Summary: In recent years, it has been found that high-decibel noise is a risk factor for ischemic heart disease. This study explored the association between noise exposure and postinfarction cardiac remodeling, focusing on the activation of the NLRP3 inflammasome. The results showed a higher activation of the NLRP3 inflammasome in the noisy environment group, highlighting the importance of effective noise prevention in improving postinfarction prognosis.

Summary: This study aimed to investigate the potential role of neutrophils and inflammatory signatures in the pathogenesis of PAMI syndrome. The results showed that PAMI neutrophils displayed increased production of IL-1β and IL-18, along with increased pyrin inflammasome activation and upregulated NF-κB and IFN signaling pathways. These findings suggest the important roles of neutrophils in the pathogenicity of PAMI syndrome.

Summary: The study showed that nicotinamide riboside (NR) treatment alleviated TAC-induced pathological cardiac hypertrophy and dysfunction, partially through regulating the NAD(+)-Sirtuin3-MnSOD signaling pathway to inhibit NLRP3 inflammasome activation and myocardial inflammatory response.

Summary: Metastasis is a major cause of cancer death, often accompanied by therapy resistance. In this study, we discovered that chemotherapy induces neutrophil recruitment and NET formation, leading to reduced therapy response in breast cancer lung metastasis mouse models. We further elucidate that chemotherapy-treated cancer cells secrete IL-1(3, which triggers NET formation. NET-associated proteins, integrin-αv(β3 and matrix metalloproteinase 9, play crucial roles in activating latent TGF-β3 and promoting chemoresistance. Our findings suggest that targeting the IL-1(3-NET-TGF-β3 axis could potentially reduce or prevent chemoresistance in the metastatic setting.

Summary: This study investigates the novel role of bone morphogenetic protein-7 (BMP-7) in ameliorating metabolic alterations, inflammation, pyroptosis, TGF-beta/SMAD cell signaling mechanisms, and the progression of diabetic myopathy. The results suggest that BMP-7 could be a potential treatment option for diabetic muscle myopathy by attenuating hypercholesterolemia-induced inflammation-mediated sarcopenia and adverse muscle remodeling.

Summary: Cardiac hypertrophy is the main adaptive response of the heart to chronic loads, but excessive hypertrophy can promote myocardial fibrosis, dysfunction, and death. Inflammation mediated by NLRP3 inflammasome may aggravate ventricular remodeling and myocardial damage, which is an important mechanism for the progression of heart failure.

Summary: The study revealed the crucial role of Camk2n1 in alleviating ventricular remodeling and malignant ventricular arrhythmia post-MI by inhibiting the phosphorylation of CaMKII8 and reducing inflammation activation in cardiomyocytes. Knockout of Camk2n1 led to excessive activation of NLRP3 inflammasome, exacerbating adverse cardiac remodeling and arrhythmias. Targeting Camk2n1 may serve as a novel therapeutic strategy for post-MI complications.

Summary: The modulation of inflammatory responses is important in the development of cardiac failure. In this study, apoptotic bodies-mimetic nanovesicles derived from apoptotic fibroblasts were developed as a therapeutic strategy for ischemia-reperfusion (IR)-injured hearts. These nanovesicles actively targeted the ischemic myocardium and polarized macrophages to alleviate inflammation. Injection of the nanovesicles attenuated cardiac remodeling and prevented cardiac function exacerbation in IR-injured hearts.

Summary: Platelet-derived miRNAs play a critical role in myocardial inflammation and structural remodeling in response to myocardial ischemia/reperfusion (I/R). In a mouse model with a Dicer gene deletion, disrupted miRNA processing machinery in platelets led to increased myocardial inflammation, impaired angiogenesis, accelerated cardiac fibrosis, and larger infarct size. These findings highlight the importance of platelet-derived miRNA in regulating cellular processes following myocardial I/R.

Summary: mTOR, a mechanistic target of rapamycin, is an evolutionarily conserved pathway that plays a fundamental role in nutrient sensing, growth, metabolism, lifespan, and aging. Recent studies have highlighted the regulatory role of mTOR in innate immune responses and its involvement in the pathogenesis of cardiovascular diseases, especially in acute inflammation and atherosclerotic cardiovascular disease. This review also discusses mTOR's role in trained immunity, immune senescence, and clonal hematopoiesis, as well as its architecture and regulatory complexes.
