Sun HG, Jiang Q, Fan WJ, Shen XY, Wang ZW, Wang X. TAGAP activates Th17 cell differentiation by promoting RhoA and NLRP3 to accelerate rheumatoid arthritis development. Clin Exp Immunol 2023; 214:26-35. [PMID: 37458218 PMCID: PMC10711349 DOI: 10.1093/cei/uxad084] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2023] [Revised: 07/06/2023] [Accepted: 07/16/2023] [Indexed: 12/18/2023] Open
Abstract
Rheumatoid arthritis (RA) is a chronic autoimmune disorder that can give rise to joint swelling and inflammation, potentially affecting the entire body, closely linked to the state of T cells. The T-cell activation Rho GTPase activating protein (TAGAP) is associated with many autoimmune diseases including RA and is directly linked to the differentiation of Th17 cells. The present study intends to investigate the influence of TAGAP on the RA progression and its mechanism to empower new treatments for RA. A collagen-induced-arthritis (CIA) rat model was constructed, as well as the extraction of CD4+ T cells. RT-qPCR, H&E staining and safranin O/fast green staining revealed that TAGAP interference reduced TAGAP production in the ankle joint of CIA rats, and joint inflammation and swelling were alleviated, which reveals that TAGAP interference reduces synovial inflammation and cartilage erosion in the rat ankle joint. Expression of inflammatory factors (TNF-α, IL-1β, and IL-17) revealed that TAGAP interference suppressed the inflammatory response. Expression of pro-inflammatory cytokines, matrix-degrading enzymes, and anti-inflammatory cytokines at the mRNA level was detected by RT-qPCR and revealed that TAGAP interference contributed to the remission of RA. Mechanistically, TAGAP interference caused a significant decrease in the levels of RhoA and NLRP3. Assessment of Th17/Treg levels by flow cytometry revealed that TAGAP promotes Th17 cells differentiation and inhibits Treg cells differentiation in vitro and in vivo. In conclusion, TAGAP interference may decrease the differentiation of Th17 cells by suppressing the expression of RhoA and NLRP3 to slow down the RA progression.

Abstract
Rheumatoid arthritis (RA) is the most common chronic autoimmune disease worldwide. Although progress has been made in RA treatment in recent decades, remission cannot be effectively achieved for a considerable proportion of RA patients. Thus, novel potential targets for therapeutic strategies are needed. Semaphorin 5A (SEMA5A) plays a pivotal role in RA progression by facilitating pannus formation, and it is a promising therapeutic target. In this study, we sought to develop an antibody treatment strategy targeting SEMA5A and evaluate its therapeutic effect using a collagen-induced arthritis (CIA) model. We generated SYD12-12, a fully human SEMA5A blocking antibody, through phage display technology. SYD12-12 intervention effectively inhibited angiogenesis and aggressive phenotypes of RA synoviocytes in vitro and dose-dependently inhibited synovial hyperplasia, pannus formation, bone destruction in CIA mice. Notably, SYD12-12 also improved the Treg/Th17 imbalance in CIA mice. We confirmed through immunofluorescence and molecular docking that SYD12-12 integrated with the unique TSP-1 domain of SEMA5A. In conclusion, we developed and characterized a fully human SEMA5A-blocking antibody for the first time. SYD12-12 effectively alleviated disease progression in CIA mice by inhibiting pannus formation and improving the Treg/Th17 imbalance, demonstrating its potential for the RA treatment.

Abstract
Rheumatoid arthritis (RA) is a type of arthritis autoimmune disease characterized by systemic chronic inflammation. C-C Chemokine ligand 20 (CCL20) is the same as most chemokines with immunomodulatory and inflammatory processes. The correlation of CCL20 in RA remains unclear. This study aimed to explore the association among levels of CCL20, T helper cell (TH) subset (Th1/Th2/Th17)-related cytokine levels, and clinical indices of RA disease activity. Serum CCL20 levels were quantified by enzyme-linked immunosorbent assay, and a flow-fluorescence technique was used to assess Th1/Th2/Th17-related cytokine levels. The serum CCL20 levels in patients were significantly higher than those in healthy controls and positively associated with C-reactive protein levels, erythrocyte sedimentation rate, and disease activity score-28 (DAS28). Patients with RA were categorized into 4 major groups, including remission, low, moderate, and high disease activity, with related DAS28 scores for each group. CCL20 levels of the disease moderate/high activity group were moderately positively correlated with IL-6 levels, but not with the other Th1/Th2/Th17-related cytokines. Serum CCL20 levels correlate strongly with RA disease activity and clinical inflammation and were significantly elevated in patients compared to healthy individuals. CCL20 plays a key role in the immune response of patients with RA and is, therefore, a potential biomarker of disease activity.

Abstract
Hemophagocytic Lymphohistiocytosis (HLH) is a group of disorders culminating in systemic inflammation and multi-organ failure with high incidence of hepatic dysfunction. Overproduction of IFN-γ is the main immunopathological driver in this disorder. Monokine induced by IFN-γ (CXCL9) serves as a biomarker for disease activity and response to treatment in this disorder. However, very little is understood about the actual functional role of CXCL9 in pathogenesis in HLH. In the current study, we sought to determine the role of CXCL9 in pathogenesis in murine models of both Familial HLH (prf1-/-) and Toll Like Receptor (TLR) 9 repeated stimulation induced Macrophage Activation Syndrome (MAS), a form of secondary HLH. FHL and MAS were induced in both CXCL9 genetically deficient mice (cxcl9-/-) and controls as well as using AMG487, a pharmacological antagonist of the CXCL9 receptor, CXCR3. Results showed that CXCL9 genetic deficiency did not improve disease parameters or hepatitis in both models. Consistent with genetic ablation of CXCL9, inhibition of its receptor, CXCR3, by AMG487 did not show any significant effects in the FHL model. Taken together, inhibition of CXCL9-CXCR3 interaction does not ameliorate HLH physiology in general, or hepatitis as a classical target organ of disease.

CXCR3 antagonist NBI-74330 mitigates joint inflammation in Collagen-Induced arthritis model in DBA/1J mice. Int Immunopharmacol 2023; 118:110099. [PMID: 37018975 DOI: 10.1016/j.intimp.2023.110099] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2022] [Revised: 03/20/2023] [Accepted: 03/23/2023] [Indexed: 04/05/2023]
Abstract
Rheumatoid arthritis (RA) is a chronic inflammatory disease characterized by uncontrolled synovial proliferation, pannus formation, cartilage injury, and bone destruction. We used the CXCR3-specific antagonist NBI-74330 to block T-cell-mediated signaling in a DBA/1J mouse model of collagen-induced arthritis (CIA). After CIA induction, DBA/1J mice were treated with NBI-74330 (100 mg/kg) daily from day 21 until day 34 and evaluated for arthritic score and histopathological changes. Furthermore, using flow cytometry, we investigated the effects of NBI-74330 on Th1 (IFN-γ, TNF-α, T-bet, STAT4, Notch-3, and RANKL), Th17 (IL-21, IL-17A, STAT3, and RORγt), and Th22 (IL-22) cells in splenic CD4+ and CXCR3+T-cells. We also used RT-PCR to assess the effect of mRNA levels of IFN-γ, TNF-α, T-bet, RANKL, IL-17A, RORγt, and IL-22 in knee tissues. The IFN-γ, TNF-α, and IL-17A serum protein levels were measured using ELISA. Compared to vehicle-treated CIA mice, the severity of arthritic scores and histological severity of inflammation decreased significantly in NBI-74330-treated CIA mice. Moreover, compared to vehicle-treated CIA mice, the percentages of CD4+IFN-γ+, CD4+TNF-α+, CD4+T-bet+, CD4+STAT4+, CD4+Notch-3+, CXCR3+IFN-γ+, CXCR3+TNF-α+, CXCR3+T-bet+, CXCR3+STAT4+, CXCR3+Notch-3+, CD4+RANKL+, CD4+IL-21+, CD4+IL-17A+, CD4+STAT3+, CD4+RORγt+, and CD4+IL-22+ cells decreased in NBI-74330-treated CIA mice. Furthermore, NBI-74330-treatment downregulated IFN-γ, TNF-α, T-bet, RANKL, STAT3, IL-17A, RORγt, and IL-22 mRNA levels. Serum IFN-γ, TNF-α, and IL-17A levels were significantly lower in NBI-74330-treated CIA mice than in vehicle-treated CIA mice. This study demonstrates the antiarthritic effects of NBI-74330 in CIA mice. Therefore, these data suggest that NBI-74330 could be considered a potential RA treatment.

Abstract
Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by a high level of autoantibody production. T follicular helper (Tfh) cells and B cells participate in the development of SLE. Several studies have shown that CXCR3+ cells are increased in SLE patients. However, the mechanism through which CXCR3 influences lupus development remains unclear. In this study, we established lupus models to determine the role of CXCR3 in lupus pathogenesis. The concentration of autoantibodies was detected using the enzyme-linked immunosorbent assay (ELISA), and the percentages of Tfh cells and B cells were measured using flow cytometry. RNA sequencing (RNA-seq) was performed to detect the differentially expressed genes in CD4+ T cells from wild-type (WT) and CXCR3 knock-out (KO) lupus mice. Migration of CD4+ T cells in spleen section was assessed using immunofluorescence. CD4+ T cell function in helping B cells produce antibodies was determined using a co-culture experiment and supernatant IgG ELISA. Lupus mice were treated with a CXCR3 antagonist to confirm the therapeutic effects. We found that the expression of CXCR3 was increased in CD4+ T cells from lupus mice. CXCR3 deficiency reduced autoantibody production with decreased proportions of Tfh cells, germinal center (GC) B cells, and plasma cells. Expression of Tfh-related genes was downregulated in CD4+ T cells from CXCR3 KO lupus mice. Migration to B cell follicles and T-helper function of CD4+ T cells were reduced in CXCR3 KO lupus mice. CXCR3 antagonist AMG487 decreased the level of serum anti-dsDNA IgG in lupus mice. We clarify that CXCR3 may play an important role in autoantibody production by increasing the percentages of aberrant activated Tfh cells and B cells and promoting the migration and T-helper function of CD4+ T cells in lupus mice. Thus, CXCR3 may be a potential target for lupus therapy.

Abstract
Chemokines are pivotal players in instigation and perpetuation of synovitis through leukocytes egress from the blood circulation into the inflamed articulation. Multitudinous literature addressing the involvement of the dual-function interferon (IFN)-inducible chemokines CXCL9, CXCL10 and CXCL11 in diseases characterized by chronic inflammatory arthritis emphasizes the need for detangling their etiopathological relevance. Through interaction with their mutual receptor CXC chemokine receptor 3 (CXCR3), the chemokines CXCL9, CXCL10 and CXCL11 exert their hallmark function of coordinating directional trafficking of CD4+ TH1 cells, CD8+ T cells, NK cells and NKT cells towards inflammatory niches. Among other (patho)physiological processes including infection, cancer, and angiostasis, IFN-inducible CXCR3 ligands have been implicated in autoinflammatory and autoimmune diseases. This review presents a comprehensive overview of the abundant presence of IFN-induced CXCR3 ligands in bodily fluids of patients with inflammatory arthritis, the outcomes of their selective depletion in rodent models, and the attempts at developing candidate drugs targeting the CXCR3 chemokine system. We further propose that the involvement of the CXCR3 binding chemokines in synovitis and joint remodeling encompasses more than solely the directional ingress of CXCR3-expressing leukocytes. The pleotropic actions of the IFN-inducible CXCR3 ligands in the synovial niche reiteratively illustrate the extensive complexity of the CXCR3 chemokine network, which is based on the intercommunion of IFN-inducible CXCR3 ligands with distinct CXCR3 isoforms, enzymes, cytokines, and infiltrated and resident cells present in the inflamed joints.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Gout belongs to the category of "arthralgia syndrome" in traditional Chinese medicine. It is believed that gout is caused by stagnation of blood stasis, heat, and turbid toxin. Qingre Huazhuo Jiangsuan Decoction (QHJD) is a traditional Chinese medicine prescription developed from the classic Chinese medicine prescription Simiao powder to clear heat, remove turbidity, reduce acid, and reduce inflammation. Now Traditional Chinese Medicine (TCM) physicians often apply it to treat acute gouty arthritis (AGA). However, the mechanism of QHJD in relieving acute gouty arthritis is still unclear, and further research is needed. AIM OF THE STUDY Here, we aim to explore the potential mechanism of QHJD in relieving acute gouty arthritis. MATERIALS AND METHODS Acute gouty arthritis model was established by injecting monosodium urate (MSU) suspension into knee joint. The pathological state of synovial tissue in each group was evaluated by hematoxylin-eosin (HE) staining. The level of TNF-α, IL-6, and IL-1β were detected by enzyme-linked immunosorbent assay (ELISA). qRT-PCR was used to detect the mRNA expression of NLRP3, ATG5, ATG7, PI3K, AKT, and mTOR. The protein expression of LC3II/I, p62, ULK1, P-ULK1, Beclin-1, PI3K, AKT, mTOR, P-PI3K, P-AKT, and P-mTOR were detected by Western blot. RESULTS (1) The level of autophagy protein (mRNA) was significantly up-regulated in QHJD group and rapamycin, while the expression of autophagy protein (mRNA) was significantly downregulated in the 3-methyladenoenoic acid (3 MA) group; (2) QHJD and rapamycin significantly inhibited PI3K/AKT/mTOR pathway, while 3 MA group activated this pathway. (3) It was worth noting that after treatment with QHJD and rapamycin, the inflammatory pathological state of AGA synovial tissue was significantly reduced with the activation of the autophagy gene in knee synovial tissue, and the inhibition of PI3K/AKT/mTOR pathway. CONCLUSIONS This research revealed that QHJD activates autophagy by inhibiting PI3K/AKT/mTOR pathway, thereby relieving acute gouty arthritis.

CXCR3 antagonist AMG487 ameliorates experimental autoimmune prostatitis by diminishing Th1 cell differentiation and inhibiting macrophage M1 phenotypic activation. Prostate 2022; 82:1223-1236. [PMID: 35700340 DOI: 10.1002/pros.24395] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/12/2021] [Revised: 04/16/2022] [Accepted: 05/16/2022] [Indexed: 11/06/2022]
Abstract
BACKGROUND Chronic prostatitis and chronic pelvic pain syndrome (CP/CPPS) is an inflammatory immune disease that is characterized by infiltrating inflammatory cells in the prostate and pelvic or by perineal pain. Receptor CXCR3modulates immune and inflammatory responses; however, the effects of CXCR3 antagonist AMG487 in the context of CP/CPPS are unknown. Therefore, we investigated the effect of AMG487 in experimental autoimmune prostatitis (EAP) mice and explored the potential functional mechanisms. METHODS The EAP model was induced by intradermally injecting a mixture of prostate antigens and complete Freund's adjuvant on Days 0 and 28. To evaluate the effect of AMG487 on EAP mice, treatment with AMG487 and vehicle solution was conducted for the indicated period. Then, procedures were performed, including behavioral test, to evaluate the pain response to stimulation before the mice were killed and a histological assessment to evaluate the inflammation after the mice were killed. Immunofluorescence, flow cytometry, and Western blot assay were used to analyze the functional phenotype and regulation mechanism of AMG487 on T helper type 1 (Th1) cells and macrophages. RESULTS We found high expression of CXCR3 in human benign prostate tissues with inflammation and EAP mice. The elevated CXCR3 in prostate tissues correlates with the severity of inflammation. CXCR3 antagonist AMG487 treatment ameliorated the inflammatory changes and the pelvic pain of EAP mice. AMG487 inhibits Th1 cell differentiation through the IL-12/STAT4pathway and inhibits pro-inflammatory M1 macrophages through the lipopolysaccharide/NF-κB p65signaling. AMG487 could inhibit the secretion of inflammatory mediators in EAP mice. CONCLUSION CXCR3 antagonist AMG487 could ameliorate the inflammatory changes and the pelvic pain of EAP mice by diminishing Th1 cell differentiation and inhibiting macrophage M1 phenotypic activation. Thus, the results imply that AMG487 has the potential as an effective therapeutic agent in the prevention and treatment of EAP.

Moxibustion regulates T-regulatory/T-helper 17 cell balance by modulating the microRNA-221/suppressor of cytokine signaling 3 axis in a mouse model of rheumatoid arthritis. JOURNAL OF INTEGRATIVE MEDICINE 2022; 20:453-462. [PMID: 35729047 DOI: 10.1016/j.joim.2022.06.002] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/10/2022] [Accepted: 05/30/2022] [Indexed: 06/15/2023]
Abstract
OBJECTIVE Rheumatoid arthritis (RA) progression is associated with the balance of T-regulatory (Treg) and T-helper 17 (Th17) cells, while the role of microRNAs (miRs) in regulating Treg/Th17 cell balance has not been clarified. This study aimed to assess whether moxibustion could regulate Treg/Th17 cell balance by modulating the miR-221/suppressor of cytokine signaling 3 (SOCS3) axis in the RA mouse model. METHODS A mouse model of collagen-induced arthritis (CIA) was established in male DBA/1J mice. Twenty-two days after CIA induction, the mice received daily treatment with moxibustion for 12 times. Pathological scores were assessed according to the levels of synovial hyperplasia. The expression levels of cytokines interleukin (IL)-1β, IL-6, tumor necrosis factor-α (TNF-α), interferon-γ (IFN-γ), IL-17 and IL-10 were analyzed in serum by enzyme-linked immunosorbent assay. The cluster of differentiation 4 (CD4+) splenocytes was analyzed by fluorescence-activated cell sorting. The expression levels of RA-related miRs and target genes were subsequently detected, and the target of miR-221 was confirmed by the dual-luciferase reporter assay. RESULTS It was revealed that moxibustion treatment decreased the pathological scores and downregulated the expression levels of IL-1β, IL-6, TNF-α, IFN-γ and IL-17, while upregulated the expression level of IL-10. The Treg/Th17 cell balance was regulated by moxibustion treatment. The expression level of miR-221 was suppressed by moxibustion treatment. Furthermore, SOCS3 was found as the direct target of miR-221, which mediated the function of moxibustion by regulating the Treg/Th17 cell balance. CONCLUSION Moxibustion therapy regulated the Treg/Th17 cell balance by modulating the miR-221/SOCS3 axis in the RA mouse model.

Abstract
OBJECTIVES This experimental study was carried out to investigate the effects of locally delivered nanoparticles (AMG-487 NP) containing a CXCR3 antagonist in inhibiting the progression of LPS-induced inflammation, osteoclastic activity, and bone resorption on a murine model. MATERIALS AND METHODS Thirty, 7-week-old C57BL/6 J male mice were used. Inflammatory bone loss was induced by Porphyromonas gingivalis-lipopolysaccharide (P.g.-LPS) injections between the first and second maxillary molars, bilaterally, twice a week for 6 weeks (n = 20). AMG-487 NP were incorporated into a liposome carrier and locally delivered on sites where P.g.-LPS was injected. Control mice (n = 10) were injected with vehicle only. Experimental groups included (1) control, (2) LPS, and (3) LPS + NP. At the end of 1 and 6 weeks, mice were euthanized, maxillae harvested, fixed, and stored for further analysis. RESULTS Volumetric bone loss analysis revealed, at 1 week, an increase in bone loss in the LPS group (47.9%) compared to control (27.4%) and LPS + NP (27.8%) groups. H&E staining demonstrated reduced inflammatory infiltrate in the LPS + NP group compared to LPS group. At 6 weeks, volumetric bone loss increased in all groups; however, treatment with the CXCR3 antagonist (LPS + NP) significantly reduced bone loss compared to the LPS group. CXCR3 antagonist treatment significantly reduced osteoclast numbers when compared to LPS group at 1 and 6 weeks. CONCLUSIONS This study showed that local delivery of a CXCR antagonist, via nanoparticles, in a bone resorption model, induced by LPS injection, was effective in reducing inflammation, osteoclast numbers, and bone loss. CLINICAL RELEVANCE CXCR3 blockade can be regarded as a novel target for therapeutic intervention of bone loss. It can be a safe and convenient method for periodontitis treatment or prevention applicable in clinical practice.

Abstract
Objectives In this study, we aimed to evaluate the association between grape seed proanthocyanidin extract (GSPE) and rheumatoid arthritis-fibroblast-like synoviocytes (RA-FLSs) and to investigate whether GSPE induces cell death in RA-FLSs. Materials and methods The FLSs were isolated from RA synovial tissues. Cell viability and cell cycle staging were analyzed using a hemocytometer and flow cytometry. Caspase 3 and poly (ADP-ribose) polymerase (PARP) proteins were analyzed using Western blotting with z-VAD-fmk. Protein LC3 and polyubiquitin-binding protein p62 that were degraded by autophagy were evaluated using Western blotting with 3-methyladenine and chloroquine. Reactive oxygen species (ROS) were also evaluated. Results When RA-FLSs were treated with GSPE, cell viability decreased, the number of cells in sub-G1 and G2/M phases increased, and the expression of pro-PARP and pro-caspase 3 proteins decreased in a concentration-dependent manner. This result was offset, when the cells were co-treated with the pan-caspase inhibitor z-VAD-fmk. The reduced cell viability, increased expression of LC3-II protein, and reduced expression of p62 protein with GSPE treatment were offset, when RA-FLSs were co-treated with GSPE and autophagy inhibitors 3-methyladenine and chloroquine. The level of ROS in RA-FLSs treated with GSPE was significantly lower than treatment with N-acetyl-cysteine, a ROS inhibitor. Conclusion Our study results show that GSPE induces apoptotic and autophagic cell death and inhibites reactive oxygen species in RA-FLSs.

Abstract
Lyme disease is caused by Borrelia burgdorferi, and the pathogenesis of the disease is complex with both bacterial and host factors contributing to inflammatory responses. Lyme disease affects different organs including joints and results in arthritis. Immune responses stimulated by B. burgdorferi through toll-like receptors cause infiltration of leukocytes, which produce inflammatory cytokines and facilitate spirochete clearance. However, arthritic manifestations and chronic fatigue syndrome-like symptoms persist long after completion of antibiotic treatment regimens in a significant number of patients. To counter the effects of inflammation, treatment by non-steroidal anti-inflammatory drugs, hydroxychloroquine, or synovectomy to eradicate inflammatory arthritis in the involved joint could be employed; however, they often have long-term consequences. Acupuncture has been used for a long time in Asian medicine to diminish pain during various ailments, but the effects and its mechanism are just beginning to be explored. Control of inflammation by neuronal stimulation has been exploited as a systemic therapeutic intervention to arrest inflammatory processes. Our objective was to determine whether activation of the sciatic-vagal network by electroacupuncture on ST36 acupoint, which is used to control systemic inflammation in experimental models of infectious disorders such as endotoxemia, can also alleviate Lyme arthritis symptoms in mice. This aim was further strengthened by the reports that sciatic-vagal neuronal network stimulation can lead to dopamine production in the adrenal medulla and moderate the production of inflammatory factors. We first assessed whether electroacupuncture affects spirochete colonization to attenuate Lyme arthritis. Interestingly, bioluminescent B. burgdorferi burden detected by live imaging and qPCR were similar in electroacupuncture- and mock-treated mice, while electroacupuncture induced a lasting anti-inflammatory effect on mice. Despite the discontinuation of treatment at 2 weeks, the simultaneous decrease in neutrophils in the joints and inflammatory cytokine levels throughout the body at 4 weeks suggests a systemic and persistent effect of electroacupuncture that attenuates Lyme arthritis. Our results suggest that electroacupuncture-mediated anti-inflammatory responses could offer promising healthcare benefits in patients suffering from long-term Lyme disease manifestations.

Abstract
Rheumatoid arthritis (RA) is an inflammatory disease that seriously affects human health worldwide. Meanwhile, inflammation in RAW264.7 cells could lead to the progression of RA. Alkannin (ALK) is derived from Alkanna tinctoria and is known to exert anti-tumor effects. However, the function of ALK in inflammation of RAW264.7 cells remains unclear. Thus, this research sought to investigate the detailed function of ALK in inflammatory responses of RAW264.7 cells. To induce an inflammatory response, RAW264.7 cells were exposed to lipopolysaccharide (LPS). MTT assay was applied to examine cell viability. Enzyme-linked immunosorbent assay (ELISA) was used to assess the levels of inflammatory cytokines. Furthermore, the mechanism underlying ALK function in inflammatory responses was investigated using RT-qPCR and western blotting. The data revealed that LPS significantly increased the expression of cyclooxygenase 2 (COX-2), Interleukin (IL)-1β, inducible nitric oxide synthase (iNOS), tumor necrosis factor-α (TNF-α), and IL-6, whereas ALK reversed this effect. ALK also restored LPS-induced nuclear factor kappa-B (NF-κB) activation by inhibiting the downregulation of p-inhibitor kappa B alpha (IκBα). LPS elevated p-extracellular regulated protein kinases 1/2 (ERK1/2), phosphorylated p38 (p-p38), and phosphorylated -c-Jun N-terminal kinase (p-JNK) levels, which were markedly decreased in the presence of ALK. In summary, Alkannin attenuated LPS-induced inflammation by inhibiting NF-κB and MAPK signaling. Thus, our research might provide a new theoretical basis for exploring new strategies against RA.

Abstract
Aim: Acute Lung Injury (ALI) is an acute hypoxic respiratory insufficiency caused by various traumatic factors, manifested as progressive hypoxemia and respiratory distress, and lung imaging shows a heterogeneous osmotic outbreak. Isorhamnetin (ISO) is a flavonoid compound isolated and purified from medicinal plants, such as Hippophae rhamnoides L. and Ginkgo, and has multiple pharmacological functions, such as anti-tumor, anti-myocardial hypoxia, and cardiovascular protection. Our previous study has shown that ISO could attenuate lipopolysaccharide (LPS)-induced acute lung injury in mice, but its mechanism is not clear.Methods: In this study, we used LPS-induced mouse and cell models to research the mechanism of ISO alleviating acute lung injury.Results: The results showed that ISO could attenuate the injury of type II alveolar epithelial cells by inhibiting the TLR4/NF-κB pathway. Further studies showed that ISO could inhibit the activation of mTOR signal in vivo and in vitro and promote autophagy in alveolar epithelial cells to reduce lung injury caused by LPS. In addition, ISO could inhibit LPS-induced epithelial cell apoptosis.Conclusion: Overall, ISO could suppress injury and apoptosis of epithelial cells and activate autophagy to protect epithelial cells via inhibiting mTOR signal and attenuating LPS-induced acute lung injury in mice.

Anti-proliferation and anti-inflammation effects of corilagin in rheumatoid arthritis by downregulating NF-κB and MAPK signaling pathways. JOURNAL OF ETHNOPHARMACOLOGY 2022; 284:114791. [PMID: 34737112 DOI: 10.1016/j.jep.2021.114791] [Citation(s) in RCA: 18] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/12/2021] [Revised: 10/19/2021] [Accepted: 10/27/2021] [Indexed: 06/13/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The dried aboveground part of Geranium Wilfordii Maxim. (G. Wilfordii) is a traditional Chinese herbal medicine named lao-guan-cao. It has long been used for dispelling wind-dampness, unblocking meridians, and stopping diarrhea and dysentery. Previous investigations have revealed that 50% ethanolic extract of G. Wilfordii has anti-inflammatory and anti-proliferation activities on TNF-α induced murine fibrosarcoma L929 cells. Corilagin (COR) is a main compound in G. Wilfordii with the content up to 1.69 mg/g. Pharmacology study showed that COR has anti-inflammatory, anti-tumor, anti-microorganism, anti-oxidant, and hepatoprotective effects. However, there is no any investigation on its anti-proliferation and anti-inflammation effects in rheumatoid arthritis (RA). AIM OF THE STUDY The present study aimed to evaluate the potential pharmacological mechanisms of anti-proliferation and anti-inflammation effects of COR in RA. MATERIALS AND METHODS In vitro, MH7A cells model induced by IL-1β was used. The anti-proliferation activity of COR was assessed by Cell Counting Kit-8 (CCK-8) assay, and the anti-migration and anti-invasion activity of COR was determined by wound healing assay and transwell assay, respectively. Furthermore, apoptosis assay by flow cytometer was used to measure the pro-apoptotic effect of COR. The mRNA expressions of Bax, Bcl-2, IL-6, IL-8, MMP-1, MMP-2, MMP-3, MMP-9, COX-2, and iNOS were measured by qRT-PCR, and related protein were further verified by ELISA kits or Western blot. Moreover, protein levels associated with NF-κB and MAPK signaling pathways of p65, P-p65, IκBα, P-IκBα, ERK1/2, P-ERK1/2, JNK, P-JNK1/2/3, p38, and P-p38 were determined by Western blot. The nuclear translocation of NF-κB-p65 was detected by immunofluorescent staining. In vivo, adjuvant-induced arthritis (AIA) rat model was used, and the body weight, paw swelling, and arthritis score during the entire period were measured. Histopathological analysis of joints of synovial tissues was also determined. The expression of pro-inflammatory cytokines in serum including IL-6, TNF-α, IL-1β, and IL-17 were measured. RESULTS The in vitro results showed that COR could dose-dependently inhibit the proliferation, migration, and invasion of IL-1β-induced MH7A cells, as well as promote its apoptosis. Moreover, it also suppressed the over-expression of Bcl-2, IL-6, IL-8, MMP-1, MMP-2, MMP-3, MMP-9, COX-2, and iNOS while up-regulated the level of Bax. Besides, the ratios of P-p65/p65, P-IκBα/IκBα, P-ERK/ERK, P-JNK/JNK, and P-p38/p38 were decreased, and the nuclear translocation of p65 induced by IL-1β was blocked by COR. In vivo results indicated that COR significantly reduced the paw swelling and arthritis score in AIA rats, and inhibited synovial tissue hyperplasia and erosion, as well as inflammatory cells infiltration. It also decreased the serum pro-inflammatory cytokines (IL-6, TNF-α, IL-1β, and IL-17) production. CONCLUSION These results revealed that COR exerted anti-rheumatoid arthritis effect, and its underlying mechanisms may be related to inhibiting the proliferation, migration, and invasion of synovial fibroblasts, enhancing cell apoptosis, and suppressing inflammatory responses via downregulating NF-κB and MAPK signaling pathways.

BACKGROUND Venetoclax, a selective B-cell lymphoma-2 (BCL2) inhibitor, has a potential therapeutic effect when combined with demethylating agents in the first-line setting of unfit elderly patients with acute myeloid leukaemia (AML); however, efficacy is still limited in refractory/recurrent AML. Therefore, exploration of a suitable novel treatment scheme is urgently needed.However, combining venetoclax with NK cell-based immunotherapy has not been studied. METHODS The cytotoxicity of NK cell combined with venetoclax was assessed in vitro using flow cytometry. Venetoclax-induced natural killer group 2 member D (NKG2D) ligand (NKG2DL) expression was detected by flow cytometry and western blotting. Mechanisms underlying venetoclax-induced NKG2DL expression were found by GSE127200 analysis and investigated using real-time PCR (Q-PCR) and western blotting. RESULTS Flow cytometric analysis showed that combining venetoclax with NK cells produced synergistic anti-leukaemia effects similar to those of venetoclax + azacitidine. Venetoclax could render AML cell lines and primary AML cells sensitive to NK cell killing by promoting NK cell degranulation, NK-AML cell recognition and NK cell secretion of interferon (IFN)-γ and granzyme B. The synergistic effect resulted from venetoclax-induced NKG2DL upregulation in AML cells and could be undermined by blocking NKG2D on NK cells. This finding suggests that venetoclax enhances NK cell killing activity by activating the NKG2D/NKG2DL ligand-receptor pathway. Furthermore, the nuclear factor-kappa-B (NFKB) signalling pathway was involved in venetoclax-induced NKG2DL upregulation. CONCLUSIONS Collectively, our data confirm that venetoclax combined with NK cells induces synergistic AML cell cytolysis and preliminarily revealed that venetoclax could selectively induce NKG2DLs on AML cells via NFKB signalling pathway.

Biological Anti-TNF- α Therapy and Markers of Oxidative and Carbonyl Stress in Patients with Rheumatoid Arthritis. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2022; 2021:5575479. [PMID: 34976302 PMCID: PMC8716244 DOI: 10.1155/2021/5575479] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/26/2021] [Revised: 11/23/2021] [Accepted: 11/30/2021] [Indexed: 12/04/2022]
Abstract
Rheumatoid arthritis (RA) as a chronic inflammatory disease is associated with oxidative stress. Drugs targeting tumor necrosis factor-alpha (TNF-α) ameliorate inflammation and symptoms of RA in most patients. Whether markers of oxidative stress can be used for monitoring of treatment effects is unknown. The aim of our study was to analyze the effects of anti-TNF-α treatment on oxidative stress in plasma and saliva of patients with RA. Samples were collected from 26 patients with RA at baseline as well as 3 and 6 months after starting the anti-TNF-α treatment. Thiobarbituric acid-reacting substances (TBARS), advanced oxidation protein products (AOPP), advanced glycation end products (AGEs), and fructosamine were quantified using spectrophotometry and spectrofluorometry in plasma. TBARS were measured also in saliva. The disease activity score (DAS28) was used to assess the clinical status of patients. No significant dynamic changes were found except plasma TBARS that decreased continuously. At 6 months after starting the treatment, plasma TBARS were lower by 39% in comparison to baseline (p = 0.006). Salivary concentrations of TBARS did not reflect the dynamics in plasma. Although a trend was observed (r = 0.33), a significant correlation between plasma TBARS and DAS28 was not found. Our results indicate that anti-TNF-α treatment decreases plasma TBARS as a marker of lipid peroxidation. However, the lack of a significant correlation with DAS28 suggests that it cannot be used for monitoring of treatment. Other markers of oxidative stress and antioxidant capacity with lower biological variability should be tested in future studies.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Herba taxilli (HT, Sangjisheng in Chinese), which is composed of the dried stems and leaves of Taxillus chinensis (DC.) Danser, has been commonly used to treat inflammation and arthritis in traditional Chinese medicine (TCM). Quercetin (Que) is a major active flavonoid component isolated from HT and is one of the quality control indexes of HT. In the clinical practice of TCM, formulas containing HT are commonly used to treat rheumatoid arthritis (RA). Recent studies have shown that Que exerts antiarthritic effects. However, the mechanism by which Que treatment affects RA is not fully understood. AIM OF THE STUDY This study aimed to explore the antiarthritic activity of Que in a collagen-induced arthritis (CIA) mouse model and investigate the underlying mechanisms. MATERIALS AND METHODS The antiarthritic activity of Que was evaluated in a CIA mouse model by determining the paw clinical arthritis scores and left ankle thicknesses and by conducting micro-PET imaging and histopathological analysis of ankle joint tissues. The proinflammatory cytokine (IL-6, TNF-α, IL-1β, IL-8, IL-13, IL-17) levels in the serum and ankle joint tissues were measured by ELISA. Mitochondrial oxidative stress was assessed by biochemical methods. Mitochondrial biogenesis was analysed by RT-qPCR. The protein levels of silent information regulator 1 (SIRT1), peroxisome proliferator-activated receptor γ coactivator-1α (PGC-1α), nuclear respiratory factor 1 (NRF1), mitochondrial transcription factor A (TFAM), high-mobility group box 1 (HMGB1), Toll-like receptor 4 (TLR4), p38, phospho-p38, extracellular signal-regulated kinases (ERK)-1/2, phospho-ERK1/2, p65, and phospho-p65 in ankle joint tissues were detected by Western blot analysis. A total of 30 RA patients were recruited to investigate the relationship between the disease activity score (DAS28) and the SIRT1, PGC-1α, NRF1, and HMGB1 plasma levels. RESULTS Que treatment decreased the clinical score and left ankle thickness of CIA mice, attenuated the synovial inflammation and hyperplasia and bone/cartilage destruction in ankle joints, and decreased the secretion of IL-6, TNF-α, IL-1β, IL-8, IL-13, and IL-17. Mechanistically, Que treatment improved impaired mitochondrial biogenesis and mitochondrial function by regulating the SIRT1/PGC-1α/NRF1/TFAM pathway and inhibited inflammation via the HMGB1/TLR4/p38/ERK1/2/NF-κB p65 pathway. Notably, epidemiological data revealed correlations between abnormal circulating levels of SIRT1, PGC-1α, NRF1, HMGB1 and RA disease activity in patients. CONCLUSIONS Our data suggested a potential role of Que as a dietary therapeutic drug for RA treatment that may act through SIRT1 to target mitochondrial biogenesis. Additionally, the role of impaired mitochondrial biogenesis in RA was evaluated.

Abstract
BACKGROUND The current outbreak of coronavirus disease 2019 (COVID-19) has rapidly spread throughout the world. During treatment, we found that the majority of patients had a decrease in hemoglobin (Hb). Interferon-α2b (IFN-α2b) was the primary suspected drug that was related to Hb reduction. Thus, the study aimed to investigate whether IFN-α2b could induce Hb reduction in severe patients with COVID-19 and its potential mechanism. MATERIAL AND METHODS A total of 50 patients who were admitted to the First Affiliated Hospital of Harbin Medical University with severe COVID-19 infection were enrolled from February 12th to 24th, 2020. The demographics, baseline characteristics, clinical data, and therapeutic regimen were collected retrospectively. The patients were divided into two groups according to the declined use of IFN-α2b on day 14. The Hb levels on admission, day 7, day14, and day 21 were collected and analyzed. The primary endpoint was the level of Hb on day 21. RESULTS A total of 31 patients in the IFN-stop group and 19 patients in the non-IFN-stop group were reviewed. The age, gender, comorbidities, clinical symptoms, nutritional status, disease severity, complications, and other factors of the patients were compared, no difference was found between the IFN-stop group and the non-IFN-stop group. The Hb levels of all patients significantly decreased on day 7 compared with that on admission (p < .0001). In the IFN-stop group, the Hb level was increased in 7 days after IFN-α2b was stopped (p = .0008), whereas no difference was found between day 14 and day 21 in the non-IFN-stop group (p = .3152). CONCLUSIONS IFN-α2b was associated with Hb reduction in the treatment of severe patients of COVID-19. Clinicians should be aware of the high incidence of Hb reduction for patients treated by IFN-α2b.

Abstract
Fibroblast-like synoviocytes (FLS) are the critical effector cells primarily involved in rheumatoid arthritis (RA) disease pathogenesis. Interleukin (IL)-6, a proinflammatory cytokine most abundantly expressed in the rheumatoid synovium, promotes Janus kinase (JAK)/signal transducer and transcriptional activator (STAT) signaling cascade activation in RA-FLS, thus leading to its aggressive phenotype, invasiveness, and joint destruction. Momelotinib (CYT387) is a selective small-molecule inhibitor of JAK1/2 and is clinically approved to treat myelofibrosis. However, the therapeutic efficacy of CYT387 in FLS mediated RA pathogenesis is less known. In the present study, we investigated the modulatory effect of CYT387 on IL6/JAK/STAT signaling cascade in FLS induced RA pathogenesis. CYT387 treatment inhibited IL-6 induced high proliferative and migratory potential of FLS cells isolated from adjuvant-induced arthritic (AA) rats. CYT387 reduced the expression of PRMT5, survivin, and HIF-1α mediated by IL-6/sIL-6R in AA-FLS in a dose-dependent manner. The IL-6/sIL-6R induced expression of angiogenic factors such as VEGF and PIGF in AA-FLS cells was found downregulated by CYT387 treatment. Importantly, CYT387 significantly reduced IL-6/sIL-6R dependent activation of JAK1 and STAT3 and increased SOCS3 expression in AA-FLS cells. Next, the S3I-201 mediated blockade of STAT3 activation supported the inhibitory effect of CYT387 on IL-6/JAK1/STAT3 signaling cascade in AA-FLS. Overall, this study proves that CYT387 inhibits proliferation, migration, and pathogenic disease potential of FLS isolated from adjuvant-induced arthritic (AA) rats via targeting IL-6/JAK1/STAT3 signaling cascade.

Abstract
Objectives Rheumatoid arthritis (RA) is a disabling disease with a high incidence that is regularly accompanied by cardiovascular complications. Several studies have suggested that renin–angiotensin–aldosterone system (RAAS) is closely associated with RA. The aim of this study was to investigate the mechanisms underlying Angiotensin-(1–7) [Ang-(1–7)] and its Mas receptor agonist (AVE0991) on joint inflammation and cardiac complications in a collagen-induced arthritis (CIA) model. Methods Collagen type II was injected into DBA/1 mice to construct an arthritis model. CIA mice were treated with Ang-(1–7) (2.0 mg/kg intraperitoneally) and AVE0991 (3.0 mg/kg intraperitoneally). The serum levels of inflammatory cytokines [tumor necrosis factor-alpha (TNF-α), interleukin (IL)-1 β, IL-6, and C-reactive protein (CRP)] were determined by ELISA. The mitogen-activated protein kinase (MAPK) and nuclear factor-kappaB (NF-κB) signaling pathways in joint tissues and the transforming growth factor (TGF)-β/Smad pathway and levels of α-Smooth muscle action (SMA) and β-myosin heavy chain (MHC) protein expression in cardiac tissues were assessed by western blots. The levels of TGF-β/Smad pathway, α-SMA, and β-MHC RNA in cardiac tissues were analyzed by real time-PCR. The levels of receptor activator of nuclear factor kappa ligand (RANKL) and promoting matrix metalloproteinase (MMP)-3 expression in the ankle joints were detected by immunohistochemistry and real time-PCR. Results Ang-(1–7) and AVE0991 reduced the levels of inflammatory cytokines and inhibited the MAPKs and NF-κB signaling pathways in ankle joint tissues, reduced RANKL and MMP3 expression, and ameliorated local joint inflammation and bone destruction compared with the control group. In addition, Ang-(1–7) and AVE0991 attenuated the TGF-β/Smad signaling pathway, reduced the levels of α-SMA and β-MHC expression, and diminished inflammatory cell infiltration into the myocardial interstitium and myocardial interstitial fibrosis in the hearts of CIA mice. Conclusions Ang-(1–7) alleviated joint damage caused by inflammation likely through the attenuation of NF-κB and MAPK pathways and ameliorated inflammation-induced cardiac fibrosis and activation of the TGF-β/Smad pathway. Moreover, Ang-(1–7) was likely mediated through the Mas receptor. This study provides theoretical evidence for exploring novel clinical therapeutic approaches for RA and its cardiac complications.
