This study was carried out to investigate the comparison of immunomodualtory effects of water-extracted Ginseng Radix(GR), Pilose Asia-bell(PA), Astragali Radix(AR), Astractylodes Rhizoma alba(AA) and Dioscoreae Rhizoma (DR). The parameter examined to assess apparent immunomodulatory effect of the water-extracted GR, PA, AR, AA and DR included the regulation of Nitric oxide (NO), the expression of Th1/Th2 type cytokine, the change of B cell phenotype. The water-extracted GR, PA, AR, AA and DR inhibited NO production and iNOS protein expression in LPS stimulated RAW 264.7 macrophage cells. In the Th1 and Th2 cytokine expression, the water-extracted GR, PA, AR, AA and DR induced IL-2 and IFNr mRNA gene expression. Therefore, it seems that the water-extracted GR, PA, AR, AA and DR have a inducing effect of Th1 type cytokines. In the Flow cytometry analysis, the water-extracted GR, PA, AR, AA and DR did not change B cell phenotype (CD45R/B220). The water-extracted GR, PA, AR, AA and DR have a reducing effect of immune suppression cause by Methotrexate (MTX), an agent of immune suppression. These results suggest that the immunomodulatory effects of the water-extracted GR, PA, AR, AA and DR may be, in part, associated with the inducing IL-2 and IFNr mRNA gene expression in and regulation of NO production in macrophage cells.

목 적: 많은 연구에서 정신분열병에서 염증반응체계의 활성화와 사이토카인의 변화가 병태생리학적 및 원인적 역할을 하는 것으로 보고되어 왔으며, 여기에는 type 1 Thelper cell(Th1), type 2 T helper cell(Th2), type 3 T helper cell(Th3)의 조절 이상이 제시되고 있다. 본 연구에서는 정신분열병 환자에서 항정신병 약물 치료 전후로 Th1 사이토카인인 interleukin-12(IL-12), Th3 사이토카인인 transforming growth factor-${\beta}1$(TGF-${\beta}1$)의 혈장 농도를 측정하였다. 방 법: 23명의 정신분열병 환자군과 31명의 정상대조군에서 IL-12와 TGF-${\beta}1$ 농도를 측정하였고 정신분열병 환자군에서는 8주간 항정신병 약물로 치료 후 다시 IL-12와 TGF-${\beta}1$의 농도를 측정하였다. 또한 정신분열병 환자군에서 치료전과 8주간 치료 후, 2차례에 걸쳐 Brief psychiatric rating scale(BPRS)를 측정하였다. 결 과: 치료전 IL-12 농도와 TGF-${\beta}1$ 농도 모두 정상대조군보다 환자군에서 유의하게 높게 나타났다. 8주간의 치료 후 TGF-${\beta}1$ 농도는 유의하게 감소하여 정상대조군의 농도와 차이를 보이지 않게 된 반면, IL-12의 농도는 유의하지 않은 감소를 보였다. BPRS 점수의 변화 및 IL-12 및 TGF-${\beta}1$의 농도의 변화 사이에는 유의한 상관관계가 없었다. 결 론: 정신분열병의 병태생리학에 사이토카인의 이상이 관여할 수 있으며, TGF-${\beta}1$이 중요한 역할을 하는 것으로 생각된다.

Objectives : This study was performed to investigate immune regulatory effects of the pharmacopuncture with MOK on hyperthyroid rats. Methods : The experimental hyperthyroidism was prepared by the intraperitoneal injection of L-thyroxine(LT4, 0.5 mg/kg) once daily for 2 weeks in Sprague-Dawley(SD) rats. The pharmacopuncture with MOK extract(MOK pharmacopuncture) at doses of 0.3 or 3 mg/kg was injected on acupuncture points in the thyroid glands of hyperthyroid rats once a day for 2 weeks. Propylthiouracil(PTU, 10 mg/kg) as a reference group was subcutaneously injected into the dorsal neck. We measured the levels of $IFN-{\gamma}$ and IL-4 in the sera of rats using enzyme-linked immunosorbant assay(ELISA) and determined the expression of $IFN-{\gamma}$, IL-4, IL-10, and Foxp3 in spleen tissues by reverse transcriptase-polymerase chain reaction(RT-PCR). Results : The treatment of MOK pharmacopuncture in hyperthyroid rats significantly decreased the serum levels of Th1 cytokine, $IFN-{\gamma}$(p<0.01 for MOK 0.3 mg/kg, p<0.05 for MOK 3 mg/kg, and p<0.05 for PTU) and significantly increased the levels of Th2 cytokine, IL-4(p<0.05 for MOK 0.3 mg/kg, p<0.001 for MOK 3 mg/kg, and p<0.05 for PTU) compared to control group. Also, the MOK pharmacopuncture significantly increased IL-4 expression(p<0.05 for MOK 3 mg/kg, and p<0.05 for PTU), IL-10(p<0.05 for MOK 3 mg/kg, and p<0.01 for PTU), and Foxp3(p<0.01 for MOK 0.3 mg/kg, p<0.05 for MOK 3 mg/kg and p<0.01 for PTU) in spleen tissues of hyperthyroid rats compared to control group. Conclusions : Our results suggest that MOK pharmacopuncture can help to ameliorate the pathological progression of hyperthyroidism by regulation of the Th1/Th2 imbalance.

This research was performed in order to investigate the anti-inflammatory effects of Bupleuri Radix(BR) on the Immune response in vitro. Cellular proliferation and cytokine production were measured in mast cells or mouse B cells or CD4 Th cells. BR water extract inhibited the secretions of TNF-$\alpha$ and IL-6 in PMA/A23187 stimulated HMC-1 cells. It increased proliferation but did not affect the expressions of CD69 or CD23 in rIL-4/anti-CD40 activated S cells. BR reduced surface IgE expression and secreted IgE but increased the production of IL-4, IFN-$\gamma$ and IgG1 in the same cells. BR caused an increase in proliferation in anti-CD3/anti-CD28 stimulated CD4 Th cells but it did not affect the differentiation of Th1 or Th2 cells. However, IL-2 was increased in BR treated Th2 cells. Considering the above-mentioned results, BR can be applied to a broad range of anti-inflammatory reactions, but our data suggest that it will not be likely to exert any effects on type 1 allergic response.

We analyzed the effects of an Atopic Preventive Drink (APD) on the regulation of Th2 cytokines using RAW 264.7 macrophage cells. In the evaluation of nitric oxide (NO) production in cells, NO production levels were shown to be elevated only in the APD-treated group in a dose-dependent manner. In the lipopolysaccharide (LPS) with APD-treated group, NO production significantly decreased as APD concentration increased. Further, mRNA expression levels and protein concentrations of pro-inflammatory cytokines in cells were determined. Th2 stimulatory cytokine ($IL-1{\beta}$) and Th2 cytokine (IL-6 and IL-10) levels were significantly reduced in the LPS with APD-treated group compared to the only LPS-treated group. mRNA expression levels of inflammatory-related genes (COX-2 and iNOS) were significantly reduced in the LPS with APD-treated group compared to the only LPS-treated group. These results suggest that APD has an anti-atopic effect by reducing mRNA and proteins expressions of Th2 cytokines and inflammatory-related genes.

CD4+ T helper (Th) cells play a crucial role in the modulation of innate and adaptive immune responses through the differentiation of Th precursor cells into several subsets, including Th1, Th2, Th17, and regulatory T (Treg) cells. Effector Th and Treg cells are distinguished by the production of signature cytokines and are important for eliminating intracellular and extracellular pathogens and maintaining immune homeostasis. Stimulation of naive Th cells by T cell receptor and specific cytokines activates master transcription factors and induces lineage specification during the differentiation of Th cells. The master transcription factors directly activate the transcription of signature cytokine genes and also undergo post-translational modifications to fine-tune cytokine production and maintain immune balance through cross-regulation with each other. This review highlights the post-translational modifications of master transcription factors that control the differentiation of effector Th and Treg cells and provides additional insights on the immune regulation mediated by protein argininemodifying enzymes in effector Th cells.

BACKGROUND : Socheongryong-Tang(小靑龍湯, SCRT), a herbal medicine, has been widely used for the control of respiratory disease in Eastern countries. Recent years SCRT was known as anti-allergic agent. However, its therapeutic mechanisms, especially an inhibitory effect on inflammatory cell infiltration and airway remodeling in allergic asthma are unclear. METHODS : We investigated the effects of SCRT on levels of IL-4, and IFN-g using flow cytometric analysis and infiltration of inflammatory cells in bronchoalveolar lavage fluid(BALF) using cytospin methods in allergen-induced asthma. RESULTS : SCRT decreased levels of IL-4, a Th2-driven cytokine. But INF-g, a Th1-driven cytokine, was not changed. With SCRT treatment, infiltration of inflammatory cells showed reduced tendency. CONCLUSION : In conclusion, we demonstrated that regulation of Th1/Th2 imbalance may be one of mechanism contributed to reduction of inflammatory cell infiltration.

This study was undertaken to evaluate the immunomodulatory effect of dead nano-sized Lactobacillus plantarum (nLp) in RAW 264.7 cells and murine primary splenocytes. nLp is a dead, shrunken, processed form of L. plantarum nF1 isolated from kimchi (a traditional Korean fermented cabbage) and is less than 1 μm in size. It was found that nLp treatment stimulated nitric oxide (NO) production more in RAW 264.7 macrophages than pure live L. plantarum (pLp), and that the stimulatory properties were probably largely derived from its cell wall. In addition, nLp induced murine splenocyte proliferation more so than pLp; in particular, a high dose of nLp (1.0 × 10¹¹ CFU/ml) stimulated proliferation as much as lipopolysaccharide at 2 μg/ml. Moreover, according to our cytokine profile results in splenocytes, nLp treatment promoted Th1 (TNF-α, IL-12 p70) responses rather than Th2 (IL-4, IL-5) responses and also increased Th17 (IL-6, IL-17A) responses. Thus, nLp stimulated NO release in RAW 264.7 cells and induced splenocyte proliferation more so than pLp and stimulated Th1 and Th17 cytokine production. These findings suggested that dead nLp has potential use as a functional food ingredient to improve the immune response, and especially as a means of inducing Th1/Th17 immune responses.

Cordycepin was purified from a mushroom, Cordyceps militaris, and its effect on Th1 and Th2 cytokines was examined. The level of cytokine induction in mouse splenocytes was estimated after co-inoculation of purified cordycepin and LPS. When $5{\mu}g/ml$ of purified cordycepin was exposed to mouse splenocytes for 72 h, the level of a Th1 cytokine IL-12 increased by 2.9-fold. The addition of the purified cordycepin to splenocytes also increased the level of Th2 cytokines, IL-4 and IL-10, by 1.9- and 1.8-fold, respectively. Therefore, cordycepin increases the cytokine levels and may contribute to the up-regulation of cellular and humoral immunity.
