Pyroptosis is a novel type of programmed cell death, which is closely related with the pathogenesis of myelodysplastic syndromes (MDS). The recent studies showed that all of S100A9/TLR4, S100A9/CD33 and Nox/ROS signaling pathways can activate oxygen-sensitivity NLRP3 inflammasome and then induce the pyroptosis of hematopoeitic stem cells (HSC) / hematopeitic pregenitor cells (HPC), resulting in ineffective hematopoiesis in patients with MDS. Further studies on the role and molecular mechanism of pyroptosis in the pathogenesis of MDS will provide the potential opportunity for the diagnosis and treatment of MDS. Here, the recent advances in the role and mechnism of pyroptosis in the pathogenesis of MDS are reviewed.

Hepatocellular carcinoma (HCC) represents the most prevalent form of primary liver cancer and has a high mortality rate. Caspase-8 plays a pivotal role in an array of cellular signaling pathways and is essential for the governance of programmed cell death mechanisms, inflammatory responses, and the dynamics of the tumor microenvironment. Dysregulation of caspase-8 is intricately linked to the complex biological underpinnings of HCC.

Idiopathic inflammatory myopathies (IIM) are a group of systemic autoimmune diseases characterized by muscle weakness and elevated serum creatine kinase levels. Recent research has highlighted the role of the innate immune system, particularly inflammasomes, in the pathogenesis of IIM. This review focuses on the role of inflammasomes, specifically NLRP3 and AIM2, and their associated proteins in the development of IIM.

To investigate the role and mechanism of triptophenolide (TRI) in resisting rheumatoid arthritis (RA). Network pharmacology analysis results suggested that TRI was related to multiple inflammation-related signaling proteins, and possessed the stable structural configuration. In animal experiments, TRI suppressed RA in mice, inhibited tissue inflammation, and improved synovial injury.

Autophagy is a physiologically regulated cellular process orchestrated by autophagy-related genes (ATGs) that, depending on the tumor type and stage, can either promote or suppress tumor growth and progression. It can also modulate cancer stem cell maintenance and immune responses. Therefore, targeted manipulation of autophagy may inhibit tumor development by overcoming tumor-promoting mechanisms.

Acute liver failure (ALF) is a life-threatening clinical syndrome characterized by high-grade inflammation and multi-organ failure. Our previous study shows that targeting the M2 isoform of pyruvate kinase (PKM2) to inhibit macrophage inflammation may be a promising strategy for ALF treatment. however, the mechanism by which PKM2 regulates the inflammatory response is unclear.
