[PMID: 38524279 PMCID: PMC10957380 DOI: 10.1016/j.bbrep.2024.101685] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2023] [Revised: 02/10/2024] [Accepted: 03/09/2024] [Indexed: 03/26/2024] Open
Abstract
The migration of vascular smooth muscle cells (VSMCs) is one of the most important events in the remodeling of atherosclerosis plaque. The aim of study was to investigate the role of Heparin in the VSMC migration and its association with the NF-kB, collagen 1 and collagen 3 expression levels. Moreover, the incorporation of Heparin was studied in the VSMC cultures including Betulinic acid and Ibrutinib. Twelve cell groups were cultured and treated with the Heparin, Betulinic acid and Ibrutinib based on the viability and toxicity in 24-h and 48-h periods. The gene and protein expression levels were measured by RT-qPCR and western blotting techniques. The VSMC migration was determined by scratch test. In contrast with Ibrutinib (2 μM), Heparin (30 IU) increased significantly (P < 0.05) the NF-kB gene and protein expression levels and the VSMC migration during the exposure periods. Heparin (15 IU and 30 IU) also increased the collagen 1 gene expression level in the 48-h period while Heparin (5 IU and 15 IU) increased the collagen 3 gene expression levels in both periods. Incorporating Heparin into the cultures including Betulinic acid and Ibrutinib affected the collagen 1 and collagen 3 expression levels. The data suggested that the cell migration relates to NF-kB in the VSMCs treated with Heparin and Ibrutinib. Furthermore, the Heparin doses (5 IU and 15 IU) were safe for VSMCs based on the NF-kB, and collagen 3 expression levels.

Abstract
Systemic stem cell therapies hold promise for treating severe diseases, but their efficiency is hampered by limited migration of injected stem cells across vascular endothelium towards diseased tissues. Understanding transendothelial migration is crucial for improving therapy outcomes. We propose a novel 3Din vitrovessel model that aids to unravel these mechanisms and thereby facilitates stem cell therapy development. Our model simulates inflammation through cytokine diffusion from the tissue site into the vessel. It consists of a biofabricated vessel embedded in a fibrin hydrogel, mimicking arterial wall composition with smooth muscle cells and fibroblasts. The perfusable channel is lined with a functional endothelium which expresses vascular endothelial cadherin, provides an active barrier function, aligns with flow direction and is reconstructed byin situtwo-photon-microscopy. Inflammatory cytokine release (tumor necrosis factorα, stromal-derived factor (1) is demonstrated in both a transwell assay and the 3D model. In proof-of-principle experiments, mesoangioblasts, known as a promising candidate for a stem cell therapy against muscular dystrophies, are injected into the vessel model, showing shear-resistant endothelial adhesion under capillary-like flow conditions. Our 3Din vitromodel offers significant potential to study transendothelial migration mechanisms of stem cells, facilitating the development of improved stem cell therapies.

Abstract
This study was designed to investigate the correlation of neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), and interleukin (IL)-37/IL-17 ratio with the incidence/treatment of rheumatoid arthritis (RA). Firstly, fifty-eight patients with RA treated at the first affiliated hospital of Xinjiang Medical University from January 2018 to January 2019 were selected as the RA group; forty-nine healthy volunteers were enrolled in the control group. RA patients were treated with disease-modifying anti-rheumatic drugs (DMARDs). Next, the NLR, PLR, IL-37, IL-17 and 28-joint disease activity score using erythrocyte sedimentation rate (DAS28-ESR) were deleted in two groups. Subsequently, Spearman correlation analysis was adopted for the correlations of various indicators before and after treatment in two groups. According to the analysis results, the levels of NLR, PLR, IL-37, and IL-17 before treatment in the RA group were higher than those in the control group (P < .05), but the difference in the IL-37/IL-17 level between the two groups was not significant (P > .05). After treatment, NLR, PLR, and IL-37/IL-17 levels were significantly reduced in RA patients (P < .05). NLR and PLR were significantly positively correlated with DAS28-ESR, ESR and C-reactive protein (CRP), of which represented the disease activity of RA. NLP was strongly correlated with IL-37/IL-17. Collectively, NLR, PLR, IL-37, and IL-17 are closely related to the occurrence of RA. In addition, NLR and IL-37/IL-17 are more suitable than PLR in reflecting the therapeutic effect. Therefore, IL-37/IL-17 can be considered as a new indicator for reflecting the treatment effectiveness of RA.

Abstract
Heparin has been used extensively as an antithrombotic and anticoagulant for close to 100 years. This anticoagulant activity is attributed mainly to the pentasaccharide sequence, which potentiates the inhibitory action of antithrombin, a major inhibitor of the coagulation cascade. More recently it has been elucidated that heparin exhibits anti-inflammatory effect via interference of the formation of neutrophil extracellular traps and this may also contribute to heparin's antithrombotic activity. This illustrates that heparin interacts with a broad range of biomolecules, exerting both anticoagulant and nonanticoagulant actions. Since our previous review, there has been an increased interest in these nonanticoagulant effects of heparin, with the beneficial role in patients infected with SARS2-coronavirus a highly topical example. This article provides an update on our previous review with more recent developments and observations made for these novel uses of heparin and an overview of the development status of heparin-based drugs. SIGNIFICANCE STATEMENT: This state-of-the-art review covers recent developments in the use of heparin and heparin-like materials as anticoagulant, now including immunothrombosis observations, and as nonanticoagulant including a role in the treatment of SARS-coronavirus and inflammatory conditions.

Abstract
Unfractionated heparin (UFH) and enoxaparin (Enox) were substituted with a photoswitch (PS) showing quantitative trans-cis and cis-trans photoisomerizations. Long half-life of the cis photoisomer enabled comparison of the properties of heparins substituted with both PS photoisomers. Hydrodynamic diameter, Dh, of UFH-PS decreased upon trans-cis photoisomerization, the change being more pronounced for UFH-PS with a higher degree of substitution (DS), while Dh of Enox-PS did not significantly change. The anticoagulative properties of substituted heparins were significantly attenuated compared to non-substituted compounds. The interaction of UFH-PS with HSA, lysozyme, and protamine was studied with ITC. Under serum-free conditions, UFH-PS-trans with a high DS stimulated proliferation of murine fibroblasts, while UFH-PS-cis decreased the viability of these cells. Under serum conditions, both UFH-PS-cis and UFH-PS-trans decreased cell viability, the reduction for UFH-PS-cis being higher than that for UFH-PS-trans. Neither Enox-PS-trans nor Enox-PS-cis influenced the viability at concentrations prolonging aPTT, while at higher concentrations their cytotoxicity did not differ.

Abstract
The autoimmune disorder rheumatoid arthritis (RA) is a relapsing and chronic inflammatory disease that affects the synovial cells, cartilage, bone, and muscle. It is characterised by the accumulation of huge numbers of polymorphonuclear neutrophils (PMNs) and macrophages in the synovia. Auto-antibodies are deposited in the joint via the activity of highly cationic histones released from neutrophil extracellular traps (NETs) in a phenomenon termed NETosis. The cationic histones function as opsonic agents that bind to negatively charged domains in autoantibodies and complement compounds via strong electrostatic forces, facilitating their deposition and endocytosis by synovial cells. However, eventually the main cause of tissue damage is the plethora of toxic pro-inflammatory substances released by activated neutrophils recruited by cytokines. Tissue damage in RA can also be accompanied by infections which, upon bacteriolysis, release cell-wall components that are toxic to tissues. Some amelioration of the damaged cells and tissues in RA may be achieved by the use of highly anionic heparins, which can neutralize cationic histone activity, provided that these polyanions are co-administrated with anti-inflammatory drugs such as steroids, colchicine, or methotrexate, low molecular weight antioxidants, proteinase inhibitors, and phospholipase A2 inhibitors.

Abstract
Endoplasmic reticulum (ER) stress associated proteins contribute to the pathogenesis of rheumatoid arthritis (RA) through affecting synoviocyte proliferation and proinflammatory cytokine production. The role of DERL3, an ER-associated degradation component, in joint inflammation of RA was explored. Synovial tissues from RA and osteoarthritis (OA) patients were collected, and in RA synovial tissue, DERL3 showed up-regulation and significantly positive correlation with the expression of tumor necrosis factor alpha (TNF-α), interleukin (IL)-6 and matrix metalloproteinase (MMP)-1. Immunofluorescence result suggested DERL3 was located in fibroblast-like synoviocytes (FLS). Among different inflammatory stimuli, DERL3 could be up-regulated by TNF-α stimulation in FLS. Under TNF-α stimulation, knocking down DERL3, the expression of IL-6, IL-8, MMP-1, MMP-13 was reduced and the activation of nuclear factor kappa B (NF-κB) signaling pathway was inhibited. In pristane-induced arthritis (PIA) rat model, Derl3 was up-regulated in synovial tissue and disease was attenuated after intraarticular injection of siDerl3. Overall, we conclude that TNF-α inducing DERL3 expression promotes the inflammation of FLS through activation of NF-κB signaling pathway, suggesting DERL3 plays important roles in the pathogenesis of RA and is a promising therapeutic target.

Abstract
Apoptotic resistance and excessive proliferation of rheumatoid arthritis fibroblast-like synoviocytes (RA-FLSs) stimulated by inflammation could lead to distal joint destruction and bone damage. Periplocin could promote apoptosis, resist proliferation, and reduce inflammation. However, the effect and mechanism toward periplocin in proliferation and inflammation of RA-FLSs remain unclear. The role of tumor necrosis factor (TNF)-α induced proliferation and expression of inflammatory cytokines in RA-FLSs was established. Our studies noted that cell viability of TNF-α-induced RA-FLSs was inhibited in periplocin treatment via dose-response, whereas cell apoptosis of RA-FLSs was triggered by dose-dependent effect of periplocin. Bcl-2 protein, one of the apoptotic regulators, was downregulated, while other regulators of apoptosis, including BAX, cleaved caspase-3, and cleaved caspase-9, were upregulated in RA-FLSs under periplocin treatment. In addition, periplocin decreased the TNF-α-induced mRNA and protein expression levels of interleukin (IL)-1β and IL-6 in RA-FLSs in a dose-dependent way. Finally, the increased levels of phospho (p)-inhibitor of kappa B (IκBα)/IκBα and p-NF (nuclear factor)-κB/nuclear factor kappa B (NF-κB) ratio of RA-FLSs stimulated by TNF-α were decreased by periplocin treatment. Taken together, periplocin treatment decreased cell viability and cytokines expression and promoted cell apoptosis of TNF-α-induced RA-FLSs through inhibition of NF-κB signaling pathway, providing a potential therapeutic approach for RA.

[PMID: 32565114 DOI: 10.1016/j.imlet.2020.06.010] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2020] [Revised: 05/30/2020] [Accepted: 06/16/2020] [Indexed: 01/20/2023]
Abstract
The purpose of the experiment was to explore the effect of Ganoderic acid A (GAA) on adjuvant-induced arthritis in rats. In this study, the rat model of collagen-induced rheumatoid arthritis (CIA) was established with type II collagen plus Freund's complete adjuvant. Arthritis index, joint pathology, toe swelling, hemorheology, synovial cell apoptosis, related cytokines and JAK3/STAT3 and nuclear factor-κB (NF-κB) signaling pathway were measured in rats. We found that GAA can significantly inhibit the arthritis index, improve joint pathology, reduce toe swelling, improve blood rheology, improve synovial cell apoptosis, and restore related cytokine negative regulation JAK3/STAT3 and NF-κB signaling pathways. In conclusion, GAA has an obvious therapeutic effect on joint inflammation of toes in CIA model rats, which may be due to the regulation of JAK3/STAT3 and NF-κB signaling pathway.

Abstract
Recent data have implicated inflammation of the cerebrospinal fluid spaces after subarachnoid, intraventricular, and intracerebral hemorrhage to be a critical driver of multiple secondary brain injuries such as hydrocephalus, cerebral edema, and vasospasm. While TLR4-dependent reparative inflammation is an important protective response that can eliminate physical irritants and damaged cells, sustained or inappropriately triggered inflammation can initiate or propagate disease.Areas covered: We review recent advances in our understanding of how TLR4, including its upstream damage-associated molecular patterns and its downstream MyD88-dependent and independent signaling pathways, contributes to hemorrhage-induced inflammation in numerous brain diseases. We discuss prospects for the pharmacotherapeutic targeting of TLR4 in these disorders, including the use of repurposed FDA-approved agents.Expert opinion: TLR4 inhibitors with good blood-brain-barrier (BBB) penetration could be useful adjuncts in post-hemorrhagic hydrocephalus and multiple other diseases associated with brain hemorrhage and inflammation.

J Biomed Mater Res A 2020; 108:1099-1111. [PMID: 31967394 DOI: 10.1002/jbm.a.36885] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2019] [Revised: 01/07/2020] [Accepted: 01/10/2020] [Indexed: 12/12/2022]
Abstract
Inflammation and subsequent fibrotic encapsulation that occur after implantation of biomaterials are issues that fostered efforts in designing novel biocompatible materials to modulate the immune response. In this study, glycosaminoglycans (GAG) like hyaluronic acid (HA) and heparin (Hep) that possess anti-inflammatory activity were covalently bound to NH2 -modified surfaces using EDC/NHS cross-linking chemistry. Immobilization and physical surface properties were characterized by atomic forces microscopy, water contact angle studies and streaming potential measurements demonstrating the presence of GAG on the surfaces that became more hydrophilic and negatively charged compared to NH2 -modified. THP-1 derived macrophages were used here to study the mechanism of action of GAG to affect the inflammatory responses illuminated by studying macrophage adhesion, the formation of multinucleated giant cells (MNGCs) and IL-1β release that were reduced on GAG-modified surfaces. Detailed investigation of the signal transduction processes related to macrophage activation was performed by immunofluorescence staining of NF-κB (p65 subunit) together with immunoblotting. We studied also association and translocation of FITC-labeled GAG. The results show a significant decrease in NF-κB level as well as the ability of macrophages to associate with and take up HA and Hep. These results illustrate that the anti-inflammatory activity of GAG is not only related to making surfaces more hydrophilic, but also their active involvement in signal transduction processes related to inflammatory reactions, which may pave the way to design new anti-inflammatory surface coatings for implantable biomedical devices.

TL1A/TNFR2-mediated mitochondrial dysfunction of fibroblast-like synoviocytes increases inflammatory response in patients with rheumatoid arthritis via reactive oxygen species generation. FEBS J 2020; 287:3088-3104.

Abstract
Rheumatoid arthritis (RA) is the major autoimmune destructive disease of joints with a complicated pathogenesis. The contribution of tumor necrosis factor-like ligand 1A (TL1A) in RA pathogenesis, especially on fibroblast-like synoviocytes (FLS), has been suggested clinically. The present study investigated the role of TL1A in mitochondrial dysfunction, induced oxidative stress in mitochondria, apoptosis resistance and the inflammatory response in FLS obtained from RA patients (RA-FLS). RA-FLS were incubated with TL1A and tumor necrosis factor receptor 2 (TNFR2) antagonist. Respiratory function, mitochondrial membrane potential and respiration associated genes of mitochondria were measured in both TL1A stimulated and non-stimulated RA-FLS. Additionally, the effects of TL1A on reactive oxygen species (ROS) production in mitochondria, apoptosis and the inflammatory response in RA-FLS were also assessed. The role of TL1A in association between ROS generation, especially mitochondrial type and the inflammatory response, was evaluated by measuring inflammation-related cytokines and signaling pathways using ROS inhibitors, diphenyleneiodonium chloride and Mito-TEMPO (Sigma-Aldrich, Miamisburg, OH, USA). We found that TL1A induced mitochondrial dysfunction by weakening mitochondrial respiration and membrane potential, which was blocked by a TNFR2 antagonist. Increased ROS synthesis in impaired mitochondria was observed with MitoSOX (Invitrogen, CA, USA) immunofluorescence staining in TL1A-stimulated RA-FLS but inhibited by a TNFR2 antagonist. TL1A influenced apoptosis resistance and inflammatory mediators via TNFR2. Inhibition of mitochondria-derived ROS compromised the production of inflammatory factors in TL1A-stimulated RA-FLS, suggesting that mitochondrial dysfunction mediated by the TL1A/TNFR2 axis might amplify the inflammatory response via regulation of mitochondria-derived ROS generation. Collectively, our results reveal that TL1A might be involved in making FLS more aggressive in RA pathogenesis via cell respiration interruption.

Abstract
Rheumatoid arthritis (RA) is a common chronic autoimmune disease and effective treatment for RA is still lacking. In this study, the regulatory role of miR-19a-3p in RA was investigated. Quantitative polymerase chain reaction analysis of human blood samples showed that the level of miR-19a-3p was significantly lower in the RA patients compared with that in healthy patients (P < 0.05). In RA fibroblast-like synoviocytes (RAFLS), miR-19a-3p and suppressor of cytokine signaling 3 (SOCS3) were also downregulated and upregulated, respectively, compared with those of normal FLS. Transfection of miR-19a-3p mimic in RAFLS inhibited cell proliferation and promoted cell apoptosis. TargetScan identified SOCS3 as a target of miR-19a-3p, which was confirmed by dual-luciferase assay. Western blot indicated that SOCS3 protein level was significantly decreased after miR-19a-3p overexpression. Moreover, SOCS3 silencing through siRNA transfection also enhanced cell proliferation, meanwhile inhibiting RAFLS apoptosis. In addition, SOCS3 overexpression abrogated the effects of miR-19a-3p overexpression on cell proliferation and apoptosis, corroborating that SOCS3 acts as a downstream effector in the miR-19a-3p-mediated function of RAFLS. These findings suggest that miR-19a-3p plays an important role in RA, and the miR-19a-3p/SOCS3 axis may become a potential therapeutic target for RA.

Abstract
Rheumatoid arthritis fibroblast-like synoviocytes play an essential role in the occurrence and progression of rheumatoid arthritis. As the main pharmacologically active components of Aralia taibaiensis, total saponins, particularly triterpenoid saponins, have been shown to possess multiple pharmacological activities including relieving rheumatism. However, the effect of araloside A, a triterpenoid saponin extracted from the root bark of Aralia taibaiensis, on rheumatoid arthritis remains unknown. Cell counting kit-8 assay was employed to determine cell viability. Flow cytometry analysis, caspase-3/7 activity assay and Western blot analysis of cytochrome c and B-cell lymphoma 2 were conducted to evaluate cell apoptosis. Inflammation was assessed by detecting the production of inflammatory cytokines including interleukin-6 and interleukin-8, as well as inflammatory mediators including nitric oxide and prostaglandin E2. The changes of the nuclear factor kappa B pathway were examined by Western blot. Results showed that araloside A concentration-dependently inhibited the proliferation of MH7A cells. Meanwhile, araloside A dose-dependently augmented the apoptotic rate and caspase-3/7 activity, increased cytochrome c level and decreased B-cell lymphoma 2 level in MH7A cells. Araloside A concentration-dependently curbed the production of interleukin-6, interleukin-8, prostaglandin E2 and nitric oxide in MH7A cells. In addition, we found that araloside A inhibited the nuclear factor kappa B pathway and inhibition of the nuclear factor kappa B pathway by BAY11-7082 and PDTC showed a similar role to araloside A in MH7A cells. Taken together, araloside A exerted pro-apoptotic and anti-inflammatory effects in rheumatoid arthritis fibroblast-like synoviocytes via inhibition of the nuclear factor kappa B pathway.

Abstract
Mast cells are tissue-resident cells of the innate immunity, implicated in the pathogenesis of many autoimmune diseases, including rheumatoid arthritis (RA). They are present in synovia and their activation has been linked to the potentiation of inflammation in the course of RA. However, recent investigations questioned the role of mast cells in arthritis. In particular, animal models generated conflicting results, so that many of their pro-inflammatory, i.e. pro-arthritogenic functions, even though supported by robust experimental evidence, have been labelled as redundant. At the same time, a growing body of evidence suggests that mast cells can act as tunable immunomodulatory cells. These characteristics, not yet fully understood in the context of RA, could partially explain the inconsistent results obtained with experimental models, which do not account for the pro- and anti-inflammatory functions exerted in more chronic heterogeneous conditions such as RA. Here we present an overview of the current knowledge on mast cell involvement in RA, including the intriguing hypothesis of mast cells acting as subtle immunomodulatory cells and the emerging concept of synovial mast cells as potential biomarkers for patient stratification.
