an NGS system. The genotype constellation of the two ARVA isolates was G18-P[17]-I4-R4-C4-M4-A4-N4-T4-E19-H4, which were identical to those derived from several pigeons. Genetic analysis based on each segment revealed that the genomic sequences of all 11 genes from these ARVAs are closely related to those of ARVAs from foreign countries such as Germany, Italy, or China rather than those of the Japanese ARVAs in previous reports. These data suggest an ancestor common to the ARVA analyzed in this study might be distributed and maintained worldwide.

In this study, we identify S100A9 as a macrophage-derived alarmin that is markedly elevated in CRSwNP tissues. Integrative analyses of public bulk transcriptomic datasets and single-cell RNA-sequencing atlases demonstrated that S100A9 expression was predominantly enriched in macrophage clusters, where it showed strong co-expression with canonical M1-associated markers, while exhibiting limited expression in epithelial cell subsets. Spatial and correlation analyses further supported a close association between S100A9⁺ macrophages and epithelial barrier–related gene signatures. Functionally, shRNA-mediated silencing of S100A9 attenuated M1-like macrophage polarization, as evidenced by reduced expression of pro-inflammatory mediators and polarization markers, accompanied by a shift toward a less inflammatory macrophage phenotype. Conditioned media derived from S100A9-deficient macrophages significantly mitigated epithelial injury, leading to restoration of epithelial barrier integrity, as indicated by enhanced expression of tight junction proteins, including occludin and claudins. Importantly, S100A9 knockdown disrupted the pathogenic macrophage–epithelial inflammatory feedback loop, thereby dampening sustained inflammatory signaling and limiting epithelial barrier breakdown that perpetuates tissue damage in CRSwNP. Clinically, elevated S100A9 levels correlated with disease severity indices and effectively distinguished a macrophage-enriched inflammatory endotype of CRSwNP, highlighting S100A9 as both a mechanistic driver and a potential biomarker for disease stratification.

However, the incidence of sporadic events and outbreaks in recent years has posed a significant challenge to this goal. To access the ongoing infections and the effectiveness of immunization efforts, we evaluated the presence of anti-rubella IgM and IgG antibodies, which serve as indicators of ongoing infection and immune protection, respectively. Serum samples from individuals presenting with suspected rubella symptoms were collected and referred to the State Level Virus Research and Diagnostic Laboratory (SL-VRDL) at ICMR-NIRTH, Jabalpur between 1st May 2023 to 30th April 2024 for anti-rubella IgM and IgG analysis. Concurrently, samples from healthy pregnant women, attending Netaji Subhash Chandra Bose Medical College & Hospital, Jabalpur were obtained during the same period to assess the prevalence of maternal immunity against rubella. Collected samples were tested for rubella specific IgM and IgG antibody using ELISA. Rubella IgM seropositivity rate during the study period was 7.2% across all age groups, indicating ongoing transmission of rubella in central India. Rubella IgG seropositivity, reflecting immunity, was 81.0%, among all age groups, demonstrating a high level of immunity against the rubella virus in this region. Among pregnant women, rubella IgG seropositivity was 89.6%, suggesting that most pregnant women of reproductive age are having protection against rubella infection. The finding indicates that rubella elimination efforts are on the right track, and that the vaccination program is broadly effective. However, continuous detection of IgM positive cases, particularly in young children, highlights, immunity gaps, that may hinder timely elimination. These gaps could be due to logistical, cultural, and educational barriers and require further intensive efforts towards active immunization.

Despite its growing public health impact, no licensed vaccine or antiviral therapy currently exists, underscoring the urgent need for an effective preventive strategy. In this study, an immunoinformatics-based approach was employed to design a novel multi-epitope vaccine (MEV) against RRV, where conserved and antigenic cytotoxic T-lymphocyte (CTL), helper T-lymphocyte (HTL), and B-cell epitopes were predicted from structural proteins (capsid and envelope glycoproteins E1 and E2) as well as selected non-structural protein regions, followed by their rational assembly into a vaccine construct using appropriate linkers and an immune-stimulatory adjuvant. Conserved and antigenic cytotoxic T-lymphocyte (CTL), helper T-lymphocyte (HTL), and B-cell epitopes were predicted from structural and non-structural proteins and linked with appropriate linkers, while β-defensin was incorporated as an adjuvant to enhance immunogenicity. The vaccine construct underwent modeling, refinement, and structural validation using PSIPRED, AlphaFold, and GalaxyRefine. Molecular docking analyses with immune receptors (TLR8 and HLA) and molecular dynamics (MD) simulations evaluated receptor binding affinity and structural stability. The C-ImmSim server was used to simulate immune responses, and codon optimization ensured suitability for Escherichia coli expression. The designed MEV exhibited strong antigenicity (0.79), stability, and solubility, with a molecular weight of ~30 kDa and theoretical pI of 9.98. Structural validation revealed over 95% of residues in favored Ramachandran regions, and docking analysis showed predicted interaction with TLR8 (- 1712.2 kJ/mol).

LAP was quantified by flow cytometry using labeled zymosan as a stimulus to engage LAP and LC3 antibodies to detect LC3 recruitment. LAP engagement was evaluated as the integrated mean fluorescence intensity of LC3 in zymosan-positive cells.

Furthermore, LAP in both neutrophils and monocytes correlated with the stage of fibrosis from F0 to F2, indicating that as the process of fibrosis progressed in the early stages, LAP activity increased. No differences in LAP were observed between treatment-naïve and those who received direct acting antiviral therapy and achieved sustained virologic response (SVR), suggesting that the process of fibrosis had a more significant impact on LAP, rather than the presence or absence of HCV infection.

Herpesviruses frequently modulate NF-κB, a central regulator of inflammatory gene expression, to promote viral gene expression and replication. The HHV-6A tegument protein U14 activates NF-κB, but whether this activity is conserved in HHV-6B and contributes to infection-associated outputs has remained unclear. Here, we evaluated HHV-6A and HHV-6B U14 in a transient NF-κB reporter assay and examined U14 function during HHV-6B infection using two independent U14-targeting shRNAs. Both U14 orthologs activated an NF-κB reporter. During HHV-6B infection in MT-4 cells, U14 knockdown reduced phosphorylation of p65 (Ser536) and was accompanied by decreased mRNA levels of the immediate-early viral gene IE2 and the early viral genes U27 and U38, as well as reduced release of viral genomes into culture supernatants. U14 knockdown also reduced IL-2, IL-6, and IL-8 transcript levels, consistent with attenuation of an NF-κB–linked cytokine transcriptional program.
