This study identifies SIRT5 as a key regulator of arginine metabolism and T cell function through its interaction with ASL, showing that SIRT5 depletion reduces anti-inflammatory effects of NAD+ precursors.

This paper identifies a biphasic regulatory loop where type 1 interferon initially enhances mitochondrial fatty acid oxidation (FAO) to amplify its own production, but excessive IFN signaling induces ISG15-mediated inhibition of FAO, creating a negative feedback loop to control inflammation.
