Roe K. Deadly interactions: Synergistic manipulations of concurrent pathogen infections potentially enabling future pandemics. Drug Discov Today 2023; 28:103762. [PMID: 37660981 DOI: 10.1016/j.drudis.2023.103762] [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: 06/08/2023] [Revised: 08/18/2023] [Accepted: 08/29/2023] [Indexed: 09/05/2023]
Abstract
Certain mono-infections of influenza viruses and novel coronaviruses, including severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2) are significant threats to human health. Concurrent infections by influenza viruses and coronaviruses increases their danger. Influenza viruses have eight manipulations capable of assisting SARS-CoV-2 and other coronaviruses, and several of these manipulations, which are not specific to viruses, can also directly or indirectly boost dangerous secondary bacterial pneumonias. The influenza virus manipulations include: inhibiting transcription factors and cytokine expression; impairing defensive protein expression; increasing RNA viral replication; inhibiting defenses by manipulating cellular sensors and signaling pathways; inhibiting defenses by secreting exosomes; stimulating cholesterol production to increase synthesized virion infectivities; increasing cellular autophagy to assist viral replication; and stimulating glucocorticoid synthesis to suppress innate and adaptive immune defenses by inhibiting cytokine, chemokine, and adhesion molecule production. Teaser: Rapidly spreading multidrug-resistant respiratory bacteria, combined with influenza virus's far-reaching cellular defense manipulations benefiting evolving SARS-CoV-2 or other coronaviruses and/or respiratory bacteria, can enable more severe pandemics or co-pandemics.

Roe K. Increased Fungal Infection Mortality Induced by Concurrent Viral Cellular Manipulations. Lung 2023; 201:467-476.

Abstract
Certain respiratory fungal pathogen mono-infections can cause high mortality rates. Several viral pathogen mono-infections, including influenza viruses and coronaviruses including SARS-CoV-2, can also cause high mortality rates. Concurrent infections by fungal pathogens and highly manipulative viral pathogens can synergistically interact in the respiratory tract to substantially increase their mortality rates. There are at least five viral manipulations which can assist secondary fungal infections. These viral manipulations include the following: (1) inhibiting transcription factors and cytokine expressions, (2) impairing defensive protein expressions, (3) inhibiting defenses by manipulating cellular sensors and signaling pathways, (4) inhibiting defenses by secreting exosomes, and (5) stimulating glucocorticoid synthesis to suppress immune defenses by inhibiting cytokine, chemokine, and adhesion molecule production. The highest mortality respiratory viral pandemics up to now have had substantially boosted mortalities by inducing secondary bacterial pneumonias. However, numerous animal species besides humans are also carriers of endemic infections by viral and multidrug-resistant fungal pathogens. The vast multi-species scope of endemic infection opportunities make it plausible that the pro-fungal manipulations of a respiratory virus can someday evolve to enable a very high mortality rate viral pandemic inducing multidrug-resistant secondary fungal pathogen infections. Since such pandemics can quickly spread world-wide and outrun existing treatments, it would be worthwhile to develop new antifungal treatments well before such a high mortality event occurs.

Cell Mol Immunol 2023; 20:1186-1202. [PMID: 37582970 PMCID: PMC10542333 DOI: 10.1038/s41423-023-01065-2] [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: 03/14/2023] [Accepted: 07/05/2023] [Indexed: 08/17/2023] Open
Abstract
The adaptor molecule MAVS forms prion-like aggregates to govern the RIG-I-like receptor (RLR) signaling cascade. Lys63 (K63)-linked polyubiquitination is critical for MAVS aggregation, yet the underlying mechanism and the corresponding E3 ligases and deubiquitinating enzymes (DUBs) remain elusive. Here, we found that the K63-linked polyubiquitin chains loaded on MAVS can be directly recognized by RIG-I to initiate RIG-I-mediated MAVS aggregation with the prerequisite of the CARDRIG-I-CARDMAVS interaction. Interestingly, many K63-linked polyubiquitin chains attach to MAVS via an unanchored linkage. We identified Ube2N as a major ubiquitin-conjugating enzyme for MAVS and revealed that Ube2N cooperates with the E3 ligase Riplet and TRIM31 to promote the unanchored K63-linked polyubiquitination of MAVS. In addition, we identified USP10 as a direct DUB that removes unanchored K63-linked polyubiquitin chains from MAVS. Consistently, USP10 attenuates RIG-I-mediated MAVS aggregation and the production of type I interferon. Mice with a deficiency in USP10 show more potent resistance to RNA virus infection. Our work proposes a previously unknown mechanism for the activation of the RLR signaling cascade triggered by MAVS-attached unanchored K63-linked polyubiquitin chains and establishes the DUB USP10 and the E2:E3 pair Ube2N-Riplet/TRIM31 as a specific regulatory system for the unanchored K63-linked ubiquitination and aggregation of MAVS upon viral infection.

[PMID: 37759744 PMCID: PMC10526236 DOI: 10.3390/biom13091344] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2023] [Revised: 08/30/2023] [Accepted: 08/30/2023] [Indexed: 09/29/2023] Open
Abstract
The retinoic acid-inducible gene I (RIG-I)-like receptors (RLRs) play a crucial role as pattern-recognition receptors within the innate immune system. These receptors, present in various cell and tissue types, serve as essential sensors for viral infections, enhancing the immune system's capacity to combat infections through the induction of type I interferons (IFN-I) and inflammatory cytokines. RLRs are involved in a variety of physiological and pathological processes, including viral infections, autoimmune disorders, and cancer. An increasing body of research has examined the possibility of RLRs or microRNAs as therapeutic targets for antiviral infections and malignancies, despite the fact that few studies have focused on the regulatory function of microRNAs on RLR signaling. Consequently, our main emphasis in this review is on elucidating the role of microRNAs in modulating the signaling pathways of RLRs in the context of cancer and viral infections. The aim is to establish a robust knowledge base that can serve as a basis for future comprehensive investigations into the interplay between microRNAs and RIG-I, while also facilitating the advancement of therapeutic drug development.

Poult Sci 2023; 102:102890. [PMID: 37441905 PMCID: PMC10362356 DOI: 10.1016/j.psj.2023.102890] [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: 04/14/2023] [Revised: 06/12/2023] [Accepted: 06/17/2023] [Indexed: 07/15/2023] Open
Abstract
Duck Tembusu virus (DTMUV), belonging to the Flaviviridae family, is a major virus that affects duck health in China. MicroRNAs (miRNAs) play an important role in viral replication. However, little is known about the function of miRNAs during DTMUV infection. Here, the host miR-146b-5p was found to regulate DTMUV replication. When DTMUV infected duck embryo fibroblasts (DEFs), the expression levels of miR-146b-5p increased significantly over time. Moreover, the viral RNA copies, E protein expression levels and virus titers were all upregulated when miR-146b-5p was overexpressed in DEFs. The opposite results were also observed upon knockdown of miR-146b-5p in DEFs. To explore the mechanism by which miR-146b-5p promoted DTMUV replication, mass spectrometry, and RNA pull-down assays were employed. Ribosomal protein S14 (RPS14), a component of 40S ribosomal proteins, was identified to interact with miR-146b-5p. In addition, the relative mRNA expression levels of RPS14 gene were negatively modulated by miR-146b-5p. Subsequently, it was found that overexpression of RPS14 could decrease the replication of DTMUV, and the reverse results were also detected by knockdown of RPS14. In conclusion, this study revealed that miR-146b-5p promoted DTMUV replication by targeting RPS14, which provides a new mechanism by which DTMUV evades host defenses and a new direction for further antiviral strategies development.

Abstract
Viral pathogens in the lungs can cause severe outcomes, including acute lung injury and acute respiratory distress syndrome. Dangerous respiratory pathogens include some influenza A and B viruses, and the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Unfortunately, concurrent infections of influenza virus and SARS-CoV-2 increase severe outcome probabilities. Influenza viruses have eight cellular manipulations which can assist concurrent SARS-CoV-2 viral infections. The eight cellular manipulations include: (1) viral protein binding with cellular sensors to block antiviral transcription factors and cytokine expressions, (2) viral protein binding with cell proteins to impair cellular pre-messenger ribonucleic acid splicing, (3) increased ribonucleic acid virus replication through the phosphatidylinositol 3-kinase/Akt (protein kinase B) pathway, (4) regulatory ribonucleic acids to manipulate cellular sensors and pathways to suppress antiviral defenses, (5) exosomes to transmit influenza virus to uninfected cells to weaken cellular defenses before SARS-CoV-2 infection, (6) increased cellular cholesterol and lipids to improve virion synthesis stability, quality and virion infectivity, (7) increased cellular autophagy, benefiting influenza virus and SARS-CoV-2 replications and (8) adrenal gland stimulation to produce glucocorticoids, which suppress immune cells, including reduced synthesis of cytokines, chemokines and adhesion molecules. Concurrent infections by one of the influenza viruses and SARS-CoV-2 will increase the probability of severe outcomes, and with sufficient synergy potentially enable the recurrence of tragic pandemics.

Abstract
The host innate immune system's defense against viral infections depends heavily on type I interferon (IFN-I) production. Research into the mechanisms of virus-host interactions is essential for developing novel antiviral therapies. In this study, we compared the effect of the five members of the microRNA-200 (miR-200) family on IFN-I production during viral infection and found that miR-200b-3p displayed the most pronounced regulatory effect. During viral infection, we discovered that the transcriptional level of microRNA-200b-3p (miR-200b-3p) increased with the infection of influenza virus (IAV) and vesicular stomatitis virus (VSV), and miR-200b-3p production was modulated by the activation of the ERK and p38 pathways. We identified cAMP response element binding protein (CREB) as a novel transcription factor that binds to the miR-200b-3p promoter. MiR-200b-3p reduces NF-κB and IRF3-mediated IFN-I production by targeting the 3' untranslated region (3' UTR) of TBK1 mRNA. Applying miR-200b-3p inhibitor enhances IFN-I production in IAV and VSV-infected mouse models, thus inhibiting viral replication and improving mouse survival ratio. Importantly, in addition to IAV and VSV, miR-200b-3p inhibitors exhibited potent antiviral effects against multiple pathogenic viruses threatening human health worldwide. Overall, our study suggests that miR-200b-3p might be a potential therapeutic target for broad-spectrum antiviral therapy. IMPORTANCE The innate immune response mediated by type I interferon (IFN-I) is essential for controlling viral replication. MicroRNAs (miRNAs) have been found to regulate the IFN signaling pathway. In this study, we describe a novel function of miRNA-200b-3p in negatively regulating IFN-I production during viral infection. miRNA-200b-3p was upregulated by the MAPK pathway activated by IAV and VSV infection. The binding of miRNA-200b-3p to the 3' UTR of TBK1 mRNA reduced IFN-I activation mediated by IRF3 and NF-κB. Application of miR-200b-3p inhibitors exhibited potent antiviral effects against multiple RNA and DNA viruses. These results provide fresh insight into understanding the impact of miRNAs on host-virus interactions and reveal a potential therapeutic target for common antiviral intervention.

Transforming acidic coiled-coil containing protein 3 suppresses influenza A virus replication by impeding viral endosomal trafficking and nuclear import. Vet Microbiol 2023; 282:109769.

Abstract
Transforming acidic coiled-coil containing protein 3 (TACC3) is a motor spindle protein that plays an essential role in stabilization of the mitotic spindle. In this study, we show that the overexpression of TACC3 reduces the viral titers of multiple influenza A viruses (IAVs). In contrast, the downregulation of TACC3 increases IAVs propagation. Next, we map the target steps of TACC3 requirement to the early stages of viral replication. By confocal microscopy and nuclear plasma separation experiment, we reveal that overexpression of TACC3 results in a substantial decrease of IAV NP accumulation in the nuclei of infected cells. We further show that viral attachment and internalization are not affected by TACC3 overexpression and detect that the early and late endosomal trafficking of IAV in TACC3 overexpression cells is slower than negative control cells. These results suggest that TACC3 exerts an impaired effect on the endosomal trafficking and nuclear import of vRNP, thereby negatively regulating IAV replication. Moreover, the infection of different IAV subtypes decreases the expression level of TACC3 in turn. Consequently, we speculate that IAV ensures the generation of offspring virions by antagonizing the expression of inhibitory factor TACC3. Collectively, our results establish TACC3 as an important inhibitory factor for replication of the IAV, suggesting that TACC3 could be a potential target for the development of future antiviral compounds.

Abstract
BACKGROUND Pathological cardiac hypertrophy can lead to heart failure and is one of the leading causes of death globally. Understanding the molecular mechanism of pathological cardiac hypertrophy will contribute to the treatment of heart failure. DUBs (deubiquitinating enzymes) are essential to cardiac pathophysiology by precisely controlling protein function, localization, and degradation. This study set out to investigate the role and molecular mechanism of a DUB, USP25 (ubiquitin-specific peptidase 25), in pathological cardiac hypertrophy. METHODS The role of USP25 in myocardial hypertrophy was evaluated in murine cardiomyocytes in response to Ang II (angiotensin II) and transverse aortic constriction stimulation and in hypertrophic myocardium tissues of heart failure patients. Liquid chromotography with mass spectrometry/mass spectrometry analysis combined with Co-IP was used to identify SERCA2a (sarcoplasmic/endoplasmic reticulum Ca2+-ATPase 2A), an antihypertrophy protein, as an interacting protein of USP25. To clarify the molecular mechanism of USP25 in the regulation of SERCA2a, we constructed a series of mutant plasmids of USP25. In addition, we overexpressed USP25 and SERCA2a in the heart with adenoassociated virus serotype 9 vectors to validate the biological function of USP25 and SERCA2a interaction. RESULTS We revealed increased protein level of USP25 in murine cardiomyocytes subject to Ang II and transverse aortic constriction stimulation and in hypertrophic myocardium tissues of patients with heart failure. USP25 deficiency aggravated cardiac hypertrophy and cardiac dysfunction under Ang II and transverse aortic constriction treatment. Mechanistically, USP25 bound to SERCA2a directly via its USP (ubiquitin-specific protease) domain and cysteine at position 178 of USP25 exerts deubiquitination to maintain the stability of the SERCA2a protein by removing the K48 ubiquitin chain and preventing proteasomal pathway degradation, thereby maintaining calcium handling in cardiomyocytes. Moreover, restoration of USP25 expression via adenoassociated virus serotype 9 vectors in USP25-/- mice attenuated Ang II-induced cardiac hypertrophy and cardiac dysfunction, whereas myocardial overexpression of SERCA2a could mimic the effect of USP25. CONCLUSIONS We confirmed that USP25 inhibited cardiac hypertrophy by deubiquitinating and stabilizing SERCA2a.

Abstract
Influenza A virus (IAV) infection has traditionally been a serious problem in animal husbandry and human public health security. Recently, many studies identified that long noncoding RNAs play an important role in the antiviral immune response after the infection of the influenza virus. However, there are still lots of IAV-related lncRNAs that have not been well-characterized. Using RNA sequencing analysis, we identified a lncRNA, named Serpina3i Activation Associated lncRNA (SAAL), which can be significantly upregulated in mice after IAV infection. In this study, we found that overexpression of SAAL inhibited the replication of A/WSN/33(WSN). SAAL upregulated Serpina3i with or without WSN infection. Overexpression of Serpina3i reduced influenza virus infection. Meanwhile, knockdown of Serpina3i enhanced the replication of WSN. Furthermore, knockdown of Serpina3i abolished the SAAL-mediated decrease in WSN infection. Overexpression of SAAL or Serpina3i positively regulated the transcription of interferon β (IFN-β) and several critical ISGs after WSN infection. In conclusion, we found that the novel lncRNA SAAL is a critical anti-influenza regulator by upregulating the mRNA level of Serpina3i.

Specific Monoclonal Antibodies Targeting Unique HA Epitopes Block H7N9 Influenza A Viral Replication. J Virol 2022; 96:e0123822.

Abstract
The H7N9 subtype influenza A viruses pose a serious threat to public health, and there is still a lack of vaccines or drugs for humans against H7N9 influenza viruses. In this study, we screened two monoclonal antibodies (MAbs), 4H1E8 and 7H9A6, that specifically recognize the hemagglutinin (HA) protein of H7N9 influenza virus and display highly neutralizing activity against H7N9 virus. The epitopes recognized by two MAbs are nearly all conserved within all known H7 subtypes. Characteristic identification showed that two MAbs have high avidity for the HA protein but no hemagglutinin inhibition activity or antibody-dependent cellular cytotoxicity. Mechanistically, the 4H1E8 and 7H9A6 antibodies inhibit the pH-dependent conformational change of HA and block the HA-mediated membrane fusion. More importantly, 4H1E8 and 7H9A6 exhibit promising prophylactic and therapeutic effects against lethal challenge with H7N9 virus. Moreover, 4H1E8- and 7H9A6-treated mice displayed inhibition of pulmonary viral replication and reduced lung lesions after viral challenge. Together, these findings indicate that antibodies 4H1E8 and 7H9A6 recognize unique epitopes in the HA protein and possess the neutralizing activity and protective efficacy against the H7N9 influenza A viruses. IMPORTANCE In 2013, H7N9 influenza viruses appeared in China and other countries resulting in more than 1,500 individual infections or death. There are still limited studies on vaccines or drugs for humans against H7N9 influenza viruses. Alternative approaches against H7N9 virus infection need to be developed. Here, we identified two monoclonal antibodies (4H1E8 and 7H9A6) that possess neutralizing activity by blocking the pH-dependent HA-mediated membrane fusion. Additionally, the two monoclonal antibodies protect mice against the H7N9 virus challenge prophylactically or therapeutically. Therefore, our study demonstrates that 4H1E8 and 7H9A6 could be used for the prevention and treatment of the H7N9 influenza virus, and the conserved epitopes we identified may contribute to the development of a broad H7N9 vaccine and provide insights into unique antiviral approaches.
