Radical polymerization was used to synthesize and characterize (co)polymers with sodium styrenesulfonate (NaSS), 4-methacryloylamidosalicylic acid (MASA), and -vinylpyrrolidone, which have a low cytotoxicity and a high antiviral activity against the human respiratory syncytial virus. The interaction of copolymers with Tb ions was studied. The complexes formed in dilute aqueous solutions at a concentration of MASA units ⩽ 1 · 10 mol L demonstrate a strong luminescence. The luminescence intensity is independent of copolymer composition, but increases when the NaSS units are substituted with uncharged N-vinylpyrrolidone units. The obtained Tb polymer complexes are promising luminescent sensors for the visualization of biological objects interacting with copolymers.

Unlabelled: Porcine reproductive and respiratory syndrome (PRRS) remains a major threat to animal health and causes substantial economic losses worldwide. The nonstructural protein 11 (NSP11) of the causative agent, PRRS virus (PRRSV), contains a highly conserved nidoviral uridylate-specific endoribonuclease (NendoU) domain essential for viral replication and immune evasion. Targeting NSP11 offers a novel approach to antiviral intervention.

Porcine circovirus type 2 (PCV2) is the primary causative agent of porcine circovirus-associated disease, clinically resulting in immunosuppression and co-infections with other pathogens in infected pigs. The mechanism of PCV2 infection remains unclear. In this study, we firstly found that the tetraspanin CD81 in PK-15 cells interacts with PCV2 Cap protein by using virus overlay protein-binding assay combined with mass spectrometry.

Department of Microbiology and Immunology, University of Michigan, Ann Arbor, Michigan, USA.
Protein kinase R (PKR) is an interferon-induced antiviral protein activated by autophosphorylation in response to double strand DNA (dsRNA) and other stimuli. Activated PKR causes translation inhibition and apoptosis, and it contributes to proinflammatory responses, cell growth, and differentiation. Mouse adenovirus type 1 (MAV-1) counteracts PKR by causing its degradation via a viral protein, early region 4 open reading frame 6 (E4orf6).

Emerging tick-borne orthonairovirus infections pose a growing global concern, with limited understanding of the viral ovarian tumor-like cysteine proteases (vOTUs) encoded by novel orthonairoviruses. These vOTUs, a group of deubiquinylases (DUBs), disrupt the innate immune response. Yezo virus (YEZV), a recently discovered pathogenic orthonairovirus, was first reported in Japan in 2021.
