BACKGROUND Single-nucleotide polymorphisms (SNPs) in immune genes have been associated with susceptibility to invasive mold infection (IMI) among hematopoietic stem cell but not solid-organ transplant (SOT) recipients. METHODS Twenty-four SNPs from systematically selected genes were genotyped among 1101 SOT recipients (715 kidney transplant recipients, 190 liver transplant recipients, 102 lun...
BACKGROUND There is growing evidence of the importance of genetic predisposition and the activation of the mucosal immune system in the pathogenesis of inflammatory bowel disease. Thus, genes involved in the regulation of inflammation are receiving increased attention. We have studied whether Crohn's disease (CD) or ulcerative colitis (UC) is associated with certain allelic combinations of IL1B...
Background: Interleukin (IL)1a and IL1b, and their endogenous receptor antagonist (IL1Ra), have been related to the pathology of systemic lupus erythematosus (SLE), but the role of IL1 polymorphisms in the aetiology of SLE is unknown. Objective: To examine polymorphisms at IL1a 2889(CRT), IL1a +4845(CRT), IL1b 2511(CRT), IL1b +3953(GRT), and IL1Ra (86 bp VNTR) in a population based study of SLE...
BACKGROUND Cytokines are suggested to play a role in periodontitis. OBJECTIVES To determine and compare the levels of Interleukin-1 beta (IL-1β) and Tumor necrosis factor alpha (TNF-α) in gingival crevicular fluid (GCF) samples amongst healthy individuals and those with chronic periodontitis. Further to compare the GCF cytokine levels in three genotype classes defined by the respective gene p...
Single-nucleotide polymorphisms (SNPs) in cytokine genes can affect gene expression and thereby modulate inflammation and carcinogenesis. However, the data on the association between SNPs in the interleukin 1 beta gene (IL1B) and colorectal cancer (CRC) are conflicting. We found an association between a 4-SNP haplotype block of the IL1B (-3737C/-1464G/-511T/-31C) and CRC risk, and this associat...
BACKGROUND There is increasing evidence that the cytokine network is central to the immunopathology of inflammatory airway diseases. The interleukin 1 (IL-1) receptor antagonist (IL-1RN) is a naturally occurring anti-inflammatory agent that binds to the IL-1 receptor but does not possess agonist activity. Each of the genes of the IL-1 locus on chromosome 2q14 is polymorphic. The IL1RN gene cont...
OBJECTIVE To replicate and extend recent findings in a Turkish population of associations between chronic rhinosinusitis (CRS) with nasal polyposis and single-nucleotide polymorphisms (SNPs) in the IL1A (rs17561 and Ser114Ala), IL1B (rs16944), and TNF (rs361525 and rs1800629) genes. DESIGN In a case-control replication study, DNA samples were obtained from 206 patients with severe CRS (cases)...
OBJECTIVE It has been suggested that polymorphisms in IL1 are correlated with severe and/or erosive rheumatoid arthritis (RA), but the implicated alleles have differed among studies. The aim of this study was to perform a broad and well-powered search for association between allelic polymorphism in IL1A and IL1B and the susceptibility to or severity of RA. METHODS Key coding and regulatory re...
BACKGROUND Interleukin-1B (IL-1B) is a key pro-inflammatory cytokine that has been associated with the development of atherosclerosis and myocardial infarction. However, the prospective associations between functional single nucleotide polymorphisms (SNPs) in IL1B and incident acute coronary syndrome (ACS) have not been thoroughly investigated. The aims of this study were to examine the associa...
PURPOSE To investigate the genetic association between unrelated Korean keratoconus patients and interleukin 1 alpha (IL1A), interleukin 1 beta (IL1B), and IL1 receptor antagonist (IL1RN) gene polymorphisms. METHODS We investigated the association between IL1A (rs1800587, rs2071376, and rs17561), IL1B (rs1143627, rs16944, rs1143634, and rs1143633), and IL1RN (rs419598, rs423904, rs424078, and...
