BACKGROUND: Inflammation is closely related to atrial fibrillation (AF) pathogenesis, and interleukin-37 (IL-37) represents a new member of the anti-inflammatory cytokines. HYPOTHESIS: IL-37 might play an important role in AF development and act as a potential risk factor for AF diagnosis. METHODS: The mRNA level of IL-37 in peripheral blood mononuclear cells (PBMCs) and serum IL-37 levels in AF patients and healthy controls were measured by real-time polymerase chain reaction (RT-PCR) and enzyme-linked immunosorbent assay (ELISA)...

Myocardial inflammatory responses to endotoxemia are enhanced in old mice, which results in worse cardiac dysfunction. Anti-inflammatory cytokine interleukin (IL)-37 has a broad effect on innate immunoresponses. We hypothesized that IL-37 suppresses myocardial inflammatory responses to protect cardiac function during endotoxemia in old mice. Old (20-24month) wild-type (WT), and IL-37 transgenic (IL-37tg) mice were treated with lipopolysaccharide (LPS, 0.5mg/kg, iv) or normal saline (0.1ml/mouse, iv). Six hours later, left ventricle (LV) function was assessed using a pressure-volume microcatheter...

BACKGROUND: IL-37 emerges as a natural suppressor of inflammatory responses. The potential role of IL-37 in the pathology of atherosclerosis is unclear. The purpose of this study was to assess IL-37 profile in acute coronary syndrome (ACS) and the prognostic role of this cytokine in patients with ST-segment elevation acute myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PPCI). METHODS: In a case-control study, we prospectively enrolled 216 patients undergoing the first coronary angiography, which consisted of 5 groups: normal (n=57), stable angina (SAP, n=36), unstable angina (UAP, n=42), non-STEMI (n=36), STEMI (n=45)...

IL-37 has been described as a natural inhibitor of immune responses. Monoclonal antibody (mAb) against human IL-37b with high affinity and specificity can serve as a molecular probe to detect IL-37 and study IL-37 functions, mechanisms and related signal pathways in inflammatory diseases. However, there are very few such mAbs against human IL-37 commercially available so far. In the current study, monoclonal antibodies against human IL-37b were developed by fusing splenocytes from immunized mouse with SP2/0 myeloma cells and polyethylene glycol...

Myocarditis is a heterogeneous group of disorders defined by inflammation of the heart muscle with an excessively activated immune response. Numerous interventions have been investigated for the treatment of myocarditis while success is limited. Interleukin-37 (IL-37), a novel member of the IL-1 cytokine family, is a natural inhibitor of innate immunity associated with autoimmune diseases. However, the modulatory effect of IL-37 in myocarditis is unknown. In this study, we investigated the immunological regulation of IL-37 in the coxsackievirus B3-induced model of murine viral myocarditis...

IL-1 family member interleukin 37 (IL-37) has broad antiinflammatory properties and functions as a natural suppressor of innate inflammation. In this study, we demonstrate that treatment with recombinant human IL-37 reverses the decrease in exercise performance observed during systemic inflammation. This effect was associated with a decrease in the levels of plasma and muscle cytokines, comparable in extent to that obtained upon IL-1 receptor blockade. Exogenous administration of IL-37 to healthy mice, not subjected to an inflammatory challenge, also improved exercise performance by 82% compared with vehicle-treated mice (P = 0...

The interleukin 1 family plays an important role in the immune and inflammatory responses. Coronary artery disease (CAD) is a chronic inflammatory disease. However, the genetic association between IL-37, the seventh member of the IL-1 family, and CAD is unknown. Here we show that a single nucleotide polymorphism in the IL-37 gene (rs3811047) confers a significant risk of CAD. We have performed an association analysis between rs3811047 and CAD in two independent populations with 2,501 patients and 3,116 controls from China...

Calcific aortic valve disease is a chronic inflammatory process, and aortic valve interstitial cells (AVICs) from diseased aortic valves express greater levels of osteogenic factors in response to proinflammatory stimulation. Here, we report that lower cellular levels of IL-37 in AVICs of diseased human aortic valves likely account for augmented expression of bone morphogenetic protein-2 (BMP-2) and alkaline phosphatase (ALP) following stimulation of Toll-like receptor (TLR) 2 or 4. Treatment of diseased AVICs with recombinant human IL-37 suppresses the levels of BMP-2 and ALP as well as calcium deposit formation...

Atopic dermatitis (AD) in infancy is believed to have distinct features as compared to AD in other age groups, and little is known about cytokine production in infants with AD. We aimed to measure the serum cytokine levels of infants with atopic dermatitis and evaluate the association of new anti-inflammatory cytokines with the disease. Eighty-one infant patients with AD and 52 healthy controls were involved in this study. The serum levels of major pro- and anti-inflammatory cytokines of the T-helper (Th) subtypes, as well as more recently defined interleukins (IL-27, IL-35, and IL-37), were measured using the ELISA method...

Mast cells (MCs) are mediators of allergy and inflammation and participate in the growth of cancer cells. MCs can promote both neoangiogenesis and tumor growth. They increase in the stroma of certain tumors where they can be recruited by tumor-derived chemoattractants, such as monocyte chemotactic protein-1 (MCP-1), RANTES and stem cell factor (SCF) to selectively secrete inflammatory molecules including chemical mediators and cytokines (TNF, IL-6 and IL-1). However, MC differentiation pathways and heterogeneity in cancer are still poorly understood...

Interleukin-37 (IL-37), a novel member of the IL-1 family, plays fundamental immunosuppressive roles by broadly reducing both innate inflammation and acquired immunity, but whether it is involved in the pathogenesis of tuberculosis (TB) has not been clearly elucidated. In this study, single nucleotide polymorphism (SNP) analysis demonstrated an association of the genetic variant rs3811047 of IL-37 with TB susceptibility. In line with previous report, a significant elevated IL-37 abundance in the sera and increased expression of IL-37 protein in the peripheral blood mononuclear cells (PBMC) were observed in TB patients in comparison to healthy controls...

Multiple interactions between the immune system and sleep are known, including the effects of microbial challenge on sleep or the effects of sleep loss on facets of the immune response. Cytokines regulate, in part, sleep and immune responses. Here we examine the role of an anti-inflammatory cytokine, interleukin-37 (IL-37) on sleep in a mouse strain that expresses human IL-37b (IL37tg mice). Constitutive expression of the IL-37 gene in the brains of these mice under resting conditions is low; however, upon an inflammatory stimulus, expression increases dramatically...

The objectives of this study were to examine the serum levels of interleukin (IL)-37 and its clinical association in patients with primary Sjögren's syndrome (pSS) and to investigate whether or not IL-37 participates in the regulation of the pathogenesis of pSS. ELISA was used to analyse the serum levels of IL-37, total IL-18 and IL-18 binding protein (IL-18BP). The level of free IL-18 was calculated based on the mass action law. The correlations between the IL-37 serum levels with the laboratory values and the total IL-18 and IL-18BP serum levels were analyzed by a Spearman's correlation test...

BACKGROUND AND AIM: Microscopic colitis, comprising collagenous colitis and lymphocytic colitis, is a common cause of chronic diarrhea. Previously, we showed enhanced chemokine productions in microscopic colitis patients, indicating dysregulated immune cell chemotaxis in the immunopathogenesis. We also showed decreased mRNA of IL-37, mainly regarded as an anti-inflammatory cytokine, in the colonic mucosa of these patients, potentially an important factor for the chronicity of the colitis...

In 1986, we reported a multiple biological effect of IL-1 including immunological, inflammatory, and tumor killing activity. Since then other IL-1 family cytokines have been discovered, some with inflammatory and other with anti-inflammatory activity. In this review article, we speculate on the possible inhibitory effect of IL-37 in the light of new findings. IL-37, formerly termed IL-1 family member 7 (IL-1F7), binding IL-18 receptor α chain, acts as a cytokine with intracellular as well as extracellular functionality and as a natural inhibitor of immune responses and inflammation...

Naturally occurring CD4(+)CD25(+) regulatory T cells (Tregs) are essential for the suppression of autoimmunity and can control the immune-mediated pathology during the early phase of sepsis. Our previous data showed that silencing interleukin-37 (IL-37) in human CD4(+)CD25(+) Tregs obviously reduced the suppressive activity of CD4(+)CD25(+) Tregs. Here, we found that rhIL-37 stimulation markedly enhanced the suppressive activity of CD4(+)CD25(+) Tregs isolated from naive C57BL/6 J mice in the absence or presence of lipopolysaccharide (LPS)...
