[ 1 ] - Altered Suppressor Function of Regulatory T Cells in Type 1 Diabetes

Background: Type 1 diabetes (T1D) is a T cell mediated autoimmune disease targeting the insulin-producing β cells within pancreatic islets. Autoimmune diseases may develop as a consequence of altered balance between regulatory (Tregs) and autoreactive T cells. Objectives: To evaluate Treg cells frequency and suppressive function in the peripheral blood of newly diagnosed T1D patients in compari...

[ 2 ] - Anti-HLA Antibodies and Kidney Allograft Outcomes in Recipients with Donor Bone Marrow Cell Infusion

Background: Anti-HLA-antibodies are known to affect the allograft survival in transplant recipient patients. Objective: The aim of this study was to evaluate the association between anti-HLA antibodies and kidney allograft outcomes, particularly in recipients with concur-rent donor bone marrow cell infusion (DBMI). Methods: Between June 2006 and May 2007, forty living unrelated donor kidney tra...

[ 3 ] - HLA-DRB1, DQA1 and DQB1 Alleles and Hap-lotypes Frequencies in Iranian Healthy Adult Responders and Non-Responders to Recombi-nant Hepatitis B Vaccine

Background: Different studies have demonstrated that a small proportion of healthy individuals receiving the hepatitis B (HB) vaccine do not produce protective levels of anti-HB antibody, a phenomenon which could be linked to certain human leukocyte an-tigen (HLA) class-II alleles or haplotypes. Objectives: The present study was under-taken to determine the frequency of HLA class-II alleles in ...

[ 4 ] - A Five Years Study of Tuberculous Meningitis in Iran

Background: Tuberculous meningitis (TBM) is a severe form of extra pulmonary tuberculosis with high mortality and morbidity rate in all age group patients specific in adults and children. The incidence and prevalence are not exactly known in Iran. In this study, we tried to evaluate the role of rapid diagnosis and to find out the highest risk group patients.  Methods:Totally,...

[ 5 ] - بررسی ارتباط پلی‌مورفیسم‌ PD-1 با بیماری اسکلروز متعدد

Background: Multiple sclerosis (MS) is a chronic inflammatory demyelinating disease of the central nervous system with presumed autoimmune origin. T cells are considered to play a pivotal role in orchestrating the self-reactive immune responses in multiple sclerosis (MS). This study was performed to investigate the role of polymorphisms of the programmed cell death 1 (PD-1) gene on susceptibili...
