Article Abstract

Tim-3/Gal-9 and the NLRC4 inflammasome contribute to glioma progression. However, the underlying mechanisms involved are unclear. Here, we observed that Tim-3/Gal-9 expression increased with glioma malignancy and found that Tim-3/Gal-9 regulate NLRC4 inflammasome formation and activation. Tim-3/Gal-9 and NLRC4 inflammasome-related molecule expression levels increased with WHO glioma grade, and this association was correlated with low survival. We investigated NLRC4 inflammasome formation by genetically regulating Tim-3 and its ligand Gal-9. Tim-3/Gal-9 regulation was positively correlated with the NLRC4 inflammasome, NLRC4, and caspase-1 expression. Tim-3/Gal-9 did not trigger IL-1β secretion but were strongly positively correlated with caspase-1 activity as they induced programmed cell death in glioma cells. A protein-protein interaction analysis revealed that the FYN-JAK1-ZNF384 pathways are bridges in NLRC4 inflammasome regulation by Tim-3/Gal-9. The present study showed that Tim-3/Gal-9 are associated with poor prognosis in glioma patients and induce NLRC4 inflammasome formation and activation. We proposed that a Tim-3/Gal-9 blockade could be beneficial in glioma therapy as it would reduce the inflammatory microenvironment by downregulating the NLRC4 inflammasome.

Article Synopsis
  • - The study explores the potential of chlorquinaldol (CQ), an antimicrobial agent, as a specific inhibitor of the NLRP3 inflammasome, which is linked to various inflammatory diseases, highlighting its promise for drug repurposing.
  • - CQ effectively suppresses NLRP3 inflammasome activation in both mouse and human macrophages primarily by blocking the interaction between NLRP3 and ASC, while having minimal impact on other inflammasomes like NLRC4 and AIM2.
  • - In vivo tests showed that CQ significantly improves conditions in mouse models of LPS-induced peritonitis, DSS-induced colitis, and MSU-induced gouty arthritis, suggesting its therapeutic potential for treating NLRP3-related

Abnormal activation of NLRP3 inflammasome causes the progression of gout, and no small-molecule inhibitor of NLRP3 has been approved yet for clinical use. In this study we established a nigericin-induced inflammasome activation cell model for screening of a natural product library by measuring IL-1β secretion in cell supernatants. Among 432 compounds tested, we found that hypocrellin A (HA), one of the major active components of a traditional ethnic medicinal fungus Hypocrella bambusea in the Northwest Yunnan of China, exhibited the highest inhibition on IL-1β production (IC = 0.

Structural insights into the ATP-dependent activation of NOD-like receptor with pyrin 3 (NLRP3) protein by molecular dynamics simulation.

J Biomol Struct Dyn

Department of Biochemistry & Molecular Biology, Cumming School of Medicine, University of Calgary, Calgary, Canada.

The inflammasome-forming NOD-like receptor containing pyrin-3 (NLRP3) protein is a critical player in the innate immune responses to cellular danger signals. New structural data of NLRP3 provide a framework to probe the conformational impact of nucleotide binding. In this study, microsecond molecular dynamics (MD) simulations were used to detail information on the unique structural conformations adopted by NLRP3 with ATP or ADP binding.

Taurine potentiates artemisinin efficacy against malaria by modulating the immune response in Plasmodium berghei-infected mice.

Parasit Vectors

November 2024

Key Laboratory of Livestock Infectious Diseases, Ministry of Education, and Key Laboratory of Ruminant Infectious Disease Prevention and Control (East), Ministry of Agriculture and Rural Affairs, College of Animal Science and Veterinary Medicine, Shenyang Agricultural University, 120 Dongling Road, Shenyang, 110866, China.

Background: Artemisinin (ART) is a frontline drug for the treatment of malaria; however, the emergence of ART-resistant Plasmodium strains necessitates increasing ART sensitivity. Given that taurine (TAU) has been shown to have immunomodulatory activity, we investigated the effects of TAU as an adjunct therapy to ART in mice infected with Plasmodium berghei.

Methods: Mice infected with P.
