Special Issue Information

Dear Colleagues,

Viral infections have always played a critical role in the welfare of wildlife and domestic animals. Throughout history, the significance of animal viruses has gradually increased due to spill-over events, which have caused significant outbreaks in naive populations. Recent examples include the Epizootic Avian Influenza H5N1 (specifically clade 2.3.4.4b), the SARS-CoV-2 pandemic, and the human Ebola outbreaks. Moreover, increasing data supporting the effect of climate change on the prevalence of viral diseases, coupled with the potential for zoonotic and reverse zoonotic events, underscores the importance of adopting a One Health approach to mitigate these issues.

This Issue, titled "Emerging and Re-Emerging Viral Infections in Animals: Clinical, Immunological, Epidemiological and Public Health Aspects" focuses on discovering novel phenomena related to viral infections in animals. This includes the description of novel animal pathogens, disease mechanisms, and the environmental factors that determine viral diseases, among other topics.

We believe this Issue will provide new insights into animal viruses, uncover novel viral agents in animals, and offer new data on emerging and re-emerging pathogens, including those with zoonotic potential. We are confident that this collection of work will significantly contribute to our understanding of this important field.

Avian reticuloendotheliosis (RE) caused by reticuloendotheliosis virus (REV) is an important tumor and immunosuppressive disease posing a serious threat to poultry development. The REV envelope protein, glycoprotein (gp)-90, not only participates in cell receptor binding and viral assembly and release but also induces neutralizing antibody production. However, the antigenic epitope structure of gp90 has not yet been systematically understood. Therefore, in this study, the gp90 envelope protein of a predominant REV strain was prepared using a prokaryotic expression system, and a hybridoma cell line stably secreting the REV gp90 monoclonal antibody was developed via cell fusion and flow cytometry. Notably, a novel linear B-cell epitope, 195REESVRERL203, was identified for the first time in the gp90 of REV using peptide scanning. This epitope was located on the outer side of the gp90 midpiece and was conserved across REV strains. Overall, this study is of great significance for the systematic understanding of REV antigen structure and the development of virus detection methods. Full article

Long non-coding RNAs (lncRNAs) encoded by viruses play crucial roles in viral infection, pathogenesis processes, the interaction between viruses and hosts, and immune escape. Herein, by employing RNA pull-down, mass spectrometry technology, and RNA immunoprecipitation, we identified a host protein (G3BP2) that specifically interacts with the lncRNA encoded by the infectious bronchitis virus (IBV). Additionally, we identified a novel host miRNA (novel-340) in IBV-infected H1299 cells and further verified that novel-340 can target the 3′-UTR (untranslated region) of G3BP2 and downregulate its expression in a dose-dependent manner. We discovered that IBV-lncRNA may facilitate IBV replication in H1299 cells through direct interaction with G3BP2 and/or the regulation of the IBV-lncRNA/novel-340/G3BP2 interactive regulatory network. This work deepens the understanding of the biological function of IBV-lncRNA. Full article
