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...

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...

conclusions based on our study, in vivo prepared e/sa may be considered as a good candidate for animal immunization. results our results showed that the serum levels of anti-e/sa immunoglobulins significantly increased in all of the immunized groups. the differences of the serum levels of tgf-β between the groups were statistically significant at days 28 and 56 after immunization with e/sa. bac...

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 present study was to investig...

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...

background: successful pregnancy in allopregnant women depends upon the control of graft rejection mechanisms. it has been suggested that some immunosuppressive cytokines contribute to successful pregnancy and transplantation. transforming growth factor beta (tgf-   β) exhibits potent immunoregulatory and anti-inflammatory properties which might prolong graft survival. recent studies suggest a ...

transforming growth factor beta (tgf-b) is a mediator released by nearly all cell types. it has suppression activity on the immune system, but exactly how this effect is carried out is not clear. previous experiments showed that igg interacts with or carriers active tgf-b, that could suppresses cytotoxic t-cell responses to an immunogenic tumor in mice. since t cell receptor (tcr) has structura...
