In this research, preparation of Zn0.95Ni0.04Co0.01O/PANI (polyaniline) (0.5%, 1% and 1.5% PANI) nanocomposites was performed by synthesis of pure polyaniline and adsorption of resulted organic chainson the structure of Zn0.95Ni0.04Co0.01O nano particles. The as-prepared samples was characterized by X-raydiffraction (XRD), fourier transform infrared (FTIR), field emission scan...

The transcription factor T-bet regulates the differentiation of CD4(+) T-helper type 1 (Th1) cells and represses Th2 lineage commitment. Since Th1 cells are crucial in the defense against pathogens, several studies addressed the role of T-bet in immunity to infection using T-bet knockout (T-bet(-/-)) mice. Nevertheless, it is still unclear whether T-bet is required for defense. Although vaccini...

T-bet is a transcription factor that is essential for T helper (Th)1 lineage commitment and optimal IFN-gamma production by CD4(+) T cells. We examined the role of T-bet in the development of experimental crescentic glomerulonephritis, which is induced by Th1-predominant, delayed-type hypersensitivity-like responses directed against a nephritogenic antigen. Anti-glomerular basement membrane (GB...

BACKGROUND Vaccines consisting of allergen-derived peptides lacking IgE reactivity and allergen-specific T cell epitopes bound to allergen-unrelated carrier molecules have been suggested as candidates for allergen-specific immunotherapy. OBJECTIVE To study whether prophylactic and therapeutic vaccination with carrier-bound peptides from the major birch pollen allergen Bet v 1 lacking allergen...

The bromodomain and extra-terminal (BET) family of proteins are important epigenetic regulators involved in promoting gene expression of critical oncogenes. BET inhibitors have been demonstrated to repress c-Myc expression, and were initially shown to have efficacy in a number of c-Myc-dependent hematologic malignancies. Recent studies have now revealed a broader role for BET inhibitors in hema...

T-bet is important for differentiation of cytotoxic CD8 and Th1 CD4 T cells. We have discovered that Egr2 and 3 are potent inhibitors of T-bet function in CD4 and CD8 effector T cells. Egr2 and 3 were essential to suppress Th1 differentiation in Th2 and Th17 conditions in vitro and also to control IFN-γ-producing CD4 and CD8 T cells in response to virus infection. Together with Egr2 and 3, T-be...

lta zeolite nanoparticles was successfully synthesized from clear solution under controlled conditions using hydrothermal method using tetramethyl ammonium hydroxide as a structural directing agent. the as-synthesized lta zeolite particles were characterized by powder x-ray diffraction (xrd) analysis, scanning electron microscopy (sem), fourier transform infrared (ft-ir) spectroscopy, energy di...

Allergy prevalence has increased in industrialized countries. One contributing factor could be pollution, which can cause nitration of allergens exogenously (in the air) or endogenously (in inflamed lung tissue). We investigated the impact of nitration on both the structural and immunological behavior of the major birch pollen allergen Bet v 1.0101 to determine whether nitration might be a fact...

T-bet is a master regulator for IFN-γ production and Th1 differentiation. We evaluated the roles of T-bet and IFN-γ in T cell responses in acute graft-versus-host disease (GVHD) and found that T-bet(-/-) T cells induced significantly less GVHD compared with wild-type or IFN-γ(-/-) counterparts in both MHC-mismatched and MHC-matched but minor histocompatibility Ag-mismatched models driven by CD4...
