  • Interleukin (IL)-15 is an essential immune-modulator with high potential for use in cancer treatment. Natural IL-15 has a low biological potency because of its short half-life and difficulties in mass-production. IL-15Rα, a member of the IL-15 receptor complex, is famous for its high affinity to IL-15 and its ability to lengthen the half-life of IL-15. We have double-transfected IL-15 and its truncated receptor IL-15Rα into CT26 colon cancer cells to target them for intracellular assembly. The secreted IL-15:IL-15Rα complexes were confirmed in ELISA and Co-IP experiments. IL-15:IL-15Rα secreting clones showed a higher anti-tumor effect than IL-15 secreting clones. Furthermore, we also evaluated the vaccine and therapeutic efficacy of the whole cancer-cell vaccine using mitomycin C (MMC)-treated IL-15:IL-15Rα secreting CT26 clones. Three sets of experiments were evaluated; (1) therapeutics, (2) vaccination, and (3) long-term protection. Wild-type CT26-bearing mice treated with a single dose of MMC-inactivated secreted IL-15:IL-15Rα clones prolonged survival compared to the control group. Survival of MMC-inactivated IL-15:IL-15Rα clone-vaccinated mice (without any further adjuvant) exceeded up to 100%. This protection effect even lasted for at least three months after the immunization. Secreted IL-15:IL-15Rα clones challenging trigger anti-tumor response via CD4+ T, CD8+ T, and natural killer (NK) cell-dependent cytotoxicity. Our result suggested that cell-based vaccine secreting IL-15:IL-15Rα, may offer the new tools for immunotherapy to treat cancer.

  • Triacsin C, an inhibitor of acyl-CoA synthetase, is known to have antiatherosclerotic and vasodilatory activities. The aims of this study were to evaluate the effects of triacsin C on endotoxin-induced (lipopolysaccharide, LPS) inflammation in 3T3-L1 adipocytes and also to evaluate its synergistic effect with triacsin C and resveratrol, a potent antiinflammatory agent. Exposure to LPS for 18 hr increased secretion of IL-6 into the culture medium and mRNA expression of IL-6, MCP-1, TLR and iNOS. Pretreatment of triacsin C for 2 hr suppressed IL-6 accumulation in the medium and the induction of IL-6 expression by LPS, which was more effective than resveratrol treatment. The synergistic effect of triacsin C and resveratrol was found to reduce the expression of iNOS by LPS. However, neither triacsin C nor resveratrol affected the LPS-induced expression of MCP-1, TLR or iNOS. These findings indicate that triacsin C may be a local regulator of inflammation in the adipocyte, although detailed mechanisms are needed to elucidate this through further research.

  • Polyinosinic:polycytidylic acid (poly[I:C]) can stimulate Toll-like receptor 3 (TLR3) signaling pathways. In this study, DF-1 cells were treated with poly(I:C) at various concentrations and time points to examine the comparative expression patterns of innate immune response genes. The viability of DF-1 cells decreased from 77.41% to 38.68% when cells were treated different dose of poly(I:C) from 0.1 ㎍/mL to 100 ㎍/mL for 24 h respectively. The expressions of TLR3, TLR4, TLR7, TLR15, TLR21, IL1B, and IL10 were increased in dose- and time-dependent manners by poly(I:C) treatment. On the contrary, the expression patterns of interferon regulatory factors 7 (IRF7), Jun proto-oncogene, AP-1 transcription factor subunit (JUN), Nuclear Factor Kappa B Subunit 1 (NF-κB1), and IL8L2 were varied; IRF7 and IL8L2 were increasingly expressed whereas the expressions of JUN and NF-κB1 were decreased in a dose-dependent manner after they were early induced. In time-dependent analysis, IRF7 expression was significantly upregulated from 3 h to 24 h, whereas JUN and NF-κB1 expressions settled down from 6 h to 24 h after poly(I:C) treatment although they were induced at early time from 1 h to 3 h. Poly(I:C) treatment rapidly increased the expression of IL8L2 from 3 h to 6 h with a plateau at 6 h and then the expression of IL8L2 was dramatically decreased until 24 h after poly(I:C) treatment although the expression level was still higher than the non-treated control. These results may provide the basis for understanding host response to viral infection and its mimicry system in chickens.

  • To effectively purify of IL-1 inhibitor from human febrile urine, we have established monoclonal antibody that reacts with human recombinant interleukin l$\beta$(IL-1$\beta$). The antibody, designated ON-1, was highly specific to IL-1$\beta$ and no cross-reaction with other cytokines(IL-l$\alpha$ and IL-4) was observed. As the results of ELISA inhibition assay and Western blotting method, it was further identified that ON-1 had high binding specificity with IL-1$\beta$. IL-1 receptor binding material from febrile patient urine was effectively purified with affinity column chromatography which conjugated with ON-1. This urinary material inhibited the thymocyte proliferation in a dosedependent manner. IL-l$\beta$ induced thymocyte proliferation activity was inhibited to 67.3% at 6 $\mu\textrm{g}$ of the purified urinary material. The result may suggest that this urinary material the purified urinary material. The result may suggest that this urinary material will have antagonic effect on IL-1 action mechanism and act IL-l$\beta$ inhibitor.

  • Interleukin 32 (IL-32) is a recently identified cytokine that induces major proinflammatory cytokines such as $TNF{\alpha}$ and IL-$1{\beta}$, which play an important role in chronic inflammatory diseases. To antagonize the biological function of IL-32 in cells, we generated RNA aptamers that could bind specifically to IL-32 protein. The highest affinity aptamer, AC3-3, successfully antagonized IL-32 by abolishing the induction of $TNF{\alpha}$ in the human lung carcinoma cells expressing IL-32. This aptamer could be used as a potent and selective antagonist against IL-32 to further elucidate the roles of IL-32 in chronic inflammatory diseases, as well as a therapeutic agent.

  • The trophic factor Neuregulin-1 (NRG-1) plays a critical role in the development of the peripheral nervous system and the repair of nerve injuries. The regulation of neutrophil apoptosis by cytokine secretion from structural cells is an important process in inflammatory diseases, including asthma. This study aimed to investigate the relationship between NRG-1 and the alteration of neutrophil apoptosis by the regulation of cytokine release in the human lung epithelial BEAS-2B cells. Tumor necrosis factor-alpha (TNF-α) and interferon-gamma (IFN-γ) induce the increase in the release of interleukin (IL)-6, IL-8, and monocyte chemoattractant protein-1 (MCP-1). NRG-1 alone had no effect on the secretion of IL-6, IL-8, and MCP-1. However, co-treatment of TNF-α and IFN-γ with NRG-1 inhibited the secretion of IL-6, IL-8, and MCP-1 that had been increased by TNF-α and IFN-γ. Treatment with NRG-1 did not have a direct effect on neutrophil apoptosis. Co-treatment of TNF-α and IFN-γ with NRG-1 was not effective on suppression of neutrophil apoptosis due to TNF-α and IFN-γ. The supernatant of BEAS-2B cells after co-treatment of TNF-α and IFN-γ with NRG-1 suppressed the inhibition of neutrophil apoptosis that had been caused due to the supernatant treated with TNF-α and IFN-γ. Taken together, NRG-1 has an anti-inflammatory effect in an inflammatory milieu by the regulation of cytokine secretion and neutrophil apoptosis.

  • Six triterpenoid compounds, friedelin (1), $3{\alpha}$-hydroxy-2-friedelanone (2), canophyllol (3), oleanolic aldehyde acetate (4), ursolic acid (5), and pachysandiol A (6) were isolated from the methylene chloride soluble fraction of the roots of A. japonica. The chemical structures of compounds 1-6 were determined by the basis of physico-chemical properties and spectroscopic methods such as 1D and 2D NMR. These compounds were isolated from this plant for the first time. For the isolated compounds (1-3), the inhibitory effect of IL-6 production in TNF-$\alpha$ stimulated MG-63 was examined. Among the isolates, $3{\alpha}$-hydroxy-2-friedelanone (2) showed potent inhibitory effect on IL-6 production in TNF-$3{\alpha}$ stimulated MG-63.

  • Overexpression of interleukin (IL)-35 has been found in a variety of malignancies, but the expression status in gastric cancer has yet to be elucidated clearly. In the present study, positive expression of EBI3 and p35 was 63.3% and 70.0% of cases, respectively. EBI3 expression was strongly related with larger tumor size and invasion depth (P<0.05). Similarly, expression of p35 was also correlated with larger tumor size (P<0.05). These results indicate that IL-35 might be involved in growth of gastric cancer. Interestingly, EBI3 and p35 expressions were positive correlated with Ki-67 expression. Moreover, EBI3 immunoreactivity was associated with Bcl-2 staining. Our data suggest IL-35 is correlated with genesis of gastric cancer by regulating growth and apoptosis.
