Microbial biotherapeutic metabolite alleviates liver injury by restoring hepatic lipid metabolism through PPARα across the gut-liver axis.

Infectious and non-infectious liver diseases are marked by disrupted liver metabolism and are frequently accompanied by gut epithelial barrier dysfunction and microbial dysbiosis, reflecting the compromised gut-liver axis. Despite the pivotal role of the gut-liver axis in health, transformative therapeutic interventions that simultaneously target both the liver and gut remain underexplored. Peroxisome proliferator-activated receptor alpha (PPARα) suppression drives both gut and liver metabolic diseases.

Polluted wetlands contain multidrug-resistance plasmids encoding CTX-M-type extended-spectrum β-lactamases.

While most detailed analyses of antibiotic resistance plasmids focus on those found in clinical isolates, less is known about the vast environmental reservoir of mobile genetic elements and the resistance and virulence factors they encode. We selectively isolated three strains of cefotaxime-resistant Escherichia coli from a wastewater-impacted coastal wetland. The cefotaxime-resistant phenotype was transmissible to a lab strain of E.

Gut germinal center regeneration and enhanced antiviral immunity by mesenchymal stem/stromal cells in SIV infection.

Although antiretroviral therapy suppresses HIV replication, it does not eliminate viral reservoirs or restore damaged lymphoid tissue, posing obstacles to HIV eradication. Using the SIV model of AIDS, we investigated the effect of mesenchymal stem/stromal cell (MSC) infusions on gut mucosal recovery, antiviral immunity, and viral suppression and determined associated molecular/metabolic signatures. MSC administration to SIV-infected macaques resulted in viral reduction and heightened virus-specific responses.
