The reverse transsulfuration pathway is the major route for the metabolism of sulfur-containing amino acids. The role of this metabolic pathway in macrophage response and function is unknown. We show that the enzyme cystathionine γ-lyase (CTH) is induced in macrophages infected with pathogenic ba...
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...
Gut microbiome dysbiosis is often associated with immune-mediated diseases. Here, we used germ-free (GF) mice, the synthetic minimal consortium OMM12, and specific pathogen-free (SPF) mice to dissect the causal influence of the microbiome on anti-viral immunity. The lack of microbial diversity af...
In recent years, with the deepening of research on intestinal microbiota, we found intestinal microbiota plays an important role in host immune regulation and barrier maintenance through cross-talk between the microbiota and the host. New evidence suggests that disruption of the fragile balance w...
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...
