BACKGROUND & AIMS: Patients with acute-on-chronic liver failure (ACLF) usually exhibit defective monocyte function and excessive systemic inflammatory response. Interleukin-33 (IL-33) acts as a danger-associated molecular pattern (DAMP) to modulate immune response. However, the role of IL-33 in regulating monocyte function during hepatitis B-precipitated ACLF (HB-ACLF) in response to lipopolisaccharide (LPS) has not been clear. METHODS: In the present study, the levels of IL-33/ST2 in blood and liver samples collected from patients with HB-ACLF, chronic hepatitis B (CHB) and normal controls and the associated of those findings with disease severity were analyzed...

This was a retrospective observational study. The aim of this study was to evaluate functional outcomes in children treated for Gartland III supracondylar humerus (SCH) fracture with neurovascular (NV) injuries using validated outcome measures. A secondary goal was to determine whether clinical parameters such as age at injury, sex, weight, fracture site, and/or direction of displacement could predict NV injury at the time of fracture or long-term functional outcomes in these patients.One hundred fifty-four patients of Gartland III SCH fractures between March 2004 and May 2013 were studied retrospectively...

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...

hCAP-18/LL-37 is an antimicrobial peptide that is mainly expressed in epithelial cells. Gingival epithelial cells play pivotal roles in antimicrobial defense by expressing hCAP-18/LL-37. Porphyromonas gingivalis is a primary pathogen for chronic periodontitis and produces cysteine proteinase gingipains, which induce proinflammatory cytokines production, leading to enhance inflammatory responses. In contrast, gingipains attenuate immune responses, leading to induce anti-inflammatory responses. In this study, we investigated the ability of gingipains to attenuate P...

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...

BACKGROUND/AIMS: A growing body of evidence supports an important role of inflammatory-cytokines in development and progression of metabolic-syndrome (MetS), which explain, at least in part, its relationship with an increased cardiovascular-risk. Several studies have reported the therapeutic-impact of crocus-sativus in preclinical/clinical setting. Here we have explored the effects of crocus-sativus, saffron, on the modulation of twelve serum cytokines in subjects with MetS in a randomized control trial...

Abnormal osteoclast activation contributes to osteolytic bone diseases (OBDs). It was reported that curdlan, an agonist of dectin-1, inhibits osteoclastogenesis. However, the underlying mechanisms are not fully elucidated. In this study, we found that curdlan potently inhibited RANKL-induced osteoclast differentiation and the resultant bone resorption. Curdlan inhibited the expression of nuclear factor of activated T-cells, cytoplasmic 1 (NFATc1), the key transcriptional factor for osteoclastogenesis. Notably, dectin-1 activation increased the expression of MafB, an inhibitor of NFATc1, and IL-33 in osteoclast precursors...

We investigated the effects of microRNA-587b (miR-487b) in a rat model of chronic heart failure (CHF). Wistar rats were assigned to 10 groups (n=8 per group). Expression of interleukin-33 (IL-33), somatostatin 2 (ST2), IL-6, and TNF-α was higher in the CHF group than the control group. In the CHF, negative control (NC) for si-IL-33, NC for miR-487b mimic, NC for miR-487b inhibitor, and miR-487b inhibitor + si IL-33 groups, as compared to the blank and sham groups: steroid binding protein (SBP), D binding protein (DBP), left ventricular systolic pressure (LVSP), ± dp/dtmax, and superoxide dismutase (SOD) were all lower; myocardial fibrosis, MDA, left ventricular end-diastolic pressure (LVEDP), myocardial apoptosis rate, IL-6, and TNF-α were all higher; levels of IL-33 and ST2 mRNA and protein were higher; and levels of miR-487b were lower...

IL-18 polymorphisms influence the transcriptional activity of the IL-18 gene and associated with various diseases. However, their relationships with hepatitis B virus-related liver diseases had not reached a consensus. So we conducted this case-control study with a view to clarifying the association. We included four groups: healthy controls, chronic hepatitis B virus (CHB) carriers, liver cirrhosis (LC) and hepatocellular carcinoma (HCC) groups with each group of 250 persons. Odd ratios (ORs) and 95% confidence intervals (95%CIs) with or without adjustment were calculated...

Signal-transducing functions driven by the cytoplasmic domain of membrane type-1 matrix metalloproteinase (MT1-MMP) are believed to regulate many inflammation-associated cancer cell functions including migration, proliferation, and survival. Aside from upregulation of the inflammation biomarker cyclooxygenase-2 (COX-2) expression, MT1-MMP's role in relaying intracellular signals triggered by extracellular pro-inflammatory cues remains poorly understood. Here, we triggered inflammation in HT1080 fibrosarcoma cells with phorbol-12-myristate-13-acetate (PMA), an inducer of COX-2 and of MT1-MMP...
