Dual Role of but Not Inflammasome Polymorphisms in Type 1 Diabetes and Celiac Disease in Children.

Genetic polymorphisms in genes coding for inflammasome components and have been associated with autoinflammatory and autoimmune diseases. On the other hand several studies suggested that NLRP3 inflammasome contributes to maintenance of gastrointestinal immune homeostasis and that activation of NLRP3 is regulated by protein tyrosine phosphatase non-receptor 22 (PTPN22). polymorphism was implicated in the risk for various autoimmune diseases including type 1 diabetes (T1D) but not for celiac disease (CD).

When type 1 diabetes meets celiac disease.

Type1 diabetes (T1D) and celiac disease (CD) may occur together. HLA-DQ8 and DQ2 are key genetic risk factors in both. Overall, the patients with co-existing T1D and CD (T1D+CD) were shown to have HLA profile more similar to patients with T1D than those with CD.

Full-length extension of HLA allele sequences by HLA allele-specific hemizygous Sanger sequencing (SSBT).

The gold standard for typing at the allele level of the highly polymorphic Human Leucocyte Antigen (HLA) gene system is sequence based typing. Since sequencing strategies have mainly focused on identification of the peptide binding groove, full-length sequence information is lacking for >90% of the HLA alleles. One of the goals of the 17th IHIWS workshop is to establish full-length sequences for as many HLA alleles as possible.

High-risk genotypes HLA-DR3-DQ2/DR3-DQ2 and DR3-DQ2/DR4-DQ8 in co-occurrence of type 1 diabetes and celiac disease.

Shared susceptibility alleles in the HLA region contribute to the co-existence of type 1 diabetes (T1D) and celiac disease (CD). The aim of our study was to identify HLA genotype variations that influence co-occurrence of T1D and CD (T1D + CD) and the order of their onset. Totally 244 patients, 67 with T1D, 68 with CD and 69 with T1D + CD, (split into "T1D first" and "CD first"), were analyzed.

HLA-associated hemorrhagic fever with renal syndrome disease progression in slovenian patients.

Major histocompatibility complex (MHC) class I and class II genes regulate the balance between appropriate aggressive responses and invading pathogens while minimizing the destruction of host tissue. Several studies have shown that in hemorrhagic fever with renal syndrome (HFRS) patients, the disease outcome is determined by a complex interaction between the virus and immunopathologic and human genetic factors. In Slovenia, the severity of the disease caused by Puumala virus (PUUV) is significantly lower than that of HFRS due to Dobrava virus (DOBV).

Basiliximab versus daclizumab combined with triple immunosuppression in deceased donor renal transplantation: a prospective, randomized study.

Background: In this prospective, randomized, open-label, single-center study, we compared the efficacy and safety of two anti-interleukin-2 receptor monoclonal antibodies combined with triple immunosuppression.

Methods: The adult recipients of at least one human leukocyte antigen-mismatched deceased donor renal graft on cyclosporine microemulsion, mycophenolate mofetil, and methylprednisolone were randomized to induction with basiliximab or daclizumab, given in standard doses. An intent-to-treat analysis of 1-year data assessed the incidence of acute rejections, graft function, patient and graft survival, and safety of this therapy.

HLA class II polymorphism in autochthonous population of Gorski kotar, Croatia.

The aim of this study was to examine frequencies and haplotypic associations of HLA class II alleles in autochthonous population of Gorski kotar (Croatia). HLA-DRB1, -DQA1 and -DQB1 alleles were determined by DNA based PCR typing in 63 unrelated inhabitants from Gorski kotar whose parents and ancestors were born and lived in tested area for at least over four generations. A total of 13 HLA-DRB1, 12 DQA1 and 14 DQB1 alleles were identified.

Introduction to statistical analysis of population data in immunogenetics.

We review the most classical questions addressed by the analysis of population data in immunogenetics. Basic genetics' definitions are reminded. Questions related to the population data itself (structure, missing values nomenclature, sampling) are developed first, and secondly, the population genetics questions (relevance of genetic parameters (phenotype, genotype allele and haplotype frequencies; genetic distances; linkage disequilibrium measures), methods and practical computing) are illustrated by immunogenetics polymorphisms.

The contribution of HLA-Class II antigens in humoral non-response and delayed response to HBsAg vaccination.

The variability in the immune response modulated by HLA alleles may be an important factor for the induction of the protective effect of HBsAg vaccines. We present here the analysis of HLA-DRB1, DQB1 and DQA1 alleles and their combinations in the group of 36 individuals with poor humoral immmune response to HBsAg vaccination. Comparison with the control group, consisted of 60 randomly choosen healthy subjects, revealed that the DRB1*1601, DQB1*0502, DQA1*0102 haplotype is overrepresented in the group of hyporesponders and may therefore be regarded as a factor influencing poor antibody responsiveness.
