Ermann J, Fathman CG. 1. Trabandt A, Gay RE, Fassbender HG, Gay S. Cathepsin B in synovial cells at the site of joint destruction in rheumatoid arthritis. Pivotal downstream signalling cascades including the MAP kinase system and the transcription factor NFκB are activated in the synovial fibroblast through pro-inflammatory cytokines such as TNFα, and various interleukins. Ikeuchi H, Kuroiwa T, Hiramatsu N, et al. Synovial fibroblasts of patients with rheumatoid arthritis attach to and invade normal human cartilage when engrafted into SCID mice. Schedel J, Gay RE, Kuenzler P, et al. However, as with every animal model, the extrapolation of these data to human RA patients is difficult, thus limiting direct conclusions. For example, stable expression of constitutively active Ras resulted in increased levels of cathepsin L [62]. In the context of RA, integrins of the β1 subfamily play an important role. Stimulation by exogenous platelet-derived growth factor and inhibition by transforming growth factor-beta and retinoids. These changes appear to reflect a stable activation of RASFs, which occurs independently of continuous exogenous stimulation. Published by Oxford University Press on behalf of the British Society for Rheumatology. Rather, it has been understood that resident, fibroblast-like cells contribute significantly to the perpetuation of disease, and that they may even play a role in its initiation. Beyond T-Cells: Functional Characterization of CTLA-4 Expression in Immune and Non-Immune Cell Types. Barchowsky A, Frleta D, Vincenti MP. The latter is a component of the hyaline cartilage that is mainly produced by chondrocytes and synovial fibroblasts. 2020 Oct 14;11:585282. doi: 10.3389/fimmu.2020.585282. Vasudevan KM, Gurumurthy S, Rangnekar VM. Such cytokines, together with growth factors, thus play an important role both in the continuous stimulation of RASFs towards aggressive behaviour as well as in the crosstalk between RASFs and other cell types in the synovium. NFκB, composed of DNA-binding heterodimers, is normally retained in the cytoplasm by its natural counterpart, IκB. Metrics details.

Prominent examples include well-characterized cytokines like tumour necrosis factor alpha (TNFα) and interleukin (IL)-1, and also more recently described mediators like IL-15, IL-21R [20] and IL-22 [21]. Rheumatoid arthritis (RA) is a chronic inflammatory disease with progressive joint destruction. Author information: (1)Department of Rheumatology and Immunology, Changhai Hospital, Second Military Medical University, 168 Changhai Road, Shanghai 200433, China. In spite of significant improvements in the treatment of RA, there is still a need for the identification of new pathways involved in the modulation of inflammation in order to further increase efficacy, particularly in patients in whom the disease does not respond to current therapies.

Gene therapy in autoimmune disease. Schedel J, Seemayer CA, Pap T, et al. Miura and Kanazawa Inflammation and Regeneration (2020) 40:7 Page 8 of 9. On the other hand, transcription factors, modulated proto-oncogenes and tumour suppressors are also of potential therapeutic interest in the case of RASFs. Transgenic mice expressing human tumour necrosis factor: a predictive genetic model of arthritis. Synovial hyperplasia, frequently found in patients with progressive RA, is positive for S100A4 and vimentin, markers of mesenchymal stromal cells (MSCs), and podoplanin, a marker of SFs in the hyperplastic synovial lining layer. Modified expression of c-Fos and c-Jun proteins and production of interleukin-1 beta in patients with rheumatoid arthritis. These rheumatoid arthritis synovial fibroblasts (RASFs) constitute a quite unique cell type that distinguishes RA from other inflammatory conditions of the joints. Perlman H, Liu H, Georganas C, et al. Silman AJ. While the aetiopathogenesis is only partially understood, the involvement of immune cells and their respective pro-inflammatory mediators is a common hallmark of RA as of all systemic autoimmune disorders [4, 6–8]. Trabandt A, Aicher WK, Gay RE, et al. Such events might explain the activation of the rheumatoid synovium. Rheumatoid arthritis (RA) is a chronic autoimmune-disease of unknown origin that primarily affects the joints and ultimately leads to their destruction. Urokinase-type plasminogen activator potentiates lipopolysaccharide-induced neutrophil activation. Direct mechanisms consist of the attachment of fibroblasts to the underlying cartilage by up-regulation of cellular adhesion molecules (CAM) and the destruction of articular cartilage by production of matrix-degrading enzymes [10], while indirect mechanisms govern the differentiation of macrophages into osteoclasts, for example through up-regulation of receptor activator of nuclear factor kappa B ligand (RANKL) [12–14].

The Pathogenesis of Rheumatoid Arthritis – Gene Transfer to Detect Novel Targets for Treatment. This process results in the nuclear translocation of NFκB, enabling it to bind to the promoters of target genes such as IL-6, IL-8 and cyclooxygenase-2. Adhesion molecules are responsible for the anchoring of fibroblasts to the extracellular matrix of the articular cartilage, namely collagen type II and various glycosaminoglycans. Expression of interleukin-21 receptor, but not interleukin-21, in synovial fibroblasts and synovial macrophages of patients with rheumatoid arthritis. In the same context, jun D inhibited the formation of AP-1 thus directly down-regulating the expression of matrix-degrading enzymes. In industrialized countries, alterations in lifestyle and hygiene during the last century have shifted the sp… Qu Z, Garcia CH, O'Rourke LM, Planck SR, Kohli M, Rosenbaum JT. However, a substantial number of patients receiving TNF blockers lack a clinical response, indicating that other, TNF-independent, pathways of inflammation and joint destruction exist in RA. In rheumatoid arthritis the synovial tissue undergoes marked hyperplasia, becomes inflamed and invasive, and destroys the joint1,2. Finally, three principal approaches can be suggested for the future when thinking about fibroblasts as potential targets in order to abolish their potential for joint destruction: (i) interfering with the stimulation by inflammatory cytokines; (ii) modulating molecules that regulate apoptosis or proliferation; and (iii) direct inhibition of distinct matrix-degrading enzymes such as matrix metalloproteinases and cathepsins. The AP-1 site and MMP gene regulation: what is all the fuss about? Cartilage degradation and invasion by rheumatoid synovial fibroblasts is inhibited by gene transfer of TIMP-1 and TIMP-3.

In this context, RA represents one of the most common autoimmune-related diseases, affecting as much as 1% of Western populations. The synovium is a mesenchymal tissue composed mainly of fibroblasts, with a lining and sublining that surround the joints. Tissue degradation comprises the following major pathophysiological phenomena: growth, spreading and invasion of inflamed synovial tissue, and destruction of cartilage and bone. In this context, the tumour suppressor p53 and its downstream molecule p21 have also been investigated. Plater-Zyberk C, Joosten LA, Helsen MM, et al. Anchorage-independent growth of synoviocytes from arthritic and normal joints. The RA synovial tissue is typically characterized by synovial hyperplasia, also called pannus, which is infiltrated with inflammatory cells. L. C. Huber, O. Distler, I. Tarner, R. E. Gay, S. Gay, T. Pap, Synovial fibroblasts: key players in rheumatoid arthritis, Rheumatology, Volume 45, Issue 6, June 2006, Pages 669–675, https://doi.org/10.1093/rheumatology/kel065. Keffer J, Probert L, Cazlaris H, et al. The disease may also affect other parts of the body. Additionally synovial fibroblasts from the lining layer differ in biological and morphological characteristics to those of the sublining layer. Cathepsin B directly facilitates the degradation of ECM proteins, including fibronectin, collagen types I and IV and laminin [56]. Baslund B, Tvede N, Danneskiold-Samsoe B, Peterson J, Peterson L, Schuurmann J. Genes regulating the cell cycle are another option for novel therapeutic strategies. IL-1 and TNFα) and are thought to regulate processes involved in apoptosis and proliferation. Li WQ, Dehnade F, Zafarullah M. Oncostatin M-induced matrix metalloproteinase and tissue inhibitor of metalloproteinase-3 genes expression in chondrocytes requires Janus kinase/STAT signaling pathway. AP-1 binding sites have been found in the promoter region of all MMPs [45], and thus AP-1 appears to play a pivotal role in the transcriptional activation of MMPs. Cathepsin L cleaves collagens type I, II, IX, XI and certain proteoglycans. This study was undertaken to evaluate the fibroblast-specific marker Hsp47 as a quantitative marker for SFs and to analyze its clinicopathologic correlates and evolution after anti-tumor necrosis factor α (anti-TNFα) therapy. Rheumatoid arthritis–a molecular understanding. 6087 Accesses. Bush KA, Farmer KM, Walker JS, Kirkham BW. To explore distinct signaling pathways in this activation we used retroviral gene transfer in the SCID … Expression of cannabinoid receptor 2 and its inhibitory effects on synovial fibroblasts in rheumatoid arthritis. Takayanagi H, Iizuka H, Juji T, et al. MMPs and uPA have been shown to modulate the proteolytic cascade that mediates ECM degradation [59]. This timely review aims to integrate the most recent findings with existing paradigms of fibroblast-related mechanisms of disease. Synovial fibroblasts (SFs) play an important role in the inflammatory process of the synovium. All these processes have a common underlying mechanism, namely the degradation of extracellular matrix, which is mediated by matrix-metalloproteinases (MMPs) [42], cathepsins [43] and an activated plasmin system [44]. From these data, it can be concluded that RASFs are not only stimulated by pro-inflammatory cytokines but also by a cytokine-independent pathway through the activation of p38δ [74]. Activation of synovial fibroblasts (SF) by upregulation of proto-oncogenes is thought to play a major role in rheumatoid joint destruction. Upstream of NFκB, two IκB kinases (IKK1 and -2) regulate IκB activity [82]. In addition, other proteases, such as thrombin, have been demonstrated with inflammation in RA joints induced by the secretion of IL-8 and the recruitment of leucocytes, which release cathepsin B into the synovial fluid [63]. Cysteine proteinase cathepsin K mRNA is expressed in synovium of patients with rheumatoid arthritis and is detected at sites of synovial bone destruction. RA is an immune-mediated inflammatory disease of unknown aetiology that is characterized by chronic inflammatory infiltration of the synovium, leading to eventual cartilage and bone destruction [1]. Pap T, Franz JK, Hummel KM, Jeisy E, Gay R, Gay S. Activation of synovial fibroblasts in rheumatoid arthritis: lack of Expression of the tumour suppressor PTEN at sites of invasive growth and destruction. ‘The time is out of joint’ (Hamlet; 1,5,188)—seen in the context of RA probably due to biological changes within the synovial fibroblast. Dike LE, Farmer SR. Purpose of review Synovial fibroblasts continue to grow in prominence both as the subjects of research into the pathogenesis of rheumatoid arthritis and as novel therapeutic targets.

The role of p38 mitogen-activated protein kinase in IL-6 and IL-8 production from the TNF-alpha- or IL-1beta-stimulated rheumatoid synovial fibroblasts. The rheumatoid arthritis (RA) synovium is characterised by the presence of an aggressive population of activated synovial fibroblasts (RASFs) that are prominently involved in the destruction of articular cartilage and bone. Various studies have revealed high transcription of immediate early genes in RASFs, for example egr-1 [35, 37] and fos [36, 38], as well as proto-oncogenes such as jun [36, 38] and myc [52]. Rheumatoid arthritis (RA) is a chronic autoimmune-disease of unknown origin that primarily affects the joints and ultimately leads to their destruction. Expression of sentrin, a novel antiapoptotic molecule, at sites of synovial invasion in rheumatoid arthritis. NF-kappaB activation provides the potential link between inflammation and hyperplasia in the arthritic joint. In addition, alterations in the levels of expression and function of the tumour suppressor PTEN (phosphatase and tensin homologue deleted from chromosome 10) have been found in RASFs. Zinkernagel RM.

In the present study, we searched for mutant PTEN transcripts in aggressive rheumatoid arthritis synovial fibroblasts (RA-SF) and studied the expression of PTEN in RA. In this regard, macrophages, T cells and their respective cytokines play a pivotal role in RA. Upstream of these transcription factors, all three stress- and mitogen-activated protein kinases (SAPK/MAPK), namely the extracellular regulated kinase (ERK), c-Jun N-terminal kinase (JNK) and p38 kinase, are highly active in chronic synovitis and also involved in the regulation of MMP expression [49]. However, it has been well established that the altered morphology and the aggressive behaviour of RASFs mirror specific alterations in the transcription of disease-relevant genes and in intracellular signalling pathways, including alterations in apoptotic cascades.
