Respiratory diseases pose a grave threat to human life. Therefore, understanding their pathogenesis and therapeutic strategy is important. Ferroptosis novel type of iron-dependent programmed cell death, distinct from apoptosis, necroptosis, autophagy, characterised by iron, reactive oxygen species, lipid peroxide accumulation, as well glutathione (GSH) depletion GSH peroxidase 4 (GPX4) inactivation. A close association between ferroptosis the onset progression respiratory diseases, including chronic obstructive pulmonary disease, acute lung injury, bronchial asthma, fibrosis, cancer, has been reported.

Purpose: Acute lung injury (ALI) is a severe pulmonary disease characterized by damage to the alveoli and blood vessels, leading impairment of function. Studies on effect capsaicin (8-methyl-N-geranyl-6-nonamide, CAP) lipopolysaccharide (LPS)-induced ALI in bronchial epithelial cells transformed with Ad12-SV40 2B (BEAS-2B) are still limited. This study aimed investigate specific mechanism which CAP improves LPS-induced ALI. Methods: The present investigated potential underlying mechanisms vitro vivo via RNA sequencing, Western blotting (WB), quantitative real-time reverse transcription PCR (qRT‒PCR), enzyme-linked immunosorbent assay (ELISA), transmission electron microscopy (TEM). TRPV1 inhibitor AMG9810 AKT agonist SC79 were used confirm protective TRPV1/AKT axis against autophagy rapamycin (Rapa) inhibitors 3-methyladenine (3-MA) bafilomycin A1 (Baf-A1) clarify characteristics autophagy. Results: Our findings demonstrated that effectively suppressed inflammation ALI, both vitro. involves regulation signaling pathway.
