Glucocorticoids (GCs) immunosuppression acts via regulation of several transcription factors (TF), including activating protein (AP)-1, NF-kappaB, and NFAT. GCs inhibit Th1 cytokines and promote a shift toward Th2 differentiation. Th1 phenotype depends on TF T-bet. In this study, we examined GC regulation of T-bet. We found that GCs inhibit T-bet transcriptional activity. We show that glucocort...

adsorption of bovine serum albumin (bsa) onto calcium hydroxyl apatite (ha), ca10po4(oh)2, has been studied by ultra violet (uv) spectroscopy. the adsorption isotherms of bsa onto the ha surface at 291.7 k and 303.2 k were satisfactorily presented by langmuir equation and the evaluated parameters are reported. the specific surface area of ha has been measured by the bet method. the obtained val...

A T-box-containing protein expressed in T cells (T-bet) is a key transcription factor involved in the regulation of Th cell differentiation. Although T-bet-deficient CD4(+) T cells fail to produce IFN-γ and typically differentiate into Th2 cells in vitro, ectopic overexpression of T-bet elevates IFN-γ and suppresses production of IL-2 and Th2 cytokines through different mechanisms. Despite the ...

The past decade has seen an escalating enthusiasm to comprehend chronic tinnitus from the perspective of both scientific understanding and clinical management. At the same time, there is a significant interest and commercial investment in providing targeted and individualized approaches to care, which incorporate novel sound-based technologies, with standard audiological and psychological strat...

BACKGROUND Characterization of IgE-binding epitopes of allergens and determination of their patient-specific relevance is crucial for the diagnosis and treatment of allergy. OBJECTIVE We sought to assess the contribution of specific surface areas of the major birch pollen allergen Bet v 1.0101 to binding IgE of individual patients. METHODS Four distinct areas of Bet v 1 representing in tota...

The complex relationship between Th1 and Th17 cells is incompletely understood. The transcription factor T-bet is best known as the master regulator of Th1 lineage commitment. However, attention is now focused on the repression of alternate T cell subsets mediated by T-bet, particularly the Th17 lineage. It has recently been suggested that pathogenic Th17 cells express T-bet and are dependent o...

BACKGROUND Previous data showed that the predominance of intraglomerular T-bet or GATA3 is correlated with different mechanisms of rejection, suggesting that the ratio of T-bet/GATA3 might be used to distinguish antibody-mediated rejection (ABMR) and T-cell-mediated rejection (TCMR). METHODS We compared the intraglomerular T-bet/GATA3 ratio in ABMR and TCMR. The intragraft expression of T-bet...

Experimental autoimmune myocarditis (EAM) appears after infectious heart disease, the most common cause of dilated cardiomyopathy in humans. Here we report that mice lacking T-bet, a T-box transcription factor required for T helper (Th)1 cell differentiation and interferon (IFN)-gamma production, develop severe autoimmune heart disease compared to T-bet+/+ control mice. Experiments in T-bet-/- ...

Background/Aims Balloon expulsion test (BET) is regarded as a screening tool of dyssynergic defecation (DD). However, some patients with normal BET results may be treated effectively by biofeedback training. This study aims to validate BET as a single screening test. Methods Two hundred and thirty-two patients who were diagnosed with functional constipation or irritable bowel syndrome with co...

T-bet is a critical transcription factor that regulates differentiation of Th1 cells from CD4(+) precursor cells. Since T-bet directly binds to the promoter of the IFN-γ gene and activates its transcription, T-bet deficiency impairs IFN-γ production in Th1 cells. Interestingly, T-bet-deficient Th cells also display substantially augmented the production of IL-2, a T cell growth factor. Exogenou...
