Outside pregnancy, both obesity and diabetes mellitus are associated with changes in inflammatory cytokines. Obesity in pregnancy may be complicated by gestational diabetes mellitus (GDM) and/or fetal macrosomia. The objective of this study was to determine the correlation between maternal cytokines and fetomaternal adiposity in the third trimester in women where the important confounding variable...
We concentrated on the complication-free phase of juvenile onset type 1 diabetes mellitus (T1DM) searching for associations between concentration of inflammatory factors TNF-α, CRP and VEGF and two monocyte subsets the CD14 ++ CD16 − and CD14 + CD16 + . We analysed a randomly selected group of 150 patients without complications (disease duration 2.74±2.51years) at the...
Systemic inflammatory conditions, as seen in obesity and in the metabolic syndrome, are associated with high plasmatic levels of proatherogenic and prothromboticadipokines and low levels of adiponectin. Inhibitors of HMG-CoA reductase have beneficial effects in reducing cardiovascular events attributed predominantly to its lipid-lowering effects and recent studies suggest that these effects might...
TLR recognition activates the secretion of pro- and anti-inflammatory cytokines and it also modulates the expression of crucial molecules involved in phagocytosis and antimicrobial activity. Scavenger receptors can act as TLR co-receptors or facilitate antigen loading. However, it remains unknown whether TLR can modulate the expression of these scavenger receptors. We stimulated human peripheral blood...
Interleukin 22 (IL-22), a relatively new cytokine has been found to induce significant proliferation of human keratinocytes and fibroblast like synoviocytes (FLS) and thus plays an important role in the pathogenesis of autoimmune diseases like psoriasis and rheumatoid arthritis (RA) which are characterized by hyperproliferation of keratinocytes and FLS respectively. PI3K/Akt/mTOR signaling cascade...
Interleukin-10 (IL-10) has been described as an anti-inflammatory cytokine and IL-10 gene polymorphisms was associated with altered interleukin-10 levels, therefore, we aimed to conduct a meta-analysis assessing the association of IL-10 genetic polymorphisms with the risk of both chronic periodontitis (CP) and aggressive periodontitis (AgP). Electronic databases were acquired from PubMed, Embase,...
Adaptive immunity depends on the production and maintenance of a pool of mature peripheral lymphocytes throughout life. The signals regulating the survival of mature splenic B cells have become a major focus in recent studies of B cell immunology. Lasting B cell persistence in the periphery is dependent on survival signals that are transduced by cell surface receptors. Cytokines have been shown to...
Exposure to secondhand smoke (SHS) is associated with morbidity in children. Alterations in immune responses may explain this relationship, but have not been well-studied in children. Our objective was to determine the association between SHS exposure and serum cytokine levels in healthy children.We recruited 1–6year old patients undergoing routine procedures. A parent interview assessed medical history...
Heparins, including unfractionated heparin (UFH) and low-molecular-weight heparins (LMWH), are glycosaminoglycans that are largely used as anti-thrombotic drugs. While the mechanisms of their anticoagulant actions in blood have been extensively studied, their effects on the inflammation of the endothelium are still under investigation since the endothelium plays a central role in sepsis. Furthermore,...
1,25 Dihydroxy vitamin D 3 (vitamin D 3 ) is an immunomodulator and its deficiency has been associated with susceptibility to tuberculosis. We have studied the immunoregulatory role of vitamin D 3 on various chemokine expression in pulmonary tuberculosis. Peripheral blood mononuclear cells obtained from 21 pulmonary tuberculosis (PTB) patients and 24 healthy controls (HCs)...
The immunoregulatory effects of granulocyte colony-stimulating factor (G-CSF) on allogeneic peripheral blood cell transplantation (PBCT) have been demonstrated to reduce acute graft-versus-host disease (GVHD). However, the underlying mechanism is still not clear. In this study, we focused on the direct effects of G-CSF on donor CD4 + T cell responses after transplantation. We observed that...
Mycobacterium tuberculosis (MTB) remains a leading infectious threat to human health. Macrophages are the cells targeted for infection by the bacterium as well as key effector cells for clearance of the pathogen. Interleukin (IL)-27 opposes macrophage-mediated control of MTB because supplying IL-12 and blocking the activity of IL-27 limits bacterial growth in primary human macrophages. The purpose...
Management of sepsis in critically ill patients remains difficult and requires prolonged intensive care. Genetic testing has been proposed as a strategy to identify patients at risk for adverse outcome of critical illnesses. Therefore, we wished to determine the influence of heredity on predisposition to poor outcome and on duration of ventilator support of intensive care unit (ICU) patients.A study...
The mechanism responsible for the decrease in vitamin D status (i.e., plasma or serum 25-hydroxyvitamin D (25(OH)D) concentration) during inflammatory stress is unknown in humans. Interferon (IFN)-γ is an inflammatory cytokine that regulates vitamin D metabolism in isolated immune cells, but data suggesting this regulation exists in vivo is lacking. The purpose of this study, therefore, was to associate...
Interleukin (IL)-23 is an essential cytokine involved in the expansion of a novel CD4 + T helper subset known as Th17, which has been implicated in the pathogenesis of periodontitis recently. Our previous study first identified specialized human periodontal ligament fibroblasts (hPDLFs) as an important production source of IL-23. The present study was undertaken to investigate the effects...
Type I interferons (IFN-α/β) serve as the first line of defense against viral infection and share the same type I IFN receptor (IFNAR) complex, which is composed of IFNAR1 and -2. The Eastern woodchuck (Marmota monax) and Chinese woodchuck (Marmota himalayana) are suitable for studying hepatitis B virus (HBV) infection. Here, the complete or partial sequences of the IFNARs of both species were obtained...
Thrombopoietin (TPO) plays an important role in injuries of different tissues. However, the role of TPO in acute pancreatitis (AP) is not yet known. The aim of the study was to determine the involvement of TPO in AP. Serum TPO was assayed in necrotizing pancreatitis induced by l-arginine in mice. Recombinant TPO and anti-TPO antibody were given to mice with necrotizing pancreatitis. Amylase, lipase,...
Recent studies suggest a powerful prognostic value for blood cytokine levels in different diseases. Non-Hodgkin lymphoma (NHL) still represents one of the main causes of death in the HIV setting, with a wide variation in outcome and survival among patients.We measured blood concentrations of 11 cytokines from HIV–NHL patients at diagnosis and correlated these with the patient outcome to evaluate the...
Th17 cells play a crucial role in host immune response. We examined the role of Th17 cells in HIV-1 ‘subtype-C’ infection and report that HIV-1 specific Th17 cells are induced in early infection and slow progressors but are significantly reduced at late stage of infection. There was a further decline in Th17 cells in late stage subjects with gastrointestinal infections. Additionally, we observed expanded...
