Koi herpesvirus (KHV), also known as Cyprinid herpes virus 3 (Cyprinid 3) is lethal disease in common carp and koi (Cyprinus carpio). Two different groups (KK and RK) were infected KHV by intraperitoneal injection. Fish for gene expression analysis were sampled at 0 h, 12 h, 24 h, 48 h and 72 h post infection (p.i). The results showed that two immune related gene, Interferons (INFs) ${\alpha}{\beta}$ and Interleukin (IL)-12 p35 induced a high response in RK. The IL-12 p35 cytokine and Toll-like receptor (TLR) 9 were significantly high expressed on 48 h post infection (p.i) in RK as compared to the KK. The histopatological examination reveals focal necrosis in liver and infiltrate of lymphocytes in spleen of KK as compared to the RK. In immunohistochemistry analysis, the KHV protein high expressed in the infected kidney cell and slenocyte of KK. Therefore, the expression of IL-12 p35, IFN ${\alpha}{\beta}$ and TLR 9 may provide a potentially genes related with KHV resistance in Koi and red common carp ${\times}$ koi.

Microglial activation is thought to play a role in the pathogenesis of many brain disorders. Therefore, understanding the response of microglia to noxious stimuli may provide insights into their role in disorders such as stroke and neurodegeneration. Many genes involved in this response have been identified individually, but not systematically. In this regards, the microarray system permitted to screen a large number of genes in biological or pathological processes. Therefore, we used microarray technology to evaluate the effect of oxygen glucose deprivation (OGD) and reperfusion on gene expression in microglia under ischemia-like and activating conditions. Primary microglial cultures were prepared from postnatal mice brain. The cells were exposed to 4 hrs of OGD and 1 h of reperfusion at $37^{\circ}C$. Isolated mRNA were run on GeneChips. After OGD and reperfusion, ＞2-fold increases of 90 genes and ＞2-fold decrease of 41 genes were found. Among the genes differentially increased by OGD and reperfusion in microglia were inflammatory and immune related genes such as prostaglandin E synthase, $IL-1{\beta}$, and $TNF-{\alpha}$. Microarray analysis of gene expression may be useful for elucidating novel molecular mediators of microglial reaction to reperfusion injury and provide insights into the molecular basis of brain disorders.

IL-18 production may enhance immune system defense against KG-1 cells ; NB4 cells, which are associated with good prognosis, do not produce IL-18. In this study, we treated KG-1 cells with IL-18 and used microarray technology to assess subsequent effects on gene expression. In UniGene-array of 7488 human genes, expression of 57 genes, including stress related genes, increased at least 2-fold, whereas expression of 48 genes decreased at least 2-fold. Following exogenous exposure of KG-1 cells to IL-18, expression of CRYGC, $NF{\kappa}BIA$ and NACA gene were monitored. The latter is a transcriptional coactivator potentiating c-Jun-mediated transcription.$NF{\kappa}BIA$ is an inhibitor of $NF{\kappa}B$, and affects growth regulation, apoptosis and hypoxic stress. Studies, such as this one, are beginning to clarify the differences between cells associated with good and bad cancer prognoses, which may ultimately assist in medical treatment for acute myeloid leukemia.

Exosomes are double phospholipid membrane vesicles that are synthesized and secreted by a variety of cells, including T cells, B cells, dendritic cells, immune cells, are extracellular vesicles. Recent studies have revealed that exosomes can play a significant role in under both physiological and pathological conditions. They have been implicated in regulation of inflammatory responses, immune response, angiogenesis, tissue repair, and antioxidant activities, particularly in modulating immunity in autoimmune diseases (AIDs). Moreover, variations in the expression of exosome-related substances, such as miRNA and proteins, may not only offer valuable perspectives for the early warning, and prognostic assessment of various AIDs, but may also serve as novel markers for disease diagnosis. This article examines the impact of exosomes on the development of AIDs and explores their potential for therapeutic application.

To investigate the effects of repeated immobilization-stress challenge on the the hypothalamic-pituitary-adrenal axis, the genomic transcriptome in the adrenal cortex of immobilization-stressed mouse was analyzed by using a cDNA microarray. Mice were subjected to immobilization stress for 2 h per day for 5 consecutive d. With a 4.0-fold cutoff of arbitrary criteria, the expression levels of 168 out of 41,174 genes were significantly modulated in the adrenal cortex by stress when comparing the control and experimental groups. These genes were related to apoptosis, cell cycle, immune response, inflammatory responses, and signal transduction, and thus may be used as potential targets for the development of therapeutics for chronic stress or depression. Six significant genes among these were selected for real time polymerase chain reaction analysis to confirm the change of their expression levels. The gene for phospho 1 was also further investigated because its expression showed the greatest fold-change.

Mesenchymal stem cells (MSCs) effectively reduce airway inflammation and regenerate the alveolus in cigarette- and elastase-induced chronic obstructive pulmonary disease (COPD) animal models. The effects of stem cells are thought to be paracrine and immune-modulatory because very few stem cells remain in the lung one day after their systemic injection, which has been demonstrated previously. In this report, we analyzed the gene expression profiles to compare mouse lungs with chronic exposure to cigarette smoke with non-exposed lungs. Gene expression profiling was also conducted in a mouse lung tissue with chronic exposure to cigarette smoke following the systemic injection of human cord blood-derived mesenchymal stem cells (hCB-MSCs). Globally, 834 genes were differentially expressed after systemic injection of hCB-MSCs. Seven and 21 genes, respectively, were up-and downregulated on days 1, 4, and 14 after HCB-MSC injection. The Hbb and Hba, genes with oxygen transport and antioxidant functions, were increased on days 1 and 14. A serine protease inhibitor was also increased at a similar time point after injection of hCB-MSCs. Gene Ontology analysis indicated that the levels of genes related to immune responses, metabolic processes, and blood vessel development were altered, indicating host responses after hCB-MSC injection. These gene expression changes suggest that MSCs induce a regeneration mechanism against COPD induced by cigarette smoke. These analyses provide basic data for understanding the regeneration mechanisms promoted by hCB-MSCs in cigarette smoke-induced COPD.

We have characterized full-length cDNA encoding Gall-6-tox protein, which was cloned from the fat body of the immunized Galleria mellonella larvae. The cloned cDNA of Gall-6-tox consists of 1301 nucleotides and contained an open reading frame of 891 nucleotides corresponding to a protein of 296 residues that includes a putative 16-residue signal sequence and a 280-residue mature peptide with a calculated mass of 30,707.73 Da. The deduced mature peptide contains conserved tandem repeats of six cysteine-stabilized alpha beta ($Cs{\alpha}{\beta}$) motifs, which was detected in scorpion toxins and insect defensins. In the sequence homology search, mature Gall-6-tox showed 34% and 28% amino acid sequence homology with Bomb-6-tox from Bombyx mori and Spod-11-tox from Spodoptera frugiperda, respectively. Gall-6-tox orthologs were only found in Lepidopteran species, indicating that this new immune-related gene family is specific to this insect order. RT-PCR analysis revealed that Gall-6-tox was expressed primarily in the larval fat bodies, hemocytes, and midgut against invading bacteria into hemocoel. Moreover, the expression time course of Gall-6-tox was examined up to 24 h in the fat bodies and midgut after injection of E. coli. Altogether, these results suggest that Gall-6-tox is derived from defensins and Gall-6-tox may play a critical role in Lepidoptera immune system.

This experiment was conducted to investigate the genetic effects of candidate genes on the growth of spleen and liver tissues using dietary Curcuma longa (C. longa) supplementation. Expression analyses of candidate genes regarding animal growth was performed in order to determine the factors affecting the growth related to immune components of Curucumin, Turmerone, and Zingiberene as the bile secretion Paratolyl methyl carbinol (PTMC). The animals were divided into four groups of five chicks supplied with experimental diets of C. longa at 0.25, 0.5 and 1% and controls. The 19 growth-related genes were known to cell maturation, differentiation significant expression patterns in this analysis. Expression of growth response-related genes in chicks supplemented with 1% of C. longa showed better growth performance than chicks with 0.25 and 0.5% in spleen (p<0.05). The IGF1, MSTN, POU1F1, ADCYAP1 gene were known to central roles in mediating gonadotropin function, regulating steroidogenesis and promoting oocyte growth and maturation. Sex steroids, androgen and estrogen can affect sex differentiation and also can affect muscle development. On the other hand, GHSR and FABP3 gene showed significant expression patterns in this analysis. The results would be used as basic information for the variation of growth-related genes expression on the cell growth, sex cell growth, and sex hormones according to dietary supplementation with C. longa in chickens.

저수온기만 넙치에 대량 폐사를 일으키는 바이러스성 출혈성 패혈증을 폐사가 발생하는 $15^{\circ}C$, 폐사가 발생하지 않는 $20^{\circ}C$에서 인공감염시켜 넙치의 면역 유전자 발현 profile을 cDNA microarray 분석하였으며, 특히 저수온기에 폐사가 나타나는 원인을 면역 유전자 발현과 관련시켜 알아보고자 하였다. $15^{\circ}C$, $20^{\circ}C$의 감염 세포구에 공통으로 발현되는 유전자는 MHC class I, IL-8, myeloperoxidase 및 endonuclease G-like 유전자로 모든 세포표면에 존재하여 항원을 제시하거나 호중구 주화성을 자극하는 유전자들이었다. 항원 가공 및 제시, 항체 생성에 관여하는 MHC class II, immunoglobulin (Ig)과 retinoblastoma 등의 유전자는 $20^{\circ}C$에서는 발현이 증가하였으나 $15^{\circ}C$에서는 발현이 감소되었다. 이로부터 폐사가 발생하지 않는 $20^{\circ}C$는 바이러스 감염초기의 항원 제시, MHC class I과 II에 의한 항원제시, apoptosis 및 이후의 항체 생산이 정상적으로 이루어져 폐사가 발생하지 않는 것으로 생각되었다. 그러나 폐사가 발생하는 $15^{\circ}C$에서는 MHC class I매개의 항원 제시와 탐식 작용등의 선천 면역은 이루어지나 macrophage에 의한 MHC class II매개의 항원 제시와 apoptosis저하, 항체 생산 관련 유전자의 발현저하가 관찰되어 초기 macrophage에 의한 항원제시의 실패로 적응 면역이 제대로 활성화되지 않아 폐사가 발생한 것으로 사료된다.

Objective: The goal of this study was to determine the anti-asthma mechanism of SF on TNF-${\alpha}$ induced activation on A549 (human type II-like epithelial) cells. Using oligonucleotide microarray, we sought to establish the molecular mechanism of the protective effects of SF on A549 cells. Material & Methods : Cells were cultured in three different conditions: 1) negative control group was cultured in normal condition of DMEM, 2) positive control group was activated with TNF-${\alpha}$, IL-4. and IL-1${\beta}$, and 3) SF treated group was previously treated with 0.1${\mu}g/ml$ SF after TNF-${\alpha}$, IL-4. and IL-1 activation. Cells of positive control and SF treated groups were cultured for 30 min, 1hr, 3hr and 6hr. Results : The comparative analysis of the gene expression profile revealed that proinflammatory cytokines such as IL1F8, IL1F9, IL1R1. IL1RN, IL1RAPL1, IL8, TNFRSF4, TNFSF10c, TNFSF13, TRAF5, and TRAF7 and inflammation-related genes including MMP2, MMP11, MMP14, MMP15, MMP16, MMP19, MMP25, and MMP27 were down regulated with SF treatment. Cell adhesion molecule genes such as ITGB1, ITGBL1, selectin P ligand, selectin E, ICAM2, ICAM3, VCAM1, PECAM, FCER1G and MMP28 genes were also down-regulated in SF treated A549 cells. Conclusion : These results suggest that the anti-asthmatic effects of SF could be mediated by regulating specific genes related with cell adhesion, proinflammatory cytokine and inflammation-related genes in A549 cells.
