Abstract
Duck plague virus (DPV) is the only herpes virus known to be transmissible among aquatic animals, leading to immunosuppression in ducks, geese and swans. Long noncoding RNAs (LncRNA) are known to participate in viral infections, acting as either immune defenders or viral targets to evade the host response, but their precise roles in waterfowl virus infections are yet to be fully understood. This study aimed to investigate the role of LncRNA in DPV-induced innate immune responses. Results showed that DPV infection greatly upregulated Lnc BTU expression in duck embryo fibroblasts (DEF) and Lnc BTU promoted DPV replication. Mechanically, 4 DPV proteins, namely UL46, UL42, VP22 and US10, interacted with Lnc BTU, leading to its upregulation. Specifically, Lnc BTU facilitated the production of DNA polymerase by enhancing UL42 expression, thereby promoting DPV replication. Additionally, Lnc BTU suppressed STAT1 expression by targeting the DNA binding domain (DBD) and promoting STAT1 degradation through the proteasome pathway. Furthermore, Lnc BTU inhibited the production of key antiviral factors such as IFN-α, IFN-β, MX and OASL during DPV infection. Treatment with 2 JAK-STAT pathway activators in DEFs resulted in the inhibition of Lnc BTU expression and DPV replication. Interestingly, DPV infection led to a decrease in STAT1 levels, which was reversed by Si-Lnc BTU. These findings suggest that DPV relies on Lnc BTU to inhibit the activation of the JAK-STAT pathway and limit the production of type 1 interferons (IFN) to complete immune evasion. Our study highlights the novel role of DPV proteins UL46, UL42, VP22, US10 as RNA-binding proteins in modulating the innate antiviral immune response, and discover the role of a new host factor, Lnc BTU, in DPV immune evasion, Lnc BTU and STAT1 can be used as a potential therapeutic target for DPV infection and immune evasion.

Abstract
Duck plague (DP) is a highly contagious viral disease in ducks caused by the duck plague virus (DPV). The DPV, a member of Herpesviridae, poses a severe threat to the waterfowl farming industry worldwide. In this study, we reported a recent outbreak of DPV in domestic laying ducks at 310 days of age from southern China in December 2021. The gross lesion, histopathologic examination, molecular detection, and genetic characterization studies of DPV are described here. As a result, gross lesions such as an enlarged congestive spleen and liver were observed. Liver with vacuolar degeneration and small vacuoles and spleen with hemosiderosis were remarkable microscopic findings. Our results suggested that the liver had the highest viral load, followed by the trachea, pancreas, kidney, brain, spleen, and heart. In addition, DPV was successfully isolated in chicken embryo fibroblast cell culture and designated as DP-GD-305-21. The UL2, UL12, UL41, UL47, and LORF11 genes of DP-GD-305-21 shared a high nucleotide homology with the Chinese virulent (CHv) strain and the Chinese variant (CV) strain. In conclusion, this study reports the isolation and molecular characterization of DPV from a recent outbreak in southern China. Our results contributed to the understanding of the pathological and molecular characterization of currently circulating DPV in China.

Recombinant Muscovy Duck Parvovirus Led to Ileac Damage in Muscovy Ducklings. Viruses 2022; 14:v14071471. [PMID: 35891451 PMCID: PMC9315717 DOI: 10.3390/v14071471] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2022] [Revised: 06/29/2022] [Accepted: 06/29/2022] [Indexed: 02/04/2023] Open
Abstract
Waterfowl parvovirus (WPFs) has multiple effects on the intestinal tract, but the effects of recombinant Muscovy duck parvovirus (rMDPV) have not been elucidated. In this study, 48 one-day-old Muscovy ducklings were divided into an infected group and a control group. Plasma and ileal samples were collected from both groups at 2, 4, 6, and 8 days post-infection (dpi), both six ducklings at a time. Next, we analyzed the genomic sequence of the rMDPV strain. Results showed that the ileal villus structure was destroyed seriously at 4, 6, 8 dpi, and the expression of ZO-1, Occludin, and Claudin-1 decreased at 4, 6 dpi; 4, 6, 8 dpi; and 2, 6 dpi, respectively. Intestinal cytokines IFN-α, IL-1β and IL-6 increased at 6 dpi; 8 dpi; and 6, 8 dpi, respectively, whereas IL-2 decreased at 6, 8 dpi. The diversity of ileal flora increased significantly at 4 dpi and decreased at 8 dpi. The bacteria Ochrobactrum and Enterococcus increased and decreased at 4, 8 dpi; 2, 4 dpi, respectively. Plasma MDA increased at 2 dpi, SOD, CAT, and T-AOC decreased at 2, 4, 8 dpi; 4, 8 dpi; and 4, 6, 8 dpi, respectively. These results suggest that rMDPV infection led to early intestinal barrier dysfunction, inflammation, ileac microbiota disruption, and oxidative stress.

Abstract
A comprehensive study on the pathogenicity and host immune response was conducted in White Pekin ducklings after experimental infection with an Indian isolate of duck enteritis virus (DEV). The virus was found to be highly pathogenic and pantropic, which rapidly multiplied in various organs, mainly in the spleen and liver showing higher viral load with severe pathological lesions and caused 100% mortality. Expression profiles of immune gene transcripts in tissues (liver, spleen, brain) revealed upregulation of proinflammatory cytokines IFN-α, IFN- β, IL-1β, IL-6 and also iNOS with stimulation of TLRs (TLR-2, 3, 21). IFN-α was robustly upregulated (p < 0.05) especially in liver, might be playing role in antiviral innate immunity. Further, massive upregulation of MHC class-I (p < 0.01), expression of Th1 cytokines (IFN-γ & IL-2) and certain Th2 cytokines (IL-4 & IL-10) suggests stimulation of cell mediated as well as humoral immunity. To our knowledge, we are reporting first time about the robust upregulation of MHC class-I in spleen, liver and brain along with expression of certain cytokines in the peripheral blood mononuclear cells (PBMCs) during experimental DEV infection.

Abstract
Interferon regulatory factor 4 (IRF4) is a multifunctional transcription factor that plays an important regulatory role in the interferon (IFN) signaling. IRF4 participates in the process of antivirus, Th cell differentiation and B cell maturation by regulating the expression of IFN and some lymphokines. In this study, Cherry Valley duck IRF4 (duIRF4) was cloned and its cDNA was analyzed. Expression of duIRF4 in a wide variety of tissues and changes in duIRF4 expression due to viral infection also was detected by quantitative real-time PCR. The results show that duIRF4 contains 1,341 bp of ORF encoding a protein with 446 amino acids and contains 3 domains: DNA-binding domain (DBD), IRF-association domain (IAD) and nuclear localization signal (NLS). Quantitative real-time PCR analysis showed that duIRF4 was evenly expressed in all tissues examined, with the highest expression in the spleen, followed by the bursa of Fabricius, and lower in the skin and brain. In addition, expression of duIRF4 in the brain and spleen was significantly upregulated after being infected by duck plague virus, duck Tembusu virus, and novel duck reovirus. These data suggest that duIRF4 may be involved in innate immune response.
