Abstract
Compared to the general population, patients with arthritis have a higher risk of fertility abnormalities, which have deleterious effects on both reproductive function and pregnancy outcomes, especially in patients wishing to conceive. These may be due to the disease itself or those of drug therapies. Despite the increasing use of rituximab in arthritis, limited data are available on its potential to induce aneuploidy in germ cells. Therefore, the aim of the current investigation was to determine if repeated treatment with rituximab affects the incidence of aneuploidy and redox imbalance in arthritic mouse sperm. Mice were treated with 250 mg/kg rituximab once weakly for 3 weeks, and then sperm were sampled 22 days after the last dose of rituximab. Fluorescence in situ hybridization assay with chromosome-specific DNA probes was used to evaluate the disomic/diploid sperm. Our results showed that rituximab had no aneuploidogenic effect on the meiotic stage of spermatogenesis. Conversely, arthritis induced a significantly high frequency of disomy, and treatment of arthritic mice with rituximab reduced the increased levels of disomic sperm. The occurrence of total diploidy was not significantly different in all groups. Reduced glutathione and8-hydroxydeoxyguanosine, markers of oxidative stress were significantly altered in arthritic animals, while rituximab treatment restored these changes. Additionally, arthritis severity was reduced after rituximab treatment. We conclude that rituximab may efficiently alleviate the arthritis-induced effects on male meiosis and avert the higher risk of abnormal reproductive outcomes. Therefore, treating arthritic patients with rituximab may efficiently inhibit the transmission of genetic anomalies induced by arthritis to future generations.

Abstract
Rheumatoid arthritis (RA), an autoimmune disorder in which the immune system attacks healthy cells, is associated with elevated risk of lymphoma. Rituximab, a treatment for non-Hodgkin's lymphoma, has been approved as a treatment for RA. We studied the effects of rituximab on chromosomal stability in collagen-induced arthritis DBA/1J animal models. Micronucleus levels were increased in the mouse models, mainly due to chromosome loss, as detected by fluorescence in situ hybridization; rituximab-treated arthritic mice had significantly less micronucleus formation. Serum 8-hydroxydeoxyguanosine, a DNA oxidative stress marker, was increased in the mice models but reduced following rituximab administration.

Abstract
Chronic inflammatory diseases are triggered by causal stimuli that might occur long before the appearance of the symptoms. Increasing evidence suggests that these stimuli are necessary but not always sufficient to induce the diseases. The murine model of type II collagen emulsified in Freund's incomplete adjuvant (collagen-induced arthritis) to induce rheumatoid arthritis (RA) follows this pattern as some animals do not develop the chronically inflamed phenotype. Considering that in the immune-pineal axis (IPA) theory adrenal-pineal cross-talk adjusts early phases of inflammatory processes, we investigated whether differences in IPA activation could explain why some animals are resistant (RES) while others develop RA. We observed a similar increase in 6-sulfatoxymelatonin (aMT6s) excretion from day 3 to 13 in both RES and RA animals, followed by a significant decrease in RA animals. This pattern of aMT6s excretion positively correlated with plasma corticosterone (CORT) in RES animals. Additionally, RA animals presented a lower aMT6s/CORT ratio than saline-injected or RES animals. Plasmatic levels of tumour necrosis factor were similar in both groups, but interleukin (IL)-1β and monocyte chemotactic protein 1 (MCP-1) levels were lower in RES compared to RA animals. IL-2 and IL-4 were decreased in RES animals compared to saline-injected animals. The aMT6s/CORT ratio inversely correlated with the paw thickness and the inflammatory score (levels of IL-1β, MCP-1, IL-2 and IL-4 combined). Thus, adrenocortical-pineal positive interaction is an early defence mechanism for avoiding inflammatory chronification. KEY POINTS: Immune-pineal axis imbalance is observed in early-phase rheumatoid arthritis development. Only resistant animals present a positive association between adrenal and pineal hormones. The 6-sulfatoxymelatonin/corticosterone ratio is decreased in animals that develop rheumatoid arthritis. The inflammatory score combining the levels of nocturnal interleukin (IL)-1β, monocyte chemotactic protein 1, IL-2 and IL-4 presents a very strong positive correlation with the size of inflammatory lesion. The 6-sulfatoxymelatonin/corticosterone ratio presents a strong negative correlation with the inflammatory score and paw oedema size.

Abstract
Inducible costimulator (ICOS) and its ligand (ICOSL) are critical to regulate the immune response in autoimmune diseases. The participation of B lymphocytes exhibits pathogenic potential in the disease process of rheumatoid arthritis (RA). However, the precise role of ICOSL in RA remains unclear. In this study, we aimed to explore the regulatory effects of CD19+ICOSL+ B cells in the pathogenesis of RA. We demonstrated the increased expression of ICOS and ICOSL in patients with RA and collagen-induced arthritis (CIA) mice. The population of CD19+ICOSL+ B-cell subset was significantly correlated with clinicopathological characteristics of RA patients and CIA mice. Adoptive transfer of CD19+ICOSL+ B cells aggravated arthritic progression in CIA mice. Moreover, microarray analysis revealed that CD19+ICOSL+ cells could exert pivotal effect in pathological process of RA. Further blocking of ICOSL significantly inhibited proinflammatory responses and ameliorated arthritic progression. Therefore, CD19+ICOSL+ B-cell subset could be defined as a specific pathogenic cell subpopulation involved in immunopathological damage of RA. Blockade of ICOSL is promising to be a potential new approach for RA therapy.

Abstract
Rheumatoid arthritis (RA), which is driven by persistent activation of the immune system, primarily affects the joints. Several reports have estimated the risk of gonadal disruptions in arthritic patients, with potential attributable risk factors such as treatments with the disease-modifying antirheumatic drugs and the influence of the disease itself. The FDA approved rituximab, a therapy for non-Hodgkin's lymphoma, for management of RA in February 2006. However, the influence of repeated treatment with rituximab on gonadal function in RA has not been reported yet. Thus, the aim of the presents study is to evaluate whether repeated treatment with the clinically relevant dose of rituximab may change the gonadal disruptions in collagen-induced arthritis in male DBA/1 J mouse, a model of RA. Testicular disruptions, as determined by the sperm DNA strand breaks, spermatocyte chromosomal analysis and spermiogram examination have been conducted by the use of standard techniques. Additionally, we aimed to test whether the anti-rheumatic effect of rituximab also decreases the cellular oxidant-antioxidant imbalance in arthritic male DBA/1 J mice. Repeated treatment of naïve control DBA/1 J mice with rituximab did not exhibit any significant deleterious effects. Moreover, repeated administration of rituximab to the arthritic DBA/1 J mice suppressed disease severity and decreased testicular disruptions. Rituximab treatment also diminished gonadal oxidative stress, through decreasing reactive oxygen species generation and restoring the reduced glutathione level in arthritic DBA/1 J mice. In conclusion, rituximab is a safe therapeutic agent and can mitigate gonadal disruptions induced by arthritis, which insinuates the importance for arthritic patients especially at reproductive age.

Abstract
Purpose Low-dose interleukin-2 (ld-IL-2) has been shown to regulate the balance between effector T and regulatory T (Treg) cells and has been used in several clinical trials to treat autoimmune diseases including rheumatoid arthritis (RA). In this study, we investigated the effects of ld-IL-2 on collagen-induced arthritis (CIA) in mice. Methods Arthritis severity in CIA mice was measured using the arthritis index (AI), radiographs, and hematoxylin and eosin staining. Cytokines were detected using enzyme-linked immunosorbent assay. Gut microbiota alterations and short-chain fatty acid production were analyzed through 16S rRNA sequencing and gas chromatography. Results The AI scores of CIA mice treated with ld-IL-2 were significantly lower compared to the model group, which significantly reduced the severity of arthritis. Ld-IL-2 also altered the gut microbiota in CIA mice. The diversity, composition, and dominant species of gut microbiota were altered by ld-IL-2 treatment. Ld-IL-2 also increased short-chain fatty acid levels. There was a strong correlation between ld-IL-2 treatment and improved gut microbiota. Conclusion Ld-IL-2 significantly ameliorated joint inflammation and bone damage and improved gut microbial dysbiosis in CIA, indicating that it may be a promising therapy for RA patients.

Abstract
Rheumatoid arthritis (RA) is an autoimmune disease characterized by chronic systemic inflammation causing progressive joint damage that can lead to lifelong disability. The pathogenesis of RA involves a complex network of various cytokines and cells that trigger synovial cell proliferation and cause damage to both cartilage and bone. Involvement of the cytokines tumor necrosis factor (TNF)-α and interleukin (IL)-6 is central to the pathogenesis of RA, but recent research has revealed that other cytokines such as IL-7, IL-17, IL-21, IL-23, granulocyte macrophage colony-stimulating factor (GM-CSF), IL-1β, IL-18, IL-33, and IL-2 also play a role. Clarification of RA pathology has led to the development of therapeutic agents such as biological disease-modifying anti-rheumatic drugs (DMARDs) and Janus kinase (JAK) inhibitors, and further details of the immunological background to RA are emerging. This review covers existing knowledge regarding the roles of cytokines, related immune cells and the immune system in RA, manipulation of which may offer the potential for even safer and more effective treatments in the future.

Abstract
Rheumatoid arthritis (RA) is the most common inflammatory arthropathy, with evidence pointing to an immune-mediated etiology that propagates chronic inflammation. Although targeted immune therapeutics and aggressive treatment strategies have substantially improved, a complete understanding of the associated pathological mechanisms of the disease remains elusive. This study aimed at investigating whether regulator of G protein signaling 10 (RGS10) could affect rheumatoid arthritis (RA) pathology by regulating the immune response. A DBA/J1 mouse model of RA was established and evaluated for disease severity. RGS10 expression was inhibited by adeno-associated virus in vivo. Moreover, small interfering RNA was used to downregulate RGS10 expression in raw 264.7 cells in vitro. Results showed that RGS10 inhibition augmented RA severity, and attenuated the increase in expression of inflammatory factors. Furthermore, activated NF-κB signaling pathways were detected following RGS10 inhibition. These results revealed that RGS10 inhibition directly aggravated the RA pathological process by activating the NF-κB signaling pathway. Therefore, RGS10 is a promising novel therapeutic target for RA treatment with a potential clinical impact.

Abstract
IL-2 is a pro-inflammatory and a Th1 inducing cytokine, which is important for activation of the cell-mediated immunity. IL-2 in serum and sputum has been observed to be reduced in cystic fibrosis (CF) patients. The present IL-2 treatment study of Pseudomonas aeruginosa (PA) lung infected mice was performed in order to evaluate the effect of IL-2 supplement. One hundred-and-twenty female BALB/c mice were divided into three groups: 1) IL-2 treatment/infection (TIG), 2) non-treatment/infection (NTIG), and 3) IL-2 treatment/non-infection (TNIG). The mice were challenged intra-tracheally with PA (PAO579) embedded in seaweed alginate to resemble the biofilm mode of growth. At day 0 and 1, the treatment groups received IL-2 s.c. Mice were killed on day 1 or 2, and cytokine production, lung pathology, and quantitative lung bacteriology were estimated. IL-2 treatment of infected mice reduced the number of mice with signs of macroscopic lung pathology at day 2 (p < 0.05). The reduced macroscopic pathology was paralleled by a reduced IL-1β and TNF-α. In contrast, an increased PMN response at day 2 was observed in the IL-2 treated mice (p < 0.01). This was preceded by a significantly higher degree of microscopic inflammation at day 1 (p < 0.02). The IL-12 levels decreased in both groups of infected mice at day 2 (p < 0.01), however, significantly more in the IL-2 treated mice (p < 0.02). In accordance, but surprisingly, IFN-γ was significantly reduced in the IL-2 treated PA infected group at day 2 (p < 0.05). The present results indicate that early IL-2 treatment prolongs the PMN response but also reduces pro-inflammatory IL-1β and TNF-α and macroscopic signs of pathology.

Abstract
Regulatory B cells (Bregs) play a critical role in the control of autoimmunity and inflammation. IL-10 production is the hallmark for the identification of Bregs. However, the molecular determinants that regulate the transcription of IL-10 and control the Breg developmental program remain unknown. Here, we demonstrate that aryl hydrocarbon receptor (AhR) regulates the differentiation and function of IL-10-producing CD19+CD21hiCD24hiBregs and limits their differentiation into B cells that contribute to inflammation. Chromatin profiling and transcriptome analyses show that loss of AhR in B cells reduces expression of IL-10 by skewing the differentiation of CD19+CD21hiCD24hiB cells into a pro-inflammatory program, under Breg-inducing conditions. B cell AhR-deficient mice develop exacerbated arthritis, show significant reductions in IL-10-producing Bregs and regulatory T cells, and show an increase in T helper (Th) 1 and Th17 cells compared with B cell AhR-sufficient mice. Thus, we identify AhR as a relevant contributor to the transcriptional regulation of Breg differentiation.

Abstract
Rheumatoid arthritis (RA) is a systemic disease that affects the osteoarticular system, associated with bone fragility and increased risk of fractures. Herein, we aimed to characterize the systemic impact of the rat collagen-induced arthritis (CIA) model and explore its combination with femoral bone defect (FD). The impact of CIA on endogenous mesenchymal stem/stromal cells (MSC) was also investigated. CIA induction led to enlarged, more proliferative, spleen and draining lymph nodes, with altered proportion of lymphoid populations. Upon FD, CIA animals increased the systemic myeloid cell proportions, and their expression of co-stimulatory molecules CD40 and CD86. Screening plasma cytokine/chemokine levels showed increased tumor necrosis factor-α (TNF-α), Interleukin (IL)-17, IL-4, IL-5, and IL-12 in CIA, and IL-2 and IL-6 increased in CIA and CIA+FD, while Fractalkine and Leptin were decreased in both groups. CIA-derived MSC showed lower metabolic activity and proliferation, and significantly increased osteogenic and chondrogenic differentiation markers. Exposure of control-MSC to TNF-α partially mimicked the CIA-MSC phenotype in vitro. In conclusion, inflammatory conditions of CIA led to alterations in systemic immune cell proportions, circulating mediators, and in endogenous MSC. CIA animals respond to FD, and the combined model can be used to study the mechanisms of bone repair in inflammatory conditions.

Abstract
The aim of this analysis is to investigate the level of T cell subsets in ankylosing spondylitis (AS) and the effect of low-dose interleukin 2 (IL-2).This is a retrospective cohort study, we collected basic information, inflammatory markers, BASDAI scores, and T lymphocyte subsets of peripheral blood in patients with AS, baseline analysis, correlation analysis and comparative analysis before and after treatment were performed.Data from 73 patients (of these, 36 patients were treated with IL-2) and 85 the health were included. The absolute numbers of peripheral CD4 Treg and CD8 Treg cells were lower, while the Th17 cell number and the ratio of Th17/CD4 Treg and CD4/CD8 Treg were higher. The CD4 Treg levels and the ratio of Th17/CD4 Tregs were correlated with BASDAI. The CD4 Treg, CD8 Treg, and Th17 cells were increased after treatment with IL-2 and the ratio of Th17/CD4 Treg was decreased.Increase in ratio of Th17/CD4 Treg involved in the occurrence of AS. At the same time, low-dose IL-2 could decrease the ratio of Th17/CD4 Treg in short time, low-dose IL-2 can be used to treat autoimmune diseases to avoid adverse reactions caused by immunosuppressants. Further clinical study is needed on the efficacy of IL-2.

Abstract
IL-2 induces regulatory T cells (Tregs) and reduces disease severity, such as in graft-versus-host disease and systemic lupus erythematosus. To investigate the regulatory network of IL-2 in rheumatoid arthritis, we examined the effects of IL-2-anti-IL-2 mAb immune complexes (IL-2ICs) in a rheumatoid arthritis model of collagen-induced arthritis (CIA). CIA was induced in male DBA/1 mice by two immunizations with type II collagen at 3-wk intervals. IL-2ICs were prepared by mixing 5 μg of an anti-IL-2 mAb (clone JES6-1D) with 1 μg of mouse IL-2 and were injected i.p. every day for 3 d. Mouse paws were scored for arthritis using a macroscopic scoring system. Th1, Th2, Th17, and Tregs were analyzed by flow cytometry. Joint histopathology was examined by H&E and immunohistochemical staining. Treg functions were examined by studying in vitro suppression using flow cytometry. IL-2IC administration effectively elicited a 1.6-fold expansion of CD4+Foxp3+ Tregs in peripheral blood cells relative to that found in control mice. IL-2IC treatment significantly inhibited arthritis in CIA mice. Histopathological examination of joints revealed inhibited synovial cell proliferation and IL-17, IL-6, and TNF-α levels but increased Foxp3+ Tregs after IL-2IC treatment. Flow cytometric examination of spleen cells revealed reduced IFN-γ- and IL-17-producing cells and increased IL-10-producing Tregs after IL-2IC treatment. The suppressive activities of CD4+CD25+ Tregs induced by IL-2ICs were stronger than those in untreated mice. IL-2ICs inhibited arthritis by augmenting not only Treg numbers but also Treg functions, which play regulatory roles in autoimmune arthritis.

Abstract
OBJECTIVES Suppressor of TCR signaling-2 (STS-2) is one of the RA susceptibility genes identified in genome-wide association studies (GWAS). We tried to verify the involvement of STS-2 on the development of autoimmune arthritis in a mouse model. METHODS STS-2 knock-out (KO) and wild type (WT) mice were immunized with chicken type II collagen (CII). For CD4+ helper T cell (Th) subset analysis, intracellular cytokines in splenocytes and lymph node cells were stained and analyzed by flow cytometry. Regulatory T cell (Treg) function was analyzed by co-culturing effector CD4+T cells and Tregs collected from non-immunized mice. RESULTS CII-immunized STS-2 KO mice developed arthritis more frequently than WT mice. Although the T cell activation profile and Th subset in spleen and LNs were similar between STS-2 KO and WT mice, STS-2 KO mice showed increased IL-2-producing CD4+T cells in spleen when compared with WT mice. Accordingly, STS-2 KO CD4+T cells promoted IL-2 production by TCR stimulation. However, STS-2 KO Tregs normally suppressed T cell proliferation. CONCLUSION We proved that STS-2 is involved in the arthritis development by collagen-induced arthritis. Higher IL-2 production from STS-2 KO T cells is suggested to have a main pathogenic role in arthritis development.

Urokinase plasminogen activator and receptor promote collagen-induced arthritis through expression in hematopoietic cells. Blood Adv 2017; 1:545-556.

Abstract
The plasminogen activation (PA) system has been implicated in driving inflammatory arthritis, but the precise contribution of PA system components to arthritis pathogenesis remains poorly defined. Here, the role of urokinase plasminogen activator (uPA) and its cognate receptor (uPAR) in the development and severity of inflammatory joint disease was determined using uPA- and uPAR-deficient mice inbred to the strain DBA/1J, a genetic background highly susceptible to collagen-induced arthritis (CIA). Mice deficient in uPA displayed a near-complete amelioration of macroscopic and histological inflammatory joint disease following CIA challenge. Similarly, CIA-challenged uPAR-deficient mice exhibited significant amelioration of arthritis incidence and severity. Reduced disease development in uPA-deficient and uPAR-deficient mice was not due to an altered adaptive immune response to the CIA challenge. Reciprocal bone marrow transplant studies indicated that uPAR-driven CIA was due to expression by hematopoietic-derived cells, as mice with uPAR-deficient bone marrow challenged with CIA developed significantly reduced macroscopic and histological joint disease as compared with mice with uPAR expression limited to non-hematopoietic-derived cells. These findings indicate a fundamental role for uPAR-expressing hematopoietic cells in driving arthritis incidence and progression. Thus, uPA/uPAR-mediated cell surface proteolysis and/or uPAR-mediated signaling events promote inflammatory joint disease, indicating that disruption of this key proteolytic/signaling system may provide a novel therapeutic strategy to limit clinical arthritis.

Abstract
Background CD4+CD28− T cells exhibit autoreactive potential in autoimmune disorders, including rheumatoid arthritis (RA). It is not well known which costimulator functions as an alternative second signal in the activation of this subset after CD28 expression is downregulated. Tumor necrosis factor receptor superfamily member OX40 is a key costimulator in the activation of T cells. The aim of this study was to investigate the costimulatory effects of OX40 on CD4+CD28− T cells in autoimmune arthritis. Methods Clinical samples were collected from patients with RA and control subjects. Collagen-induced arthritis (CIA) was induced with collagen type II (CII) in DBA/1 mice. The CD4+CD28−OX40+ T-cell subset and its cytokine production were detected by flow cytometry. After T-cell purification, adoptive transfer was performed in CIA mice. The regulatory role of OX40 was determined by blocking experiments in vitro and in vivo. Results OX40 and OX40L were abnormally expressed in patients with RA and CIA mice. Further analysis showed that CD4+CD28−OX40+ T cells accumulated in patients with RA and in animal models. These cells produced higher levels of proinflammatory cytokines and were closely correlated with the clinicopathological features of the affected individuals. Adoptive transfer of CII-specific CD4+CD28−OX40+ T cells remarkably aggravated arthritic development and joint pathology in CIA mice. Moreover, OX40 blockade significantly reduced the proinflammatory responses and ameliorated arthritis development. Conclusions OX40 acts as an alternative costimulator of CD4+CD28− T cells and plays a pathogenic role in autoimmune arthritic development, suggesting that it is a potential target for immunomodulatory therapy of RA.

Abstract
Collagen-induced arthritis (CIA) is a widely used mouse model for studying inflammatory arthritis (IA). However, CIA induction protocols differ between laboratories, and direct comparison between protocol variations has not been reported. To address this issue, DBA/1 mice housed in conventional and specific-pathogen free (SPF) facilities were administered various combinations of two doses of collagen type II (CII) in complete (CFA) or incomplete Freund's adjuvant (IFA); some mice were also injected with lipopolysaccharide (LPS) and/or additional CII at specific intervals. Mice were evaluated for IA over the subsequent 2 months. Depending directly on the combination of CII, CFA, IFA, and LPS used, the incidence of IA ranged between 20%-100%, and severity extended from mild to severe even in an SPF environment. Our results demonstrate for the first time in head-to-head comparisons that specific variations in the use of CII, CFA, IFA, and LPS can induce a range of arthritic disease intensity and severity in an SPF facility. Thus, distinct experimental settings can be designed for robust assessment of factors that either exacerbate or inhibit arthritis pathogenesis. Furthermore, by achieving 100% incidence in an SPF facility, the protocols provide a practical and humane benefit by reducing the number of mice necessary for experimental assessment.

Abstract
Using the parent-into-F1 model of induced lupus and (C57BL/6 × DBA2) F1 mice as hosts, we compared the inherent lupus-inducing properties of the two parental strain CD4 T cells. To control for donor CD4 recognition of alloantigen, we used H-2(d) identical DBA/2 and B10.D2 donor T cells. We demonstrate that these two normal, nonlupus-prone parental strains exhibit two different T cell activation pathways in vivo. B10.D2 CD4 T cells induce a strong Th1/CMI pathway that is characterized by IL-2/IFN-γ expression, help for CD8 CTLs, and skewing of dendritic cell (DC) subsets toward CD8a DCs, coupled with reduced CD4 T follicular helper cells and transient B cell help. In contrast, DBA/2 CD4 T cells exhibit a reciprocal, lupus-inducing pathway that is characterized by poor IL-2/IFN-γ expression, poor help for CD8 CTLs, and skewing of DC subsets toward plasmacytoid DCs, coupled with greater CD4 T follicular helper cells, prolonged B cell activation, autoantibody formation, and lupus-like renal disease. Additionally, two distinct in vivo splenic gene-expression signatures were induced. In vitro analysis of TCR signaling revealed defective DBA CD4 T cell induction of NF-κB, reduced degradation of IκBα, and increased expression of the NF-κB regulator A20. Thus, attenuated NF-κB signaling may lead to diminished IL-2 production by DBA CD4 T cells. These results indicate that intrinsic differences in donor CD4 IL-2 production and subsequent immune skewing could contribute to lupus susceptibility in humans. Therapeutic efforts to skew immune function away from excessive help for B cells and toward help for CTLs may be beneficial.

Interleukin-2/anti-interleukin-2 monoclonal antibody immune complex suppresses collagen-induced arthritis in mice by fortifying interleukin-2/STAT5 signalling pathways. Immunology 2013; 137:305-16.

Abstract
In this study, we investigated the effects of administration of interleukin-2 (IL-2)/JES6-1 (anti-IL-2 monoclonal antibody) immune complexes on the expansion and activation of regulatory T (Treg) cells, the down-regulation of T helper type 17 (Th17) cells, and the control of the severity of collagen-induced arthritis (CIA). Wild-type and CIA-induced wild-type mice were injected intraperitoneally (i.p.) with IL-2 or IL-2/JES6-1 complex three times at 2-day intervals. Treg cell surface markers were analysed by flow cytometry. After injecting IL-2 or IL-2/JES6-1, the time kinetics of IL-2 signalling molecules was examined by FACS and Western blotting. Concentrations of IL-17 and IL-10 were measured by ELISA. Injection of IL-2/JES6-1 increased the proportion of Foxp3+ Treg cells among splenic CD4+ T cells, which reached the highest level on day 4 after injection. Up-regulation of CTLA4, GITR and glycoprotein-A repetitions predominant (GARP) was observed. Activation of p-signal transducer and activator of transcription 5 (STAT5) was apparent within 3 hr after injection of IL-2/JES6-1 complexes. Expression of IL-2 signalling molecules, including p-AKT and p-p38/mitogen-activated protein kinase, was also higher in splenocytes treated with IL-2/JES6-1 complexes. Injection of IL-2/JES6-1 complexes suppressed the induction of CIA and the production of IL-17 and inflammatory responses while increasing the level of IL-10 in the spleen. The expansion of Treg cells (via STAT5) and the concomitant increase in IL-2 signalling pathways by IL-2/JES6-1 complexes suggests their potential use as a novel therapeutic agent for the treatment of autoimmune arthritis.

Abstract
Thrombin is a positive mediator of thrombus formation through the proteolytic activation of protease-activated receptors (PARs), fibrinogen, factor XI (fXI), and other substrates, and a negative regulator through activation of protein C, a natural anticoagulant with anti-inflammatory/cytoprotective properties. Protease-engineering studies have established that 2 active-site substitutions, W215A and E217A (fII(WE)), result in dramatically reduced catalytic efficiency with procoagulant substrates while largely preserving thrombomodulin (TM)-dependent protein C activation. To explore the hypothesis that a prothrombin variant favoring antithrombotic pathways would be compatible with development but limit inflammatory processes in vivo, we generated mice carrying the fII(WE) mutations within the endogenous prothrombin gene. Unlike fII-null embryos, fII(WE/WE) mice uniformly developed to term. Nevertheless, these mice ultimately succumbed to spontaneous bleeding events shortly after birth. Heterozygous fII(WT/WE) mice were viable and fertile despite a shift toward an antithrombotic phenotype exemplified by prolonged tail-bleeding times and times-to-occlusion after FeCl₃ vessel injury. More interestingly, prothrombin(WE) expression significantly ameliorated the development of inflammatory joint disease in mice challenged with collagen-induced arthritis (CIA). The administration of active recombinant thrombin(WE) also suppressed the development of CIA in wild-type mice. These studies provide a proof-of-principle that pro/thrombin variants engineered with altered substrate specificity may offer therapeutic opportunities for limiting inflammatory disease processes.

Abstract
Active lymphocytes (LY) and macrophages (MPhi) are involved in the pathophysiology of rheumatoid arthritis (RA). Due to its anti-inflammatory effect, physical exercise may be beneficial in RA by acting on the immune system (IS). Thus, female Wistar rats with type II collagen-induced arthritis (CIA) were submitted to swimming training (6 weeks, 5 days/week, 60 min/day) and some biochemical and immune parameters, such as the metabolism of glucose and glutamine and function of LY and MPhi, were evaluated. In addition, plasma levels of some hormones and of interleukin-2 (IL-2) were also determined. Results demonstrate that CIA increased lymphocyte proliferation (1.9- and 1.7-fold, respectively, in response to concanavalin A (ConA) and lipopolysaccharide (LPS)), as well as macrophage H(2)O(2) production (1.6-fold), in comparison to control. Exercise training prevented the activation of immune cells, induced by CIA, and established a pattern of substrate utilization similar to that described as normal for these cells. Exercise also promoted an elevation of plasma levels of corticosterone (22.2%), progesterone (1.7-fold) and IL-2 (2.6-fold). Our data suggest that chronic exercise is able to counterbalance the effects of CIA on cells of the IS, reinforcing the proposal that the benefits of exercise may not be restricted to aerobic capacity and/or strength improvement.

Abstract
Follistatin-like protein-1 (FSTL-1) is a poorly characterized protein that is up-regulated in the early stage of collagen-induced arthritis and that exacerbates arthritis when delivered by gene transfer. The current study was designed to determine the mechanism by which FSTL-1 promotes arthritis. FSTL-1 was injected into mouse paws, resulting in severe paw swelling associated with up-regulation of IFN-gamma transcript and the IFN-gamma-induced chemokine, CXCL10. Mice depleted of T cells were protected. A central role for IFN-gamma was confirmed by the finding that mice deficient in IFN-gamma failed to exhibit paw swelling in response to injection of FSTL-1. Furthermore, IFN-gamma secretion from mouse spleen cells exposed to a weak TCR signal was increased 5-fold in the presence of FSTL-1. FSTL-1 could be induced by innate immune signals, including TLR4 agonists and the arthritogenic cytokine, IL-1beta, via an NFkappaB pathway. Finally, FSTL-1 was found to be overexpressed in human arthritis and its neutralization inhibited murine collagen-induced arthritis and suppressed IFN-gamma and CXCL10 production in arthritic joints. These findings demonstrate that FSTL-1 plays a critical role in arthritis by enhancing IFN-gamma signaling pathways and suggest a mechanism by which FSTL-1 bridges innate and adaptive immune responses.

Abstract
Because most cytokines are utilized, catabolized, or excreted shortly after they are produced, it has been difficult to directly measure in vivo cytokine production. Consequently, it has been necessary to infer in vivo cytokine secretion levels from the results of ex vivo assays of cytokine secretion, assays that measure tissue levels of cytokine mRNA, or assays that stain tissues for cytokine protein levels. Results of these assays provide important and useful information, but do not necessarily reflect in vivo cytokine secretion. To better determine in vivo cytokine production, the in vivo cytokine capture assay (IVCCA) was developed. IVCCA facilitates measurement of cytokines in serum by increasing their in vivo half-lives. This increases the sensitivity of measurement of in vivo cytokine production 30- to 1,000-fold. The first protocol described in this unit is for luminescence-based ELISA, while the second is for an absorbance-based method.

Abstract
Fibrin deposition within joints is a prominent feature of arthritis, but the precise contribution of fibrin(ogen) to inflammatory events that cause debilitating joint damage remains unknown. To determine the importance of fibrin(ogen) in arthritis, gene-targeted mice either deficient in fibrinogen (Fib-) or expressing mutant forms of fibrinogen, lacking the leukocyte receptor integrin alphaMbeta2 binding motif (Fibgamma390-396A) or the alphaIIbbeta3 platelet integrin-binding motif (FibgammaDelta5), were challenged with collagen-induced arthritis (CIA). Fib- mice exhibited fewer affected joints and reduced disease severity relative to controls. Similarly, diminished arthritis was observed in Fibgamma390-396A mice, which retain full clotting function. In contrast, arthritis in FibgammaDelta5 mice was indistinguishable from that of controls. Fibrin(ogen) was not essential for leukocyte trafficking to joints, but appeared to be involved in leukocyte activation events. Fib- and Fibgamma390-396A mice with CIA displayed reduced local expression of TNF-alpha, IL-1beta, and IL-6, which suggests that alphaMbeta2-mediated leukocyte engagement of fibrin is mechanistically upstream of the production of proinflammatory mediators. Supporting this hypothesis, arthritic disease driven by exuberant TNF-alpha expression was not impeded by fibrinogen deficiency. Thus, fibrin(ogen) is an important, but context-dependent, determinant of arthritis, and one mechanism linking fibrin(ogen) to joint disease is coupled to alphaMbeta2-mediated inflammatory processes.

Abstract
Proinflammatory Th1 responses are believed to be involved in the induction and perpetuation of rheumatoid arthritis. However, the role of IFN-gamma, the major cytokine produced by Th1 cells, is still incompletely defined. In the present study, we investigated the effects of IFN-gamma deficiency (IFN-gamma(-/-)) on the course of experimental murine Ag-induced arthritis (AIA). In the acute stage of disease, IFN-gamma(-/-) AIA mice showed significantly increased inflammatory responses compared with wild-type C57BL/6 AIA mice, i.e., exacerbated joint swelling, increased delayed-type hypersensitivity reaction, and increased histopathological scores of arthritis. Intraarticular administration of exogenous IFN-gamma at induction of AIA significantly suppressed these acute aggravation effects. Stimulated cells isolated from lymph nodes and spleen of IFN-gamma(-/-) AIA mice showed increased production of IL-2, IL-4, IL-5, IL-6, but most prominently of IL-17. These elevations were paralleled by decreased humoral immune responses, with low serum levels of total and Ag-specific IgG (IgG1, IgG2a(b), IgG2b, IgG3). At immunohistology, the knee joints of IFN-gamma(-/-) AIA mice showed massive neutrophil granulocyte infiltration. Treatment with mAbs neutralizing IL-17 diminished the acute inflammation. In vitro, Th cell expansion and production of IL-17 upon restimulation were effectively and dose dependently inhibited by IFN-gamma. These results clearly demonstrate that IFN-gamma has anti-inflammatory properties during the initial phase of AIA, and indicate that IFN-gamma deficiency exerts disease-promoting effects, preferentially via IL-17-modulated pathways.

Abstract
OBJECTIVE Local interaction between soluble mediators within the inflamed synovium is a key factor that governs the pathologic outcome of inflammatory arthritides. Our aim was to investigate the interplay between the Th1 lymphokine interferon-gamma (IFNgamma) and pivotal cytokines that drive rheumatoid arthritis (RA) pathology (interleukin-1beta [IL-1beta] and tumor necrosis factor alpha [TNFalpha]) in modulating inflammation and arthritis in vitro and in vivo. METHODS Monarticular antigen-induced arthritis (AIA) was initiated in IFNgamma-deficient (IFNgamma(-/-)) mice and age-matched wild-type (IFNgamma(+/+)) mice. Joint swelling was measured and histologic analysis was performed in order to assess changes in both inflammatory and degenerative parameters in vivo. In vitro, the influence of IFNgamma in regulating IL-1beta- and TNFalpha-driven CXCL8 and CCL2 production was quantified by enzyme-linked immunosorbent assay. RESULTS In murine AIA, both inflammatory and degenerative arthritis parameters were significantly exacerbated in the absence of IFNgamma. IFNgamma appeared to be a crucial factor in regulating CXCR2+ neutrophil influx in the joint. In in vitro studies using RA fibroblast-like synoviocytes, IFNgamma modulated both IL-1beta- and TNFalpha-driven chemokine synthesis, resulting in the down-regulation of CXCL8 production. CONCLUSION IFNgamma exerts antiinflammatory, chondroprotective, and antiosteoclastogenic effects in murine AIA through a mechanism that involves the regulation of chemokine synthesis and local neutrophil recruitment. These studies suggest a potential therapeutic role of modulating IFNgamma signaling in the treatment of inflammatory arthritides.

Abstract
Unmethylated CpG-oligodeoxynucleotides (ODNs) are generally thought of as potent adjuvants with considerable therapeutic potential to enhance immune responses against microbes and tumors. Surprisingly, certain so-called stimulatory CpG-ODNs strongly inhibited the effector phase of inflammatory arthritis in the K/BxN serum transfer system, either preventively or therapeutically. Also unexpected was that the inhibitory influence did not depend on the adaptive immune system cells mobilized in an immunostimulatory context. Instead, they relied on cells of the innate immune system, specifically on cross talk between CD8α+ dendritic cells and natural killer cells, resulting in suppression of neutrophil recruitment to the joint, orchestrated through interleukin-12 and interferon-γ. These findings highlight potential applications of CpG-ODNs and downstream molecules as antiinflammatory agents.

Abstract
OBJECTIVE Mesenchymal stem cells (MSCs) are precursors of tissue of mesenchymal origin, but they also have the capacity to regulate the immune response by suppressing T and B lymphocyte proliferation in a non-major histocompatibility complex-restricted manner. Use of MSCs as immunosuppressant agents in autoimmune diseases has been proposed and successfully tested in animal models. We explored the feasibility of using allogeneic MSCs as therapy for collagen-induced arthritis, a mouse model for human rheumatoid arthritis. METHODS DBA/1 mice were immunized with type II collagen in Freund's complete adjuvant, and some of the animals received an intraperitoneal injection of allogeneic MSCs. RESULTS A single injection of MSCs prevented the occurrence of severe, irreversible damage to bone and cartilage. MSCs induced hyporesponsiveness of T lymphocytes as evidenced by a reduction in active proliferation, and modulated the expression of inflammatory cytokines. In particular, the serum concentration of tumor necrosis factor alpha was significantly decreased. MSCs exerted their immunomodulatory function by educating antigen-specific Tregs. CONCLUSION Our results suggest an effective new therapeutic approach to target the pathogenic mechanism of autoimmune arthritis using allogeneic MSCs. However, further studies are required before these results can be translated to clinical settings.

Abstract
Injection of the same antigen following primary immunization induces a classic secondary response characterized by a large quantity of high-affinity antibody of an immunoglobulin G class produced more rapidly than in the initial response - the products of memory B cells are qualitatively distinct from that of the original naive B lymphocytes. Very little is known of the help provided by the CD4 T cells that stimulate memory B cells. Using antigen-specific T-cell receptor transgenic CD4 T cells (DO11.10) as a source of help, we found that naive transgenic T cells stimulated memory B cells almost as well (in terms of quantity and speed) as transgenic T cells that had been recently primed. There was a direct correlation between serum antibody levels and the number of naive transgenic T cells transferred. Using T cells from transgenic interleukin-2-deficient mice we showed that interleukin-2 was not required for a secondary response, although it was necessary for a primary response. The results suggested that the signals delivered by CD4 T cells and required by memory B cells for their activation were common to both antigen-primed and naive CD4 T cells.

Abstract
Polyarthritis in the presence of a cutaneous T-cell lymphoma is a rare phenomenon. We describe a case of mycosis fungoides with development of a symmetric erosive polyarthritis of the small hand joints and feet, diagnosed as rheumatoid arthritis. An identical monoclonal T-cell population in the skin and in the synovium was detected by T-cell receptor gene rearrangement analysis, illustrating articular dissemination of lymphoma cells. Differentiating mycosis fungoides-associated arthritis from rheumatoid arthritis may have important implications for treatment. Based on this case, the relevant literature, and the newest disease concepts, pathogenic mechanisms and therapeutic options of mycosis fungoides-associated arthritis are discussed.

Abstract
OBJECTIVE Heme oxygenase 1 (HO-1) can be induced by inflammatory mediators as an adaptive response. The objective of the present study was to determine the consequences of HO-1 modulation in the murine collagen-induced arthritis (CIA) model. METHODS DBA/1J mice were treated with an inhibitor of HO-1, tin protoporphyrin IX (SnPP), or with an inducer of HO-1, cobalt protoporphyrin IX (CoPP), from day 22 to day 29 after CIA induction. The clinical evolution of disease was monitored visually. At the end of the experiment, joints were examined for histopathologic changes. Cytokine levels in paws were measured by enzyme-linked immunosorbent assay. Levels of HO-1, cyclooxygenase 2 (COX-2), and prostaglandin E2 (PGE2) were determined. Effects of treatments on the early phase of disease and after prophylactic administration were also assessed. RESULTS CoPP strongly induced HO-1, resulting in the inhibition of cartilage erosion accompanied by extensive fibrosis in the joint. Levels of tumor necrosis factor alpha (TNFalpha), interleukin-2 (IL-2), and IL-10 were inhibited by CoPP, whereas levels of vascular endothelial growth factor were increased. Treatment with SnPP significantly reduced the severity of CIA, with inhibition of joint inflammation and cartilage destruction. The levels of PGE2, IL-1beta, and TNFalpha were also significantly reduced by SnPP treatment, which did not modify COX-2 protein expression. SnPP was more effective than CoPP in preventing the development of CIA (prophylactic administration). CONCLUSION HO-1 is induced during CIA. Although overexpression of this protein causes some beneficial effects, strategies aimed at HO-1 overexpression cannot slow the progression of the chronic inflammatory disease, whereas treatment with SnPP, which inhibits HO-1, exerts prophylactic and therapeutic effects.

Abstract
OBJECTIVE To further investigate the effects of interleukin-1 (IL-1) in immune-mediated joint inflammation, we examined the role of IL-2, Th1 interferon-gamma (IFNgamma), and Th2 (IL-4) cytokines, joint macrophages, and macrophage-derived cytokines (IL-12 p40, IL-6, leukemia inhibitory factor [LIF], oncostatin M [OSM], and granulocyte-macrophage colony-stimulating factor [GM-CSF]) in a CD4+ T lymphocyte-dependent model of acute arthritis. METHODS Methylated bovine serum albumin (mBSA)/IL-1-induced arthritis was elicited in wild-type, gene-knockout, and monoclonal antibody-treated mice. Synovial lining macrophages were selectively depleted by intraarticular injection of clodronate liposomes prior to disease induction. The severity of arthritis was assessed histologically. RESULTS Mice deficient in IL-2 were almost completely protected from arthritis, and neutralization of IL-4 reduced the severity of disease. In contrast, arthritis severity and resolution appeared to be independent of IFNgamma. Synovial lining macrophage depletion markedly reduced arthritis severity. IL-6 or LIF deficiency was only modestly protective, although as previously reported, GM-CSF deficiency conferred profound disease resistance. IL-12 p40-deficient mice (which lack IL-12 and IL-23) and OSM receptor-deficient mice were susceptible to mBSA/IL-1-induced arthritis. CONCLUSION Acute mBSA/IL-1-induced arthritis is dependent on IL-2 and IL-4, but not IFNgamma. In vivo, the Th1/Th2 paradigm may be distorted by the presence of macrophage-derived cytokines such as IL-1. Synovial lining macrophages are essential in mBSA/IL-1-induced arthritis. However, the requirement for macrophage-derived cytokines is selective; that is, IL-6, LIF, and especially GM-CSF are necessary, but IL-12, IL-23, and OSM are dispensable. IL-1 may therefore influence both adaptive and innate immune mechanisms in acute inflammatory arthritis.

Abstract
Th cell differentiation from naive precursors is a tightly controlled process; the most critical differentiation factor is the action of the driving cytokine: IL-12 for Th1 development, IL-4 for Th2 development. We found that CD4(+) T cells from nonobese diabetic mice spontaneously differentiate into IFN-gamma-producing Th1 cells in response to polyclonal TCR stimulation in the absence of IL-12 and IFN-gamma. Instead, IL-2 was necessary and sufficient to direct T cell differentiation to the Th1 lineage by nonobese diabetic CD4(+) T cells. Its ability to direct Th1 differentiation of both naive and memory CD4(+) T cells was clearly uncoupled from its ability to stimulate cell division. Autocrine IL-2-driven Th1 differentiation of nonobese diabetic T cells may represent a genetic liability that favors development of IFN-gamma-producing autoreactive T cells.

Abstract
We have previously shown that oral administration of skimmed milk(SM) fermented with Lactobacillus delbrueckii ssp. bulgaricus OLL1073R-1 (OLL1073R-1/SM) to DBA/1 mice inhibited the development of collagen-induced arthritis (CIA). In this study, our aim was to examine possible mechanisms of inhibiting the development of CIA. We studied the effect of OLL1073R-1/SM on cytokine secretion from cells of popliteal lymph nodes (lymph node cells; LNC) of mice. The results showed that feeding OLL1073R-1/SM inhibited secretion of proinflammatory cytokines such as interferon gamma (IFN-gamma), interleukin 6 (IL-6), tumor necrosis factor alpha (TNF-alpha) and the chemokine, monocyte chemoattractant protein 1 (MCP-1). The most prominent effect was inhibition of TNF-alpha. Secretion of IL-2 and IL-4 were not influenced. Feeding OLL1073R-1/SM inhibited secretion of proinflammatory cytokines produced by accessory cells, but not T cells. We conclude that CIA may be prevented via down regulation of secretion of proinflammatory cytokines such as IL-6, TNF-alpha and IFN-gamma, and of the chemokine of MCP-1.

Abstract
The exacerbation of pre-existing autoimmune diseases is a potential toxic effect of immunoactive drugs. An increase in the incidence of autoimmune thyroiditis has been noted in patients treated with human recombinant interleukin-2 (rIL-2). In contrast, human rIL-2 tends to protect mice from autoimmunity. As the effects of murine rIL-2 on autoimmunity have not been reported in mice, lupus-prone female (NZBxNZW) F1 mice were treated with 20,000 IU murine rIL-2 intraperitoneally, twice weekly for 13 weeks, beginning at 15 weeks of age. No evidence of an exacerbating effect of murine IL-2 on the lupus disease of (NZBxNZW) F1 mice was observed as no change in the following parameters were seen, namely mean survival time, mean body weight, anti-DNA and antinuclear antibody production. These results show that: 1) like human rIL-2, murine rIL-2 does not exacerbate autoimmunity in mice; 2) the biological effects of human as well as murine rIL-2 in mice differ from those seen with human rIL-2 in man. These latter findings suggest that the selection of the relevant animal species for immunotoxicity studies with recombinant cytokines and derivatives may be less straightforward than previously thought.

Abstract
This study was designed to test the process of selecting encephalitogenic T cell lines in the Lewis rat using recombinant human IL-2 (rhIL-2) in comparison to TCGF. The lines were tested for growth, antigen induced proliferation, cytokine production, V-beta 8.2 expression and pathogenicity. We now report that rhIL-2 and TCGF were equally effective in supporting short-term pathogenic T-cell lines with similar proportion of V-beta 8.2 usage. For the maintenance of long term lines, however, TCGF was superior to IL-2. The concentration of rhIL-2 influenced the cultures: 10 units/ml led to more T-cell proliferation than either 2 or 50 units/ml. However, 50 units/ml of IL-2 led to enhanced Th1 polarization. Thus, the type and concentration of growth factors can influence both the propagation of T cells and their phenotype.

Abstract
We have recently found that matrix metalloproteinases (MMPs) are targets for T-cell and B-cell reactivity in experimental arthritis. In the present article, we investigate whether modulation of MMP-specific T-cell responses could influence the course of adjuvant arthritis (AA). Lewis rats were treated nasally with MMP peptides prior to or after AA induction. Administration of the MMP-10 or the MMP-16 peptide prior to AA induction reduced the arthritic symptoms. In contrast, administration of the MMP-10 peptide after AA induction aggravated the arthritic symptoms. The present study shows the possible usefulness of MMP peptides for immunotherapy. However, a clear understanding of proper timing of peptide administration is crucial for the development of such therapies.

Abstract
Interleukin-2 is an immunotherapeutic agent for the treatment of metastatic tumors. Administration of recombinant human IL-2 (rhIL-2) in vivo activates lymphocytes and cell-mediated immune responses. In mice, we have recently observed a dramatic increase of serum IFN-gamma levels in response to in vivo administration of rhIL-2, which was necessary for the observed protective effects of IL-2 against the development of collagen-induced arthritis. To explore further the basis of this phenomenon, the kinetics and source of IFN-gamma in response to IL-2 was investigated. Highest serum levels of IFN-gamma were observed within 3 h of IL-2 administration, with levels decreasing over time. Anti-IL-2 receptor beta antibody blocked this IFN-gamma induction. Multiple doses of rhIL-2 resulted in corresponding increases in circulating IFN-gamma. IFN-gamma induction was dose-dependent between doses of 240 to 30,000 U of rhIL-2. Analysis of the cellular source of IFN-gamma secretion using NK- and T cell-deficient mice demonstrated that NK cells are the likely source of IFN-gamma. Furthermore, IFN-gamma secretion in response to IL-2 administration was not affected by the absence of IL-12, the pivotal cytokine for determination of Th1 responses. These results suggest that effects of IL-2 on immune responses in vivo may be mediated by IFN-gamma.

Abstract
CD4+ T cells are believed to play a central role in the initiation and perpetuation of autoimmune diseases such as multiple sclerosis. In the murine model for multiple sclerosis, experimental autoimmune encephalomyelitis, pathogenic T cells exhibit a Th1-like phenotype characterized by heightened expression of proinflammatory cytokines. Systemic administration of "regulatory" cytokines, which serve to counter Th1 effects, has been shown to ameliorate autoimmune responses. However, the inherent problems of nonspecific toxicity limit the usefulness of systemic cytokine delivery as a potential therapy. Therefore, we used the site-specific trafficking properties of autoantigen-reactive CD4+ T cells to develop an adoptive immunotherapy protocol that provided local delivery of a Th1 cytokine antagonist, the p40 subunit of IL-12. In vitro analysis demonstrated that IL-12 p40 suppressed IFN-gamma production in developing and effector Th1 populations, indicating its potential to modulate Th1-promoted inflammation. We have previously demonstrated that transduction of myelin basic protein-specific CD4+ T cells with pGC retroviral vectors can result in efficient and stable transgene expression. Therefore, we adoptively transferred myelin basic protein-specific CD4+ T cells transduced to express IL-12 p40 into mice immunized to develop experimental autoimmune encephalomyelitis and demonstrated a significant reduction in clinical disease. In vivo tracking of bioluminescent lymphocytes, transduced to express luciferase, using low-light imaging cameras demonstrated that transduced CD4+ T cells trafficked to the central nervous system, where histological analysis confirmed long-term transgene expression. These studies have demonstrated that retrovirally transduced autoantigen-specific CD4+ T cells inhibited inflammation and promoted immunotherapy of autoimmune disorders.

Abstract
Production of cytokines (CKs) in the tumor micro-environment may modulate tumor-host interactions. However, pre-clinical models often provide conflicting data and there is no established role for CKs as modulators of the natural or treatment-related behavior of tumors. Serial sampling by fine-needle aspirates (FNAs) of identical metastases from patients affected with metastatic melanoma and undergoing IL-2-based vaccination allowed prospective measurement of IL-10, TGF-beta1, TGF-beta2 and IFN-gamma transcriptional levels assessed by quantitative real-time PCR. Thus, it was possible to prospectively document the expression of markers relevant to a given treatment and follow at the same time the clinical outcome of the lesions left in place. Eight of 27 metastatic lesions completely regressed in response to the treatment and 1 demonstrated >50% shrinkage. These regressions occurred after the follow-up FNA had been obtained. IL-10 transcript was differentially expressed in pre-treatment FNA of responding lesions (t-test p(2) = 0.002). During treatment, INF-gamma transcript levels significantly increased in regressing compared to non-regressing lesions (t-test p(2) = 0.03). These data suggest that the pre-treatment CK profile of the tumor micro-environment may determine clinical responsiveness to immune therapy. Furthermore, temporal changes in CK expression during treatment might describe the biological characteristics of an effective immune response.
