NLRP3 and fibrosis: Recent investigations demonstrate that miR-223-3p modulates the NLRP3 signaling pathway to alleviate myocardial inflammation and pyroptosis, while miR-34a-5p influences cardiotoxicity through the Sirt1/p66shc axis, and miR-214-3p participates in cardiac fibrosis regulation via LncRNA-MIAT interactions.
