OBJECTIVE Subclinical inflammation leads to insulin resistance and beta-cell dysfunction. This study aimed to assess whether levels of circulating transforming growth factor-beta1 (TGF-beta1)-a central, mainly immunosuppressive, and anti-inflammatory cytokine-were associated with incident type 2 diabetes. RESEARCH DESIGN AND METHODS We measured serum levels of TGF-beta1 from 460 individuals w...

Late-onset Alzheimer's disease (LOAD) is the most common form of dementia in the elderly. LOAD has a complex and largely unknown etiology with strong genetic determinants. Genetics of LOAD is known to involve several genetic risk factors among which the Apolipoprotein E (APOE) gene seems to be the major recognized genetic determinant. Recent efforts have been made to identify other genetic fact...

an appropriate differentiation of distinct human cd4+ t cell subset is critical for manipulating these cells for using in immunity related diseases. despite various attempts to clarify the role of different factors involved in th17 differentiation, many crucial contradictions yet remained to be optimized. although it has been shown that the differentiation of in-vitro th17 cells culture conditi...

Abstract Background and Aims The transforming growth factor-β1 (TGF-β1) is a pleiotropic cytokine, with distinct roles both in fibrosis inflammation acts through the Smad signalling renal injury. We sought expression of TGF-β1/Smad ANCA associated glomerulonephritis (AAGN) we assessed this correlation injury at diagnosis as well progression. Method evaluated immunohistochemical TGF-β1, phosphor...

some of the genotypes of cytokines are associated with acute graft versus host disease after bone marrow transplantation. the purpose of the present investigation was to find out the possible association between transforming growth factor beta-1 (tgf-β1) codon 25 polymorphism (rs:1800471) and acute graft versus host disease (agvhd) after bone marrow transplantation from the sibling with the sim...

objectives in this study, the association of tgf-β1 +915g/c and -509c/t gene polymorphisms with chronic hepatitis b was evaluated in iranian patients. materials and methods a population-based case–control study was conducted in taleghani hospital, tehran. a number of 220 patients with chronic hepatitis b and the same number of healthy control subjects were designated the case and the control gr...

The TGF-␤ family comprises many cytokines involved in the control of cell fate (1). Some of these have been shown to control cell death. For instance, at least one of the members of the BMP subfamily of the TGF-␤ family is required in interdigital death, a classical model of developmentally programmed cell death (2). Another TGF-␤ family member, TGF-␤ 1, entertains a complicated relationship wi...

Mesangial cells are the main source of renal interstitial fibrosis in diabetic nephropathy (DN). Interferon-γ (IFN-γ) is a key cytokine that may play a potential therapeutic role in reducing fibrosis. Here, we focus on the effects of IFN-γ on human mesangial cells (HMCs) treated with high glucose. This study shows that IFN-γ phosphorylates STAT1, suppresses HMC proliferation, and downregulates ...

Extracellular matrix synthesis and remodelling are driven by increased activity of transforming growth factor beta 1 (TGF-β1). In tendon tissue repair, increased activity of TGF-β1 leads to progressive fibrosis. Decorin (DCN) and interleukin 10 (IL-10) antagonise pathological collagen synthesis by exerting a neutralising effect via downregulation of TGF-β1. Herein, we report that the delivery o...
