Concurrently, DEX suppresses the nuclear factor-κB (NF-κB) signaling pathway, inhibits macrophage M1 polarization, and alleviates hepatic inflammation. The oxygen produced by MnO<sub>2</sub> catalysis further mitigates hypoxia, decreases lactic acid accumulation, and downregulates histone lactylation, synergizing with DEX to enhance NF-κB pathway inhibition and amplify anti-inflammatory effects. Transcriptomic analyses revealed that MSC-exo/MnO<sub>2</sub>@DEX significantly enhances antioxidant capacity, metabolic processes, and immune function, while improving liver function and suppressing ferroptosis, lactylation and inflammatory responses.
