AAV‐Driven miR‐146a Promotes Neurite Outgrowth and Axonal Regeneration in Cortical Neurons

Journal of Neurochemistry, Volume 170, Issue 2, February 2026.
In the adult central nervous system (CNS), neuronal regeneration after injury is limited, resulting in poor functional recovery. MicroRNAs (miRNAs), a class of small noncoding RNAs that control gene expression, have gained attention as potential therapeutic agents, although their contribution to CNS repair remains insufficiently understood.

Antibiotic‐Induced Dysbiosis of the Gut Microbiota Shifts Host Tryptophan Metabolism and Increases the Susceptibility of Mice to Pulmonary Infection With Pseudomonas aeruginosa

Immunology, Volume 175, Issue 4, Page 453-466, August 2025.
Antibiotic‐induced dysbiosis of the gut microbiota shifts host tryptophan metabolism and impairs the innate immune response during Pseudomonas aeruginosa pulmonary infection. (A) Eubiosis: During eubiosis, the intestinal microbiota metabolises tryptophan into indole metabolites, which keeps tryptophan levels within normal serum concentrations. However,
