results our results revealed that the serum levels of tgf-β were significantly increased in chb patients in compare to healthy controls. conclusions according to this result, it may be concluded that high serum levels of tgf-β may be a mechanism by which immune response against hbv is suppressed. background the transforming growth factor-β (tgf-β) is an important cytokine with anti-inflammatory...

Background: The multifunctional transforming growth factor beta (TGF-β) is a glycoprotein that exists in three isoforms. TGF-β3 expression increases in fetal wound healing and reduces fibronectin and collagen I and III deposition, and also improves the architecture of the neodermis which is a combination of blood vessels and connective tissue during wound healing. Fibroblasts are key ...

Introduction: Natural biomaterials and growth factors are key factors in tissue engineering. The objective of the present study was to evaluate transforming growth factor beta 1 (TGF-β1) and curcumin on proliferation and differentiation of nasal-derived chondrocyte seeded on the fibrin glue scaffold. Methods: Chondrocytes were isolated from nasal samples. Nasal-derived chon...

Background: Normal tissue toxicity continues to remain as a major challenge for radiation oncologists for delivering the total dose to the tumour cells in cancer patients. Cellular, molecular and plasma based early biomarkers to predict the overreactions and non-overreactions of normal tissue toxicity before the initiation of radiotherapy can be valuable for personalised treatment. The aim of t...

Background: Transforming growth factor-β1 (TGF-β1) has been found to play a crucial role in early central nervous system development. Several studies have illustrated decreased TGF-β1 levels in sera and brains of autistic children. Two point mutations in the TGF-β1 signal peptide at 869T/C and 915G/C have been reported to influence TGF-β1 expression. The aim of the pres...

Background and Purpose: TGF-β is a potent regulator and suppressor of the immune system and overproduction of this cytokine may contribute to immunosuppression in HIV-infected patients. Increasing population of immunosuppressed patients has resulted in increasingly frequent of fungal infections, including oral candidiasis. The aim of this study was to evaluate the plasma levels of TGF-&bet...

transforming growth factor-beta (tgf-β) is one of the most important cytokines implicated in growth, differentiation, repair and also the pathogenesis of the lung fibrosis by its stimulatory effect on extracellular matrix deposition. pulmonary epithelial cells are considered as a source of tgf-β in lung. substance p (sp), as a neuroimmunomodulator has elevated levels in inflamed airways and alt...

The effect of transforming growth factor beta (TGF beta) on proteoglycan synthesis and degradation in anatomically intact articular cartilage of murine patellae was studied. Exogenously added TGF beta up to a concentration of 200 pmol/l had no effect on proteoglycan synthesis in intact articular cartilage. Neutralisation of endogenously produced TGF beta with a specific monoclonal antibody to T...

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...

Glycolysis in normal resting rat kidney cells (NRK-49F) was stimulated by a 2-hr exposure to transforming growth factors prior to assay. Transforming growth factor beta (TGF-beta) was effective when added alone, and further addition of epidermal growth factor (EGF) had little effect. The stimulation by TGF-beta was abolished when cycloheximide was present during the incubation, suggesting that ...
