Objective: In this study, the immunomodulatory activity of a mixture of wild Panax ginseng and red-mold rice extracts (MPR) on RAW 264.7 macrophage cells in the presence and absence of methotrexate (MTX), an anti-cancer drug, was investigated. Methods and Results: In the cell viability, MPR showed a significant cell proliferation and inhibited cell regression by red-mold rice (RMR) alone or MTX alone. MPR induced moderate increase in nitric oxide (NO) production. NO production and inducible nitric oxide synthase (iNOS) mRNA expression by LPS decreased after MPR treatment. In addition, MPR slightly induced COX-2 mRNA expression, but it did not affect the expression of COX-2 mRNA by LPS treatment. In RT-PCR analyses, MPR induced IL-$1{\alpha}$, IL-$1{\beta}$, IL-6, and TNF-$\alpha$ mRNA expression, but had no effect on IL-10 and TGF-$\beta$, regardless of MTX treatment. Furthermore, MPR did not interfere with the cytotoxicity of MTX against MCF-7 human breast carcinoma cells. Conclusions: MPR is efficacious in protecting against MTX-induced cell regression as a result of macrophage activation, resulting in induction of cytokine expression, implying that MPR could be considered an adjuvant in MTX-chemotherapy.

Phellinus linteus (PL), one of the immune-regulatory substances, is recognized to play the role in the metabolic process on inflammation and immunity. It has been traditionally used in the oriental medicine to treat inflammatory related disease. The purpose of this study was to evaluate the effects of water extracts of PL on the mesenteric lymph node lymphocytes immune function in the ICR male mice. Control mice received vehicle only. The PL treated mice were administered the respective extract by oral gavages for 4 weeks. IgE concentrations in serum and MLN lymphocytes were significantly lower in PL treated mice than in control mice. PL increased the proportion of $CD4^+\;and\;CD8^+$ T cells in MLN lymphocytes. PL significantly decreased Th2 cytokine concentrations and mRNA expression levels in cytokine secretions. Therefore, water extracts of PL modulate inflammatory parameters through regulation of immunoglobulin production resulting from decreased Th2 cytokine secretion and mRNA expression levels and reduce pro-inflammatory cytokine secretion and mRNA expression in MLN lymphocytes.

The present study was conducted to evaluate the immunomodulatory effects of Dangguijakyak-san(당귀작약산). We investigated the effects of cell proliferation in mouse spleen cell and RAW 264.7 macrophages cells. Dangguijakyak-san enhanced mitogenic activity in the dose-response manner in mouse spleen cells and RAW 264.7 macrophages cells. In nitric oxide (NO) synthesis and iNOS mRNA expression by Dangguijakyak-san, Dangguijakyaksan alone had an effect on NO synthesis and iNOS mRNA expression in RAW 264.7 cells. NO production and iNOS mRNA expression which is excessively induced by LPS decreased after treatment of Dangguijakyak-san. The expressions of cytokine gene by Dangguijakyak-san investigated using reverse transcription polymerase chain reaction (RT-PCR). In RT-PCR, IL-1α, IL-1β and IL-6 mRNA expressions induced in Dangguijakyak-san-treated RAW 264.7 cells. These data indicate that 1) Dangguijakyak-san can modulate various immune response and 2) the immunomodulatory effects of Dangguijakyak-san may be, in part, associated with the regulation of NO synthesis, the expressions of these cytokine as well as the mitogenic effect on spleen cells and macrophages cells.

To elucidate the mechanism of age-related development in FGS/NgaKIST mice with spontaneous glomerulosclerotic lesion, we examined expression and localization of various cytokine mRNA in the kidney in the progression of diseases. This mouse model is the first to develop spontanously occuring glomerosclerotic lesion in the kidney. In this study, we detected the up-regulation of local cytokine genes such as IL-1$\beta$, IL-2, IL-6, IL-10, TNF-$\alpha$, TGF-$\beta$, and IFN- $\gamma$ in the kidneys. In RT-PCR and Southern blot analysis, we detected gradual expressions of cytokine mRNA of IL-1$\beta$, IL-2, IL-6, IFN- $\gamma$, and TNF $\alpha$ mRNA during the course of disease. Other cytokines including IL -10 and TGF -$\beta$ were found to be appeared the slightly expressed level at 3 to 12 weeks before onset of inflammatory lesion but they are highly expressed at the end-stage of the disease accompaning high proteinurea and wasting. In situ RT-PCR, each cytokine mRNA were specifically localized in a variety of cells including mesangial, endothelial, parietal epithelial, tubular epithelial, arterial muscle cell, and infiltrated inflammatory cells. In addition, TNF - $\alpha$was detected moderately in the visceral and parietal epithelial cell, but weakly in endothelial and mesangial cells, whereas IL-1 $\beta$ and IL -6 were strong in mesangial regions. IL-6 and TNF- $\alpha$ was highly localized in the damaged proximal and collecting tubules. Especially, TGF -$\beta$ mRNA was highly found in mesangial cells within glomerulus and interstitium during the end-stage of this disease.. These results indicate that pro inflammatory cytokines such as IL-1 $\beta$, IL-2, IL-6, and TNF- $\alpha$ were gradually expressed from the early stage of this disease to the end-stage, and that IL-10 and TGF-$\beta$ may be important in the accumulation of extracellular matrix(ECM) within glomerulus and periglomerular fibrosis in the progression of this disease as well as tissue destruction in end-stage of this disease.

연구배경: 산화질소(${\cdot}NO$)는 여러 세포에서 산화질소 합성효소(NOS)에 의해서 생산되며 다양한 병태생리과정에 관여한다. 여러 cytokine들이 iNOS의 발현을 촉진시키고 산화질소 생산을 증가시킴으로써 염증반응을 증폭시키고 세포와 조직손상을 초래한다고 알려진 바, 과산화수소($H_2O_2$)가 세포내 NOS의 발현과 산화질소형성에 미치는 영향을 알아보고자 하였다. 방법: 마우스 대식세포주 RAW264.7에 여러 가지 cytokine과 세균 내독소 (LPS)로 자극을 준 세포군 이에 더하여 $H_2O_2$, NOS 억제제 (L-NAME) 및 항산화제 (catalase)등을 사용하여 세포를 자극한 후 생성된 산화질소 산화물의 농도를 측정하고 Northern analysis로 iNOS mRNA의 발현정도를 보아 다음과 같은 성적을 얻었다. 결과: Cytokine과 LPS 자극군에서 대조군보다 ${\cdot}NO$ 생산이 높았고, 이 자극군에 $H_2O_2$를 추가로 자극하였을 때 ${\cdot}NO$생산이 2 배 이상 유의하게 높았다. Cytokine 자극군에서 $H_2O_2$의 자극 농도에 따른 ${\cdot}NO$생산은 $H_2O_2$의 농도가 증가할수록 유의하게 증가하였다. LPS와 IFN-$\gamma$ 자극군에서 L-NAME을 같이 자극시에 ${\cdot}NO$의 양은 L-NAME의 농도증가에 따라 유의하게 감소하였고, Cytokine 및 $H_2O_2$자극군에서도 추가로 자극한 L-NAME 의 농도증가에 따라 ${\cdot}NO$의 양은 유의하게 감소하였다. Cytokine과 $H_2O_2$ 자극균에 catalase를 같이 자극 하였을 때 ${\cdot}NO$의 양은 유의하게 감소했고, Mercaptoethanol과 phenanthroline을 전처치하고 LPS와 IFN-$\gamma$ 및 $H_2O_2$로 자극한 군에서 이들의 전처치한 농도가 높을수록 ${\cdot}NO$의 양은 유의하게 Cytokine자극군과 IFN-$\gamma$, LPS 자극군에 $H_2O_2$를 추가 자극 후 Northern analysis 결과 $H_2O_2$는 iNOS mRNA 발현을 현저히 증가시켰다. 결론: 이상의 결과로 과산화수소가 cytokine과 내독소 등으로 자극된 마우스 대식세포에서 산화질소생산에 유의한 증폭효과를 나타냈고, iNOS mRNA 의 발현도 증가시켰음을 확인할 수 있었다.

대식세포는 IL-1, IL-6, $TNF-{\alpha},\;IFN-{\gamma}$의 중요한 근원이고, 전염성의 병원체와 종양 세포에 대해 저항하는 주요한 effector 세포이다. 이것은 cytokine signal에 의해 세포파괴가 되도록 활성화 된다. 이번 연구에서 우리는 산더덕의 물 추출물이 cytokine, nitric oxide와 같은 effector 분자를 유도하기 위해 대식세포를 활성화하는지를 알아보기 위하여 실험하였다. 산더덕 추출물에 의한 대식세포의 NO 생성은 농도 의존적이고, 시간 의존적이었다. iNOS는 시간이 지날수록 발현이 유도되었다. 산더덕 추출물에 의한 IL-1과 IL-6 mRNA 유도는 시간 의존적으로 증가 되었고, 처리 후 24시간에 최고점에 도달하였다. 이것은 활성화된 대식세포가 종양세포를 죽일 수 있음을 말한다. $TNF-{\alpha}\;mRNA$의 양은 시간이 지나도 일정하였고, $IFN-{\gamma}\;mRNA$의 양은 산더덕 추출물의 처리 1시간 후에 빠르게 강화되었다. 이러한 결과로부터 산더덕은 효과적인 면역조절자이고 대식세포의 항종양활성을 강화함을 알 수 있다.

Artemisiae Asiaticae Herba (AAH) has been used to remedy of symptoms such as bleeding, dysmenorrhea, eczema and itchy skin in Oriental Medicine. In this study, we investigated the protective effect of AAH on allergic response. The effect of AAH was analyzed by ELISA and RT-PCR in RBL-2H3 cells. We investigated cell viability, ${\beta}$-hexosaminidase and histamine as markers of degranulation, production of IL-4 and TNF-${\alpha}$, and gene expression of HDC2, cytokines and $Fc{\varepsilon}RI$ ${\alpha}{\beta}{\gamma}$ subunit. We found that AAH suppressed ${\beta}$-hexosaminidase and histamine release, the production of IL-4 and TNF-${\alpha}$ in RBL-2H3 by the anti-DNP IgE plus DNP-HSA stimulation. AAH also significantly decreased cytokine mRNA expressions, such as IL-$1{\beta}$, IL-2, IL-3, IL-4, IL-5, IL-6, IL-12, IL-13, TNF-${\alpha}$, and GM-CSF, and increased cytokine mRNA expressions of IL-10 in RBL-2H3. In addition, AAH suppressed mRNA expression of $Fc{\varepsilon}RI$ ${\alpha}{\beta}{\gamma}$ subunit on cell surface. Our results indicate that AAH protects against allergic response and exerts an anti-inflammatory effect through the inhibition of degranulation and production of cytokines and expression of $Fc{\varepsilon}RI$ ${\alpha}{\beta}{\gamma}$ subunit.
