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...

pulmonary fibrosis is a progressive disease of the lungs, which leads to death in human. it has been suggested that transforming growth factor beta 1 (tgf-β1) together with oxidative stress play a central role in the pathogenesis of the ailment. the objective of this study was to evaluate the possible curative effects of black radish, raphanus sativus l . var niger (rsn) on bleomycine (blm) -in...

Transforming growth factor-β1 (TGF-β1) has been proven to function primarily in mammalian immunobiological activity, but information regarding the immune role of TGF-β1 in teleosts is limited. In the present study, we describe the cDNA cloning and characterization of the TGF-β1 molecule in the topmouth culter. TGF-β1 is highly expressed in immune-related tissues of the culter, including the thy...

BACKGROUND/AIMS In liver fibrosis, the activation of hepatic stellate cells (HSCs) is considered as a pivotal event. It is well known that transforming growth factor-β1 (TGF-β1) is the main stimuli factor responsible for HSC activation. microRNAs (miRNAs), regulating various biological processes, have recently been shown to be involved in HSC activation. A recent study reported that deficiency ...

Aims: To evaluate the expression of transforming growth factor β1 (TGF-β1) and fibroblast growth factor 2 (FGF-2) mRNA in stromal cells in response to injury in the presence of either TGF-β1 or FGF-2. It has been shown previously that heparan sulfate proteoglycans and FGF-2 are present transiently during wound repair in vivo and that an increase in TGF-β1 mRNA is detected rapidly after injury. ...

Dendritic cells transfected with interleukin (IL)-10 and transforming growth factor-β1 (TGF-β1) enhance T cell immunity and tolerance. However, no quantitative studies have investigated the suppressive functions of immature dendritic cells (imDC) cotransfected with IL-10 and TGF-β1. The effects of imDC cotransfected with IL-10 and TGF-β1 (IL-10-TGF-β1-imDC) on immune tolerance induction in a ra...

objective(s):diabetic nephropathy is an important long-term complication of diabetes mellitus which appears to be partially mediated by an increase in secretion of transforming growth factor-β (tgf-β). fibromodulin, the small leucine-rich proteoglycan, has been proposed to be the potent tgfβ1 modulator. in this study, the therapeutic effects of recombinant adenoviral vectors expressing fibromod...

BACKGROUND Transforming growth factor (TGF)-β is known to be produced by progressor tumors and to immobilize dendritic cells (DCs) within those tumors. Moreover, although TGF-β1 has been shown to promote tumor progression, there is still no direct, in vivo evidence as to whether TGF-β1 is able to directly induce distant metastasis. METHODS To address that issue and investigate the mechanism b...

the widespread use of sulfur mustard  (sm) as a chemical warfare agent in the  past century has proved its long-lasting toxic effects. despite a lot of research over the past decades on iranian veterans, there are still major gaps in the sm literature. transforming growth  factor  (tgf-β),  a  cytokine  that  affects  many  different  cell processes,  has  an important role in the lungs of pati...
