Differential association of polymorphisms in the TNFalpha region with psoriatic arthritis but not psoriasis.

2002

To investigate the potential association of tumour necrosis factor alpha (TNFalpha) microsatellite and promoter alleles with psoriatic arthritis (PsA).DNA from 89 white patients with PsA, 65 patients with psoriasis, and 99 healthy white controls was investigated for two TNFalpha promoter (-238 and -308) and three microsatellite polymorphisms (TNFa, c, and d). Patients had previously been studied by serology for HLA class I antigens and by sequence-specific polymerase chain reaction for DRB1* alleles. In addition, TNFalpha production of Ficoll separated peripheral blood mononuclear cells (PBMC) into culture supernatants after stimulation with lipopolysaccharide, alphaCD3 antibodies, phytohae…

IL 10.G microsatellites mark promoter haplotypes associated with protection against the development of reactive arthritis in Finnish patients.

2001

Objective To investigate the association of microsatellites and single-nucleotide promoter polymorphisms (SNPs) in the gene for the cytokine interleukin-10 (IL-10) with susceptibility to and outcome of reactive arthritis (ReA). Methods From genomic DNA, IL-10 microsatellites G and R and IL-10 promoter polymorphisms at positions −1087 and −524 were typed by polymerase chain reaction, automated fragment length analysis, and restriction fragment digestion in 85 Finnish patients with ReA and 62 HLA–B27–positive Finnish controls. ReA patients had been followed up for 20 years. Genotypes and haplotypes of IL-10 were correlated with distinct features of the disease course, such as triggering agent…

Different Transcriptional Activity and In Vitro TNF-α Production in Psoriasis Patients Carrying the TNF-α 238A Promoter Polymorphism

2000

Genes encoded on chromosome 6 within the major histocompatibility complex region are thought to play an important role in the pathogenesis of psoriasis. A potential candidate gene is tumor necrosis factor alpha. The tumor necrosis factor alpha promoter contains several polymorphisms including two G--A transitions at position -308 and -238, which are the most common in Caucasian populations. The TNF238.2 (-238A) allele has been strongly associated with psoriasis. We have investigated the effect of the -238 and -308 variants on transcription of the tumor necrosis factor alpha gene in luciferase reporter gene assays. In addition, peripheral blood mononuclear cells of 47 patients with psoriasis…

Interleukin 10 polymorphisms in ankylosing spondylitis.

2003

Genetic polymorphisms of the IL10 promoter region have been implicated in many autoimmune diseases, including seronegative spondyloarthropathies. We studied three SNPs (IL10-1087, -824, and -597) and two microsatellites (IL10R and IL10G) lying within the promoter region of IL10 for association with susceptibility to and clinical manifestations of ankylosing spondylitis (AS), a common form of spondyloarthritis. Four hundred and sixty-eight individuals from 182 Finnish families affected with AS were studied. No association between individual IL10 promoter region polymorphisms or marker haplotype was observed with susceptibility to AS, but weak association was noted between the IL10-597 and -8…
