Background: Childhood idiopathic nephrotic syndrome (INS) is one of the most common glomerular diseases, characterized by heavy proteinuria, hypoalbuminemia, dyslipidemia and generalized edema. Although some progresses were made regarding the pathogenesis of this disease, there are a lot of questions still left unanswered. Some of them involve the implications of several cytokines, including tumor necrosis factor alpha (TNF-alpha), in the development and clinical course of INS. Objective: Our objective was to analyze the role of two single nucleotide polymorphisms of TNF-alpha gene in the development of pediatric INS and their implication in the response to corticosteroid therapy...

Converging evidence suggests important implications of immuno-inflammatory pathway in the risk and progression of schizophrenia. Prenatal infection resulting in maternal immune activation and developmental neuroinflammation reportedly increases the risk of schizophrenia in the offspring by generating pro-inflammatory cytokines including IL-6. However, it is not known how prenatal infection can induce immuno-inflammatory responses despite the presence of immuno-inhibitory Human Leukocyte Antigen-G (HLA-G) molecules...

Background: Post-diarrheal hemolytic-uremic syndrome (D+HUS) following Shiga toxin-producing Escherichia coli (STEC) infection is a serious condition lacking specific treatment. Host immune dysregulation and genetic susceptibility to complement hyperactivation are implicated in non-STEC-related HUS. However, genetic susceptibility to D+HUS remains largely uncharacterized. Methods: Patients with culture-confirmed STEC diarrhea, identified through the CDC FoodNet surveillance system (2007-2012), were serotyped and classified by laboratory and/or clinical criteria as suspected, probable, or confirmed D+HUS, or as controls and genotyped at 200 loci linked to non-diarrheal HUS or similar pathologies...

The macrophage migration inhibitory factor (MIF) is a cytokine that plays an important role in inhibiting the growth of pathogenic Mycobacterium tuberculosis (M.tb) and regulates immune responses against M.tb pathogen. MIF -173 G > C gene polymorphism may affect immunity in an individual and leads to susceptibility to tuberculosis (TB). A large number of studies have investigated the relevance of this polymorphism with TB risk, but their results were inconclusive. To obtain a precise conclusion, a meta-analysis was performed by retrieving six eligible studies from Google Scholar, PubMed (Medline), and EMBASE online databases...

Vitiligo is a condition of the skin distinguished by hypo-pigmentation. Etiology of this disorder is unknown, and several theories and mechanisms have been hypothesized. The inflammatory response in vitiligo is thought to be mediated by polymorphism in genes such as FOXP3, ACE, APE, GSTP1, TLR, SOD, CTLA-4, TAP/LMP gene cluster, etc. Theories including reactive oxygen species model, Nrf2-antioxidant response element (ARE) pathway, WNT pathway, tyrosinase activity, biochemical, molecular, and cellular alterations have been hypothesized to explain vitiligo pathogenesis...

Overexpression of the proinflammatory cytokine macrophage migration inhibitory factor (MIF) is linked to a number of autoimmune diseases and cancer. MIF production has been correlated to the number of CATT repeats in a microsatellite region upstream of the MIF gene. We have characterized the interaction of pituitary-specific positive transcription factor 1 (Pit-1) with a portion of the MIF promoter region flanking a microsatellite polymorphism (-794 CATT5-8). Using fluorescence anisotropy, we quantified tight complex formation between Pit-1 and an oligonucleotide consisting of eight consecutive CATT repeats (8xCATT) with an apparent Kd of 35 nM...

Schistosoma haematobium is a human blood fluke causing a chronic infection called urogenital schistosomiasis. Squamous cell carcinoma of the urinary bladder (SCC) constitutes chronic sequelae of this infection, and S. haematobium infection is accounted as a risk factor for this type of cancer. This infection is considered a neglected tropical disease and is endemic in numerous countries in Africa and the Middle East. Schistosome eggs produce catechol-estrogens. These estrogenic molecules are metabolized to active quinones that induce modifications in DNA...

Moyamoya disease (MMD) is a rare cerebrovascular disease characterized by a progressive stenosis at the terminal portion of the internal carotid artery and an abnormal vascular network at the base of the brain. Although its etiology is still unknown, intrinsic immune reactions such as autoimmune response has been implicated in the pathogenesis of MMD. Recently, the RING finger protein 213 (RNF213) was found to be an important risk gene for MMD, and is predominantly expressed in blood cells and the spleen. Thus, we hypothesized that patients with MMD represent an intrinsic autoimmune status mediated by M2-polarized macrophages, which play an important role in tissue remodeling and angiogenesis...

Background: Despite recent decrease in the incidence of gastric cancer, it is still a common type of cancer in the north of Iran. Many evaluations have shown that polymorphisms of cytokine genes like that for interleukin 6 (IL-6), which play important roles in regulation of the immune response, can increase the risk of gastric cancer. This study examined the role of the IL-6-174 gene polymorphism in susceptibility in an Iranian population. Method: Genomic DNA was extracted from peripheral whole blood of 100 patients and 361 healthy controls...

PURPOSE: Chronic inflammation is a key component in the development and progression of colorectal cancer (CRC). A notable hallmark of the inflammation process is the release of pro-inflammatory cytokines by infiltrating cells of the immune system. Defects in dendritic cells (DCs) recruitment, maturation and cytokine release are a hallmark of the CRC strategy to escape immune surveillance.The purpose of our study was to evaluate the possible role of IL-12B polymorphism in the promoter region of the IL-12B gene (rs17860508) as a genetic factor contributing to the risk for CRC development...

Obesity comorbidities are closely associated with chronic low-grade adipose tissue inflammation. A number of SNPs associated with inflammation has been identified, underscoring the impact of genetic determinants on this process. Here, we screened SNPs in genes with pro-inflammatory (IL-1β, IL-6, STAT3 and JAK2), anti-inflammatory (IL-10 and SOCS3) and pro-resolving (ERV1/ChemR23) properties in 101 obese and 99 non-obese individuals. Among the SNPs analyzed, we identified that individuals carrying a C allele in the rs1878022 polymorphism of the ERV1/ChemR23 gene, which encodes for the receptor of the pro-resolving mediator RvE1, had increased ERV1/ChemR23 protein expression and reduced levels of the inflammatory cytokine IL-6 in adipose tissue...

Despite detailed human leukocyte antigen (HLA) matching and modern immunosuppressive therapy, severe graft-versus-host disease (GvHD) remains a major hurdle for successful allogeneic hematopoietic stem cell transplantation (HSCT). As the genetic diversity in GvHD complicates the systematic discovery of associated variants across populations, we studied 122 GvHD-associated single nucleotide polymorphisms (SNPs) in 492 HLA-matched sibling HSCT donor-recipient pairs from Finland and Spain. The association between these candidate SNPs and grade III-IV acute GvHD and extensive chronic GvHD was assessed...
