Abstract
Effective drug selection is the current challenge in rheumatoid arthritis (RA). Treatment failure may follow different pathomechanisms and therefore require investigation of molecularly defined subgroups. In this exploratory study, whole blood transcriptomes of 68 treatment-naïve early RA patients were analyzed before initiating MTX. Subgroups were defined by serologic and genetic markers. Response related signatures were interpreted using reference transcriptomes of various cell types, cytokine stimulated conditions and bone marrow precursors. HLA-DRB4-negative patients exhibited most distinctive transcriptional differences. Preponderance of transcripts associated with phagocytes and bone marrow activation indicated response and transcripts of T- and B-lymphocytes non-response. HLA-DRB4-positive patients were more heterogeneous, but also linked failure to increased adaptive immune response. RT-qPCR confirmed reliable candidate selection and independent samples of responders and non-responders the functional patterning. In summary, genomic stratification identified different molecular pathomechanisms in early RA and preponderance of innate but not adaptive immune activation suggested response to MTX therapy.

Abstract
To investigate a possible relationship between the presence of anti-neutrophil cytoplasm antibodies (ANCA), rheumatoid factors (RF), anti-nuclear antibodies (ANA), disease severity and HLA-DR phenotypes, 46 consecutive ANCA+ and 48 ANCA-, clinically well-documented RA patients were studied for RF, ANA and HLA-DR phenotypes. The 46 ANCA+ patients showed predominantly an atypical perinuclear staining pattern (89%). ANCA positivity was associated with higher RF titres (P < 0.005) and advanced functional Steinbrocker grades III/IV (P < 0.015). ANCA+ patients were also more often positive for ANA than ANCA- patients (P < 0.008). There was no correlation between ANCA positivity and certain HLA-DR phenotypes although the frequency of DR4+ (67% vs 52%) and, in particular, of DR4+ blanks (phenotypically homozygous) was increased in ANCA+ as compared to ANCA- patients (20% vs 8%). DR4-DR1-RA patients were twice as frequent in the ANCA- than in the ANCA+ group (22.9% vs 8.7%). Correspondingly, the DR4+DR1- phenotype was increased among ANCA+ RA patients. Regarding functional Steinbrocker grades, the DR4+ phenotypes were slightly but not significantly increased in grades III and IV whereas ANCA positivity was significantly associated with severe functional Steinbrocker grades III/IV (66% ANCA+ vs 39% ANCA-, P < 0.015). ANCA positivity identified a population of RA patients with a long-standing and severe clinical course of the disease. There was no correlation between ANCA positivity and certain HLA-DR phenotypes.

Abstract
The function of gamma delta T cells is still elusive. The nature of the antigens that they recognize and the mode of presentation of these antigens are largely unknown. The majority of human peripheral gamma delta T cells bear a V gamma 9/V delta 2 T cell receptor, and display nonclonal reactivity to mycobacteria, without restriction by MHC. It is unknown whether these cells have clonal antigenic specificity as well. Here we describe rheumatoid arthritis-derived V gamma 9/V delta 2 T cell clones, displaying dual antigenic recognition: a nonclonal, MHC-unrestricted recognition of mycobacteria, and a clonal recognition of a short tetanus toxin peptide presented by HLA-DRw53, a nonpolymorphic class II MHC molecule associated with susceptibility to rheumatoid arthritis. This is the first evidence that V gamma 9/V delta 2 T cells can recognize nominal antigenic peptides presented by class II MHC molecules. These results suggest that much like alpha beta T cells, V gamma 9/V delta 2 cells may contribute to the immune response against foreign antigens in an antigen-specific and MHC-restricted manner. The reactivity of these gamma delta T cells to mycobacteria may represent a superantigen-like phenomenon.

Abstract
HLA class II antigens were identified in a group of 44 patients with rheumatoid arthritis (RA) originating largely from the north or northeast of the Indian subcontinent and resident now in east London. Compared with 67 locally typed east London Asian controls, the prevalence of three HLA-DR antigens was raised in the patients: DR1 18.2% v 6.0% chi 2 = 3.99, DR4 20.5% v 11.9% chi 2 = 1.48, and DRw10 27.3% v 8.9% chi 2 = 6.56. These differences were also found when the patients with RA were compared with a larger control group of 110 northern Indians: DR1 18.2% v 7.2% chi 2 = 4.02, DR4 20.5% v 7.2% chi 2 = 5.56, and DRw10 27.3% v 8.1% chi 2 = 9.7. Twenty five (57%) of the patients expressed at least one of these antigens. All patients were also characterised for HLA-Dw types by mixed lymphocyte culture typing. The prevalence of the HLA-DR4 associated Dw types in the patients was: Dw4 2.3%, Dw10 0%, Dw14 11.4%, and Dw15 6.8%. The DR beta 1 chains of DR1 and DRw10 together with the Dw types of DR4 other than Dw10 share amino acid residues in a region of the third hypervariable region considered to be critical in antigen presentation. It is concluded that RA in Indians is associated with these HLA antigens, and data from this study support the hypothesis of a cross reactive epitope common to HLA specificities associated with RA.

Abstract
This chapter focuses strictly on the HLA MHC class II genes and molecules with regard to how they contribute to better delineation of the genetic associations and how the current knowledge of their structure, expression, and functions can be used to speculate on their role in the pathogenesis of disease. Because of the strong linkage disequilibrium between loci and alleles, the chapter restricts the description of the genetic associations to only the most recent data, mainly generated by molecular means, and because they supercede in precision and accuracy the previous data obtained by serological methods. Because the HLA system displays the unusual feature of strong linkage disequilibrium between loci and alleles, the genetic traits found to be associated with disease do not emerge at random. The pattern of genetic associations follow an almost constant trend. The associations gain strength each time an additional locus centromeric to the precedent is individualized. The advances made in this respect almost parallel the introduction of progressively more refined typing procedures, which allow the division of former genetic entities (loci and alleles) into additional subtypes. Among the HLA-associated diseases, or at least for those diseases in which an autoimmune process is suspected to be directly relevant to the pathogenesis, the associations are with genes and molecules of the HLA-D region (HLA class II genes and products). The most recent data assigns the disease susceptibility to common amino acid sequences present on an HLA class II molecule within its “active” site.

Abstract
Susceptibility to rheumatoid arthritis (RA) may be due to the presence of shared functional epitopes common to the HLA-DR beta chains of several RA-associated haplotypes. We have obtained direct evidence for this hypothesis by using the polymerase chain reaction and sequencing the DRB1 and DQB1 genes from RA patients. A highly conserved epitope present on DR beta chains of DR4 and DR1 haplotypes was found in 83% of 149 patients with classical or definite RA but was found in only 46% of 100 control individuals (P less than 0.0001). Two Dw subtypes of DR4 (Dw4 and Dw14) were associated with disease susceptibility but two other subtypes (Dw10 and Dw13) were not. Sequence differences between these subtypes implicate those residues around the putative antigen binding site of the DR beta molecule in the pathogenesis of RA. These data provide a basis for understanding host susceptibility to RA at a molecular level.

Abstract
Analysis of HLA DRB1 and DQB1 Bam HI RFLPs revealed four DRB1 (4.8, 5.2, 6.0 and 7.0 kb) fragments and a 3.2 kb DQB1 fragment to be significantly increased in Caucasians with seropositive RA compared to healthy individuals. The 4.8, 5.2 and 7.0 kb DRB1 fragments were found in 86.5% of RA patients and in 56% of the controls (p = 10(-3), relative risk (RR) = 5.0), while the 6.0 kb fragment was found in 79% of RA patients compared to 32% of controls (p = 2 x 10(-5), RR = 8.0). The 3.2 kb DQB1 fragment was observed in 63.5% of RA patients versus 38.0% of controls (p = 10(-2), RR = 2.8). Analysis of these fragments relative to HLA phenotypes revealed that the 4.8, 5.2 and 7.0 kb DRB1 fragments were strongly correlated with DR4, -7, -9 and -w53 serotypes, the 6.0 kb RFLP with DR4 and the 3.2 kb DQB1 fragment with DR1 and DQw1. Using probes specific for the 5' or 3' regions of the DRB1 gene, the 5.2 and 6.0 kb DRB RFLPs were mapped to the 5' end and the 4.8 and 7.0 kb RFLPs to the 3' end of the DRB1 gene. A probe generated from the second exon of the DRB4 (DRw53) gene recognized only the 5.2 and the 6.0 kb RFLPs corroborating the 5' location of these RFLPs. Family studies further confirmed that these RFLP's segregated with HLA phenotypes.

Abstract
To better define the presence of the DRw10 haplotype which has sometimes proved difficult to type by using serologic reagents, Southern blot analysis was performed on seven DRw10 heterozygous individuals with rheumatoid arthritis. Using the restriction enzymes Taq I or BamH I, the restriction fragment length polymorphism (RFLP) pattern for the DRw10 haplotype was clearly distinguishable from that of other DR alleles. Digestion with Taq I revealed a unique DR beta/Taq I 12.20 fragment. A characteristic DR beta/Taq I 4.60 fragment was also present only in DRw10 and DR1 haplotypes. Digestion with the restriction enzyme BamH I revealed a DR beta/BamH I 5.07 fragment also present in DRw10 and DR1 haplotypes, and a DR beta/BamH I 4.30 fragment shared with the DRw52 and DR2 haplotypes but not found in DR1 haplotypes. The pattern was readily distinguished from those given by the haplotypes DR4, 7 and w9. Family studies of five individuals demonstrated appropriate segregation of the restriction fragments. In particular, segregation of DRw10 haplotypes from DR1 haplotypes was clearly shown in a family in which the DRw10 haplotype was associated with rheumatoid arthritis in two individuals. Southern blot analysis proved to be a useful alternative method for identifying the DRw10 allele in certain combinations where this allele has been difficult to define serologically.

Abstract
The DR1 and DRw10 beta 1 chain genes were isolated from each of 2 individuals with rheumatoid arthritis who were heterozygous for these class II major histocompatibility complex specificities. The sequences of the DR1 beta 1 chains from both patients were identical, differing from previously reported DR beta 1 chains of individuals without RA by 2 amino acid substitutions, at positions 85 (Val-Ala) and 86 (Gly-Val), and by a silent mutation at the last nucleotide of codon 78 (C-T), resulting in the loss of a Pst I restriction endonuclease site. Identical DRw10 beta 1 chain genes were found in both patients. These were shown to encode the epitope recognized by monoclonal antibody 109d6. This antibody also recognizes an epitope on the DRw53 beta 2 chain of the DR4 haplotype. The third diversity regions of the DR1 beta (amino acids 67-74) and the DRw10 beta 1 chains (amino acids 67-73) were identical, respectively, with those of the DR4 (Dw14) beta 1 and beta 2 chains, raising the possibility that in these patients, the third diversity regions of the two DR beta 1 chain genes present in trans are conformationally equivalent to the cis-encoded third diversity regions of the DR4 (Dw14), DR beta 1, and beta 2 chains. The nucleotide sequences of the DQ beta complementary DNA clones were identical to that of the DQw1 beta chain, and no DR beta 2 complementary DNA clones were identified.

Abstract
Bam HI DR-beta and DQ-beta restriction fragment length polymorphisms (RFLPs) were found with increased frequency in white persons with seropositive rheumatoid arthritis as compared with control subjects. DR-beta 4.8-, 5.2-, and 7.0-kilobase (kb) RFLPs were observed in 86.5 percent of rheumatoid arthritis patients and in 56 percent of control subjects (p = 0.001, relative risk [RR] = 5.0). The 6.0-kb RFLP was present in 79 percent of rheumatoid arthritis patients and 32 percent of control subjects (p = 0.0002, RR = 8.0). The 4.8-, 5.2-, and 7.0-kb RFLPs correlated with DR4, -7, -9, and -w53 phenotypes and the 6.0-kb RFLP correlated only with DR4. Thus, these RFLPs do not appear to be disease-specific. A DQ-beta 3.2-kb RFLP was found in 63.5 percent of rheumatoid arthritis patients and in 38.0 percent of control subjects (p = 0.01, RR = 2.8). This fragment was frequently found in persons expressing DR1 and DQw1 phenotypes. Probes consisting of the first exon of the DR-beta-I and DR-beta-IV genes, respectively, only hybridized with the 5.2- and 6.0-kb RFLPs. These data suggest that more than one gene within the major histocompatibility complex contributes to susceptibility to seropositive rheumatoid arthritis in white persons.

Abstract
The results of family and twin studies suggest that RA may result from an interaction between an oligogenic susceptibility and unknown environmental factors. Part of this genetic predisposition is accounted for by genes within the MHC where there is a well-documented association with HLA-DR4. Studies of DR and other MHC variants have shown different associations with particular subgroups. One subgroup is Felty's syndrome where there is a strong association with DR4, as well as associations with DQ-beta and C4B null variants when DR4-matched Felty's and RA subjects are analysed. These DQ-beta and C4B null variants may characterize a single haplotype which is associated with extra-articular disease. A further rheumatoid subgroup characterized by circulating antibodies to native type II collagen, shows an association with HLA-DR3 and 7. Genes on chromosome 14 may also influence susceptibility to RA, probably by interaction with MHC genes and there are different Gm associations for DR4-positive and collagen-antibody-positive rheumatoid subgroups. HLA and Gm markers so far identified only account for a small part of the total genetic predisposition to RA and a third or further loci may also be involved. Possible candidates include T-cell alpha- and beta-chain genes and immunoglobulin light chain genes. One present concept of the genetic predisposition to RA is of several independent immunogenetic pathways each including interactions at two or more loci.

Abstract
This is an interpretive review of recent immunologic and molecular biologic data concerning the molecular basis of susceptibility to rheumatoid arthritis. The central point of view was taken that the major histocompatibility complex (MHC) class II molecules encoding disease susceptibility function in an immune recognition event involving an antigen "X" that currently eludes characterization. The problem of understanding the meaning of the association of susceptibility with diverse MHC alleles such as DR4 (Dw4 and Dw14), DR1, and DRw10 is approached by detailed biochemical analysis that led to the identification of common stretches of amino acid sequence, presumably encoding conformationally equivalent structures. Non-classic MHC polymorphisms related to disease susceptibility but not associated with particular alleles such as identified by Ab 109d6 proved especially valuable in suggesting new directions for attempting to understand the significance of these associations. Consideration is given to the possibility that a family of either slightly different or identical conformations encoded in either cis or trans cumulatively confer the liability to develop rheumatoid arthritis, and implying a highly non-classic mode of inheritance. The available data do not permit a distinction between the possibilities that an antigen "X" was being presented to T cells or whether the distinctive conformations of the MHC class II molecule serve the same role as antigen "X" but are directly recognized by T cells. However, with additional data, some limited insight should be able to be inferred about the nature of an antigen "X" that specifically binds to the MHC conformation with a complementary interaction. It seems reasonable to consider the pathogenesis of rheumatoid arthritis as a typical immune response resulting from a simple immune recognition event of a single antigenic molecule.

The central point of view is taken that the MHC class II molecules encoding disease susceptibility function in a specific immune recognition event. This could involve an antigen "X" that currently eludes characterization or be directed to polymorphic determinants on the MHC molecule itself. The problem of understanding the meaning of the association of susceptibility to rheumatoid arthritis with diverse MHC alleles such as DR4 (Dw4 and Dw14) and DR1 is approached by detailed biochemical analysis that led to the identification of common stretches of amino acid sequence, presumably encoding conformationally equivalent structures. The sequence shared by the otherwise unrelated DR1 and DR4 haplotypes from residue 67 in the DR a chain that appears to confer susceptibility is Leu-X-X-Gln-Arg/Lys. Non-classic MHC polymorphisms related to disease susceptibility but not associated with particular alleles such as identified by Ab109d6 prove especially valuable in suggesting new directions for attempting to understand the significance of these associations. Consideration is given to the possibility that a family of either slightly different or identical conformations encoded in either cis or trans cumulatively confer the liability to develop rheumatoid arthritis. This implies a highly non-classic mode of inheritance. It seems reasonable to consider the pathogenesis of rheumatoid arthritis as evolving from a typical immune response based on a simple immune recognition event directed to a single antigen.

Abstract
The differential expression of Ia antigens was studied in freshly isolated rheumatoid nonlymphoid synovial lining cells (SLC) and rheumatoid synovial fibroblast cell lines cultured in the presence of Interferon-gamma, using a large panel of anti-Ia reagents with monomorphic or polymorphic specificities. All the HLA-DR or -DQ specificities detectable on the corresponding peripheral blood B cells were also expressed in freshly isolated SLC. However, in all instances, the number of DR-positive SLC exceeded the percentage of cells expressing DQ antigens. In addition, the epitope expression of Ia antigens varied within the DR or DQ populations of Ia molecules as revealed by polymorphic reagents. Double-label experiments or using the ingestion of Latex particles as a marker demonstrated that the synovial macrophages (type I SLC) primarily bear the DR+DQ+ phenotype, while there is an additional population of nonphagocytic SLC (previously termed type II SLC) that has a DR+ and monocyte marker negative phenotype but did not have detectable levels of DQ antigens as analyzed by both fluorescence microscopy and cell sorter analysis. This latter population frequently had a morphology showing dendritic processes and rapidly lost the expression of Ia antigens upon culture. Cells with a similar, primarily DR+ phenotype were readily obtained in synovial fibroblast cultures after treatment with Interferon-gamma. These data suggest that there are two populations of Ia+ synovial lining cells: the synovial macrophages (type I cells) with the DR+DQ+ phenotype, and cells probably related to fibroblasts with a DR+ phenotype without detectable DQ antigens (type II cells). The fact that the latter phenotype could be induced by Interferon-gamma treatment of cultured synovial fibroblasts suggests that this mediator may have a similar role in vivo in the activation of certain synovial cell populations.

Abstract
The cause of rheumatoid arthritis is unknown. It appears that abnormal or overstimulated cell-mediated immune mechanisms are operating. Dendritic cells, with their potent antigen presenting and immunostimulatory properties, have been found in increased numbers of rheumatoid synovial fluids and membranes. It is postulated that these cells play a key role in inducing and perpetuating the immune response with subsequent synovial proliferation and joint destruction.

Abstract
Ia antigens (class II HLA molecules) have been detected on cells eluted from affected human cartilage in certain disease states, but not on normal cartilage cells. Because the presence of Ia antigens on chondrocytes may play an important role in rheumatic diseases, we investigated the induction of these molecules by gamma-interferon (gamma-IFN), a potent Ia-inducing lymphokine. Human articular chondrocytes were incubated with recombinant gamma-IFN, and the expression of Ia antigens was studied by cell sorter analysis, using a panel of reagents that detect monomorphic and polymorphic specificities of the DR and DQ Ia antigen families. While the induction of DR antigens, including polymorphic DR specificities, was readily obtained with gamma-IFN (50-95% positive cells), DQ antigens were negative or were displayed only on a lower percentage of chondrocytes (5-60%). In addition, incubation with gamma-IFN led to an increased expression of HLA class I antigens. The expression of various other surface markers either remained unchanged (as in 4F2 and BA-2) or showed tendencies toward decreased percentages (as in 83c2) or increased percentages (as in M phi R-17). No apparent change in cell morphology or growth pattern was observed.

Abstract
The etiology of systemic lupus erythematosus (SLE) is determined in part by genetic factors which influence susceptibility to the disease. These factors presumably have a major role in determining the clinical and laboratory manifestations of SLE. Certain newer observations which may pertain to an understanding of the genetic basis of SLE will be critically reviewed in this chapter. These observations are based on advances in the analysis of human SLE and the increased knowledge provided by various murine models of human autoimmune processes. However, the specific genes involved and the mechanisms by which they exert their effect are at present still unknown. Special attention will be given newer insights into the role of genes of the major histocompatibility complex (MHC) and their relationship to the genes encoding the T cell antigen receptor. The role of classic immunoglobulin genes as well as more complex mechanisms involving preferential maternal or paternal genetic effects are also discussed. The contribution of genes encoding complement and complement receptors toward the expression of the disease state are discussed in brief.

Abstract
Certain Ia allotypes such as DR4 show a strong association with particular autoimmune diseases such as rheumatoid arthritis. Despite this strong association, a significant number of individuals with the inappropriate Ia allotype develop the disease. It is proposed that these individuals share an Ia determinant or "epitope" with individuals of the appropriate Ia allotype, and that these epitopes, which are "mobile" and can be transmitted from one Ia haplotype and/or gene locus to another by mechanisms such as gene conversion, form the molecular basis for disease-susceptibility genes.
