        IL-15에 의한 류마티스관절염 환자 활막 섬유모세포에서의 SDF-1 유도

        박영은 ( Young Eun Park ),김성일 ( Sung Il Kim ),박성후 ( Seong Hu Park ),백승훈 ( Seung Hoon Baek ),오혜좌 ( Hye Jwa Oh ),허양미 ( Yang Mi Heo ),조미라 ( Mi La Cho ) 대한류마티스학회 2010 대한류마티스학회지 Vol.17 No.3

        Objective: Interleukin-15 (IL-15) recruits and activates synovial T cells, and IL-15 plays an important role in amplifying and perpetuating inflammation in the pathogenesis of rheumatoid arthritis (RA). Stromal cell-derived factor-1 (SDF-1) is a potent chemoattractant for memory T cells in the inflamed RA synovium. This study investigated the effect of IL-15 on SDF-1 production in RA fibroblast-like synoviocytes (FLS). Methods: The expressions of IL-15 and SDF-1 were determined from the synovium of patients with RA and osteoarthritis (OA) by performing immunohistochemistry. The expressions of SDF-1 was measured from the RA FLS that were cultured with IL-15 and IL-17 by real-time RT-PCR and ELISA. The SDF-1 expression was also measured, via ELISA, from the RA FLS stimulated by IL-15 together with the inhibitors of such intracellular signal molecules as phosphatidylinositol 3-kinase (PI 3-kinase, LY294002), STAT3 (AG490), MAP Kinase (PD98059), NF-κB (parthenolide) and activator protein 1 (AP-1, curcumin). Results: IL-15 and SDF-1 were mainly expressed in the RA synovium compared to that of the OA synovium. IL-15 increased the SDF-1 expressions and it, and had an additive effect with IL-17 on the SDF-1 expressions in the cultured RA FLS. The IL-15 induced increase of the SDF-1 expression in the cultured RA FLS was blocked by the inhibitors of PI 3-kinase, NF-κB and AP-1. Conclusion: The SDF-1 expression was increased in the RA synovium and it was up-regulated by IL-15 in the RA FLS through the PI 3-kinase, NF-κB, and AP-1 pathways. These results imply that the IL-15 induced increase of the SDF-1 expressions may be involved in the immunopathogenesis of RA.

      • The enhanced IL-l8 production by UVB irradiation requires ROI and AP-1 signaling in human keratinocyte cell line (HaCaT)

        Cho, Daeho,Kang, Jae Seung,Park, Jong Hoon,Kim, Young-In,Hahm, Eunsil,Lee, Junechul,Yang, Yoolhee,Jeon, Junho,Song, HyunKeun,Park, Hyunjeong,Kim, Taesung,Pang, Saic,Kim, Chul-Woo,Hwang, Young Il,Lee, 전남대학교 약품개발연구소 2002 약품개발연구지 Vol.11 No.-

        Based on our recent observation that enhanced IL-18 expression positively correlates with malignant skin tumors, such as SCC and melanoma, we examined the possible role of UVB, known to be associated with skin cancer development, in the enhancement of IL-18 production using primary human epidermal keratinocytes and human cell line HaCaT. After cells were exposed to UVB irradiation in vitro, IL-18 production was examined by Northern blot analysis and ELISA, and it was found that IL-18 production is enhanced by UVB irradiation in a dose- and time-dependent manner. In addition, we confirmed that it is functionally active form of IL-18 using the inhibitor of caspase-1. The effect of UVB irradiation was blocked by antioxidant, N-acetyl-ι-cysteine (NAC), which suggested the involvement of reactive oxygen intermediates (ROI) in the signal transduction of UVB irradiation-enhanced IL-18 synthesis. We also found that UVB irradiation increased AP-1 binding activity by using EMSA with AP-1-specific oligonucleotide. Furthermore, inhibitors of UVB-induced AP-1 activity, such as PD98059, blocked enhanced IL-18 production, indicating that AP-1 activation is required for UVB-induced IL-18 production. Taken together, our results suggest that UVB irradiation-enhanced IL-18 production is selectively mediated through the generation of ROI and the activation of AP-1.

        A novel role for bone-derived cells in ankylosing spondylitis: Focus on IL-23

        Jo, Sungsin,Koo, Bon San,Lee, Bitnara,Kwon, Eunji,Lee, Young Lim,Chung, Heekyoung,Sung, Il-Hoon,Park, Ye-Soo,Kim, Tae-Hwan Elsevier 2017 Biochemical and biophysical research communication Vol. No.

        <P><B>Abstract</B></P> <P>The main aim of this study are to explore the role of bone-derived cells (BdCs) in ankylosing spondylitis (AS) and determine the underlying molecular mechanisms of IL-23 production. Primary BdCs were isolated from diced bone of facet joints obtained during surgery from seven AS patients and seven disease control (Ct) patients. Osteoblastic activity of BdCs was assessed by measuring their alkaline phosphatase activity and by alizarin red staining. Osteoblast and endoplasmic reticulum (ER) stress-related genes were assessed by quantitative PCR, immunoblotting, immunofluorescence, and immunohistochemistry. In addition, expression of IL-23 in response to BIX (selective BIP inducer X)-induced ER stress was evaluated by qPCR and ELISA. Protein interaction and binding to IL-23 promoter were confirmed by Immunoprecipitation and Chromatin immunoprecipitation, respectively. Transcript levels of genes involved in osteoblast function, as well as of the ER stress marker were higher in the AS group than the Ct group, and elevated RUNX2, BiP and IL-23 expression were observed in the BdCs, serum, and bone biopsies from the AS group. BIX-induced ER stress stimulated osteoblastic activity and IL-23 secretion by upregulating RUNX2 expression. Furthermore, in AS BdCs, RUNX2 interacted with C/EBPβ to bind to IL-23 promoter and RUNX2 knockdown suppressed IL-23 secretion. These finding may provide a molecular mechanism involved in sustained ER stress in AS BdCs stimulates the activation of RUNX2 and C/EBPβ genes, leading to IL-23 production.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Bones and its-derived cells from patients with AS showed an increase in ER stress. </LI> <LI> IL-23 cytokine was significantly higher in AS patients than in healthy controls. </LI> <LI> Inducing ER stress in AS exhibited an increase of bone-related genes. </LI> <LI> Inducing ER stress in AS was accompanied with augmentation of IL-23 cytokine. </LI> <LI> ER stress-induced RUNX2 is involved in IL-23 secretion and bone-related genes. </LI> </UL> </P>

        Gene therapy of intracranial glioma using interleukin 12-secreting human umbilical cord blood-derived mesenchymal stem cells.

        Ryu, Chung Heon,Park, Sang-Hoon,Park, Soon A,Kim, Seong Muk,Lim, Jung Yeon,Jeong, Chang Hyun,Yoon, Wan-Soo,Oh, Won-il,Sung, Young Chul,Jeun, Sin-Soo Mary Ann Liebert 2011 Human gene therapy Vol.22 No.6

        <P>Clinical trials of gene therapy using a viral delivery system for glioma have been limited. Recently, gene therapy using stem cells as the vehicles for delivery of therapeutic agents has emerged as a new treatment strategy for malignant brain tumors. In this study, we used human umbilical cord blood-derived mesenchymal stem cells (UCB-MSCs) as delivery vehicles with glioma-targeting capabilities, and modified interleukin-12 (IL-12p40N220Q; IL-12M) as a novel therapeutic gene. We also engineered UCB-MSCs to secret IL-12M (UCB-MSC-IL12M) via tetrameric cell-permeable peptide (4HP4)-mediated adenoviral transduction. We confirmed the migratory capacity of UCB-MSC-IL12M toward GL26 mouse glioma cells by an in vitro migration assay and in vivo injection of UCB-MSC-IL12M into the ipsilateral hemisphere of implanted gliomas in C57BL/6 mice. In vivo efficacy experiments showed that intratumoral injection of UCB-MSC-IL12M significantly inhibited tumor growth and prolonged the survival of glioma-bearing mice compared with control mice. Antitumor effects were associated with increased local IL-12M levels, followed by interferon-γ secretion and T-cell infiltration in intracranial gliomas, as well as antiangiogenesis. Interestingly, tumor-free mice after UCB-MSC-IL12M treatment were resistant to ipsilateral and contralateral tumor rechallenge, which was closely associated with tumor-specific long-term T-cell immunity. Thus, our results provide the rationale for designing novel experimental protocols to induce long-term antitumor immunity against intracranial gliomas using UCB-MSCs as an effective delivery vehicle for therapeutic cytokines including IL-12M.</P>

        Triptolide suppresses interleukin-1beta-induced human beta-defensin-2 mRNA expression through inhibition of transcriptional activation of NF-kappaB in A549 cells.

        Jang, Byeong-Churl,Lim, Ki-Jo,Choi, In-Hak,Suh, Min-Ho,Park, Jong-Gu,Mun, Kyo-Chul,Bae, Jae-Hoon,Shin, Dong-Hoon,Suh, Seong-Il D.A. Spandidos 2007 INTERNATIONAL JOURNAL OF MOLECULAR MEDICINE Vol.19 No.5

        <P>The immunosuppressive effect of triptolide has been associated with suppression of T-cell activation. However, the immunosuppressive effects of triptolide on innate immunity in the epithelial barrier remain to be elucidated. Human beta-defensin (HBD)-2 is an inducible antimicrobial peptide and plays an important role in the innate immunity. We have previously demonstrated that IL-1beta induced HBD-2 mRNA expression in A549 cells through activation of nuclear factor-kappaB (NF-kappaB) transcriptional factor as well as p38 mitogen-activated protein kinase (MAPK), c-Jun N-terminal kinase (JNK), or phosphatidylinositol-3-kinase (PI3K). In this study, we investigated effects of triptolide on IL-1beta-induced HBD-2 mRNA expression in A549 cells. Triptolide inhibited IL-1beta-induced HBD-2 mRNA expression in a dose-dependent manner. Addition of triptolide did not suppress activation of p38 MAPK, JNK, or PI3K in response to IL-1beta. Triptolide inhibited IL-1beta-induced MAPK phosphatase-1 expression at the transcriptional level and resulted in sustained phosphorylation of JNK or p38 MAPK, explaining the little effect of triptolide on IL-1beta-induced phosphorylation of these kinases. Although triptolide partially suppressed IL-1beta-mediated degradation of IkappaB-alpha and nuclear translocation of p65 NF-kappaB, triptolide potently inhibited NF-kappaB promoter-driven luciferase activity in A549 cells. These results collectively suggest that the inhibitory effect of triptolide on IL-1beta-induced HBD-2 mRNA expression in A549 cells seems to be at least in part mediated through nuclear inhibition of NF-kappaB transcriptional activity, but not inhibition of p38 MAPK, JNK, or PI3K. This inhibition may explain the ability of triptolide to diminish innate immune response.</P>

      • 몇 가지 항균제가 시험관내에서 내독소와 TNF-α, IL-6 분비에 미치는 영향

        최정현,문건웅,김명훈,이동건,박윤희,김상일,김태연,유진홍,김양리,신완식,강문원 대한화학요법학회 1997 대한화학요법학회지 Vol.15 No.2

        To evaluate antibiotic-induced endotoxin release(AIER) and its correlation with some cytokines, we measured endotoxin level and tumor necrosis factor alpha(TNF-α) and interleukin6(IL-6) production in mononuclear cells in vitro after exposure of Pseudomonas aeruginosa to antibiotics belonging to different class with two extreme concentrations. The tested concetration of antibiotics were set up according to peak serum level. The low concetration of ceftazidirne and low concentration of imiperiem increased AIER, but high concentration of ceftazideme, high concentration of ciprofloxacin, high concentration of cefoperazone/sulbactam, high concentration of amikacin, and high concentration of meropenem reduced AIER.Interestingly, combined treatment of these antibiotics markedly reduced AIER, But the major cyotkines, TNF-α and IL-6 were not affect by type and concettration of antibiotics, combined treatment of antibiotics, and level of endotoxin released by antiboitics. In this study, we observed AIER was different according to type of antibiotics, concentration of antibiotics, and combination of antibiotics, But AIER had poor correlation with TNF-α and IL-6 in Pseudomonas aeruginosa. It suggests that cytokine release is not solely dependent to endotoxin, but more complex cascade is needed. More invesfigations, such as endotoxin induced cytokine mRNA expression, relationship with penicillin-binding proteins and endotoxin-neutralizing effect of antibiotic itself, must be performed.
