Proteomics analyses of human plasma reveal triosephosphate isomerase as a potential blood marker of methotrexate resistance in rheumatoid arthritis. Rheumatology (Oxford) 2024; 63:1368-1376. [PMID: 37527020 DOI: 10.1093/rheumatology/kead390] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2023] [Revised: 07/02/2023] [Accepted: 07/09/2023] [Indexed: 08/03/2023] Open
Abstract
OBJECTIVE The objective of this study was to assess differentially expressed blood proteins between patients with active RA and patients in remission after MTX treatment, with the aim of identifying a biomarker of MTX resistance (MTXR). METHODS Two populations of RA patients treated with a stable dose of s.c. MTX for at least 3 months were constituted according to the DAS28: remission (DAS28 < 2.6; n = 24) and active disease (DAS28 > 3.2; n = 32). The two groups of RA patients were homogeneous regarding their epidemiological characteristics, except for the duration of treatment, which was longer in the remission group. After collection of a blood sample, plasma protein digestion was performed, followed by untargeted proteomics analysis. Then, a targeted analysis was performed to confirm the results of the untargeted approach. RESULTS Untargeted proteomics analysis revealed eight plasma proteins that were differentially expressed between the two groups of patients. Among them, triosephosphate isomerase (TPI-1) and glucose-6-phosphate isomerase (GPI), which are main actors in glycolysis, were found down-regulated in the active group. This result was confirmed for TPI-1 in the targeted proteomics analysis. CONCLUSION A first step was achieved in the search for biomarkers of MTXR, with the identification of two actors in glycolysis (TPI-1 and GPI). The next step will be to confirm these results in a larger cohort, including samples from treatment-naive patients, to assess the predictive potential of these protein markers.

Abstract
Murine models have played an indispensable role in the understanding of rheumatic and musculoskeletal disorders (RMD), elucidating the genetic, endocrine and biomechanical pathways involved in joint pathology and associated pain. To date, the available models in RMD can be classified as induced or spontaneous, both incorporating transgenic alternatives that improve specific insights. It is worth noting that the selection of the most appropriate model together with the evaluation of their specific characteristics and technical capabilities are crucial when designing the experiments. Furthermore, it is also imperative to consistently adhere to the ethical standards concerning animal experimentation. Recognizing the inherent limitation that any model can entirely encapsulates the complexity of the pathophysiology of these conditions, the aim of this review is to provide an updated overview on the methodology of current murine models in major arthropathies and their immune-mediated pathways, addressing to basic, translational and pharmacological research in joint damage and pain.

JOURNAL OF ETHNOPHARMACOLOGY 2023; 314:116553.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Traditional Chinese medicine (TCM) has been used in China for a long time and is gradually gaining more and more recognition worldwide. Chaenomeles speciosa (CSP) (Chinese Pinyin: mugua) is a medicinal and food herb that has long been used as a folk medicine for rheumatic diseases, yet its bioactive components and therapeutic mechanisms are not clear. AIM OF THE STUDY Exploring anti-inflammatory and chondroprotective effects of CSP on rheumatoid arthritis (RA) and its possible targets of action. MATERIALS AND METHODS In this study, we performed an integrated approach of network pharmacology, molecular docking and experimental studies to explore the potential mechanism of action of CSP in the treatment of cartilage damage in RA. RESULTS Studies have shown that Quercetin, ent-Epicatechin and Mairin may be the main active compounds of CSP in the treatment of RA, while AKT1, VEGFA, IL-1β, IL-6, MMP9 etc. are considered as core target proteins to which the main active compounds in CSP bind, as further confirmed by molecular docking. In addition, the potential molecular mechanism of CSP for the treatment of cartilage damage in RA predicted by network pharmacology analysis was validated by in vivo experiments. CSP was found to downregulate the expression of AKT1, VEGFA, IL-1β, IL-6, MMP9, ICAM1, VCAM1, MMP3, MMP13 and TNF-α and increase the expression of COL-2 in the joint tissue of Glucose-6-Phosphate Isomerase (G6PI) model mice. Thus CSP contributes to the treatment of rheumatoid arthritis cartilage destruction. CONCLUSION This study showed that CSP has multi-component, multi-target and multi-pathway characteristics in treating cartilage damage in RA, which can achieve the effect of treating RA by inhibiting the expression of inflammatory factors, reducing neovascularization and alleviating the damage to cartilage caused by the diffusion of synovial vascular opacities, and reducing the degradation of cartilage by MMPs to play a protective role in RA cartilage damage. In conclusion, this study indicates that CSP is a candidate Chinese medicine for further research in treating cartilage damage in RA.

Abstract
Glucose 6-phosphate isomerase (G6PI) is an indicator to assist in diagnosis of rheumatoid arthritis (RA) and monitor the disease. It also plays a key role in proliferating RA synovial tissues, pannus formation, and invasion and destruction of articular cartilage. In this study, we synthesized nanoparticles targeting G6PI (siG6PI-MSN) using mesoporous silica nanocarriers (MSN) and small interfering RNA (siRNA), followed by identifying the characteristics and functions, and preliminarily exploring their application in the treatment of RA in vivo with a type II collagen-induced arthritis (CIA) rat model. It showed that the synthetic functionalized carrier had a regular pore structure and a specific volume and surface area. No obvious hemolysis or toxicity of the carrier was found when its concentration was below 100 µg/ml. Cytological results in vitro suggested that siG6PI-MSN significantly inhibited G6PI expression and reduced the ability of proliferation, migration, and invasion of FLSs, compared with the siNC-MSN group. In vivo results in the CIA rat model showed that the arthritis index and degree of joint swelling among rats in the siG6PI-MSN-treatment group were significantly lower than those in the control group. Moreover, the number of FLSs in Synovium and the levels of TNF α and IL-1 β were also significantly decreased in the siG6PI-MSN group. Histopathology of the synovial tissue and cartilage revealed siG6PI-MSN treatment significantly reduced the pathological manifestations of arthritis. In conclusion, siG6PI-MSN effectively suppresses the proliferation and invasive growth of synovial tissue and improve joint swelling and inflammatory infiltration, thereby preventing joint damage in RA. This carrier may be a new therapeutic measure for RA, with potential social and economic benefits.

Abstract
Rheumatoid arthritis (RA) is a chronic systemic autoimmune disease characterized by persistent articular inflammation and joint damage. RA was first described over 200 years ago; however, its etiology and pathophysiology remain insufficiently understood. The current treatment of RA is mainly empirical or based on the current understanding of etiology with limited efficacy and/or substantial side effects. Thus, the development of safer and more potent therapeutics, validated and optimized in experimental models, is urgently required. To improve the transition from bench to bedside, researchers must carefully select the appropriate experimental models as well as draw the right conclusions. Here, we summarize the establishment, pathological features, potential mechanisms, advantages, and limitations of the currently available RA models. The aim of the review is to help researchers better understand available RA models; discuss future trends in RA model development, which can help highlight new translational and human-based avenues in RA research.

Non-invasive monitoring of arthritis treatment response via targeting of tyrosine-phosphorylated annexin A2 in chondrocytes. Arthritis Res Ther 2021; 23:265. [PMID: 34696809 PMCID: PMC8543875 DOI: 10.1186/s13075-021-02643-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2021] [Accepted: 10/04/2021] [Indexed: 11/16/2022] Open
Abstract
BACKGROUND The development and optimization of therapies for rheumatoid arthritis (RA) is currently hindered by a lack of methods for early non-invasive monitoring of treatment response. Annexin A2, an inflammation-associated protein whose presence and phosphorylation levels are upregulated in RA, represents a potential molecular target for tracking RA treatment response. METHODS LS301, a near-infrared dye-peptide conjugate that selectively targets tyrosine 23-phosphorylated annexin A2 (pANXA2), was evaluated for its utility in monitoring disease progression, remission, and early response to drug treatment in mouse models of RA by fluorescence imaging. The intraarticular distribution and localization of LS301 relative to pANXA2 was determined by histological and immunohistochemical methods. RESULTS In mouse models of spontaneous and serum transfer-induced inflammatory arthritis, intravenously administered LS301 showed selective accumulation in regions of joint pathology including paws, ankles, and knees with positive correlation between fluorescent signal and disease severity by clinical scoring. Whole-body near-infrared imaging with LS301 allowed tracking of spontaneous disease remission and the therapeutic response after dexamethasone treatment. Histological analysis showed preferential accumulation of LS301 within the chondrocytes and articular cartilage in arthritic mice, and colocalization was observed between LS301 and pANXA2 in the joint tissue. CONCLUSIONS We demonstrate that fluorescence imaging with LS301 can be used to monitor the progression, remission, and early response to drug treatment in mouse models of RA. Given the ease of detecting LS301 with portable optical imaging devices, the agent may become a useful early treatment response reporter for arthritis diagnosis and drug evaluation.

Abstract
The use of animal models of arthritis is a key component in the evaluation of therapeutic strategies against the human disease rheumatoid arthritis (RA). Here we present quantitative measurements of bone degradation characterised by the cortical bone profile using glucose-6-phosphate isomerase (G6PI) induced arthritis. We applied micro-computed tomography (μCT) during three arthritis experiments and one control experiment to image the metatarsals of the hind paws and to investigate the effect of experimental arthritis on their cortical bone profile. For measurements of the cortical profile we automatically identified slices that are orthogonal to individual metatarsals, thereby making the measurements independent of animal placement in the scanner. We measured the average cortical thickness index (CTI) of the metatarsals, as well as the thickness changes along the metatarsal. In this study we introduced the cortical thickness gradient (CTG) as a new measure and we investigated how arthritis affects this measure. We found that in general both CTI and CTG are able to quantify arthritic progression, whilst CTG was found to be the more sensitive measure.

Abstract
Aim of the study Recent studies demonstrated the association of tumor necrosis factor α-induced protein 3 (TNFAIP3) (rs2230926) and tumor necrosis factor receptor associated factor 1 (TRAF1) (rs10818488) with rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE) in different populations. We aimed at determining whether they confer susceptibility to SLE and RA in Egyptian population and if there is any relation to disease activity and auto-antibodies profile. Material and methods A case-control study involving 105 individuals with RA, 90 with SLE and 75 healthy controls was performed using TaqMan genotyping assay for two SNPs that showed the best evidence of association in the previous Caucasian studies. Results We detected significant differences in G allele frequency of TNFAIP3 (rs2230926) with SLE (p = 0.017*) and RA (OR = 2.333; 95% CI: 1.103-4.935, p = 0.023*) and association with RA disease activity (< 0.001). The A allele of TRAF1 was significantly increased in RA compared to controls(p = 0.049) and with RA activity (p = 0.001), while TRAF1 polymorphism did not exhibit any significant difference in the frequencies of genotypes or alleles in SLE and control (p = 0.280). Conclusions TNFAIP3 is a susceptibility gene to SLE and RA in the Egyptian population and is correlated to disease activity and the presence of autoantibodies while TRAF1 polymorphisms increase the risk of RA but not to SLE in Egyptian populations.

Abstract
Interruption of cytokine signaling, by targeting either the cytokine itself or its cellular receptor, is a mainstay in the therapy for patients with rheumatic diseases. Interleukin (IL)-33, a member of the IL-1 cytokine family, has emerged as an important mediator of inflammatory responses. In a side-by-side examination of IL-33-deficient and IL-33 receptor (IL-33R)-deficient mice in the K/BxN serum transfer model, arthritis was ameliorated in the IL-33R knockout (KO) mice but not in the IL-33 KO mice. These findings complement previous knowledge on IL-33R signaling, demonstrating that the IL-33R cross-activates other signaling pathways in addition to IL-33-mediated signals. The results reported by Martin and colleagues in a previous issue of Arthritis Research & Therapy underline the clinical relevance of IL-33R cross-signaling and further illustrate that targeting a cytokine receptor (IL-33R) can have completely different clinical outcomes than targeting the respective cytokine.

Abstract
Psoriatic arthritis is a common chronic inflammatory joint disease in which both inflammation and tissue damage contribute to the patient's outcome. Abnormal activation of the innate and the adaptive immune system contributes to the chronic disease process. Novel insights into these immune pathways are further corroborated by genetic evidence. In this review, we compare the current paradigm of psoriasis to mechanisms that likely play a role in psoriatic arthritis and provide an overview of the role of immune mechanisms in the different features of the disease.

Abstract
Patients with Lyme disease, that is, active infection with Borrelia burgdorferi, experience many types of musculoskeletal complaints, with different explanatory mechanisms. Appropriate therapy depends on understanding the underlying cause of the complaint and addressing that specific root cause. In the case of active infection the dosage, duration, drug, and method of administration of antibiotics should be determined by the state of the infection and history of prior therapy, according to the established and validated recommendations of the Infectious Disease Society of America. Many patients have musculoskeletal complaints not attributable to active infection; some patients have residual complaints following a documented infection that has been adequately treated with antibiotics previously, and others never had true B. burgdorferi infection in the first place. For such patients, antibiotics are not warranted and in fact may be physically and emotionally harmful. Complaints following an episode of Lyme disease are not necessarily due to ongoing infection, especially adequately treated. Consideration of other diagnoses may suggest use of other effective modalities, including physical therapy and emotional support. Appropriate ordering and interpretation of the various validated seroconfirmatory tests available to study B. burgdorferi infection are critical, as these tests are often misapplied and misconstrued in pursuit of strategies aimed at eliminating patients' suffering. Although seronegative Lyme disease has been reported, seronegativity in a reputable laboratory makes the likelihood of Lyme arthritis very low. On the other hand, a positive result from certain unvalidated laboratories or novel assays proves nothing and should not be viewed as substantiating the diagnosis.

Abstract
Men may not be able to multitask, but it is emerging that proteins can. This capacity of proteins to exhibit more than one function is termed protein moonlighting, and, surprisingly, many highly conserved proteins involved in metabolic regulation or the cell stress response have a range of additional biological actions which are involved in bacterial virulence. This review highlights the multiple roles exhibited by a range of bacterial proteins, such as glycolytic and other metabolic enzymes and molecular chaperones, and the role that such moonlighting activity plays in the virulence characteristics of a number of important human pathogens, including Staphylococcus aureus, Streptococcus pyogenes, Streptococcus pneumoniae, Helicobacter pylori, and Mycobacterium tuberculosis.

Abstract
The bottleneck for the induction of collagen-induced arthritis in mice is the recognition of immunodominant type II collagen (CII) peptide (CII259-273) bound to the MHC class II molecule A(q). We have shown previously that the posttranslationally glycosylated lysine at position 264 in this epitope is of great importance for T cell recognition and tolerance induction to CII as well as for arthritis development. The Ncf1 gene, controlling oxidative burst, has been shown to play an important role for immune tolerance to CII. To investigate the effect of oxidation on the efficiency of immune-specific vaccination with MHC class II/glycosylated-CII peptide complexes, we used Ncf1 mutated mice. We demonstrate that normal reactive oxygen species (ROS) levels contribute to the establishment of tolerance and arthritis protection, because only mice with a functional oxidative burst were completely protected from arthritis after administration of the glycosylated CII259-273 peptide in complex with MHC class II. Transfer of T cells from vaccinated mice with functional Ncf1 protein resulted in strong suppression of clinical signs of arthritis in B10.Q mice, whereas the Ncf1 mutated mice as recipients had a weaker suppressive effect, suggesting that ROS modified the secondary rather than the primary immune response. A milder but still significant effect was also observed in ROS deficient mice. During the primary vaccination response, regulatory T cells, upregulation of negative costimulatory molecules, and increased production of anti-inflammatory versus proinflammatory cytokines in both Ncf1 mutated and wild type B10.Q mice was observed, which could explain the vaccination effect independent of ROS.

Abstract
OBJECTIVE S100A8 (calgranulin A, MRP8) and S100A9 (calgranulin B, MRP14) are calcium-binding proteins highly expressed by activated myeloid cells and thought to be involved in the pathogenesis of inflammatory diseases. Circulating levels of S100A8/S100A9 are elevated in both human and experimental models of autoimmune disease, including rheumatoid arthritis (RA). METHODS Mice deficient in S100A9 (S100A9 - /-) and wild-type controls were immunized using standard techniques for the K/BxN serum transfer or the collagen-induced arthritis (CIA) model. RESULTS S100A9 - /- animals, with defective expression of both S100A8 and S100A9 proteins, had similar arthritis and histopathology to that of wild-type controls in both mouse models. CONCLUSION S100A8 and S100A9 are not essential for disease expression in either the K/BxN serum transfer or the CIA model of inflammatory arthritis.

Abstract
Introduction T-helper (Th) lymphocytes are critically required for the pathogenesis of glucose-6-phosphate isomerase (G6PI)-induced arthritis, but neither the G6PI epitopes recognized by arthritogenic T cells nor their pathogenic effector functions have been fully elucidated to date. We aimed at identifying arthritogenic G6PI peptides. Methods We used a library of overlapping peptides spanning the entire G6PI sequence to identify the epitopes recognized by G6PI-specific Th cells. Immunodominant peptides were then used to immunize mice. Arthritis development was evaluated clinically and histologically. The humoral and cellular immune responses upon peptide immunization were analyzed by ELISA and multiparameter flow cytometry, respectively. Results We identified six immunodominant T-cell epitopes in DBA/1 mice, of which three are arthritogenic. One of these peptides (G6PI469–483) is identical in man and mice. Immunization with this peptide induces arthritis, which is less severe and of shorter duration than arthritis induced by immunization with full-length G6PI. Upon immunization with either G6PI or peptide, the antigen-specific Th cells produce IL-17, RANKL, IFNγ and TNFα. Conclusions We identified immunodominant and arthritogenic epitopes of G6PI. Not all immunodominant peptides are arthritogenic. This is the first description of arthritis induced by immunization with a self-peptide in mice.

Abstract
Rheumatoid arthritis (RA) is not only the most severe of all joint diseases but also the most common systemic autoimmune disease affecting approximately 1% of the world-wide adult population. RA is characterized by the presence of autoantibodies in serum and synovial fluid distinguishing the disease from other arthritides such reactive arthritis or osteoarthritis. Since the historical description of rheumatoid factor (RF), which is an autoantibody directed to immunoglobulin G, numerous additional autoantibodies have been discovered in sera of RA patients. These antibodies may be directed to cartilage components, stress proteins, enzymes, nuclear proteins and, most importantly, citrullinated proteins such as fibrin or vimentin. In contrast to other antibodies including RF, anti-citrullinated protein antibodies are targeted almost exclusively by RA patients thus being the most specific serological markers of RA. Even though most other antibodies are not used for diagnostics, they may contribute to the patholophysiology of RA by forming immune complexes in the joint. Furthermore, autoreactive T-cells in serum and synovial fluid may initiate or enhance the disease process via production of proinflammatory cytokines leading to autoantibody secretion, stimulation of macrophages and activation of bone resorbing osteoclasts. Identification of novel autoantigens, particularly citrullinated proteins, and the characterization of the cellular and molecular processes underlying the autoimmune reactions against them has provided new insights into the complex pathogenesis of RA. This has made possible the development of novel therapeutic concepts that may allow to treat the disease more effectively in its early stages where the chances are highest to interrupt the deleterious processes.
