Ferritin is the major iron storage molecule of vertebrates, which can be detected in serum under numerous conditions, including inflammatory, neurodegenerative, and malignant diseases. Given this character, serum ferritin is frequently used as a biomarker in clinical settings. How the ferritin secreted to the serum has attracted much attention. Although some studies have found ferritin was mediated via the endoplasmic reticulum (ER)-Golgi secretion pathway or secretory lysosomes trafficking pathway under normal conditions, the secretion pathway of ferritin under pathological conditions, especially in sepsis is not very clear. In this report, we adopt a murine sepsis model to study the secretion pathway of ferritin in sepsis. We demonstrated caspase-11-GSDMD pathway and associated pyroptosis are required for secretion of ferritin in vitro and in vivo in sepsis. Moreover, our work connects pyroptosis to serum ferritin secretion and suggests a passive release process of ferritin, enhancing our understanding of the mechanism of ferritin secretion.
