        Objective : The purpose of this study is to investigate the inflammatory-control effects of Cheonghyeol-antidote complex(Lonicera japonica Thunberg, Forsythia viridissima Lindley, and Taraxacum platycarpum H. Dahlstedt complex, CHA) in LPS-induced RAW264.7 cell and mouse inflammation models. Method : For in vitro and in vivo experiment, Indicators such as cell viability, mRNA expression level(iNOS, IL-6, IL-1β, COX-2, TNF-a), Inflammatory factor production(NO, IL-6, IL-1β, TNF-a), and protein phosphorylation level(ERK, JNK, p38) were analyzed. For in vivo experiment, Indicators such as mRNA expression level(iNOS, IL-6, IL-1β, COX-2, TNF-a), Inflammatory factor production(IL-6, IL-1β, TNF-a), protein phosphorylation level(ERK, JNK, p38) and immune cell(white blood cell, lymphocyte) were analyzed. Results : 1. In vitro experiment In cell viability of CHA, CHA showed cell viability below 90% at concentrations of 400 μg / ml or more. In mRNA expression level, IL-6 and IL-1β showed a significant decrease at all concentrations except 25 μg / ml concentration, and iNOS, COX-2, and TNF-a showed a significant decrease at all concentrations of CHA compared to the control group. In inflammatory factor production, NO and TNF-a showed a significant decrease at all concentrations except 25 μg / ml concentration of CHA, and IL-1β showed a significant decrease at 100, 200 μg / ml concentration of CHA compared to the control group. IL-6 showed a significant decrease at all concentration of CHA compared to the control group. In protein phosphorylation level, ERK and p38 showed a significant decrease at all concentrations except 25 μg / ml concentration of CHA and JNK showed a significant decrease at all concentrations of CHA compared to control group. 2. In vivo experiment In mRNA expression level, iNOS, COX-2 and TNF-a showed a significant decrease in all administration groups of CHA compared to the control group. In Inflammatory factor production, IL-6, IL-1β and TNF-a showed a significant decrease in all the administration groups of CHA. In protein phosphorylation level, ERK, JNK, and p38 showed a significant decrease in all the administration groups of CHA. In the immune cells, leukocytes and lymphocytes showed a significant decrease in all the administration groups of CHA. Conclusions : This study shows that CHA has antioxidant and inflammatory-control effects on LPS-induced RAW264.7 cells. It is hoped that further research will be conducted on the individual mechanisms of Lonicera japonica Thunberg, Forsythia viridissima Lindley, and Taraxacum platycarpum H. Dahlstedt.

      • 인간 재조합 인터루긴-32 면역조절작용에 대한 유세포 분석

        이광수,김영관,채정일,심정현,김은미,강형식,김수현,윤도영,명평근 충남대학교 생물공학연구소 2006 생물공학연구지 Vol.12 No.-

        Xenotransplantation of porcine organs has the potential to overcome the severe shortage of human tissues and organ available for human transplantation. however, it remains various hurdles for clinical xenotransplantation. In pig and mouse xenotransplantation, porcine xenograft evoke a strong cellular rejection response in immunocompetent host and grafts are destroyed within a week. This cellular immune response could involved both T cells and NK cells. A number of groups have shown that human NK cells can recognize and damage porcine endothelial cells. In addition, human T cells can respond to porcine endothelial cells through both direct and indirect mechanisms. Cellular rejection of porcine tissues requires T cells, particularly CD4^(+) cells. A new cytokine recombinant human interleukin-32α,β(IL-32α,β) has a role innate and acquired immune system. In order to investigate the role of recombinant mouse IL-18 and recombinant human IL-32α,β in xenograft rejection, we transplanted the PK(15) cells to C57BL/6 mice with or without intraperitoneal injection of recombinant mouse IL-18 or recombinant human IL-32 α,β. It was analyzed the population of NK cell, T cell and B cell in the C57BL/6 mice transplanted with PK(15) cells and recombinant mouse IL-18 or recombinant human IL-32α,β by flow cytometry analysis. As a result, lymph node and thymus of PK15/IL18, PK15/IL32α and PK15/IL32β injected group were increased to T cell activation population than normal injected groups. CD8^(+) T cells were decreased in lymph node of PK15/IL18, PK15/IL32α and PK15/IL32β injected groups. CD4^(+) T cells were increased in lymph node cell of PK15/IL32α and PK15/IL32β injected group and also, B cell population were increased in lymph node cell and spleen of PK15/IL18, PK15/IL32α and PK15/IL32β injected group. Therefore, we suggest that recombinant mouse IL-18 and recombinant human IL-32α,β suppress xenograft rejection in cellular xenotransplantation.

      • RSV 와 인플루엔자 바이러스 A 형 감염에 의해 천명을 보이는 소아와 천식 소아에서 비인두 흡인액의 Interleukin-5 와 Interleukin-γ 치의 비교

        오재원,이하백,김창렬,염명걸,문수지,박일규,강정옥 대한 소아알레르기 및 호흡기학회 1999 소아알레르기 및 호흡기학회지 Vol.9 No.2

        목 적 : 호흡기 바이러스 감염은 소아에서 천식을 악화시키는 것으로 잘 알려져 있다. 그러나 영유아기의 천식이나 천명발생에 있어서 호홉기 바이러스의 역할에 대해서는 명확하게 밝혀져 있지 않다. 소아기의 천명이 천식과 달리 하나의 독립된 질환인지, 아니면 같은 질환으로 달리 표현되는 것인지 논란이 되어왔다. 이에 본 저자들은 호흡기 바이러스 감염과 천명과의 상관관계와 기전을 이해하기 위하여 RSV 감염이나 influenza A 바이러스 감염에 의해 천명이 있는 소아와 바이러스가 증명되지 않고 천명이 있는 천식소아에서의 비인두 흡인액의 IL-5와 IFN-γ치를 측정하여 비교하였다. 방 법 : 호흡기 바이러스 감염군 38명(RSV감염군 21명, influenga A virus 감염군 17명), 바이러스가 증명되지 않은 천식환아군 12명, 정상 대조군 16명을 대상으로 double sandwich ELISA를 이용하여 비인두 흡인액에서 IL-5와 IFN-γ치를 측정하여 비교하였다. 결 과 : RSV 감영군에서 비인두 흡인액의 IL-5 평균치가 influenza A 바이러스군의 평균치보다 의미있게 높았으며, 천식군보다도 높은 양상을 보이나 의미있는 차이는 없었다 반면, influenza A 바이러스 감염군의 비인두 흡인액의 IFN-γ치가 RSV군에 비해 의미있게 높았으나 천식환아군이나 정상군에 비해 의미있게 높지는 않았다. 비인두 흡입액에서 IL-5와 IFN-γ치간의 상관관계는 없었다. 결 론 : RSV 감염군은 influenza A 바이러스 감염군에 비해 Th2 반응이 우세한 것으로 추정되며, 반면에 influenza A virus 감염군은 Th1 반응을 보이는 것을 알 수 있다. Background : Infection with respiratory virus has been shown to exacerbate asthma. However, the role of a respiratory virus in the pathogenesis of chronic asthma and/or wheezing in young children has not been clearly defined. And it also has been debated whether virus-induced wheezing in young children is an entity different from allergic asthma, or just a different expression of the same disease. In this study, we attempted to evaluate the importance of eosinophilic inflammation, comparing IL-5 and IFN-γ levels in nasopharyngeal secretions in wheezing children with or without viral infection and the controls. Methods : We compared IL-5 and IFN-γ levels in nasopharyngeal secretions from 38 non-asthmatic wheezing children with viral infections (RSV in 21 children, influenza A virus in 17 children), 12 asthmatic children without viral infections and 16 children as the controls. Results : The present study reported that RSV infection in children induced more releasing of IL-5 in nasopharyngeal secretions than the influenza A virus infected ones and the controls. On the other hand, the releasing of IFN-γ levels in nasopharyngeal secretions from children with influenza A virus infection was significantly higher than those of the children with RSV infection or asthmatic children. Conclusion : RSV infection in children may play a role in the immune response toward a Th2 phenotype as increasing IL-5 secretion in nasopharyngeal secretion. Increased IFN-γ production in response to the influenza A virus infection may be related to the effective Th1 responses.

        PLZF+ Innate T Cells Support the TGF-beta-Dependent Generation of Activated/Memory-Like Regulatory T Cells

        Kyeong-Cheon Jung,Byung Hyun Kang,Hyo Jin Park,Hi Jung Park,Jae-il Lee,Seong Hoe Park 한국분자세포생물학회 2016 Molecules and cells Vol.39 No.6

        PLZF-expressing invariant natural killer T cells and CD4 T cells are unique subsets of innate T cells. Both are selected via thymocyte-thymocyte interaction, and they contribute to the generation of activated/memory-like CD4 and CD8 T cells in the thymus via the production of IL-4. Here, we investigated whether PLZF+ innate T cells also affect the development and function of Foxp3+ regulatory CD4 T cells. Flow cytometry analysis of the thymus and spleen from both CIITA transgenic C57BL/6 and wild-type BALB/c mice, which have abundant PLZF+ CD4 T cells and invariant natural killer T cells, respectively, revealed that Foxp3+ T cells in these mice exhibited a CD103+ activated/memory-like phenotype. The frequency of CD103+ regulatory T cells was considerably decreased in PLZF+ cell-deficient CII-TATgPlzflu/lu and BALB/c.CD1d−/− mice as well as in an IL-4-deficient background, such as in CIITATgIL-4−/− and BALB/ c.IL-4−/− mice, indicating that the acquisition of an activated/memory-like phenotype was dependent on PLZF+ innate T cells and IL-4. Using fetal thymic organ culture, we further demonstrated that IL-4 in concert with TGF- enhanced the acquisition of the activated/memory-like phenotype of regulatory T cells. In functional aspects, the activated/memory-like phenotype of Treg cells was directly related to their suppressive function; regulatory T cells of CIITATgPIV-/- mice more efficiently suppressed ovalbumin-induced allergic airway inflammation compared with their counterparts from wild-type mice. All of these findings suggest that PLZF+ innate T cells also augmented the generation of activated/memory-like regulation via IL-4 production.

        PLZF<sup>+</sup> Innate T Cells Support the TGF-β-Dependent Generation of Activated/Memory-Like Regulatory T Cells

        Kang, Byung Hyun,Park, Hyo Jin,Park, Hi Jung,Lee, Jae-Il,Park, Seong Hoe,Jung, Kyeong Cheon Korean Society for Molecular and Cellular Biology 2016 Molecules and cells Vol.39 No.6

        PLZF-expressing invariant natural killer T cells and CD4 T cells are unique subsets of innate T cells. Both are selected via thymocyte-thymocyte interaction, and they contribute to the generation of activated/memory-like CD4 and CD8 T cells in the thymus via the production of IL-4. Here, we investigated whether $PLZF^+$ innate T cells also affect the development and function of $Foxp3^+$ regulatory CD4 T cells. Flow cytometry analysis of the thymus and spleen from both CIITA transgenic C57BL/6 and wild-type BALB/c mice, which have abundant $PLZF^+$ CD4 T cells and invariant natural killer T cells, respectively, revealed that $Foxp3^+$ T cells in these mice exhibited a $CD103^+$ activated/memorylike phenotype. The frequency of $CD103^+$ regulatory T cells was considerably decreased in $PLZF^+$ cell-deficient $CIITA^{Tg}Plzf^{lu/lu}$ and $BALB/c.CD1d^{-/-}$ mice as well as in an IL-4-deficient background, such as in $CIITA^{Tg}IL-4^{-/-}$ and $BALB/c.IL-4^{-/-}$ mice, indicating that the acquisition of an activated/ memory-like phenotype was dependent on $PLZF^+$ innate T cells and IL-4. Using fetal thymic organ culture, we further demonstrated that IL-4 in concert with TGF-${\beta}$ enhanced the acquisition of the activated/memory-like phenotype of regulatory T cells. In functional aspects, the activated/ memory-like phenotype of Treg cells was directly related to their suppressive function; regulatory T cells of $CIITA^{Tg}PIV^{-/-}$ mice more efficiently suppressed ovalbumin-induced allergic airway inflammation compared with their counterparts from wild-type mice. All of these findings suggest that $PLZF^+$ innate T cells also augmented the generation of activated/memory-like regulation via IL-4 production.

      • Intracellular IL-4, IL-10, and IFN-gamma levels of leukemic cells and bone marrow T cells in acute leukemia.

        Park, Hun Hee,Kim, Myungshin,Lee, Bong-Hee,Lim, Jihyang,Kim, Yonggoo,Lee, Eun Jung,Min, Woo Sung,Kang, Chang Suk,Kim, Won Il,Shim, Sang In,Han, Kyungja Institute for Clinical Science] 2006 Annals of clinical and laboratory science Vol.36 No.1

        <P>The quantitative levels of intracellular cytokines IL-4, IL-10, and IFN-gamma (ie, the number of bound PE-conjugated antibody molecules/cell) of leukemic cells and bone marrow T cells (bmT cells) of acute leukemia patients were analyzed by flow cytometry. One hundred, thirty-one (95 AML, 25 ALL, 11 ABL) patients were studied. The leukemic cell IL-4 level was highest in the monocytic AML group (1735 +/- 1056) and lowest in the dysplastic AML group (960 +/- 545). The IFN-gamma level was highest in the acute promyelocytic leukemia (APL) group (495 +/- 159), and lowest in the ALL group (252 +/- 119). The IL-10 level was not significantly different among the diagnosis groups. In bmT cells, the IL-10 level was highest in the dysplastic AML group (972 +/- 1049) and lowest in the APL group (397 +/- 352). The leukemic cell cytokine levels were lowest and bmT cell cytokine levels were highest in the dysplastic AML group. There were no significant correlations of these cytokine levels with 2-yr survival rate, complete remission (CR) rate, or relapse rate. The cytokine levels of bmT cells at the time of CR became normal and were not different among the diagnosis groups. In summary, leukemic cell and bmT cell cytoplasmic expression profiles of IL-4, IL-10, and IFN-gamma are characteristic for each diagnostic group of acute leukemia patients and the profiles of bmT cells are normal at the time of CR.</P>

      • Free Paper Session : Upper Gastrointestinal Tract 1 ; Prevalence And Risk Factors For Atrophic Gastritis And Intestinal Metaplasia

        ( Na Young Kim ),( Dong Ho Lee ),( Joo Sung Kim ),( Hyun Chae Jung ),( In Sung Song ),( Kyung Phil Kang ),( Jung Hoon Lee ),( Jae Il Chung ),( Hyun Cheul Choi ),( Taek Man Nam ),( Sang Hyup Lee ),( Yo 대한소화기학회 2007 SIDDS Vol.9 No.-

        Background/Aims: The prevalence of gastric cancer and Helicobacter pylori (Hp) infection is high in Korea. This study was performed to evaluate the prevalence rate of atrophic gastritis (AG) and intestinal metaplasia (IM) and their risk factors in the aspect of Hp virulence factors, environmental and host factors in normal population. Methods: The subjects consisted of 389, 135 H. pylori-negative and 254 H. pylori-positive. AG and IM were scored histologically by the Sydney classification in the antrum and body, respectively. Prevalence rate and bacterial factors such as cagA, vacA m1, m2, and oipA; environmental factors such as smoking, alcohol drinking; host factors such as genetic polymorphisms for IL-IB-511, IL-IRN, TNF-A, IL-10-592, IL-10-819, IL-10-1082, IL-8-251, IL-6-572, GSTP1, and p53 codon 72 were evaluated. Risk factors were calculated by multiple logistic regression analysis. Results: The prevalence rate of AG increased from 25%, 0% in the age of 20s, 45% and 22% in the 40s and 50% and 35% in the over 70s in the antrum and body, respectively (p<0.001). In case of IM it increased from 11.1% and 6.4% in the 30s up to 43% and 43% in over 70s in the antrum and body, respectively, (p<0.001). The positive rates of AG and IM were significantly higher in the Hp-positive than in the Hp-negative subjects. Multivariate analysis showed that the risk factors for AG were Hp infection, age ≥60, cagA and vacA m1 positive. In case of IM the risk factors were Hp infection, age ≥60, smoking, spicy food, occupation (unemployed or non professional vs. professional), IL6-572 G carrier over C/C and IL10-592 C/A vs. A/A. Conclusions: The prevalence rate of AG and IM increased proportional to age. The most risk factor for AG and IM was Hp infection. Bacterial factors were important for AG but environmental and host factors were rather important in case of IM.

        Regulation of UVB-Induced IL-8 and MCP-1 Production in Skin Keratinocytes by Increasing Vitamin C Uptake via the Redistribution of SVCT-1 from the Cytosol to the Membrane

        Kang, Jae Seung,Kim, Ha Na,Jung, Da Jung,Kim, Jee Eun,Mun, Ga Hee,Kim, Yeong Seok,Cho, Daeho,Shin, Dong Hoon,Hwang, Young-Il,Lee, Wang Jae Williams & Wilkins 2007 The Journal of investigative dermatology Vol.127 No.3

        It is well known that UVB (290–320 nm) induces inflammation in skin by the transcription and release of cytokines and chemokines from skin keratinocytes. In addition, it is considered that intracellular reactive oxygen species (ROS) plays an important role in UVB-induced inflammatory response in the skin. Therefore, we investigated the effect of vitamin C, a potent antioxidant, on the regulation of UVB-induced skin inflammation via the modulation of chemokines production. Vitamin C uptake into keratinocytes is increased by UVB irradiation in a time- and dose-dependent manner through the translocation of sodium-dependent vitamin C transporter-1 (SVCT-1), a vitamin C-specific transporter, from the cytosol to the membrane. To evaluate the effect of vitamin C on the chemokine mRNA expression, we performed RNase protection assay. As a result, there was a remarkable change in chemokine mRNA expression, especially IL-8 and monocyte chemoattractant protein (MCP)-1 expression. In addition, increased IL-8 and MCP-1 mRNA expressions were suppressed by vitamin C treatment. We also confirmed the results of protein levels measured by ELISA. Taken together, vitamin C uptake is increased in UVB-irradiated keratinocytes through the translocation of SVCT-1 and regulates inflammatory response in the skin via the downregulation of IL-8 and MCP-1 production.Journal of Investigative Dermatology (2007) 127, 698–706. doi:10.1038/sj.jid.5700572; published online 28 September 2006

        Hair-Loss Preventing Effect of Grateloupia elliptica

        ( Jung Il Kang ),( Sang Cheol Kim ),( Sang Chul Han ),( Hye Jin Hong ),( You Jin Jeon ),( Bo Ra Kim ),( Young Sang Koh ),( Eun Sook Yoo ),( Hee Kyoung Kang ) 한국응용약물학회 2012 Biomolecules & Therapeutics(구 응용약물학회지) Vol.20 No.1

        This study was conducted to evaluate the effect of Grateloupia elliptica, a seaweed native to Jeju Island, Korea, on the prevention of hair loss. When immortalized rat vibrissa dermal papilla cells were treated with extract of G. elliptica, the proliferation of dermal papilla cells significantly increased. In addition, the G. elliptica extract significantly inhibited the activity of 5α-reductase, which converts testosterone to dihydrotestosterone (DHT), a main cause of androgenetic alopecia. On the other hand, the G. elliptica extract promoted PGE2 production in HaCaT cells in a dose-dependent manner. The G. elliptica extract exhibited particularly high inhibitory effect on LPS-stimulated IL-12, IL-6, and TNF-α production in lipopolysaccharide (LPS)-stimulated bone marrow-derived dendritic cells. The G. elliptica extract also showed inhibitory activity against Pityrosporum ovale, a main cause of dandruff. These results suggest that G. elliptica extract has the potential to treat alopecia via the proliferation of dermal papilla, 5α-reductase inhibition, increase of PGE2 production, decrease of LPS-stimulated pro-inflammatory cytokines and inhibitory activity against Pityrosporum ovale.

      • RSV나 인플루엔자 A형 바이러스에 감염된 비천식 소아에게 비인두 흡인액의 Interleukin - 11 , Interferon - γ치와 eosinophil cationic protein 치의 비교

        오재원(Jae Won Oh),이하백(Ha Baik Lee),박일규(Il Kyu Park),강정옥(Jung Oak Kang) 대한천식알레르기학회 2000 천식 및 알레르기 Vol.20 No.1

        N/A Background: Infection with respiratory virus has been shown to exacerbate asthma in humans. However, the role of a respiratory virus in the pathogenesis of chronic asthma and/or wheezing in young children has not been clearly defined. The objective of this study was to determine whether respiratory virus infections such as RSV, and influenza A virus are related to the productions of IL-11, IFN-γ, and ECP levels in nasopharyngeal secretions. Method: We compared IL-11, IFN-γ, and ECP levels in nasopharyngeal secretions from 38 non-asthmatic wheezing children with viral infections (RSV in 21 children, influenza A virus in 17 children), and 16 non-asthmatic healthy children who were included as the controls. IL-11, and IFN-y levels were analysed by ELISA. ECP concentrations were measured by monoclonal antibody-based fluorometric assay. Result. RSV infection in children induced a greater release of IL-11 in nasopharyngeal secretions than in influenza A virus infection, and in the controls. The release of IFN-γ levels in nasopharyngeal secretions from children with influenza A virus infection was significantly higher than in nasopharyngeal secretions from children with RSV. ECP levels of subjects with viral infection were significantly higher than in control children. Conclusion. This study demonstrated that RSV is a potent inducer of IL-11 elaboration in nasal epithelium and that IL-11 is an important mediator in the pathogenesis of RSV infection. Increased IFN-γ production in response to the influenza A virus infection may be related to effective Th1 responses.
