Inonotus obliquus is one of the immune-regulatory substances and is recognized to play the role in the metabolic process of inflammation, allergy and immuntiy. The purpose of this study was to evaluate the effects of water extracts of Inonotus obliquus (IOW) on the liver lymphocyte immune function in the Sprague-Dawley male rats treated with carbon tetrachloride ($CCl_4$) to induce liver damage. Rats were fed with each experimental diet and water for 4 weeks. We found that effects of IOW on interferon-gamma (IFN-$\gamma$), signal transducer and activator of transcription 1 (STAT1), phospho-signal transducer and activator of transcription 1 (pSTAT1) and GATA-binding protein 3 (GATA-3) were decrease in vivo. Interleukin-4 (IL-4), STAT6, pSTAT6 and T-box expressed in T-cells (T-bet) decreased significantly lower in $CCl_4$+IOW group than the $CCl_4$ group. Our data indicated that cytokine protein production were increased in $CCl_4$ group and $CCl_4$+IOW group. As a result of this study, we assume that IOW fed could regulate the immuno-modulating functions through regulate the cytokine production capacity activated by liver damage.

Objectives: The purpose of this study was to investigate the effects of Gardeniae Fructus Water Extract (GF) on the production of inflammatory mediators in RAW 264.7 cell treated with lipopolysaccharide (LPS). Methods: Gradeniae Fructus was extracted with distilled water (2,000 ml) for 2 hours. In order to evaluate cytotoxicity of GF, 3 - (4,5-dimethylthiazol-2-yl) - 2,5 - diphenyltetrazolium bromide (MTT) assay was performed. To investigate antiinflammatory effects, the concentration of nitric oxide (NO) was measured with No assay, calcium (Ca) was measured with Fluo-4 Ca assay, and cytokine was measured by Bio-Plex cytokine assay in RAW 264.7 cell. And when p-value is below 0.05, it is judged to have the significant difference statistically. Results: 1. GF did not show any cytotoxicity. 2. GF suppressed the production of NO and Ca at the concentration of 25, 50, 100 and $200{\mu}g/ml$. 3. GF suppressed the production of interleukin (IL)-$1{\beta}$, IL-10, IL-12p40, macrophage-colony stimulating factor (M-CSF), macrophage inflammatory protein (MIP)-$1{\beta}$ and keratinocyte chemoattractant(KC) at the concentration of 25, 50, 100 and $200{\mu}g/ml$. 4. GF suppressed the production of vascular endothelial growth factor (VEGF), granulocyte-colony stimulating factor (G-CSF) and monocyte cheomattractant protein (MCP)-1 at the concentration of 25, 50 and $100{\mu}g/ml$. 5. GF suppressed the production of granulocyte macrophage-colony stimulating factor (GM-CSF) and regulated on activation, normal T cell expressed and secreted (RANTES) at the concentration of 25 and $50{\mu}g/ml$. 6. GF suppressed the production of MIP-2 at the concentration of 50 and $100{\mu}g/ml$, and tumor necrosis factor (TNF)-${\alpha}$ at the concentration of 50 and $200{\mu}g/ml$. Conclusions: These results suggest that GF has anti-inflammatory effect and immuno-modulating activity.

Objectives: This study was designed to examine immuno-modulatory effects of Evodia Rutaecarpine by activating innate immune system and inhibiting inflammation. Methods: First, Cell cytotoxicity was examined with 4T1 breast carcinoma and TG-induced macrophage. To investigate activating innate immune system of Evodiamine Rutacarpine Extract (ERE) on macrophage, we tested tumor necrosis factor-alpha (TNF-α), interleukin-12 (IL-12), and interleukin-6 (IL-6). In addition, TNF-α and nitric oxide (NO) induced by lipopolysaccharide (LPS) were measured after treating with ERE to observe innate immune modulating effect of ERE on RAW 264.7 cell. Also, mitogen-activated protein kinase (MAPK) and nuclear factor κB (NF-κB) were examined by western blot analysis. Results: In cytotoxicity analysis, ERE significantly affected tumor cell growth above specific concentration. Also, ERE significantly affected macrophage growth above specific concetration. As compared with the control group, the production of TNF-α, IL-12 and IL-6 were increased in TG-induced macrophage. As compared with the control group, TNF-α and IL-6 were significantly up-regulated in RAW 264.7 cell. The expression of TNF-α and NO induced by LPS after treating ERE was significantly decreased compared with control group. In addition, We observed ERE inhibited the phosphorylation levels of p-extracellular signal-regulated kinase (p-ERK), p-Jun N-terminal kinase (p-JNK), and p-p38 in western blotting by treating ERE on RAW 264.7 cell. Conclusions: ERE seems to have considerable impact on the anti-cancer effect by activation of innate immune system and inflammation control.

Objectives : To clarify the possible effect of JS (Juglans sinensis), PCF (Psoralea corylifolia L.), and J+P(JS+PCF), we examined their influence on the development of pulmonary eosinophilic inflammation in the asthmatic murine model. Methods : All mice were immunized on two different days (21 days and 7 days before inhalational exposure) by intraperitonial injections of 0.2 ml alum-precipitated Ag containing 100 ${\mu}$g of OVA bound to 4 mg of aluminum hydroxide in PBS. Seven days after the second sensitization, mice were exposed to aerosolized ovalbumin for 30 minutes/day on 3 days/week for 8 weeks (at a flow rate of 250 L/min, 2.5% ovalbumin in normal saline) and, JS, PCF and J+P (200 mg/kg, 400 mg/kg) were orally administered 3 times per week for 8 weeks. Results : The suppressive effects of JS, PCF, and J+P were demonstrated by the accumulation of eosinophils into airways, with the reduction of eosinophils and lung leukocytes. These were correlated with the marked reduction of IL-4, IL-5, IL-13 levels in the BALF and serum. OVA-specific IgE levels were also decreased in serum and BAL from these mice. And also JS, PCF, and J+P decreased eosinophilic CCR3 and CD11b expression in lung tissue. Conclusions : These results indicate that JS, PCF, and J+P have deep inhibitory effects on airway inflammation and hyper-responsiveness in the asthmatic murine model. The suppression of IL-5, IgE, and eosinophilils and the increase of IFN-${\gamma}$ production in BALF seem to contribute to these effects. Specially, esosinophils and TNF-a in J+P combination group were significantly reduced in BALF and lung tissue. Hence, the results indicated that JS, PCF, and J+P could act as an immuno-modulator which possesses anti-inflammatory and anti-asthmatic property by modulating the imbalance between Th1 and Th2 cytokines.

This study was performed to compare the effects of immuno-modulating activities of Rhodiola sachalinensis A. Bor. fractionized by consecutive solvent separation. The Cytotoxicity of all fractionized extracts on human kidney cell (HEK293) was lower than crude extracts. Generally, the butanol and chloroform extracts showed less cytotoxicity on about 10.07% and 9.67% than the crude extracts. For human immune B and T cell growth, chloroform fraction showed the highest cell growth compared to the control. The secretion of cytokines (IL-6, $TNF-\alpha$) on human B and T cells were increased by adding chloroform extracts. Also, NK cell growth was significantly improved up to nearly 30% by adding the supernatant of B cell medium grown with the chloroform fraction. It was also found that chloroform fraction could yield higher nitric oxide production from macrophage than untreated control cells. Differentiation of HL-60 cells was increased up to 131.9% after treatment with chloroform fraction extracts, compared to the control. These results indicate that the chloroform fraction of R. sachalinensis have high immune activation activity than others fractions and the crude extracts, implying that this chloroform fractions could be used a new functional material.

목적: 본 연구진은 난자성숙 과정의 조절 기작을 규명하기 위하여 생쥐의 미성숙 난자와 성숙난자에서 차이 나게 발현하는 유전자의 목록을 얻은 바 있다. 이들 유전자 중에서 Bcl-2 homolog인 Diva 유전자가 난자에 특이적으로 발현함을 본 연구를 통해 규명하였는데 이러한 Diva의 기능을 밝혀내기 위하여 immunoprecipitation (IP)과 Mass Spectrometry (MS)를 이용하여 Diva와 결합하여 상호작용하는 단백질을 동정하고자 하였다. 연구방법: NIH/3T3 세포주에 Diva를 encoding하는 pCMV-FLAG-Diva를 24 시간 동안 과발현 시키고 대조군으로는 유전자 없는 pCMV-FLAG empty vector를 transfection 하였다. FLAG에 특이적인 항체로 IP하여 Diva와 결합하는 면역복합체를 형성하게 한 후 이를 12% SDS-polyacrylamide gel 상에서 전기 영동하였고 Coomassie Blue 염색을 통해 단백질 발현양상을 관찰하였다. 대조군에서는 관찰되지 않으면서 Diva 유전자가 발현하는 실험군에서만 확인되는 밴드를 오려내어 trypsin을 사용하여 in-gel digestion 한 후 MS 분석을 시행하였다. 모든 mass spectra는 4700 Proteomics Analyzer (Applied Biosystems, Framingham, MA)에 의해 positive reflector mode에서 얻어졌다. 이렇게 얻어진 단백질들은 MASCOT Peptide Mass Fingerprint software (Matrixscience, London)을 이용하여 NCBI nonredundant database를 찾아서 동정하였다. 결과: Diva를 과발현하는 세포주에서만 관찰되는 15개 밴드에 대한 MS/MS 분석 결과, Diva와 결합하는 단백질로서 actin과 그 외에 ${\alpha}$-actinin, tropomyosin, tropomodulin 3 등의 actin-binding 단백질을 동정하였다. Diva를 과발현하는 NIH/3T3 세포주에서 면역 복합체를 형성하는 actin과 tropomyosin이 실제 난소 조직에서도 Diva와 결합하는지 IP와 Western blot을 통해 확인한 결과, actin과 tropomyosin 모두 Diva와 결합함을 확인함으로써, Diva는 이 두 단백질과 난소에서 상호작용함을 알 수 있었다. 결론: 본 연구는 Diva와 결합하여 상호작용하는 단백질들이 cytoskeletal system의 actin filament와 관계 있음을 규명한 최초의 보고이다. Diva가 actin과 tropomyosin과 결합하는 것을 고려해볼때, 난자 특이적인 Diva는 아마도 난자성숙 동안에 cytoskeletal system 을 조절하는 역할을 할 것으로 사료된다.
