Objective: To investigate the expression pattern of transforming growth factor-β-inducible gene-h3 (βig-h3) within rheumatoid synovial tissue and the regulation of βig-h3 synthesis in fibroblast-like synoviocyte (FLS). Methods: Synovial tissues obtained from patients with rheumatoid arthritis and osteoarthritis were obtained during joint replacement surgery. βig-h3 expression was evaluated with immunohistochemical stain. FLS was isolated from synovial tissues and stimulated with cytokines including TGF-β, TNF-α, IL-1β, IFN-γ, IL-6, IL-4, and IL-10. βig-h3 synthesis was measured using semiquantitative RT-PCR, ELISA, immunofluorescence stain, and flow cytometry. Results: Expression of βig-h3 was diffuse and abundant in both lining and sublining layers of rheumatoid synovium, which was more prominent than those of osteoarthritis. Production of βig-h3 in FLS was regulated by TGF-β1 in a dose-dependent manner and was highest at 5 ng/mL of TGF-β1. TNF-α and IL-1β upregulated the production of βig-h3 from FLS synergistically with TGF-β1 but other cytokines such as IL-4, IL-6, IL-10 did not affect. βig-h3 synthesis was efficiently inhibited by dexamethasone at higher dose (100 nM) but not by cyclosporine-A. Conclusion: Production of βig-h3, which is highly upregulated in rheumatoid synovitis, is differentially regulated by inflammatory cytokines.

A hot-water extract of <i>Sanguisorba officinalis</i> ameliorates endotoxin-induced septic shock by inhibiting inflammasome activation : HSO attenuates inflammasome activation

Seo, Dong-Won,Cho, Yong-Il,Gu, Suna,Kim, Da-Hee,Yi, Young-Joo,Lee, Sang-Myeong Center for Academic Publications Japan 2018 Microbiology and immunology Vol.62 No.1

<P>The inflammasome is a multiprotein signaling complex that mediates inflammatory innate immune responses through caspase 1 activation and subsequent IL-1 secretion. However, because its aberrant activation often leads to inflammatory diseases, targeting the inflammasome holds promise for the treatment of inflammation-related diseases. In this study, it was found that a hot-water extract of Sanguisorba officinalis (HSO) suppresses inflammasome activation triggered by adenosine 5-triphosphate, nigericin, microbial pathogens, and double stranded DNA in bone marrow-derived macrophages. HSO was found to significantly suppress IL-1 production in a dose-dependent manner; this effect correlated well with small amounts of caspase 1 and little ASC pyroptosome formation in HSO-treated cells. The anti-inflammatory activity of HSO was further confirmed in a mouse model of endotoxin-induced septic shock. Oral administration of HSO reduced IL-1 titers in the serum and peritoneal cavity, increasing the survival rate. Taken together, our results suggest that HSO is an inhibits inflammasome activation through nucleotide-binding domain and leucine-rich repeat pyrin domain 3, nucleotide-binding domain and leucine-rich repeat caspase recruitment domain 4 and absent in melanoma 2 pathways, and may be useful for treatment of inflammasome-mediated diseases.</P>

Objectives: This study was performed to investigate the effects of Gagamsosokmyeong-tang(Jiajianxiaoxuming-tang) on the monosodium iodoacetate(MIA) induced early stage osteoarthritis in rats. Methods: Osteoarthritis was induced by injection of MIA(0.25 mg) into knee joints of rats. Osteoarthritic rats were divided into control(n=8) and treated(n=8) group respectively. Control group was taken distilled water and treated group was taken extracts of Gagamsosokmyeong-tang(Jiajianxiaoxuming-tang) by orally for 20 days. Body weight was measured at 0, 5, 10, 15, 20 days after MIA injection. At the end of experiment, gross and histopathological examination on the articular cartilages of the knee joints were performed. Proteoglycan(PG) content of articular cartilages were analysed by safranine O staining method. The content of tumor necrosis factor-α(TNF-α), interleukin-1β(IL-1β) in synovial fluids were analysed by enzyme-linked immunosorbent assay(ELISA) method. And also cyclooxygenase-2(COX-2), matrix metalloproteinase 3(MMP-3), inducible nitric oxide synthase(iNOS), calpain immunohistochemical examination on the knee joints were performed. Results: PG content in articular cartilages of the treated group was significantly increased compared with control group. Histopathological osteoarthritic score of the treated group was significantly decreased compared with control group. TNF-α content in synovial fluids, expression of iNOS and calpain in synovial membrane of the treated group were significantly decreased compared with control group. But body weight, IL-1β content in synovial fluids, expression of iNOS and MMP-3 of the treated group were not significantly changed compared with control group. Conclusions: On the basis of these results, we conclude that Gagamsosokmyeong-tang(Jiajianxiaoxuming-tang) has anti-arthritic effects on the MIA induced early stage osteoarthritis in rats.

Oh, Keunhee,Seo, Myung Won,Kim, In Gyu,Hwang, Young-Il,Lee, Hee-Yoon,Lee, Dong-Sup The Korean Association of Immunobiologists 2013 Immune Network Vol.13 No.6

Although pathogenesis of human rheumatoid arthritis (RA) remains unclear, arthritogenic T cells and downstream signaling mediators have been shown to play critical roles. An increasing numbers of therapeutic options have been added for the effective control of RA. Nevertheless, there is still a category of patients that fails treatment and suffers from progressive disease. The recently developed immunosuppressant CP-690550, a small molecule JAK kinase inhibitor, has been implicated as an important candidate treatment modality for autoimmune arthritis. In this study, we evaluated the therapeutic effect of CP-690550 on established arthritis using an SKG arthritis model, a pathophysiologically relevant animal model for human RA. CP-690550 treatment revealed remarkable long-term suppressive effects on SKG arthritis when administered to the well-advanced disease (clinical score 3.5~4.0). The treatment effect lasted at least 3 more weeks after cessation of drug infusion, and suppression of disease was correlated with the reduced pro-inflammatory cytokines, including IL-17, IFN-${\gamma}$, and IL-6 and increased level of immunoregulatory IL-10.

Background & Objective: Articular cartilage is a potential target for drugs designed to inhibit the activity of matrix metalloproteinases (MMPs) to stop or slow the destruction of the proteoglycan and collagen in the cartilage extracellular matrix. The purpose of this study was to investigate the effects of Aralia cordata Thunb. in inhibiting the release of glycosaminoglycan (GAG), the degradation of collagen, and MMP activity in rabbit articular cartilage explants. Methods : The cartilage-protective effects of Aralia cordata Thunb. were evaluated by using glycosaminoglycan degradation assay, collagen degradation assay, colorimetric analysis of MMP activity, measurement of lactate dehydrogenase activity and histological analysis in rabbit cartilage explants culture. Results : Interleukin-la (IL-1a) rapidly induced GAG, but collagen was much less readily released from cartilage explants. Aralia cordata Thunb. significantly inhibited GAG and collagen release in a concentration-dependent manner. Aralia cordata Thunb. dose-dependently inhibited MMP-3 and MMP-13 expression and activities from IL-1a-treated cartilage explants cultures when tested at concentrations ranging from 0.02 to 0.2 mg/ml. Aralia cordata Thunb. had no harmful effect on chondrocytes viability or cartilage morphology in cartilage explants. Histological analysis indicated that Aralia cordata Thunb. reduced the degradation of the cartilage matrix compared with that of IL -1a-treated cartilage explants.

Background/Aims: This study was designed to evaluated the effects of electroacupuncture on the sphincter of Oddi (SO) motility in humans and to correlate the manometric findings with plasma cholecystokinin (CCK) levels. Methods: Eleven patients (M: F= 5: 6) who had various kinds of biliary disorders were enrolled. SO motility was monitored with a conventional low-compliant continuously perfused technique using ERCP (n=9) or percutaneous transhepatic cholangioscope (n=2). After baseline monitoring for phasic wave contractions of SO, electroacupuncture was applied at a specific acupoint, GB 34, in these 11 patients. A nonspecific acupoint 5 cm away from GB 34 was selected as a control. Manometric parameters of SO were also checked in 6 subjects during stimulation of the control acupoint. CCK plasma levels were measured during the time course of electroacupuncture stimulation. Result: All the manometric parameters including the basal pressure of SO, amplitude, frequency and duration of phasic wave contraction of SO were significantly decreased (p< 0.05) during electroacupuncture stimulation. The inhibition of SO contractility was accompanied by increased CCK plasma levels. After removal of electroacupuncture stimulation, restoration of amplitude and duration to basal condition were noted. A tendency towards the return of SO contractility was also observed in basal pressure and frequency. Stimulation of the control acupoint, however, did not affect the SO contractility and plasma CCK levels. Conclusions: Electroacupuncture stimulation of acupoint GB 34 showed reversible inhibition of SO contraction in humans. We speculate that the response of SO to electroacupuncture stimulation may be mediated by some neurohormonal mechanisms including CCK release.

Background: Keratinocytes are the major cells inepidermis, providing barrier components such as cornified cells through the sophisticated differentiation process. In addition, keratinocytes exerts their role as the defense cells via activation of innate immunity. It has been knownthat pathogen-associated molecular patterns (PAMPs) including double-strand RNA and nucleotides can provoke inflammatory reaction in keratinocytes. Objectives: The aim of this study is to evaluate the effect of Ampelopsis japonica Makino extract (AE) on PAMPs-induced inflammatory reaction of keratinocytes. Methods: The effects of AE were determined using poly(I:C)-induced inflammation and imiquimod-induced psoriasiform dermatitis models. Results: In cultured keratinocytes, AE significantly inhibited poly(I:C)-induced expression of inflammatory cytokines, such as IL-1モ, IL-6, IL-8 and TNF-メ. AE significantly inhibited poly(I:C)-induced release of caspase-1 active form (p20), and down-regulated NF-リB signaling pathway. In imiquimod-induced psoriasiform dermatitis model, topical application of AE resulted in significant reduction of epidermal hyperplasia. Conclusion: These results suggest that AE may be a potential candidate for the treatment of skin inflammation.
