Article Abstract
The NLRP3 inflammasome plays a pivotal role in regulating inflammation and immune responses. Its activation can lead to an inflammatory response and pyroptotic cell death. This is beneficial in the case of infections, but excessive activation can lead to chronic inflammation and tissue damage. Moreover, while most of the mammalian genome is transcribed as RNAs, only a small fraction codes for proteins. Among non-protein-coding RNAs, long non-coding RNAs (lncRNAs) have been shown to play key roles in regulating gene expression and cellular processes. They interact with DNA, RNAs, and proteins, and their dysregulation can provide insights into disease mechanisms, including NLRP3 inflammasome activation. Here, we systematically analyzed previously published RNA sequencing (RNA-seq) data of NLRP3 inflammasome activation in monocytes/macrophages to uncover inflammasome-regulated lncRNA genes. To uncover the functional importance of inflammasome-regulated lncRNA genes, one inflammasome-regulated lncRNA, , was knocked down in an in vitro model of macrophage polarization. The results indicate that silencing of resulted in the up-regulation tumor necrosis factor (), suggesting that this lncRNA might be involved in pro-inflammatory response in macrophages. To make our analyzed data more accessible, we developed the web database InflammasomeDB.

Inflammatory adhesion mediates myocardial segmental necroptosis induced by mixed lineage kinase domain-like protein in acute myocardial infarction.

Purpose: Cardiomyocyte death is a major cytopathologic response in acute myocardial infarction (AMI) and involves complex inflammatory interactions. Although existing reports indicating that mixed lineage kinase domain-like protein (MLKL) is involved in macrophage necroptosis and inflammasome activation, the downstream mechanism of MLKL in necroptosis remain poorly characterized in AMI.
Methods: MLKL knockout mice (MLKL), RIPK3 knockout mice (RIPK3), and macrophage-specific MLKL conditional knockout mice (MLKL) were established.

Purpose: BMS-986299 is a first-in-class, NOD-, LRR-, and pyrin-domain containing-3 (NLRP3) inflammasome agonist enhancing adaptive immune and T-cell memory responses.
Materials And Methods: This was a phase-I (NCT03444753) study that assessed the safety and tolerability of intra-tumoral BMS-986299 monotherapy (part 1A) and in combination (part 1B) with nivolumab, and ipilimumab in advanced solid tumors. Reported here are single-center results.

Most of the pyroptosis inhibitors targeted Gasdermin D (GSDMD) are functioning by restraining GSDMD-N (p30) oligomerization. For the first time, this work discovered a pyroptosis inhibitor taking effect by degrading p30 and GSDMD. As the principal bioactive constituent in Erigeron breviscapus, scutellarin (SCU) assumes a pivotal role in the realm of anti-inflammatory processes.

Silibinin, a major compound of silymarin, has been reported to alleviate respiratory diseases including acute lung injury, asthma, chronic obstructive pulmonary disease, and pulmonary fibrosis through its antifibrotic, anti-inflammatory, and antioxidant properties. However, the specific mechanisms underlying its therapeutic effects, particularly in allergic asthma, are not fully understood. With the increasing prevalence and impact of allergic asthma, there is a need to elucidate the exact underlying mechanisms of its potential treatment effects.
