Breaking a mitochondrial danger-STING feed-forward amplifier preserves alveolar-capillary architecture and dampens interferon-chemokine signaling in acute lung injury.
Editor's note
This preclinical mouse study directly administered elamipretide (SS-31) and reported associations with improved oxidative-stress markers and reduced mitochondrial DNA leak in acute lung injury. SS-31 is a genuine intervention arm here, though the strongest effects came from its combination with a separate STING inhibitor, making its isolated contribution partial. As early animal work, the evidence is preliminary but the peptide is a real subject of the study.
Plain-language abstract
In a mouse model of acute lung injury, the peptide elamipretide (SS-31) was administered alone and with a STING inhibitor. SS-31 was associated with improved redox status and reduced mitochondrial leakage, and the combination showed the broadest protective effect on lung structure.
