[Mechanisms of NLRP3 inflammasome-mediated pyroptosis in chronic heart failure and research progress in traditional Chinese medicine].

ABSTRACT

Chronic heart failure(CHF) is a severe cardiovascular disease characterized by a complex pathogenesis involving myocardial structural and functional abnormalities and the activation of inflammatory responses. The NOD-like receptor thermal protein domain-associated protein 3(NLRP3) inflammasome, acting as a sensor for inflammatory cells, plays a pivotal role in the development of CHF. Research indicates that the activation of the NLRP3 inflammasome can induce inflammatory responses, leading to cardiac inflammation and impairing myocardial function, and it is correlated with the severity of CHF. Traditional Chinese medicine(TCM) has garnered increasing attention as a traditional therapeutic approach in recent years. Various TCM drugs and treatment methods have exhibited potential efficacy in suppressing inflammatory responses, alleviating myocardial cell pyroptosis, improving myocardial structure and function, and inhibiting myocardial fibrosis. Several TCM drugs and their extracts have been utilized in CHF treatment, with mechanisms potentially involving the inhibition of NLRP3 inflammasomes and the mitigation of inflammatory responses. The article provided an overview of the composition, structural characteristics, initiation, and activation modes of the NLRP3 inflammasome, its mechanisms in CHF, and the research progress of TCM in CHF treatment. It aims to offer references and foundations for a deeper understanding of CHF pathogenesis and subsequent development of new therapeutic strategies.
