Objective(s): Allergic rhinitis (AR) is a common hypersensitivity disease worldwide. Immunotherapy has been performed as the best treatment for years. This study aimed to study the gene expression pattern of immune system cells following an accelerated rush immunotherapy protocol (ARIT) in patients with AR.Materials and Methods: Fifteen ...

Background: Pre-eclampsia is a multifactorial pregnancy specific vascular disorder characterized by hypertension and proteinuria. It affects around 3-5% pregnancies worldwide. The aetiology and pathophysiology of PE remain poorly understood. But it is generally accepted defective placentation during the early stage of pregnancy most likely in combination with maternal and environmental factors ...

atherosclerosis is a chronic inflammatory condition that affects the arterial wall. oxidized low- density lipoprotein (ox-ldl) seems to have an important role in atherosclerotic plaque formation. this study was performed to investigate the effects of ox-ldl as well as pha on proliferation and gene expression of  peripheral blood  mononuclear  cells (pbmcs) in patients with atherosclerosis compa...

Regulatory T cells (Tregs) participate in the negative regulation of inflammatory reactions by suppressing effector cells. In a number autoimmune disorders, suppressive function and/or Tregs is compromised. The lack active functioning can be restored with adoptive transfer expanded ex vivo autologous Tregs. our study, we traced differentiation and maturation CD4+CD25+FoxP3+CD127low over 7 days ...

CD4(+)CD25(+) regulatory T (Treg) cell lineage commitment and expression of the transcription factor Foxp3 can be induced at the CD4(+)CD8(+) double-positive (DP) and CD4(+)CD8(?) single-positive stages of thymic development, as well as in postthymic CD4(+) T cells in peripheral lymphoid tissues. The availability of transgenic mice with Foxp3-dependent fluorochrome reporter gene expression has ...

FOXP3 is an X-linked tumor suppressor gene and a master regulator in T regulatory cell function. This gene has been found to be mutated frequently in breast and prostate cancers and to inhibit tumor cell growth, but its functional significance in DNA repair has not been studied. We found that FOXP3 silencing stimulates homologous recombination-mediated DNA repair and also repair of γ-irradiatio...

Background: Atherosclerosis is a chronic inflammatory disease affecting large and medium arteries. CD4+ T cells are known to play a role in the progression of the disease. CD4+CD25+Foxp3+ natural Treg (nTreg) cells seem to have a protective role in the disease and their reduction in acute coronary syndrome is recently shown. Objective: To investigate the frequency of nTreg subsets in the pe...

Considerable evidence supports the prediction that CD25 is directly regulated by the forkhead transcription factor FOXP3. However, given that CD25 is normally upregulated in activated T cells, regardless of whether they express FOXP3, this issue has still to be definitively demonstrated. Here we describe that FOXP3, induced by CD28 signals in human CD4(+)CD25(-) T lymphocytes, synergizes with R...

FOXP3 is a lineage-specific transcription factor that is required for regulatory T cell development and function. In this study, we determined the crystal structure of the FOXP3 forkhead domain bound to DNA. The structure reveals that FOXP3 can form a stable domain-swapped dimer to bridge DNA in the absence of cofactors, suggesting that FOXP3 may play a role in long-range gene interactions. To ...
