IRG1–Itaconic Acid Control of TBK1 Signaling
2026-09-16
A 2025 Cell Reports study identifies the IRG1–itaconic acid axis as a metabolic feedback mechanism that restrains TBK1-driven type I interferon production by modifying TBK1 at Cys605. The work also introduces itaconic acid-derived compounds ITA-5 and ITA-9 as candidate inhibitors for limiting IFN-I-associated hyperinflammation.
