Recent randomized trials have not found that polymyxin B hemoperfusion (PMX-HP) improves outcomes for patients with sepsis. However, it remains unclear whether the therapy could provide benefit for highly selected patients. Monocyte human leukocyte antigen (mHLA-DR) expression, a critical step in the immune response, is decreased during sepsis and leads to worsening sepsis outcomes. One recent study found that PMX-HP increased mHLA-DR expression while another found that the treatment removed HLA-DR-positive cells. We conducted a randomized controlled trial in patients with blood endotoxin activity assay (EAA) level ≥ 0.6. Patients in the PMX-HP group received a 2-h PMX-HP treatment plus standard treatment for 2 consecutive days. Patients in the non-PMX-HP group received only standard treatment. The primary outcome compared the groups on median change in mHLA-DR expression between day 3 and baseline. Secondary outcomes compared the groups on the mean or median change in CD11b expression, neutrophil

Human leukocyte antigen genes associated with rheumatoid arthritis are commonly found in the unaffected population, implying that causal mechanisms of disease involve interactions between these genes and other factors. A variety of approaches-genetic, structural, and immunologic-are used to explore possible molecular interactions that may contribute to understanding the basis for this disease association. The specific relation between human leukocyte antigen-DR4 alleles and rheumatoid arthritis remains one of the strongest and most thoroughly studied examples of human leukocyte antigen risk genes among human autoimmune disorders.

T-cell and B-cell responses to genetic immunization differ in DR3 and DR2 transgenic mice, and there is less genetic control of antibody than of T-cell responses. During both genomic and peptide epitope immunization there was evidence of epitope spreading during the immunization. Several functionall …

Predicting patient outcome for colorectal carcinoma (CRC) with lymph node but not distant metastases remains challenging. Various prognostic markers have been identified including microsatellite instability (MSI) and possibly expression of the MHC Class II protein, HLA-DR. About 15% of sporadic CRC exhibits MSI associated with methylation of the DNA mismatch repair gene hMLH1 promoter. In addition, a significant proportion of unselected CRC demonstrates expression of HLA-DR. We sought to examine the relationship between HLA-DR expression, MSI status and prognosis in sporadic Australian Clinicopathological (ACP) Stage C CRC. Two hundred seventy consecutive patients with sporadic ACP Stage C CRC were treated at Concord Repatriation General Hospital between 1986 and 1992. None of these patients received adjuvant chemotherapy and all were followed for a minimum of 5 years or until death. DNA was extracted from paraffin sections and MSI status determined by PCR. HLA-DR expression was determined ...

Background: Pediatric bronchial asthma is associated with considerable morbidity. The study was carried out to examine the association of Human Leukocyte Antigen (HLA)- Class II with the disease as we found no similar study on Asian Indian population. Objective: To define the HLA-Class II antigens in Asian Indian pediatric patients with asthma. Methods: A total of 103 children with asthma and 152 controls were analysed for HLA Class II (DRB1, DQB1and DPB1) by PCR-SSP (Sequence Specific Primers) method. Total serum IgE levels were determined by ELISA assay. Results: A positive family history was recorded in 59 patients (57%) and 13 (8.5%) of healthy controls. Serum IgE levels were more than normal range in 72% of the patients and 33% of healthy subjects with mean values of 4877 and 627 IU/ml, respectively. DRB1*04 and DQB1*03 showed significant positive relations while DRB1*15 showed a negative association with asthma. DQB1*02 was more common in healthy individuals but was not statistically significant.

HLA-DR3 is composed of the HLA-DR17 and HLA-DR18 split antigens serotypes. DR3 is a component gene-allele of the AH8.1 haplotype in Northern and Western Europeans. Genes between B8 and DR3 on this haplotype are frequently associated with autoimmune disease. Type 1 diabetes mellitus is strongly associated with HLA-DR3 or HLA-DR4. Some DR3 also react with HLA-DR17 and/or HLA-DR18. The DRB1*0304 primarily reacts with DR3. The serotypes of *0305, *0306, *0308 to *0331 are unknown. HLA-DR3 is associated with early-age onset myasthenia gravis, Hashimotos thyroiditis (along with DR5), primary sclerosing cholangitis, and opportunistic infections in AIDS, but lowered risk for cancers. It is also associated with Membranous glomerularnephritis DRB1*0301 (see HLA-DR17) DRB1*0302 (See HLA-DR18) DRB1*0304 is associated with graves disease DR3 and/or DQ2 is associated with Moreens ulceration, bout onset multiple sclerosis, Graves disease and systemic lupus erythematosus DR3-DQ2 linkage is associated ...

HLA-DR is an MHC class II cell surface receptor encoded by the human leukocyte antigen complex on chromosome 6 region 6p21.31. The complex of HLA-DR (Human Leukocyte Antigen - antigen D Related) and its ligand, a peptide of 9 amino acids in length or longer, constitutes a ligand for the T-cell receptor (TCR). HLA (human leukocyte antigens) were originally defined as cell surface antigens that mediate graft-versus-host disease. Identification of these antigens has led to greater success and longevity in organ transplant. Antigens most responsible for graft loss are HLA-DR (first six months), HLA-B (first two years), and HLA-A (long-term survival). Good matching of these antigens between host and donor are most critical for achieving graft survival. HLA-DR is also involved in several autoimmune conditions, disease susceptibility and disease resistance. It is also closely linked to HLA-DQ and this linkage often makes it difficult to resolve the more causative factor in disease. HLA-DR molecules are ...

The T cell response to a mixture of eight peptides derived from sequences of the Mycobacterium tuberculosis 16-, 19- and 38-kD antigens (MTBmix-8) has been studied.

FGF-2 and, to a lesser extent, PDGF-BB induced in adult human MSCs the expression of HLA-DR (normally induced by inflammatory cytokines), which was able to stimulate CD4+ T cells via superantigen binding. In contrast to IFNγ, FGF induced HLA-DR expression only in human MSCs proliferating under its mitogenic effect and not in mouse MSCs or in differentiated human cells. Although it induced cell proliferation, human platelet lysate did not cause HLA-DR expression in human MSCs. HLA-DR expression occurred following FGF-specific binding to its receptor(s), mainly FGF receptor 1, without inducing IFNγ or tumor necrosis factor α expression. Both MAPK/ERK-1/2 and phosphatidylinositol 3-kinase/Akt controlled cell proliferation and HLA-DR expression, but only MAPK/ERK-1/2 controlled the induction of the class II MHC transcription activator protein CIITA, the major determinant of HLA-DR transcription. ...

Vaccination of colon cancer patients with X-irradiated autologous tumor cells and Bacillus Calmette-Guérin results in a significant reduction in tumor recurrence. A study was undertaken to determine whether the expression of tumor-associated antigens, expression of major histocompatibility complex molecules, or the cellular composition of the vaccine cells correlates with vaccine efficacy. A significant increase in the percentage of histocompatibility leukocyte antigen (HLA) class II molecule-expressing tumor cells was the only marker with a positive correlation. Because HLA class II molecule expression is not a prognostic marker in control patients, it was hypothesized that HLA class II molecules are involved in the induction of tumor immunity in patients treated with the autologous colon tumor vaccine. Enhancement of HLA class II molecule-expressing cells could be induced in X-irradiated colon tumor cells injected into the skin of mice when the cells were mixed with γ-interferon. Therefore, ...

Cellular immunity plays an important role in the control of persistent virus infections such as hepatitis C virus (HCV). Antiviral CD4(+) T cell responses have been shown to accompany resolution of acute disease and there is also a consistent association between HLA Class II genes, notably HLADRB1*1101 (and the closely linked HLADQB1*0301) and disease resolution. We initially mapped longitudinal CD4(+) T cell responses in an individual after spontaneous resolution of acute HCV, and identified three HLA-DR11-restricted responses which vary in immunodominance over time. Functional assays and HLA Class II tetramer staining revealed one to be a response to a commonly recognized epitope, NS3(1248-1261), although cytokine capture assays showed these specific cells to be at a very low frequency. In this patient, and in others reported, this most frequently recognized HLA-DR11 restricted epitope is not immunodominant. We analysed whether sequence variability within and between genotypes might account for

HLA-DR is a αβ heterodimer cell surface receptor in the HLA system. The subunits are coded by the genes: HLA-DRA, HLA-DRB1, HLA-DRB3, HLA-DRB4, HLA-DRB5. DRA is functionally preserved, and the variation comes from the 4 β-chain loci. There are only 2 distinct α peptides, but 100s of B1 variants and 10s from B3-B5. The combinations determine the DR serotype: DR1-DR18, and DR51-53 from DRB3-DRB5. DR type is associated with many autoimmune conditions and other diseases. ...

4586 A number of studies have shown that HLA-DR, DQ and DP alleles are associated with an increased risk of paediatric acute lymphoblastic leukaemia (ALL), but the significance of these multiple HLA locus/allele associations for the aetiology of childhood ALL remains uncertain. One possibility is that they denote differences in immune responsiveness to a causative infection(s), mediated by the differential antigenic peptide-binding efficiency of HLA class II alleles. We previously reported that B cell precursor ALL [BCP] was associated with HLA-DPB1*0201 and related alleles with glutamic acid (E) at position DPβ169 in the P4 peptide binding pocket (PBP). However, recent studies suggest that DPB1 alleles can be clustered into a small number of functional supertypes based on the shared peptide binding characteristics of several PBP. To determine whether these influence the risk of BCP ALL, we clustered DPB1 alleles into 3 pairs of supertypes, defined by di-allelic polymorphisms at DPβ184, 69 and ...

In an analysis of T cell responses to synthetic peptides in mice transgenic for HLA-DR51 and - DQ6, we found that DR51 and DQ6 transgenic mice acquired significant T cell response to influenza ...

Binds peptides derived from antigens that access the endocytic route of antigen presenting cells (APC) and presents them on the cell surface for recognition by the CD4 T-cells. The peptide binding cleft accommodates peptides of 10-30 residues. The peptides presented by MHC class II molecules are generated mostly by degradation of proteins that access the endocytic route, where they are processed by lysosomal proteases and other hydrolases. Exogenous antigens that have been endocytosed by the APC are thus readily available for presentation via MHC II molecules, and for this reason this antigen presentation pathway is usually referred to as exogenous. As membrane proteins on their way to degradation in lysosomes as part of their normal turn-over are also contained in the endosomal/lysosomal compartments, exogenous antigens must compete with those derived from endogenous components. Autophagy is also a source of endogenous peptides, autophagosomes constitutively fuse with MHC class II loading compartments.

N2 - Loss of major histocompatibility class II (MHC class II) molecules on diffuse large B-cell lymphoma (DLBCL) has been associated with poor survival; however, none of these reports analysed a uniformly treated patient cohort. This study was designed to validate one MHC class II antigen, HLA-DR, as a prognostic marker in patients uniformly treated with the MACOP-B regimen. Immunostaining results were correlated with the international prognostic index (IPI) score and overall survival (OS). Of the 97 cases, 82 had interpretable staining. Of these, 52 expressed HLA-DR (median OS, 16.2 years) while 30 were negative (median OS, 4.2 years, P = 0.037). The IPI was also predictive of OS in the ...

GCA and PMR are associated with the same human leukocyte antigen genes as those seen in patients with rheumatoid arthritis (ie, human leukocyte antigen-DR4 variants *0401 and *0404). The pathogenesis of GCA appears to be initiated by T cells in the adventitia responding to an unknown antigen, which prompts other T cells and macrophages to infiltrate all layers of the affected artery and to elaborate cytokines that mediate both local damage to the vessel and systemic effects (Figure 30-1). The differential expression of inflammatory cytokines may explain the clinical subsets seen in GCA. Patients with the highest levels of interleukin-6, for example, are more likely to have fever and less likely to experience blindness. MRI and ultrasonography show that PMR is caused by inflammation of the synovial lining of the bursa and joints around the neck, shoulders, and hips. ...

HLA-DR+ gut epithelial cells may present antigen to intraepithelial lymphocytes (IEL). This study aimed to isolate an IEL population from the human colon to activate CD3 + IEL by a human colonic epithelial cell line (HT-29), bearing different concentrations of class II antigen (HLA-DR). IEL were isolated by a mechanical method from six patients with ulcerative colitis (UC) and from 14 control patients. IEL were cocultured with HT-29 which had been induced to express class II molecules by gamma-interferon (IFN-gamma) in a dose dependent manner. The phenotype and the subsequent expression of activation markers by the IEL were determined to two colour flow cytometry. The IEL population had a CD4/CD8 ratio similar to that seen in tissue sections. In the mixed cell culture, the degree of IEL activation showed a positive correlation with the degree of HLA-DR expression by the HT29 cells and the IEL secreted a IFN-gamma like factor that in turn stimulated the HT-29. Thus, depending on their expression of HLA

We used a hit and run gene targeting strategy to generate mice expressing only the p31 isoform of the conserved invariant (Ii) chain associated with major histocompatibility complex (MHC) class II molecules. Spleen cells from these mice appear indistinguishable from wild type with respect to class II subunit assembly, transport, peptide acquisition, surface expression, and the ability to present intact protein antigens. Moreover, these mutant mice have normal numbers of thymic and peripheral CD4+ T cells, and intact CD4+ T-dependent proliferative responses towards a soluble antigen. In short, MHC class II expression and function are surprisingly unaffected in mice lacking p41 invariant chain, implying that the p31 and p41 isoforms may be functionally redundant in the intact animal.

TY - JOUR. T1 - Multivariate logistic regression for familial aggregation in age at disease onset. AU - Matthews, Abigail G.. AU - Finkelstein, Dianne M.. AU - Betensky, Rebecca. PY - 2007/6/1. Y1 - 2007/6/1. N2 - Familial aggregation studies seek to identify diseases that cluster in families. These studies are often carried out as a first step in the search for hereditary factors affecting the risk of disease. It is necessary to account for age at disease onset to avoid potential misclassification of family members who are disease-free at the time of study participation or who die before developing disease. This is especially true for late-onset diseases, such as prostate cancer or Alzheimers disease. We propose a discrete time model that accounts for the age at disease onset and allows the familial association to vary with age and to be modified by covariates, such as pedigree relationship. The parameters of the model have interpretations as conditional log-odds and log-odds ratios, which can ...

Advancement of Graves disease relates to HLA-DR3. 4, 6, 7, and 9) bind in the HLA-DR binding groove. Aspect chains of proteins in positions 2, 3, 5, and 8 are thought to get in touch with SB939 the T cell receptor (TCR), activate Compact disc4+ T cells, and finally get B cells to create antibodies (12). Many reports have demonstrated immune system suppression through the use of changed ligand peptides in autoimmune illnesses. For instance, mutated myelin simple proteins peptides were present to antagonize T cell reactions in experimental types of multiple sclerosis (13). To stimulate tolerance of Compact disc4+ T cells by attenuating binding to TCR, we designed a mutated hTSH-R peptide 37 (ISRIYVSIDATLSQLES: 37m) utilizing a pc algorithm (12). In 37m (ISRIYVSIDVTLQQLES), proteins constantly in place 5 and 8 from the binding theme were changed from those in hTSH-R peptide 37 (6). 37m was likely to bind to HLA-DR3 solidly however, not bind well to TCR. In the current study, we demonstrate ...

Potent adjuvanted killed vaccines like those for rabies virus also can trigger immediate and delayed (vaccinosis) adverse vaccine reactions. Genetic predisposition to these disorders in humans has been linked to the leucocyte antigen D-related gene locus of the major histocompatibility complex, and is likely to have parallel associations in domestic animals.. It must be recognized, however, that we have the luxury of asking such questions today only because the risk of disease has been effectively reduced by the widespread use of vaccination programs.. Adverse Events Associated with Vaccination The clinical signs associated with vaccine reactions typically include fever, stiffness, sore joints and abdominal tenderness, susceptibility to infections, neurological disorders and encephalitis, collapse with autoagglutinated red blood cells and icterus (autoimmune hemolytic anemia, AIHA, also called immune-mediated hemolytic anemia, IMHA), or generalized petechiae and ecchymotic hemorrhages ...

Between July 2001 and May 2003, 187 mother and neonate pairs participated in this study. A total of 184 neonates completed the HLA-DR and -DQ genotyping. The frequencies of HLA-DR and -DQ genes, maternal sensitization, sIgE , 100 IU/ml, and cIgE ≥ 0.35 IU/ml were not different between the four areas. No association was found between cIgE and HLA-DR and -DQ genes or atopic symptoms. Physician diagnosed atopic symptoms were associated with the HLA-DQB1*02 allele (X2= 10.38, p,0.0013).

In this study, we isolated cells from the mesenchymal region of amnion and identified two subpopulations discordant for expression of the HLA-DR, CD45, CD14, and CD86 cellular markers. We therefore refer to the unfractionated cell population derived from this region as amniotic mesenchymal tissue cells (AMTC). We studied the suppressive and stimulatory characteristics of the unfractionated, HLA-DR-positive, and HLA-DR-negative AMTC populations and demonstrated that all three ...

Autoantibodies to IA-2 in type 1 diabetes are associated with HLA-DR4, suggesting influences of HLA-DR4-restricted T cells on IA-2-specific B cell responses. The aim of this study was to investigate possible T-B cell collaboration by determining whether autoantibodies to IA-2 epitopes are associated with T cell responses to IA-2 peptides presented by DR4. T cells secreting the cytokines IFN-γ and IL-10 in response to seven peptides known to elicit T cell responses in type 1 diabetes were quantified by cytokine ELISPOT in HLA-typed patients characterized for Abs to IA-2 epitopes. T cell responses were detected to all peptides tested, but only IL-10 responses to 841-860 and 853-872 peptides were associated with DR4. Phenotyping by RT-PCR of FACS-sorted CD45RO(hi) T cells secreting IL-10 in response to these two peptides indicated that these expressed GATA-3 or T-bet, but not FOXP3, consistent with these being Th2 or Th1 memory T cells rather than of regulatory phenotype. T cell responses to the same two

AIH so far thought to be an auto-immune disease. One of the genetic predisposing factors is thought to be HLA-DR3 and DR4 genes. The present study aimed at investigation the frequencies of HLA-DR3, DR4 and HLA-B27 genes among the Real-time PCR were used for the HLA-genes. The age of the patients were ranged from 7- 69 years in AIH group and from 8-67 years in healthy controls group. On the context of genotyping of HLA- genes, DR3, DR4, and B27 were found to be differed in their frequencies significantly among AIH patients that creating high etiological fraction of 0.504, 0.583, and 0.129 respectively compared to healthy controls, with odd ratio (OR) 7.35 for DR3, high OR 8.0 for DR4 and 2.23 for B27. The frequencies of these genes in AIH patients, highly significant differed between patient group, for DR3 compared to healthy group which 58.3% and 16% respectively, and very high significantly differed between patient group for DR4 compared to healthy group which 66.7% and 20% respectively, while no

Twenty eight out of 170 consecutive cases of acute lymphoblastic leukaemia (ALL) were examined. They were of T cell origin, with the following distribution: seven (28%) cases had pre-T or prothymic features; nine (36%) cases showed early thymocytic features, six (24%) had cortical features; and three (12%) had a mature phenotype. The remaining three cases could not be sub-classified. A striking finding was that pre-T ALL differed from intrathymic ALL not only in the absence of both E rosettes and intrathymic differentiation antigens, but also in the expression of two non-lineage specific antigens HLA-DR and CD10. Both antigens appear in the bone marrow from the very first stages of lymphoid differentiation, implying that the origin for pre-T ALL is bone marrow. A comparison of the clinical features of pre-T and thymic ALL showed that pre-T ALL disease showed a pattern more similar to non-T ALL disease: a lower incidence of mediastinal mass, absence of extrahaematopoietic disease, lower white ...

Individual leucocyte antigen (HLA) compatibility may be the key determining the incident of graft\vs\web host disease (GVHD) in sufferers. replies, correlate with markers involved with GVHD and will potentially end up being useful in the analysis of the natural processes involved with this disease. mismatched pairs. We discovered that a lot of genes linked to immune function were differentially regulated; these genes were also found to be associated with GVHD. The most highly upregulated genes were IFN\inducible genes and IFN neutralisation in MLCs abrogated their induction. The microRNA\155 (miR\155) was also found to be significantly induced in the mismatched setting but its induction was not diminished by blocking IFN. We are proposing that measuring gene expression in MLC could be a simpler and faster method of identifying functional incompatibilities between potential donorCrecipient pairs that are not detected by DNA typing techniques, compared with the traditional cellular assays. ...

Multiple sclerosis (MS) is characterized by the presentation of autoantigens by MHC II molecules that trigger activation of and cytokine production by autoreactive T cells and subsequent destructive inflammatory processes. Sixty percent of MS patients express the disease-associated MHC II allele HLA-DR2b (DRB1*15:01) that presents various myelin Ags, leading to an immune response against the myelin nerve sheath and disease symptoms. Different therapeutic attempts, such as modifying downstream inflammation, specific immunotherapy, and T cell-targeted approaches, have been only modestly successful due to undesirable immune responses and safety concerns. In this study, Ji et al. (p. 5074) describe the development of PV-267, a small molecule inhibitor of peptide binding and presentation by HLA-DR2b. Using the crystal structure to visualize key interactions of HLA-DR2 with bound MBP85-99 peptide, the authors identified a five-residue sequence, PV-267, exhibiting high HLA-DR2 binding affinity and ...

The MHC in humans encodes the most polymorphic genes, the HLA genes, which are critical for the immune system to clear infection. This can be attributed to strong selection pressure as populations moved to different parts of the world and encountered

Here is a map showing the allele frequency of HLA-DR1. The maximum frequencies are observed in the Volga-Ural region, among the Mari (24%), Chuvash (18.5%), Kostroma Russians (17.5%) and South Ural Russians (16%). Subtypes There are three main subclades of DR1: - DRB1*01:01 : the vast majority of Europeans belong to this subclade. It is virtually the only type encountered in northern and eastern Europe. Its presence in India and Iran is a sign that it was found among the

Use of the NGS to type patients with newly diagnosed type 1 diabetes and control subjects resulted in the following principal findings. First, among the 25 HLA-DRB1 alleles, only 4 (DRB1*03:01:01, DRB1*04:01:01, DRB1*04:04:01, and DRB1*04:05:01) were positively associated with type 1 diabetes. The H-score was used as a way to rank the relative degree of protection. Second, NGS detected nine alleles of DRB3, DRB4, and DRB5, including chromosomes with only nonamplified loci. Only DRB4*01:03:01 and DRB3*01:01:02 were positively associated; the remaining five alleles were negatively associated with the disease. Most importantly, DRB4 was dichotomized in that DRB4*01:03:01 was positively but DRB4*01:01:01 was negatively associated with type 1 diabetes. Similarly, DRB3*01:01:02 was positively but DRB3*02:02:01 was negatively associated with the disease. Because either one of these two alleles may be present on a haplotype containing DRB1*03:01:01, it cannot be excluded that the risk of this allele for ...

W rzs występują zaburzenia nabytej odpowiedzi immunologicznej przejawiające się autoreaktywnością limfocytów, gromadzeniem komórek pamięci, nadczynnością limfocytów B, preferencyjnym różnicowaniem limfocytów Th17 i upośledzeniem czynnościowym limfocytów Treg. W warunkach prawidłowych odpowiedź nabyta rozwija się w szpiku i obwodowych narządach limfatycznych (węzły chłonne, śledziona). Natomiast w przypadku rzs również w ekotopowej tkance limfatycznej. W rzs odpowiedź nabyta jest inicjowana przez czynniki genetyczne i środowiskowe. Głównym genetycznym czynnikiem ryzyka rozwoju rzs są geny kodujące cząsteczki HLA-DR ze „wspólnym epitopem (DRSE+). Spośród wielu środowiskowych czynników ryzyka rozwoju rzs najlepiej udokumentowany jest wpływ palenia tytoniu, zwłaszcza u pacjentów, którzy w haplotypie mają cząsteczki HLA-DR zawierające „wspólny epitop i wytwarzają przeciwciała swoiste dla cytrulinowanych peptydów.
