BACKGROUND AND OBJECTIVES Kawasaki disease is an acute systemic vasculitis of which pathogenesis suspected is caused by immune dysregulation. The goal of this study is to evaluate the activation pattern of T helper cell type 1 (Th1) and T helper cell type 2 (Th2) in patients with Kawasaki disease. SUBJECTS AND METHODS Prospective study of 60 patients (male 36, female 24) with diagnosis of Kaw...

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease characterized by aberrant T cell immune response. Diffuse proliferative lupus nephritis (LN-IV) is the most common, severe, and active form of lupus nephritis. In this study, we investigated the production of Th1, Th2, and Th17 cytokines in prediction of active form of LN-IV. ProcartaPlex multiplex immunoassays panels were used ...

BACKGROUND The role played by T helper cytokines under chronic, low grade inflammation as seen in type-2 Diabetes Mellitus (T2DM) and Coronary Artery Disease (CAD) co-morbidity is less well studied. In the present study, we measured the serum levels of both Th1 and Th2 cytokines and correlated it with clinical risk factors for T2DM (Insulin Resistance (IR), Glycated haemoglobin (HbA1c)) and CAD...

Type-1 and type-2 lung granulomas, respectively, elicited by bead immobilized Mycobacteria bovis and Schistosoma mansoni egg antigens (Ags) display different patterns of chemokine expression. This study tested the hypothesis that chemokine expression patterns were related to upstream cytokine signaling. Using quantitative transcript analysis, we defined expression profiles for 16 chemokines and...

T-helper (Th) cells play a central role in modulating immune responses. The Th1/Th2 paradigm has now developed into the new Th1/Th2/Th17 paradigm. In addition to effector cells, Th cells are regulated by regulatory T (Treg) cells. Their capacity to produce cytokines is suppressed by immunoregulatory cytokines such as transforming growth factor (TGF)-beta and interleukin (IL)-10 or by cell-to-ce...

Although coinfection of hepatitis B virus (HBV) and Schistosoma mansoni is a frequent event in humans, little is known about the interactions between these two pathogens. S. mansoni infection induces T helper cell type 2 (Th2)-type cytokines in the liver of humans and mice. The intrahepatic induction of nitric oxide (NO) and Th1-type cytokines, such as interferon (IFN)-gamma and IFN-alpha/beta,...

Previous studies have shown that formaldehyde (FA) could cause immunotoxicity by changing the number of T lymphocytes and that cytokines play a pivotal role in the regulation of T lymphocytes. However, the previously used cytokine detection methods are difficult to use in the measurement of several cytokines in a small amount of sample for one test. Therefore, the cytometric bead array (CBA) te...

Gérard, Anne-Catherine, Marie Boucquey, Marie-France van den Hove, and Ides M. Colin. Expression of TPO and ThOXs in human thyrocytes is downregulated by IL-1 /IFN, an effect partially mediated by nitric oxide. Am J Physiol Endocrinol Metab 291: E242–E253, 2006.

PHELA is a herbal traditional medicine that is under development for use as an immune booster in immune compromised individuals. Therefore, the aim of this study was to determine PHELA's mechanism of action by observing for changes in cytokine profiles. Four groups of Sprague Dawley rats (n = 8) were treated daily and separately with normal-saline, cyclosporine-A, PHELA-only and PHELA+ cyclospo...

is the production of IL-12 by macrophages and dendritic cells responding to antigens or direct infection immune response; transplantation [3]. Polarized Th1 cells produce IL-2, IFN-c, and lymphotoxin. These cytokines promote the development of cytotoxic T cells, which support delayed-type hypersensitivity reaction (DTH) and facilitate anti-body-dependent cellular cytotoxicity (ADCC) serving Twe...
