Too Much or Too Little? A Molecular Switch That Decides How Wounds Heal
 Successful wound healing relies on precisely balanced inflammation, yet how inflammatory signals are coordinated over time remains unclear. This study reveals that the NLRP3 inflammasome functions as a dynamic, stage-dependent regulator of acute wound repair. Early after injury, NLRP3 activity promotes immune cell recruitment and initiates tissue repair, whereas prolonged or excessive activation disrupts regeneration and promotes scarring. By synchronizing macrophage behavior, fibroblast migration, and phenotypic transitions, NLRP3 acts as a molecular timer that links inflammation to tissue restoration. These findings explain why both insufficient and excessive inflammation can impair healing and highlight the importance of temporal control in inflammatory signaling.
