  • Plantago asiatica L., observed frequently in East Asia, is a known herb used in traditional medical remedies several studies report that P. asiatica L has anti-inflammatory and antioxidant effects. To determine the production of cytokines (IL-2, $IFN-{\gamma}$, and $TNF-{\alpha}$) induced by lipopolysaccharide (LPS) and non-LPS-stimulated macrophages, an ELISA assay was conducted using cytokine kits. Mice splenocytes were cultured for 48 h with various concentrations of P. asiatica L. (5, 10, 50, 100, 250, 500, and $1,000{\mu}g/mL$) or with mitogens (ConA or LPS). P. asiatica L. increased the proliferation of mice splenocytes, especially under the condition of its concentration ranging from 250 to $1,000{\mu}g/mL$. In addition, Plantago asiatica L. notably induced cytokine production of (IL-2, $IFN-{\gamma}$, and $TNF-{\alpha}$) at its concentration of $250{\sim}500{\mu}g/mL$. These results suggest that supplementation with P. asiatica L. water extracts may play a potential role in enhancing immune function by mediating splenocyte proliferation and cytokine production through its anti-inflammatory activit.

  • Objectives: Herbal acupuncture has been administered with Liriopis Tuber extract on the point of BL 13 (Pyesu) to treat bronchial asthma and a certain degree of clinical benefits have been observed but lacking scientific substantiation. Methods: The present report describes on Th1 cytokine (Interleukin-2, Interferon-gamma), Th2 cytokine, (Interleukin-4, Interleukin-5), and IL-12 in bronchoalveolar lavage fluid (ELISA). Five groups were devised to study the effects of herbal acupuncture with Liriopis Tuber extract at BL 13 (Pyesu) for airway inflammation in the mouse model with bronchial asthma. Results shows that herbal acupuncture with Liriopis Tuber extract at BL 13 increased Th1 cytokine (Interleukin-2) in allergic sensitization and allergic challenge, and decreased Th2 cytokine (Interleukin-2, Interleukin-5) in allergic sensitization.

  • The nucleotide-oligomerization domain (NOD) proteins are members of the NOD-like receptor (NLR) family, which are intracellular and cytoplasmic receptors. We analyzed the role of NODs for cytokine production by macrophages infected with intracellular pathogen M. leprae, the causative agent of leprosy. Production of pro-inflammatory cytokines such as IL-$1{\beta}$ and TNF-${\alpha}$ was inhibited in the presence of cytochalasin D, an agent blocking phagocytosis, suggesting that intracellular signaling was, partially, required for macrophage activation to M. leprae infection. Next, we investigated the role of NOD1 and NOD2 proteins on NF-${\kappa}B$ activation and cytokine expression. Treatment with M. leprae significantly increased NF-${\kappa}B$ activation and expression of TNF-${\alpha}$ and IL-$1{\beta}$ in NOD1- and NOD2-transfected cells. Interestingly, their activation and expression were inhibited by cytochalasin D, suggesting that stimulation of NOD proteins may be associated with the enhancement of cytokine production in host to M. leprae.

  • Objectives: The purpose of this study was to investigate effects of Red Ginseng-Ejung-tang Water Extract (ER) on cytokine production in RAW 264.7 mouse macrophages stimulated by lipopolysaccharide (LPS). Methods: Levels of various cytokines such as interleukin (IL)-6, IL-10, IL-2, IL-12p70, vascular endothelial growth factor (VEGF), monocyte chemoattractant protein (MCP)-1, macrophage inflammatory protein (MIP)-2, keratinocyte-derived chemokine (KC), tumor necrosis factor (TNF)-alpha, granulocyte macrophage colony-stimulating factor (GM-CSF) were measured by high-throughput multiplex bead array cytokine assay based on xMAP (multi-analyte profiling beads) technology. Results: ER significantly decreased levels of IL-6, IL-10, IL-2, IL-12p70, VEGF, and MCP-1 for 24 hrs incubation at the concentrations of 25, 50, and $100{\mu}g/mL$ in LPS-induced RAW 264.7 cells (P < 0.05). But ER did not exert significant effects on production of MIP-2, KC, TNF-${\alpha}$, and GM-CSF in LPS-induced RAW 264.7 cells. Conclusions: These results suggest that ER has an anti-inflammatory property related with its inhibition of cytokine production in LPS-induced macrophages.

  • Forty seven amylolytic Bifidobacterium strains were isolated on starch-containing agar medium from the faecal samples of the various age groups of Korean. From these amyloytic Bifidobacterium spp., two strains of KFRI 1535, identified temporarily as Bifidobacterium longum, and KFRI 1550, identified as Bifidobacterium breve, showed great macrophage-stimulating activity for the production of tumor necrosis factor-$\alpha$ and inteleukin-6. As the cell concentration increased the cytokine production increased, although in some strains the cytokine levels started to decline over cell concentration increased the cytokine production increased, although in some strains the cytokine levels started to decline over cell concentration of $250\mu\textrm{g}$/ml. the strains which showed high cytokine-stimulating activity generally showed greater production of nitric oxide even though differences were less between strains. Selected Bifidobacterium strains were compared for their fermentation capability in saccharified rice solution and in apple pomace mixture.

  • Water extracts of Acanthopanax divaricatus var. albeofructus (ADA) fruits were used to treat hPBMC to determine the mechanisms for the immunomodulatory effects. The secretion level of various cytokines including Th-1 type (IL-2, L-12, $IFN-{\gamma}$ and $TNF-{\alpha}$) and Th-2 type (IL-6, IL-8 and IL-10) were measured using ELISA. A significant increase of Th-1 type cytokine secretion was observed in the presence of extract while Th-2 cytokine, IL-6 was suppressed. Our results suggest that ADA fruit extract may influence the anticancer immune responses towards a predominance of Th-1 cytokines in the immune system.

  • In this paper, we highlight the development of a web application system. Its main objective is to provide pathway visualization functionalities for inter-cytokine relationships, as well as for other types of relationships, with a specific cytokine(s) of interest. A natural language processor is first used to extract information from a certain web page that concerns the cytokine(s) of interest. The results obtained are then further processed and then displayed graphically to the user. The system displays how the cytokine(s) of interest interacts with other cytokines and cells. Useful information such as the type of reaction and catalyst involved, if any, are also displayed. In addition, the system also offers functionalities for graphical manipulations of the visualized pathways. The system has been shown to provide better overview, and hence, improved learning to readers who are new to this field by virtue of accurate inputs obtained from the natural language processing module.

  • Nelumbo nucifera Gaertn has been usedas a traditional remedy and food source in South Korea. It promotes gastrointestinal function and controls blood pressures. Nelumbo nucifera Gaertn water extracts supplement at 5, 10, 50, 100, 250, 500, $1,000{\mu}g/mL$ after a 48 h pre-treatment with the mitogen (ConA or LPS) increased the mouse splenocytes proliferation. Water extract supplement also increased the cytokine production ($IL-1{\beta}$, $TNF-{\alpha}$ and $IFN-{\gamma}$), measured by a cytokine ELISA kit. For the result of in vitro study, the proliferation of splenocytes and cytokine production activated by peritoneal macrophages increased when water extracts were supplemented in the range of $50{\sim}500{\mu}L/mL$ concentration. Specifically, the levels of the splenocytes proliferation, $IL-1{\beta}$, $TNF-{\alpha}$ and $IFN-{\gamma}$ were the highest at $250{\mu}L/mL$ concentration. This in vitro study suggestedthat supplementation with Nelumbo nucifera Gaertn water extracts may enhance the immune function by regulating the splenocyte proliferation and enhancing the cytokine production activating macrophage in vitro.

  • Codonopsis lanceolatae have been used as one of the traditional remedies as well as food source. We previously reported that in vitro supplementation of Codonopsis lanceolatae water extracts enhanced the splenocytes proliferation compared to the control group. This study, the combined immunomodulative effect of water extract Codonopsis lanceolatae was Seven to eight weeks old mice(balb/c) was fed ad libitum on chow diet and water extract of Codonopsis lanceolatae was orally administrated every other day for four weeks at two different concentrations(50 and 500 mg/kg B.W.). The production of cytokine(IL-2, IL-10 and IFN-${\gamma}$), secreted by macrophages stimulated with LPS or not, were detected by ELISA assay using the cytokine kit. The result of ex vivo study showed that the IL-2, IL-10 and IFN-${\gamma}$ was detected at 500 mg/kg B.W. supplementation group with LPS stimulation in all cases. Also, ratio of IFN-${\gamma}$, IL-10 was the range of 3${\sim}$7 with mitogen stimulation such as Con A and LPS. In conclusion, this study suggests that Codonopsis lanceolatae extracts may enhance the immune function by regulating the cytokine(IL-2, IL-10 and IFN-${\gamma}$) prodution capacity by activated macrophages in mice.
