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...

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...

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...

Adjuvant is an important component of vaccines However, given the limitation of existing adjuvants in variety and mechanism, developing a unique and effective adjuvant is urgently needed for clinal applications. Recent studies have implicated that the mevalonate pathway plays an essential role in va...

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 ...

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...

Analysis of the transcriptional response of HEK293 or HEK293-STAT6 stable cell lines to poly(I:C) transfection. The hypothesis tested was that poly(I:C) transfection is capable of inducing the expression of STAT6-dependent antiviral genes. mRNA isolated from HEK293 or HEK293-STAT6 stable cell lines ...

Higher plants encode four or five DICER-LIKE (DCL) enzymes responsible for the production of small non-coding RNAs which function in RNA interference (RNAi). Different RNAi pathways in plants effect transposon silencing, antiviral defense and endogenous gene regulation. DCL2 acts genetically redunda...

We investigated the roles of IRF-3 and IRF-7 in innate antiviral immunity against dengue virus (DENV). Double-deficient Irf-3-/-7-/- mice infected with the DENV2 strain S221 possessed 1,000-150,000 fold higher levels of viral RNA than wild-type and single-deficient mice 24 hours after infection; how...
