Which cell-death programs drive septic acute lung injury?
This review maps how unbalanced autophagy, ferroptosis, and pyroptosis worsen sepsis-induced ALI and which drugs might retune them.

What they did
Authors summarized regulatory networks and experimental evidence (largely LPS/CLP models) for autophagy, ferroptosis, and pyroptosis in sepsis ALI, plus candidate targeted compounds and open challenges.
What they found
They argue death-pathway imbalance is central to septic lung injury, list inflammatory mediators/pathways (TNF-α/IL-1β/IL-6; NF-κB, JAK2/STAT3, MAPK, PI3K/Akt/mTOR, Notch), and catalog interventions that can improve LPS/CLP lung injury in cited studies.
The limits
What it doesn't show
Not a new clinical trial; drug effects are mostly preclinical and not ready as bedside protocols from this paper alone.
Key terms
- Sepsis-induced ALI
- Acute lung injury from dysregulated host response to infection; may progress to ARDS.
- Autophagy
- Lysosomal degradation of cellular components; protective or harmful depending on flux/context.
- Ferroptosis
- Iron-dependent lipid-peroxidation cell death implicated in septic organ injury.
- Pyroptosis
- Inflammatory programmed cell death often tied to inflammasome/caspase pathways.
- CLP / LPS models
- Cecal ligation–puncture and lipopolysaccharide models used to mimic septic ALI.

What type of article is this?
Common questions
Is this a new mouse study?
No—it reviews and tables mechanisms and compounds from the literature.
Why three death modes together?
Authors argue they are interconnected and that imbalance among them triggers septic ALI.
What bedside definition snippet is used?
Among features, ALI hypoxemia with PaO2/FiO2 <300.
Can drugs help?
Cited preclinical work suggests regulating these pathways can lessen LPS/CLP lung injury; clinical translation is still provisional.
