Suppressive Mechanisms Induced by Tregs in Celiac Disease

Celiac disease (CD) is a systemic immune-mediated disorder caused by the dietary gluten in individuals who are genetically susceptible to the disease. In fact, CD is a T cell-mediated immune disease in which gluten-derived peptides activate the lamina propria CD4+ Teff cells, and these T-cell subsets can cause the intestinal tissue damages. Also, there are additional subsets of CD4+ T cells wit...

Human Leukocyte Antigen-G Expression on Dendritic Cells Induced by Transforming Growth Factor-β1 and CD4+ T Cells Proliferation

Background: During antigen capture and processing, mature dendritic cells (DC) express large amounts of peptide-MHC complexes and accessory molecules on their surface. DC are antigen-presenting cells that have an important role in tolerance and autoimmunity. The transforming growth factor-beta1 (TGF-β1) cytokine has a regulatory role on the immune and non-immune cells. The aim of this study is ...

بررسی سلول‌های T تنظیمی CD4+CD25+FOXP3+ در محیط تومور کارسینوم مجرایی مهاجم پستان و گروه شاهد

Aim and Background: it seems that population of regulatory T cells increases in many malignancies leading to suppression of effector immune responses and thereby to progression of the disease. We aimed to assess infiltration of the regulatory T cells into tumor environment in women with breast carcinoma. Methods: in a control-case study, 9 malignant tumor tissues from invasive intraductal breas...

Expansion of CD4+CD25+FoxP3+ Regulatory T Cells in Chronic Hepatitis C Virus Infection

Background: Regulatory T cells (Tregs) have been involved in impaired immunity and may have a pivotal role in persistence of viral infections. Objective: To develop a simple and reliable in-house three color flow cytometery of peripheral blood to understand the role of HCV infection in the increase of Tregs. Methods: The level of naturally occurring CD4+CD25+FoxP3+ regulatory T cells (nTregs) i...

بررسی تعداد سلول‌های T تنظیمی در بیماران مبتلا به بیماری کرون

Background and purpose: Crohn disease (CD) is an autoimmune disorder in which a failure of tolerance to the intestinal antigens plays a pivotal role in the pathogenesis of this disease. Treg cells control immune responses to self and foreign antigens and have an important role in maintaining self-tolerance. In this study we evaluated the frequency of Tregs in the peripheral blood of patients wi...
