MetabolomicsProkaryotic viperins produce diverse antiviral molecules
Viperin is an interferon-induced cellular protein conserved in animals. It was shown to inhibit the replication of multiple viruses by producing a ribonucleotide called 3’-deoxy-3’4’-didehydro-CTP (ddhCTP), which acts as a chain terminator for the viral RNA polymerase. Here we show that the eukaryot...

MetabolomicsExercise Activates Interferon Immune Response of the Liver via Gpld1 to Enhance Antiviral Innate Immunity

Healthy behavioral patterns could modulate organ functions to enhance the body’s immunity. However, whether exercise regulates antiviral innate immunity remains elusive. Here, we found that exercise promotes type-I IFN (IFN-I) production in the liver and enhances IFN-I immune activity of the body...

MetabolomicsPhosphoethanolamine Cytidylyltransferase 2 Integrates DAG Metabolism and TBK1 Activation to Regulate Antiviral Innate Immunity

Phosphatidylethanolamine (PE) biosynthesis is critical for membrane biology and cellular homeostasis. However, its specific role in antiviral innate immunity remains poorly understood. Here, we demonstrate that inhibition of phosphoethanolamine cytidylyltransferase 2 (PCYT2), a key enzyme in...

MetabolomicsPlasma Metabolome Analysis for Predicting Antiviral Treatment Efficacy in Chronic Hepatitis B: Diagnostic Biomarkers and Therapeutic Insights
The early and accurate identification of predictive biomarkers for antiviral treatment efficacy remains a significant clinical challenge, particularly in the management of chronic hepatitis B (CHB). This study aimed to assess whether the plasma metabolome could reliably predict the success of antivi...

MetabolomicsViral-Induced Heme Accumulation Subverts TLR4bb-Mediated Antiviral Immunity by Triggering Gut Microbiota Dysbiosis, Metabolic Dysregulation, and Ferroptosis

This study identifies grass carp TLR4bb as a crucial hub coordinating antiviral immunity with heme metabolism, redox balance, and gut microbiota during GCRV-II infection. While TLR4bb recruits TIRAP/MyD88/TRIF to activate IFN signaling against the virus, its synergy with heme and viral sensing tr...

MetabolomicsPomegranate Peel Extract as an Inhibitor of SARS-CoV-2 Spike Binding to Human ACE2 Receptor (in vitro): A Promising Source of Novel Antiviral Drugs
Plant extracts are rich in bioactive compounds, such as polyphenols, sesquiterpenes, and triterpenes, which potentially have antiviral activities. As a consequence of the coronavirus disease 2019 pandemic, caused by the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) virus, thousands of...

MetabolomicsApolipophorin-III modulates antiviral defense in Bombyx mori: an integrated transcriptomic and lipidomic analysis of its inhibitory role against BmNPV infection.

The silkworm (Bombyx mori) is an economically important insect and a lepidopteran model organism. Controlling viral infections is crucial for the sustainable development of sericulture. Bombyx mori nucleopolyhedrovirus (BmNPV) infection can cause large-scale mortality in silkworm populations. Ins...

TranscriptomicsAntiviral RNA interference in mammalian cells
Plants and invertebrates protect themselves from viruses through RNA interference (RNAi), yet it remains unknown whether this defense mechanism exists in mammals. Antiviral RNAi involves the processing of viral long double-stranded (ds) RNA molecules into small interfering RNAs (siRNAs) by the ribon...
