  1. The HLA-DR observed on CD4 (show CD4 Proteins)+ T cells was almost exclusively cell surface-associated, while for autologous CD19 (show CD19 Proteins)+ B cells, the protein could be located in the plasma membrane as well as in the cytoplasm.

  2. HLA-DRB1*04:02, DRB1*14:04, HLA-DQB1* 03:02 and DQB1*05:03 alleles and HLA-DRB1*04:02-DQB1*03:02 and HLA-DRB1*14:04-DQB1*05:03 haplotypes are genetic markers for susceptibility for pemphigus vulgaris, while DRB1*11 allelic group appears protective in Serbian population.

  3. These findings indicate the role of HLA-DRB (show HLA-DRB5 Proteins) haplotypes in AIH susceptibility and protection, in the Iranian population.

  4. HLA-DRB1*14 and DQB1*05 were associated with anti-MUSK (show MUSK Proteins) antibody-positive myasthenia gravis.

  5. ur results indicated that HLA-DRB1*04:05, *04:03, *04:06 and SE alleles might be susceptibility allele for Rheumatoid arthritis in Chinese Han population of Shaanxi province, northwest of China

  6. Valpha2.3+Vbeta22+ CD4 (show CD4 Proteins)+ T-cells accumulate in the lungs of HLA-DRB1*03+ patients with pulmonary sarcoidosis

  7. Results identified a novel HLA class II association for flupirtine-induced liver injury (DILI) showing HLA-DRB1*16: 01 and DQB1*05: 02 as novel genetic risk factor for DILI and confirming the important contribution of HLA genotype towards the risk of DILI generally.

  8. HLA-DRB1*11 and HLA-DRB1*14 may be used to predict the susceptibility to Helicobacter pylori infection in children with idiopathic thrombocytopenic purpura

  9. The new alleles (DRB1*03:112, DQB1*03:02:16 and DQB1*03:139)were found after the sequence-based typing of 32 530 random UK European routine blood donors suggesting that each has a maximum carriage frequency of 0.0031% in the blood donor population resident in Wales.

  10. HLA-DRB1*04 (OR 1.24, 95%CI 1.00-1.55, P = 0.0494), HLA-DRB1*08 (OR 1.45, 95%CI 1.14-1.86, P = 0.0030) and HLA-DRB1*16 (OR 1.39, 95%CI 1.04-1.87, P = 0.0269) were significantly associated with increased tuberculosis occurrence (Meta-Analysis)

HLA-DRB1 Protein Profile

Protein Summary

HLA-DRB1 belongs to the HLA class II beta chain paralogs. The class II molecule is a heterodimer consisting of an alpha (DRA) and a beta chain (DRB), both anchored in the membrane. It plays a central role in the immune system by presenting peptides derived from extracellular proteins. Class II molecules are expressed in antigen presenting cells (APC: B lymphocytes, dendritic cells, macrophages). The beta chain is approximately 26-28 kDa. It is encoded by 6 exons. Exon one encodes the leader peptide\; exons 2 and 3 encode the two extracellular domains\; exon 4 encodes the transmembrane domain\; and exon 5 encodes the cytoplasmic tail. Within the DR molecule the beta chain contains all the polymorphisms specifying the peptide binding specificities. Hundreds of DRB1 alleles have been described and typing for these polymorphisms is routinely done for bone marrow and kidney transplantation. DRB1 is expressed at a level five times higher than its paralogs DRB3, DRB4 and DRB5. DRB1 is present in all individuals. Allelic variants of DRB1 are linked with either none or one of the genes DRB3, DRB4 and DRB5. There are 4 related pseudogenes: DRB2, DRB6, DRB7, DRB8 and DRB9.
