Previous studies have shown that some cytokines mediate the effect of IGF-1 on inflammation and also association between IGF-1 and vascular endothelial dysfunction. Due to the discrepancies in the inflammatory and anti-inflammatory roles of IL-27 and IL-35, the effects of these cytokines and their IGF-1-mediating role were investigated regarding chronic joint inflammation and synovial blood flow.Male...
The human immunodeficiency virus (HIV) infection shows variable rate of disease progression. The underlying biological and molecular mechanisms involved in determining progression of HIV infection are not fully understood. The aims of this study were to determine plasma concentrations of active TGF β 1, Th1 and Th2 cytokines in patients with non-progressive and those with progressive HIV-1 infection,...
High Mobility Group Box-1 (HMGB1) is considered a prototype alarmin molecule. Upon its extracellular release, HMGB1 engages pattern recognition receptors and the Receptor for Advanced Glycation End-products (RAGE) followed by an outpouring of inflammatory cytokines, including interleukin (IL)-6.We assayed the amniotic fluid (AF) levels of HMGB1 and IL-6 in 255 women that either had a normal pregnancy...
Postinfluenza pneumococcal pneumonia is an important cause of global morbidity and mortality. What causes this increased susceptibility is not well elucidated. IL-35 is a newly described cytokine in infectious tolerance. A murine model was established to study postinfluenza pneumococcal pneumonia and evaluate the role of IL-35 in host defense against postinfluenza pneumococcal pneumonia. Pulmonary...
Although chemokines are critical elements for the selective attraction and activation of various leukocyte subsets in the inflammatory process, there are few findings concerning T helper (Th) 1 or Th2 chemokines in ankylosing spondylitis (AS). This study was designed to determine whether serum levels of chemokines that are preferentially chemotactic for Th1 (IFN-gamma-inducible protein-10, IP-10/CXCL10)...
There is an urgent need for new tools for the rapid diagnosis of tuberculosis (TB) disease in resource-constrained settings. Tests based on host immunological biomarkers maybe useful, especially if based on easily available samples. We investigated host biomarkers detected in saliva samples from individuals with suspected pulmonary TB disease, as tools for the diagnosis of TB disease and monitoring...
Current orthopedic therapies, aimed solely at symptomatic control, are unable to restore the cytokine imbalance that produces the hallmark clinical profile of osteoarthritis. While a myriad of chemical factors in the cytokine network stimulate local joint inflammation and pain, Interleukin 1 (IL-1) is widely recognized as a key offender and a potential therapeutic target. The purpose of this article...
Based on former studies showing an antagonism between angiopoietin-2 (Ang-2) and bacterial endotoxins (LPS), we investigated the role of Ang-2 as immunomodulatory treatment. At first, kinetics of circulating LPS in Gram-negative pyelonephritis developing after urinary obstruction was studied. Serum LPS, interleukin (IL)-6 and Ang-2 were measured in 25 patients with acute pyelonephritis and sepsis...
Staphylococcus aureus is one of the versatile Gram positive bacteria causing a range of diseases. Upon challenge, host immune cells recognize S. aureus and mount diverse immune responses including production of pro-inflammatory cytokines such as IL-1β and TNF-α. These cytokines are important mediators of inflammation which can be detected via various immunological methods such as enzyme linked immunosorbent...
Preeclampsia is associated with an increased inflammatory response. Immune suppression might be an effective treatment. The aim of this study was to examine whether Cyclosporin A (CsA), an immunosuppressant, improves clinical characteristics of preeclampsia and suppresses inflammation in a lipopolysaccharide (LPS) induced preeclampsia rat model. Pregnant rats were randomly divided into 4 groups: group...
Hemorrhage is one of the leading causes of death in patients with trauma. We recently demonstrated that resveratrol can improve cardiac function and prolong life following severe hemorrhagic injury (HI) in a rat model. The present work is focused on determining changes in NF-κB dependent gene expression in the heart and the systemic cytokine milieu following HI and the effect of resveratrol treatment...
Leishmaniases consist of a group of diseases caused by protozoan parasites of Leishmania genus. The outcome of the disease depends on the immune responses of the host as well as the pathogenicity of the strain of the parasite. In murine models, the inoculation of Leishmania major into resistant mice results in Th1 responses and recovery from the infection. However in the susceptible mice, the same...
CXCL10, the chemokine with potent chemotactic activity on immune cells and other non-immune cells expressing its receptor CXCR3, has been demonstrated to involve in myocardial infarction, which was resulted from hypoxia/ischemia. The cardiac microvascular endothelial cells (CMECs) are the first cell type which is implicated by hypoxia/ischemia. However, the potential molecular mechanism by which hypoxia/ischemia...
The study was carried out to understand the influence of IFN-γ, IL-12 and IL-10 cytokine production and expression in tuberculosis patients with diabetes mellitus (TBDM) and their household contacts (HHC).The study involved a total of 300 subjects, 50 in each category of TBDM, TBDM HHC, pulmonary tuberculosis patients (PTB), PTB HHC, DM and healthy controls (HC). TBDM, PTB and their HHC, 25 each were...
IL-5 is a Th2 cytokine which activates eosinophils and is suggested to have an atheroprotective role. Genetic variants in the IL5 locus have been associated with increased risk of CAD and ischemic stroke. In this study we aimed to identify genetic variants associated with IL-5 concentrations and apply a Mendelian randomisation approach to assess IL-5 levels for causal effect on intima-media thickness...
Microglia, the resident macrophages of the central nervous system, play a vital role in the regulation of innate immune function and neuronal homeostasis of the brain. Currently, much interest is being generated regarding the investigation of the microglial migration that results in their accumulation at focal sites of injury. Chemokines including CCL2 are known to cause the potential induction of...
To compare the ability of thyroid hormones, IL-6, IL-10, and albumin to predict mortality, and to assess their relationship in case-mix acute critically ill patients.APACHE II scores and serum thyroid hormones (FT3, FT4, and TSH), IL-6, IL-10, and albumin were obtained at EICU admission for 79 cases of mix acute critically ill patients without previous history of thyroid disease. Patients were followed...
Diabetic vascular complication is a leading cause of diabetic nephropathy, a progressive increase in urinary albumin excretion coupled with elevated blood pressure leading to declined glomerular filtration and eventually end stage renal failure. There is growing evidence that activated inflammation is contributing factor to the pathogenesis of diabetic nephropathy. Meanwhile, IL-18, a member of the...
Metabolic Syndrome prevalence has reaching epidemic proportions worldwide. Adiponectin (Acrp30), and in particular its High Molecular Weight (HMW) oligomers, contributes to enhance insulin sensitivity and to reduce inflammation levels. Physical exercise improves body’s biochemical balance and metabolism resulting effective in prevention of metabolic diseases. Whether improvement of metabolic features...
The host immune response, apart from mycobacterial factors, is a significant determinant in the development of tuberculosis (TB). The purpose of the study was to examine whether the differential serum profiles of cytokines IL-1β, IL-2, IL-4, IL-6, IL-10, IL-15, IFN-γ, TGF-β, and TNF-α could discriminate between TB patients and healthy controls and provide insights into pathogenesis. Serum samples...
