MARCH6 suppresses Tembusu virus replication by targeting viral NS5 protein for TOLLIP-mediated selective autophagic degradation

Journal of Virology
The E3 ligase membrane-associated RING finger 6 (MARCH6) plays a pivotal role in various cellular processes; however, its role in viral defense remains largely unexplored.

CHB‐Induced Immune Zonation Chaos Elicited LXRα‐mediated Lipid Metabolism Disorders in Kupffer Cells to Induce Cancer Stem Cell Formation

Advanced Science, EarlyView.
By profiling the spatiotemporal hepatic landscape of CHB mouse models, the originally peri‐portal localized KCs migrated to the peri‐central in a CXCL9‐CXCR3‐dependent manner, facilitating their interaction with HBV+ hepatocytes. The interaction promoted LMD in KCs through ASGR1‐induced LXRα degradation, which, in turn, induced CSC formation via Stat3 ...

A Lung‐Immune Dual‐Humanized Mouse Using Cryopreserved Tissue Enables Infection and Immune Profiling of Human Common Cold Coronaviruses

Advanced Science, EarlyView.
Cryopreserved lung‐humanized mice overcome the dependency to fresh tissues and permit head‐to‐head profiling of all four human common cold coronaviruses versus SARS‐CoV‐2 infection; the model validates Paxlovid efficacy against HKU1 and, when coupled with human immune‐system engraftment, enables interrogation of lung‐resident human immunity and HKU1 ...

A dsRNA Viral Transcriptional Regulator Evades Innate Immunity by Hijacking Host CoTranscription Factor DHX9

Advanced Science, EarlyView.
This study identifies a new viral mechanism by a viral protein σ3 that functions as a vTR to suppress NF‐κB gene expression via its direct interaction with the host helicase DHX9. Through their interaction, σ3 not only impairs the initial recruitment of Pol II but also affects Pol II pause‐release and ultimately suppresses NF‐κB gene expression ...

Type III Interferons in Viral Infection and Antiviral Immunity

Cellular Physiology and Biochemistry, 2018
Interferons (IFNs) can serve as the first line of immune defense against viral infection. The identification of IFN-λs 1, 2, 3 & 4 (termed as type III IFNs) has revealed that the antiviral immune response to viruses contains more components than the ...

TRIM38 Suppresses Breast Cancer Progression via Modulating SQSTM1 Ubiquitination and Autophagic Flux

Advanced Science, EarlyView.
TRIM38, an E3 ubiquitin ligase, suppresses breast cancer progression by inhibiting proliferation, migration, and invasion. Downregulated in breast tumor, its loss correlates with poor prognosis. Mechanistically, TRIM38 mediates K63‐linked ubiquitination of SQSTM1/p62 at K420, disrupting SQSTM1‐LC3 interaction and blocking autophagic flux.

Decreased SynMuv B gene activity in response to viral infection leads to activation of the antiviral RNAi pathway in C. elegans.

PLoS Biology
RNA interference (RNAi) mediates antiviral defense in many eukaryotes. Caenorhabditis elegans mutants that disable RNAi are more sensitive to viral infection. Many mutants that enhance RNAi have also been identified; these mutations may reveal genes that

Antiviral defense in salmonids – Mission made possible?

Fish & Shellfish Immunology, 2019
Viral diseases represent one of the major threats for salmonid aquaculture. Survival from viral infections are highly dependent on host innate antiviral immune defense, where interferons are of crucial importance. Neutralizing antibodies and T cell effector mechanisms mediate long-term antiviral protection.

Host‐Directed Antiviral Activity of SB2960 Through Selective Induction and Remodeling of Stress Granules

Advanced Science, EarlyView.
Amid the ongoing threat of emerging viral pathogens, host‐directed antivirals offer a strategy to overcome viral mutation and drug resistance. SB2960, a small‐molecule inducer of stress granules (SGs), exhibits potent broad‐spectrum antiviral activity with minimal cytotoxicity.

Mechanisms of virus resistance and antiviral activity of snake venoms

Journal of Venomous Animals and Toxins including Tropical Diseases, 2011
Viruses depend on cell metabolism for their own propagation. The need to foster an intimate relationship with the host has resulted in the development of various strategies designed to help virus escape from the defense mechanisms present in the host ...
