Figure 5 The role of neutrophil extracellular traps in the pathogenesis of ankylosing spondylitis. The interleukin-17 (IL-17)/neutrophil extracellular traps axis directs mesenchymal stem cell osteogenesis, while IL-1β (from both serum and neutrophil extracellular traps) further stimulates neutrophilic IL-17 secretion. This reciprocal interaction establishes a pro-osteogenic inflammatory microenvironment that perpetuates both NETosis and aberrant bone formation. Created by Figdraw, ID: WRRPRa9680. NETs: Neutrophil extracellular traps; IL: Interleukin; MSCs: Mesenchymal stem cells; AS: Ankylosing spondylitis.
