Dendritic cells (DCs) are the most potent antigen-presenting cells, but the ontogeny and functions of lung DCs are not known during prenatal period. Here, we isolated lung DC population from fetal (125-175 days of gestation age) and adult baboons. The cells were stained with fluorochrome-conjugated-HLA-DP, DQ, DR, CD1a, CD11c, CD14, CD40, CD80, CD86, CD209, CMKLR1, ILT7-specific antibodies, and...
Typing of DNA from 94 unrelated children with celiac disease (CD) with HLA-DQA1 and -DQB1 allele-specific oligonucleotide probes revealed that all but one (i.e., 98.9%) may share a particular combination of a DQA1 and a DQB1 gene. These genes are arranged in cis position on the DR3DQw2 haplotype and in trans position in DR5DQw7/DR7DQw2 heterozygous individuals. Thus, most CD patients may share ...
Three immune sera, raised in rabbits against synthetic peptides corresponding in sequence to predetermined regions of the HLA-DQ histocompatibility antigens, were tested for their ability to recognize phenotypically distinct human lymphoblastoid cell lines. The immune sera readily recognize the immunogen. When tested on the cells, they react poorly but seem to exhibit a certain degree of specif...
Autoimmune mechanisms are likely involved in the pathogenesis of idiopathic dilated cardiomyopathy (IDC) and components of MHC may serve as markers for the propensity to develop immune-mediated myocardial damage. This study was conducted to investigate the possible association between HLA-DQA1, -DQB1 alleles and IDC in Han population from northern China by using PCR-based sequence-specific prim...
Macrophage major histocompatibility complex (MHC) class II antigen expression is associated with defective antigen presentation to T lymphocytes in animals and is predictive of patient outcome after major trauma or sepsis. In this study, class II antigen (HLA-DR and DQ) expression on peripheral blood monocytes was investigated in patients with inflammatory bowel disease in relation to disease a...
BACKGROUND We investigated the immunoreguratory role of the major histocompatibility complex in peripheral blood lymphocytes' proliferative response to mite antigen. METHOD Peripheral blood lymphocytes of Japanese asthmatic patients were incubated with antigen obtained from Dermatophagoides pteronyssinus with a molecular weight of about 15,000, with and without 0.05 microgram/mL of monoclonal...
Background: Based on the reports, high frequency of special alleles of HLA class II genes might be associated with susceptibility to or protective from a particular cancer. These alleles might vary depending on the geographical region. Here we investigate the association between alleles of HLA class II genes and breast cancer in Iranian women.Methods: 100 patients with pathologically proved bre...
Atypical invariant chain (Ii) CLIP fragments (CLIP2) have been found in association with HLA-DQ2 (DQ2) purified from cell lysates. We mapped the binding register of CLIP2 (Ii 96-104) to DQ2 and found proline at the P1 position, in contrast to the canonical CLIP1 (Ii 83-101) register with methionine at P1. CLIP1/2 peptides are the predominant peptide species, even for DQ2 from HLA-DM (DM)-expres...
