Validationsepsis-associated acute lung injuryNrf2LPS-induced SALI mouse modelproposed
This experiment investigated the protective effects of acteoside, a plant-derived phenylethanoid glycoside, against sepsis-associated acute lung injury (SALI) using an LPS-induced mouse model. The study examined whether acteoside could alleviate lung injury by targeting ferroptosis, an iron-dependent cell death process. Researchers evaluated histological changes, pulmonary edema, inflammatory cell infiltration, and various biomarkers of inflammation and ferroptosis. The experiment involved treating mice with LPS to induce SALI, followed by acteoside administration, and then assessing lung tissue damage, inflammatory mediator levels (TNF-α, IL-6, IL-1β, IFN-β), and ferroptosis-related parameters including antioxidant enzyme activities (SOD/GSH), oxidative stress markers (iron, GSSG, 4-HNE, MDA), and expression of key ferroptosis-related proteins (SLC7A11, GPX4, Nrf2, ACSL4, TfR1, PTGS2).
