Abstract
While the etiology of multiple sclerosis (MS) remains unclear, research from the clinic and preclinical models identified the essential role of inflammation and demyelination in the pathogenesis of MS. Current treatments focused on anti-inflammatory processes are effective against acute episodes and relapsing-remitting MS, but patients still move on to develop secondary progressive MS. MS progression is associated with activation of microglia and astrocytes, and importantly, metabolic dysfunction leading to neuronal death. Neuronal death also contributes to chronic neuropathic pain. Metabolic support of neurons by glia may play central roles in preventing progression of MS and chronic neuropathic pain. Here, we review mechanisms of metabolic cooperation between glia and neurons and outline future perspectives exploring metabolic support of neurons by glia.

Abstract
T cells and B cells are crucial in the initiation and maintenance of multiple sclerosis (MS), and the activation of these cells is believed to be mediated through specific recognition of antigens by the T‐ and B‐cell receptors. The antigen receptors are highly polymorphic due to recombination (T‐ and B‐cell receptors) and mutation (B‐cell receptors) of the encoding genes, which can therefore be used as fingerprints to track individual T‐ and B‐cell clones. Such studies can shed light on mechanisms driving the immune responses and provide new insights into the pathogenesis. Here, we summarize studies that have explored the T‐ and B‐cell receptor repertoires using earlier methodological approaches, and we focus on how high‐throughput sequencing has provided new knowledge by surveying the immune repertoires in MS in even greater detail and with unprecedented depth.

Abstract
B lymphocytes play a pivotal role in multiple sclerosis pathology, possibly via both antibody-dependent and -independent pathways. Intrathecal immunoglobulin G in multiple sclerosis is produced by clonally expanded B-cell populations. Recent studies indicate that the complementarity determining regions of immunoglobulins specific for certain antigens are frequently shared between different individuals. In this study, our main objective was to identify specific proteomic profiles of mutated complementarity determining regions of immunoglobulin G present in multiple sclerosis patients but absent in healthy controls. To achieve this objective, we purified immunoglobulin G from the cerebrospinal fluid of 29 multiple sclerosis patients and 30 healthy controls and separated the corresponding heavy and light chains via SDS-PAGE. Subsequently, bands were excised, trypsinized, and measured with high-resolution mass spectrometry. We sequenced 841 heavy and 771 light chain variable region peptides. We observed 24 heavy and 26 light chain complementarity determining regions that were solely present in a number of multiple sclerosis patients. Using stringent criteria for the identification of common peptides, we found five complementarity determining regions shared in three or more patients and not in controls. Interestingly, one complementarity determining region with a single mutation was found in six patients. Additionally, one other patient carrying a similar complementarity determining region with another mutation was observed. In addition, we found a skew in the κ-to-λ ratio and in the usage of certain variable heavy regions that was previously observed at the transcriptome level. At the protein level, cerebrospinal fluid immunoglobulin G shares common characteristics in the antigen binding region among different multiple sclerosis patients. The indication of a shared fingerprint may indicate common antigens for B-cell activation.

Abstract
Multiple sclerosis (MS) is a chronic inflammatory disease of the CNS with presumed autoimmune origin. Pathogenic autoimmune responses in MS are thought to be the result of a breakdown of self tolerance. Several mechanisms account for the natural state of immunological tolerance to self antigens, including clonal deletion of self-reactive T cells in the thymus. However, autoimmune T cells are also part of the normal T-cell repertoire, supporting the existence of peripheral regulatory mechanisms that keep these potentially pathogenic T cells under control. One such mechanism involves active suppression by regulatory T cells. It has been indicated that regulatory T cells do not function properly in autoimmune disease. Immunization with attenuated autoreactive T cells, T-cell vaccination, may enhance or restore the regulatory immune networks to specifically suppress autoreactive T cells, as shown in experimental autoimmune encephalomyelitis, an animal model for MS. In the past decade, T-cell vaccination has been tested for MS in several clinical trials. This review summarizes these clinical trials and updates our current knowledge on the induction of regulatory immune networks by T cell vaccination.

Abstract
We developed a method for selectively propagating disease-related autoreactive T-cell lines (auTCLs) based on their increased resistance to apoptosis. The generated auTCLs homogeneously co-express CD45RO and CD49a, adhere strongly to extracellular matrix proteins and express high interleukin-17 (IL-17) messenger RNA levels, resembling a T-cell subset proposed to transmigrate into tissues and induce systemic and local inflammation in rheumatoid arthritis. The combinations of T-cell oligoclones that comprise probable multiple sclerosis (pMS) disease-related lines use a unique portfolio of T-cell receptor beta-chain variable allele (BV genes) combinations forming 'disease-specific cluster patterns'. The auTCL derived from different patients and from different myelin epitopes display striking similarities in BV gene allele clusters and are derived primarily from a disease-prone hotspot residing in the BV gene locus between Vbeta6 and Vbeta9. Conversely, healthy subject TCLs use different BV gene allele sets, forming 'healthy responder usage formats'. These formats were absent from the pMS patient V-beta gene allele combinations evaluated in this study. Hierarchical clustering of the BV gene combinations, distinguish three pMS auTCL groups, implying existence of up to three disease-related immune response patterns. These subgroup patterns may reflect different disease subclasses or alternatively they may suggest immune reactivity to different aetiological agents. Analyses of clonal-clustering patterns may potentially aid in subclassification of MS or in characterizing aetiological agents of this disease.

Abstract
During open heart surgery in infants the thymus was usually removed, partly or completely. Our previous studies on 16 such children indicated reduced T-cell output later in life with signs of extrathymic maturation of the T cells, but no reduction in T regulatory cells (CD4+CD25+). The diversity of the T-cell repertoire in these children was examined to test if the extrathymic microenvironment could alter Vbeta usage. The expression of Foxp3 and CD127 in CD4+CD25(high) T cells was measured in order to determine whether the T regulatory cells had the phenotype of natural T regulatory cells. There was a wide distribution of Vbeta usage in both study and control groups. Significant variability was found in Vbeta usage for CD4+ and CD8+ T cells when the distribution of the percentage of T cells expressing each Vbeta family was analysed between individuals within each group (P < 0.001; Kruskal-Wallis). Significant difference was also found in average usage of Vbeta2, Vbeta5.1 and Vbeta14 chains within CD4+ T cells and Vbeta2, Vbeta8 and Vbeta21.3 chains within CD8+ cells between the groups (P < 0.05; Student's t-test). There was no difference between the two groups with regard to the proportion of CD4+CD25(high) T cells and no difference in the average expression of Foxp3 or CD127 within the CD4+CD25(high) population. Our data provide evidence that cardiothoracic surgery in infants and total or partial thymectomy alters Vbeta usage, suggesting more limited selection in such children than in the control group. The frequency of natural T regulatory cells seems to be unimpaired.

Abstract
BACKGROUND & AIMS Biliary atresia is an inflammatory, fibrosclerosing neonatal cholangiopathy, characterized by a periductal infiltrate composed of CD4(+) and CD8(+) T cells. The pathogenesis of this disease has been proposed to involve a virus-induced, subsequent autoreactive T cell-mediated bile duct injury. Antigen-specific T-cell immunity involves clonal expansion of T cells expressing similar T-cell receptor (TCR) variable regions of the beta-chain (Vbeta). We hypothesized that the T cells in biliary atresia tissue expressed related TCRs, suggesting that the expansion was in direct response to antigenic stimulation. METHODS The TCR Vbeta repertoire of T cells from the liver, extrahepatic bile duct remnants, and peripheral blood of biliary atresia and other cholestatic disease controls were characterized by fluorescent-activated cell sorter analysis, and TCR junctional region nucleotide sequencing was performed on expanded TCR Vbeta regions to confirm oligoclonality. RESULTS FACS analysis revealed Vbeta subset expansions of CD4(+) and CD8(+) T cells from the liver or bile duct remnant in all patients with biliary atresia and only 1 control. The CD4(+) TCR expansions were limited to Vbeta3, -5, -9, and -12 T-cell subsets and the CD8(+) TCR Vbeta expansions were predominantly Vbeta20. Each Vbeta subset expansion was composed of oligoclonal populations of T cells. CONCLUSIONS Biliary atresia is associated with oligoclonal expansions of CD4(+) and CD8(+) T cells within liver and extrahepatic bile duct remnant tissues, indicating the presence of activated T cells reacting to specific antigenic stimulation. Future studies entail identifying the specific antigen(s) responsible for T-cell activation and bile duct injury.

Abstract
Both genetic background and environmental factors, very probably viruses, appear to play a role in the etiology of multiple sclerosis (MS). Lessons from viral experimental models suggest that many different viruses may trigger inflammatory demyelinating diseases resembling MS. Theiler's virus, a picornavirus, induces in susceptible strains of mice early acute disease resembling encephalomyelitis followed by late chronic demyelinating disease, which is one of the best, if not the best, animal model for MS. During early acute disease the virus replicates in gray matter of the central nervous system but is eliminated to very low titers 2 weeks postinfection. Late chronic demyelinating disease becomes clinically apparent approximately 2 weeks later and is characterized by extensive demyelinating lesions and mononuclear cell infiltrates, progressive spinal cord atrophy, and axonal loss. Myelin damage is immunologically mediated, but it is not clear whether it is due to molecular mimicry or epitope spreading. Cytokines, nitric oxide/reactive nitrogen species, and costimulatory molecules are involved in the pathogenesis of both diseases. Close similarities between Theiler's virus-induced demyelinating disease in mice and MS in humans, include the following: major histocompatibility complex-dependent susceptibility; substantial similarities in neuropathology, including axonal damage and remyelination; and paucity of T-cell apoptosis in demyelinating disease. Both diseases are immunologically mediated. These common features emphasize the close similarities of Theiler's virus-induced demyelinating disease in mice and MS in humans.

Abstract
Multiple sclerosis (MS) is a chronic inflammatory disease of the central nervous system (CNS). Significant progress has been made in our understanding of the etiology of MS. MS is widely believed to be an autoimmune disease that results from aberrant immune responses to CNS antigens. T cells are considered to be crucial in orchestrating an immunopathological cascade that results in damage to the myelin sheath. This review summarizes the currently available data supporting the idea that myelin reactive T cells are actively involved in the immunopathogenesis of MS. Some of the therapeutic strategies for MS are discussed with a focus on immunotherapies that aim to specifically target the myelin reactive T cells.

Abstract
To understand the short-term dynamics of the circulating T cell receptor V beta (TCRBV) repertoire in relapsing-remitting multiple sclerosis (MS), we monitored the TCRBV profiles of untreated MS patients and healthy controls. Expansions of TCRBV genes in MS patients were significantly more frequent than in controls (P<0.001), were predominantly oligoclonal (80%) and were significantly correlated with immune responses to myelin basic protein (MBP) (P<0.02) and with inflammatory disease activity detected by magnetic resonance imaging (MRI) (P<0.05). Autoreactive T cell responses against myelin antigens may be implicated in perturbations of TCR repertoire in untreated MS patients, detectable even in the absence of clinically evident manifestations.

Abstract
Multiple sclerosis is a chronic inflammatory demyelinating disease of the CNS. Although the aetiology of multiple sclerosis is still unknown, it is widely believed that T cells play a central role in its pathogenesis. To identify and characterize disease-relevant T cells, we analysed CD4+ and CD8+ T cells freshly isolated from the CSF and peripheral blood of 36 multiple sclerosis patients for their T-cell receptor variable beta (TCRBV) chain repertoire. In most patients, we found significant overexpression of individual TCRBV chains on CD8+ T cells from CSF compared with peripheral blood. In contrast, only a few multiple sclerosis patients showed differences between the two compartments in TCRBV expression on CD4+ T cells. The overexpression of specific TCRBV chains on CD8+ T cells was found to be stable over several months in selected patients and involved mainly T cells with a memory phenotype. In two patients studied, individual TCRBV chain overexpression was found to be caused by the expansion of T cell populations with identical or highly similar rearranged T-cell receptor beta- and alpha-chain sequences, which were not found among peripheral blood CD8+ T cells. Our findings demonstrate selective enrichment of memory CD8+ T cells in the CSF of multiple sclerosis patients, suggesting a role for these CD8+ T cells in the pathogenesis of multiple sclerosis. Our study provides a basis for future trials to identify disease-associated antigens and disease pathogenesis in multiple sclerosis.

Abstract
We have investigated the clonality of beta-chain T-cell receptor (TCR) transcripts from the cerebrospinal fluid (CSF) and peripheral blood from a 7-year old child who developed a multiphasic disseminated encephalomyelitis following an infection with hepatitis A virus. We amplified beta-chain TCR transcripts by nonpalindromic adaptor (NPA)-PCR-Vbeta-specific PCR. TCR transcripts from only five Vbeta families (Vbeta13, Vbeta3, Vbeta17, Vbeta8, and Vbeta20) were detected in CSF. The amplified products were combined, cloned, and sequenced. Sequence analysis revealed in the CSF substantial proportions of identical beta-chain of TCR transcripts, demonstrating oligoclonal populations of T cells. Seventeen of 35 (48%) transcripts were 100% identical, demonstrating a major Vbeta13.3 Dbeta2.1 Jbeta1.3 clonal expansion. Six of 35 (17%) transcripts were also 100% identical, revealing a second Vbeta13 clonal expansion (Vbeta13.1 Dbeta2.1 Jbeta1.2). Clonal expansions were also found within the Vbeta3 family (transcript Vbeta3.1 Dbeta2.1 Jbeta1.5 accounted for 5 of 35 transcripts [14%]) and within the Vbeta20 family (transcript Vbeta20.1 Dbeta1.1 Jbeta2.4 accounted for 3 of 35 transcripts [8%]). These results demonstrate the presence of T-cell oligoclonal expansions in the CSF of this patient following infection with hepatitis A virus. Analysis of the CDR3 motifs revealed that two of the clonally expanded T-cell clones exhibited substantial homology to myelin basic protein-reactive T-cell clones. In contrast, all Vbeta TCR families were expressed in peripheral blood lymphocytes. Oligoclonal expansions of T cells were not detected in the peripheral blood of this patient. It remains to be determined whether these clonally expanded T cells are specific for hepatitis A viral antigen(s) or host central nervous system antigen(s) and whether molecular mimicry between hepatitis A viral protein and a host protein is responsible for demyelinating disease in this patient.

Abstract
OBJECTIVE To evaluate the T cell receptor beta chain variable region (TCRBV) gene usage ex vivo in CSF cells and peripheral blood mononuclear cells (PBMCs) collected from patients with autoimmune and inflammatory diseases of the nervous system. METHODS A novel sensitive seminestedpolymerase chain reaction coupled with heteroduplex analysis was developed. RESULTS Under these experimental conditions, the minimal number of cells required for the analysis of the whole T cell repertoire was established at 2.5x10(4)-sufficient to evaluate most of the samples collected during diagnostic lumbar punctures. In the 21 patients examined, restrictions in TCRBV gene family usage were not seen. However, using heteroduplex analysis, oligoclonal T cell expansions were found in the CSF of 13 patients and monoclonal expansions in five patients. The T cell abnormalities found did not correlate with intrathecal IgG production or with any clinical variable considered. CONCLUSION T cell clonal expansions, useful for further characterisation of pathogenetic T cells, can be found during the course of nervous system inflammations, but this abnormality is probably not disease specific.

Abstract
Clonal composition and T cell receptor (TCR) repertoire of CD4(+) and CD8(+) T cells infiltrating actively demyelinating multiple sclerosis (MS) lesions were determined with unprecedented resolution at the level of single cells. Individual CD4(+) or CD8(+) T cells were isolated from frozen sections of lesional tissue by micromanipulation and subjected to single target amplification of TCR-beta gene rearrangements. This strategy allows the assignment of a TCR variable region (V region) sequence to the particular T cell from which it was amplified. Sequence analysis revealed that in both cases investigated, the majority of CD8(+) T cells belonged to few clones. One of these clones accounted for 35% of CD8(+) T cells in case 1. V region sequence comparison revealed signs of selection for common peptide specificities for some of the CD8(+) T cells in case 1. In both cases, the CD4(+) T cell population was more heterogeneous. Most CD4(+) and CD8(+) clones were represented in perivascular infiltrates as well as among parenchymal T cells. In case 2, two of the CD8(+) clones identified in brain tissue were also detected in peripheral blood. Investigation of the antigenic specificities of expanded clones may help to elucidate their functional properties.

Abstract
OBJECTIVES There have been many studies reporting restricted patterns of T cell receptor usage in established multiple sclerosis and these have led to clinical trials of immunomodulation directed at deleting clonal T cell populations. The present study aims to test the hypothesis that highly restricted T cell populations are also present in the CSF in the earliest clinical stages of acute demyelinating disease of the CNS. METHODS T cell receptor Vbeta (TCRBV) gene expression was studied in CSF and blood in nine patients with acute optic neuritis within 7 days of onset of symptoms, six patients with an acute relapse of multiple sclerosis, and 13 control subjects. RNA was extracted and cDNA synthesised from unstimulated CSF and blood lymphocytes, and TCRBV gene segments were amplified from the cDNA by polymerase chain reaction (PCR) using 21 family specific primers. PCR products were separated by polyacrylamide gel electrophoresis and detected via a labelled oligonucleotide probe. A semiquantitative analysis of band intensity was performed by laser densitometry. RESULTS TCRBV mRNA was detected in the CSF of eight of nine patients with optic neuritis, six of six patients with multiple sclerosis, and five of 13 controls, and was closely correlated with the presence of oligoclonal IgG. Usage of a single TCRBV family was demonstrated in two of nine patients with optic neuritis and two of six patients with multiple sclerosis. The number of TCRBV families expressed in the other patients ranged between 5 and 15 (optic neuritis) and 4 and 17 (multiple sclerosis). CONCLUSIONS There is a relative lack of restriction of TCRBV usage by CSF lymphocytes in the very earliest stages (<7 days) of acute optic neuritis. This may imply either that multiple sclerosis is not a monoclonal disease even at onset, or that the autoimmune response has widened before the disease becomes clinically evident. This may have important consequences for the design of immune therapies in multiple sclerosis. Further studies are required to determine whether the CSF T cell repertoire at presentation has prognostic importance. Longitudinal studies are required to follow the CSF T cell repertoire from the time of presentation and to determine whether it may have prognostic significance.

Abstract
Multiple sclerosis is an inflammatory demyelinating CNS disease of putatively autoimmune origin. Novel models of experimental autoimmune encephalomyelitis (EAE) have demonstrated that T cells specific for various myelin and even nonmyelin proteins are potentially encephalitogenic. The encephalitogenic T cell response directed against different CNS antigens not only determines the lesional topography of CNS inflammation but also the composition of the inflammatory infiltrates. The heterogeneity of the lesional distribution seen in EAE might therefore be useful for the understanding of the various clinical subtypes seen in MS. In this review the possible candidate autoantigens in MS are discussed with special regard to the human T cell and B cell responses against various myelin and nonmyelin proteins.

Abstract
OBJECTIVE Restricted T cell receptor (TCR) gene usage has been demonstrated in animal models of autoimmune disease and has resulted in the successful use of TCR peptide therapy in animal studies. This clinical trial was undertaken to determine the safety and efficacy of a combination of Vbeta3, Vbeta14, and Vbeta17 TCR peptides in Freund's incomplete adjuvant (IFA) in patients with rheumatoid arthritis (RA). METHODS A double-blind, placebo-controlled, multicenter, phase II clinical trial was undertaken using IR501 therapeutic vaccine, which consists of a combination of 3 peptides derived from TCRs (Vbeta3, Vbeta14, and Vbeta17) in IFA. A total of 99 patients with active RA received either 90 microg (n = 31) or 300 microg (n = 35) of IR501 or IFA alone (n = 33) as a control. The study medication and placebo were administered as a single intramuscular injection (1 ml) at weeks 0, 4, 8, and 20. RESULTS Treatment with IR501 was safe and well tolerated. None of the patients discontinued the trial because of treatment-related adverse events. Efficacy was measured according to the American College of Rheumatology 20% improvement criteria. Using these criteria, patients in both IR501 dosage groups showed improvement in disease activity. In the most conservative analysis used to evaluate efficacy, an intent-to-treat analysis including all patients who enrolled, the 90-microg dosage group showed a statistically significant improvement compared with control patients at the 20-week time point after the third injection. Trends toward improvement were shown in both the 90-microg and the 300-microg dosage groups at week 24 after the fourth injection. CONCLUSION IR501 therapeutic vaccine therapy was safe and well tolerated, immunogenic, and demonstrated clinical improvement in RA patients. Additional clinical trials are planned to confirm and extend these observations.

Abstract
In a small group of subjects we had identified persistent expansions (range 6-72%) of CD4(+)CD8(+) double-positive (DP) peripheral blood (PB) cells which express the CD8 alpha/alpha homodimer. Here, DP cells present in a larger cohort were further investigated and found by FACS analysis to express a single or a dominant TCRBV family. In these subjects, with a mean age of about 64 years, expansions of CD4(+) cells with the same TCRBV family specificity as in the respective DP cells also were consistently detected. TCR heterogeneity of the dominant TCRBV family was specifically evaluated: The amplified CDR3 region was cloned and found to consist of one single or two largely dominant sequence patterns. Furthermore, cloning of the CDR3 region from FACS-sorted DP, CD4(+), or CD8(+) cells indicates that both DP and CD4(+), but not CD8(+) cells, isolated from the same individual possess a striking identity of the CDR3 regions. As indicated by FACS analysis, the clonally expanded cells occur in the CD4(+)CD28(-) cells. Taken together, these results suggest that expanded CD4(+)CD28(-) cells might also acquire CD8 alpha/alpha expression and become DP and imply that CD4 clonality is a more frequent phenomenon than previously suspected. In conclusion, the persistent expansions described in this report represent a novel group of age-related benign clonal expansions of still undefined significance of a rare CD28(-) T cell subset.

Abstract
In several human T-cell-mediated autoimmune diseases and animal models of such illnesses, T-cell receptors (TCR) specific for antigens that initiate or perpetuate the disease share a limited number of variable region determinants. Vaccinations with peptides derived from over-represented TCRs are effective treatment for some of these disorders. RA is a chronic inflammatory disease in which there is prominent T-cell infiltration in the synovial lining layer. TCR V beta 3, V beta 14, and V beta 17 have been found to be over-represented among IL-2 receptor-positive T-cells from patients with RA. A phase II clinical trial in RA, using a combination of three peptides derived from V beta 3, V beta 14, and V beta 17, has yielded promising results. Larger clinical efficacy and safety studies must be performed to determine if TCR peptide vaccination will become a viable treatment alternative for patients with RA.

Abstract
Until recently, the search for the 'culprit' autoantigen towards which deleterious autoimmunity is directed in multiple sclerosis (MS) centered mostly on myelin basic protein (MBP) and proteolipid (PLP), the two most abundant protein components of central nervous system (CNS) myelin, the target tissue for the autoimmune attack in MS. Although such research has yielded important data, furthering our understanding of the disease and opening avenues for possible immune-specific therapeutic approaches, attempts to unequivocally associate MS with MBP or PLP as primary target antigens in the disease have not been successful. This has led in recent years to a new perspective in MS research, whereby different CNS antigens are being investigated for their possible role in the initiation or progression of MS. Interesting studies in laboratory animals show that T-cells directed against certain non-myelin-specific CNS antigens are able to cause inflammation of the CNS, albeit without expression of clinical disease. However, reactivity to these antigens by MS T-cells has not been demonstrated. Conversely, reactivity by MS T-cells to non-myelin-specific antigens such as heat shock proteins, could be observed, but the pathogenic potential of such reactivity has not been corroborated with the encephalitogenicity of the antigen. More relevant to MS pathogenesis may be, as we outlined in this review, the autoimmune reactivity directed against minor myelin proteins, in particular the CNS-specific myelin oligodendrocyte glycoprotein (MOG). Here, we review the current knowledge gathered on T-cell reactivity to possible target antigens in MS in the context of their encephalitogenic potential, and underline the facets which make MOG a highly relevant contender as primary target antigen in MS, albeit not necessarily the only one.

Abstract
To better characterize the cellular immune response taking place in the MS central nervous system, we investigated the blood and CSF T cell receptor (TCR) V beta 5 and V beta 17 repertoire in HLA-typed patients with recently diagnosed MS or other neurological diseases (OND). Using a RT-PCR based technique, we analysed directly ex vivo the CDR3 size of TCR beta chains utilizing V beta 5 (eight patients with MS and one with OND) or V beta 17 (eight patients with MS and six with OND) gene segments on paired blood-CSF samples. Globally, the analysis of V beta 5-J beta and V beta 17-J beta repertoire showed a less diverse pattern in the CSF samples than in the corresponding peripheral blood lymphocytes both in MS and in OND patients. However, we did not detect any recurrent clonal expansion within the V beta 5+ T cells in MS patients, underlining the potential limits of V beta 5-based immunotherapy in MS. We found an expanded T cell population using the same V beta 17-J beta 1.6 combination with identical CDR3 length in the CSF of three MS patients and none of the control patients. These results suggest selective expansion of T cells expressing this segment gene in the MS central nervous system.

Abstract
A new method for the detection of all known possible rearrangements at the variable (V), diversity (D), and joining (J) segments of the T-cell receptor beta chain (TcR beta) gene in tissue DNA extracts is described that involves two polymerase chain reactions (PCRs). The first PCR round (screening PCR) allowed the identification of the J beta segment involved in a clonal rearrangement. A J beta-primer was used for the second PCR (J beta-specific PCR), recognizing the J beta segment identified in the screening PCR in combination with a consensus V beta primer. This PCR generated prominent and short amplificates suitable for direct sequence analysis because of their low background. Using this approach, clonal TcR beta gene rearrangements were able to be demonstrated in all T-cell lines (n = 7) and in all peripheral T-cell lymphomas (n = 33) analyzed. No clonal TcR beta gene rearrangements were found in any of the normal tissues studied nor in any B-cell non-Hodgkin lymphomas. This method is applicable to DNA from fresh frozen tissues, and, after the TcR beta rearrangement of a patient's malignant T-cell clone has been identified by the screening PCR, DNA can also be detected in follow-up formalin-fixed paraffin-embedded samples by the J beta-specific PCR with high sensitivity and specificity.

Abstract
This study was designed to examine the immunogenetic background predisposing to multiple sclerosis (MS). Three hundred fifty-eight clinically well-characterized MS patients from Germany were investigated and compared to 395 healthy control subjects. Each individual was genotyped for 22 polymorphic markers located within or close to immunorelevant candidate genes including HLA-DRB1*, T-cell receptor (TCR), cell interaction molecules, cytokines, and cytokine receptor genes. Altogether, approximately 17,000 genetic analyses were performed. Patients were grouped according to the course of MS-relapsing-remitting or chronic progressive. Most of the genetic markers were not associated with increased risk or their exact contribution was not clear (e.g., tumor necrosis factor). The relative risks for HLA-DRB1*15+ and DRB1*03+ individuals were 3.64 and 1.42, respectively. In both groups of patients, certain TCRB gene polymorphisms were risk factors. In DRB1*03+ individuals the relative risk was increased (> 22) when a specific TCRBV6S3 allele was also inherited. Furthermore, distinct linkage disequilibria of TCRBV6S1/TCRBV6S3 elements in patients and control subjects strongly suggested an additional risk factor in the TCRBV region for DRB1*15+ individuals. These findings are discussed with respect to the pathogenesis and rational approaches to the therapy of MS.

Abstract
We set out to determine whether the T cell receptor (TCR) V beta gene usage in acute inflammatory demyelinating polyradiculoneuropathy (AIDP) is restricted. We separated activated from non-activated peripheral blood T cells with anti-IL2 receptor (anti-CD25) antibody-labelled magnetic beads from four AIDP patients and four normal control (NC) subjects. The TCR V beta gene usage of circulating activated and non-activated T cells was heterogeneous in all the patients and controls, but the activated T cells of all four of the AIDP patients showed a more limited usage of V beta genes and enhanced V beta 15 usage, as compared to the non-activated T cells. This was not seen in the healthy controls. The activated and non-activated T cells from a patient with acute motor and sensory axonal neuropathy (AMSAN) showed a similar V beta gene usage to that of the controls. From a further patient with AIDP, we studied the V beta gene usage of short-term T cell lines reactive to the peripheral nerve myelin proteins P2, P0 and the P0 peptide amino acid sequence 194-208. The V beta gene usage of the lines was heterogeneous, with enhanced usage of V beta 15 in the cell line responsive to the Pzero peptide. We conclude that T cells activated during the immune response associated with AIDP preferentially used V beta 15, which may indicate a restricted response to a common antigen, or a role for an as yet undefined superantigen in the pathogenesis of AIDP.

Abstract
Activated T-cells are believed to play a critical role in the pathogenesis of autoimmune disease. In experimental allergic encephalomyelitis (EAE), an animal model resembling human multiple sclerosis (MS), there is evidence that T cells reactive to myelin basic protein mediate an inflammatory response within the central nervous system leading to demyelination. Furthermore, encephalitogenic T cells express TCR with highly restricted V gene usage and consequently specific forms of immunotherapy directed against V gene products have been successful in preventing and treating EAE. These findings prompted studies into the analysis of TCR repertoire expression in human autoimmune diseases in an attempt to identify the TCR usage of autoreactive and potentially pathogenic T cells. However, this has proved difficult as the autoantigens that drive the T cell response in most human autoimmune disorders are unknown. This review examines the data that have accumulated over the past few years on TCR usage in human autoimmune diseases and is focused largely on rheumatoid arthritis and MS.

Abstract
We have used two approaches to isolate TCR sequences that are unique to patients with multiple sclerosis. One strategy was to sequence TCR gene rearrangements directly from MS lesions. The second strategy utilized T-cell clones with a selectable mutation that are found only in MS patients. The selection of T-cell clones with mutations in the hypoxanthine guanine phosphoribosyltransferase (hprt) gene was used to isolate T-cells reactive to myelin basic protein (MBP) in patients with multiple sclerosis (MS). These T-cell clones are activated in vivo, and are not found in healthy individuals. The third complementarity determining regions (CDR3) of the T-cell receptor (TCR) alpha and beta chains are the putative contact sites for peptide fragments of MBP bound in the groove of the HLA molecule. The TCR V gene usage and CDR3s of these MBP-reactive hprt- T-cell clones are homologous to TCRs from other T-cells relevant to MS, including T-cells causing experimental allergic encephalomyelitis (EAE) and T-cells found in brain lesions and in the cerebrospinal fluid (CSF) of MS patients. In vivo activated MBP-reactive T-cells in MS patients may be critical in the pathogenesis of MS.

Med. 1989, 169: 27; Chluba, J., Steeg, C., Becker, A., Wekerle, H. and Epplen, J. T., Eur. J. Immunol. 1989. 19: 279] and a quite diverse V beta composition of CD4 T cells causing experimental autoimmune encephalomyelitis (EAE) [Sun, D., Gold, P. D., Smith, L., Brostoff, S. and Coleclough, C., Eur. J. Immunol, 1992. 22: 591; Sun, D., Le, J. and Coleclough, C., Eur. J. Immunol. 1993. 23: 494] have been reported. Using a recently developed monoclonal antibody (mAb) specific for TCR V beta 8.2, we show that postnatal treatment effectively eliminates V beta 8.2-bearing cells and prevents MBP-induced EAE in the majority of Lewis rats. Moreover, treatment of adult Lewis rats with V beta 8.2-specific mAb as late as on day 12 after MBP immunization suppressed the development of neurological symptoms. Thus, V beta 8.2-bearing cells do play a decisive role in Lewis rat EAE, and suppression of the small (5%) V beta 8.2-expressing T cell subset provides an effective therapeutic strategy.

Abstract
Superantigens such as the staphylococcal enterotoxins can play an important role in exacerbation of autoimmune disorders such as experimental allergic encephalomyelitis (EAE) in mice. In fact, superantigens can reactivate EAE in PL/J mice that have been sensitized to rat myelin basic protein (MBP). The T-cell subset predominantly responsible for disease in PL/J mice bears the V beta 8+ T-cell antigen receptor (TCR). The question arises as to whether T cells bearing other V beta specificities are involved in induction or reactivation of EAE with superantigen. Thus, we have investigated the ability of a non-V beta 8-specific superantigen, staphylococcal enterotoxin A (SEA) (V beta specificities 1, 3, 10, 11, and 17), to induce EAE in PL/J mice that have been previously protected from disease by anergy and deletion of V beta 8+ T cells. PL/J mice were first pretreated with the V beta 8-specific superantigen staphylococcal enterotoxin B (SEB) and then immunized with MBP. These mice exhibited V beta 8-specific anergy and depletion and did not develop EAE, even when further treated with SEB. However, administration of SEA to these same mice induced an initial episode of EAE which was characterized by severe hindleg paralysis and accelerated onset of disease. In contrast to SEB pretreatment, PL/J mice pretreated with SEA did develop EAE when immunized with MBP, and after resolution of clinical signs of disease these mice were susceptible to relapse of EAE induced by SEB but not by SEA. Thus, superantigens can activate encephalitogenic MBP-specific non-V beta 8+ T cells to cause EAE in PL/J mice. These data suggest that superantigens can play a central role in autoimmune disorders and that they introduce a profound complexity to autoimmune diseases such as EAE, akin to the complexity seen in multiple sclerosis.

Abstract
The selection of T cell clones with mutations in the hypoxanthine guanine phosphoribosyltransferase (hprt) gene has been used to isolate T cells reactive to myelin basic protein (MBP) in patients with multiple sclerosis (MS). These T cell clones are activated in vivo, and are not found in healthy individuals. The third complementarity determining regions (CDR3) of the T cell receptor (TCR) alpha and beta chains are the putative contact sites for peptide fragments of MBP bound in the groove of the HLA molecule. The TCR V gene usage and CDR3s of these MBP-reactive hprt-T cell clones are homologous to TCRs from other T cells relevant to MS, including T cells causing experimental allergic encephalomyelitis (EAE) and T cells found in brain lesions and in the cerebrospinal fluid (CSF) of MS patients. In vivo activated MBP-reactive T cells in MS patients may be critical in the pathogenesis of MS.

Abstract
The pathogenesis of multiple sclerosis (MS) is thought to involve a T-cell-mediated autoimmune process. Experimental allergic encephalomyelitis (EAE), an animal model resembling MS, can be induced by immunization with myelin antigens such as myelin basic protein. The T-cell antigen receptor (TCR) usage in EAE is highly restricted in some strains of animals and experimental treatments targeting the TCR have been successful in EAE. Examination of the TCR beta-chain variable-region (V beta) usage of MBP-specific T-cell lines in MS patients has produced conflicting results. Our previous studies of TCR alpha-chain variable-region usage in monozygotic twins demonstrated a general skewing of the TCR repertoire in individuals with MS. This skewing became apparent only after stimulation with antigens; in peripheral blood lymphocyte preparations from individuals with MS V alpha 8-bearing T cells were preferentially selected by stimulation with myelin basic protein. In the present study we examined complementarity-determining region 3 of those V alpha 8-positive TCRs. Marked sequence heterogeneity was found in all individuals with severe MS. In contrast, restricted areas of complementarity-determining region 3 were found in healthy control individuals and in individuals with a mild form of MS. Sequences from tetanus toxoid-specific V alpha 8-positive T cells generated from the same individuals were relatively homogeneous within individuals regardless of disease activity and were distinct from the sequences of complementarity-determining region 3 in myelin basic protein-stimulated lines. These findings suggest that disease severity may be associated with increased heterogeneity of myelin antigen-specific T cells and could reflect an impaired ability of the immune system to down-regulate these anti-self responses.

Abstract
Equal numbers of CD4+ T cells recognizing myelin basic protein (MBP) and proteolipid protein (PLP) are found in the circulation of normal individuals and multiple sclerosis (MS) patients. We hypothesized that if myelin-reactive T cells are critical for the pathogenesis of MS, they would exist in a different state of activation as compared with myelin-reactive T cells cloned from the blood of normal individuals. This was investigated in a total of 62 subjects with definitive MS. While there were no differences in the frequencies of MBP- and PLP-reactive T cells after primary antigen stimulation, the frequency of MBP or PLP but not tetanus toxoid-reactive T cells generated after primary recombinant interleukin (rIL-2) stimulation was significantly higher in MS patients as compared with control individuals. Primary rIL-2-stimulated MBP-reactive T cell lines were CD4+ and recognized MBP epitopes 84-102 and 143-168 similar to MBP-reactive T cell lines generated with primary MBP stimulation. In the cerebrospinal fluid (CSF) of MS patients, MBP-reactive T cells generated with primary rIL-2 stimulation accounted for 7% of the IL-2-responsive cells, greater than 10-fold higher than paired blood samples, and these T cells also selectively recognized MBP peptides 84-102 and 143-168. In striking contrast, MBP-reactive T cells were not detected in CSF obtained from patients with other neurologic diseases. These results provide definitive in vitro evidence of an absolute difference in the activation state of myelin-reactive T cells in the central nervous system of patients with MS and provide evidence of a pathogenic role of autoreactive T cells in the disease.

Abstract
To determine whether T cells, like B cells, can become clonally expanded in normal individuals as a function of age, we compared the T cell V beta repertoire of cord blood to that of peripheral blood from normal donors over 65 yr of age. T cells from elderly subjects contained expanded subsets (greater than the mean+three standard deviations) of T cell receptor (TCR) V beta populations. These expanded subsets were observed primarily among CD8, but not CD4 cells, represented up to 37.5% of all CD8 cells, and were present in most elderly subjects. An expanded V beta 5.2/3 CD8 subset and a V beta 6.7a CD8 subset from separate donors were analyzed by reverse transcriptase-polymerase chain reaction, cloning and sequencing of the TCR beta chain VDJ junction. In both cases the expanded subsets were mono- or oligoclonal while control CD4 populations were polyclonal. Using two-color flow cytometry it was possible to identify the expanded V beta 6.7a subset as CD8+ CD28-CD11b+ cells. In three of five random old subjects similar expansions of V beta subsets were found specifically in the CD8+ CD28- subpopulation, an interesting subset of cytotoxic T lymphocytes, known to lack proliferative responses to TCR stimuli. It is common practice to use the demonstration of clonality as a diagnostic indicator for T cell lymphoma/leukemia. In view of the high frequency of expanded T clones of T cells in normal elderly subjects the diagnostic usefulness of this test should be reexamined.

Abstract
Synovial T cells play a crucial role in the pathogenesis of rheumatoid arthritis (RA) synovitis. We have quantitatively analyzed the T cell receptor (TcR) variable (V) region gene repertoire of freshly isolated synovial fluid (SF) T cells, comparing it with that of peripheral blood (PB) T cells in RA. The TcR V gene repertoire of PB and SF T cells in RA and osteoarthritis was heterogeneous. In contrast, V alpha 11 in SF was expressed to a greater degree in three of five RA patients, and increased levels of V beta 6, 1-3 were found in the SF of four of six RA, compared with paired PB. Of note, V beta 6, 1-3 was universally used in four RA patients with a disease duration of less than 10 years, irrespective of their HLA-DR types. This was in contrast to two other RA patients, suffering for more than 20 years, who showed different V alpha and V beta usages. beta-chain sequence analysis in RA patients with a preference for V beta 6, 1-3 has shown that a few clones dominated in SF, whereas polyclonality was observed in PB. These findings suggest oligoclonal expansion of T cells in response to specific antigen(s) in the SF of these patients with RA of relatively short duration. Concomitant use of two hydrophobic amino acids, leucine and valine in the D beta region was noticeable among the predominant SF clones. These two amino acids might directly contact a peptide specific for the induction of synovitis in RA patients. TcR-directed therapy may, therefore, be useful for the treatment of early RA synovitis.

Abstract
We utilized the polymerase chain reaction (PCR) to examine for preferential expression of T cell receptor (TcR) V beta s in T cells infiltrating the central nervous system (CNS) of mice infected with Theiler's virus. Infection of susceptible strains of mice with Theiler's virus results in demyelinating disease similar to multiple sclerosis. At 7 days following infection, no difference was observed in TcR V beta usage in lymphocytes infiltrating the CNS between resistant (B10.K) and susceptible (B10.Q or SJL/J) mice. In susceptible mice with prominent demyelination (day 45 and 238 following infection), no preferential expression of TcR V beta s was observed in the CNS. There is strong evidence that T cells play a major role in pathogenesis of TMEV-induced demyelination. There is increasing evidence using recombinant inbred strain mice with TcR V beta deletions that T cells expressing certain TcR V beta genes may be critical in the disease process. Yet, analysis of TcR V beta expression on T cells in CNS using PCR technology did not provide a way to dissect which antigen-specific T cells play a role in disease. These results confirm that during active demyelination specific as well as non-specific T cells are recruited to the CNS. Even though the pathogenesis of TMEV-induced disease may not be identical to that in multiple sclerosis, it is unlikely that similar approaches utilizing polymerase chain reaction will provide insights to the role of T cell receptors in the pathogenesis of multiple sclerosis.

Abstract
Multiple sclerosis (MS) is generally considered to be an autoimmune disorder with myelin as the target and with several unidentified viruses playing ancillary roles, possibly through molecular mimicry. Although this paradigm has led to important progress on potential mechanisms of myelin loss, neither a target antigen in myelin nor a triggering mechanism has yet been identified, leaving the etiology of MS still unknown. Animal models of viral demyelination and studies showing that JC virus (JCV), the polyomavirus which causes progressive multifocal leukoencephalopathy (PML), may be latent in some normal human brains suggest another possibility. A host immune response targeting proteins expressed at low levels from viral DNA latent in the central nervous system (CNS) might underlie a focal demyelinating disease such as MS. A shift from autoimmunity to a latent-virus model is not a trivial substitution of target antigens. This shift would expand the search for a definitive laboratory test for MS and could lead to improved therapeutic and preventive approaches.

Abstract
Immune responses to heat shock or stress proteins are observed in several chronic autoimmune diseases. Such proteins are major antigens of many bacteria, especially mycobacteria. To determine whether immune responses to stress proteins occur in chronic inflammatory diseases of the central nervous system such as multiple sclerosis (MS) we measured proliferative responses of lymphocytes from spinal fluids and bloods of patients with MS and other neurological diseases to a sonicate of M. tuberculosis, an acetone extract of M. tuberculosis, a recombinant 65-kd heat shock protein of M. leprae, and tetanus toxoid as a control recall antigen. Significantly increased spinal fluid lymphocyte responses to mycobacterial sonicate, relative to responses from paired peripheral blood lymphocytes, were present in 14 of 20 specimens from patients with MS (p < 0.025) and 2 of 9 specimens from patients with other neurological diseases. Spinal fluid lymphocytes also responded to tetanus toxoid, but differences between blood and spinal fluid were not statistically significant. Lymphocytes from 1 patient with MS responded only to M. leprae. There were no proliferative responses to the M. tuberculosis acetone extract. When patients with MS were classified according to duration of disease (< 2- or > 2-yr duration) 9 of 10 patients with recent onset had cerebrospinal fluid cells that responded to M. tuberculosis compared with 5 of 10 with longer duration symptoms (p < 0.012). Our data suggest a selective recruitment and/or expansion of mycobacterial reactive cells to the central nervous system of a subpopulation of patients with MS.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Staphylococcal enterotoxin B (SEB) is a superantigen (SA) that up-regulates and then subsequently down-regulates and deletes T cells expressing V beta 8 T cell receptor (TcR) chains (Marrack and Kappler, 1990; Johnson et al., 1991). We have investigated the effect of SEB on experimental allergic encephalomyelitis (EAE) in PL/J mice, where the predominant encephalitogenic T cells are V beta 8+ (Acha Orbea et al., 1988; Zamvil et al., 1988). SEB did not enhance induction of EAE when administered prior to or after immunization for EAE. PL/J mice pretreated with SEB developed anergy and deletion of V beta 8 bearing cells and concomitant reduction in the incidence of EAE. Following SEB pretreatment, a redistribution in the TcR utilization of MBP-specific lymphocytes occurred. As a result, there was a low frequency of V beta 8 and expansion of other, normally less frequent, myelin basic protein (MBP)-specific clones. These observations indicate that systemic exposure to superantigen can influence organ-specific autoimmune diseases. We observed V beta-specific elimination, rather than activation, of autoimmune clones, a finding of potential therapeutic value. Modification of the TcR repertoire by systemic exposure to this SA indicates plasticity of immune reactivity and demonstrates a mechanism by which an environmental exposure (SEB) can influence a genetically determined, T cell mediated autoimmune disease.

Abstract
As a further development from an earlier hypothesis, a pathogenic role of polyspecific natural, idiotypically connected antibodies is claimed, that recognize concomitantly a variety of CNS antigens and are matured to some degree to higher-affinity anti-CNS antibodies without ever losing their network association. On that basis, nitrophenol-carrier conjugates well-known to be foreign target antigens of natural antibodies and present in food commodities that have epidemiological links to MS, are considered as paradigmatic for agents of possible etiologic importance.

Abstract
Treatment of insulin-dependent diabetes remains problematic since there continues to be high rates of morbidity and mortality among affected patients. Good outcomes are most likely to be more common among patients who maintain endogenous insulin reserves for the longest time following diagnosis. The disease process can now be identified in its early, pre-symptomatic stages and thus, the time has come for the investigation of preventive therapies through multicenter clinical trials. A wide variety of strategies are available and their choice should be dependent on the pathogenic stage of disease at which treatment is initiated. This stage-specific approach to prevention is discussed with a particular focus on those therapies that will soon be tested in clinical trials.

Abstract
To investigate the mode of the pathogenesis of multiple sclerosis (MS), we transferred cerebrospinal fluid (CSF) cells, predominantly mononuclear cells, from MS patients at both exacerbation and remission stages of the disease into severe combined immunodeficiency mice by intracisternal injection. As controls, (i) CSF cells from patients with cervical spondylosis and (ii) peripheral blood mononuclear cells from normal individuals were transferred. Four to 6 weeks after transfer, most mice transferred with CSF cells from MS patients at the exacerbation stage of the disease developed paralysis and ataxia. The histopathological examination on the sacrificed mice revealed multiple scattered, discrete lesions localized in the white matter of the brainstems and spinal cords. These lesions were characterized by various degrees of tissue necrosis, involving inflammatory-cell infiltration. Most infiltrating cells were macrophages, although a smaller number of granulocytes appeared in several foci. Reactive astrocytic gliosis was also seen around the necrotic foci. Furthermore, these lesions exhibited demyelination. These histopathological changes are similar to those seen in MS. In contrast, none of the severe combined immunodeficiency mice transferred with CSF cells from MS patients at the remission stage of the disease, or with CSF cells from the patients with cervical spondylosis, or with peripheral blood mononuclear cells from normal individuals showed any such histopathological changes. These observations provide convincing direct evidence of encephalitogenicity of mononuclear cells in CSF from MS patients at the exacerbation stage of the disease.

Abstract
Multiple sclerosis (MS) is an inflammatory, demyelinating disease of the central nervous system in which large numbers of T cells enter the brain and cerebrospinal fluid (CSF). To determine whether these cells represent restricted populations, we studied expression of T-cell receptor V beta chains on paired samples from the central nervous system and blood of patients with MS or other neurological diseases (OND) using a quantitative polymerase chain reaction. The distribution of V beta chain expression in blood was skewed, with a significant preponderance of message from V beta genes 1 through 8 (p = 0.0001). Such skewing was not present in samples from the CSF and brain. Patterns of V beta gene expression were different among paired samples from spinal fluid and blood and were relatively heterogeneous. Blood and CSF samples from a patient with acute meningitis were studied on two separate occasions. The patterns of V beta expression changed over 72 hours in both the blood and the CSF. With one exception, no oligoclonal populations of T cells were observed nor were there disease-specific patterns of V beta gene expression in the blood or CSF. Samples from 2 MS brains and 1 OND brain expressed patterns of V beta genes that were different and less heterogeneous than those in paired blood. In addition, expression of V beta 12 was remarkably increased in the 2 MS brains, suggesting a selective recruitment or expansion of T cells expressing this gene. These data demonstrate that populations of T cells from blood, spinal fluid, and brain differ from one another and can fluctuate during periods of acute inflammation.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The repertoire of V regions of alpha/beta+ T cell receptor (TcR) on CD4+ and CD8+ T cells from the peripheral blood of six patients with a novel X-linked combined immunodeficiency was investigated by flow cytometry. The relative frequencies of V region subfamilies V alpha 2a on CD4+ T lymphocytes and V beta 5b and V beta 12a on CD8+ T lymphocytes from the peripheral blood from the affected males were decreased significantly. Also, the relative frequencies of certain other V region subfamilies on CD4+ or CD8+ T cells from the peripheral blood of some patients were either considerably below or above the ranges found in normal subjects. Although there may be other explanations including an extrathymic event, we suggest that the abnormalities in the TcR repertoire of peripheral blood T cells are consistent with a dysregulation of the intrathymic maturation/selection of T cells that leads to deficiencies in T cell populations in the peripheral blood of males with this disease.

Abstract
Multiple sclerosis (MS) is a presumed autoimmune disease of the central nervous system. Inoculation of attenuated T cell clones recognizing immunodominant regions of myelin autoantigens can protect animals from the induction of experimental autoimmune diseases. In this phase one trial, we investigated whether inoculations with attenuated T cell clones are feasible in humans for eventual trials with autoreactive clones and whether there are any associated immunologic effects. A total of seven inoculations with attenuated, autologous T cell clones isolated from the cerebrospinal fluid in four subjects with progressive MS was performed. No untoward side effects were observed. Immunologic studies suggested that the inoculation of autologous activated T cell clones followed by partial, short-term, immunosuppression as evidenced by a decrease of subsequent responses to stimulation via the CD2 pathway and increases in the autologous mixed lymphocyte response. We conclude that the use of attenuated autoreactive T cell clones appears feasible for further clinical trials in humans with autoimmune diseases.

Abstract
T cell receptor (TCR) peptide vaccines have proven useful in the prevention and treatment of autoimmune disease in animal models. Prospects for developing TCR peptide vaccines for human autoimmune disease are only now being explored. Preliminary indications provide cause for optimism that immunization with TCR peptides eventually will be a viable treatment option for autoimmune pathologies in humans. In the long term, development of this technology may permit reliable manipulation of T cell immunity, leading to treatments for autoimmunity, T lymphoproliferative disorders, and, in the broadest interpretation, any pathogenesis mediated by oligoclonal T cell populations.
