Neuronal miR-9 promotes HSV-1 epigenetic silencing and latency by repressing Oct-1 and Onecut family genes. Nat Commun 2024; 15:1991. [PMID: 38443365 PMCID: PMC10914762 DOI: 10.1038/s41467-024-46057-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2023] [Accepted: 02/07/2024] [Indexed: 03/07/2024] Open
Abstract
Herpes simplex virus 1 (HSV-1) latent infection entails repression of viral lytic genes in neurons. By functional screening using luciferase-expressing HSV-1, we identify ten neuron-specific microRNAs potentially repressing HSV-1 neuronal replication. Transfection of miR-9, the most active candidate from the screen, decreases HSV-1 replication and gene expression in Neuro-2a cells. Ectopic expression of miR-9 from lentivirus or recombinant HSV-1 suppresses HSV-1 replication in male primary mouse neurons in culture and mouse trigeminal ganglia in vivo, and reactivation from latency in the primary neurons. Target prediction and validation identify transcription factors Oct-1, a known co-activator of HSV transcription, and all three Onecut family members as miR-9 targets. Knockdown of ONECUT2 decreases HSV-1 yields in Neuro-2a cells. Overexpression of each ONECUT protein increases HSV-1 replication in Neuro-2a cells, human induced pluripotent stem cell-derived neurons, and primary mouse neurons, and accelerates reactivation from latency in the mouse neurons. Mutagenesis, ChIP-seq, RNA-seq, ChIP-qPCR and ATAC-seq results suggest that ONECUT2 can nonspecifically bind to viral genes via its CUT domain, globally stimulate viral gene transcription, reduce viral heterochromatin and enhance the accessibility of viral chromatin. Thus, neuronal miR-9 promotes viral epigenetic silencing and latency by targeting multiple host transcription factors important for lytic gene activation.

Integrated analyses delineate distinctive immunological pathways and diagnostic signatures for Behcet's disease by leveraging gene microarray data. Immunol Res 2023; 71:860-872.

Abstract
Behcet's disease (BD) is a chronic inflammatory vasculitis and clinically heterogeneous disorder caused by immunocyte aberrations. Comprehensive research on gene expression patterns in BD illuminating its aetiology is lacking. E-MTAB-2713 downloaded from ArrayExpress was analysed to screen differentially expressed genes (DEGs) using limma. Random forest (RF) and neural network (NN) classification models composed of gene signatures were established using the E-MTAB-2713 training set and subsequently verified using GSE17114. Single sample gene set enrichment analysis was used to assess immunocyte infiltration. After identifying DEGs in E-MTAB-2713, pathogen-triggered, lymphocyte-mediated and angiogenesis- and glycosylation-related inflammatory pathways were discovered to be predominant in BD episodes. Gene signatures from the RF and NN diagnostic models, together with genes enriched in angiogenesis and glycosylation pathways, well discriminated the clinical subtypes of BD manifesting as mucocutaneous, ocular and large vein thrombosis involvement in GSE17114. Moreover, a distinctive immunocyte profile revealed T, NK and dendritic cell activation in BD compared to the findings in healthy controls. Our findings suggested that EPHX1, PKP2, EIF4B and HORMAD1 expression in CD14+ monocytes and CSTF3 and TCEANC2 expression in CD16+ neutrophils could serve as combined gene signatures for BD phenotype differentiation. Pathway genes comprising ATP2B4, MYOF and NRP1 for angiogenesis and GXYLT1, ENG, CD69, GAA, SIGLEC7, SIGLEC9 and SIGLEC16 for glycosylation also might be applicable diagnostic markers for subtype identification.

A Recombinant Duck Plague Virus Containing the ICP27 Deletion Marker Provides Robust Protection in Ducks. Microbiol Spectr 2023; 11:e0098323.

Abstract
Duck plague virus (DPV) is a member of Alphaherpesvirus genus and poses a major threat to waterfowl breeding. Genetic engineered vaccines that are capable of distinguishing naturally infected from vaccine-immunized animals are useful for eradicating duck plague. In this study, reverse genetics was used to develop an ICP27-deficient strain (CHv-ΔICP27), and its potential as a marker vaccination candidate was evaluated. The results showed that the CHv-ΔICP27 generated in this study exhibited good genetic stability in vitro and was highly attenuated both in vivo and in vitro. The level of neutralizing antibody generated by CHv-ΔICP27 was comparable to that induced by a commercial DPV vaccine, suggesting that it could protect ducks from virulent DPV attack. By using molecular identification techniques such as PCR, restriction fragment length polymorphism, immunofluorescence, Western blotting, and others, it is possible to differentiate the CHv-ΔICP27 from wild-type strains. Moreover, ICP27 can also be a potential target for the genetic engineering vaccine development of alphavirus or perhaps the entire herpesvirus family members due to the highly conservative of ICP27 protein in all herpesvirus family members. IMPORTANCE The development of distinguishable marker vaccines from natural infection is a key step toward eradicating duck plague. Here, we generated a recombinant DPV that carries an ICP27 deletion marker that could be easily distinguished from wild-type strain by molecular biological methods. It was highly attenuated in vitro and in vivo and could provide comparable protection to ducks after a single dose of immunizations, as commercial vaccines did. Our findings support the use of the ICP27-deficient virus as a marker vaccine for DPV control and future eradication.

Abstract
Moloney leukemia virus 10 (MOV10) is a conserved RNA helicase and has multiple biological functions in mammals, but its role remains poorly understood in bony fish. Here, we cloned a MOV10 homolog from sea perch (Lateolabrax japonicus), which contained 23 exons and 22 introns, with an open reading frame of 3000 bp encoding 1000 amino acids. Tissue distribution analysis showed that MOV10 was high expressed in blood of sea perch. Promoter analysis revealed several putative multiple transcription factors binding sites, including upstream transcription factor 1, GATA-box, transcription initiation factor IIB, activator protein 1 and two interferon (IFN) stimulated response elements. Further analysis found that IFNc, IFNh, and IFNγ could not only activate IFN regulatory factor (IRF) 1 expression which in turn led to the induction of MOV10, but also prompted the expression of IRF10 to hinder excessive MOV10 expression. Moreover, IRF2 also suppressed MOV10 expression that was initiated by IRF1. Viral hemorrhagic septicemia virus (VHSV) infection upregulated MOV10 expression in vivo and in vitro, which in turn, enhanced IFNh expression and exhibited strong antiviral activity against VHSV proliferation. This study provides a basis to investigate the immune escape of VHSV by affecting the biological function of transcription factors in the signaling pathways associated with antiviral molecules.
