Genetically, the strong primary sclerosing cholangitis (PSC) risk factors HLA-B*08 and DRB1 (显示 RBM45 ELISA试剂盒)*03 were more prevalent in Antineutrophil cytoplasmic antibodies (ANCA) -positive than -negative patients. In UC patients without liver disease, HLA-DRB1 (显示 HLA-DRB1 ELISA试剂盒)*03 was more prevalent in pANCA-positive compared with -negative patients.Antineutrophil cytoplasmic antibodies identified PSC patients with clinical and genetic characteristics.
The goal of this study was to evaluate the impact of EHR point-of-care tools on medical record documentation of genetic testing care processes for the common HFE mutations, a thrombophilia panel, and HLA-B27.
This review focuses on the ambivalent role of HLA-B27 in autoimmunity and viral protection correlating its functions to the quantitative and qualitative effects of ERAP1 (显示 ERAP1 ELISA试剂盒) and ERAP2 (显示 ERAP2 ELISA试剂盒) polymorphisms on their enzymatic activity.
The association between HLA-B*57 and pemphigus vulgaris (显示 DSG3 ELISA试剂盒) is reported for the first time in the present study.
Arginine (di)methylated human leukocyte antigen class I peptides, which are asymmetrically dimethylated, most likely by CARM1, are favorably presented by HLA-B*07.
This study demonstrated that the expression of a single human class I MHC molecule, independent of persistent virus infection, influences the extent of sub frequent chronic neuronal injury or repair in the absence of a class II MHC immune response.
The HLA-B*50 allele was associated with conversion to myasthenia gravis generalized disease in patients with pure ocular symptoms at disease onset.
findings demonstrate that gliadins contain epitopes that elicit CD8 (显示 CD8A ELISA试剂盒)+ T cell responses restricted by HLA class I (显示 MICA ELISA试剂盒) A*0101 and B*0801 molecules
The HLA-B*42, HLA-C*17, HLA-DPA1*03, and HLA-DPB1*105 genotypes were associated with allergic asthma and the HLA-B*48 genotype with the nonallergic phenotype.
There was no increased risk of rheumatoid arthritis in mothers of children with aspartic acid at position 9 of HLA-B.
HLA-B belongs to the HLA class I heavy chain paralogues. This class I molecule is a heterodimer consisting of a heavy chain and a light chain (beta-2 microglobulin). The heavy chain is anchored in the membrane. Class I molecules play a central role in the immune system by presenting peptides derived from the endoplasmic reticulum lumen. They are expressed in nearly all cells. The heavy chain is approximately 45 kDa and its gene contains 8 exons. Exon 1 encodes the leader peptide, exon 2 and 3 encode the alpha1 and alpha2 domains, which both bind the peptide, exon 4 encodes the alpha3 domain, exon 5 encodes the transmembrane region and exons 6 and 7 encode the cytoplasmic tail. Polymorphisms within exon 2 and exon 3 are responsible for the peptide binding specificity of each class one molecule. Typing for these polymorphisms is routinely done for bone marrow and kidney transplantation. Hundreds of HLA-B alleles have been described.
