خلاصه: Macrophages play an important role in the ankylosing spondylitis (AS) auto-inflammatory responses and fibrocartilage destruction. Adenosine is a key modulator of inflammatory conditions. The various effects of adenosine are mediated by its interaction with adenosine receptors (AR). In this study, we investigated the mRNA expression ofA1, A2A, A2B, andA3 adenosine receptors, ectonucleoside triphosphate diphosphohydrolase-1 (CD39), and ecto-5′-nucleotidase (CD73) in the monocyte-derived macrophages from AS patients in comparison to healthy controls. We also explored the ... سال انتشار: 2018

Epigenetic involvement in etiopathogenesis and implications in treatment of systemic lupus erythematous

مولف: Arron Munggela Foma1 • Saeed Aslani1, 2 • Jafar Karami2, 3 • Ahmadreza Jamshidi2 • Mahdi Mahmoudi

خلاصه: Abstract Background Recent researches in the field of genetics have extended our knowledge through the discovery of genetic factors associated with autoimmune diseases (AID). Genetics by itself, however, cannot elucidate all the uncertainties encountered in the etiopathology of AID. On the other hand, incomplete harmony in the prevalence of AID in identical twins suggests that non-genetic factors may play an important role in determining the disease susceptibility. Besides, epigenetics, which is defined by changes in gene expression without a corresponding change ... سال انتشار: 2017

Inhibition of MicroRNA-21 induces apoptosis in dermal fibroblasts of patients with systemic sclerosis

Authers: Saeideh Jafarinejad-Farsangi1, PhD, Ali Farazmand1, PhD, Farhad Gharibdoost2, MD, Elham Karimizadeh1, PhD, Farshid Noorbakhsh3, PhD, Habibeh Faridani2, MD, Mahdi Mahmoudi2, PhD, and Ahmad Reza Jamshidi2, MD

Abstract: Prolonged activation of dermal fibroblasts is the main cause of progressive fibrosis in systemic sclerosis (SSc). It seems that inhibition of apoptosis in SSc fibroblasts deregulates fibrosis. MicroRNA-21 (miR-21) is a pro-fibrotic factor with high expression in lesional areas of SSc skin and fibroblasts. Methods The effects of miR-21 on expression of Bcl-2 and Bax, two apoptotic genes, in dermal fibroblasts of SSc patients were evaluated using real-time polymerase chain reaction and Western blot analysis. Apoptotic ... سال انتشار: 2016

Determination of IL1 R2, ANTXR2, CARD9, and SNAPC4 single nucleotide polymorphisms in Iranian patients with ankylosing spondylitis

Abstract: Ankylosing spondylitis (AS) is a chronic inflammatory disease of unknown origin, while both genetic and environmental factors have been demonstrated to be etiologically involved. Recent genome-wide association and replication studies have suggested that anthrax toxin receptor 2 (ANTXR2), interleukin-1 receptor 2 (IL1R2), caspase recruitment domain-containing protein 9 (CARD9), and small nuclear RNA-activating complex polypeptide 4 (SNAPC4) seem to be associated with AS pathogenesis. This case–control study was performed on 349 unrelated AS patients and 469 age- and gender-matched healthy controls, ... سال انتشار: 2016

A Multidisciplinary Work-Related Low Back Pain Predictor Questionnaire: Psychometric Evaluation of Iranian Patient-Care Workers

Abstract: Study Design: Psychometric evaluation design. Purpose: Psychometric evaluation of a multidisciplinary work-related low back pain predictor questionnaire (MWRLBPPQ) of Iranians patient-care workers based on the social cognitive theory. Overview of Literature: Healthcare is one of the professions in which work-related musculoskeletal disorders are prevalent. The chronic low back pain experienced by patient caregivers can negatively impact their professional performance, and patient handling in a hospital is the main cause of low back ... سال انتشار: 2016

c-Abl silencing reduced the inhibitory effects of TGF-b1 on apoptosis in systemic sclerosis dermal fibroblasts

مولف: Elham Karimizadeh1 • Farhad Gharibdoost2 • Nasrin Motamed1 • Saeideh Jafarinejad-Farsangi1 • Ahmadreza Jamshidi2 • Mahdi Mahmoudi

خلاصه: It is generally accepted that the apoptosis of myofibroblasts is a crucial event in the normal wound healing. Delay in myofibroblasts apoptosis results in fibrotic diseases such as systemic sclerosis (SSc). Transforming growth factor-b1 (TGF-b1) is an important cytokine to induce fibroblasts differentiation into myofibroblasts. Cellular Abelson (c-Abl) is known as a TGF-b1- modulating molecule in fibrosis. The role of c-Abl, TGFb1, and their interaction in SSc myofibroblasts apoptosis has not yet been fully explored. The aim of this ... سال انتشار: 2015
