Results of genetic association studies in UC are conflicting. We propose that the power of candidate gene studies will increase when disease heterogeneity is taken into account. Phenotype frequencies of molecularly defined HLA-DR alleles, polymorphisms in the tumour necrosis factor-alpha (TNF-alpha), lymphotoxin-alpha (LT-alpha), IL-1 receptor antagonist (IL-1Ra) and IL-1beta genes were determi...
BACKGOUND: The prevalence of rheumatoid arthritis (RA) and its specific autoantibodies varies in different populations. This variability depends on the genetic polymorphism immune response genes among which HLA system plays a major role. AIM: We conducted preliminary study distribution HLA-DRB1 HLA-DQB1 first field level alleles sample 100 Albanian patients with RA. METHODS: In this context, we...
Two hundred Japanese panels were serologically typed for human leukocyte antigen (HLA) - DR to assign 65 HLA-DR8 haplotypes, which were then subdivided into two genotypes, i.e., DRB1*0802 and DRB1*0803, by a polymerase chain reaction (PCR)--based, simple, and practical method. The panels possessing DR8 specificity were firstly subjected to PCR with a couple of primers specifically to amplify th...
BACKGROUND HLA-DRB1 0401 is associated with susceptibility, while HLA-DRB1 0402 is associated with resistance to developing rheumatoid arthritis (RA) and collagen-induced arthritis in humans and transgenic mice respectively. The influence of gut-joint axis has been suggested in RA, though not yet proven. METHODOLOGY/PRINCIPAL FINDINGS We have used HLA transgenic mice carrying arthritis suscep...
BACKGROUND Type 1 diabetes (T1D) is a multifactorial autoimmune disorder where interaction and integration of immune response genes along with environmental factors play a role in autoimmune destruction of the insulin producing Pancreatic Beta cells. METHODOLOGY/PRINCIPAL FINDINGS We have studied four single nucleotide polymorphisms (FokI site in Exon 2, BsmI and ApaI sites in Intron 8 and Ta...
AIM To explore whether predisposition to autoimmune gastritis (AIG) is found in human leukocyte antigen (HLA), cytokine or killer cell immunoglobulin-like receptor (KIR) gene variations. METHODS Twelve Finnish patients with autoimmune-type severe atrophy of the gastric corpus were included. The patients' serum was analyzed for pepsinogen I and Helicobacter pylori (H. pylori) antibodies. DNA w...
The HLA-DRB1 gene was reported to be associated with anticitrullinated protein/peptide autoantibody (ACPA) production in rheumatoid arthritis (RA) patients. A new classification of HLA-DRB1 alleles, reshaping the shared epitope (SE) hypothesis, was recently found relevant in terms of RA susceptibility and structural severity. We investigated the relevance of this new classification of HLA-DRB1 ...
The association of insulin-dependent diabetes mellitus (IDDM) with certain HLA alleles is well documented in pediatric patients. Whether a similar association is found in adult-on-set IDDM is not clear, although the disease occurs after the age of 20 in 50% of cases. HLA class II DRB1, DQA1, and DQB1 alleles were studied in 402 type I diabetics and 405 healthy controls (all Caucasian) using oli...
OBJECTIVE Variation in the major histocompatibility complex (MHC) on chromosome 6p21 is known to influence susceptibility to multiple sclerosis with the strongest effect originating from the HLA-DRB1 gene in the class II region. The possibility that other genes in the MHC independently influence susceptibility to multiple sclerosis has been suggested but remains unconfirmed. METHODS Using a c...
The MHC class II transactivator gene (CIITA) is an important transcription factor regulating gene required for HLA class II MHC-restricted antigen presentation. Association with HLA class II variation, particularly HLA-DRB1*1501, has been well-established for multiple sclerosis (MS). In addition, the -168A/G CIITA promoter variant (rs3087456) has been reported to be associated with MS. Thus, a ...
