خلاصه: Abstract- Juvenile idiopathic arthritis (JIA) is a clinically heterogeneous cluster of complex diseases, in which both the genetic and environmental factors seem to play a role in the development of the disease. The current study aims to assess the association of programmed cell death 1 (PDCD1, also called PD-1) gene variants with JIA vulnerability in Iranian population. In this case-control association study, we investigated a group of 50 Iranian patients ... سال انتشار: 2017
 

Lack of Association between STAT4 Single Nucleotide Polymorphisms and Iranian Juvenile Rheumatoid Arthritis Patients

مولف: Saeed Aslani, Mahdi Mahmoudi, Arash Salmaninejad, Shiva Poursani, Vahid Ziaee & Nima Rezaei

خلاصه: Juvenile rheumatoid arthritis (JRA) is a common chronic systemic autoimmune disease in children. Single nucleotide polymorphisms (SNPs) of signal transducer and activator of transcription 4 (STAT4) gene are suspected to have associationwith the risk of autoimmune diseases. Previous investigations have indicated that the STAT4 rs7574865 T allele was significantly associated with rheumatoid arthritis. In this study, we aimed to evaluate the association of STAT4 SNPs with JRA in Iranian population. T allele of STAT4 rs7574865 SNPwas less ... سال انتشار: 2017
 

Association Study of MECP2 Gene Single Nucleotide Polymorphisms in Juvenile-Onset Systemic Lupus Erythematosus Patients from Iran

مولف: Mahdi Mahmoudi, Saeed Aslani, Elham Hamzeh, Vahid Ziaee, Shiva Poursani, Mohammad Hossein Nicknam & Nima Rezaei

خلاصه: Introduction: Juvenile-onset systemic lupus erythematosus (JSLE) is a multigenic autoimmune disorder. Polymorphisms of MECP2 gene have been reported to increase the risk of adult-onset SLE. In this study, we aimed to analyze if MECP2 gene polymorphisms could impress the proneness to JSLE in Iranian population. Material and Methods: Polymorphisms of MECP2 gene were genotyped in 50 Iranian JSLE patients and 426 matched healthy controls employing the real-time PCR allelic discrimination technique. Results: None of the alleles and ... سال انتشار: 2017
 

Association Study of CD226 and CD247 Genes Single Nucleotide Polymorphisms in Iranian Patients with Systemic Sclerosis

مولف: Fatemeh Abbasi1, Reza Mansouri1, Farhad Gharibdoost2, Saeed Aslani2, Shayan Mostafaei2, Hoda Kavosi2, Shiva Poursani2, Soheila Sobhani2, and Mahdi Mahmoudi2

خلاصه: CD247 and CD226 play important roles in signaling of lymphocytes. Single nucleotide polymorphisms (SNPs) of genes encoding CD247 and CD226 have been associated with the risk of several autoimmune disorders. This study aimed to evaluate the possible association between CD226 and CD247 genes SNPs and risk of systemic sclerosis (SSc) in Iranian population. Study participants were 455 SSc patients and 455 age, sex, and ethnic -matched healthy individuals. Genotyping of rs2056626 ... سال انتشار: 2017
 

Association of STAT4 gene single nucleotide polymorphisms with Iranian juvenile-onset systemic lupus erythematosus patients

مولف: Arash Salmaninejad1, 2, Mahdi Mahmoudi1, 3, Saeed Aslani1, 3, Shiva Poursani1, Vahid Ziaee4, 5, Nima Rezaei6, 7, 8

خلاصه: SUMMARY: Salmaninejad A, Mahmoudi M, Aslani S, Poursani S, Ziaee V, Rezaei N. Association of STAT4 gene single nucleotide polymorphisms with Iranian juvenile-onset systemic lupus erythematosus patients. Turk J Pediatr 2017; 59: 144-149. Juvenile-onset systemic lupus erythematosus (JSLE) is a complex autoimmune disease, characterized by multi-organ involvement. Single nucleotide polymorphisms (SNPs) of signal transducer and activator of transcription 4 (STAT4) gene have been reported to have relationship with the risk of ... سال انتشار: 2017
 

Analysis of killer cell immunoglobulin-like receptors (KIRs) and their HLA ligand genes polymorphisms in Iranian patients with systemic sclerosis

مولف: Mahdi Mahmoudi1 & Faranak Fallahian2 & Soheila Sobhani1 & Shima Ghoroghi1 & Ahmadreza Jamshidi1 & Shiva Poursani 1 & Masoumeh Dolati2 & Zahra Hosseinpour1 & Farhad Gharibdoost1

خلاصه: Abstract Genetic factors have a great role in the pathogenesis of autoimmune diseases by cooperating with environmental stimuli. Killer immunoglobulin-like receptors (KIRs) are cell surface proteins on NK cells whose association with major histocompatibility complex-I regulates their killing function. The aim of this study was to provide information on the possible association between KIR and human leukocyte antigen (HLA) genes with systemic sclerosis disease in Iranian population. A total of 279 systemic sclerosis patients and 451 healthy controls were ... سال انتشار: 2017
 

Gene Expression Profiling of Toll-Like Receptor 4 and 5 in Peripheral Blood Mononuclear Cells of Patients with Systemic Sclerosis

Authers: Simin Almasi, 2Saeed Aslani, 1Hadi Poormoghim, 2Ahmadreza Jamshidi, 2Shiva Poursani and 2Mahdi Mahmoudi

Abstract: The Toll-Like Receptor (TLR) family is appeared to be expressed in many cell types in the immune system and plays a role in the pathogenesis of various autoimmune diseases. The expression profile and role of TLRs in Systemic Sclerosis (SSc) have been partly explained. It is aimed through this investigation to evaluate the expression pattern of TLR 4 and 5 in Peripheral Blood Mononuclear Cells (PBMCs) from SSc patients. PBMCs were isolated from whole blood of ... سال انتشار: 2016

Abstract: Systemic lupus erythematosus (SLE) is a systemic autoimmune disease of unknown etiology with a complex pathogenesis involving multiple genetic and environmental contributions. Single-nucleotide polymorphisms (SNPs) in cytokine genes are associated with higher or lower cytokine activity, which can alter the susceptibility to certain diseases or their clinical outcomes. We investigated SNPs of the IL-1 family in Iranian SLE patients and normal individuals. We obtained blood samples from 207 SLE patients and 213 healthy controls. Cytokine genotyping was performed by polymerase ... سال انتشار: 2013
