BACKGROUND Regulatory CD4+ T (Treg) cells are effective in maintaining immune tolerance. OBJECTIVE To investigate single nucleotide polymorphisms (SNPs) of Transforming Growth Factor β-1 (TGF-β1) and Forkhead Box Protein 3 (FOXP3) genes in Iranian patients with allergic rhinitis (AR). METHODS Variations at codons 10 and 25 of TGF-β1 and FOXP3 at(More)
BACKGROUND The therapeutic effect of herbal materials in inhibition of cancer cell growth was shown. This study investigates the effect of fig tree latex (Ficus carica) on stomach cancer line. METHODS The in vitro effect of different doses of fig tree latex on stomach cancer cell line and the peripheral blood mononuclear cells was evaluated after 72(More)
Multiple sclerosis (MS) is an autoimmune multifactorial degenerative disease with detrimental affliction on central nervous system. MHC class I chain- related geneA,B(MICA and MICB) are nonclassical human leukocyte antigens that can affect on some diseases and also on transplantation. The purpose of this study was to evaluate the MICA and MICB MRNA(More)
Variety of positive as well as negative regulatory signals are provided by antigen presenting cell in particular by dendritic cells. In this research, we studied the capacity of dendritic cells to expand antigen-specific T regulatory cells.We also investigated the role of TGF-beta in induction inhibitory functions of dendritic cells in mixed leukocyte(More)
Many recent studies have been conducted to evaluate protective immunity mediated by DNA vaccines against toxoplasmosis. Cocktail DNA vaccines showed better immune responses compared to single vaccines. The objective of the current study was to evaluate the protective efficacy of rhomboid 4 (ROM4) and cocktail DNA vaccines (ROM4 + GRA14) of the Toxoplasma(More)
Chronic hepatitis B virus (HBV) infection is a major liver disease worldwide and its clinical manifestations are linked to immune response. The purpose of this study was to evaluate the relationship between selenium, copper, and zinc in comparison with transaminase level in chronic HBV patients. Serum samples of the HBV infected patients were obtained from(More)
Leishmaniasis is a worldwide uncontrolled parasitic disease due to the lack of effective drug and vaccine. To speed up effective drug development, we need powerful methods to rapidly assess drug effectiveness against the intracellular form of Leishmania in high throughput assays. Reporter gene technology has proven to be an excellent tool for drug screening(More)
BACKGROUND Gastric cancer accounts 8% of the total cancer cases and 10% of total cancer deaths worldwide. The indoleamine N-acetyl-5-methoxytryptamine, better known as melatonin, is the principal hormone produced by the pineal gland. Recently, it has shown some anticancer role in some malignancies such as breast and colon cancer; also, some of its(More)
Regulatory T (Treg) cells are essential for maintenance of peripheral tolerance and prevention of autoimmune diseases in part by producing immunosuppressive cytokines. Recently, microRNAs (miRNAs) have also been involved in autoimmune disorders, not least for their crucial role in the regulation of Treg biology and function. We simultaneously investigated(More)
Tolerogenic dendritic cells (DCs) may be valuable in transplantation for silencing immune reaction. Macrophage colony-stimulating factor (M-CSF)/IL-4 induces differentiation of cord blood (CB) monocytes into DCs (M-DCs) with tolerogenic phenotype/function. We assessed whether factors produced by tolerogenic DCs could modulate hematopoiesis. TGF-beta1 added(More)
