Abstract
The severity of osteoarthritis (OA) and cartilage degeneration is highly associated with synovial inflammation. Although recent investigations have revealed a dysregulated crosstalk between fibroblast-like synoviocytes (FLSs) and macrophages in the pathogenesis of synovitis, limited knowledge is available regarding the involvement of exosomes. Here, increased exosome secretion is observed in FLSs from OA patients. Notably, internalization of inflammatory FLS-derived exosomes (inf-exo) can enhance the M1 polarization of macrophages, which further induces an OA-like phenotype in co-cultured chondrocytes. Intra-articular injection of inf-exo induces synovitis and exacerbates OA progression in murine models. In addition, it is demonstrated that inf-exo stimulation triggers the activation of glycolysis. Inhibition of glycolysis using 2-DG successfully attenuates excessive M1 polarization triggered by inf-exo. Mechanistically, HIF1A is identified as the determinant transcription factor, inhibition of which, both pharmacologically or genetically, relieves macrophage inflammation triggered by inf-exo-induced hyperglycolysis. Furthermore, in vivo administration of an HIF1A inhibitor alleviates experimental OA. The results provide novel insights into the involvement of FLS-derived exosomes in OA pathogenesis, suggesting that inf-exo-induced macrophage dysfunction represents an attractive target for OA therapy.

Abstract
Long noncoding RNAs (lncRNAs) are a regulatory class of noncoding RNAs with a wide range of activities such as transcriptional and post-transcriptional regulations. Emerging evidence has demonstrated that various lncRNAs contribute to the initiation and progression of Rheumatoid Arthritis (RA) through distinctive mechanisms. The present study reviews the recent findings on lncRNA role in RA development. It focuses on the involvement of different lncRNAs in the main steps of RA pathogenesis including T cell activation, cytokine dysregulation, fibroblast-like synoviocyte (FLS) activation and joint destruction. Besides, it discusses the current findings on RA diagnosis and the potential of lncRNAs as diagnostic, prognostic and predictive biomarkers in Rheumatology clinic.

Abstract
The morphology of fibroblast-like synoviocytes (FLS) issued from the synovial fluid (SF) of patients suffering from osteoarthritis (OA), rheumatoid arthritis (RA), or from healthy subjects (H), as well as the ultrastructure and mechanical properties of the FLS-secreted extracellular vesicles (EV), were analyzed by confocal microscopy, transmission electron microscopy, atomic force microscopy, and tribological tests. EV released under healthy conditions were constituted of several lipid bilayers surrounding a viscous inner core. This "gel-in" vesicular structure ensured high mechanical resistance of single vesicles and good tribological properties of the lubricant. RA, and to a lesser extent OA, synovial vesicles had altered morphology, corresponding to a "gel-out" situation with vesicles surrounded by a viscous gel, poor mechanical resistance, and poor lubricating qualities. When subjected to inflammatory conditions, healthy cells developed phenotypes similar to that of RA samples, which reinforces the importance of inflammatory processes in the loss of lubricating properties of SF.

Abstract
OBJECTIVE The aim of the study was to investigate the role and regulatory mechanisms of fibroblast-like synoviocytes (FLSs) and their senescence in the progression of osteoarthritis (OA). METHODS Synovial tissues from normal patients and patients with OA were collected. Synovium FLS senescence was analysed by immunofluorescence and western blotting. The role of methyltransferase-like 3 (METTL3) in autophagy regulation was explored using N6-methyladenosine (m6A)-methylated RNA and RNA immunoprecipitation assays. Mice subjected to destabilisation of the medial meniscus (DMM) surgery were intra-articularly injected with or without pAAV9 loaded with small interfering RNA (siRNA) targeting METTL3. Histological analysis was performed to determine cartilage damage. RESULTS Senescent FLSs were markedly increased with the progression of OA in patients and mouse models. We determined that impaired autophagy occurred in OA-FLS, resulting in the upregulation of senescence-associated secretory phenotype (SASP). Re-establishment of autophagy reversed the senescent phenotype by suppressing GATA4. Further, we observed for the first time that excessive m6A modification negatively regulated autophagy in OA-FLS. Mechanistically, METTL3-mediated m6A modification decreased the expression of autophagy-related 7, an E-1 enzyme crucial for the formation of autophagosomes, by attenuating its RNA stability. Silencing METTL3 enhanced autophagic flux and inhibited SASP expression in OA-FLS. Intra-articular injection of synovium-targeted METTL3 siRNA suppressed cellular senescence propagation in joints and ameliorated DMM-induced cartilage destruction. CONCLUSIONS Our study revealed the important role of FLS senescence in OA progression. Targeted METTL3 inhibition could alleviate the senescence of FLS and limit OA development in experimental animal models, providing a potential strategy for OA therapy.

Abstract
Our study aimed to determine the effects of sodium tanshinone IIA sulfonate (STS) on proliferation, migration, invasion, and inflammation in rheumatoid arthritis human fibroblast-like synoviocytes (RA-HFLSs). Firstly, results demonstrated STS reduced proliferation, migration, invasion in HFLSs. Also, we found that STS could alleviate the reorganizations of F-actin cytoskeleton in TNF-α-treated HFLSs. In addition, STS decreased the production of IL-1β, IL-6, MMP-1, and MMP-3 in TNF-α-treated RA-HFLSs. Further study showed that STS blocked MAPK/NF-κB activations in TNF-α-stimulated RA-HFLSs. Moreover, we illustrated that STS could alleviate rheumatoid arthritis progression and prevent inflammation damage in joint tissues of collagen-induced arthritis (CIA) mice. Taken together, this study suggested that STS inhibited proliferation, migration, invasion, and inflammation of RA-HFLSs by blocking MAPK/NF-κB pathways.

Abstract
Epidermal growth factor receptor (EGFR) signaling has been reported to play a vital role in the pathogenesis of rheumatoid arthritis (RA). In current study, we sought to observe whether the active immunization induced by the mimotope could recognize EGFR, inhibit their signaling and disrupt the pathogenic behavior of fibroblast-like synoviocytes (FLS) from RA patients. We prepared a linked EGFR mimotope and performed series of experiments to detect whether the mimotope could induce the desired immune responses. To our surprises, we detected the expression of EGFR variant III (EGFRvIII), but not EGFR in the synovial tissues and FLS from patients with aggressive RA by the linked EGFR mimotope-induced antibodies (LEMIA). Meanwhile, LEMIA could inhibit the signaling caused by the autophosphorylation of EGFRvIII in the FLS. The proliferation, migration, invasion and anti-apoptosis capabilities of the EGFRvIII-expressed FLS were disrupted by LEMIA. These results suggest that EGFRvIII signaling may participate in the malignant behaviors of FLS from aggressive RA. Meanwhile, the linked EGFR mimotope could be used to detect the expression of EGFRvIII and developed to be a potential therapy agent against the aggressive FLS.

Abstract
Rheumatoid arthritis (RA) is a systemic autoimmune disease characterized by destructive hyperplasia of the synovium. Fibroblast-like synoviocytes (FLS) are a major component of synovial pannus and actively participate in the pathologic progression of RA. How rheumatoid FLS acquire and sustain such a uniquely aggressive phenotype remains poorly understood. We describe the current state of knowledge of the molecular alterations in rheumatoid FLS at the genomic, epigenomic, transcriptomic, proteomic, and metabolomic levels, which offers a means to reconstruct the pathways leading to rheumatoid pannus. Such data provide new pathologic insight and suggest means to more sensitively assess disease activity and response to therapy, as well as support new avenues for therapeutic development.

Abstract
OBJECTIVES It is not clear whether TREM-2 (the "triggering receptor expressed on myeloid cells 2") is expressed in fibroblast-like synovial cells (FLSs). In this study, we aimed to determine the expression of TREM-2 in rheumatoid arthritis (RA)-FLSs and explore whether and how TREM-2 modulates the function of RA-FLSs. METHODS Western blot and RT-PCR were used to detect the expression of TREM-2 in RA-FLSs, siRNA and lentivirus were used to down-regulate and up-regulate the expression of TREM-2 in RA-FLSs. Then mRNA expression of IL-1β, IL-6, and MMP-13 was determined by RT-qPCR. Protein secretion of IL-1β, IL-6, and MMP-13 in the supernatant was determined by ELISA assay; expression of cell signal transduction molecules was determined by western blot. RESULTS A: Relative to OA-FLSs, mRNA and protein expression levels of TREM-2 in RA-FLSs are significantly elevated. TREM-2 protein is mainly expressed in the cytoplasm of RA-FLSs; B: In RA, the expression of TREM-2 was reduced at first and then up-regulated after stimulation by TNF-α. TREM-2 also inhibited the activation of TNF-α induced of inflammation in RA-FLSs by the p38 pathway, which regulates the production of cytokines and matrix metalloproteinases. CONCLUSIONS TREM-2 expressed in RA-FLSs and TNF-α mediated reduction of inflammatory reactions. These phenomena indicated that TREM-2 may be a potential target in the treatment of RA.

Abstract
OBJECTIVES Recent studies have indicated that piperlongumine (PLM) may exert anti-inflammatory effects. In the present study, we determined the effect of PLM on the proliferation, apoptosis, migration and invasion of fibroblast-like synoviocytes (FLS) from patients with rheumatoid arthritis (RA) (referred to herein as RA FLS). We further explored the mechanisms by which the studied compound inhibits the functions of RA FLS. METHODS RA FLS viability and apoptosis were tested using MTT and Annexin V/PI assays, respectively. We performed an EDU assay to examine the proliferation of RA FLS. The migration and invasion of these cells were measured using a transwell chamber method and wound closure assay. The MMP-1, MMP-3, and MMP-13 levels in the culture supernatants of RA FLS were detected using a Luminex Assay kit. The intracellular ROS levels were detected using DCFH-DA. The expression levels of signal transduction proteins were measured using western blot. RESULTS We found that PLM induced apoptosis in RA FLS at concentrations of 15 and 20 μM. The proliferation of RA FLS was downregulated by PLM at concentrations of 1, 5 and 10 μM. Migration and invasion of RA FLS were reduced by PLM at concentrations of 1, 5 and 10 μM. PLM also inhibited cytoskeletal reorganization in migrating RA FLS and decreased TNF-α-induced intracellular ROS production. Moreover, we demonstrated the inhibitory effect of PLM on activation of the p38, JNK, NF-κB and STAT3 pathways. CONCLUSIONS Our findings suggest that PLM can inhibit proliferation, migration and invasion of RA FLS. Moreover, these data suggests that PLM might have therapeutic potential for the treatment of RA.

Abstract
OBJECTIVES We studied the anti-angiogenic effect of interleukin-35 (IL-35) by investigating its effects on signal transmission through the Janus kinase signal transducer and activator of transcription (JAK-STAT) pathway in fibroblast-like synoviocytes (FLS). METHODS Using the collagen-induced arthritis (CIA) model of rheumatoid arthritis (RA), we derived and cultured FLS, stimulated FLS with IL-35 at different concentrations and examined the expression levels of mRNA and protein of both vascular endothelial growth factor (VEGF), fibroblast growth factor-2 (FGF-2), endostatin, TNF-α, and IL-6 using reverse transcription polymerase chain reaction (RT-PCR) and immunoblotting. We used Western blotting to study the effects of IL-35 on the function of the JAK-STAT pathway in FLS. RESULTS IL-35 treatment inhibited the expression of VEGF, FGF-2, TNF-α and IL-6, and increased the expression of endostatin in FLS. Western blotting showed that IL-35 treatment of CIA-derived FLS resulted in signalling through STAT1, but not through STAT3 or STAT5. CONCLUSIONS IL-35 signalling through STAT1 and inhibition of the expression of mediators of angiogenesis and inflammation in FLS provide a likely mechanism for anti-angiogenic effects seen in experimental models of RA. Our data suggest that IL-35 and its signalling pathway represent a therapeutic target for the treatment of RA and other angiogenesis-related diseases.

Abstract
High-resolution atomic force microscopy (AFM) was used for the in situ evaluation of the anti-inflammatory effects of triptolide on rheumatoid arthritis (RA) fibroblast-like synoviocytes (FLS) to understand the anti-RA effects of triptolide, based on the morphological and biophysical changes observed in RA-FLS. RA-FLS have been reported to play a primary role in inflammatory bone destruction during the development of RA and thus are regarded as an important target for RA treatment. Triptolide pretreatment significantly inhibited tumor necrosis factor-α-induced expression of the interleukin (IL)-1β, IL-6, and IL-8 genes in MH7A cells. Using AFM, we showed that triptolide-induced morphological damage in MH7A cells by inducing significant ultrastructure changes in the membrane, which were closely related to triptolide-induced apoptosis in MH7A cells. Using force measurements determined with AFM, triptolide was shown to increase the stiffness of MH7A cells. These findings not only revealed the strong anti-inflammatory effects of triptolide on RA-FLS, highlighting triptolide as a potential anti-RA agent, but also revealed the possible use of AFM for studying anti-inflammatory responses in RA-FLS, which we expect to be developed into a potential tool for anti-RA drug studies in RA-FLS.

Abstract
Fibroblast-like synoviocytes (FLS) reside in the synovial membrane of diarthrodial joints and are exposed to a dynamic fluid environment that presents both physical and chemical stimuli. The ability of FLS to sense and respond to these stimuli plays a key role in their normal function, and is implicated in the alterations to function that occur in osteoarthritis (OA). The present work characterizes the response of FLS to fluid flow-induced shear stress via real-time calcium imaging, and tests the hypothesis that this response is modulated by interleukin-1α (IL-1α), a cytokine elevated in OA. FLS demonstrated a robust calcium signaling response to fluid shear that was dose dependent upon stress level and required both external and internal calcium sources. Preconditioning with 10ng/mL IL-1α for 24h heightened this shear stress response by significantly increasing the percent of responding cells and peak magnitude, while significantly decreasing the time for a peak to occur. Intercellular communication via gap junctions was found to account for a portion of the FLS population response in normal conditions, and was significantly increased by IL-1α preconditioning. IL-1α was also found to significantly increase average length and incidence of the primary cilium, an organelle commonly implicated in shear mechanosensing. These findings suggest that the elevated levels of IL-1α found in the OA environment heighten FLS sensitivity to fluid shear by altering both intercellular communication and individual cell sensitivity, which could affect downstream functions and contribute to progression of the disease state.

Abstract
Blocked apoptosis and aggressive inflammatory responses occur in fibroblast-like synoviocyte (FLS) of rheumatoid arthritis (RA) patients. Although Brahma-related gene 1 (BRG1) is considered as a tumor suppressor, few research covers its role in RA. This study aims to reveal effects and potential mechanisms of BRG1 in human FLS cell line MH7A.BRG1 expression in MH7A cells was altered by transfection of overexpression vectors or short hairpin RNAs (shRNAs). Cell viability and apoptosis were detected by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and flow cytometry after transfection. Factors involved in inflammation and apoptosis were quantified by qPCR and Western blot. The interaction between BRG1 and p53 was assessed by immunoprecipitation (IP).Results showed that BRG1 overexpression significantly suppressed MH7A cell viability and induced apoptosis (P < 0.01), and its knockdown had opposite effects. BRG1 reduced mRNA levels of matrix metallopeptidase 3, TIMP metallopeptidase inhibitor 2, cyclooxygenase 2, and interleukin 6, implying its suppressive effects on inflammation. BRG1 interacted with and promoted p53 (P < 0.05). B-cell chronic lymphocytic leukemia/lymphoma 2 was suppressed (P < 0.05), while cytochrome c, caspase 3 (CASP3) and CASP9 were activated (P < 0.01) by BRG1. However, the regulation on these factors was abrogated by p53 knockdown (P < 0.01).These findings suggest that BRG1 may induce apoptosis and suppress inflammation in MH7A cells. Potential functional mechanisms involve the regulation of apoptotic factors by BRG1, which may depend on the recruitment and promotion of p53. This study provides the essential proof for applying BRG1 to the molecular therapy of RA.
