Key Takeaway
Note the dual pro-inflammatory and immunosuppressive roles of the NLRP3 inflammasome in sepsis pathogenesis.
This systematic review explores the molecular regulatory mechanisms of NLRP3 inflammasome activation and modulation within the context of sepsis. The scope of the review focuses on the dual role of this inflammasome in driving the pathogenesis of sepsis-induced immune dysregulation, specifically looking at pro-inflammatory and immunosuppressive effects.
The authors synthesize evidence indicating that the NLRP3 inflammasome serves as a central molecular platform in sepsis. It contributes to both hyperactivation and immunoparalysis through distinct pro-inflammatory and immunosuppressive pathways. This dual functionality is a key feature of the immune dysregulation observed during the progression of the disease.
While the review highlights the potential of NLRP3-targeted strategies as therapeutic targets to restore immune homeostasis, the specific clinical outcomes and safety profiles of such interventions were not reported. The findings emphasize the complexity of the NLRP3 inflammasome in the pathogenesis of sepsis-induced immune dysfunction.
Clinicians should recognize the NLRP3 inflammasome as a critical component in the inflammatory and immunosuppressive phases of sepsis. Further research is required to determine how modulating this platform might impact patient outcomes.

Sepsis remains a major challenge in critical care medicine worldwide, characterized by a dynamic imbalance of the immune system between two extremes: “immunoparalysis” and “hyperactivation.” This dysregulation severely affects patient survival. The NLRP3 inflammasome, a central molecular platform in innate immunity, has recently been shown to play a critical dual role in the pathogenesis of sepsis. This review systematically outlines the structural features and activation mechanisms of the NLRP3 inflammasome, elaborates on its pro-inflammatory and immunosuppressive effects in sepsis-induced immune dysregulation, and summarizes the associated signaling pathways and regulatory networks. By integrating recent advances in basic and clinical research, we provide an in-depth analysis of the molecular regulatory mechanisms of the NLRP3 inflammasome in sepsis and evaluate its potential as a therapeutic target. Furthermore, this review discusses the opportunities and challenges in translating NLRP3-targeted strategies into clinical practice, emphasizing the potential of precise NLRP3 modulation to restore immune homeostasis in sepsis. Our findings may provide a theoretical foundation and future research directions for developing novel therapeutic approaches.
