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.

<P>T cell stimulation via glucocorticoid-induced tumor necrosis factor receptor (TNFR)-related protein (GITR) elicits antitumor activity in various tumor models; however, the underlying mechanism of action remains unclear. Here we demonstrate a crucial role for interleukin (IL)-9 in antitumor immunity generated by the GITR agonistic antibody DTA-1. IL-4 receptor knockout (Il4ra(-/-)) mice, which have reduced expression of IL-9, were resistant to tumor growth inhibition by DTA-1. Notably, neutralization of IL-9 considerably impaired tumor rejection induced by DTA-1. In particular, DTA-1-induced IL-9 promoted tumor-specific cytotoxic T lymphocyte (CTL) responses by enhancing the function of dendritic cells in vivo. Furthermore, GITR signaling enhanced the differentiation of IL-9-producing CD4(+) T-helper (T(H)9) cells in a TNFR-associated factor 6 (TRAF6)- and NF-kappa B-dependent manner and inhibited the generation of induced regulatory T cells in vitro. Our findings demonstrate that GITR co-stimulation mediates antitumor immunity by promoting T(H)9 cell differentiation and enhancing CTL responses and thus provide a mechanism of action for GITR agonist-mediated cancer immunotherapies.</P>

연구배경 : 정신분열병이 유전적이라고 제시하는 많은 역학 연구와 유전자 연구에도 불구하고, 이 질환의 유전방식과 질병유전자는 밝혀져 있지 않다. 본 연구에서는 정신분열병과 22번 염색체 장완의 11.2-12부위에 위치한 Interleukin-2수용체 β chain 유전자간에 유전적 연합을 조사하고자 정신분열병 환자 93명과 정상대조군 97명 대상으로 중합효소연쇄반응을 이용하여 Interleukin-2 수용체 β chain (IL-2Rβ) 유전자의 다형성 분포를 조사하였다. 연구방법 : 환자군은 DSM-Ⅲ-R 진단기준에 따라 임상아형(망상형, 붕괴형, 미붕괴형, 잔류형)으로 분류하였다. 음성 및 양성 정신분열병으로 분류하기위해 Positive and Negative Syndrome Scale(PANSS)을 사용하였다. Genomic DNA를 전혈 임파구에서 추출한 후, IL-2Rβ 유전자좌를 분석하기 위해 dinucleotide(GT)n 염기배열순서를 중합효소연쇄반응을 이용하여 증폭시켰다. 연구결과 : IL-1Rβ의 대립유전자는 모두 8가지 종류이고, guanine-thymine의 반복된 149 염기쌍을 시작으로 151, 153, 155, 157, 159, 161, 163 염기쌍의 형태를 보였다. 정신분열병 환자군과 정상대조군간에 도형접합체 및 이형접합체 빈도의 유의한 차이는 없었다. 환자군과 정상대조군의 대립유전자 분포의 빈도는 통계적으로 유의한 차이가 없었다. 더욱이 각각의 대립유전자 분포에서도 양군간 유의한 차이는 없었다. 또한 동질의 아형으로 분류해 보기위해 임상아형, 양성 및 음성증상군, 가족력의 유무에 따라 비교적 동질적인 표현형을 가진 집단으로 나눈 후 대립유전자 분포를 비교해 보았으나 통계적으로 유의한 차이를 보이지 않았다. 결 론 : 본 연구에서는 Interleukin-2 수용체 β chain 유전자가 정신분열병의 병인론에 관련된다는 가설을 지지할 만한 긍정적 소견을 얻지 못했다. Background : While a significant genetic predisposition to schizophrenia has been proposed, the mode of inheritance or nature of etiological factors is unknown. Previous reports of a genome-wide survey for schizophrenia susceptibility genes have indicated a possible region of linkage on chromosome 22. In order to test the possibility that the interleukin-2 receptor β chain(IL-2Rβ) gene on chromosome 22 is of etiological importance in schizophrenia, a case-control association study was conducted. Methods : Subjects were ninety-three schizophrenic patients with a diagnosis of schizophrenia by DSM-Ⅲ-R criteria and ninety-seven normal controls, Schizophrenic patients were divided by clinical phenotypes such as DSM-Ⅲ-R diagnostic subtypes, positive and negative symptoms, and family history so as to increase the homogeneity of schizophrenics. Genomic DNA was extracted from whole blood lymphocytes according to standard procedures. The DNA was used to study a dinucleotide repeat in the IL-2Rβ gene. To reveal the dinucleotide polymorphism. genomic DNA of subjects was amplified by polymerase chain reactions(PCR). Results : At the IL-2Rβ gene locus, all the previously reported alleles(eight different alleles) of a dinucleotide polymorphism were identified. There was no significant difference between number of heterozygosity in schizophrenic patients and in normal controls. There was no significant difference in the distribution of frequencies of alleles between schizophrenics and normal controls. In addition, there was no significant difference in the allele frequencies among subtypes of schizophrenic patients according to DSM-Ⅲ-R diagnostic subtypes, positive and negative symptoms, and family history. Conclusion : The present study did not detect a difference in frequencies of alleles of a dinucleotide polymorphism at the IL-2Rβ gene locus between schizophrenic patients and normal controls. These results do not supports an evidence that IL-2Rβ gene plays, a major role in the etiology of schizophrenia.

Lee, Youngseop,Kim, Sun Kwang,Kim, Yangseok,Lee, Hyejung,Shin, Min-Kyu,Hong, Moo-Chang,Min, Byung-Il,Bae, Hyunsu WHO COLLABORATING CENTRE FOR TRADITIONAL MEDICINE 2007 東西醫學硏究所 論文集 Vol.2007 No.-

Our previous study demonstrated that successive electroacupuncture (EA) at ST36 acupoint reduces IgE production in BALB/c mice immunizec with 2,4-dinitrophenylated keyhole limpet protein (DNP-KLH) by suppression of the Th2 cell lineage development. Here, we report that pretreatment of phentolamine (α-adrenoceptor antagonist, 10 mg/kg, i.p.) completely blocks the EA-induced suppression of antigen-specifie and total IgE levels in serum and IL-4 production in anti-CD3 mAb-activated splenocytes in DNP-KLH immunized mice. The results suggest that α-adrenoceptor play an important role in mediating the suppressive effects of EA on IgE production and Th2 cell response in DNP-KLH immunized mice.

Characterization of age‐associated exhausted CD 8 ⁺ T cells defined by increased expression of Tim‐3 and PD ‐1

Lee, Kyoo‐,A,Shin, Kwang‐,Soo,Kim, Ga‐,Young,Song, You Chan,Bae, Eun‐,Ah,Kim, Il‐,Kyu,Koh, Choong‐,Hyun,Kang, Chang‐,Yuil John Wiley and Sons Inc. 2016 Aging Cell Vol.15 No.2

<P><B>Summary</B></P><P>Aging is accompanied by altered T‐cell responses that result in susceptibility to various diseases. Previous findings on the increased expression of inhibitory receptors, such as programmed cell death protein 1 (PD‐1), in the T cells of aged mice emphasize the importance of investigations into the relationship between T‐cell exhaustion and aging‐associated immune dysfunction. In this study, we demonstrate that T‐cell immunoglobulin mucin domain‐3 (Tim‐3), another exhaustion marker, is up‐regulated on aged T cells, especially CD8<SUP>+</SUP> T cells. Tim‐3‐expressing cells also produced PD‐1, but Tim‐3<SUP>+</SUP>PD‐1<SUP>+</SUP>CD8<SUP>+</SUP> T cells had a distinct phenotype that included the expression of CD44 and CD62L, from Tim‐3<SUP>−</SUP>PD‐1<SUP>+</SUP> cells. Tim‐3<SUP>+</SUP>PD‐1<SUP>+</SUP>CD8<SUP>+</SUP> T cells showed more evident properties associated with exhaustion than Tim‐3<SUP>−</SUP>PD‐1<SUP>+</SUP>CD8<SUP>+</SUP> T cells: an exhaustion‐related marker expression profile, proliferative defects following homeostatic or TCR stimulation, and altered production of cytokines. Interestingly, these cells produced a high level of IL‐10 and induced normal CD8<SUP>+</SUP> T cells to produce IL‐10, which might contribute to immune dysregulation in aged mice. The generation of Tim‐3‐expressing CD8<SUP>+</SUP> T cells in aged mice seems to be mediated by encounters with antigens but not by specific infection, based on their high expression of CD49d and their unbiased TCR Vβ usage. In conclusion, we found that a CD8<SUP>+</SUP> T‐cell population with age‐associated exhaustion was distinguishable by its expression of Tim‐3. These results provide clues for understanding the alterations that occur in T‐cell populations with age and for improving dysfunctions related to the aging of the immune system.</P>

<P><I>Lonicera japonica THUNB.</I>, which abundantly contains polyphenols, has been used as a traditional medicine for thousands of years in East Asian countries because of the anti-inflammation properties. This study aimed to investigate the anti-inflammatory mechanism of polyphenol components isolated from Korea <I>L. japonica T.</I> by nuclear factor-kappaB (NF-<I><I>κ</I></I>B) and mitogen-activated protein kinases (MAPKs) pathway. Polyphenols significantly decreased lipopolysaccharide- (LPS-) induced mRNA and protein expression of inducible nitric oxide synthase and cyclooxygenase-2, as well as mRNA expression of tumor necrosis factor-alpha, interleukin- (IL-) 1<I><I>β</I></I>, and IL-6. Moreover, polyphenols inhibited nuclear translocation of NF-<I><I>κ</I></I>B p65, phosphorylation/degradation of the inhibitor of <I><I>κ</I></I>B, and phosphorylation of p38 MAPK, whereas the extracellular signal-regulated kinase and Janus N-terminal kinase were not affected. These results indicate that polyphenol components isolated from Korea <I>L. japonica T.</I> should have anti-inflammatory effect on LPS-stimulated RAW 264.7 cells through the decrease of proinflammatory mediators expression by suppressing NF-<I><I>κ</I></I>B and p38 MAPK activity.</P>

An experiment was carried out to assess the effect of feed selenium-lysine (Se-Lys) supplementation on milk compositions and serum biochemical indices in Saanen dairy goats in Korea. A total of twelve 36 months old Saanen lactating dairy goats (47±6.21 kg) fed the similar dry matter intake twice a day at 2% of BW (DMI) (10.9% moisture of concentrate and 19% moisture of roughage), milk yield (2.5 kg/d) and parity (2) were randomly selected and subjected for the present study, divided into two groups with six goats in each group. The goats in the control group received rice hulls (10 g/ day) only, and did not receive Se-Lys; goats in the treatment group were fed 0.06 g of Se-Lys with 10 g of rice hulls every day before feeding roughage for six weeks. The milk sample was collected every week, and its compositions were analyzed. The results of the present study showed that there is no significantly increased milk production in Se-Lys treated group goats when compared with control group goats. But, Se-Lys treatment significantly increased the milk protein content (3.98±0.16%), fat (3.72±0.27%), lactose (4.07±0.14%), total solids (12.51±0.28%) and urea (14.42±1.45 mg/dl) content as compared to the control group goats (p<0.05). The somatic cell counts (207,740±28.81 cells/ml) were significantly lower in the Se-Lys treated group than in the control group (p<0.05). Also, the results of the current study showed that supplementation of Se-Lys were significantly decreased the blood biochemical indices of IL-6 (34.34±6.04 pg/ml), TNT-α (0.56±0.22 ng/ml), MDA (5.07±1.03 ng/ml), GPx-1 (9.07±5.17 ng/ml), sCD4 (2.64±1.02 ng/ml) and sCD8 (5.08±2.08 ng/ml) level when compared with without addition of Se-Lys group dairy goats (p<0.05). On the other hand, the selenoprotein P (1,580.18±127.62 ng/ml) level was significantly higher in Se-Lys supplemented group than in the control group (p<0.05). Based on the study results, it was concluded that feed Se-Lys supplementation may improve milk yield with positively improved protein, fat, lactose, total solids, urea content, and biochemical indices without negative effects on milk production traits.

Fermented Herbal Formulas KIOM-MA128 Ameliorate IL-6-Induced Intestinal Barrier Dysfunction in Colon Cancer Cell Line

Park, Kwang Il,Kim, Dong Gun,Lee, Bo Hyoung,Ma, Jin Yeul Hindawi Publishing Corporation 2016 MEDIATORS OF INFLAMMATION Vol.2016 No.-

<P>Inflammatory bowel disease (IBD) comprises Crohn's disease (CD) and ulcerative colitis (UC). IBD increases the risk of colorectal cancer (CRC), depending on the extent and duration of intestinal inflammation. Increased IL-6 expression has been reported in IBD patients, which may be associated with intestinal barrier function through discontinuous tight junction (TJ). KIOM-MA is a specific agent for allergic diseases and cancer, and it is composed of several plants; these herbs have been used in traditional oriental medicine. We fermented KIOM-MA, the product of KIOM-MA128, using probiotics to improve the therapeutic efficacy via the absorption and bioavailability of the active ingredients. In this study, we demonstrated that KIOM-MA/MA128 exhibited anticolitis effects via the modulation of TJ protein. Interleukin-6 resulted in a dose-dependent decrease in the TER and an increase in the FITC-dextran permeability; however, pretreatment with 400 <I>µ</I>g/ml KIOM-MA/MA128 resulted in a significant increase in the TER and a decrease in the FITC-dextran permeability via IL-6 induction. Furthermore, protein and mRNA TJ levels remained stable after pretreatment with 400 <I>µ</I>g/ml KIOM-MA/MA128. Moreover, KIOM-MA/MA128 suppressed the expression of PLC<I>γ</I>1 and PKC. Taken together, these findings suggest novel information and clue of the anticolitis effects of KIOM-MA128 via regulation of tight junction.</P>

Purpose: This study was performed to find out the effects of the Er:YAG laser (Key Laser) & Er,Cr:YSGG laser (Water Laser) on inflammatory tissues. Materials and Methods: It was performed on about 20 g, 6 weeks male ICR mouses. They were grouped into the control (negative), the inflammation induced 'control'(positive), Er,Cr:YSGG laser exposured group after inducing inflammation, Er:YAG lasere exposured group after inducing inflammation each 15 mouses. The mouses were applicated 0.5% DNFB 1 cc on ear skin twice a day for 4 days until symptom expression. After laser exposure, ear tissues were extracted and defined gene expression by RT-PCR. Then, tissue staining, lymphocytes observation, electromicroscophic laboratory were carried out. Results: Interleukin-$1{\beta}$ was expressed much less in the A-laser exposed group. Interleukin-$1{\beta}$ & Tumor Necrosis Factor-${\alpha}$ were expressed 7 times lesser in the A-laser exposed group. The number of Lymphocytes related to inflammation was decreased rapidly in the A-laser exposed group in vivo. he number of cavity recovered normal was a little bigger in the A-laser exposed group after 5 days Conclusion: The expression of IL-$1{\beta}$ & TNF-${\alpha}$, hitologic change, observation with electron microscope shows that Erbium laser exposure causes lesser inflammation with A-laser rather than B-laser.
