Objective: Helicobacter pylori has a well-established role in the development of gastric cancer. In vitro studies reveal increased proliferation of the gastric mucosa in the presence of H. pylori infection. It has been also shown that production of some cytokines, such as interleukin-1 beta (IL-1b) is in...

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-β under i...

OBJECTIVES The biological functions of transforming growth factor-β signaling that involves Smad proteins have not been previously investigated with respect to coronary artery bypass grafts. The aim of the present study was to observe the immunostaining of proteins that are related to this signaling pathway. METHODS Fifteen remnants of coronary artery bypass grafts, including nine saphenous v...

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...

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...
