Abstract:
This study examines the immune-modulatory effects of cefiderocol in a murine model of lipopolysaccharide (LPS)-induced acute lung injury (ALI). Cefiderocol pretreatment significantly reduced lung tissue damage, lowered pro-inflammatory cytokines, and decreased ferroptosis markers. Its protective effect was comparable to that of the ferroptosis inhibitor ferrostatin-1, while cefepime showed limited efficacy. These findings suggest that cefiderocol has an immuno-mediated role in LPS-induced ALI, potentially by modulating ferroptosis and inflammation, warranting further investigation for sepsis-related complications.
