In this study, the effects of fermented goat milk (F-GM) on immunological activity and physical strength were examined. Splenocytes obtained from mice administered with F-GM showed increased responsinveness to mitogens, concanavalin-A (ConA), and lipopolysaccharide (LPS). Treatment with F-GM also significantly augmented production of interleukin (IL)-2 and interferon (IFN)-${\gamma}$, but not IL-4 or IL-10 from ConA-stimulated splenocytes. The activity of F-GM administration to enhance production of IL-2 and IFN-${\gamma}$ was confirmed based on mRNA expression of these cytokines by reverse transcription polymerase chain reaction. After immunization with keyhole limpet hemocyanin (KLH, 20 mg/mouse), mice administered F-GM showed significantly higher antibody titers against KLH than those of phosphate-buffered saline-treated mice, and showed the highest titer 5 weeks after KLH immunization. Analysis for determining isotypes of antibodies revealed that administration of F-GM elicited KLH-specific antibody titers of IgG1, IgG2a, and IgM. In a delayed type hypersensitivity (DTH) test carried out 7 weeks after the primary immunization, F-GM-treated mice showed a higher DTH reaction than the control mice. Furthermore, the swimming test found that administration of F-GM significantly increased swimming time. These results suggest that administration of F-GM enhances not only immune responses against antigens but also physical strength.

CSBHT is known to improve immunological response in mice and humans. In this study, CSBHT effect was examined in the context of CD4+ T cells' survival and TCR/CD3 induced activation responses. Spleen cells from 8 week BALB/c mice were cultured in CSBHT containing medium without activation for 24, 48 hr. The MTS assay and revealed that CSBHT did not stimulate spleen lymphocytes as mitogen. Spleen lymphocytes were treated with anti-CD3e/anti-CD28 antibodies for 48hr. Flow cytometry revealed that activity of T cell decreased with CSBHT concentration. CD4+ T cells were isolated and cultured ,in CSBHT containing medium for 48 hr. CSBHT did not affect survival of sorted CD4+ T cells without any involvement of APC. In order to evaluate the direct effect of CSBHT on helper T cells's proliferative capacity prior to activation, CD4+ T cells are isolated after 24hr of culture in CSBHT containing medium and activated with and without anti-CD3e/anti-CD28 activation for 48hr. A higher level of CD69 was observed in 1 ㎍/㎖ of CSBHT treatment than control using flow cytometry. But low CD69 expression was observed in 5㎍/㎖ of CSBHT treatment. Expression of mRNA for cytokines in CD4+ T cell revealed that IL-2 expression was increased in 1 ㎍/㎖. The expression of IL-2R α, INF- γ were increased with concentration. On the other hand mRNA of IL-4 was decreased in dose dependent manner. Results suggest that CSBHT may be desirable for CD4+ T cell's activity in immune responses. Further more, CSBHT may relatively activate Th1 and inactivate Th2.

Immunological activities of the combined-administration of Ginseng Radix Rubra and Vitis Fructus were examined in C57BL/6 mice. Ginseng Radix Rubra and Vitis Fructus were extracted with distilled water or 40% ethyl alcohol. Ginseng Radix Rubra water extracts (GW), the mixture (1:1) of Ginseng Radix Rubra and Vitis Fructus water extracts [GVW(1:1)], the mixture (1:3) of Ginseng Radix Rubra and Vitis Fructus water extracts [GVW(1:3)], 40% ethyl alcohol extracts of Ginseng Radix Rubra (GE), the mixture (1:1) of Ginseng Radix Rubra and Vitis Fructus 40% ethyl alcohol extracts [GVE(1:1)] and the mixture (1:3) of Ginseng Radix Rubra and Vitis Fructus 40% ethyl alcohol extracts [GVE(1:3)] were administered p.o. once a day for 7 days, respectively. GVW(1:1) and GVW(1:3) decreased the viability of thymocytes increased by GW, but GVE(1:1) and GVE(1:3) increased the viability of thymocytes decreased by GE. GVW(1:1) and GVW(1:3) increased the viability of splenocytes decreased by GW or GE. Also, GVW(1:1) and GVE(1:1) enhanced the population of helper T cell in thymocytes, and GVE(1:1) and GVE(1:3) decreased the population of cytotoxic T cells increased by GE. Furthermore, GVW(1:1), GVW(1:3), GVE(1:1) and GVE(1:3) enhanced the population of $B220^+$ cells decreased by GW or GE, and decreased the population of $Thyl^+$ cells increased by GW or GE, and decreased the population of splenic $CD4^+$ cells increased by GW or GE. In addition, GVW(1:1) and GVW(1:3) decreased the phagocytic activity and the production of nitric oxide in peritoneal macrophages increased by GW, but GVE(1:1) and GVE(1:3) enhanced the phagocytic activity and the production of nitric oxide in peritoneal macrophages decreased by GE. These results suggest that Vitis Fructus has an regulative action on immune response of Ginseng Radix Rubra.

In this study, we show that Mycobacterium avium subsp. paratuberculosis MAP1305 induces the maturation of bone marrow-derived dendritic cells (BMDCs), a representative antigen presenting cell (APC). MAP1305 protein induces DC maturation and the production of pro-inflammatory cytokines (Interleukin (IL)-6), tumor necrosis factor (TNF)-${\alpha}$, and IL-$1{\beta}$) through Toll like receptor-4 (TLR-4) signaling by directly binding with TLR4. MAP1305 activates the phosphorylation of MAPKs, such as ERK, p38MAPK, and JNK, which is essential for DC maturation. Furthermore, MAP1305-treated DCs transform naive T cells to polarized $CD4^+$ and $CD8^+$ T cells, thus indicating a key role for this protein in the Th1 polarization of the resulting immune response. Taken together, M. avium subsp. paratuberculosis MAP1305 is important for the regulation of innate immune response through DC-mediated proliferation of $CD4^+$ and $CD8^+$ T cells.

This study was designed to clarify the morphometrical change of lymph node, deep cortex and lymph follicles in draining lymph nodes of young mice in response to local injection of lipopolysaccharide(LPS). 1. In the group stimulated with LPS, aged 0 day and 3 days, the number of lymph follicles were not significantly different from those of control group. 2. In the group two to four weeks after injection with LPS, aged five days and one week, the number of lymph follicles were significantly increased from those of control group. 3. In the group one to four weeks after injection with LPS, aged 0 day, three days, five days and one week, the area of lymph node and deep cortex increased about 1.5-3 times more than that of the control group. 4. In the group two to four weeks after injection with LPS, aged three days, five days and one week, the lymph follicles(the area: larger than 0.1 mm2) were increased from those of control group. 5. In the group two to four weeks after injection with LPS, aged five days and one week, the lymph follicles(the area: smaller than 0.01 mm2) were increased from those of control group. In view of these experimental findings, the formation of lymph follicles were induced by LPS stimulation from 5 days to one week after birth. The newley formed lymph follicles area in response to LPS may be less than $0.01mm^2$.

Tobacco smoking (TS) has been known as one of the most potent risk factors for airway inflammatory diseases. However, there has been a paucity of information regarding the immunologic alteration mediated by TS in patients with chronic rhinosinusitis with nasal polyps (CRSwNP). To identify the effect of TS, we harvested human tissue samples (never smoker: n=41, current smoker: n=22, quitter: n=23) and analyzed the expression of epithelial-derived cytokines (EDCs) such as IL-25, IL-33, and thymic stromal lymphopoietin. The expressions of Th2 cytokines and total serum IgE showed a type-2 inflammatory alteration by TS. In addition, the epithelial marker E-cadherin and epithelial-mesenchymal transition (EMT)-associated markers (N-cadherin, α-SMA, and vimentin) were evaluated. Histological analysis showed that EDC expressions were upregulated in the current smoker group and downregulated in the quitter group. These expression patterns were consistent with mRNA and protein expression levels. We also found that the local Th2 cytokine expression and IgE class switching, as well as serum IgE levels, were elevated in the current smoker group and showed normal levels in the quitter group. Furthermore, the expressions of E-cadherin decreased while those of N-cadherin, α-SMA, and vimentin increased in the current smoker group compared those in the never smoker group. Taken together, these results indicate that TS contributes to the deterioration of pathogenesis by releasing local EDCs and Th2 cytokines, resulting in EMT in patients with CRSwNP. We verified that alterations of immunological response by TS in sinonasal epithelium can play a vital role in leading to CRSwNP.
Potassium $(K^+)$ channels are present in airway smooth muscle cells, and their activation results in hyperpolarization and relaxation. Because these effects may have therapeutic relevance to hypersensitivity and asthma, we examined the effect of a potassium channel activator, cromakalim (BRL 34915, CK) on the release of mediators from superfused tracheal and parenchymal strips after passive sensitization with $IgG_1$ antibody. Both tissues were superfused with CK $(2{\times}10^{-6}\;M)$ for 30 min and challenged with CK and antigen (Ox-HSA). Using monodispersed, partially purified, highly purified guinea pig lung mast cells, we also examined the effect of CK on mediator release from these cells after passive sensitization with $IgG_{1}$ antibody $({\alpha}-OA)$. Guinea pig lung mast cells were purified using enzyme digestion method, count current elutriation, and discontinuous Percoll density gradient. After CK pretreatment, passively sensitized mast cells were challenged with varying concentration of antigen (OA, immunological stimuli) or with varying concentration of calcium ionophore (CaI, non-immunological stimuli). Histamine (Hist) release was determined by spectrophotofluorometry, and leukotrienes (LT) by radioimmunoassy. CK pretreatment decreased Hist by 35% and LT release by 40% in the antigen-induced tracheal tissue after $IgG_1$ sensitization but did not decrease the contractile response. In the antigen-induced parenchymal tissue CK decreased Hist release by 25% but poorly decreased LT. Both immunologic and non-immunologic stimuli caused a dose-dependent release of Hist and LT from monodispersed, partially purified and highly purified lung mast cells. Verification of LT release was obtained by the use of 5-lipoxygenase inhibitor, A64077 (Zileuton). CK decreased Hist and LT release by 20% respectively in the OA-induced guinea pig lung mast cells after $IgG_1$ sensitization. The inhibitory effects of CK on the Hist and LT release in the Ox-HSA-induced airway smooth muscle tissues or in the OA-induced and CaI-induced mast cells after $IgG_1$ sensitization were completely blocked by TEA and GBC. These studies show that guinea pig lung mast cells seem to be an important contributor to LT release, and that CK (which has been known as an airway smooth muscle relaxant) can in part act to inhibit mediator release in the antigen-induced airway smooth muscle, and that CK may also act to inhibit mediator release in the OA-induced and CaI-induced highly purified mast cells. These results suggest that Hist and LT release evoked by mast cell activation might in part be associated with $K{^+}4 channel activity.
This study was conducted to investigate feeding effects of the high pressure boiled extracts (HPBE) of the Ogol chicken with herbs on glucose, hormones and immunological response (cytokine, specific antibody) of serum in the rat which fed either with normal feed (T$_1$), normal feed + herb HPBE (T$_2$), normal feed + Ogol chicken HPBE (T$_3$), normal feed + mixture of cross-bred Ogol chicken HPBE (T$_4$) hydrolyzed with Flavourzyme 0.1% for 35 days. During experimental period, there was a weak trend to have a higher glucose content for the T$_4$ group with 102.27${\pm}$5.95 mg/dL, but it was not significantly higher than other treatments. For insulin level, T$_1$ group showed numerically a slightly higher level with 6.79${\pm}$4.64 ${\mu}$IU/mL, but the difference was not significant in statistic term due likely to a large variation in comparison with other treatments. The treatments did not significantly alter testosterone level in rat plasma with 1.09, 1.46, 0.98, 1.13 ng/mL in T$_1$, T$_2$, T$_3$ and T$_4$, respectively. T$_4$ treatment increased the aldosterone level to a significantly (p<0.05) higher level (273.33 ng/dL) than other treatments. The extract treated rat showed a tendency in the cortisol level of lower levels than the control group, particularly, it was significantly (p<0.05) lower in T$_3$ group than other groups. T$_3$ and T$_4$ groups showed higher levels for interlukin-4 (IL-4) and anti-BSA IgG in immune cells and plasma. T$_2$, T$_3$ and T$_4$ treatments showed a slightly higher levels in v-interferon (INF-r) than the control, with a greater effect for T4 treatments. These results suggested that HPBE of the cross-bred Ogol chicken hydrolyzed with Flavourzyme increased immunological activity and decreased the concentration of cortisol and aldosterone hormones.
Background : We have recently reported that airway epithelial cells can produce RANTES and IL-8 in response to the stimulation of tubercle bacilli suggesting a certain role of airway epithelial cells in the pathogenesis of pulmonary tuberculosis. The pathogenesis of tuberculosis is determined by several factors including phagocytosis, immunological response of host, and virulence of tubercle bacilli. Interestingly, there have been reports suggesting that difference in immunological response of host according to the virulence of tubercle bacilli may be related with the pathogenesis of tuberculosis. We, therefore, studied the expressions and productions of RANTES and IL-8 in airway epithelial cells in response to tubercle bacilli(H37Rv, virulent strain and H37Ra, avirulent strain), in order to elucidate the possible pathophysiology of pulmonary tuberculosis. Methods : Peripheral blood monocytes were isolated from normal volunteers. Peripheral blood monocytes (PBM) were stimulated with LPS($10{\mu}g/ml$), H37Rv, or H37Ra($5{\times}10^5$ bacilli/well) along with normal control for 24 hours. A549 cells were stimulated with supernatants of cultured PBM for 24 hours. ELISA kit was used for the measurement of $TNF{\alpha}$ and IL-$1{\beta}$ production in supernatants of cultured PBM and for the measurement of RANTES and IL-8 in supernatants of cultured A549 cells. Northern blot analysis was used for the measurement of RANTES and IL-8 mRNA expression in cultured A549 cells. Results : $TNF{\alpha}$ and IL-$1{\beta}$ productions were increased in cultured PBM stimulated with LPS or tubercle bacilli(H37Rv or H37Ra) compared with the control. There was, however, no difference in $TNF{\alpha}$ and IL-$1{\beta}$ production between cultured PBM stimulated with H37Rv and H37Ra. RANTES and IL-8 expressions and productions were also increased in cultured A549 cells stimulated with LPS or tubercle bacilli compared with the control. RANTES and IL-8 mRNA expressions were significantly increased in cultured A549 cells stimulated with H37Ra-conditioned media(CM) compared with A549 cells stimulated with H37Rv-CM (p<0.05). However, there was no difference in RANTES and IL-8 productions between A549 cells stimulated with H37Rv-CM and H37Ra-CM. Conclusion : Airway epithelial cells can produce the potent chemokines such as RANTES and IL-8, in response to the stimulation of tubercle bacilli. These results suggest that airway epithelial cells may play a certain role in the pathogenesis of pulmonary tuberculosis. However, the role of airway epithelial cells in the pathogenesis of tuberculosis according to the virulence of tubercle bacilli was not clear in this study.
The present experiments were designed to study the influence of WalgookwhanhabBojoongikgitang on immune functions of Balb/c mice under stress condition. WalgookwhanhabBojoongikgitang was orally administered to the mice for 15 days. On the 10th day the mice were immunized with sheep red blood cells (SRBC) and then subjected to electric footshock for 5 days (2 sessions a day, 11 footshocks a 31 min-session). The immune responses to SRBC were determined by means of hemagglutination and BIT cell populations in the spleen were studied by FACS analysis on the 16th day. The results were as follows. 1. After electric footshock, IDlce became sluggish and crowded to one side of the cage. Increased antibody titer for SRBC, increased B cell population, and decreased T cell population in the spleen were also observed. These results confirm that electric footshock caused stress inducing immunological and behavioral changes in Balblc mice. 2. Walgookwhanhab-Bojoongikgitang administration significantly antagonized the effect of electric footshock on the antibody titer for SRBC. As a result, antibody titers for SRBC in the mice treated with Walgookwhanga-Bojoongikgitang were maintained at the similar levels as those of control group mice even after the electric foots hock. 3. Walgookwhanhab-Bojoongikgitang administration also antagonized the effect of electric footshock on the BIT populations in spleen. As a result, Band T populations in the mice treated with Walgookwhanhab-Bojoongikgitang were maintained at the similar levels as in the control group mice even after the electric footshock. Taken together, Walgookwhanhab-Bojoongikgitang seem to help Balb/c mIce to maintain their humoral immune response and immune cell populations at a normal range under the stress conditions, suggesting its possible therapeutic use as a immune function modulator.
