Salivary transforming growth factor alpha in patients with Sjögren's syndrome and reflux laryngitis.
INTRODUCTION Saliva plays a key role in the homeostasis of the digestive tract, through its inorganic components and its protein growth factors. Sjögren's syndrome patients have a higher prevalence of gastroesophageal reflux disease and laryngopharyngeal reflux. Decreased salivary transforming growth factor alpha levels were observed in dyspeptic patients, but there have been no studies in pati...
This review describes the discovery and initial characterization of the epidermal growth factors (EGFs) and transforming growth factors alpha (TGF alpha), the biosynthesis and tissue distribution of these molecules and a brief description of the effects of these molecules in culture and animals. An analysis of the similarities between the EGFs and TGF alpha s from different organisms is used to...
Effect on the canine Eck fistula liver of intraportal TGF-beta alone or with hepatic growth factors.
Transforming growth factor-beta canceled the hepatocyte proliferation caused by transforming growth factor-alpha when the two substances were mixed and administered through a disconnected central portal vein branch after creation of an Eck fistula. In contrast, transforming growth factor-beta had no antidotal action on the stimulatory effects of insulin or full test doses of insulinlike factor-...
Transforming growth factor alpha (TGF-alpha) is a pleuripotential cytokine with diverse biological effects, including the ability to influence the proliferation of normal cells or neoplastic epithelial cells. Eosinophils are a subset of granulocytes that normally enter the peripheral tissues, particularly those beneath gastrointestinal, respiratory, and urogenital epithelium, where they reside ...
The effects of exogenously added transforming growth factor (TGF alpha and TGF beta on the growth of BALB/MK cells were examined. TGF alpha supplanted the epidermal growth factor (EGF) requirement in these cells. In contrast, TGF beta reversibly inhibited the growth of BALB/MK cells by abrogating the stimulatory actions of EGF or TGF alpha. The inhibitory effects of TGF beta appeared to be medi...
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...
oral lichen planus (olp) is a chronic inflammatory disease of the oral mucosa which is considered by the world health organization (who) as a premalignant condition. one step in malignant development is so called epithelial mesenchymal transition (emt), a process whereby epithelial cells acquire mesenchymal characteristics. a factor known to induce emt is the transforming growth factor-β (tgf-β...
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...
