Culture supernatants of splenocytes from C57BL/6 mice were exposed to 0.3, 1.0, and 3.0 ${\mu}g/ml$ cordycepin plus 3.0 ${\mu}g/ml$ lipopolysaccharide (LPS) to investigate the effects of cordycepin (3'-deoxyadenosine) on the production of inflammatory cytokines. Coadministration of 3.0 ${\mu}g/ml$ cordycepin with LPS in cultured murine spleen cells significantly diminished expression of the inflammatory cytokines tumor necrosis factor-${\alpha}$ and interleukin-6 (IL-6) in a time-dependent manner. Expression of the inflammatory cytokine IL-17A was substantially downregulated in a timeand concentration-dependent manner at all cordycepin concentrations. These findings suggest that cordycepin downregulates the immediate hypersensitivity reaction stimulated by LPS.

Fresh Rehmanniae radix is known as a traditional medicine with anti-inflammatory and antioxidant activities. However, whether Rehmanniae radix attenuates autoimmune inflammation in lupus models characterized by T cell-dependent autoimmune disease including overproduction of proinflammatory cytokines, loss of T cell tolerance, and B cell hyperactivity remains unclear. We investigated the effect of fresh Rehmanniae radix methanol extracts (RGMeOH) on the in vitro overproduction of proinflammatory cytokines by immune cells from pristaneinduced lupus BALB/c mice. These results showed that RGMeOH remarkably attenuated Con A-increased overproduction of proinflammatory cytokines, such as IL-2, IFN-${\gamma}$, IL-6 and IL-10 by splenocytes from pristaneinduced lupus mice. RGMeOH greatly reduced LPS-induced production of TNF-${\alpha}$ by splenic macrophages from pristane-induced lupus mice, while significantly enhanced LPS-induced production of IL-10 but did not alter IL-6 by splenic macrophages and splenocytes. These findings suggest that RGMeOH may ameliorate lupus systemic inflammatory autoimmunity via down-regulation of TNF-${\alpha}$ and T cell-dependent cytokine production.

Hominis placenta (HP) has been used as an agent for promoting physiological function in traditional asian medicine. The present study was peformed to investigate whether HP acupuncture treatment in an experimental tumor mice model inhibit tumor growth through immunomodulatory effects. Mice were inoculated subcutaneously with colon26-L5 cells on the back. Three days after tumor inoculation, HP herbal acupuncture treatment was conducted on BL18 acupoint every other day for three weeks. HP Herbal acupuncture treatment significantly suppressed the primary tumor growth and prolonged survival rate. To evaluate immunomodulatory effect of HP acupuncture, splenocytes proliferation assay, fluorescence-activated cell sorting (FACS) and ELISA for IFN- ${\gamma}$, and IL-4 cytokine level. HP herbal acupuncture enhanced the mitogenic activity of Balb/c whole splenocytes induced by various mitogenic stimuli and increased immune cell population such as T cell, B cell, Th cell, Tc cell and Macrophages. HP herbal acupuncture caused a marked increase of production of Th1 cytokine (IFN- ${\gamma}$ ,) and decrease of production of Th2 cytokine (IL-4). These results indicated that HP herbal acupuncture suppresses tumor growth through a mechanism leading to a Th1 dominant immune state.

Reactive oxygen species play a role in signal transduction and in many human diseases. B-cell activating factor (BAFF) plays a role for mature B cell generation and maintenance and for the incidence of autoimmune diseases. We previously reported that BAFF expression was induced by ROS. In this study, we investigated whether ROS-induced BAFF expression was affected by toll-like receptor (TLR) 4 or myeloid differentiation primary response gene (MyD) 88. BAFF expression was increased by serum deprivation that is an experimental modification to produce ROS. In contrast, TLR4 and MyD88 were decreased by serum deprivation. Although ROS production was decreased in TLR4-nonfunctional or MyD88-deficient splenocytes as compared to that in control mice, serum deprivation increased ROS production and augmented BAFF expression in both cells. $50{\mu}M\;H_2O_2$ also increased BAFF expression in TLR4-deficient or MyD88-deficient splenocytes. Collectively, results show that BAFF expression may be mediated by TLR4 or MyD88-independent manner and TLR4 or MyD88 may not be required in BAFF expression.

In this study, we evaluated the immune-enhancing activity of kimchi-derived Lactobacillus plantarum 200655 on immune suppression by cyclophosphamide (CP) in ICR mice. Animals were fed distilled water or 1×10⁹ colony-forming unit/kg B.W. 200655 or Lactobacillus rhamnosus GG as a positive control for 14 days. An in vivo model of immunosuppression was induced using CP 150 and 100 mg/kg B.W. at 7 and 10 days, respectively. Body weight, spleen index, spleen weight, and gene expression were measured to estimate the immune-enhancing effects. The dead 200655 (D-200655) group showed an increased spleen weight compared to the sham control (SC) group. Similarly, the spleen index was significantly higher than that in the CP-treated group. The live 200655 (L-200655) group showed an increased mRNA expression of tumor necrosis factor-alpha (TNF-α) and interleukin (IL)-6 in splenocytes. Also, the iNOS and COX-2 mRNA expression was upregulated in the L-200655 group compared to the CP-only (SC) group. The phosphorylation of ERK and MAPK was also upmodulated in the L-200655 group. These results indicate that L. plantarum 200655 ameliorated CP-induced immune suppression, suggesting that L. plantarum 200655 may have the potential to enhance the immune system.

OVA를 항원으로 한 식품알레르기 마우스 모델을 이용하여 감태 물 추출물의 알레르기 억제 효과를 확인하였다. 먼저, OVA로 면역한 마우스의 비장세포에 감태 물 추출물을 첨가하여 배양한 후, 배양 상층액의 IgE antibody와 IL-4 및 IFN-$\gamma$ cytokine 분비량을 측정하였다. 그 결과, $10\sim100{\mu}g$/mL 농도의 감태 물 추출물 첨가로 비장세포의 IgE 분비량이 농도 의존적으로 감소하였고, IL-4 및 IFN-$\gamma$ 분비량도 감태 물 추출물 첨가 농도가 증가할수록 감소하였다. 감태의 알레르기 억제능을 in vivo 실험을 통해 확인하기 위해 OVA로 알레르기를 유발한 마우스에 감태 물 추출물을 복강주사 한 후 혈청과 비장세포의 IgE 분비능을 확인하였다. 혈청의 항체 분비량 측정 결과, 1, 5 및 10 mg/kg BW 농도의 감태 물 추출물 투여군이 PBS 투여군에 비해 유의적으로 낮은 OVA-specific IgE 분비량을 보였다. 반면, IgG1과 IgG2a 분비량은 추출물 투여군과 PBS 투여군 사이에 유의적인 차이를 보이지 않았다. 또한 비장세포의 IgE 분비량이 5 및 10 mg/kg BW 농도의 감태 물 추출물의 복강주사에 의해 감소함을 확인하였다. 이상의 결과를 통해 감태 물추출물이 IgE 분비량의 유의적인 감소 효과를 통해 식품알레르기 반응을 효과적으로 억제할 수 있을 것으로 사료된다.

Background: Aerobic training can be defined as any physical exercise that increases the heart rate and enhances the body's intake of oxygen long enough to benefit the condition of body. Running, cycling, and swimming are examples of aerobic activities. This type of exercise optimises immune functions. Recently several experimental findings suggested that the regular swimming training increase immune response, but there have been very few reports which compare warm water exercise with cold water exercise in spleen lymphocytes. Methods: This study was designed to examine the effects of regular swimming training on Index, the number of lymphocytes, proliferative activity and production of reactive oxygen species (ROS) by splenocytes in BALB/c mice. Thirty six mice (6 week old) were performed 10 weeks of regular swimming training and they were divided into 6 groups according to the regular swimming training (CRG: control resting group, CEG: control exercise group, WRG: warm water trained resting group, WEG: warm water trained exercise group, CORG: cold water trained resting group, COEG: cold water exercise group). Analytical items were weight change, spleen index, the number of lymphocytes, proliferative activity and production of ROS. All data were expressed as mean and standard deviation by using SPSS package program (ver. 10.0). Results: The swimming training significantly decreased body weight, and increased spleen index, the number of lymphocytes and proliferative activity in the presence or absence of Con A and LPS added conditions. For the WRG and CORG, the quantity of ROS from splenocytes was higher than CRG, whereas, ROS by spleen lymphocytes was lower following 90 min acute exercise stress. Conclusion: These results suggested that the swimming training not only increases the number of lymphocytes but also increases proliferative activity by splenocytes in vitro.
