Tracking of single virus: Dual fluorescent labeling of pseudorabies virus for observing entry and replication in the N2a cells. Vet Microbiol 2025; 304:110503.

Abstract
Pseudorabies virus (PRV) is a neurotropic herpesvirus. It is not easy to be track the whole replication progress of PRV, especially the nascent viral genome in the host cells. In this study, we developed a dual-fluorescence-labeled PRV (rPRV-Anchor3-mCherry) with the viral genome and the envelope protein gM labeled by ANCHOR DNA labeling system and mCherry, respectively. Through single-virus tracking of rPRV-Anchor3-mCherry, we observed that PRV invaded mouse neuroblastoma Neuro-2a cells via both endocytosis and plasma membrane fusion pathway. During the replication stage, parental and progeny viral genome of rPRV-Anchor3-mCherry in the cell nuclei could be visible, and viral nucleocapsid appeared more specifically than traditional capsid protein labeled PRV particles (rPRV-VP26-EGFP). We found that numerous progeny viral particles were produced in the nuclear, causing the nucleus membrane to break using three-dimensional (3D) live-cell imaging and electron microscopy. Moreover, our findings confirmed that simultaneously targeting of the UL9 and UL54 genes using a CRISPR-Cas9 system led to the complete inhibition PRV replication. rPRV-Anchor3-mCherry can be used to research multiple steps of the viral cycle.

Inhibition of the canonical Wnt/β-catenin pathway interferes with macropinocytosis to suppress pseudorabies virus proliferation. Vet Microbiol 2025; 301:110373. [PMID: 39793454 DOI: 10.1016/j.vetmic.2025.110373] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2024] [Revised: 01/03/2025] [Accepted: 01/05/2025] [Indexed: 01/13/2025]
Abstract
Pseudorabies virus (PRV) is one of the highly contagious pathogens causing significant economic losses to the swine industry worldwide. More importantly, PRV is becoming a potential "life-threatening zoonosis" since the human-originated PRV strain was first isolated in 2019. Previously we found that the canonical Wnt/β-catenin pathway facilitates PRV proliferation, while the underlying mechanism remains unknown. In this study, the antiviral activities of the Wnt inhibitors (Adavivint, CCT251545, FH535, and iCRT14) were identified. Applying these inhibitors significantly inhibited PRV proliferation in different cell lines. Among them, CCT251545 presented the strongest anti-PRV activity with IC50 values less than 200 nM. Our in vivo studies showed that treatment with CCT251545 remarkedly decreased the viral loads and protected mice challenged with PRV. Further study found that CCT251545 neither had a virucidal effect nor affected viral adsorption while mainly interfering with the entry process of the PRV life cycle. Using the FITC-dextran uptake assay, we found that CCT251545 inhibited macropinocytosis. The formation of membrane protrusions, which is important for macropinocytosis, was also inhibited by CCT251545. Consistent with this, knockout of β-catenin suppressed the PRV macropinocytosis and the formation of protrusions. On the contrary, LiCl treatment significantly stimulated the protrusion formation and the PRV entry. Together, these findings suggest that suppression of the Wnt/β-catenin pathway inhibits the macropinocytosis-dependent entry of PRV, thereby providing potential targets for developing antiviral agents against PRV.

Abstract
Foot-and-mouth disease virus (FMDV), a member of picornavirus, can enter into host cell via macropinocytosis. Although it is known that receptor tyrosine kinases (RTKs) play a crucial role in FMDV macropinocytic entry, the specific RTK responsible for regulating this process and the intricacies of RTK-mediated downstream signaling remain to be elucidated. Here, we conducted a screening of RTK inhibitors to assess their efficacy against FMDV. Our findings revealed that two compounds specifically targeting fibroblast growth factor receptor 1 (FGFR1) and FMS-like tyrosine kinase 3 (FLT3) significantly disrupted FMDV entry. Furthermore, additional evaluation through gene knockdown and overexpression confirmed the promotion effect of FGFR1 and FLT3 on FMDV entry. Interestingly, we discovered that the increasement of FMDV entry facilitated by FGFR1 and FLT3 can be ascribed to increased macropinocytic uptake. Additionally, in-depth mechanistic study demonstrated that FGFR1 interacts with FMDV VP3 and undergoes phosphorylation during FMDV entry. Furthermore, the FGFR1 inhibitor inhibited FMDV-induced activation of p21-activated kinase 1 (PAK1) on Thr212 and Thr423 sites. Consistent with these findings, the ectopic expression of FGFR1 resulted in a concomitant increase in phosphorylation level of PAK1 on Thr212 and Thr423 sites. Taken together, our findings represent the initial exploration of FGFR1's involvement in FMDV macropinocytic entry, providing novel insights with potential implications for the development of antiviral strategies.

Schisandra chinensis inhibits the entry of BoHV-1 by blocking PI3K-Akt pathway and enhances the m6A methylation of gD to inhibit the entry of progeny virus. Front Microbiol 2024; 15:1444414.

Abstract
Schisandra chinensis, a traditional Chinese medicine known for its antitussive and sedative effects, has shown promise in preventing various viral infections. Bovine herpesvirus-1 (BoHV-1) is an enveloped DNA virus that causes respiratory disease in cattle, leading to significant economic losses in the industry. Because the lack of previous reports on Schisandra chinensis resisting BoHV-1 infection, this study aimed to investigate the specific mechanisms involved. Results from TCID50, qPCR, IFA, and western blot analyses demonstrated that Schisandra chinensis could inhibit BoHV-1 entry into MDBK cells, primarily through its extract Methylgomisin O (Meth O). The specific mechanism involved Meth O blocking BoHV-1 entry into cells via clathrin- and caveolin-mediated endocytosis by suppressing the activation of PI3K-Akt signaling pathway. Additionally, findings from TCID50, qPCR, co-immunoprecipitation and western blot assays revealed that Schisandra chinensis blocked BoHV-1 gD transcription through enhancing m6A methylation of gD after virus entry, thereby hindering gD protein expression and preventing progeny virus entry into cells and ultimately inhibiting BoHV-1 replication. Overall, these results suggest that Schisandra chinensis can resist BoHV-1 infection by targeting the PI3K-Akt signaling pathway and inhibiting gD transcription.

Abstract
Living viruses characterized by distinctive biological functions including specific targeting, gene invasion, immune modulation, and so forth have been receiving intensive attention from researchers worldwide owing to their promising potential for producing numerous theranostic modalities against diverse pathological conditions. Nevertheless, concerns during applications, such as rapid immune clearance, altering immune activation modes, insufficient gene transduction efficiency, and so forth, highlight the crucial issues of excessive therapeutic doses and the associated biosafety risks. To address these concerns, synthetic nanomaterials featuring unique physical/chemical properties are frequently exploited as efficient drug delivery vehicles or treatments in biomedical domains. By constant endeavor, researchers nowadays can create adaptable living virus-based nanohybrids (LVN) that not only overcome the limitations of virotherapy, but also combine the benefits of natural substances and nanotechnology to produce novel and promising therapeutic and diagnostic agents. In this review, we discuss the fundamental physiochemical properties of the viruses, and briefly outline the basic construction methodologies of LVN. We then emphasize their distinct diagnostic and therapeutic performances for various diseases. Furthermore, we survey the foreseeable challenges and future perspectives in this interdisciplinary area to offer insights. This article is categorized under: Biology-Inspired Nanomaterials > Protein and Virus-Based Structures Therapeutic Approaches and Drug Discovery > Emerging Technologies.

Abstract
Bovine herpesvirus-1 (BoHV-1) can infect all breeds of cattle and cause severe respiratory organs and genital tract diseases. However, the mechanism of BoHV-1 entering the cells remains unclear. In this study, we explored the mechanism of BoHV-1 entering MDBK cells. We found that the entry of BoHV-1 was blocked by NH4Cl and bafilomycin A1, indicating that BoHV-1 entry is dependent on the acidic environment of endosome. Specific inhibitor dynasore and small interfering RNA (siRNA) knockdown of dynamin-2 inhibited BoHV-1 entry, showing that dynamin is required in BoHV-1 entry. The results of specific inhibitor, siRNA knockdown and co-localization indicating clathrin- and caveolin- mediated endocytosis play a role in BoHV-1 entry. BoHV-1 infection was not affected by EIPA which is a specific inhibitor of macropinocytosis. In addition, we found that BoHV-1 triggered PI3K-Akt-NF-κB and Ras-p38 MAPK signaling pathways to induce clathrin-mediated and caveolin-mediated endocytosis at the early stage of BoHV-1 infection. BoHV-1 binding was sufficient to activate the endocytic signaling pathways and promote viral entry. These two signaling pathways were activated by transfection of viral gD protein, and were inhibited by deletion of viral gD protein and the siRNA knockdown of cellular receptor nectin-1. The results of co-localization indicating the entered BoHV-1 is traced to late endosomes via early endosomes. Our results suggested the interaction of viral gD protein and cellular receptor nectin-1 triggered the PI3K-Akt-NF-κB and Ras-p38 MAPK signaling pathways and induced clathrin-mediated and caveolin-mediated endocytosis to promote BoHV-1 entry into MDBK cells at the early stage of BoHV-1 infection.

J Biol Chem 2023; 299:104605. [PMID: 36918100 PMCID: PMC10140166 DOI: 10.1016/j.jbc.2023.104605] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2022] [Revised: 03/06/2023] [Accepted: 03/07/2023] [Indexed: 03/14/2023] Open
Abstract
Pseudorabies virus (PRV) has become a "new life-threatening zoonosis" since the human-originated PRV strain was first isolated in 2020. To identify novel anti-PRV agents, we screened a total of 107 β-carboline derivatives and found 20 compounds displaying antiviral activity against PRV. Among them, 14 compounds showed better antiviral activity than acyclovir. We found that compound 45 exhibited the strongest anti-PRV activity with an IC50 value of less than 40 nM. Our in vivo studies showed that treatment with 45 significantly reduced the viral loads and protected mice challenged with PRV. To clarify the mode of action of 45, we conducted a time of addition assay, an adsorption assay, and an entry assay. Our results indicated that 45 neither had a virucidal effect nor affected viral adsorption while significantly inhibiting PRV entry. Using the FITC-dextran uptake assay, we determined that 45 inhibits macropinocytosis. The actin-dependent plasma membrane protrusion, which is important for macropinocytosis, was also suppressed by 45. Further, the kinase DYRK1A was predicted to be a potential target for 45. The binding of 45 to DYRK1A was confirmed by DARTS and CETSA. Further analysis revealed that knockdown of DYRK1A by siRNA suppressed PRV macropinocytosis and the TNFα-induced formation of protrusions. These results suggested that 45 could restrain PRV macropinocytosis by targeting DYRK1A. Together, these findings reveal a unique mechanism through which β-carboline derivatives restrain PRV infection, pointing to their potential value in the development of anti-PRV agents. Our data also reveal a potential target for designing novel macropinocytosis inhibitors.

Abstract
Single-virus tracking (SVT) offers the opportunity to monitor the journey of individual viruses in real time and to explore the interactions between viral and cellular structures in live cells, which can assist in characterizing the complex infection process and revealing the associated dynamic mechanisms. However, the low brightness and poor photostability of conventional fluorescent tags (e.g., organic dyes and fluorescent proteins) greatly limit the development of the SVT technique, and challenges remain in performing multicolor SVT over long periods of time. Owing to the outstanding photostability, high brightness and narrow emission with tunable color range of quantum dots (QDs), QD-based SVT (QSVT) enables us to follow the fate of individual viruses interacting with different cellular structures at the single-virus level for milliseconds to hours, providing more accurate and detailed information regarding viral infection in live cells. So far, the QSVT technique has yielded spectacular achievements in uncovering the mechanisms associated with virus entry, trafficking and egress. Here, we provide a detailed protocol for QSVT implementation using the viruses that we have previously studied systematically as an example. The specific procedures for performing QSVT experiments in live cells are described, including virus preparation, the QD labeling strategies, imaging approaches, image processing and data analysis. The protocol takes 1-2 weeks from the preparation of viruses and cellular specimens to image acquisition, and 1 d for image processing and data analysis.

Abstract
Targeted cancer therapy has aroused the broad interest of researchers due to its accuracy in specific tumor targeting and its few side effects on normal cells. In the last decades, oncolytic viral light particles (L-particles) have been transformed into smart nanocarriers for targeted drug delivery. However, these L-particles, similar to the oncolytic viruses that they are derived from, can only recognize tumor cells expressing corresponding receptors, severely limiting their universal application. Although modification of targeting agents onto their envelope can overcome this limitation, it is still a great challenge to do so without interfering with their biofunction since the envelope is fragile. Herein, a host-cell-assisted strategy is proposed to construct folate-engineered nanocarriers (F-L-particles) with their biofunctions maintained to the largest extent. The F-L-particles were further multi-functionalized by encapsulating ultrasmall near-infrared quantum dots and antitumor drugs in them for tumor real-time imaging and therapy. Such a moderate, efficient and convenient cell-based strategy facilitates the development and widespread application of these bio-nanocarriers in the field of targeted cancer therapy, and drives the interdisciplinary studies of nanotechnology, chemistry, and virology.

Abstract
Canid herpesvirus 1 (CHV-1) is a Varicellovirus that causes self-limiting infections in adult dogs but morbidity and mortality in puppies. Using a multipronged approach, we discovered the CHV-1 entry pathway into Madin-Darby canine kidney (MDCK) epithelial cells. We found that CHV-1 triggered extensive host cell membrane lamellipodial ruffling and rapid internalisation of virions in large, uncoated vacuoles, suggestive of macropinocytosis. Treatment with inhibitors targeting key macropinocytosis factors, including inhibitors of Na+ /H+ exchangers, F-actin, myosin light-chain kinase, protein kinase C, p21-activated kinase, phosphatidylinositol-3-kinase and focal adhesion kinase, significantly reduced viral replication. Moreover, the effect was restricted to exposure to the inhibitors early in infection, confirming a role for the macropinocytic machinery during entry. The profile of inhibitors also suggested a role for signalling via integrins and receptor tyrosine kinases in viral entry. In contrast, inhibitors of clathrin, caveolin, microtubules and endosomal acidification did not affect CHV-1 entry into MDCK cells. We found that the virus colocalised with the fluid-phase uptake marker dextran; however, surprisingly, CHV-1 infection did not enhance the uptake of dextran. Thus, our results indicate that CHV-1 uses a macropinocytosis-like, pH-independent entry pathway into MDCK cells, which nevertheless is not based on stimulation of fluid uptake. TAKE AWAYS: CHV-1 enters epithelial cells via a macropinocytosis-like mechanism. CHV-1 induces extensive lamellipodial ruffling. CHV-1 entry into MDCK cells is pH-independent.

Abstract
Recent research has highlighted the immense potential of the quantum dot (QD)-based single-virus tracking (SVT) technique in virology. In these experiments, the infection behaviors of single viruses or viral components, labeled with QDs, could be tracked on time scales of milliseconds to hours in host cells. The trajectories of individual viruses are reconstructed with nanometer accuracy, and the underlying dynamic information on virus infection can be extracted to uncover the infection mechanisms of viruses. Therefore, QD-based single-virus tracking (QSVT) is an exquisitely selective and powerful approach to investigating how viruses are internalized in host cells dynamically to release their genome for viral replication and assembly that ensure the completion of viral life cycles.QDs are better candidates than organic dyes and fluorescent proteins for virus labeling and subsequent SVT due to the following considerations: (i) the high brightness of QDs makes it possible to label a virus with sufficient brightness using very few QDs or even just one QD; (ii) the extraordinary photostability of QDs allows one to track the infection process long term and quantify low probability events; (iii) the color-tunable emission property of QDs ensures multicolor labeling of various components of a virus simultaneously; and (iv) the abundant surface ligands of QDs facilitate the conjugation of a virus with a variety of labeling strategies. Therefore, the photoproperties of QDs make it possible to perform multicolor long-term SVT experiments quantitatively. Nowadays, the QD-based SVT (QSVT) technique has made prodigious achievements in unraveling the entry, trafficking, and uncoating mechanisms of viruses. This fascinating technique can provide spatiotemporal dynamic information on the viral journey in unprecedented detail and has revolutionized our understanding of virus infection.In this Account, we first introduce the advantages and the limitations of conventional SVT in virological research and the unique features of QDs as labels in the SVT field. We subsequently focus on the principles and related methods of QSVT and the current state of QD chemistry and QD-based virus labeling that resolves many issues associated with the tracking of individual viruses in live cells. Then we emphasize some new findings by this technique in the study of infection mechanisms. Finally, we will provide our insights into future challenges on this topic. With this Account, we hope to further stimulate the development of QSVT with a combined effort from different disciplines and, more importantly, to accelerate the applications of QSVT in virological research.

Abstract
Viruses utilize host cell signaling to facilitate productive infection. Equine herpesvirus type 1 (EHV-1) has been shown to activate Ca2+ release and phospholipase C upon contact with α4β1 integrins on the cell surface. Signaling molecules, including small GTPases, have been shown to be activated downstream of Ca2+ release, and modulate virus entry, membrane remodeling and intracellular transport. In this study, we show that EHV-1 activates the small GTPases Rac1 and Cdc42 during infection. The activation of Rac1 and Cdc42 is necessary for virus-induced acetylation of tubulin, effective viral transport to the nucleus, and cell-to-cell spread. We also show that inhibitors of Rac1 and Cdc42 did not block virus entry, but inhibited overall virus infection. The Rac1 and Cdc42 signaling is presumably orthogonal to Ca2+ release, since Rac1 and Cdc42 inhibitors affected the infection of both EHV-1 and EHV-4, which do not bind to integrins.

Abstract
Labeling viruses with high-photoluminescence quantum dots (QDs) for single virus tracking provides a visual tool to aid our understanding of viral infection mechanisms. However, efficiently labeling internal viral components without modifying the viral envelope and capsid remains a challenge, and existing strategies are not applicable to most viruses. Here, we have devised a strategy using the clustered regularly interspaced short palindromic repeats (CRISPR) imaging system to label the nucleic acids of Pseudorabies virus (PRV) with QDs. In this strategy, QDs were conjugated to viral nucleic acids with the help of nuclease-deactivated Cas9/gRNA complexes in the nuclei of living cells and then packaged into PRV during virion assembly. The processes of PRV-QD adsorption, cytoplasmic transport along microtubules, and nuclear entry were monitored in real time in both Vero and HeLa cells, demonstrating the utility and efficiency of the strategy in the study of viral infection.

Abstract
Nanosized oncolytic viral light particles (L-particles), separated from progeny virions, are composed of envelopes and several tegument proteins of viruses, free of nucleocapsids. The noninfectious L-particles experience the same internalization process as mature oncolytic virions, which exhibits great potential to act as targeted therapeutic platforms. However, the clinical applications of L-particle-based theranostic platforms are rare due to the lack of effective methods to transform L-particles into nanovectors. Herein, a convenient and mild strategy has been developed to transform L-particles into near-infrared (NIR) fluorescence Ag2Se quantum dot (QD)-labeled active tumor-targeting nanovectors for real-time in situ imaging and drug delivery. Utilizing the electroporation technique, L-particles can be labeled with ultrasmall water-dispersible NIR fluorescence Ag2Se QDs with a labeling efficiency of ca. 85% and loaded with antitumor drug with a loading efficiency of ca. 87%. Meanwhile, by harnessing the infection mechanism of viruses, viral L-particles are able to recognize and enter tumor cells without further modification. In sum, a trackable and actively tumor-targeted theranostics nanovector can be obtained efficiently and simultaneously. Such multifunctional nanovectors transformed from viral L-particles have exhibited excellent properties of active tumor-targeting, in vivo tumor imaging, and antitumor efficacy, which opens a new window for the development of natural therapeutic nanoplatforms.
