[ 1 ] - CD4+ T Cells are Exhausted and Show Functional Defects in Chronic Lymphocytic Leukemia
Background: Chronic lymphocytic leukemia (CLL) is the most common adult leukemia in the western world. This health problem is caused due to the accumulation of mature B-lymphocytes in the peripheral blood and bone marrow. In the course of cancer, CD4+ T cells become “exhausted” and characterized with poor effector functions and the expression of multiple inhibitory receptors. Objective: To inve...
[ 2 ] - Regulatory T Cells and Myeloid-Derived Suppressor Cells in Patients with Peptic Ulcer and Gastric Cancer
Background: Regulatory T Cells (Tregs) and Myeloid-Derived Suppressor Cells (MDSCs) are two main regulatory cells modulating the immune responses in inflammation and cancer. Objective: To investigate and compare Tregs and MDSCs in peptic ulcer and gastric cancer. Methods: Patients with dyspepsia were selected and divided into three groups of non-ulcer dyspepsia (NUD, n=22), peptic ulcer disease...
[ 3 ] - Increased Expression of Two Alternative Spliced Variants of CD1d Molecule in Human Gastric Cancer
Background: CD1d presents glycolipid antigens to invariant natural killer T (iNKT) cells. The role of CD1d in the development of peptic ulcer and gastric cancer has not been revealed, yet. Objective: To clarify the expression of alternatively spliced variants of CD1d in peptic ulcer and gastric cancer. Methods: Patients with dyspepsia were selected and divided into three groups of non-ulcer dys...
[ 4 ] - Aqueous Humor and Serum Concentrations of Soluble MICA and MICB in Glaucoma Patients
Background: Immune reactions have been reported to be involved in the destruction of retinal ganglion cells (RGCs) in glaucoma. Objective: To investigate the role of major histocompatibility complex class I-related chain A and B (MICA and MICB) molecules in the pathogenesis of glaucoma. Methods: Aqueous humor and serum samples from 15 glaucoma patients and 45 patients with cataract, undergoing ...
[ 5 ] - Toll Like Receptor-4 896A/G Gene Variation, a Risk Factor for Migraine Headaches
Background: The pathogenesis of migraine involves immune-mediated mechanisms in the vascular endothelium. Toll like receptor 4 (TLR-4) is a signaling receptor of innate immunity which plays a role in various neuropathologies related to neuron inflammation. Objective: This case/control study is aimed to investigate whether TLR- 4 896A/G variation is related to migraine headaches in an Iranian po...
[ 6 ] - بررسی فتوتیپهای سلولیNatural killer (NK) و سلولهای شبه Natural killer T(NKT) در بیماران مبتلا به زخم پپتیک و سرطان معدهی ناشی از عفونت هلیکوباکتر پیلوری
Background and purpose: The aim of this study was to compare the proportion of natural killer (NK) and natural killer T (NKT)-like cells in dyspeptic disorders caused by Helicobacter pylori (H. pylori). Materials and methods: In a case-control study, 27 patients with gastric cancer (GC), 25 patients with peptic ulcer (PUD), and 22 patients with non-ulcer dyspepsia (NUD) were enrolled. After en...
[ 7 ] - Blimp-1 Expression as an Exhaustion Transcription Factor in Chronic Lymphocytic Leukemia
Background: PPreviously, it was shown that exhausted CD4+ and CD8+ T cells in chronic lymphocytic leukemia (CLL) co-express the two immune-inhibitory receptors, Tim-3 and PD-1. Present study investigated the expression of Blimp-1, a transcription factor involved in T cell exhaustion, in patients with CLL. Materials and Methods: Peripheral blood mononuclear cells were collected from 25 untreate...
[ 8 ] - Generation of CHO Stable Cell Line Overexpressing HER2: an In Vitro Model for Breast Cancer
Background: Breast cancer is the most common female malignancy and the leading cause of cancer mortality in women worldwide. The human epidermal growth factor receptor2 (HER2) is a transmembrane tyrosine kinase receptor that is usually overexpressed in human breast cancers. Stable cell lines heterogeneously overexpressing HER2 are highly required as in vitro models for breast cancer research. T...
