IL-1 transcriptional responses to LPS are regulated by a complex …
IL-1β is transcriptionally and post-translationally regulated and is primarily induced after recognition of microbial patterns (5, 6). Monocytes appear to be the main cell that produces IL-1β following stimulation with LPS.
ZBP1 promotes LPS-induced cell death and IL-1β release via RHIM ...
Jan 4, 2021 · To aid in a thorough mechanistic inquiry of CASP8-mediated cell death, we used bone marrow-derived macrophages (BMDMs) activated with lipopolysaccharide (LPS) and the small-molecule inhibitor of...
Downregulation of Inflammatory Cytokine Release from IL-1β and LPS …
In this study, we investigate the effect of MyD88 dimerisation inhibitor ST2825 on cytokine production from rhIL-1β and LPS-stimulated peripheral blood mononuclear cells (PBMC) from healthy blood donors (HBD).
Understanding the mechanism of IL-1β secretion - PMC
Interleukin-1β (IL-1β) is a potent pro-inflammatory cytokine that is crucial for host-defence responses to infection and injury [1]. It is also the best characterised and most studied of the 11 IL-1 family members.
Inflammasome-dependent IL-1β release depends upon membrane …
Feb 12, 2016 · To stimulate the release of IL-1β, cells were primed with bacterial endotoxin (LPS, 1 μg/ml for macrophages or 100 ng/ml for neutrophils, 4 h – signal 1) and then treated with ATP (5 mM, from...
Lipopolysaccharide/adenosine triphosphate induces IL‑1β and IL …
In this study, we used lipopolysaccharide (LPS) and adenosine triphosphate (ATP) to simulate an inflammatory environment as the testing model. We found that the exposure of RAW264.7 cells to LPS/ATP triggered the activation of caspase-1 (P<0.01) and the cleavage of interleukin (IL)-1β (P<0.01), as well as the release of other cytokines, such ...
Lipopolysaccharide-Mediated Induction of Concurrent IL-1β …
Upon lipopolysaccharide (LPS) triggering of toll-like receptor (TLR)-4 and subsequent ATP signaling, the NOD-like receptor containing-pyrin domain 3 (NLRP3) inflammasome is activated to cleave pro-caspase-1 into caspase-1, allowing the secretion of IL-1β.
IL-1 Transcriptional Responses to Lipopolysaccharides Are ... - PubMed
Mar 1, 2020 · IL1A, IL1B, and IL1RN were rapidly induced after stimulation with LPS; however, IL1B mRNA production was less inhibitable by iBET151, suggesting it does not use pause-release regulation.
CXCL12 inhibits inflammasome activation in LPS-stimulated BV2 …
Jul 15, 2021 · LPS induced the expression of the inflammasome components NLRP3, NLRC4 and ASC, the secretion of the cytokines IL-1b and IL-18 and the activation of caspase-1 protease in BV2 cells. Pre-treatment with CXCL12 significantly reduced LPS-induced IL-1b/IL-18 secretion and inflammasome induction.
NLRP3 inflammasome-driven IL-1β and IL-18 contribute to ...
Jul 1, 2023 · Here, we investigated the role of the NLRP3 inflammasome in a murine model of lipopolysaccharide (LPS)-induced SCM. LPS injection induced cardiac dysfunction, damage, and lethality, which was significantly prevented in NLRP3−/− mice, compared to wild-type (WT) mice.
