Abstract
The aim of this study was to investigate potentialities of poly(dl-lactide-co-glycolide) (PLGA) microspheres for the delivery of small interfering RNAs (siRNAs) against tumor necrosis factor α (TNF-α) to achieve prolonged and efficient inhibition of TNF-α for the treatment of rheumatoid arthritis (RA). PLGA microspheres were prepared by a modified multiple emulsion-solvent evaporation method. The formulations were characterized in terms of morphology, mean diameter and siRNAs distribution, encapsulation efficiency, and in vitro release kinetics. The efficiency of this system was then evaluated both in vitro and in vivo using the murine monocytic cell line J774 and a pre-clinical model of RA, respectively. siRNA-encapsulating PLGA microspheres were characterized by a high encapsulation efficiency and a slow and prolonged anti-TNF-α siRNAs. Our results provide evidence that, upon intra-articular administration, PLGA microspheres slowly releasing siRNAs effectively inhibited the expression of TNF-α in arthritic joints. Our system might represent an alternative strategy for the design of novel anti-rheumatic therapies based on the use of RNA interference in RA.

Abstract
The development of novel treatments for rheumatoid arthritis (RA) requires the interplay between clinical observations and studies in animal models. Given the complex molecular pathogenesis and highly heterogeneous clinical picture of RA, there is an urgent need to dissect its multifactorial nature and to propose new strategies for preventive, early and curative treatments. Research on animal models has generated new knowledge on RA pathophysiology and aetiology and has provided highly successful paradigms for innovative drug development. Recent focus has shifted towards the discovery of novel biomarkers, with emphasis on presymptomatic and emerging stages of human RA, and towards addressing the pathophysiological mechanisms and subsequent efficacy of interventions that underlie different disease variants. Shifts in the current paradigms underlying RA pathogenesis have also led to increased demand for new (including humanised) animal models. There is therefore an urgent need to integrate the knowledge on human and animal models with the ultimate goal of creating a comprehensive 'pathogenesis map' that will guide alignment of existing and new animal models to the subset of disease they mimic. This requires full and standardised characterisation of all models at the genotypic, phenotypic and biomarker level, exploiting recent technological developments in 'omics' profiling and computational biology as well as state of the art bioimaging. Efficient integration and dissemination of information and resources as well as outreach to the public will be necessary to manage the plethora of data accumulated and to increase community awareness and support for innovative animal model research in rheumatology.

Abstract
MicroRNAs (miRNAs) are small noncoding RNA molecules that negatively regulate gene expression at the post-transcriptional level. Currently, there are 939 mature human miRNA sequences listed in the Sanger updated miRNA registry. There are approximately 1500 predicted miRNAs in the human genome that may regulate the expression of one third of our genes. By controlling the accumulation of the target protein(s) in cells, these regulatory RNA molecules participate in key functions in many physiological networks and their deregulation has been implicated in the pathogenesis of serious human disorders, such as cancer and infection. The implication of miRNAs in immune-mediated disorders such as rheumatoid arthritis (RA) has recently emerged suggesting that miRNA-based therapeutic approaches may have a promising potential in these diseases. Here, we provide an overview of the state-of-the-art on miRNAs in RA, focusing on both systemic and local features of the pathology.

Abstract
Biomarkers are indicators of biological conditions that can be detected and measured in body fluids or tissues. Biomarkers can be detectable before the clinical onset of the disease, and are thus useful for prognosis; they can be measured at early stages of the disease and are useful for stratification and classification of the disease and patients; they can be monitored along the disease course and used as indicators of risk factors and pharmacological response to treatment. Ideally, biomarkers should be sensitive, specific, have high predictive power, and be easily accessible. Rheumatoid arthritis (RA) is the most frequent chronic inflammatory disorder, affecting millions of people worldwide and leading to joint damage and substantial morbidity. RA is a heterogeneous disorder with a fluctuating clinical course and unpredictable prognosis. And although a large panel of biologics is available to clinicians, the main challenge remains to treat patients as early as possible with the most personalised therapy. Today, the most challenging issue in RA is the identification of biomarkers for early disease diagnosis and for prediction of drug response. Among molecules that can fulfil this expectation, micro(mi)-RNAs certainly represent an option. The potential value of miRNAs as a novel class of biomarkers is well documented in cancer. Moreover, the presence and stability of miRNAs in body fluids provide fingerprints that can serve as molecular biomarkers for disease diagnosis and therapeutic outcome. As a growing body of evidences reveals abnormal expression of specific miRNAs in RA tissues, the use of a blood-based miRNA signature for optimal diagnosis and treatment becomes a realistic option.

Abstract
Several molecules have been identified as critical mediators of chronic inflammation in immune system-mediated disorders such as rheumatoid arthritis (RA), and biological therapies targeting these molecules have been developed during the past two decades. Compared with conventional therapies, anti-TNF biotherapies have greatly improved the treatment of patients with RA, and several biological agents with distinct mechanisms of action are under development. Despite significant advances in this field, unmet medical needs remain. RA is the prototype disease for the evaluation of targeted therapies, and various novel genes have been described as being critically involved in disease pathogenesis. Thus, a novel area of research has recently emerged in the field of RA therapy, involving the genetic screening and validation of novel candidates in vivo using RNAi. Among the vehicles for the efficient targeting of macrophages, which play a critical role in disease chronicity, cationic liposomes represent the most promising option for the safe and specific use of RNAi in vivo. This review discusses the role of cationic liposomes as a mechanism for the systemic administration of siRNAs in the validation of RA therapeutic targets.

Abstract
PURPOSE To evaluate the effect of adeno-associated virus (AAV) vector-mediated viral (v)IL-10 gene expression on lacrimal gland (LG) immunopathology and ocular surface disease in a rabbit model of induced autoimmune dacryoadenitis (ID). METHODS Autologous peripheral blood lymphocytes, activated in a mixed-cell reaction when cocultured with purified rabbit lacrimal epithelial cells, induce a Sjögren's-like autoimmune dacryoadenitis when injected directly back into the donor animal's inferior LG. Four weeks after disease induction, AAV vector expressing the vIL-10 gene under control of a tetracycline-inducible promoter was injected into the inferior LG of the treatment group (ID/Rx), and doxycycline was fed orally to induce transgene expression. The ID group serving as control also received doxycycline. All LGs were removed 16 weeks after disease induction. RESULTS Clinical symptoms showed overall improvement in the ID/Rx group compared with the ID group. Histopathologic examination of the ID group's LG revealed scattered large lymphocytic foci and areas of altered or distorted acini, whereas the ID/Rx group had scattered small lymphocytic foci. The number of CD18(+) cells was almost fivefold lower in the ID/Rx group than in the ID group. Although the total number of RTLA(+) cells did not differ between the groups, the CD4/CD8 ratio was 16-fold smaller in the ID/Rx group. CONCLUSIONS Animals with experimentally induced autoimmune dacryoadenitis appeared to benefit from AAV-mediated vIL-10 gene transfer therapy. Quantitative immunohistochemical analysis suggested that the therapy might not have been simply immunosuppressive but rather supported the induction of CD8(+) regulatory cells.

Abstract
The regeneration of bone tissue depends on the concerted actions of a plethora of signals that recruit mesenchymal stem cells for lineage-specific differentiation, with cellular phenotypes serving various functions throughout their life span. The signals are conveyed in hormones, growth factors, and mechanical forces, all of which ensure proper modeling and remodeling. Both processes are secured by indigenous and programmed metabolism in osteoblasts/osteocytes as well as in other stem cell (SC)-derived cell types (e.g., osteoclasts, bone lining cells) involved in the remodeling of the subject tissue. The focus of this review is the concerted action of these signals as well as the regulatory and/or stabilizing control circuits exhibited by a class of small RNAs, designated microRNAs. We discuss an in vitro approach for ensuring proper phenotype acquisition as well as the choice of scaffolds and animal models for in vivo tissue repair. This approach includes selection of SC niches to optimize bone formation in vivo, transcription factors important for osteoblastogenesis, the Wnt and Notch pathways of signaling, selection of delivery systems for gene therapy, use of appropriate matrices and scaffolds, in vivo mechanostimulation, choice of lesions to be repaired, and type of animal to use. We also discuss Wnt-related and SC-based treatment of osteoporosis. Throughout, we offer considerations for the selection of model systems and parameters to assess the entire procedure from initial SC selection to final bone repair, and conclude with a table summarizing our recommendations.

Abstract
BACKGROUND RNA interference (RNAi) is a powerful endogenous process initiated by short double-stranded RNAs, which results in sequence-specific posttranscriptional gene silencing. The possibility of blocking the expression of any protein carries huge expectations for potential therapeutic applications in a wide range of diseases. For clinical development, however, the use of RNAi-based therapeutics has to overcome major obstacles, mainly targeted delivery and safety issues. OBJECTIVE/METHODS In this short review, we provide an overview of specifications for RNAi-based gene therapy in rheumatoid arthritis (RA) and discuss recent progresses in the development of efficient silencing, focusing on expression of short hairpin RNAs. RESULTS/CONCLUSIONS Combining advances in RNAi methodology with gene therapy technology opens avenues for rapid applications to RA.

Abstract
BACKGROUND Micro RNAs are small, non-coding, single-stranded RNAs that negatively regulate gene expression at the post-transcriptional level. Since miR-143 was found to be down-regulated in prostate cancer cells, we wanted to analyze its expression in human prostate cancer, and test the ability of miR-43 to arrest prostate cancer cell growth in vitro and in vivo. RESULTS Expression of miR-143 was analyzed in human prostate cancers by quantitative PCR, and by in situ hybridization. miR-143 was introduced in cancer cells in vivo by electroporation. Bioinformatics analysis and luciferase-based assays were used to determine miR-143 targets. We show in this study that miR-143 levels are inversely correlated with advanced stages of prostate cancer. Rescue of miR-143 expression in cancer cells results in the arrest of cell proliferation and the abrogation of tumor growth in mice. Furthermore, we show that the effects of miR-143 are mediated, at least in part by the inhibition of extracellular signal-regulated kinase-5 (ERK5) activity. We show here that ERK5 is a miR-143 target in prostate cancer. CONCLUSIONS miR-143 is as a new target for prostate cancer treatment.

Abstract
Bone and cartilage are being generated de novo through concerted actions of a plethora of signals. These act on stem cells (SCs) recruited for lineage-specific differentiation, with cellular phenotypes representing various functions throughout their life span. The signals are rendered by hormones and growth factors (GFs) and mechanical forces ensuring proper modelling and remodelling of bone and cartilage, due to indigenous and programmed metabolism in SCs, osteoblasts, chondrocytes, as well as osteoclasts and other cell types (eg T helper cells).This review focuses on the concerted action of such signals, as well as the regulatory and/or stabilizing control circuits rendered by a class of small RNAs, designated microRNAs. The impact on cell functions evoked by transcription factors (TFs) via various signalling molecules, also encompassing mechanical stimulation, will be discussed featuring microRNAs as important members of an integrative system. The present approach to cell differentiation in vitro may vastly influence cell engineering for in vivo tissue repair.

Abstract
Prostate cancer metastasis to bone results in mixed osteolytic and osteoblastic lesions associated with high morbidity, and there is mounting evidence that the urokinase-type plasminogen system is causatively involved in the progression of prostate cancer. Adult mesenchymal stem cells (MSCs) are promising tools for cell-mediated gene therapy with the advantage of osteogenic potential, a critical issue in the case of osteolytic metastases. In this study, we evaluated the therapeutic use of engineered murine MSCs for in vivo delivery of the urokinase-type plasminogen antagonist amino-terminal fragment (hATF) to impair osteolytic prostate cancer cell progression in bone and to repair bone lesions. Bioluminescence imaging revealed that both primary MSCs and the MSC line C3H10T1/2 (C3) expressing hATF (MSC-hATF) significantly inhibited intratibial PC-3 Luciferase (Luc) growth following coinjection in SCID mice. Furthermore, microcomputed tomography imaging of vascular network clearly demonstrated a significant decrease in tumor-associated angiogenesis and a protection from tumor-induced osteolysis in MSC-hATF-treated mice. Importantly, the osteogenic potential of MSC-hATF cells was unaffected, and an area of new bone formation was evidenced in 60% of animals. Together, these data support the concept of MSC-based therapy of tumor osteolysis disease, indicating that MSCs may combine properties of vehicle for angiostatic agent with osteogenic potential. Disclosure of potential conflicts of interest is found at the end of this article.

Abstract
BACKGROUND Anti-inflammatory gene therapy is promising in inflammatory diseases such as rheumatoid arthritis (RA). We have previously demonstrated that intra-muscular (i.m.) electrotransfer (ET) of plasmids encoding three different human tumor necrosis factor-alpha-soluble receptor I variants (hTNFR-Is) exert protective effects in an experimental RA model. However, such a systemic approach could be responsible for side effects. The present study aimed at performing an intra-articular (i.a.) gene therapy by electrotransfer using the hTNFR-Is plasmids. METHODS AND RESULTS We evaluated targeting of mice joints by CCD optical imaging after i.a. ET of a luciferase-encoding plasmid and we showed that ET led to strongly increased transgene expression in a plasmid dose-dependent manner. Moreover, articular and seric hTNFR-Is was detectable for 2 weeks. As expected, systemic hTNFR-Is rates were lower after i.a. ET than after i.m. ET. A longer protein secretion could be achieved with several i.a. ETs. Also, we observed that hTNFR-Is expression within arthritic joints was slightly higher than in normal joints. CONCLUSIONS In collagen-induced arthritis (CIA), a mouse model for RA, we demonstrated that hTNFR-Is/mIgG1-encoding plasmid i.a. ET decreased joint destruction in the ankles. In conclusion, our results suggest that local TNFR-Is gene therapy may play a role in decreasing joint destruction in CIA.

Abstract
In order to ensure that MSCs designed for in vivo cartilage repair do not untowardly differentiate into osteoblasts and mineralize in situ, we tested whether siRNA-induced suppression of cbfa1/Runx2 affected the osteogenic and chondrogenic differentiation potential of the murine cell line C3H10T1/2. Anti-cbfa1/Runx2 siRNA decreased the levels of cbfa1/Runx2 mRNA and protein by 65-80%, and also markedly reduced the expression of osteoblast-related genes such as Dlx5, osterix, collagen type I, alkaline phosphatase (AP), osteocalcin, SPARC/osteonectin and osteopontin, leading to a temporal expression of AP enzyme activity and mineralization potential delayed by at least some 7-9 days. Furthermore, siRNA-transfected cells, grown under chondrogenic conditions did not display biologically significant changes in the expression of aggrecan, collagen type II or type X, or histology when grown in micropellets or monolayer cultures. Finally, when cells were propagated in osteogenic medium and injected into the tibial muscles of SCID mice, no overtly mineralized bone tissue emerged. These experiments indicate that a major transient reduction of cbfa1/Runx2 expression in MSCs is sufficient to delay osteoblastic differentiation, both in vitro and in vivo, while chondrogenesis seemed to be sustained.

Abstract
Chondrogenesis is a process involving stem-cell differentiation through the coordinated effects of growth/differentiation factors and extracellular matrix (ECM) components. Recently, mesenchymal stem cells (MSCs) were found within the cartilage, which constitutes a specific niche composed of ECM proteins with unique features. Therefore, we hypothesized that the induction of MSC differentiation towards chondrocytes might be induced and/or influenced by molecules from the microenvironment. Using microarray analysis, we previously identified genes that are regulated during MSC differentiation towards chondrocytes. In this study, we wanted to precisely assess the differential expression of genes associated with the microenvironment using a large-scale real-time PCR assay, according to the simultaneous detection of up to 384 mRNAs in one sample. Chondrogenesis of bone-marrow-derived human MSCs was induced by culture in micropellet for various periods of time. Total RNA was extracted and submitted to quantitative RT-PCR. We identified molecules already known to be involved in attachment and cell migration, including syndecans, glypicans, gelsolin, decorin, fibronectin, and type II, IX and XI collagens. Importantly, we detected the expression of molecules that were not previously associated with MSCs or chondrocytes, namely metalloproteases (MMP-7 and MMP-28), molecules of the connective tissue growth factor (CTGF); cef10/cyr61 and nov (CCN) family (CCN3 and CCN4), chemokines and their receptors chemokine CXC motif ligand (CXCL1), Fms-related tyrosine kinase 3 ligand (FlT3L), chemokine CC motif receptor (CCR3 and CCR4), molecules with A Disintegrin And Metalloproteinase domain (ADAM8, ADAM9, ADAM19, ADAM23, A Disintegrin And Metalloproteinase with thrombospondin type 1 motif ADAMTS-4 and ADAMTS-5), cadherins (4 and 13) and integrins (alpha4, alpha7 and beta5). Our data suggest that crosstalk between ECM components of the microenvironment and MSCs within the cartilage is responsible for the differentiation of MSCs into chondrocytes.

Abstract
Rheumatoid arthritis is a chronic autoimmune disease of unknown etiology that is characterized by chronic systemic inflammation, mainly affecting the joints, leading to subsequent destruction of the cartilage and bone. RNA interference (RNAi) has been used as a remarkable new research tool to control gene expression and is ultimately envisioned to be useful in clinical treatments. The potential application of RNAi-based therapy in rheumatoid disorders is evaluated. The first successful attempts at TNFalpha silencing by local and systemic delivery of small interfering RNA in experimental arthritic models are discussed. In addition, RNAi and current biotherapies used in the clinic are compared and contrasted.

Abstract
BACKGROUND The tumor necrosis factor (TNF)-alpha plays a central role in rheumatoid arthritis (RA) and current biotherapies targeting TNF-alpha have a major impact on RA treatment. The long-term safety concerns associated with the repetitive TNF blockade prompt optimization of therapeutic anti-TNF approaches. Since we recently demonstrated that intra-articular gene transfer using a recombinant adeno-associated virus serotype 5 (rAAV5) efficiently transduces arthritic joints, we evaluate its effect on collagen-induced arthritis (CIA) when encoding TNF antagonists. METHODS Recombinant AAV5 vectors encoding the human TNFRp55 extracellular domain fused to the Fc region of mice IgG1 (TR1) or a small molecular weight dimeric human TNFRp75 extracellular domain (TR2), under two different promoters, the CMV or a chimeric NF-kappaB-based promoter inducible by inflammation, were injected into mouse CIA joints. RESULTS Best protection against arthritis was obtained with the rAAV5 encoding the TR1, as reflected by delayed disease onset, decreased incidence and severity of joint damage. This effect was associated with a transient expression of the anti-TNF agent when expressed under a NF-kappaB-responsive promoter, only detectable during disease flare, while the antagonist expression was rapidly increased and stable when expressed from a CMV promoter. Importantly, using the intra-articular administration of the rAAV5-NF-kappaB-TR1 vector, we observed a striking correlation between local TR1 expression and inflammation. CONCLUSIONS These findings strongly support the feasibility of improving the safety of anti-TNF approaches for the treatment of arthritis by local rAAV5-mediated gene expression under an inflammation-responsive promoter, able to provide a limited, transient and therapeutically relevant expression of anti-TNF compounds.

Abstract
Dendritic cells (DCs) are professional APCs which have the unique ability to present both foreign and self-Ags to T cells and steer the outcome of immune responses. Because of these characteristics, DCs are attractive vehicles for the delivery of therapeutic vaccines. Fully matured DCs are relatively well-defined and even used in clinical trials in cancer. DCs also have the potential to influence the outcome of autoimmunity by modulating the underlying autoimmune response. To gain a better appreciation of the abilities and mechanisms by which immunomodulatory DCs influence the outcome of T cell responses, we studied several immunomodulatory DCs (TNF-, IL-10-, or dexamethasone-stimulated bone marrow-derived DCs) side by side for their ability to modulate T cell responses and autoimmune diseases. Our data show that these differentially modulated DCs display a different composition of molecules involved in T cell activation. Although, all DC subsets analyzed were able to inhibit the induction of collagen-induced arthritis, the modulation of the underlying immune response was different. Vaccination with TNF- or IL-10-modulated DCs altered the Th1/Th2 balance as evidenced by the induction of IL-5- and IL-10-secreting T cells and the concomitant reduction of the IgG2a-IgG1 ratio against the immunizing Ag. In contrast, DCs modulated with dexamethasone did not affect the ratio of IL-5-producing vs IFN-gamma-producing T cells and tended to affect the Ab response in a nonspecific manner. These data indicate that distinct mechanisms can be used by distinct DC subsets to change the outcome of autoimmunity.

Abstract
Mesenchymal stem cells (MSC) are of particular interest for their potential clinical use in tissue engineering as well as for their capacity to reduce the incidence and severity of graft-versus-host disease in allogeneic transplantation. We have previously shown that MSC-mediated immune suppression acts via the secretion of soluble factor(s) induced upon stimulation. The aim of this study was to identify the molecule(s) involved and the underlying mechanism(s). We show that murine MSC secrete high levels of interleukin (IL)-6 and vascular endothelial growth factor, which are directly correlated to the inhibition of T-cell proliferation. The T-cell activation is partially restored upon addition of a neutralizing anti-IL-6 antibody or the prostaglandin E2 inhibitor indomethacin. Interestingly, no indoleamine 2,3-dioxygenase activity was detected in our conditions. Instead, we show that MSC reduce the expression of major histocompatibility complex class II, CD40, and CD86 costimulatory molecules on mature dendritic cells (DC), which was responsible for a decrease in T-cell proliferation. Moreover, we show that the differentiation of bone marrow progenitors into DC cultured with conditioned supernatants from MSC was partly inhibited through the secretion of IL-6. Altogether, these data suggest that IL-6 is involved in the immunoregulatory mechanism mediated by MSC through a partial inhibition of DC differentiation but is probably not the main mechanism. Disclosure of potential conflicts of interest is found at the end of this article.

Abstract
Prostate cancer (CaP) cells possess high affinity for bone marrow and predilection to induce bone metastasis. Although the end result of metastasis is predominantly osteoblastic, most patients present mixed lesions with osteolytic component which could initiate and precede bone formation. A precise characterization of tumor-induced bone resorption is thus necessary for early evaluation of therapeutic efficiency. Herein, we investigate the advantage of combining micro-computed tomography (microCT) and in vivo bioluminescence imaging (BLI) to determine the kinetics of the intraosseous CaP growth and bone lesions appearance in an experimental murine model. To mimic established osteolytic bone metastasis, the left tibiae of SCID mice were injected with the human CaP cell line PC-3 expressing luciferase (PC-3 Luc). Noninvasive monitoring of tumor progression was followed weekly by BLI during 4 weeks and bone morphometric parameters were quantified by microCT. Data were compared with conventional radiological and histological analyses. While BLI monitoring in vivo revealed an exponential growth of PC-3 Luc after 2 weeks, a decrease of bone density and bone mineral content was evidenced by microCT as early as 7 days post-injection, reaching significant values at day 21 (30% and 25% loss, respectively), compared with mock-injected controls. Enhanced osteoclast TRAP activity was observed during the first two weeks, highlighting an active interaction between low proliferative PC-3 cells and osteoclasts at the early stage of tumor establishment in bone. Tumor growth detected by BLI was tightly correlated to the osteolysis assessed by microCT (p<0.05). Our results show that the combination of microCT and BLI applied to this tumor osteolysis murine model allows early measurement of intraosseous tumor growth and bone destruction, as well as correlation between both processes kinetics. This model will help to assess new therapeutic approaches targeting intraosseous tumor growth or tumor/osteoclast crosstalk.

Abstract
BACKGROUND In the context of preclinical development, we studied the potential of intra-articular gene delivery using a recombinant adeno-associated virus 5 (rAAV5) encoding a chimeric human tumour necrosis factoralpha (TNFalpha) soluble receptor I linked to a mouse immunoglobulin heavy chain Fc portion (TNF receptor I; TNFRI-Ig). METHODS Expression was under control of a nuclear factor kappa B (NFkappaB)-responsive promoter and compared with a cytomegalovirus (CMV) promoter (rAAV5.NFkappaB-TNFRI-Ig and rAAV5.CMV-TNFRI-Ig, respectively). RESULTS Fibroblast-like synoviocytes transduced in vitro with rAAV5.NFkappaB-TNFRI-Ig were able to produce TNFRI-Ig protein in response to several stimuli, and this was inhibited upon treatment with a specific NFkappaB blocking agent. A bioassay revealed that the synthesised TNFRI-Ig was bioactive, showing a higher affinity for human than for rat TNFalpha. Transcription of the transgene and protein production were detectable in joints injected with both constructs. No dissemination of the vector was observed outside the joints. A significant reduction in paw swelling was seen in rats treated with rAAV5.NFkappaB-TNFRI-Ig. This clinical effect was accompanied by a decrease in pro-inflammatory cytokine levels and an increase in IL10 expression in the synovium. CONCLUSION These results provide evidence that intra-articular gene therapy using rAAV5 encoding TNFRI-Ig may be a safe and feasible approach for the treatment of rheumatoid arthritis. The higher affinity for human TNFalpha suggests that in patients with rheumatoid arthritis the therapeutic effect might be even more pronounced than in rat adjuvant arthritis.

Abstract
BACKGROUND Mesenchymal stem cells (MSC) are widely investigated for cell therapy purposes as support of hematopoietic cell transplantation, skeletal tissue regeneration, or as a cell delivery system of therapeutic agents in cancer. However, because of their immunosuppressive capacities, we investigated the effect of MSC on the development of syngeneic tumors. METHODS The murine MSC line C3H10T1/2 was coinjected with the Renca adenocarcinoma or the B16 melanoma cell lines in BALB/c mice. RESULTS The injection of MSC permitted the growth of the allogeneic B16 tumor cells and reduced the delay of tumor appearance when Renca cells were implanted, without modifying the kinetics of tumor growth. This effect was observed even with a low ratio of cancer cells, mimicking minimal residual disease. In this last case, no MSC were detected in the tumor mass, suggesting that cell contact was not necessary. The presence of MSC did not enhance the development of lung metastasis after systemic injection of Renca cells. Because the proliferative rate of Renca cells was not affected by in vitro coculture with MSC, this observation is likely due to a systemic suppressive effect on the host immune system. CONCLUSIONS Altogether, these data suggest that MSC did not interfere with the kinetics of tumor development but may reduce the delay for tumor occurrence. An important finding of this study is that a low but relevant amount of MSC may induce tumor rejection.

Abstract
Dendritic cells (DCs) are specialized APCs with an important role in the initiation and regulation of immune responses. Immature DCs (iDCs) reportedly mediate tolerance in the absence of maturation/inflammatory stimuli, presumably by the induction of regulatory T cells. In this study, we show for the first time that repetitive iDC injections trigger the expansion of a novel regulatory population with high immunomodulatory properties, able to protect mice from collagen-induced arthritis. These regulatory T cells are characterized by the expression of the CD49b molecule and correspond to a CD4+ alpha-galactosylceramide/CD1d-nonrestricted T cell population producing IL-10. Adoptive transfer of < 10(5) TCRbeta+ CD49b+ cells isolated from the liver of iDCs-vaccinated mice, conferred a complete protection against arthritis. This protection was associated with an attenuation of the B and T cell response associated with a local secretion of IL-10. Thus, together these data demonstrate that iDCs can expand and activate a novel regulatory population of CD49b+ T cells, with high immunosuppressive potential able to mediate protection against a systemic autoimmune disease.

Abstract
OBJECTIVE Tumor necrosis factor alpha (TNFalpha) is among the most prominent cytokines in rheumatoid arthritis (RA) and is secreted mainly by macrophages. A direct method for restoring the immunologic balance in RA is use of small interfering RNA (siRNA) for silencing the TNFalpha transcript. The aim of this study was to determine the therapeutic effect of systemic administration of TNFalpha siRNA in an experimental model of RA, optimizing its delivery using new liposome formulations. METHODS Murine macrophages were transfected with siRNA targeting TNFalpha, and expression was measured. The therapeutic effect in collagen-induced arthritis (CIA) was assessed after intravenous delivery of TNFalpha siRNA. Delivery was optimized using a carrier DNA for complexation with the cationic liposome RPR209120/DOPE. Levels of TNFalpha and other cytokines were measured in sera and joint tissue-conditioned media. Biodistribution was determined using a fluorescent siRNA. RESULTS In vitro, TNFalpha siRNA efficiently and specifically modulated the expression of TNFalpha at both the messenger RNA and protein levels. In vivo, complete cure of CIA was observed when TNFalpha siRNA was administered weekly, complexed with the liposome and combined with carrier DNA. Inhibition (50-70%) of articular and systemic TNFalpha secretion was detected in the siRNA-injected groups, which correlated with a decrease in the levels of interleukin-6 and monocyte chemotactic protein 1. The main organs targeted by siRNA were the liver and spleen; the addition of liposome RPR209120 and carrier DNA significantly increased organ uptake. CONCLUSION We demonstrated the efficiency of systemic delivery of siRNA designed to silence TNFalpha in CIA, using a liposome carrier system as a way to address the methodologic limitations in vivo.

BACKGROUND Electric pulse mediated gene transfer has been applied successfully in vivo for increasing naked DNA administration in various tissues. To achieve non-viral gene transfer into arthritic joint tissue, we investigated the use of electrotransfer (ET). Because anti-inflammatory cytokine strategies have proven efficient in experimental models of arthritis, we compared the therapeutic efficiency of local versus systemic delivery of the interleukin-10 (IL-10) using in vivo ET. METHODS A plasmid vector expressing IL-10 was transferred into DBA/1 mouse knee joints by ET with 12 pulses of variable duration and voltage. The kinetics of transgene expression were analyzed by specific enzyme-linked immunosorbent assay (ELISA) in sera and knees. Optimal conditions were then used to deliver increasing amounts of IL-10 plasmid intra-articularly (i.a.) in the collagen-induced arthritis (CIA) mouse model. The therapeutic efficiency was compared with the potency of intra-muscular (i.m.) ET. RESULTS Following i.a. ET, local IL-10 secretion peaked on day 7 and dropped 2 weeks after. A second ET produced the same kinetics without enhancing gene transfer efficiency, while transgene was still detected in injected muscles 4 weeks after ET. Only the i.m. ET of 25 microg of IL-10 significantly inhibited all the clinical and biological features of arthritis. The i.a. ET only showed mild improvement of arthritis when 100 microg of IL-10 plasmid were electrotransfered weekly from day 18 following arthritis induction. CONCLUSIONS The present results suggest that gene transfer into arthritic joints by ET is an effective means to deliver anti-inflammatory cytokines. However, short duration of transgene expression impedes a significant effect for the treatment of arthritis, making i.m. ET more potent than i.a. ET for clinical benefit in CIA.

Abstract
Members of the adeno-associated virus (AAV) family are good candidates for the treatment of ocular diseases because of their relative lack of pathogenicity. We studied the effect of intraocular injection of AAV2-viral IL-10 (vIL-10) on retinal S-antigen-induced experimental autoimmune uveoretinitis (EAU) in Lewis rats. We demonstrated that AAV2/2-GFP injected into the vitreous body transduced the iris and ciliary body, or anterior uvea, and the retina. We showed that intravitreal injection of the AAV2/2-tetON-vIL-10 construct achieved detectable levels of vIL-10 mRNA and protein within the eye and was effective in protecting the rat retina against destruction. This protection was dependent on the level of vIL-10 present in the aqueous humor/ vitreous body. Intravitreal injection of the same construct encased within an AAV5 shell, AAV2/5-tetONvIL- 10, did not confer any degree of protection. It appeared that the AAV2/5 vectors did not transduce the anterior uvea, the site at which inflammatory cells first localize in EAU, nor the ganglion cell layer; induced low expression of vIL-10 mRNA; and did not achieve detectable levels of transgene expression in the aqueous humor/vitreous body. Local treatment with AAV2/2-tetON-vIL-10 did not dampen the systemic immune response, as determined by S-antigen-specific lymphocyte proliferation. Our results show that local intravitreal injection of AAV2/2 is an effective means by which to deliver immunoregulatory molecules into the eye during uveitis, a chronic human ocular disease.

Transcriptional profiles discriminate bone marrow-derived and synovium-derived mesenchymal stem cells. Arthritis Res Ther 2005; 7:R1304-15.

Abstract
Previous studies have reported that mesenchymal stem cells (MSC) may be isolated from the synovial membrane by the same protocol as that used for synovial fibroblast cultivation, suggesting that MSC correspond to a subset of the adherent cell population, as MSC from the stromal compartment of the bone marrow (BM). The aims of the present study were, first, to better characterize the MSC derived from the synovial membrane and, second, to compare systematically, in parallel, the MSC-containing cell populations isolated from BM and those derived from the synovium, using quantitative assays. Fluorescent-activated cell sorting analysis revealed that both populations were negative for CD14, CD34 and CD45 expression and that both displayed equal levels of CD44, CD73, CD90 and CD105, a phenotype currently known to be characteristic of BM-MSC. Comparable with BM-MSC, such MSC-like cells isolated from the synovial membrane were shown for the first time to suppress the T-cell response in a mixed lymphocyte reaction, and to express the enzyme indoleamine 2,3-dioxygenase activity to the same extent as BM-MSC, which is a possible mediator of this suppressive activity. Using quantitative RT-PCR these data show that MSC-like cells from the synovium and BM may be induced to chondrogenic differentiation and, to a lesser extent, to osteogenic differentiation, but the osteogenic capacities of the synovium-derived MSC were significantly reduced based on the expression of the markers tested (collagen type II and aggrecan or alkaline phosphatase and osteocalcin, respectively). Transcription profiles, determined with the Atlas Human Cytokine/Receptor Array, revealed discrimination between the MSC-like cells from the synovial membrane and the BM-MSC by 46 of 268 genes. In particular, activin A was shown to be one major upregulated factor, highly secreted by BM-MSC. Whether this reflects a different cellular phenotype, a different amount of MSC in the synovium-derived population compared with BM-MSC adherent cell populations or the impact of a different microenvironment remains to be determined. In conclusion, although the BM-derived and synovium-derived MSC shared similar phenotypic and functional properties, both their differentiation capacities and transcriptional profiles permit one to discriminate the cell populations according to their tissue origin.
