Interleukin-1β (IL-1β) is involved in mood alterations associated with inflammatory illnesses and with stress. The synaptic basis of IL-1β-induced emotional disturbances is still unknown. To address the possible involvement of the endocannabinoid system in IL-1β-induced anxiety, we performed behavioral and neurophysiological studies in mice exposed to stress or to intracerebroventricular inject...

OBJECTIVES Hematoma quality (especially the fibrin matrix) plays an important role in the bone healing process. Here, we investigated the effect of interleukin-1 beta (IL-1β) on fibrin clot formation from platelet-poor plasma (PPP). METHODS Five-milliliter of rat whole-blood samples were collected from the hepatic portal vein. All blood samples were firstly standardized via a thrombelastograp...

OBJECTIVES To investigate the effect of interleukin (IL)-1β on matrix metalloproteinase (MMP)-9 expression in cochlea and regulation of IL-1β-mediated MMP-9 expression by dexamethasone and the molecular and signaling mechanisms involved. METHODS House ear institute-organ of Corti 1 (HEI-OC1) cells were used and exposed to IL-1β with/without dexamethasone. Glucocorticoid receptor antagonist, R...

BACKGROUND The time course of cytokine dynamics after seizure remains controversial. Here we evaluated the changes in the levels and sites of interleukin (IL)-1β expression over time in the hippocampus after seizure. METHODS Status epilepticus (SE) was induced in adult Wistar rats by means of intraperitoneal injection of kainic acid (KA). Subsequently, the time courses of cellular localizatio...

GM-CSF is mostly known for its capacity to promote bone marrow progenitor differentiation, to mobilize and mature myeloid cells as well as to enhance host immune responses. However the molecular actions of GM-CSF are still poorly characterized. Here we describe a new surprising facet of this "old" growth factor as a key regulator involved in IL-1β secretion. We found that IL-1β release, a pivot...

Osteoarthritis (OA) is a degenerative joint disease associated with inflammation. Polygonatum sibiricum polysaccharide (PSP) major group of active components isolated from broad activities including anti-inflammatory effect. However, the role PSP in OA unclear. In present study, we aimed to investigate effects on IL-1β-induced inflammatory response primary human chondrocytes. The results showed...

zataria multiflora (zm) is a thyme-like aromatic plant in the lamiaceae family that grows in central and southern iran. zm is extensively used as a flavor ingredient in a wide variety of foods and is used as part of popular traditional folk remedies. in the present study, zm essential oil (zmo) was obtained from zm leaves via hydro-distillation and then analyzed by gc-ms (gas chromatography-mas...

Background: Interleukin-1 receptor antagonist (IL-1Ra) also known as Anakinra is a of IL-1 especially IL-1β. IL-1β increased in infected COVID-19 patient groups. This study aimed that the IL-1Ra contained Conditioned Medium Wharton’s Jelly Mesenchymal Stem Cells (CM-WJMSCs) has potential to inhibit which one cytokine storms occur COVID patients through an in-silico approach. Objective: aims det...

INTRODUCTION Interleukin-1β (IL-1β) is a major inflammatory cytokine, produced predominantly by innate immune cells through NLRP3-inflammasome activation. Both intrinsic and extrinsic danger signals may activate NLRP3. Genetic variations in NLRP3-inflammasome components have been reported to influence rheumatoid arthritis (RA) susceptibility and severity. We sought to assess the activity of NLR...
