Objective : Soybeans of Canavalia gladiata(CG) and root of Arctium lappa(AL) have been reported to have anti-inflammatory, antioxidant effect. However, the immunoregulatory mechanisms of its combinational prescription remain a matter of considerable debate. In the current study, we investigated whether CG and AL and its combinational prescription(CG+AL) regulate immune system using chronic immobilization-stress mouse model. Methods : C57BL/6J mice fixed for 2 hours into immobilization tube after CG, AL, CG+AL oral administration after 2 hours daily for 21 days. After every experiment has ended the C57BL/6J mice were sacrificed on 22 days. The production of Serotonin and Cortisol, lgA were observed by ELISA method, The proportion of immune cells such as T/B cell and macrophage, NK cell were measured by FACS. Then, Real-time PCR was performed to measure the mRNA expression of Inflammatory cytokines(IL-1beta, IL-6, TNF-a) and T cell activation cytokines(IL-2, IL-10, IFN-gamma, IL-12p35 / p40). Result : When chronic immobilization-stress mouse model were treated with CG+AL(1:4), the expression of mRNA were significantly decreased at the Inflammatory cytokines(IL-1beta, IL-6, TNF-a). While, the levels of mRNA were significantly increased at immune T cell activation cytokines. Additionally, CG+AL(1:4) combinational prescription group enhanced immune cells such as T/B cell and macrophage, NK cell. Furthermore, the Immuno-fluorescence result of brain tissue can confirm that CG+AL(1:4) group significantly increased the BDNF expression. Conclusion : These result suggest that CG+AL(1:4) combinational prescription has Immune System enhancement via stress-mediated immunocyte.

Tuna cooking juice concentrate (TCJC) is by-produced during the canning processing of skipjack tuna Katsuwonus pelamis and it is well known that TCJC contains various nutritional components. Therefore, the immuno-stimulating activity of TCJC was investigated using macrophage RAW 264.7 cell line and the spleen cell isolated from BALB/c mice. The TCJC increased the production of IL-6, TNF-${\alpha}$, and IL-$1{\beta}$ in a dose-dependent manner compared to the control in RAW 264.7 cells without any toxicity. In particular, the production of TNF-${\alpha}$ was increased over 300-fold. The production of both Th1 cytokine (such as IFN-${\gamma}$, TNF-${\alpha}$, IL-2, and IL-12) and Th2 cytokine (IL-4, IL-6, IL-10) was also increased by TCJC treatment in splenocytes. Moreover, the TCJC increased the splenocyte proliferation in a concentration-dependent manner compared to control. These results indicate that TCJC may enhance immune function by promoting various cytokine production.

본 연구에서는 오리나무유래 HST의 T 세포 비활성화 효능을 확인하고 그 기전을 탐색하여 새로운 항아토피 천연소재로의 개발 가능성을 제시하고자 하였다. HST는 T 세포 mitogen으로서 anti-CD3 mAb가 처리 된 마우스 비장에서 Th 사이토카인(IL-2, IFN-${\gamma}$, IL-4, IL-5, IL-10)의 발현을 효과적으로 억제하였으며, T 세포 early activation marker인 CD25 유전자 발현이 INCA-6에서 매우 효과적으로 억제되는 것으로 보아, NFAT inactivator-유사 NFAT 탈인산화 억제 기전을 가지는 것으로 예측되었다. 또한 세포주기조절 단백질인 p21과 p27의 유전자도 HST에 의해 upregulation이 되어 효과적인 T 세포 증식 및 분화를 억제할 것으로 생각되었다. 이러한 세포주기조절 효과는 AD를 악화시키는 세균인 S. aureus 성장억제 실험에서 확인되어 향후 항박테리아 효능을 갖는 우수한 항아토피피부염 천연소재로서 HST의 활용 가치가 높을 것으로 판단된다.

Orientia tsutsugamushi, a gram-negative bacterium, causes severe acute febrile illness in humans. Despite this danger, the route of infection, infectivity, and protective mechanisms of the host's immune response to O. tsutsugamushi are unclear. Dendritic cells (DCs) are one of the most important cell types in bridging the innate and adaptive immune responses. In this study, we observed that O. tsutsugamushi infects and replicates in monocyte-derived DCs (MODCs). During infection and replication, the expressions of the cytokines IL-12 and TNF-${\alpha}$, as well as the co-stimulatory molecules CD80, CD83, CD86, and CD40, were increased in MODCs. When O. tsutsugamushi-treated MODCs were co-cultured with autologous $CD4^+$ T cells, they enhanced production of IFN-${\gamma}$, a major Th1 cytokine. Collectively, our results show that O. tsutsugamushi can replicate in MODCs and can simultaneously induce MODC maturation and increase proinflammatory cytokine levels in MODCs that subsequently activate $CD4^+$ T cells.

Objectives Previous studies have found out that Forsythiae Fructus (FF) extracts have anti-atopic activities by in vitro experiment. In order to understand more about FF extracts' benefit, we subdivided FF extracts depending on systematic fractionation method by using Methylene chloride (MC), Ethyl acetate (EtOAc), n-BuOH and n-hexane (n-Hx). This study is designed to examine the effect of FF fractions on the PMA- ionomycin-induced activation of RBL-2H3 mast cell lines in vitro and on the DNCB-induced activation of NC/Nga mice in vivo. Methods For this study, we examined IL-4, IL-13 production by ELISA analysis, IL-4, IL-13, IL-31, IL-31RA and TNF-${\alpha}$ mRNA expression by real-time PCR and manifestations of AP-1 and MAPKs transcription factors by western blotting in vitro. Through in vitro experiment, we selected FF n-BuOH fraction that seems the best effective in atopic dermatitis then induced it on NC/Nga mice by DNCB. We measured mice's WBC, eosinophil and neutrophil in heart blood, IL-4, IL-5, IFN-${\gamma}$ in the spleenocyte culture supernatant, the absolute cell numbers of CD4+, CD8+, B220+CD23+, CD3+CD69+ and Gr-1+CD11b+ in the PBMCs, ALN and dorsal skin, IL-5, IL-13, IL-31, IL-31RA in the dorsal skin by real-time PCR and the distribution of immune cells by H&E on dorsal skin and ANL and toluidine blue staining on dorsal skin. Results FF n-BuOH fraction suppressed IL-4, IL-13 production and mRNA expression of IL-4, IL-13, IL-31, IL-31RA and TNF-${\alpha}$. Results from the western blot analysis showed that FF n-BuOH fraction reduced the activation of the mast cell specific transduction factors involved in AP-1 by suppressing JNK and ERK phosphorylation. In the gross, atopic dermatitis induced by DNCB in NC/Nga mice were improved by oral administration of FF n-BuOH fraction. Oral FF n-BuOH fraction also decreased the level of IgE in mice's serum and the level of IL-4 and IL-5 in the spleenocyte culture supernatant, cell numbers of CD8+, B220+CD23+ in the PBMCs, CD4+ in the ALN and CD4+, Gr-1+CD11b+ in the dorsal skin and suppressed mRNA expression of IL-5, IL-13, IL-31, IL-31RA in the dorsal skin. Histological examination showed that infiltration levels of immune cells in atopic dermatitis induced NC/Nga mice were improved by FF n-BuOH fraction. Conclusions FF n-BuOH fraction can reduce pruritus by suppressing IL-31, IL-31RA secretion and modulate molecular mediators and immune cells associated with atopic dermatitis induced in NC/Nga mice which may have played a significant role in recovering atopic dermatitis symptoms.

After the LH-AS treatment on synovial cells, there were no significant change in 1, 10, 50 and $100{\mu}g/m{\ell}$ whereas there was significant change in 200 and $400{\mu}g/m{\ell}$ in cytotoxicity. 2. IL-6, IL-$1{\beta}$, TNF-${\alpha}$ gene expression of synovial cells and the secretion amount of IL-6 and IL-$1{\beta}$ are significantly inhibited in treatment group with LH-AS. 3. The proliferation of synovial cells was significantly inhibited in treatment group with rIL-6, LH-AS 200 and rIL-6, $100{\mu}g/m{\ell}$. 4. After the DBA/1J mice with collagen II-induced arthritis were treated by LH-AS, the incidence of arthritis, hind paw edema, the index of arthritis and DTH were significantly inhibited. 5. After the DBA/1J mice with collagen II-induced arthritis were treated by LH-AS, splenetic weight was significantly increased and the number of leukocyte was significantly decreased. But there was no significant change in the number of platelet. 6. After the DBA/1J mice with collagen II-induced arthritis were treated by LH-AS, the number of $CD4^+$, $CD8^+$ activated cells and the surface-receptor expression were significantly increased whereas the number of $CD19^+$ activated cells and the surface-receptor expression were decreased. 7. After the DBA/1J mice with collagen II-induced arthritis were treated by LH-AS, total protein, LDH were significantly decreased, but there was no significant change in creatinine. 8. After the normal splenetic cells of BALB/C mice were treated by LH-AS and cultured, it was observed that the adherent cells were morphologically activated and IL-12 and IFN-${\gamma}$ gene expression were increased. 9. After the normal splenetic cells of BALB/C mice were treated by LH-AS and cultured, the number of $CD4^+$, $CD8^+$, $CD19^+$ activated cells and surface-receptor expression were inhibited when being compared with the control group. Taking all these observations into account, LH-AS injection is considered to be effective in treating arthritis and put to practical use in future arthritis clinic.

The present study was carried out to investigate the effects of dietary antioxidants on pro-inflammatory cytokines, heat shock protein (HSP) and antioxidant status in broiler chicks under summer conditions. A total of 162, 3-d-old broiler chicks were randomly assigned to a basal diet (CON) and the basal diet supplemented with vitamin C (200 mg/kg diet, VCD) or vitamin E (100 mg/kg, VED) until 35 day of age. All birds were exposed to summer diurnal heat stress at average daily fluctuations of temperature between $32^{\circ}C$ to $34^{\circ}C$ at day to $27^{\circ}C$ to $29^{\circ}C$ at night for the entire feeding periods. There was no significant difference in body weight, feed to gain ratio and the relative organ weight except the thymus in response to dietary vitamin C or E supplementation. However, the mRNA expression of interleukin (IL)-$1{\beta}$, IL-6, interferon (IFN)-${\gamma}$, Toll like receptor (TLR)-4 and HSP70 in the liver of birds fed diet containing vitamin C significantly (p<0.05) decreased compared with those in birds fed basal diet. Dietary vitamin E also showed a significant (p<0.05) decrease in the mRNA expression of IL-6 and HSP70 compared with a basal diet. Total antioxidant status (TAS) in serum of birds fed vitamin C supplemented diet was significantly (p<0.05) higher with than that in birds a basal diet. Lipid peroxidation in serum and liver resulted in a significant (p<0.05) decrease in response to dietary vitamin C or E supplementation. In conclusion, dietary supplementation with antioxidant vitamins, especially vitamin C resulted in a significant decrease in the mRNA expression of pro-inflammatory cytokines and HSP70, and higher antioxidant parameters than that of birds on the basal diet under summer conditions.
