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...

MetabolomicsAntiviral metabolite 3'-Deoxy-3',4'-didehydro-cytidine is detectable in serum and identifies acute viral infections including COVID-19

BACKGROUND: There is a critical need for rapid viral infection diagnostics to enable prompt case identification in pandemic settings and support targeted antimicrobial prescribing.

METHODS: Using untargeted high-resolution liquid chromatography coupled with...

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...

TranscriptomicsAn essential role for the antiviral endoribonuclease, RNase-L, in antibacterial immunity.
Type I interferons were discovered as the primary antiviral cytokines and are now known to serve critical functions in host defense against bacterial pathogens. Accordingly, established mediators of interferon antiviral activity may mediate previously unrecognized antibacterial functions. RNase-L is...

TranscriptomicsPeroxisomes are signaling patforms for antiviral innate immunity
Analysis of the transcriptional response of mouse embryonic fibroblasts to reovirus infection. The hypothesis tested was that both peroxisomal and mitochondrial MAVS is capable of inducing the expression of antiviral genes. mRNA isolated from MAVS-expressing cells after infection for various times ...

TranscriptomicsA Dicistrovirus-specific inducible antiviral response in Drosophila
The fruit fly Drosophila melanogaster is a good model to unravel the molecular mechanisms of innate immunity, and has led to some important discoveries on the sensing and signalling of microbial infections. The response of drosophila to virus infections remains poorly characterized, and appears to i...

TranscriptomicsRole for ISGF3II in the Antiviral Activity of IFN-gamma
Type-I (e.g. IFN-alpha, IFN-beta) and type-II IFNs (IFN-gamma) have antiviral, antiproliferative, and immunomodulatory properties. Both types of IFN signal through the Jak/STAT pathway to elicit antiviral activity, yet IFN-gamma is thought to do so only through STAT1 homodimers while type-I IFNs act...

TranscriptomicsTranscription profiling of dendritic cells infected with Newcastle Disease Virus reveals that antiviral response is dictated by a choreographed cascade of transcription factors
The dendritic cell (DC) is a master regulator of immune responses. Pathogenic viruses subvert normal immune function in DCs through the expression of immune antagonists. Understanding how these antagonists interact with the host immune system requires knowledge of the underlying genetic regulatory n...
