Recurrent pregnancy loss (RPL) is defined as three or more sequential abortions before the 20th week of gestation. There is increasing evidence to support an immunological mechanism for the occurrence of RPL. Defective production of T helper type 2 (Th2) and/or higher production of T helper type 1 (Th1) cytokines have been reported in RPL. As cytokine gene polymorphisms may be associated with d...
AIM Suppressor of Cytokine Signaling 3 (SOCS3) gene belongs to SOCS family as one of the negative regulators of cytokine signaling and IFN response that function via the JAK-STAT pathway in antiviral response. SOCS3 expression and genetic polymorphism influences the pathogenesis and outcome of antiviral treatment in hepatitis C virus (HCV) infected patients. This study was designed for analysis...
The cytokines IL-4, IL-13, and IL-5 are markers for the Th2 subset of effector T cells and are often expressed together. These cytokine genes are organized within 140 kb of orthologous DNA in both mouse and human. Using IL-4-expressing CD4+ T cell clones derived from F1 mice, we identified allelic polymorphisms for each of these cytokines and assessed the parental identity of the cytokine mRNAs...
Introduction: Visceral leishmaniasis (VL) or Kala-azar is a parasitic disease caused by a protozoan of Leishmania genus and in Iran by Leishmania infantum. Cytokines have a major role in determining progression and severity of clinical manifestations in VL. The role of TGF-β1 in VL has been recognized since 1992. We investigated polymorphism in the TGF-β1 gene, which is a cytokine known to have...
NASH consists in lipid accumulation in hepatocytes that trigger oxidative stress, secretion of proinflammatory cytokines leading to steatohepatitis (NASH). The study aimed to investigate the levels of proinflammatory (TNF-α and IL-6) along with anti-inflammatory cytokine IL-10 in patients with NASH and to correlate the cytokines' level with their polymorphism. Sixty-six patients with NASH and 3...
The emergence of syncytium-inducing (SI) variants of human immunodeficiency virus type 1 (HIV-1) in infected individuals is an indicator of poor prognosis and is often correlated with faster CD4(+) cell depletion and rapid disease progression. Interleukin-4 (IL-4) is a pleiotropic cytokine with various immune-modulating functions including induction of immunoglobulin E (IgE) production in B cel...
Hypersensitivity pneumonitis (HP) is an immunologically-mediated lung disease caused by repeated inhalation of dispersed antigen. Various cytokines have been reported to be involved in the immunopathogenesis of HP Recently, some reports suggested an association between the genetic control of cytokine production and disease susceptibility. To evaluate whether cytokine gene polymorphisms are asso...
Certain cytokine gene polymorphisms have been shown to correlate with outcome of human leukocyte antigen (HLA) identical sibling donor stem cell transplantation (SCT), but in unrelated donor SCT such information is scarce. We have studied the association between cytokine gene polymorphism and transplant-related mortality (TRM) in 182 unrelated SCTs performed at a single center. We found associa...
BACKGROUND Cytotoxic T lymphocyte associated antigen 4 (CTLA-4) has been one ofthe non HLA genes more commonly studied in type 1 diabetes mellitus (TID). CTLA-4 is a co-stimulation protein that has a key role in the negative regulation ofT cells and is related with a functional cytokine imbalance, generating a T helper (Th) 1 over Th2 dominance. AIM To analyze the association of +49 A/G polym...
BACKGROUND Obesity development is a complex process which can be influenced by genetic predisposition modified by environmental factors. Nowadays, the problem of overweight and obesity, including related complications, occurs in increasingly younger children. Thus, there is a need for new genetic markers of increased risk of excessive body mass. OBJECTIVE The aim of the present study was to e...
