it was known that il-1β-induced rapid expression of mir-146a, which regulated the secretion of inflammatory chemokines in human a549 alveolar epithelial cells. however, little is known about the level of primary mir-146a and the downstream biogenesis of mir-146a in a549 cells. we examined the levels of primary mir-146a and mature mir-146a in a549 cells following treatment with pharmacological i...

We investigated the association between 3 main proinflammatory cytokines [interleukin (IL)-1β and IL-6] and the risk of acute pancreatitis. Polymerase chain reaction-restriction fragment length polymorphism was used to genotype IL-1β+3954 C/T (rs1143634) and IL-1β-511 C/T (rs16944) and IL-6 -174 G/C (rs1800795) and IL-6 -634 C/G (rs1800796). The genotype distributions of IL-1β+3954 C/T (rs11436...

Interleukin‑1β (IL‑1β) has a significant role in osteoarthritis (OA). The purinergic receptor, P2X4, has previously been implicated in IL‑1β secretion. The NLRP1 inflammasome mediates the production of IL‑1β in inflammatory disorders. However, it is unknown whether P2X4 modulates NLRP1‑mediated IL‑1β release. In the present study, the correlation between the P2X4 receptor and NLRP1 was investig...

In this study we investigated the implication of NLRP3 inflammasomes in the pathogenesis of idiopathic pulmonary fibrosis (IPF) and rheumatoid arthritis-usual interstitial pneumonia (RA-UIP).NLRP3 inflammasome activation at baseline and following stimulation with lipopolysaccharide/ATP was evaluated by measuring interleukin (IL)-1β and IL-18 levels released in the bronchoalveolar lavage fluid (...

Interleukin-1β (IL-1β) mediates many of the behavioral responses to infection and inflammation, and IL-1β-converting enzyme (ICE) processes intracellular IL-1β, leading to its maturation and secretion. Here we demonstrate that intracerebroventricular injections of lipopolysaccharide (LPS) produced a greater reduction in both food intake and food-motivated behavior in wild-type compared with ICE...

Objective: In cardiovascular diseases, inflammatory response plays an important role and affects heart function. As a flavonoid compound, p-coumaric acid (pCA), commonly exists in many fruits and vegetables and has a therapeutic effect on inflammatory diseases due to its anti-inflammatory properties. The purpose of the present study was to investigate pCA anti-inflammatory effect and the miRNAs...

BACKGROUND Proinflammatory cytokine interleukin-1β (IL-1β) released from spinal microglia plays an important role in the maintenance of acute and chronic pain states. However, the cellular basis of this action remains poorly understood. Using whole-cell patch-clamp recordings, we examined the action of IL-1β on AMPA- and NMDA-receptor-mediated currents recorded from substantia gelatinosa (SG) n...

Purpose. To investigate how multipotent retinal stem cells (RSCs) isolated from mice respond to the proinflammatory signaling molecules, IL-1β, IL-18, and IL-17A. Materials and Methods. RSCs were cultured in a specific culture medium and were treated with these cytokines. Cell viability was detected by MTT assay; ultrastructure was evaluated by transmission electron microscopy; expression of IL...

Duchenne muscular dystrophy (DMD) is a severe X-linked recessive muscle disorder caused by mutations in the dystrophin gene. Nonetheless, secondary processes involving perturbation of muscle regeneration probably exacerbate disease progression, resulting in the fatal loss of muscle in DMD patients. A dysfunction of undifferentiated myogenic cells is the most likely cause for the reduction of re...
