Recently, the emergence of NADC34-like PRRS virus (PRRSV) has made the worldwide circulation of PRRSV more complex. In 2017, the first detection of NADC34-like PRRSV in China was reported, but the pathogenicity and biological characteristics of this novel PRRSV variant remain to be further elucidated. In this study, we conducted analyses of the whole genome sequence and pathogenicity of three NADC34-like PRRSV strains isolated in China. The three strains, designated HeB-05, SD-02, and JL-1152, were isolated using porcine alveolar macrophages (PAMs). However, only HeB-05 demonstrated robust replication in Marc-145 cells, achieving a high viral titer of up to 10^7.57 TCID₅₀/mL. The genomes of SD-02 and JL-1152 have undergone recombination, while no recombination events were detected in the genome of HeB-05. Artificial infection tests revealed that SD-02 and JL-1152 exhibited relatively high virulence to piglets, causing significant fever and mortality, whereas HeB-05 did not cause death in piglets. Following assessments of the immunogenic efficacy of an inactivated vaccine developed using HeB-05 in pig models showed the vaccine provided partial protection against challenge with the parental strain. This study introduces a novel candidate vaccine strain for NADC34-like PRRSV, which holds significant implications for the prevention and control of PRRS.</div></div>","PeriodicalId":23666,"journal":{"name":"Virology","volume":"610 ","pages":"Article 110605"},"PeriodicalIF":2.8,"publicationDate":"2025-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144263194","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In several systems, including plants and insects, parallel antiviral pathways provide redundancy, ensuring host protection even if one pathway is compromised by a virus. However, whether such alternative antiviral mechanisms exist in nematodes beyond RNA interference (RNAi) remains largely unexplored. To address this question and as proof of principle, we conducted a small-scale genetic screen to identify <em>C. elegans</em> genes involved in RNAi-independent antiviral defense (RiAD). The reporter system for this screen was a combination of a GFP-tagged flock house virus replicon, as the readout of efficient viral replication, and an RNAi-deficient triple mutant. The reporter <em>C. elegans</em> strain also carried a recessive <em>E3</em> allele, which suppresses the replication of both flock house virus and Orsay virus. Because this reporter strain lacks a functional RNAi response, any restoration of viral replication in the screen is unlikely due to RNAi disruption, thereby enriching for mutants with defects in RiAD. Upon completing this biased genetic screen we identified ten recessive alleles which were assigned to eight candidate genes. Notably, five of these genes also contributed to RiAD against Orsay virus, indicating a role in broad-spectrum natural antiviral defense. Strikingly, removal of the <em>E3</em> allele in one of the mutant backgrounds resulted in lethal Orsay virus infection, suggesting that RiAD plays a critical role in protecting <em>C. elegans</em> from fatal viral infection in the absence of RNAi under natural conditions.</div></div>","PeriodicalId":23666,"journal":{"name":"Virology","volume":"610 ","pages":"Article 110597"},"PeriodicalIF":2.8,"publicationDate":"2025-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144279883","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

LERV1 is only found in Asian lorises and absent in all other primates. The remarkable similarity of the LERV1 loci between the two species of slow loris indicate that the current <em>N. coucang</em> reference genome may actually be a hybrid of the two species, or a <em>N. bengalensis</em> from a different population as the <em>N. bengalensis</em> reference genome.

We have previously described synergy between NHC and inhibitors of dehydroorotate dehydrogenase (DHODH), an enzyme required for pyrimidine synthesis. Upon DHODH inhibition, the lack of endogenous pyrimidines conceivably enhances NHC incorporation. However, the question remains whether preventing the synthesis of just one pyrimidine base, cytidine, might as well augment the antiviral efficacy of NHC. We tested this by inhibiting CTP synthetases (CTPSs), the cellular enzymes that directly catalyze the synthesis of a cytidine nucleotide. We observed that inhibitors of CTP synthetase (CTPSis), namely cyclopentenyl cytosine (CPEC) as well as STP938 and STP720, display a strong synergy with NHC for diminishing SARS-CoV-2 replication in cell culture, as shown earlier for DHODH inhibitors. NHC and CTPSis in combination prevented the cytopathic effect of SARS-CoV-2 and strongly reduced the release of viral RNA and infectious particles, as well as the synthesis of viral proteins. This combination was also active against an Omicron variant of SARS-CoV-2. Addition of cytidine, but not uridine, rescued virus growth under these conditions. Surprisingly, this synergy was not confirmed in the SARS-CoV-2 animal model in Syrian hamsters. While treatment with the CTPS1 inhibitor STP938 alone strongly diminished virus propagation and COVID pathology, addition of molnupiravir did not augment this effect and even counteracted the benefits of STP938 in vivo.
