Abstract
Sera of patients suffering from systemic lupus erythematosus (SLE) frequently contain oligoclonal IgG autoantibodies with high affinity for the ribosomal protein L7 (rpL7). The humoral autoimmune response to rpL7 apparently is driven by antigen and T cell dependent. In order to analyze the T cell response to rpL7 we cultured peripheral blood lymphocytes of healthy individuals and SLE patients in the presence of recombinant rpL7. After 10 days, the cytokine response to re-stimulation with rpL7 was examined using a spot-ELISA. Measuring IFN-gamma secretion, the T cells of two patients and four healthy donors showed a significant increase in the number of spots as compared to control cells. Secretion of IL-4 or IL-10 was not detected. From the antigen-stimulated primary cultures we established by limiting dilution cloning six rpL7-reactive, IFN-gamma-secreting T cell lines which show a CD3+CD4+CD8- phenotype. One line additionally was shown to be positive for HLA-DR and CD45R0, but negative for CD27 and CD31. The cell lines carry alphabeta TCR chains which differ from each other in sequence and specificity. rpL7 fragments rich in basic amino acids could be identified as epitopes recognized by the TCR of three cell lines. Recognition of rpL7 is HLA-DR6 restricted or respectively HLA-DP restricted in the two cell lines analyzed.

Abstract
The T-cell recognition of HLA-DR-peptide complexes is generally restricted by the polymorphism of the DRB molecules but pluriallelic restriction has been described. The molecular basis of restriction and promiscuity of such peptide-specific responses is poorly understood. We isolated a panel of T-cell lines specific for the tetanus toxin peptide p2 (TT830-843) exhibiting pluriallelic restriction by DR11 and DR8 alleles. Fine restriction specificity of the T-cell lines was examined in functional assays against DR oligotyped APCs expressing different variants of DR11 and DR8 alleles. Our results show that (a) polymorphisms between serologically related alleles are relevant in terms of restriction of the peptide-specific T-cell response; in some instances, a single amino acid substitution can determine the restriction of a T-cell line; (b) different patterns of restriction are not the result of specific differences in DR-p2 binding as p2 peptide binds to all DR11 and DR8 alleles tested (DRB1* 1101, -1102, -1103, -1104, 110X, -0801, -0802, -0803, and -0806); and (c) pluriallelic restriction of the peptide-specific T-cell response correlates with the presence of a DRB1 alpha-helix motif (67-71-86) shared by some DR11 and DR8 alleles. Possible implications of pluriallelic restriction of peptide-specific T-cell response in autoimmune disorders associated with DR11 and DR8 are discussed.

Abstract
In sera of patients with mixed connective tissue disease (MCTD, Sharp Syndrome) high titres of IgG autoantibodies to U1snRNP-specific proteins are found. The isolated occurrence of these autoantibodies is highly associated with the HLA-DR4 haplotype. snRNP-specific T cells are supposed to be involved in this autoantibody production. To address this question we cultured mononuclear cells from MCTD patients and healthy donors with a highly purified UsnRNP preparation from HeLa cells using bulk or limiting dilution cultures. Secondary responses to snRNP were detected only rarely with T cell lines from two patients and two controls, and turned out to be unstable during further expansion. One T cell line derived from a healthy individual retained its snRNP reactivity upon limiting dilution cloning and could be characterized in detail. The CD4+ T cell clone recognized native snRNP particles presented by monocytes in an HLA-DR4 (B1*0401)-restricted manner. Separation of the protein and RNA moieties of snRNP particles revealed that the T cell clone responded specifically to the protein fraction, but not to RNA and diverse control antigens. Sequencing of the T cell receptor alpha and beta chain cDNAs revealed that the clone used the V alpha 14.2 and V beta 14 elements. Upon antigen-specific and mitogenic stimulation the T cell clone showed a Th1-specific cytokine pattern, and did not provide helper activity for in vitro immunoglobulin production. This study demonstrate the presence of self-reactive snRNP-specific T cells in a healthy donor. The T cell clone may not represent a helper T cell for the formation of U1snRNP-specific autoantibodies.

Abstract
The relationship of heat shock proteins and rheumatoid arthritis as well as the relevance of autoreactivity in this disease is unclear. T cells of six individuals (four expressing the DRB1*0401 allele, one harboring DRB1*0404 and one the DRB1*0407 allele) were cloned in the presence of 65kD mycobacterial heat shock protein (HSP60) in order to determine T cell receptors (TcR) used and the MHC class II restriction patterns of potentially relevant T cell clones (TcC). All TcC obtained were not specific for HSP60, but six TcC of one donor (HLA-DR4/HLA-DR5) were responsive towards autologous antigen-presenting cells. One TcC displayed authentic autoreactivity whereas five TcC reacted specifically to serum proteins. The amino acids (aa) of the MHC molecule, crucial for immune recognition were mapped to aa #71 or #86 of either maternal or paternal origin. The strictly autoreactive TcC did not recognize transfected L cells implicating specificity for self-peptides not presented by L cells or the involvement of adhesion molecules. Correlations between autoreactivity and TcR V(D)J sequences or N nucleotides of various "autoreactive" TcC were not evident.

Abstract
Synovial T lymphocytes seem to contribute to the pathogenesis of rheumatoid arthritis (RA). Since very little is known about the structural heterogeneity of their T cell antigen receptors (TcR), we analyzed TcR alpha chain mRNA of synovial fluid T cells from two RA patients. TcR alpha chain cDNA was amplified by the polymerase chain reaction with single-sided specificity for the alpha chain constant (C alpha) gene segment, and the nucleotide sequences of 51 functionally rearranged cDNA clones were determined. Twenty different V alpha genes and 26 different J alpha gene segments were utilized in these cDNA clones. Three of the V alpha gene segments which are frequently (8%-17% total) expressed in synovial fluid T cells have rarely been found in the TcR repertoire of peripheral blood T cells from healthy individuals. The T cell responses in the rheumatic synovia analyzed here are not oligoclonal, but the usage of TcR V alpha genes is biased.

Abstract
CD 4+ T cell lines responding specifically to Mycoplasma (M.) arthritidis were established from spleen and lymph nodes of a Lewis rat infected with M. arthritidis. The T cell response to M. arthritidis was MHC class II-restricted. M. arthritidis-reactive T cell lines also responded to syngeneic chondrocytes suggesting that M. arthritidis and chondrocytes may share a common antigenic structure. The T cell lines reacting with chondrocytes may play an important role in the chronic stage of the M. arthritidis-induced arthritis of rats by maintaining immune reactions initiated by M. arthritidis antigens and originally established to eliminate the mycoplasmas. These autoimmune reactions could perpetuate after disappearance of the mycoplasmas and possibly last for the entire lifetime.

Abstract
An alloreactive proliferative T-cell clone, 6065 WS, was obtained in an intrafamilial cell combination where the stimulator was a homozygous DRw11, DRw52, DQw3 son and the responder his haploidentical mother. Proliferation assays on eight local DRw11 families, 75 homozygous B-cell lines (Tenth Histocompatibility Workshop panel) and blocking assays with monoclonal antibodies showed that clone 6065 WS recognizes an epitope on the DRw11 beta 1 chain. Comparison of the reactivity of clone 6065 WS with cells expressing the three known DRw11 beta 1 amino acid sequences identified two unique amino acids at positions 71 and 86 which contribute to determining the specific recognition by the T-cell clone 6065 WS. Our data suggest that one or both of these amino acids can either be directly involved in the recognition by the T-cell receptor or responsible for critical conformation of the determinants on the DR molecule. Alternatively, they could affect recognition of a self peptide bound to the major histocompatibility complex class II molecule.

Abstract
A limiting dilution system was established in order to estimate frequencies of interleukin-2 (IL-2)-responsive, autoreactive and alloreactive T cells in samples of peripheral blood (PBL) and synovial fluid lymphocytes (SFL), from patients with rheumatoid arthritis (RA) and lyme disease, as well as from healthy donors and a patient with osteoarthrosis. The frequencies of IL-2-dependent T-cell colony formation were significantly higher in patients with RA and lyme disease (median: 1/287) as compared to controls (median: 1/1,313) indicating a preactivation of T cells in these patients in vivo. Autoreactivity was measured by the proliferative response of T-cell lines to autologous irradiated PBL as stimulating cells. The frequencies of autoreactive T cells in blood were significantly higher in patients (median: 1/2,615) as compared to controls (median: 1/19,607). There was no significant difference in autoreactive T-cell frequencies between the patients' SFL (median: 1/3,185) and PBL (median: 1/2,615). In every case the frequency of alloreactive T cells exceeded the frequency of autoreactive T cells. Most autoreactive T-cell lines were also alloreactive and were shown to be MHC Class II-restricted. There is evidence of a down regulation of autoreactive T cells by suppressor cells in peripheral blood in two cases with elevated autoreactive T-cell frequencies (one RA patient and one control patient suffering from a viral infection). In contrast, no suppression of autoreactive T cells was observed in the RA patients' SFL or in PBL and SFL from patients with lyme disease. These results suggest that the chronic inflammation observed in RA and lyme disease may be supported by an elevated number of autoreactive T cells in the absence of suppressive mechanisms.
