IL-1β has been reported highly expressed in degenerative intervertebral disc, and our previous study indicated IL-1β facilitates apoptosis of human degenerative nucleus pulposus (NP) cell. However, the underlying molecular mechanism remains unclear. We here demonstrate that IL-1β played a significantly pro-apoptotic effect under serum deprivation. IL-1β decreased Bcl-2/Bax ratio and enhanced cy...

background: nepeta dschuparensis bornm (np) is used as a medicinal herb in iran. in traditional medicine, this herb is extensively employed for curing ailments such as cardiovascular diseases. np has antioxidant and anti-inflammatory properties. this project examined the effects of the np extract on cyclooxygenase-2 (cox-2) and interleukin-1β (il-1β) protein levels and its efficacy in neuroprot...

Microbial sensing plays essential roles in the innate immune response to pathogens. In particular, NLRP3 forms a multiprotein inflammasome complex responsible for the maturation of interleukin (IL)-1β. Our aim was to delineate the role of the NLRP3 inflammasome in macrophages, and the contribution of IL-1β to the host defense against Citrobacter rodentium acute infection in mice. Nlrp3(-/-) and...

The canonical pathway for IL-1β production requires TLR-mediated NF-κB-dependent Il1b gene induction, followed by caspase-containing inflammasome-mediated processing of pro-IL-1β. Here we show that IL-21 unexpectedly induces IL-1β production in conventional dendritic cells (cDCs) via a STAT3-dependent but NF-κB-independent pathway. IL-21 does not induce Il1b expression in CD4(+) T cells, with d...

The potential of hepatocyte growth factor (HGF) to regulate the expression of urokinase plasminogen activator (uPA) in a gastric cancer cell is not widely acknowledged. To identify the genes associated with the plasminogen activator proteolytic axis by HGF, we used cDNA microarray technology and selected genes upregulated or downregulated in two gastric cell lines (NUGC-3 and MKN-28). First, IL...

Background & Aims: Immune system abnormalities such as inflammation, increased autoimmunity and the skewed expression of soluble mediators, including cytokines have been observed in autistic patients. The present study aimed to compare the effects of vitamin D supplementation and/or aquatic exercise training on the serum level of inflammatory cytokines, including IL-1β and IL-1RA, and stereotyp...

In exaggerated pain states, the activated astrocytes release several signalling molecules involved in cellular mechanisms of chronic pain. Among them, nerve growth factor (NGF) and interleukin (IL)-1β are both recognized as potent algogens. We previously showed that histamine is a potent stimulator of NGF production in rat cortical astrocytes in primary culture. Since histamine and IL-1β have c...

Dental calculus is a mineralized deposit associated with periodontitis. The bacterial components contained in dental calculus can be recognized by host immune sensors, such as Toll-like receptors (TLRs), and induce transcription of proinflammatory cytokines, such as IL-1β. Studies have shown that cellular uptake of crystalline particles may trigger NLRP3 inflammasome activation, leading to the ...

Febrile infection-related epilepsy syndrome (FIRES) characteristically affects previously healthy children, who experience a sudden and explosive onset of super-refractory status epilepticus preceded by febrile infection accompanied fulminant neurogenic inflammation. FIRES, however, can affect individuals all ages is subcategory new-onset refractory epilepticus. This definition FIRES excludes i...
