The aim of this study is to investigate the correlation between E400A polymorphisms of interleukin-4 receptor α chain (IL-4Rα) and lipid metabolism. Genomic DNA from 121 type 2 diabetes mellitus (T2DM) patients and 113 non-diabetic, non-obese control study subjects were extracted, and their IL-4Rα E400A polymorphisms were analyzed by PCR-RFLP. The correlation between IL-4Rα E400A genotypes and study...
It has been widely reported that Interleukin-6 (IL-6) is overexpressed in the serum and ascites of ovarian cancer (OVCA) patients, and elevated IL-6 level correlates with poor prognosis and survival. However, the exact role that IL-6 plays in this malignancy or whether IL-6 can regulate tumorigenic properties has not been established. Here we demonstrate that overexpression of IL-6 in non-IL-6-expressing...
Published data describing the association between CYP1A1 MspI gene polymorphism and lung cancer risk are inconclusive. To determine a more conclusive relationship, we performed an updated meta-analysis of all eligible studies and conducted the subgroup analysis by stratification according to the ethnicity source, histological types of lung cancer, gender and smoking status of case and control populations...
Tacrolimus (FK506, Prograf®) is an orally available, T cell specific and anti-inflammatory agent that has been proposed as a therapeutic drug in rheumatoid arthritis (RA) patients. It has been known that T cells have a critical role in the pathogenesis of RA. Recent studies suggest that Th17 cells, which mainly produce IL-17, are involved in many autoimmune inflammatory disease including RA. The present...
Multiple human breast and rat mammary carcinoma susceptibility (Mcs) alleles have been identified. Wistar Kyoto (WKY) rats are resistant to developing mammary carcinomas, while Wistar Furth (WF) females are susceptible. Gene transcripts at Mcs5a1, Mcs5a2, and Mcs5c are differentially expressed between resistant WKY and susceptible WF alleles in immune-system tissues. We hypothesized that immune-related...
Parasitic helminths are well-known to have the ability to modulate host immune responses. In this study, we investigated the fundamental immunoregulatory mechanism of the liver fluke Clonorchis sinensis (C. sinensis) using a murine macrophage RAW 264.7 (RAW) cell line and mouse bone marrow derived macrophages (BMDMs). We found that C. sinensis crude antigen (CA) is able to differentiate macrophage...
Until now, no data are present in literature about the prototype Th1 chemokine (C–X–C motif) ligand 10 (CXCL10) in anaplastic thyroid cancer (ATC).This study aimed to test in “primary human ATC cells” (ANA) vs “normal thyroid follicular cells” (TFC): (a) CXCL10 secretion basally and after interferon (IFN)-γ and/or tumor necrosis factor (TNF)-α stimulation; (b) peroxisome proliferator-activated receptor...
Toll-like receptors induce a complex inflammatory response that can function to alert the body to infection, neutralize pathogens and repair damaged tissues. Toll-like receptors are expressed on kupffer, endothelial, dendritic, biliary epithelial, hepatic stellate cells, and hepatocytes in the liver. The endoplasmic reticulum (ER) is a central organelle of eukaryotic cells that exists as a place of...
The efficacy of infliximab (IFX) has validated the role of TNF-α in the immunopathogenesis of Crohn’s disease (CD). However, antibodies to IFX emerge, which impair its efficacy. This study investigated factor(s) associated with the loss of response (LOR) to IFX and how IFX non-responders may be treated.Seventy-four patients, 36 IFX responders (GI) and 38 with LOR (GII) were included. Trough IFX level,...
Published data on the association between interleukin-4 (IL-4) rs2243250 (C-589T) polymorphism and asthma susceptibility are inconclusive. To derive a more precise estimation of the relationship, a meta-analysis was performed. A total of 17 studies with 3037 asthma patients and 3032 healthy controls were included. Overall, significantly elevated asthma risk was associated with IL-4 T allele when all...
Chagas disease is a parasitic infection that is a significant public health problem in Latin America. The mechanisms responsible for susceptibility to the infection and the mechanisms involved in the development of cardiac and digestive forms of chronic Chagas disease remain poorly understood. However, there is growing evidence that differences in susceptibility in endemic areas may be attributable...
Interleukin 6 (IL-6) is pleiotropic cytokine playing an important role in inflammatory response. Other than classical immune tissues, IL-6 is also produced in muscle cells under specific conditions. Four-and-a-half LIM-only protein 2 (FHL2) is preferentially expressed in skeletal and cardiac muscle cells compared to other tissues indicating it has an important role in skeletal muscle and cardiovascular...
Since ingredients of peri-implant sulcus fluid (PISF) may be related to the bony structure surrounding dental implants, analyze of specific markers related to bone resorption in PISF seems to be suitable for long term monitoring of peri-implant health. It is suggested that analysis of PISF may serve for detection of inflammation. The aim of this study is to analyze PISF interleukin-1 beta (IL-1β),...
The liver is a major target of injury in obese patients. Non-alcoholic fatty liver disease (NAFLD) is present in 60–90% of obese Americans and can range from simple steatosis to the more severe non-alcoholic steatohepatitis (NASH). The onset of a chronic inflammatory reaction marks the progression from simple steatosis to NASH and the expansion of adipose tissue is strongly associated with angiogenesis...
Several studies indicate a weakening of cell-mediated immunity (CMI) and reactivation of latent herpes viruses during spaceflight. We tested the hypothesis that head-down bed rest (HDBR), a ground-based analog of spaceflight, mimics the impact of microgravity on human immunity. Seven healthy young males underwent two periods of 3weeks HDBR in the test facility of the German Aerospace Center. As a...
To establish an in vitro model to study the role of keratocytes in corneal chemical burns and to investigate the interaction between chemically injured keratocytes and human peripheral blood mononuclear cells (PBMCs).Human keratocytes, epithelial cells, and PBMCs were cultured. The PBMC stimulation assay was then performed using cultured human keratocytes, epithelial cells, and NaOH-treated keratocytes...
CXCL10 is part of the group of interferon-stimulated genes and it plays an important role during different viral infections by inducing cell activation, chemotaxis and lymphocyte priming toward the Th1 phenotype. In this study, we investigated in vitro the effects of CXCL10 in activated human primary T lymphocytes in terms of apoptosis or survival, and delineated the signaling pathways that are involved...
The regulation of local l-tryptophan concentrations by tryptophan-degrading enzyme, indoleamine 2,3-dioxygenase (IDO) induced by various stimuli such as interferon-γ (IFN-γ) is one of the key mechanisms in antimicrobial effect. Recently, IDO is also focused on an immunosuppressive mechanism shared by several different immune cell types. Here, we show that inhibition of increased IDO activity maybe...
