  • Falun Gong (FG) is an advanced system of cultivation and practice, which is beneficial for both mind and body. In this study we investigated the effects of FG on the production of cytokines in FG practitioner (FGP). To study whether plasma cytokines levels were affected by FG, their levels were analyzed. The amount of $interferon-{\gamma}$ $(IFN-{\gamma})$, interleukin (IL)-2, IL-4 and IL-6 (2.5-fold for $IFN-{\gamma}$, 1.2-fold for IL-2, 2.1-fold for IL-4 and 2.5-fold for IL-6, respectively) were significantly higher in the FGP group than normal group (P<0.05). Peripheral blood mononuclear cells obtained from normal healthy control and FGP were cultured for 24 h in the presence or absence of lipopolysaccharide. The amount of $IFN-{\gamma}$, IL-2, IL-4 and IL-6 in culture supernatant was quantified. However, there were no significant differences in the level of the same cytokines between the normal and FGP group. These data suggest that FG cultivation may contribute to immune-enhancement in vivo.

  • Jeongshin-tang (JST) is a Korean herbal prescription, which has been successfully applied for the various neuronal diseases. However, it's effect remains unknown in experimental models. To investigate the biological effect of JST in Alzheimer's disease (AD) in vitro model, we analized the production of interleukin (IL)-6 and IL-8, and expression of cyclooxygenase (COX)-2 in IL-1β plus β-amyloid [25-35] fragment (A)-stimulated human astrocytoma cell line U373MG. JST alone had no effect on the cell viability. The production of IL-6 and IL-8 was significantly inhibited by pretreatment with JST (1mg/㎖) on IL-1β plus A-stimulated U373MG cells. Maximal inhibition rate of IL-6 and IL-8 production by JST was about 41.22% (P<0.01) and 34.45% (P<0.05), respectively. The expression level of COX-2 protein was up-regulated by IL-1β plus A but the increased level of COX-2 was inhibited by pretreatment with JST (1 mg/㎖). These data indicate that JST has a regulatory effect on cytokine production and COX-2 expression, which might explain it's beneficial effect in the treatment of AD.

  • Objective: With the onset of stroke, white blood cells release several proinflammatory cytokines, including interleukin (IL)-6, IL-10, and tumor necrosis factor $(TNF)-{\alpha}$. It has been proven in previous studies that the release of these cytokines is related to the extent of damage to the brain and to overall prognosis. However, no studies have yet been performed to determine the connection with IL-6 and IL-10. Thus, this study is performed to see whether polymorphisms of IL-6, IL-10, and $TNF-{\alpha}$ genes that show increased serum concentration with the onset of stroke are related to stroke attack in Koreans. Methods : Peripheral blood samples derived from patients with stroke (n=100) and healthy controls (n=100) were taken under informed consent. In subjects with stroke, blood samples were obtained within 24 hours of stroke onset. Genomic DNA was isolated using the Wizard DNA Purification Kit (Promega, Madison, WI). Results : 1. Subjects with Heterozygote (GA) and Homozygote (AA) $TNF-{\alpha}$ gene types showed 2.433 and 20.457 times higher risks of being attacked by stroke, respectively, compared to subjects with wild type (GG) $TNF-{\alpha}$ gene type. The data was still statistically significant after adjusting for age, sex, history of smoking, and history of alcohol drinking. 2. Subjects with Homozygote (CC) IL-6 gene type showed 182.033 times higher risk of being attacked by stroke, compared to subjects with wild type (GG) IL-6 genes. This data was statistically insignificant (p=0.700). The data was still statistically insignificant after adjusting for age, sex, history of smoking, and history of alcohol drinking. 3. Subjects with Heterozygote (GA) and Homozygote (GG) IL-10 gene types showed 8.785 and 3.303 times higher risks of being attacked by stroke, respectively, compared to subjects with wild type (AA) IL-10 genes. The data was still statistically insignificant after adjusting for age, sex, history of smoking, and history of alcohol drinking. Conclusion : Our results suggest that the investigated $TNF-{\alpha}$ and IL-10 gene polymorphisms play an important role in stroke attack, but IL-6 gene polymorphism has not been found to associated with stroke.

  • Acorns have been used as a traditional remed as well as food source. However, few studies on their immunomodulating effects have been reported. In this study, the combined immunomodulative effect of a water extract of acorns was tested on seven to eight weeks old mice(balb/c). The mice were fed ad libitum on a chow diet, and a water extract of the plant mixture was orally administered every other day for four weeks at two different concentrations(50 and 500 mg/kg B.W.). The production of cytokine(IL-$1{\beta}$, IL-6, IL-2, IL-10, IFN-$\gamma$), secreted by macrophages stimulated with LPS or not, detected by ELISA assay using cytokine kit. After 48 h of incubation with mitogen(ConA or LPS) ex vivo study showed that cytokine (IL-$1{\beta}$, IL-6, IL-2, IL-10, IFN-$\gamma$) was detected in both of the 50 and 500 mg/kg B.W. supplementation groups with LPS stimulation. The results of this study may suggest that supplementation with acorn water extract increase immune function by regulating cytokine production capacity by activated macrophages.

  • Interleukin-12 (IL-12) as an antitumor and interleukin-6 (IL-6) as an inflammatory cytokine, are immunomodulatory products that play important roles in responses in cancers and inflammation. We tested the association between two polymorphisms of IL-12(1188A>C; rs3212227) and IL-6 (-174 C>G) and the risk of bladder cancer in 261 patients and 251 healthy individuals. We also investigated the possible association of these SNPs in patients with high-risk jobs and smoking habits with the incidence of bladder cancer. The genotype distributions of IL-6 (-174 C/G) genotype were similar between the cases and the control groups; however, among patients with smoking habits, the association between IL-6 gene polymorphism and incidence of bladder cancer was significant. After a control adjustment for age and sex, the following results were recorded: CC genotype (OR= 2.11, 95%CI=1.56-2.87, p=0.007), GC genotype (OR=2.18, 95%CI=1.16-4.12, p=0.014) and GC+CC (OR=2.6, 95%CI=1.43-4.47, p=0.011). A significant risk of bladder cancer was observed for the heterozygous genotype (AC) of IL-12 (OR=1.47, 95%CI=1.01-2.14, p=0.045) in all cases, and among smokers (AC) (OR=3.13, 95%CI=1.82-5.37, p=0.00014), combined AC+CC (OR=3.05, 95%CI=1.8-5.18, p=0.000015). Moreover among high risk job patients, there was more than a 3-fold increased risk of cancer in the carriers of IL-12 beta heterozygous (OR=3.7, 95%CI=2.04-6.57, p=0.000056) and combined AC+CC(OR=3.29, 95%CI=1.58-5.86, p=0.00002) genotypes as compared with the AA genotype with low-risk jobs. As a conclusion, this study suggests that IL-12(3'UTR A>C) and IL-6 (-174 C>G) genotypes are significantly associated with an increased risk of bladder cancer in the Iranian population with smoking habits and/or performing high-risk jobs.

  • In this study, the anti-inflammatory effect of supercritical carbon dioxide selective extracts, which extract decursin and decursinol angelate, the vital active ingredients of Angelica gigas Nakai, in high yield, was measured compared to that of ethanol extracts. To measure the anti-inflammatory effect, the production of nitric oxide(NO), an inflammatory mediator, and interleukin(IL)-6 and IL-8, inflammatory cytokines, was measured. NO production was measured by Griess assay on Raw 264.7 cells induced inflammatory response by lipopolysaccharide(LPS), and IL-6 and IL-8 production was measured by enzyme-linked immunoadsorbent assay(ELISA) on human keratinocyte cell line(HaCaT) cells induced inflammatory response by tumor necrosis factor(TNF)-α. The amount of NO production was suppressed outstandingly by the supercritical carbon dioxide extracts compared to the ethanol extracts. The amount of IL-6 and IL-8 production was increased by the ethanol extracts, whereas statistically significantly inhibited by supercritical carbon dioxide extracts at the concentration of 6.25 ㎍/mL(P<0.01). Through these results, we confirmed that the supercritical carbon dioxide selective extracts of Angelica gigas Nakai could be used as an anti-inflammatory cosmeceutical material to alleviate atopic dermatitis.

  • This study was conducted to investigate the effect of Celeriac Extract on the production of pro-inflammatory cytokines. Inflammation is caused by pro-inflammatory cytokines TNF-α, IL-6, IL-1β and mediators such as free radicals. We investigated the effect of Celeriac Extract (1ug/mL, 10ug/mL, 100ug/mL) on the production of proinflammatory cytokines such as TNF-α, IL-6, IL-1β and NO by lipopolysaccharide (LPS)-stimulated RAW 264.7 cells. These results demonstrated that Celeriac Extract inhibited the production of TNF-α, IL-6 and NO, without cytotoxicity significantly. Therefore, these findings suggest that Celeriac Extract may attenuate inflammatory responses via inhibition of production of pro-inflammatory cytokines and NO.

  • Purpose: This study was performed to evaluate the anti-inflammatory effect of Eungapbang extract (EGB). Methods: To evaluate the anti-inflammatory effects of EGB, we nourished RAW 264.7 cell lines in the laboratory dish. Next, inflammatory cytokine concentrations were analyzed. Then, sera were prepared from blood after lipopolysaccharide (LPS) injection in chemically induced mouse models of intestinal inflammation, and Interleukin-1${\beta}$ (IL-1${\beta}$), interleukin-6 (IL-6) and tumour necrosis factor alpha (TNF-${\alpha}$) were measured using ELISA kits. Results: 1. EGB significantly suppressed the expression levels of IL-1${\beta}$ and NOS-II genes at 100, 50 and 10 ${\mu}g/m{\ell}$ concentrations, and IL-6, TNF-${\alpha}$ and COX-2 mRNAs at 100 and 50 ${\mu}g/m{\ell}$ concentrations. 2. EGB significantly reduced the production level of IL-1${\beta}$ and TNF-${\alpha}$ at 100${\mu}g/m{\ell}$ concentrations, and IL-6 at 100 and 50 ${\mu}g/m{\ell}$ concentrations. 3. EGB significantly decreased the production level of IL-1${\beta}$ and IL-6 in sera of acute inflammation induced mice. 4. EGB could suppress the expression level of IL-1${\beta}$ and IL-6 mRNA in spleen tissues in acute inflammation induced mice. Conclusion: On the basis of the above results, it is confirmed that the anti-inflammatory effects of EGB were recognized. Therefore, EGB is recommended as promising therapy for treatment of such ailments as pelvic inflammatory disease.

  • Innate lymphoid cells (ILCs) are critical immune-response mediators. Although they largely reside in mucosal tissues, the kidney also bears substantial numbers. Nevertheless, kidney ILC biology is poorly understood. BALB/c and C57BL/6 mice are known to display type-2 and type-1 skewed immune responses, respectively, but it is unclear whether this extends to ILCs. We show here that indeed, BALB/c mice have higher total ILCs in the kidney than C57BL/6 mice. This difference was particularly pronounced for ILC2s. We then showed that three factors contributed to the higher ILC2s in the BALB/c kidney. First, BALB/c mice demonstrated higher numbers of ILC precursors in the bone marrow. Second, transcriptome analysis showed that compared to C57BL/6 kidneys, the BALB/c kidneys associated with significantly higher IL-2 responses. Quantitative RT-PCR also showed that compared to C57BL/6 kidneys, the BALB/c kidneys expressed higher levels of IL-2 and other cytokines known to promote ILC2 proliferation and/or survival (IL-7, IL-33, and thymic stromal lymphopoietin). Third, the BALB/c kidney ILC2s may be more sensitive to the environmental signals than C57BL/6 kidney ILC2s since they expressed their transcription factor GATA3 and the IL-2, IL-7, and IL-25 receptors at higher levels. Indeed, they also demonstrated greater responsiveness to IL-2 than C57BL/6 kidney ILC2s, as shown by their greater STAT5 phosphorylation levels after culture with IL-2. Thus, this study demonstrates previously unknown properties of kidney ILC2s. It also shows the impact of mouse strain background on ILC2 behavior, which should be considered when conducting research on immune diseases with experimental mouse models.

  • Background and Aims : Cigarette smoking induces an inflammatory response in the airways, which may play a key role in the pathogenesis of chronic obstructive pulmonary disease. Interleukin-6 (IL-6) is one of the cytokines that plays an important role in inducing bronchial inflammation. The aim of this study was to determine if the level of the pro-inflammatory cytokine, Interleukin-6, is increased when the bronchial epithelial cells are exposed to a cigarette smoke extract (CSE) and an extract from stop smoking-aiding cigarettes, and examined the safety of these commercially available stop smoking-aiding cigarettes. Method : Bronchial epithelial cells were exposed to CSE from cigarette and stop smoking-aiding cigarettes for 24 hours. ELISA was used to measure the IL-6 levels in the supernatant from each condition. The IL-6 mRNA levels were measured by Taqman Real time RT-PCR. N-acetyl-L-cysteine(NAC) was added to each condition to determine if NAC can inhibit the release of IL-6 from the bronchial epithelial cells when they are exposed to CSE from cigarette and stop smoking-aiding cigarettes. Result : When bronchial epithelial cells were exposed to a CSE from cigarettes and stop smoking-aiding cigarettes, each type of CSE stimulated IL-6 production from the bronchial epithelial cells. The IL-6 mRNA level in the Bronchial epithelial cells was also elevated and NAC was found to inhibit the release of IL-6 from bronchial epithelial cells when they were exposed to the CSE from cigarettes and stop smoking-aiding cigarettes. Conclusion : Commercially available stop smoking-aiding cigarette can induce bronchial inflammation and can be harmful to smokers. Therefore, the safety of these cigarettes for smoking cessation should be evaluated.
