    Abstract Zinc finger proteins (ZFPs) are a huge family comprised of massive, structurally diverse proteins characterized by zinc ion coordinating. They engage in the host-virus interplay in-depth and occupy a significant portion of the host antiviral arsenal. Nucleic acid-binding is the basic property of certain ZFPs, which draws increasing attention due to their immense influence on viral infections. ZFPs exert multiple roles on the viral replications and host cell transcription profiles by recognizing viral genomes and host mRNAs. Their roles could be either antiviral or proviral and were separately discussed. Our review covers the recent research progress and provides a comprehensive understanding of ZFPs in antiviral immunity based on their DNA/RNA binding property.

    Abstract Background: Arctigenin (ATG), a dibenzyl butyrolactone lignan compound, is one of the major bioactive components from the medicinal plant Arctium lappa. ATG possesses remarkable therapeutic potential against a wide range of human diseases, such as cancers, immune disorders and chronical diseases. The molecular mechanisms behind the biological effects of ATG have been intensively studied.
    Purpose: This review aims to systematically summarize the updated knowledge of the proteins and signaling pathways behind the curative property of ATG, and further analyze the potential connections between them.
    Method: SciFinder, Pubmed, Web of Science and Cochrane Library databases were queried for publications reporting the therapeutic properties of ATG. "Arctigenin", "disease", "cancer", "inflammation", "organ damage", "infection", "toxicity" and "pharmacokinetics" were used as the searching titles.
    Result: 625 publications were identified and 95 met the inclusion criteria and exclusion criteria. 42 studies described the molecular mechanisms implicated in ATG treatments. Several proteins including phosphodiesterase subtype 4D (PDE4D), estrogen receptor (ER) β, protein phosphatase 2A (PP2A), phosphoinositide 3-kinase (PI3K) and transmembrane protein 16A (TMEM16A) are targeted by ATG in different settings. The frequently described signaling pathways are TLR4/NF-κB, PI3K/AKT/mTOR, AMP-activated protein kinase (AMPK) and nuclear factor erythroid 2-related factor 2 (Nrf-2) signalings.
    Conclusion: Inhibition of PI3K/AKT pathway and activation of AMPK signaling play the pivotal roles in the therapeutic effects of ATG. PI3K/AKT and AMPK signaling widely link to other signaling pathways, modulating various biological processes such as anti-inflammation, anti-oxidative stress, anti-fibrosis, anti-ER stress, anti-steatosis and pro-apoptosis, which constitute the curative mechanisms of ATG against multiple human diseases.

    Abstract Type I interferons (IFNs) exhibit strong antiviral activity and induce the expression of antiviral proteins. Since excessive expression of type I IFNs is harmful to the host, their expression should be turned off at the appropriate time. In this study, we find that post-translational modification of LGP2, a member of the RIG-I-like receptor family, modulates antiviral innate immune responses. The LGP2 protein undergoes K63-linked polyubiquitination in response to cytoplasmic double-stranded RNAs or viral infection. Our mass spectrometry analysis reveals the K residues ubiquitinated by the Riplet ubiquitin ligase. LGP2 ubiquitination occurs with a delay compared to RIG-I ubiquitination. Interestingly, ubiquitination-defective LGP2 mutations increase the expression of type I IFN at a late phase, whereas the mutant proteins attenuate other antiviral proteins, such as SP100, PML, and ANKRD1. Our data indicate that delayed polyubiquitination of LGP2 fine-tunes RIG-I-dependent antiviral innate immune responses at a late phase of viral infection.

    Abstract RIG-I-like receptors (RLR), RIG-I and MDA5, are cytoplasmic viral RNA sensors that recognize viral double-stranded RNAs and trigger signals to induce antiviral responses, including type I interferon production. Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) caused the coronavirus disease 2019 pandemic. However, the RLR role in innate immune response to SARS-CoV-2 has not been fully elucidated. Here, we studied the roles of RLR in cytokine expression responding to SARS-CoV-2 and found that not only MDA5 but also RIG-I are involved in innate immune responses in some types of human cells. Transfection of total RNAs extracted from SARS-CoV-2-infected cells into epithelial cells induced IFN-β, IP-10, and Ccl5 mRNA expression. The cytokine expression was reduced by knockout of either RIG-I or MDA5, suggesting that both proteins are required for appropriate innate immune response to SARS-CoV-2. Two viral genomic RNA regions strongly induced type I IFN expression, and a 200-base fragment of viral RNA preferentially induced type I IFN in a RIG-I-dependent manner. In contrast, SARS-CoV-2 infectious particles hardly induced cytokine expression, suggesting viral escape from the host response. Viral 9b protein inhibited RIG-I and MAVS interaction, and viral 7a protein destabilized the TBK1 protein, leading to attenuated IRF-3 phosphorylation required for type I IFN expression. Our data elucidated the mechanism underlying RLR-mediated response to SARS-CoV-2 infection and viral escape from the host innate immune response.

  6. Article ; Online: Attenuation of the Innate Immune Response against Viral Infection Due to ZNF598-Promoted Binding of FAT10 to RIG-I.

    Abstract Excessive innate immune response is harmful to the host, and aberrant activation of the cytoplasmic viral RNA sensors RIG-I and MDA5 leads to autoimmune disorders. ZNF598 is an E3 ubiquitin ligase involved in the ribosome quality control pathway. It is also involved in the suppression of interferon (IFN)-stimulated gene (ISG) expression; however, its underlying mechanism is unclear. In this study, we show that ZNF598 is a negative regulator of the RIG-I-mediated signaling pathway, and endogenous ZNF598 protein binds to RIG-I. ZNF598 ubiquitin ligase activity is dispensable for the suppression of RIG-I signaling. Instead, ZNF598 delivers a ubiquitin-like protein FAT10 to the RIG-I protein, resulting in the inhibition of RIG-I polyubiquitination, which is required for triggering downstream signaling to produce type I IFN. Moreover, ZNF598-mediated suppression is abrogated by FAT10 knockout. Our data elucidate the mechanism by which ZNF598 inhibits RIG-I-mediated innate immune response.

    Abstract RIG-I, a cytoplasmic viral RNA sensor, is crucial for innate antiviral immune responses; however, there are controversies about the regulatory mechanism of RIG-I by several ubiquitin ligases and LGP2. This study revealed that the RIPLET ubiquitin ligase is a general activating factor for RIG-I signaling. In contrast, another ubiquitin ligase, TRIM25, activated RIG-I in a cell-type-specific manner. RIPLET and TRIM25 functions were modulated by accessory factors, such as ZCCH3C and NLRP12. Interestingly, we found an additional role of RIPLET in innate immune responses. RIPLET induced delayed polyubiquitination of LGP, resulting in the attenuation of excessive cytokine expression at the late phase. Moreover, RIPLET was involved in the innate immune responses against SARS-CoV-2 infection, a cause of the recent COVID-19 pandemic. Our data indicate that RIPLET fine-tunes innate immune responses via polyubiquitination of RIG-I and LGP2 against virus infection, including SARS-CoV-2.

    Abstract Megakaryocytes (MKs) are typical cellular components in the circulating blood flowing from the heart into the lungs. Physiologically, MKs function as an important regulator of platelet production and immunoregulation. However, dysfunction in MKs is considered a trigger in various diseases. It has been described that the lung is an important site of platelet biogenesis from extramedullary MKs, which may play an essential role in various pulmonary diseases. With detailed studies, there are different degrees of numerical changes of MKs in coronavirus disease 2019 (COVID-19), acute respiratory distress syndrome (ARDS), chronic obstructive pulmonary disease (COPD), lung cancer, pulmonary fibrosis (PF), and other pulmonary diseases. Also, MKs inhibit or promote the development of pulmonary diseases through various pathways. Here, we summarize the current knowledge of MKs in pulmonary diseases, highlighting the physiological functions and integrated molecular mechanisms. We aim to shine new light on not only the subsequent study of MKs but also the diagnosis and treatment of pulmonary diseases.
