The purpose of the present study was to examine the immediate and prolonged immune response in circulating cytokine and adipocytokine concentrations after two different resistance exercise bouts: hypertrophic (HYP1, 5 × 10, 80% of 1RM) and maximal explosive (POW1, 10 × 5, 60% of 1RM) resistance exercise bouts and how 12 weeks of resistance training (RT) modifies these responses (HYP2, POW2). Eight men completed the study. RE-induced interleukin-6 (IL-6), interleukin-1β (IL-1β), interleukin-1 receptor antagonist (IL-1ra), monocyte-chemoattractant protein-1 (MCP-1), leptin, resistin, and adiponectin were measured before (PRE) and immediately (POST0), 24 (POST24) and 48 (POST48) hours after RE bouts before and after RT...

Context: Low-grade inflammation is involved in the development of type 2 diabetes and cardiovascular disease (CVD); however, prospective studies evaluating inflammatory markers as predictors of changes in insulin secretion and insulin sensitivity are lacking. Objective: We investigated the associations of glycoprotein acetyls (GlycA), interleukin-1 receptor antagonist (IL-1RA), and high-sensitivity C-reactive protein (hs-CRP) with insulin secretion, insulin sensitivity, incident type 2 diabetes, hypertension, CVD events, and total mortality in the prospective Metabolic Syndrome in Men (METSIM) study...

Advanced glycation end products (AGEs) are involved in osteopenia in people with diabetes and the elderly. Interleukin-6 (IL-6) and vascular endothelial growth factor-A (VEGF-A) are potent regulators of bone metabolism, and in bone tissue, osteocytes are an important source of these regulators. However, whether AGEs can directly regulate IL-6 and VEGF-A secretion by osteocytes is unknown. In this study, we evaluated the effect of AGEs on IL-6 and VEGF- A production as well as apoptosis in osteocyte-like MLO-Y4 cells...

BACKGROUND: Older adults are more susceptible to higher inflammatory levels and depression. Moreover, diet may influence inflammation as well as depression but no previous study examined whether inflammatory dietary patterns are related to depression in an older population. To investigate the longitudinal association between inflammatory dietary patterns (using reduced rank regression (RRR)) and depressive symptoms in a population sample of Italian older adults. METHODS: We included 827 participants (aged≥65years) at baseline in 1998...

Follicular regulatory T (Tfr) cells from lymph node germinal centers control follicular helper T (Tfh) cell-dependent B cell activation. These scarce cells, often described and purified as CD25(+) cells, are thought to be derived from thymic regulatory T (Treg) cells. However, we observed that mouse Tfr cells do not respond to interleukin-2 (IL-2), unlike Treg cells. Stringent immunophenotyping based on B cell lymphoma 6 (Bcl6), programmed cell death protein 1 (PD-1), and CXCR5 expression revealed that Tfr cells are actually CD25(-), in mice and humans...

OBJECTIVE: The interleukin-1 receptor antagonist (IL-1RA) contributes to tumor survival and progression in multiple cancer entities. IL-1RA polymorphisms influence IL-1RA expression patterns and function. A known polymorphism was correlated with clinical outcomes in melanoma patients with particularly aggressive disease. METHODS: DNA of 343 controls and 97 melanoma patients with poor prognostic indicators (time from diagnosis to death, nodal status, metastasis) was analyzed for a variable number of tandem repeat polymorphisms (VNTR) of the IL-1RA gene...

INTRODUCTION: Acute gout occurs in people with chronic kidney disease, who are commonly older people with comorbidities such as hypertension, heart disease and diabetes. Potentially harmful treatments are administered to these vulnerable patients due to a lack of clear evidence. Newly available treatment that targets a key inflammatory pathway in acute gout attacks provides an opportunity to undertake the first-ever trial specifically looking treating people with kidney disease. This paper describes the protocol for a feasibility randomised controlled trial (RCT) comparing anakinra, a novel interleukin-1 antagonist versus steroids in people with chronic kidney disease (ASGARD)...

Oxidative stress after burn injury induces inflammatory and hypermetabolic responses associated with adverse outcomes. We propose that antioxidant and trace element supplementation may reduce oxidative stress and subsequently alleviate inflammation and hypermetabolism, thus improving clinical outcomes. We conducted a cohort study of adult patients with an acute burn injury admitted to our provincial burn center. Patients in the antioxidant group received an intravenous infusion of multivitamins and trace elements for the first 14 days after admission...

BACKGROUND: There is evidence that major depression (MDD) and bipolar disorder (BD) are accompanied by activated immune & oxidative (I&O) pathways. METHODS: To compare I&O biomarkers between MDD and BD we assessed serum levels of thiobarbituric acid reactive substances (TBARS; a lipid peroxidation marker), soluble interleukin-2 receptor (sIL-2R), sIL-6R, IL-α, sIL-1R antagonist (sIL-1RA), tumor necrosis factor receptor 60kDa/80kDa (sTNFR60/R80) in 114 MDD and 133 BD patients, and 50 healthy controls...

Soman (GD) exposure results in status epilepticus (SE) that leads to neurodegeneration, neuroinflammation, and behavioral consequences including learning and memory deficits. The neuroinflammatory response is characterized by the upregulation of the pro-inflammatory cytokine, interleukin-1 (IL-1), which mediates the expression of other neurotoxic cytokines induced after GD exposure. However, the specific role of IL-1 signaling has not been defined in terms of the consequences of GD-induced SE. Therefore, the purpose of this study was to regulate IL-1 signaling and study the behavioral deficits and neurodegeneration that occur after convulsion onset...

OBJECTIVE: Vascular calcification (VC) is an important predictor of cardiovascular morbidity and mortality. Osteogenic differentiation of vascular smooth muscle cells (VSMCs) is a key mechanism of VC. Recent studies show that IL-18 (interleukin-18) favors VC while TRPM7 (transient receptor potential melastatin 7) channel upregulation inhibits VC. However, the relationship between IL-18 and TRPM7 is unclear. We questioned whether IL-18 enhances VC and osteogenic differentiation of VSMCs through TRPM7 channel activation...

The IL-1 family member IL-36α has proinflammatory and pathogenic properties in psoriasis. IL-36α binds to the IL-36 receptor leading to nuclear factor kappa B/mitogen activated protein kinase mediated cytokine release. The IL-36R antagonist prevents recruitment of IL-1 receptor accessory protein and therefore IL-36-dependent cell activation. In inflamed human tissue, we previously could show that resident B cells and plasma cells (PC) express IL-36α. Further, fibroblast-like synoviocytes (FLS) produced proinflammatory cytokines upon IL-36α-stimulation...

Interleukin (IL)-36 cytokines are new members of the IL-1 family, which include pro-inflammatory factors, IL-36α, IL-36β and IL-36γ, and a natural receptor antagonist IL-36Ra. Over recent years, much has been learned on their important functions in the regulation of immune response and, especially, on their role in many inflammatory skin diseases. However, to date, no data have been reported on their possible involvement in acne and hidradenitis suppurativa (HS). Here, we have shown that IL-36α, IL-36β, and IL-36γ are increased in lesional skin of acne and HS, highlighting their possible pathogenetic contribution to these two skin conditions...

Cyclooxygenase-2 (COX-2) triggers pro-inflammatory processes that can aggravate neuronal degeneration and functional impairments in many neurological conditions, mainly via producing prostaglandin E2 (PGE2) that activates four membrane receptors, EP1-EP4. However, which EP receptor is the culprit of COX-2/PGE2-mediated neuronal inflammation and degeneration remains largely unclear and presumably depends on the insult types and responding components. Herein, we demonstrated that COX-2 was induced and showed nuclear translocation in two neuronal cell lines - mouse Neuro-2a and human SH-SY5Y - after treatment with neurotoxin 6-hydroxydopamine (6-OHDA), leading to the biosynthesis of PGE2 and upregulation of pro-inflammatory cytokine interleukin-1β...

Asthma is a heterogeneous disease, usually characterized by chronic airway inflammation. Most patients with asthma can be well-controlled with inhaled corticosteroids and, if necessary, the addition of a long-acting beta agonist. Despite these therapies, 5% to 10% of patients with asthma have severe, uncontrolled asthma. Selecting patients based on peripheral eosinophil counts and a history of exacerbations has led to significant decreases in exacerbations and an improvement in asthma control with medications that target IL-4, IL-5 and IL-13/...
