The pro-inflammatory cytokine interleukin-1β (IL-1β) may be involved in several ovulation-associated events, such as proteases synthesis, prostaglandin production and steroidogenesis in granulosa cells. However, the exact effect of IL-1β on progesterone synthesis in granulosa cells and the underlying mechanism remain unclear. By using cultured granulosa-lutein cells collected from women undergoing in vitro fertilization or intracytoplasmic sperm injection, we found that IL-1β up-regulated steroidogenic acute regulatory protein (StAR) expression and progesterone synthesis in granulosa-lutein cells, which was comparable with luteinizing hormone (LH) effect and could be abolished by an IL-1 receptor antagonist...

BACKGROUND: Perturbation of commensal intestinal microbiota has been associated with several autoimmune diseases. Mice deficient in interleukin-1 receptor antagonist (Il1rn (-/-) mice) spontaneously develop autoimmune arthritis and are susceptible to other autoimmune diseases such as psoriasis, diabetes, and encephalomyelitis; however, the mechanisms of increased susceptibility to these autoimmune phenotypes are poorly understood. We investigated the role of interleukin-1 receptor antagonist (IL-1Ra) in regulation of commensal intestinal microbiota, and assessed the involvement of microbiota subsets and innate and adaptive mucosal immune responses that underlie the development of spontaneous arthritis in Il1rn (-/-) mice...

Ischemia-reperfusion (IR)-induced acute lung injury (ALI) is implicated in several clinical conditions including lung transplantation, cardiopulmonary bypass surgery, re-expansion of collapsed lung from pneumothorax or pleural effusion and etc. IR-induced ALI remains a challenge in the current treatment. Carbonic anhydrase has important physiological function and influences on transport of CO2. Some investigators suggest that CO2 influences lung injury. Therefore, carbonic anhydrase should have the role in ALI...

Production and activity of interleukin (IL)-1β are kept under strict control in our body, because of its powerful inflammation-promoting capacity. Control of IL-1β production and activity allows IL-1 to exert its defensive activities without causing extensive tissue damage. Monocytes are the major producers of IL-1β during inflammation, but they are also able to produce significant amounts of IL-1 inhibitors such as IL-1Ra and the soluble form of the decoy receptor IL-1R2, in an auto-regulatory feedback loop...

Periodontal disease is caused by inflammation induced by Porphyromonas gingivalis (P.g.) lipopolysaccharide (LPS) and involves expression of proinflammatory cytokines such as interleukin (IL)-1, IL-6, tumor necrosis factor-α, and receptor activator of nuclear factor kappa B ligand (RANKL), which are implicated in bone resorption. Low-intensity pulsed ultrasound (LIPUS) is commonly used in the treatment of bone fracture. However, the mechanisms by which LIPUS inhibits LPS-induced inflammatory cytokines are poorly understood...

Interleukin-33 (IL-33) is an IL-1 cytokine family member that is involved in the development of chronic inflammatory diseases and the initiation of allergic inflammation in response to pathogens. Porphyromonas gingivalis is a primary pathogen that is involved in chronic periodontitis and its bacterial components induce inflammatory responses. Dendritic cells (DCs) recognize pathogen- associated molecular patterns by expression of pattern-recognition receptors, such as Toll-like receptors (TLRs). DCs play an essential role in resistance to infection and maintenance of mucosal immune system...

Interleukin-1β (IL-1β) is a key molecule in the inflammatory responses elicited during infection and injury. It exerts local effects on synaptic plasticity by binding to IL-1 receptors that are expressed at high levels in the hippocampus. We examined the effects of IL-1β on synaptic plasticity in different hippocampal regions in acute mouse brain slices by measuring long-term potentiation (LTP). IL-1β (1 ng/mL) was applied for 30 min before LTP was induced with high-frequency stimulation (HFS). LTP was significantly impaired by either IL-1β application to the Schaffer collateral-CA1 synapses or the associational/commissural (A/C) fiber-CA3 synapses, which are both dependent on N-methyl-D-aspartate (NMDA) receptor activation...

TGF-β1 is involved in many pathological conditions, including autoimmune disorders, cancer, and cardiovascular and allergic diseases. We have previously found that TGF-β1 can suppress IgE-mediated mast cell activation of human and mouse mast cells. IL-33 is a member of the IL-1 family capable of inducing mast cell responses and enhancing IgE-mediated activation. In this study, we investigated the effects of TGF-β on IL-33-mediated mast cell activation. Bone marrow-derived mast cells cultured in TGF-β1, β2, or β3 showed reduced IL-33-mediated production of TNF, IL-6, IL-13, and MCP-1 in a concentration-dependent manner...

Although interleukin (IL)-33, a member of the IL-1 cytokine family, plays pro-inflammatory roles in immune cells as an "alarmin", little is known regarding the biological actions of IL-33 on vascular endothelial cells. To investigate the effects of IL-33 on vascular endothelial cells, we first screened the IL-33-regulated proteins in human umbilical vein endothelial cells (HUVECs) using a dot blot array, and observed that IL-33 markedly increased growth-regulated oncogene (GRO)-α, a chemokine that is also known as CXCL1...

Pericarditis is a debilitating condition that results from profound inflammation of the pericardial tissue. Between 10-15% of first episodes of acute pericarditis will be followed by several episodes refractory to conventional treatment. Current standard of care for pericarditis treatment includes high-dose non-steroidal anti-inflammatory drugs, colchicine and systemic corticosteroids, each associated with potentially severe toxicities and nominal efficacy. Interleukin-1 (IL-1), an apical pro-inflammatory cytokine, plays an important role as an autocrine magnifier of systemic inflammation in pericarditis...

OBJECTIVE: Temporomandibular disorders (TMD) are a group of conditions affecting the temporomandibular joint (TMJ), leading to jaw dysfunction, joint and muscle pain, and a decrease in quality of life. A communication network of pro- and anti-inflammatory mediators called cytokines maintains the homeostasis of the TMJ. This review will focus on the Interleukin (IL) family of cytokines, which have been quantified in TMJ synovial fluids in a variety of studies. IL-1α and IL-1β have pro-inflammatory effects, while the endogenous receptor antagonist (IL-1RA) inhibits the pro-inflammatory effects of IL-1...

Interleukin-36α (IL-36α), also formerly known as IL-1F6, is pertaining to IL-1 family members that has been shown to play an important pro-inflammatory role in chronic immune disorders. However, the role IL-36α in the setting of cancer remains unknown. Here, in our study, to investigate the clinical relevance of IL-36α in ovarian cancer, clinicopathological significance as well as expression level of IL-36α were analyzed in epithelial ovarian cancer clinical tissues and paired normal control. To explore the biological role of IL-36α in vitro in epithelial ovarian cancer cells, both overexpression and knockdown of IL-36α were performed...

In patients undergoing solid organ transplantation, the presence of an interleukin-1 (IL-1) driven disease may require the addition of IL-1 inhibiting drugs to the standard immunosuppressive regimen to protect against inflammation and negative graft outcome. Three patients undergoing renal transplantation were treated perioperatively with the interleukin-1 receptor antagonist anakinra. Kidney function increased rapidly in all three and the only complications seen were minor infections. In vitro studies report associations between serum and urinary levels of IL-1β and IL-1 receptor antagonist and negative graft outcome, and studies in animals and two small human trials illustrate a possible protective effect of anti-IL-1 therapy after solid organ transplantation...
