Abstract
In developing countries, one-third of reactive arthritis (ReA) cases are associated with Salmonella enterocolitis; nevertheless, there is no animal model for studying this pathology. Here we induced a self-limiting Salmonella enterica serovar Enteritidis enterocolitis in mice to analyze the onset of ReA. BALB/c mice received orally 20 μg of streptomycin 24 h before intragastric inoculation of a low dose (3 × 10(3) to 4 × 10(3) CFU) of S. Enteritidis. In response to Salmonella infection, a 30-fold increase in the expression of interleukin-17 (IL-17), measured by quantitative PCR, was observed in mesenteric lymph nodes 5 days postinfection. At this time synovitis was already evident, and concomitantly, a significant increase in joint tumor necrosis factor alpha (TNF-α) was detected by enzyme-linked immunosorbent assay (ELISA). The early development of joint lesions was accompanied by an increased expression of IL-17 in inguinal and popliteal lymph nodes. Infection with 10(7) CFU of an isogenic ΔinvG mutant bearing a defective type III secretion system of Salmonella encoded in the pathogenicity island 1 apparatus (TTSS-1) induced enterocolitis histologically similar to that triggered by the wild-type strain. Interestingly, despite the higher infective dose used, the mutant did not trigger intestinal IL-17. Moreover, no synovitis was observed in mice suffering ΔinvG enterocolitis. Neutralization of IL-17 in mice infected with S. Enteritidis prevented both synovitis and the increment of TNF-α in the joints, suggesting that IL-17 participates in the generation of Salmonella-induced ReA through the induction of TNF-α in the joints.

Abstract
Human T helper 1 (Th1) cells develop preferentially during infections by intracellular parasites and trigger phagocyte-mediated host defence. In contrast, human Th2 cells are responsible for phagocyte-independent host response, and they predominate during helminthic infestations and in atopic humans in response to common environmental antigens. Polarized human Th1 and Th2 cell responses play different roles in protection, and they can promote different immunopathological reactions. Strong and persistent Th1 responses seem to be involved in organ-specific autoimmunity, contact dermatitis and some chronic non-allergic inflammatory disorders. Polarized Th2 responses favour reduced protection against the majority of infections, including HIV, and they are responsible for triggering allergic disorders in genetically predisposed hosts. Th1 and Th2 cells probably exhibit distinct surface markers; for example, Th2 cells express preferentially membrane CD30 and release the soluble form of CD30, which is a member of the tumour necrosis factor receptor superfamily. CD30-mediated signalling promotes the in vitro development of Th2-like cells. The expression of CD30 in HIV-infected T cells results in enhanced HIV replication, suggesting the existence of complex links among CD30 expression, production of Th2-type cytokines and immunopathogenesis of HIV infection.

Abstract
Reactive arthritis (ReA) has been recognized as a clinical disease entity for nearly 100 years. The prevalence is estimated to be 30-40/100,000 adults. The HLA-B27-associated form is part of the spondyloarthritis concept. According to the current hypothesis the arthritis follows a primary extra-articular infection and is characterized by the presence of bacterial antigen and/or of viable but non-culturable bacteria persisting within the joint. Pathogenesis involves the modification of host cells by pathogen-associated molecular patterns (PAMPs, e.g. lipopolysaccharide), bacterial effector proteins, the adaptive immune system, and the genetic background. Up to 30% of patients develop chronic symptoms, and therapeutic options for these patients are still limited. Data for recommendations to apply conventional disease-modifying anti-rheumatic drugs (DMARDs) are rare; however, sulfasalazine seems to be effective, and first reports on agents that block tumour necrosis factor (TNF) are promising. Combination therapy of several antibiotics might open the window to curing the disease; however, controlled clinical studies are needed.

Abstract
OBJECTIVE Although Chlamydia trachomatis-induced arthritis is among the most common rheumatic diseases having an identified infectious trigger, the pathogenesis of this arthritis is not well defined. We sought to investigate the host-microbe interactions that contribute to the severity of arthritis initiated by chlamydial infection. METHODS We established an experimental rat model of C. trachomatis-induced arthritis that recapitulates many pathologic features of the clinical disease. The severity of the arthritis was defined using an established histopathologic scoring system. Host clearance of the pathogen and local cytokine production were examined by enzyme-linked immunosorbent assays. RESULTS Lewis rats were susceptible to C. trachomatis-induced arthritis, whereas BN rats were relatively resistant to this disease. Significant differences in the histopathologic severity of arthritis were originally observed on day 21, and this prompted an examination of the acute phase of the arthritis. As early as day 5 after the onset of the arthritis, pathologic changes in Lewis rats were more severe than those in BN rats. An evaluation of the role of complement using cobra venom factor treatment excluded complement as being the key to differential sensitivity, because decomplementation did not eliminate the differences in arthritis severity between Lewis and BN rats. Host clearance, in contrast, was significantly different between the rat strains, with BN rats showing more prompt and effective clearance of the pathogen from both synovial tissues and spleen compared with Lewis rats. Local cytokine profiles demonstrated that host resistance was characterized by enhanced synovial expression of tumor necrosis factor alpha, interferon-gamma (IFNgamma), and interleukin-4. CONCLUSION These studies demonstrated that cytokines thought to be proinflammatory in nature can play an important role in host defense in infection-triggered arthritis and serve to highlight the dynamic cytokine relationships that constitute effective host-pathogen interactions.

Abstract
Reactive arthritis (ReA) occurs after a preceding bacterial infection of the urogenital or gastroenteral tract. The bacteria triggering ReA persist in vivo and seem to be responsible for triggering an immune response. A cytokine imbalance with a relative lack of T-helper 1 cytokines may play an important role allowing these bacteria to survive. This seems to be relevant for manifestation and chronicity of the arthritis. For the chronic cases and cases evolving into ankylosing spondylitis, the interaction between bacteria and human leukocyte antigen B27 plays an additional crucial role. Among others, the arthritogenic peptide hypothesis is one way to explain this association. Human leukocyte antigen B27-restricted peptides from Yersinia and Chlamydia, which are stimulatory for CD8+ T cells derived from patients with ReA, have been identified. The exact role of such peptides for the pathogenesis of ReA and other spondyloarthritides still has to be defined.

Abstract
Chlamydia trachomatis-associated tubal factor infertility (TFI) involves enhanced humoral and cell-mediated immune response to the chlamydial 60 kDa heat shock protein (CHSP60). We evaluated the role of CHSP60-induced immune response in TFI by studying lymphocyte proliferation and cytokine (interferon (IFN)-gamma, interleukin (IL)-12 and IL-10) secretion in response to C. trachomatis elementary body (EB) and CHSP60 antigens in 57 women with TFI and in 76 women with other causes of infertility. Positive proliferative response of PBMC to CHSP60 was more common in the TFI group (20/57; 36%) than in the other groups (17/76; 22%) although the frequency or the median responses did not differ significantly (1.6, range 0.2-22.1 versus 1.4; 0.2-24.4). C. trachomatis EB induced significantly higher IFN-gamma and lower IL-10 secretion in the TFI group compared to the other groups. The EB and CHSP60 induced IL-12 secretion was similar in all study groups and correlated with IFN-gamma secretion in the other but not in the TFI group. The lack of correlation between EB-induced IL-12 and IFN-gamma production and simultaneously found prominent IL-10 secretion in response to CHSP60 in the TFI group suggests that the CHSP60 may have a specific role in regulating the immune reactions during chlamydial infection and may consequently contribute to the immunopathogenesis of TFI.

Abstract
Juvenile onset spondyloarthropathy (SpA) is a term that refers to a group of human leucocyte antigen (HLA)-B27 associated inflammatory disorders affecting children under the age of 16 years, producing a continuum of clinical symptoms through adulthood. This disease is characterised by enthesopathy and arthropathy affecting the joints of the lower extremities and seronegativity for IgM rheumatoid factor and antinuclear antibodies. Children usually present with undifferentiated SpA and progress to differentiated forms over time. Except for the prevalence of some clinical features at onset, the pathogenic and clinical aspects of juvenile onset SpAs resemble those of the adult disease. Thus application of the same or similar therapeutic measures for both juvenile and adult onset SpAs seems logical. Current treatments for juvenile onset SpA provide symptomatic improvement, but do not alter disease progression. The increased expression of tumour necrosis factor alpha (TNFalpha) in synovial tissue of patients with adult and juvenile onset SpA and its correlation with infiltration of inflammatory mediators into the synovia suggest a significant pathogenic role of this cytokine. Clinical trials of anti-TNFalpha antibody (infliximab) therapy in patients with adult onset SpA have demonstrated significant clinical improvement in inflammatory pain, function, disease activity, and quality of life in correlation with histological and immunohistochemical evidence of modulation of synovial inflammatory processes. These promising findings suggest that anti-TNFalpha therapy may confer similar benefits in patients with juvenile onset SpA.

Abstract
Synovitis of recent onset is a challenging problem, both from a diagnostic and a mechanistic point of view. The role of the immune system in mediating the systemic and synovial inflammatory response remains an area of active investigation. Studies in early synovitis cohorts have confirmed the relatively specific association of rheumatoid factor positive polyarthritis with a number of autoantibodies, particularly anticyclical citrullinated peptide (CCP) antibodies, antifilaggarin antibodies (AFA), and anti-Sa antibodies. Immunopathologic studies of synovial tissue samples from patients with early synovitis have generally suggested quantitative rather than qualitative differences between various forms of synovitis. In particular, Th1 cytokines appear to predominate in rheumatoid arthritis and psoriatic synovitis, while Th2 cytokines are more often detectable in the synovium of reactive arthritis patients. This latter observation is consistent with an immune response profile that favors persistence of intracellular organisms.

Abstract
OBJECTIVE To evaluate the role of chlamydial heat shock protein 60 (CHSP60)-specific T-lymphocytes in tubal factor infertility. DESIGN Case series of patients with tubal factor infertility. SETTING Infertility Clinic, Department of Obstetrics and Gynecology, Helsinki University Central Hospital and Laboratory of Cell-Mediated Immunity, National Public Health Institute, Oulu, Finland. PATIENT(S) Five patients with tubal factor infertility who underwent elective salpingectomy because of hydrosalpinges. INTERVENTION Collection of salpingeal tissue specimens for in vitro culture of T-lymphocytes. MAIN OUTCOME MEASURE(S) Cloning of Chlamydia trachomatis and CHSP60-specific T-lymphocyte lines derived from inflamed salpingeal tissue. Cytokine production analysis of the established T-lymphocyte clones. RESULT(S) Seventy-seven (34%) of the 229 T-lymphocyte clones recognized C. trachomatis and C. pneumoniae elementary bodies as target antigens. One-third of these Chlamydia genus-specific T-lymphocyte clones further recognized CHSP60 as the target antigen. Most of the CHSP60-specific T-lymphocyte clones produced predominantly IL-10. CONCLUSION(S) CHSP60 may be an important T-lymphocyte antigen involved in the immunopathogenesis of tubal damage associated with chronic C. trachomatis infection.

Abstract
OBJECTIVE Infection with Chlamydia trachomatis is a known cause of sexually transmitted diseases, eye infections (including trachoma), and reactive arthritis (ReA). Because the mechanisms of Chlamydia-induced changes leading to ReA are poorly defined, this study sought to identify the target genes involved at the molecular level. METHODS Chlamydia-induced changes in host cells were investigated by combining a screening technique, which utilized complementary DNA arrays on C trachomatis-infected and mock-infected epithelial HeLa cells, with real-time reverse transcription-polymerase chain reaction or enzyme-linked immunosorbent assay of gene products. Some responses were additionally demonstrated on human primary chondrocytes and a human synovial fibroblast cell line, both of which served as model cells for ReA. RESULTS Eighteen genes (of 1,176) were found to be up-regulated after 24 hours of infection with this obligate intracellular bacterium, among them the glycoprotein 130 family members IL-11 and LIF, the chemokine gene MIP2-alpha, the transcription factor genes EGR1, ETR101, FRA1, and c-jun, the apoptosis-related genes IEX-1L and MCL-1, adhesion molecule genes such as ICAM1, and various other functionally important genes. In the context of this rheumatic disease, the cytokines and transcription factors seem to be especially involved, since various connections to chondrocytes, synoviocytes, bone remodeling, joint pathology, and other rheumatic diseases have been demonstrated. CONCLUSION Infection with C trachomatis seems to reprogram the host cells (independent of activation by lipopolysaccharide or other ultraviolet-resistant bacterial components) at various key positions that act as intra- or intercellular switches, suggesting that these changes and similar Chlamydia-induced functional alterations constitute an important basis of the pathogenic inflammatory potential of these cells in ReA. Our results suggest that this approach is generally useful for the broad analysis of host-pathogen interactions involving obligate intracellular bacteria, and for the identification of target genes for therapeutic intervention in this rheumatic disease.

Abstract
An inflammatory arthritis is known to follow urogenital infection with the intracellular bacterium Chlamydia trachomatis in some individuals, and recent research results have elucidated important aspects of the characteristics of this Chlamydia-associated joint disease. Although the several extra-articular features of Chlamydia-induced arthritis have been defined clinically, their detailed causes remain largely unexplained. Current data indicate that the clinical characteristics of joint disease associated with C. trachomatis infection and those associated with postenteric arthritis are not easily distinguishable, although the response of each to antibiotic therapy does differ. The biologic characteristics of Chlamydia and enteric organisms in the joint show profound differences, and these are probably responsible for the variable responses to drug treatment. Molecular analyses of synovial C. trachomatis have demonstrated that long-term infection of the joint occurs primarily in synovial tissue and that the organism exhibits highly unusual biologic properties in its synovial context. These unusual molecular, biochemical, and other characteristics provide explanations for the frequent culture negativity of joint materials for C. trachomatis and for several other aspects of the arthritogenic process. Much remains to be learned concerning the behavior of this organism in the joint and concerning its interaction with its synovial host cells.

Abstract
OBJECTIVE To investigate possible differences in Th1 and Th2 cytokine mRNA expression in the synovial tissue (ST) of patients with rheumatoid arthritis (RA) and seronegative spondyloarthropathies (SpA) with diagnostic and/or pathogenic interest. METHODS Eleven RA patients and 14 SpA patients (10 with undifferentiated spondyloarthropathy (USpA), two with ankylosing spondylitis (AS) and two with psoriatic arthritis (PsA)) were included. Th1 (interferon gamma, interleukin 2) and Th2 (interleukin 4, interleukin 5 and interleukin 10) cytokine mRNA levels from arthritic knee ST were quantified by using an optimised polymerase chain reaction method with a computerised analysis system. Protein levels of proinflammatory cytokines (interleukin 1, tumour necrosis factor alpha and interleukin 6) in synovial fluid were quantified with a specific ELISA test. RESULTS Th1 cytokines were detected in all of RA ST samples in contrast with 58% (interferon gamma) and 71% (interleukin 2) of SpA samples. Th2 cytokines were expressed in 90% of RA ST samples, but the findings in SpA were interleukin 10 in 90%, interleukin 4 in 60% and interleukin 5 in 40% of ST samples. However, when the mRNA levels of each cytokine were quantified and corrected for T cell mRNA levels, only interferon gamma levels were significantly higher in RA than in SpA (p<0.003). Thus, the Th1/Th2 cytokine ratio in RA was fivefold that of SpA. Synovial fluid interleukin 1beta concentrations were higher in RA than in SpA (p<0. 05); there were also higher synovial fluid levels of tumour necrosis factor alpha in RA than in SpA, but without statistical significance. CONCLUSION This study has detected both Th1 and Th2 cytokine gene expression in ST from RA and SpA patients. Synovium interferon gamma mRNA levels and SF interleukin 1beta protein levels were significantly higher in RA than in SpA, so reflecting the known proinflammatory activity of interferon gamma through macrophage activation. Thus, the Th1 (interferon gamma)/Th2 (interleukin 4) ratio is significantly higher in RA than in SpA ST. These data confirm previous studies on ST Th1/Th2 balance in RA and extend previous work in comparing ST RA with subgroups of SpA distinct of ReA.

Abstract
We previously identified a protein that was stimulatory for malignant Sézary T cells, termed Sézary T-cell activating factor (SAF). However, the identity of this protein has not been fully elucidated, nor has it's role been determined in the pathogenesis of cutaneous T-cell lymphoma (CTCL). The basis for epidermotropism and proliferation of malignant cells in the skin of patients with CTCL is unknown. Using a monoclonal antibody inhibitory for SAF activity, we demonstrated that SAF is present in the skin of 16 of 27 samples from patients with mycosis fungoides, the predominant form of CTCL. In this report, the SAF determinant is demonstrated to be associated with Chlamydia pneumoniae bacteria by immunohistochemistry, immunoelectron microscopy, and culture analysis. Reactivity of antibodies against an outer membrane protein of C. pneumoniae or against the lipopolysaccharide of Chlamydiae spp. demonstrated that these determinants are coexpressed in 90% of the SAF-positive samples. We confirmed the presence of C. pneumoniae DNA and RNA in the skin by PCR and reverse transcription-PCR and by sequence analysis of the PCR products. The expression of the C. pneumoniae antigens and SAF appears to be associated with active disease in that C. pneumoniae antigens were absent or greatly diminished in the skin of three patients examined after Psoralen and long-wave UVA radiation treatment. Our results suggest that SAF is a Chlamydia-associated protein and that further investigation is warranted to determine whether SAF and C. pneumoniae play a role in the pathogenesis of CTCL.

Abstract
In contrast to rheumatoid arthritis (RA), the triggering antigens are known in reactive arthritis (ReA) and Lyme arthritis. Thus, in these arthritides the antigen-specific T-cell response can be investigated in much detail and lessons possibly learned for other spondyloarthropathies (SpA) such as ankylosing spondylitis (AS) where T cells may well also play an important role in the pathogenesis. This article focusses on the immunopathology of the SpA, ReA, and AS with special reference to T cells and cytokines.

Genetically determined differences in interleukin-10 (IL-10) and gamma interferon (IFN-gamma) responses in mice correlate with clearance of Chlamydia pneumonitis infection. We measured the synovial expression of IL-10 and IFN-gamma and additional cytokine genes in patients who had recent-onset Chlamydia-associated arthritis (Chl-AA). IL-10 and IFN-gamma mRNA were relatively abundant in recent-onset Chl-AA.

Abstract
The balance between Th1 and Th2 cells regulates the choice between inflammatory and antibody-mediated immune responses. To an increasing extent this balance is thought to involve the participation of antigen-presenting cells, rather than the entirely autonomous activity of T cells and their cytokines. Here we survey current opinion concerning the working of this balance, and its condition in rheumatoid arthritis and the other inflammatory arthritides. The contrast between Lyme arthritis and reactive arthritis is particularly illuminating, since one is triggered by extracellular and the other by intracellular infection. We describe current approaches to the modulation of this balance. Guided by the principles that genetic polymorphism is likely to identify relevant genes, that any cytokine gene picked up by a virus must matter and that natural immunosuppressive activity at mucosal surfaces should be worth exploiting, we identify as particularly worthy of attention: (i) IL-10, (ii) inhibitors of IL-12 production, (iii) inhibitors of CD40 ligand expression and (iv) oral and nasal tolerance. Other protective T cell subsets are touched on, and the impact of oligonucleotide arrays mentioned.

Abstract
Cell-mediated immune (CMI) responses play a major role in protection as well as pathogenesis of many intracellular bacterial infections. In this study, we evaluated the infection kinetics and assessed histologically the lymphoid reactions and local, in vitro-restimulated CMI responses in lungs of BALB/c mice, during both primary infection and reinfection with Chlamydia pneumoniae. The primary challenge resulted in a self-restricted infection with elimination of culturable bacteria by day 27 after challenge. A mild lymphoid reaction characterized the pathology in the lungs. In vitro CMI responses consisted of a weak proliferative response and no secretion of gamma interferon (IFN-gamma). The number of lung-derived mononuclear cells increased substantially during the primary infection; the largest relative increase was observed in B cells (B220(+)). After reinfection, the number of lung-derived mononuclear cells increased further, and the response consisted mainly of T cells. The reinfection was characterized in vivo by significant protection from infection (fewer cultivable bacteria in the lungs for a shorter period of time) but increased local lymphoid reaction at the infection site. In vitro, as opposed to the response in naive mice, acquired immunity was characterized by a strongly Th1-biased (IFN-gamma) CMI response. These results suggest that repeated infections with C. pneumoniae may induce Th1-type responses with similar associated tissue reactions, as shown in C. trachomatis infection models.

Abstract
In the spondyloarthropathies human leukocyte antigen (HLA) B27 confers a strong genetic predisposition to the development and to the chronicity of disease after extra-articular infection with certain gram-negative bacteria. The close relationships between infection, HLA-B27, other genetic factors, and the host immune system, however, still are unexplained. HLA-B27-positive arthritis continues to be an area of intensive investigation in basic and clinical research. New animal models with HLA-B27 transgenic mice and rats, as well as recent developments in understanding the processes involved in signal transduction, cytokine production, and human T-lymphocyte activation, contribute to the development of new pathogenic models of the spondyloarthropathies. This article summarizes the current concepts of the cause and pathogenesis of the spondyloarthropathies resulting from studies of clinical materials. The host-microbial interplay in human disease, namely in bacteria-induced reactive arthritis, may eludicate principle disease mechanisms in acute disease and in the development of chronic autoimmune arthritis or ankylosing spondylitis.

Abstract
PURPOSE Trachoma, a chronic follicular conjunctivitis caused by infection with Chlamydia trachomatis, is the leading cause of preventable blindness. The blinding complications are associated with progressive conjunctival scarring that may result from immunologically mediated responses. We studied the processes involved in the regulation of inflammation and fibrosis in trachoma by investigating the expression of fibrogenic cytokines in the conjunctiva. METHODS We studied conjunctival biopsy specimens obtained from nine subjects with active trachoma and from four control subjects. We used immunohistochemical techniques and a panel of monoclonal and polyclonal antibodies directed against interleukin-1 alpha (IL-1 alpha), interleukin-1 beta (IL-1 beta), tumour necrosis factor-alpha (TNF-alpha) and platelet-derived growth factor (PDGF). In addition, we characterised the composition of the inflammatory infiltrate by the use of a panel of monoclonal antibodies. Sirius red and Van Gieson stains were used to characterise the extent of fibrous tissue in the substantia propria. RESULTS Trachoma specimens showed greater numbers of inflammatory cells than control specimens. The expression of cytokines was absent in the normal conjunctiva. Cytoplasmic IL-1 alpha and IL-1 beta expression was noted in the conjunctival epithelium in all trachoma specimens. IL-1 alpha, IL-1 beta, TNF-alpha and PDGF were detected in macrophages infiltrating the substantia propria. B lymphocytes predominated over T lymphocytes in six trachoma biopsies with fibrosis confined to the deep substantia propria, whereas T lymphocytes predominated over B lymphocytes in three biopsies with more extensive fibrosis. In all trachoma biopsies helper/inducer T lymphocytes outnumbered suppressor/cytotoxic T lymphocytes. CONCLUSIONS The upregulated local production of IL-1 alpha, IL-beta, TNF-alpha and PDGF might contribute to conjunctival damage and scarring in trachoma.

Abstract
Infection of fibroblast-like synovial cells with Chlamydia trachomatis (serotype D strain IC Cal 8) in culture induced the secretion of beta interferon (IFN-beta). Chlamydial infection inhibited IFN-gamma-induced expression of HLA-DR antigen in the cells. Addition of IFN-beta antibody directly to infected cultures mitigated HLA-DR inhibition, suggesting involvement of produced IFN-beta.

Abstract
We have evaluated the effects of three potent immunosuppressive agents, cyclosporin A (CsA), FK506 and rapamycin, on the murine contact sensitivity (CS) reaction to the hapten trinitrochlorobenzene. Development of CS reaction requires participation of three distinct T cell subsets: alphabeta+, CD4+ T lymphocytes, which are the classical effector cell of the CS reaction, gammadelta+ T lymphocytes, and alphabeta+, double-negative (CD4- CD8-) T lymphocytes that express the B220 molecule and produce IL-4. We found that all three drugs inhibit the development of the CS reaction, but they affect different target cells. In fact, rapamycin and FK-506 block both alphabeta+, CD4+ and gammadelta+ T lymphocytes, while CsA inhibits only the alphabeta+, CD4+ T lymphocyte. None of the three drugs exerted any inhibitory activity on the alphabeta+, double-negative (CD4- CD8-) T lymphocytes. Hapten-immune lymph node cells from mice treated in vivo with CsA or FK506 failed to proliferate and to produce IL-2 when re-exposed to the specific antigen in vitro. In contrast, immune lymph node cells from mice that had been treated in vivo with rapamycin gave optimal antigen-specific proliferation and IL-2 production in vitro. The implications of these observations are discussed in relation to the use of these immunosuppressive agents for prevention of allograft rejection.

Abstract
Abstract
Cytokines produced by subsets of CD4+ T helper cells responding to an infection influences the efficiency with which the host is able to mount a protective immune response. In an attempt to elucidate the population of active cells involved in the propagation of Lyme arthritis we have utilized intracellular cytokine staining to analyze the polyclonal immune response at the single cell level. We have determined the Th phenotype in the synovial fluid of patients with a variety of chronic inflammatory arthritides, including patients representative of the spectrum of Lyme arthritis. Th1 cells dominate the immune response in the synovial fluid of patients with Lyme as well as those with rheumatoid or other types of chronic inflammatory arthritis. In addition, the severity of Lyme arthritis directly correlates with the ratio of Th1 to Th2 cells in the synovial fluid, such that the larger the effusion, the higher the ratio (r = 0.67, p < 0.05). These results suggest that Th1 cells play a direct role in the pathogenesis of the inflammatory process seen in Lyme arthritis, and that Th2 cells modulate the pro-inflammatory response generated by Th1 cells in the joint. Finally, we identify Th1 cells specific for outer surface protein A of Borrelia burgdorferi, the agent of Lyme disease. These cells are restricted to patients with Lyme arthritis and are localized to the joint. Furthermore, they persist in patients with prolonged antibiotic treatment-resistant Lyme arthritis, suggesting the possibility of an autoimmune process.

Abstract
OBJECTIVE To investigate whether a predominant type 1 T helper (Th1) or Th2 cytokine pattern is present in the joints of patients with reactive arthritis (ReA), and whether the cytokine pattern can be modulated by cytokines or anticytokines. METHODS Eleven patients with ReA following infection with either Chlamydia trachomatis, Yersinia enterocolitica, or Salmonella enteritidis were investigated for the presence of Th1/Th2 cytokines in the joints. Release of the bacteria-specific cytokines interferon-gamma (IFN gamma), tumor necrosis factor alpha (TNF alpha), interleukin-10 (IL-10), and IL-4 was measured in synovial fluid mononuclear cells (SFMC) using enzyme-linked immunosorbent assay and polymerase chain reaction. In the synovial membrane, secretion of IFN gamma and IL-4 was determined by immunohistologic analysis. Cytokine regulation was studied by adding cytokines and anticytokines to the cultures. RESULTS Upon stimulation with specific bacteria, SFMC secreted low amounts of IFN gamma and TNF alpha, but high amounts of IL-10. IL-10 was responsible for the suppression of IFN gamma and TNF alpha, as judged by the effect of adding either anti-IL-10 antibodies or exogenous IL-10 to these cultures. The addition of neutralizing anti-IL-12 to the cultures completely abolished the effects of anti-IL-10, suggesting that inhibition of the Th1-like cytokines by IL-10 is mediated through suppression of IL-12 synthesis. Exogenous IL-12 clearly enhanced IFN gamma and TNF alpha secretion. In the synovial membrane, a higher number of cells were positive for the Th2 cytokine IL-4, compared with the amount of IFN gamma-secreting cells. CONCLUSION These data indicate that a Th2 cytokine pattern predominates in the joints of patients with ReA. Since Th1 cytokines are necessary for the elimination of ReA-associated bacteria, Th2 cytokines might contribute to bacterial persistence in the joint. Therefore, the IL-10/IL-12 balance appears to be crucial for regulation of the cytokine pattern in the joints of patients with ReA.

Abstract
Lyme disease, caused by Borrelia burgdorferi, causes a multisystem inflammatory ailment, although the precise means of tissue damage are not well understood. It is clear that the organism is present at the site of inflammation in many organs and that many of the features of the illness are relieved by antibiotic therapy. A complex interaction between spirochete and immune systems of a number of mammalian hosts, in human disease and animal models, has been described. It is clear that T cells and macrophages are intimately associated with the pathogenesis of arthritis and that immune mechanisms are involved in other aspects of disease. Inflammation directed at persistence of Borrelial antigens is a plausible explanation for persisting arthritis. Autoimmunity based on molecular mimicry may play a role in the pathogenesis of Lyme disease. Humoral immunity plays a protective role, prompting interest in vaccine development. Significant variation in certain of the outer surface proteins suggests that multiple proteins, peptides, or chimeric vaccines may be needed to provide a sufficiently broad humoral protective response.

Abstract
OBJECTIVE To investigate whether type 1 helper (Th1) or Th2 cytokines are found in the joints of patients with Lyme arthritis, and whether the cytokine pattern can be modulated by cytokines or anticytokines. METHODS The cytokine pattern in the joints of 10 patients with Lyme arthritis was investigated. Expression of interferon-gamma (IFN gamma), tumor necrosis factor alpha (TNF alpha), interleukin-4 (IL-4), and IL-10 was measured by enzyme-linked immunosorbent assay (ELISA), after stimulation of synovial fluid mononuclear cells (SFMC) with Borrelia burgdorferi (Bb) in the supernatant. Expression of cytokine messenger RNA and protein in synovial membrane (SM) and nonstimulated SFMC was studied using semiquantitative reverse transcriptase-polymerase chain reaction and immunohistologic techniques. The effects of recombinant cytokines or neutralizing anticytokine antibodies on cytokine production in Bb-stimulated SFMC were investigated by ELISA. RESULTS SFMC produced high amounts of IFN gamma and TNF alpha, but little or no IL-4, upon stimulation with Bb antigen, indicating a Th1-type cytokine pattern. In SM, IFN gamma was detectable in all patients, while the other cytokines were less frequently found. Serial sections of SM revealed that all cytokines were located in the same area. The Th1 response, especially the production of TNF alpha, could be down-regulated in vitro by both endogenous and exogenous IL-10, but not by IL-4 or anti-IL-12. CONCLUSION A Th1-type cytokine pattern was found in the joints of patients with Lyme arthritis. This Th1 response could be down-regulated by IL-10, suggesting insufficient IL-10 production in vivo.

Abstract
In the mid-1980s, Mosmann, Coffman, and their colleagues discovered that murine CD4+ helper T-cell clones could be distinguished by the cytokines they synthesized. The isolation of human Th1 and Th2 clones by Romagnani and coworkers in the early 1990s has led to a large number of reports on the effects of Th1 and Th2 on the human immune system. More recently, cells other than CD4+ T cells, including CD8+ T cells, monocytes, NK cells, B cells, eosinophils, mast cells, basophils, and other cells, have been shown to be capable of producing "Th1" and "Th2" cytokines. In this review, we examine the literature on human diseases, using the nomenclature of type 1 (Th1-like) and type 2 (Th2-like) cytokines, which includes all cell types producing these cytokines rather than only CD4+ T cells. Type 1 cytokines include interleukin-2 (IL-2), gamma interferon, IL-12 and tumor necrosis factor beta, while type 2 cytokines include IL-4, IL-5, IL-6, IL-10, and IL-13. In general, type 1 cytokines favor the development of a strong cellular immune response whereas type 2 cytokines favor a strong humoral immune response. Some of these type 1 and type 2 cytokines are cross-regulatory. For example, gamma interferon and IL-12 decrease the levels of type 2 cytokines whereas IL-4 and IL-10 decrease the levels of type 1 cytokines. We use this cytokine perspective to examine human diseases including infections due to viruses, bacteria, parasites, and fungi, as well as selected neoplastic, atopic, rheumatologic, autoimmune, and idiopathic-inflammatory conditions. Clinically, type 1 cytokine-predominant responses should be suspected in any delayed-type hypersensitivity-like granulomatous reactions and in infections with intracellular pathogens, whereas conditions involving hypergammaglobulinemia, increased immunoglobulin E levels, and/or eosinophilia are suggestive of type 2 cytokine-predominant conditions. If this immunologic concept is relevant to human diseases, the potential exists for novel cytokine-based therapies and novel cytokine-directed preventive vaccines for such diseases.

Abstract
OBJECTIVE To investigate the biologic state of Chlamydia and its surface antigen expression in the synovial membranes of patients with Chlamydia-associated reactive arthritis/Reiter's syndrome (ReA/RS). METHODS Expression of chlamydial lipopolysaccharide (LPS), major outer membrane protein (MOMP), and elementary body (EB) antigens was studied by gold labeling immunoelectron microscopy on 6 synovial membrane and 2 synovial fluid (SF) pellet samples from 6 patients with Chlamydia-associated arthritis. The study findings were compared with 24-hour cultures of HeLa cells infected with Chlamydia trachomatis EB. RESULTS Persistent C trachomatis infection was found in all 6 synovial membrane samples from patients who had either early or chronic arthritis. The infection persisted despite antibiotic treatment, including a 1-month course of doxycycline therapy. Most persistent organisms were atypical reticulate bodies (RBs) found in both fibroblasts and macrophages. Specific, but weak, immunogold staining for all 3 antibodies was found on both intracellular RBs and extracellular EBs. In the SF samples, Chlamydia surface antigens were detected only in phagosomes containing degraded electron-dense materials. CONCLUSION The synovial membrane biopsies conducted in this study of Chlamydia-associated ReA/RS revealed atypical RBs with diminished MOMP and LPS expression. Such altered organisms may escape immune surveillance and contribute to disease chronicity; moreover, these organisms may be difficult to detect and treat in some ReA/RS patients.

Abstract
A critical role for cell-mediated immunity (CMI) has been demonstrated for effecting the resolution of genital infections of mice infected intravaginally with the mouse pneumonitis biovar of Chlamydia trachomatis (MoPn). However, little is known about expression of CMI in the murine genital tract. The mouse MoPn model was used to examine CMI responses in the genital tract and associated lymph nodes during the course of infection. MoPn-specific lymphocytes were present in the genital mucosa, with the maximum level of proliferation in response to MoPn at 3 weeks postinfection. MoPn-stimulated cells secreting gamma interferon were also detected in the cells from the genital mucosa, but few interleukin-4-secreting cells were seen at any time postinfection, indicating the induction of a Th1-like response in the cells of the genital mucosa. The iliac node draining the genital tract was the major node stimulated as a result of a genital infection and exhibited a predominant Th1-like pattern of cytokine secretion as well. Mesenteric lymph node cells demonstrated poor proliferative responses to MoPn and few antigen-stimulated cytokine-secreting cells after the primary infection. However, 7 days after a second infection administered 50 days following the primary infection, there was a marked increase in both proliferative responses and the frequencies of MoPn-stimulated gamma interferon- and interleukin-4-secreting cells. These studies provided information regarding the local CMI response to MoPn in mice which may prove valuable in the development of vaccination strategies for the prevention of chlamydial genital infections.

Abstract
OBJECTIVE To investigate mechanisms involved in inflammation and new bone formation in the sacroiliac (SI) joints of patients with ankylosing spondylitis (AS). PATIENTS AND METHODS Computed tomography-assisted biopsy of the SI joint was performed in 5 patients with AS with a mean disease duration of 4.5 years and radiographic stage 2-3 disease. Immunohistologic studies were performed with the alkaline phosphatase-anti-alkaline phosphatase technique, and cytokine messenger RNA (mRNA) was detected by in situ hybridization. RESULTS Dense cellular infiltrates with varying amounts of CD3+ cells (mean +/- SD 53.3 +/- 24.1%), CD4+ cells (29.7 +/- 17.6%), CD8+ cells (15.8 +/- 11.4%), CD14+ cells (23.6 +/- 16.9%), CD45RO+ cells (48.4 +/- 23.6%), and CD45RA+ cells (4.5 +/- 2.9%) were found in the synovial portion of the SI joints of all 5 patients. In these infiltrates a high amount of tumor necrosis factor alpha (TNF alpha) mRNA and, near the site of new bone formation, a lower amount of transforming growth factor beta (TGF beta) mRNA, were detected, while no message for interleukin-1 was found in the 3 patients examined by this technique. CONCLUSION The presence of T cells and macrophages was demonstrated in cellular infiltrates in the SI joints of 5 patients with active AS. The finding of abundant TNF alpha message in these joints could have implications regarding potential immunotherapeutic approaches to this disease. TGF beta might be involved in new bone formation in AS.

Abstract
We have evaluated the effects of three potent immunosuppressive agents: cyclosporin A, FK506, and rapamycin, on a murine chronic graft-versus-host response (chronic GVHR). The chronic GVHR has previously been described to be a Th2-like response, and is characterized by a marked splenomegaly and hyper-IgE production in the early stages of the response. The effects of the immunosuppressive agents on both splenomegaly and hyper-IgE were measured 3 weeks after the induction of the chronic GVHR. Rapamycin was found to inhibit both splenomegaly and the hyper-IgE response in a dose-dependent manner. Unexpectedly cyclosporin A and FK506 were found to potentiate markedly both the splenomegaly and hyper-IgE response at low doses before exhibiting an inhibitory effect at higher doses. We propose the differences of activity seen with rapamycin compared with cyclosporin A and FK506 may be explained by their different mechanisms of action, and also by the selectivity of low dose cyclosporin A and FK506 for Th1-like lymphocytes. The implications of these observations are discussed in relation to the use of these immunosuppressives for the treatment of Th2-like diseases.

Abstract
The host response to Borrelia burgdorferi is likely to play a role in the pathogenesis of Lyme arthritis. Whereas most patients with Lyme arthritis can be cured with antibiotic therapy, approximately 10% of the patients have persistent arthritis for months or even several years after antibiotic treatment. In this study, we tested the hypothesis that the T cell response to one or more antigens of B. burgdorferi is different in patients with treatment-responsive or treatment-resistant Lyme arthritis. For this purpose, 313 B. burgdorferi-specific T cell lines were derived from the synovial fluid or peripheral blood of four patients with treatment-responsive Lyme arthritis and five patients with treatment-resistant arthritis. 87 T cell lines from treatment-responsive Lyme arthritis and 112 lines from the treatment-resistant group were examined for the recognition of five recombinant. B. burgdorferi proteins: outer surface proteins A (OspA), B, C, p39, and p93. In both groups of patients, the T cell lines frequently recognized OspB, and only occasionally recognized OspC, p39, and p93. In contrast, OspA was preferentially recognized by T cell lines from patients with treatment-resistant arthritis, but only rarely recognized by T cell lines from patients with treatment-responsive arthritis (odds ratio 28.4, 95% confidence interval 9.2-87.8, p < 0.005). These results are compatible with the hypothesis that the T cell response to B. burgdorferi OspA is involved in the pathogenesis of treatment-resistant Lyme arthritis.

Abstract
A major immunoregulatory mechanism in inflammatory infections and allergic diseases is the control of the balance of cytokines secreted by Th1/Th2 subsets of T helper (Th) cells. This might also be true in autoimmune diseases; a Th2 pattern that prevents an effective immune response in infections with intracellular bacteria may favor immunosuppression in autoimmune disease. The pattern of cytokine expression was compared in the synovial tissue from patients with a typical autoimmune disease, rheumatoid arthritis, and with a disorder with similar synovial pathology but driven by persisting exogenous antigen, reactive arthritis. We screened 12 rheumatoid and 9 reactive arthritis synovial tissues by PCR and in situ hybridization for their expression of T-cell cytokines. The cytokine pattern differs significantly between the two diseases; rheumatoid arthritis samples express a Th1-like pattern whereas in reactive arthritis interferon gamma expression is accompanied by that of interleukin 4. Studying the expression of cytokines by in situ hybridization confirmed the results found by PCR; they also show an extremely low frequency of cytokine-transcribing cells. In a double-staining experiment, it was demonstrated that interleukin 4 is made by CD4 cells. These experiments favor the possibility of therapeutic intervention in inflammatory rheumatic disease by means of inhibitory cytokines.
