Abstract
Three DRB1 alleles of the DR1 group including DRB1*0101, DRB1*0102, and DRB1*0103 are currently recognized. The first two of these are defined as HLA-DR1 by serologic typing and as either Dw1 or Dw20 by typing with T cells. DRB1*0103, previously called DR'Br' or DR'BON', is not detectable by serology. Little information exists about the population frequencies of DRB1*0102 and DRB1*0103. In the present study we have used the polymerase chain reaction (PCR) and allele-specific oligonucleotide probes to determine these alleles. To avoid cross-hybridization with other DRB genes having the same DNA sequences as those of the region to be analyzed, we performed group-specific PCR to amplify only DR1 DRB1 genes. This was accomplished using a 21-nucleotide-long primer, homologous to the first hypervariable region common to the DR1 DRB1 genes, and which under appropriate conditions amplified only DRB1 genes of the DR1 group. Five oligonucleotide probes, one matching the second hypervariable region, two spanning the third hypervariable region, and two covering codons 82 through 89, were used to determine the three alleles. DRB1*0101 (Dw1) was found to be the major type of DR1 in North American Caucasians. In North American black and Brazilian mestizo populations DRB1*0102 (Dw20) was more prevalent. DRB1*0103 (DR'Br') was detected in only six individuals in the present study.

Abstract
Serological identification of the HLA-DQw1(w5)-associated or HLA-DQw3(w7)-associated DR'Br' (DRB1*0103) allele cannot be accomplished in the presence of a second DQw1(w5)-positive or DQw3(w7)-positive haplotype, respectively. DNA-restriction fragment length polymorphism (RFLP) analysis assists in identification of DR'Br', though not in the presence of DR1. We describe an alternative or complementary method for identification of DR'Br' using two oligonucleotide probes which target HLA-DRB1 gene HV3 regions.

Abstract
Due to some limitations of restriction fragment length polymorphism (RFLP) analysis in HLA-DR-DQ typing, we present a combined use of RFLP and polymerase chain reaction (PCR)-allele-specific oligonucleotide (ASO) typing. This scheme consists in selectively amplifying the few RFLP ill-defined genes (DR1/DR'Br' and DR4-Dw subsets) using PCR with allele specific primers to avoid cross-hybridization.

Abstract
Trans-racial analysis of disease associations has improved mapping of MHC-linked susceptibility to Type 1 (insulin-dependent) diabetes mellitus. In this study the contributions of the MHC class II DQA1 and DQB1 genes were investigated. Sequence-specific oligonucleotide gene probing in Type 1 diabetic and control subjects of North Indian origin supported the DQw1.18 allele of the DQB1 gene as a determinant of inherited protection against Type 1 diabetes (RR = 0.12, pc less than 0.05). The A3 allele of the DQA1 gene was positively associated with the disease, (RR = 3.6, pc less than 0.05), as was the DQw2 allele of the DQB1 gene (RR = 4.6, pc less than 0.01). Trans-racial comparison of these disease associations indicates that DQ alleles may directly determine an element of inherited susceptibility to Type 1 diabetes.

Abstract
The second exon of HLA-DPB includes five polymorphic segments with extensive sharing of sequences between alleles. In order to facilitate assignment of specificities in heterozygous individuals, we have used group-specific amplification of two nonoverlapping sets of DPB alleles (here called group A and group B) with especially designed primers. Group A and group B polymerase chain reaction products were hybridized with sequence-specific oligonucleotide probes generating easily recognizable patterns which defined 24 distinct HLA-DPB alleles. We also established a routine procedure for distinguishing HLA-DP homozygosity from failed amplification in one of the alleles. Our results showed that when only one allele was detected, failure of amplification had occurred in less than 4% of the cases. DNA typing with this method correlated well with primed-lymphocyte typing for HLA-DP in the Tenth Workshop, as determined by us in assays performed on the workshop B-cell lines. Two normal panels of unrelated subjects were tested to obtain population frequencies. We conclude that this method is simple, relatively quick, and accurate. It is the method of choice for studies to determine the role of HLA-DP alleles in T cell reactions, in various diseases, and in transplantation.

Abstract
A novel TaqI restriction fragment length polymorphism (RFLP) of 4.15 kb is reported using a DR beta probe (pRTV1). This fragment corresponds to the DRB1 locus and allows the subdivision at the DNA level of the DRB1*0301 allele (DR3 antigen), which had not previously been reported. Both splits also distinguish each of the two DR3-bearing extended haplotypes (HLA-B8,SCO1,DR3,DQw2,Dw24 and B18,F1C30,DR3,DQw2,Dw25) found associated to several autoimmune diseases as insulin-dependent diabetes mellitus (IDDM), systemic lupus erythematosus (SLE) and myasthenia gravis. The fact that no polymorphism in the DRB1*0301 coding DNA sequence has been detected indicates that DRB1*0301 intronic, regulatory of neighbouring sequences might also contribute to differential disease associations (and pathogenic mechanisms) found linked to each of the two DR3-bearing haplotypes, i.e. IDDM and B8,DR3,Dw24 in North European/American Caucasoids vs IDDM and B18,DR3,Dw25 in Mediterraneans; SLE and B8,DR3,Dw24 in children vs SLE and B18,DR3,Dw25 in Spanish adults.

Abstract
Primary Sjögren's syndrome (1. SS) is a systemic autoimmune disease characterized by lymphocytic infiltration of the salivary glands and autoantibody production. In order to identify genetic factors that play a role in pathogenesis and predict extent of disease, we used Southern blot and polymerase chain reaction (PCR) methods to detect polymorphisms of the HLA-DRB1 (DR), HLA-DRB3 (DRw52), and HLA-DQA1 genes among 75 Caucasoid 1. SS patients and 150 Caucasoid controls living in the same geographic region of Southern California. We found significantly increased frequency of HLA-DR3 (P less than .001), HLA-DW52a (P less than .001), and HLA-DQA4 (P less than .05), in comparison to normal controls. Also, an increased frequency of heterozygosity for HLA-DQA1/DQA4 (P less than .05) was present among 1. SS patients. Autoantibodies to SS-A and to SS-B were significantly associated with DR3 (P less than .001), HLA-DQA4, (P less than .05), and DQA4/DQA1 heterozygotes (P less than .01). Among the 1. SS patients, clinical and laboratory features such as hypergammaglobulinemia, symmetric peripheral neuropathy, and hypothyroidism were significantly associated with HLA-DR3 (P less than .01) but not with HLA-DR2 (P greater than .10). In comparison, 1. SS patients with leukocytoclastic vasculitis were more frequently HLA-DR2 (P less than .05). These results using PCR methods confirm and extend prior studies that have used serologic methods.

Abstract
Using DNA techniques, we investigated the role of HLA-DR, DQ, and DP alleles in susceptibility to juvenile arthritis (JA). We studied 2 groups of patients with JA having a different disease prognosis and course. The pauciarticular form is usually benign, while the polyarticular disease frequently leads to joint destruction and disability. Persistent pauciarticular disease developed preferentially in patients having HLA-DRw13-Dw18 and DQw6-Dw18, but these antigens did not confer susceptibility in patients whose disease converted to the polyarticular form. HLA-DPw2.1 was an additional susceptibility factor for patients with JA of pauciarticular onset. In the polyarticular form of JA, HLA-DPw3 was the major factor for susceptibility, giving a relative risk of 10.3 (P less than 0.0001). In addition, we found that DRw8.1 and DQw4 were increased, and HLA-DR4 was markedly decreased, in patients with pauciarticular and polyarticular disease. These results indicate that in addition to some shared factors, distinct HLA class II alleles are important in pauciarticular or polyarticular JA. We conclude that typing with oligonucleotide probes may be useful in predicting the outcome in some children with arthritis.

Abstract
In a previous report we described how cross-immunizations of pairs of transgenic mice expressing different HLA class I antigens led to the production of antibodies directed exclusively at polymorphic epitopes. This was ascribed to self-tolerance of HLA that prevents immune responses to monomorphic epitopes and focuses responses on polymorphic ones. In the present report we extend our findings and demonstrate that immunizations of class I transgenic mice with HLA transfected mouse fibrosarcoma as well as with human lymphoblastoid cells also preferentially yield antibodies to polymorphic epitopes. This was the case whether or not immunizations were carried out across locus barriers [e.g., Tg(HLA-A *0201) or Tg(HLA-Cw*0301) transgenic mice immunized with HLA-B27 transfectants] or within the same locus [e.g., Tg(HLA-B*1302) transgenic mice immunized with HLA-B27 transfectants or B27-expressing lymphoblastoid cells]. Use of an extended immunization protocol with four or more booster injections favored antibodies of IgG isotype with affinities high enough to lyse normal peripheral blood lymphocytes (PBLs) in complement-dependent cytotoxicity assays and to immunoprecipitate HLA antigens. The specificities covered by the monoclonal antibodies (mAbs) could be either broad or narrow, depending on the genetic distance of the HLA antigens or alleles involved. For instance, a Tg(HLA-B*1302) transgenic mouse immunized with B27 produced both broad B7/B27-specific antibodies, Bw4-specific antibodies, and one antibody reacting with all B alleles except B13 and with some C alleles. On the other hand, a Tg(HLA-B*1302) transgenic mouse immunized with Bw47 transfectants responded narrowly with an antibody to Bw60 and Bw47. Thus it appears that by choosing appropriate recipient mice and closely related or more distant HLA antigens, antibodies of a programmed specificity can be generated.

Abstract
The HLA system encompasses approximately one thousandth of the human genome and contains a series of closely linked loci coding for molecules which provide the context for the recognition of antigens by T lymphocytes. Within the HLA system, several phenotypically expressed and genomic polymorphisms can be distinguished. These polymorphisms are described and the main objectives for the future research are discussed.

Abstract
We examined the polymorphism of DR2,DQw1 haplotypes in Epstein-Barr virus-transformed B-lymphoblastoid cell lines (HTCs) and unrelated (32 Canadian Caucasians and 24 Asian Indians) individuals by restriction fragment length polymorphism (RFLP) and oligonucleotide typing. The data demonstrate that three subtypes of DR2,DQw1 haplotypes, DRw15(B1.1501).DQw6a(A1.0102,B1.0602),DRw15(B1.1502). DQw6b(A1.0103,B1.0601), DRw16(B1.1601).DQw5(A1.0102,B1.0502) are present in HTCs and Canadian Caucasians. Of these, DRw15(B1.1501).DQw6a (A1.0102,B1.0602) haplotype was present in majority (81.3%) of Caucasians. Among Asian Indians, this haplotype was present only in one DR2,DQw1-positive individual. In addition, three new haplotypes representing different combinations of DRB1, DQA1 and DQB1 genes were demonstrable in Asian Indians. These new haplotypes are DRw15(B1.1501).DQw6b(A1.0103,B1.0601),DRw15(B1.1501). DQw5(A1.0102,B1.0502), and DRw15(B1.1501).DQw6c(A1.0102, B1.0601). The most frequent haplotypes among Asian Indians were DRw15(B1.1502).DQw6b(A1.0103,B1.0601) and DRw15(B1.1501). DQw6b(A1.0103,B1.0601). The distribution of subtypes of DR2,DQw1 haplotypes in Asian Indians was significantly different from that in Canadian Caucasians. The results in the present study have important implications for HLA and for HLA-disease associations.
