Originally identified as a cytokine that inhibits the migration of macrophages from capillaries, MIF has now emerged to be a multifunctional factor involved in immune response, glucose and lipid metabolism. We report here the molecular characterization of porcine MIF gene, which resides on chromosome 14q21.3 and encodes 114 amino acids. Porcine MIF mRNA was found to be highly expressed in stomach,...
Inflammation is involved in development and progression of atherosclerosis. Interleukin-2 (IL-2) and interleukin-6 (IL-6) have been correlated with various cardiovascular diseases. Hyperhomocysteinemia is an important risk factor for atherosclerosis and thrombotic disease. Recent studies have demonstrated that homocysteine (Hcy) enhances productions of several pro-inflammatory cytokines. In the light...
Background: The pro-inflammatory cytokines, interleukin (IL)-18 and tumour necrosis factor-α (TNFα) may play a role in coronary heart disease (CHD). We aimed to extend data on their relationships to the risk of CHD in generally healthy populations. Methods: During 5.5years follow-up in the Fletcher Challenge general population cohort there were 256 CHD cases, and 615 controls were matched for age...
Objective: Previous studies have established that hydrolysis of LDL by Group V secretory phospholipase A 2 (GV sPLA 2 ) generates a modified particle capable of inducing macrophage foam cell formation. The aim of the present study was to determine whether GV sPLA 2 -hydrolyzed LDL (GV-LDL) produces pro-atherogenic effects in macrophages independent of cholesterol accumulation...
Tumor necrosis factor-alpha (TNF) is expressed on the cell surface as a transmembrane form (tmTNF), that can be released as a soluble form (solTNF) via proteolytic cleavage. These two types of TNF exert their biological functions by binding to one of two TNF receptors, TNFR1 or TNFR2. However, the biological function of tmTNF through these two receptors remains to be determined. Here, we generated...
Background: Several experimental studies have suggested that signal transducers and activators of transcription 1 and 4 (STAT1 and STAT4) play important roles in the regulation of mesangial proliferation and renal fibrosis, and in the development of inflammation in several types of glomerulonephritis. Methods: The present study was conducted to investigate the association between single nucleotide...
Although the role of various cytokines on stimulating the immune responses is characterized well, the importance of LIGHT, a member of TNF superfamily, is less clear. In the current study, we administrated LIGHT expression plasmid as an adjuvant to HSV-1 gB DNA vaccine. HSV-1 gB DNA can elicit vigorous humoral and cell mediated immunity in BALB/c mice. LIGHT could potentiate the proliferation of T...
Background: Th17 cells are thought to contribute to the immunopathology of allergic and autoimmune conditions. Their role in multiple sclerosis (MS) pathology remains to be fully elucidated. Objective: To assess peripheral blood Th17 responses in patients with MS compared to controls. Methods: We isolated peripheral blood mononuclear cells from 41 MS patients and 23 healthy controls, which were then...
CKβ8/CCL23 is a CC chemokine and alternative splicing of the CKβ8 gene produces two mRNAs that encode CKβ8 and its isoform CKβ8-1. Chemokines play a critical role in leukocyte trafficking and development of inflammation and chemokines are also known to be involved in cell proliferation. To investigate participation of CKβ8 and CKβ8-1 in cell proliferation, we examined the effects of CKβ8 and CKβ8-1...
Interferon-gamma (IFNγ) is a central regulator of the immune response and signals via the Janus Activated Kinase (JAK)-Signal Transducer and Activator of Transcription (STAT) pathway. Phosphorylated STAT1 homodimers translocate to the nucleus, bind to Gamma Activating Sequence (GAS) and recruit additional factors to modulate gene expression. A bioinformatics analysis revealed that greater number of...
We conducted a population-based study on 738 schoolchildren who received two doses of rubella vaccine in order to determine cytokine secretion patterns and their associations with demographic and clinical variables. The results showed a robust rubella-specific inflammatory cytokine response characterized by high median [inter-quartile range (IQR)] secretion levels (in pg/mL) of IL-6 [3681.0 (3160...
The interleukin (IL)-7 receptor (IL-7R) is expressed on human pre-B but not mature B-cells. We hypothesised that aberrant expression of IL-7R contributes to B-cell oncogenesis. Surface expression of IL-7R components CD127 and CD132, and intracellular Ki-67 and Bcl-2 were examined by flow cytometry on peripheral blood or bone marrow mononuclear cells (PBMC; BMMC) from patients with B-cell derived neoplasms,...
TGFβ1 plasma levels and TGFβ1 genetic polymorphisms have been linked to radiation-induced lung injury. As the correlation between plasma levels and genotype is not always straightforward, this study investigated the association between TGFβ1 genotype, considering several polymorphisms, and in vitro TGFβ1 secretion of human lymphocytes. Four polymorphisms in TGFβ1 (c.-800, c.-509, c.29, c.74) affecting...
Introduction: Female gender is associated with longer survival after treatment for colorectal cancer (CRC). Reasons behind this phenomenon are not entirely clear. In addition, higher interleukin-6 (IL-6) and interleukin-1 (IL-1) levels have been found to be associated with poorer prognosis in CRC patients. The aim of this study was to investigate if cytokine levels were different in male and female...
Radiotherapy (RT) produces oxidative stress and local inflammation. This study aimed at clarifying the role of different cytokines (VEGF, TNFα, IL-1β, IL-6, IL-8, IL-12 and IL-18) in bronchoalveolar lavage (BAL) fluid and in the serum of lung cancer patients at baseline and during RT. Bronchoscopy and BAL were performed on 36 lung cancer patients and 36 controls for diagnosis; patients receiving RT...
We hypothesize that higher morbidity of patients with ST-segment elevation myocardial infarction (STEMI) in the out-of-office hours differences in outcome after myocardial infarction may depend on the concentrations of inflammatory cytokines. The aim of the study was to determine the relation between the time of percutaneous coronary intervention (PCI) and local concentration of interleukin 6 (IL-6)...
Lung diseases like cystic fibrosis (CF) and chronic obstructive pulmonary disease (COPD) are associated with chronic airway inflammation. The aim of our study was to compare a complex biomarker profile in order to characterize specific inflammatory patterns in sputum of patients with CF and COPD. Induced sputum samples of 19 CF-, 26 COPD patients and 21 healthy controls were analyzed for concentrations...
A proinflammatory role of T helper (Th)17 cells, producing IL-22 and IL-17A, has been favored although there is evidence for negative immune regulation by IL-17A. Here we show that IL-22 was produced during an allergic response in lungs of mice, immunized and challenged with ovalbumin (OVA), and that IL-22 neutralization further augmented the eosinophil recruitment to the lung. In a second allergy...
B lymphocyte stimulator (BLyS), B cell activating factor (BAFF), a member of the tumor necrosis factor ligand superfamily has potent co-stimulatory activity on B cells, and BLyS-production in the airway mucosa is of potential importance as it triggers innate and adaptive immune responses. To investigate whether airway fibroblast could express BLyS, we examined BLyS-expression in human nasal airway...
