Whether autoimmune mechanisms play a role in the pathogenesis of inclusion body myositis (IBM) is unknown. Human leukocyte antigen (HLA) analysis in 52 patients, including 17 with autoimmune disorders (AIDs), showed that patients were more likely to have antigens from the autoimmune-prone HLA-B8-DR3 ancestral haplotype than healthy control subjects, irrespective of the presence of AIDs. Patient...

The pathobiology of chronic beryllium disease (CBD) involves the major histocompatibility complex class II human leukocyte antigen (HLA). Although occupational exposure to beryllium is the cause of CBD, molecular epidemiologic studies suggest that specific (Italic)HLA-DPB1(/Italic) alleles may be genetic susceptibility factors. We have studied three-dimensional structural models of HLA-DP prote...

The object of this cross sectional study was to determine the HCV subtype 3a envelope protein binding affinity with Human Leukocyte Antigen. Envelope 1 (E1) protein is one of the structural proteins responsible for entering the cells through the receptors. The binding affinity of E1 protein epitopes to the selected Human Leukocyte Antigen (HLA) class I alleles was investigated using the compute...

introduction: recognition of human leukocyte antigens (hla) is of importance for hematopoietic stem cell transplantation. any hla-mismatches between the donor and recipient can cause graft rejection or other complications. in hla-typing experiments, usage of hla-known reference cells accompany with hla-unknown samples is obligatory. some international centers represent these cells with high exp...

We have studied the modulation of Ia-like antigens on the surface membrane of human T cells responding in a one-way mixed leukocyte culture. A heterologous antiserum, (anti-p23,30), which is specific to HLA-D-related antigens and which is unreactive with normal peripheral T cells or thymocytes, was found to bind significantly to all T cells transformed in mixed leukocyte culture (MLC) as determ...

The characteristics and natural history of alloimmunization to HLA were studied in five patients with Hunter's syndrome receiving long term transfusions of leukocytes collected from human leukocyte antigen (HLA) matched donors. Patients were not given any other blood component transfusions. All patients became alloimmunized at an average interval of eight months following an average of 15 trans...

AIM Humoral sensitization affects transplant outcome, and it is now apparent that human leukocyte antigen (HLA) antibodies are specific for epitopes rather than antigens. Such epitopes can be structurally defined by HLAMatchmaker, an algorithm that considers eplets as critical elements of epitopes recognized by alloantibodies. This study addressed the question how mismatched HLA antigens induce...

BACKGROUND Epitopes of human leukocyte antigen (HLA) are the sites to which the antibodies bind. We identify here 103 HLA class I epitopes shared by groups of class I antigens. In particular, our emphasis was on identifying epitopes exclusive to the C-locus antigens or interlocus epitopes among A, B, and C antigens. The use of monoclonal antibodies or alloantibodies eluted from HLA recombinant ...

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 1...
