[ 6 ] - IL-17 and IL-4 Producing CD8+ T Cells in Tumor Draining Lymph Nodes of Breast Cancer Patients: Positive Association with Tumor Progression
Background: CD8+ cytotoxic T lymphocytes have been recently divided based on their cytokine expression profile. Objective: To evaluate the percentages of CD8+ lymphocytes and their effector subsets including Tc1, Tc2 and Tc17 in the tumor draining lymph nodes (TDLNs) of patients with breast cancer. Methods: Single cell suspensions were obtained from TDLNs of 42 patients with breast cancer. Stai...
[ 7 ] - Effect of Thermal Stress on MICA/B Induction in a Human Liposarcoma Cell Line
Background: A possible mechanism by which hyperthermia enhances tumor immunogenicity is the induction of NKG2D ligands on tumor cells. Although the expression of MHC class I chain-related protein A and B (MICA/B) has previously been reported in different carcinomas, there is no information about MICA/B expression in liposarcomas. Objective: To investigate MICA/B induction in a human liposarcoma...
[ 8 ] - CCL22 16C/A Genetic Variation is not Associated with Breast Carcinoma in Southern Iranian Population
Background: CCL22/MDC is a CC chemokine with a critical role in regulation of the immune balance in physiological condition. CCL22/CCR-4 ligation has been documented to participate in the migration of regulatory T (Treg) cells and Th2 lymphocytes to the site of breast tumors; circumstances that are known to be associated with poor prognosis. Objective: To investigate the association of a single...
[ 9 ] - Evaluation of the Immunomodulatory Effect of Curdlan on Maturation and Function of Mouse Spleen-Derived Dendritic Cells
Background: T helper 1 and T helper 17 cells play important roles in immunity against foreign invaders. Differentiation of these Th subsets is affected by state of maturation and cytokines that are produced by dendritic cells (DCs). Curdlan is a linear (1→3)-β- glucan and has shown activity against tumors and infectious agents. Objective: This study aims to investigate whether curdlan plays its...
[ 10 ] - Strong Association of CTLA-4 Variation (CT60A/G) and CTLA-4 Haplotypes with Predisposition of Iranians to Head and Neck Cancer
Background: Variations in Cytotoxic T Lymphocyte Antigen-4 (CTLA-4) affect the expression and function of this protein. Objective: We aimed to investigate the association of +49 A/G (rs231775), +1822 C/T (rs231779) and +6230 A/G (CT60, rs3087243) genetic variations, as well as the merged haplotypes in CTLA-4 gene with susceptibility to, or progression of head and neck cancer. Methods: Eighty pa...
[ 11 ] - Stromal Cell Derived Factor-1 Genetic Variation at Locus 801 in Patients with Myasthenia Gravis
Background: Myasthenia gravis (MG) is the most common disorder of neuromuscular junction in which autoantibodies develop against nicotinic acetylcholine receptor for unknown reasons.

Objective: The aim of this study was to investigate correlation between a genetic variation in Stromal Ce...
[ 12 ] - بررسی میزان بیان ژن E- cadherin در خون محیطی بیماران مبتلا به سرطان پستان در منطقه جنوب ایران
زمینه: سرطان پستان شایعترین بدخیمی در زنان است و به عنوان دومین عامل مرگ ومیر ناشی از سرطانها محسوب میشود. مولکول E- cadherin، یک مولکول گلیکوپروتئینی است که از عرض غشا عبور کرده و در اتصال سلول به سلول نقش اساسی را ایفا میکند. با توجه به نقش مولکول اشاره شده، به نظر میرسد که میزان بیان این مولکول میتواند در سرکوب تومور و جلوگیری از متاستاز تومور به دیگر قسمتهای بدن نقش اساسی را ایفا نما...
