  • This study examined the immunomodulatory activities of apple seed extracts (ASE). The immunomodulatory effects were estimated through nitric oxide production, cytokine induction, protein expression of inducible nitric oxide synthase (iNOS), and the phosphylation of mitogen-activated protein kinases (MAPKs) and inhibitory kappa $B{\alpha}$ ($I{\kappa}B-{\alpha}$) in the RAW 264.7 macrophage cell line. In the cytotoxicity asay, ASE (31 to $250{\mu}g/mL$) did not induce cytotoxicity; thus, the optimal concentration of ASE was confirmed to be less than $250{\mu}g/mL$. Nitric oxide (NO) and cytokines (tumor necrosis factor (TNF)-${\alpha}$ and interleukin (IL)-6) production significantly increased in a dose-dependent manner. Similarly, the protein expression of iNOS and the phosphorylation of MAPKs and $I{\kappa}B-{\alpha}$ were also increased by ASE treatment. Overall, our results suggest that extracts from apple seeds potentially have immunomodulatory activities on macrophages.

  • Osteoarthritis (OA) is a degenerative disease characterized by the progressive degradation of joint cartilage and is accompanied by secondary inflammation of synovial membranes. The purpose of this study describes a preliminary evaluation of the anti-inflammatory activity on test material of Litsea japonica. fruit (LJTM) Also, this study was to evaluate the effects of LJTM on the joint cartilage of rat with OA induced by monosodium iodoacetate (MIA). To study for anti-inflammatory agents effectively, we first examined the inhibitory effect of the LJTM on the production of pro-inflammatory factors and cytokines stimulated with lipopolysaccharide. We identified anti-nociceptive effects of the LJTM by using in vivo peripheral and central nervous pain models. In addition, the aim of this study was to evaluate the effects on mRNA expression of MMP-2, -3, -7, -9, -13, TIMP-1 and –2 in cartilage of OA. In the LJTM inhibited production of pro-inflammatory mediators (NO and PGE2) and pro-inflammatory cytokines (TNF-α and IL-6). In cartilage, Expression of MMPs and TIMPs mRNA was suppressed in LJTM treatment group than in the control group. This study suggests that LJTM are potential candidates as anti-inflammation and anti-osteoarthritis agents (painkillers) for the treatment of OA.

  • This study investigated the antioxidant and anti-inflammatory activity of ethanol extract from the flowers of Weigela subsessilis (WS-E) in lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages. The total polyphenol and flavonoid content was 719.19±0.04 μg tannic acid equivalents/ml and 644.87±0.02 μg quercetin equivalents/ml, respectively. The antioxidant activities of WS-E were measured by 1,1-diphenyl-2-picrylhydrazyl (DPPH) and superoxide anion radical scavenging activity. The antioxidant activities of WS-E increased markedly, in a dose-dependent manner. To screen for anti-inflammatory agents, the inhibitory effects of WS-E on the production of proinflammatory cytokines in the LPS-stimulated RAW 264.7 macrophages was examined. WS-E had no effect on cell viability at a concentration of 100 μg/ml. Nitric oxide (NO) and interleukin (IL)-6 production were inhibited in a dose-dependent manner (p<0.05). WS-E had no effect on the production of tumor necrosis factor (TNF)-α at a concentration of 0.16–20 μg/ml but induced TNF-α at a concentration of 100 μg/ml. Inducible nitric oxide synthase (iNOS) expression was also inhibited at lower concentrations (p<0.05). In addition, WS-E reduced the activation of nuclear factor (NF)-κB by inhibition of inhibitoy (I) κB phosphorylation in RAW 264.7 macrophages upon stimulation with LPS (100 ng/ml) for 24 h but not that of mitogen-activated protein kinase (MAPK). These results suggest that WS-E may be a useful antioxidant and anti-inflammatory agent in functional cosmetics.

  • Although hypoxic/ischemic injury is thought to contribute to the incidence of Alzheimer disease (AD), the molecular mechanism that determines the relationship between hypoxia-induced β-amyloid (Aβ) generation and development of AD is not yet known. In this study, we investigated the protective effects of Acorus gramineus Soland. (AGS) on oxygen-glucose deprivation/reoxygenation (OGD/R)-induced A β production in SH-SY5Y human neuroblastoma cells. Pretreatment of these cells with AGS significantly attenuated OGD/R-induced production of reactive oxygen species (ROS) and elevation of levels of malondialdehyde, nitrite (NO), prostaglandin E2 (PGE2), cytokines (TNF-α, IL-1β and IL-6) and glutathione, as well as superoxide dismutase activity. AGS also reduced OGD/R-induced expression of the apoptotic protein caspase-3, the apoptosis regulator Bcl-2, and the autophagy protein becn-1. Finally, AGS reduced OGD/R-induced Aβ production and cleavage of amyloid precursor protein, by inhibiting secretase activity and suppressing the autophagic pathway. Although supporting data from in vivo studies are required, our results indicate that AGS may prevent neuronal cell damage from OGD/R-induced toxicity.

  • Objectives : Taraxacum coreanum (TC) have been used as a traditional medicine to treat inflammatory diseases and anti-oxidant effect in Korea. However, the anti-inflammatory effect of TC water extract on lipopolysaccharide (LPS)-induced inflammation is not well-known. Therefore, this study was performed to identify the anti-inflammatory effect of TC on LPS induced inflammatory. Methods : RAW 264.7 cells were treated with 500 ng/mL of LPS. Water extracts of TC (0.1, 0.25, 0.5 mg/ml) was treated 1 h prior to LPS. Cell viability was measured by MTT assay. Levels of nitric oxide (NO) were measured with Griess reagent and pro-inflammatory cytokines were measured by enzyme-linked immunosorbent assay (ELISA) and real-time polymerase chain reaction (real-time PCR). We also examined molecular mechanisms such as mitogen-activated protein kinases (MAPKs) and nuclear factor-B ($NF-{\kappa}B$) activation by western blot. Results : Water Extract from TC itself did not have any cytotoxic effect in RAW 264.7 cells. TC treatment inhibited the production of NO production, and pro-inflamamtory cytokines such as interleukin (IL)-6 and $IL-1{\beta}$ on protein and mRNA levels. In addition, TC treatment inhibited the LPS-induced activation of MAPKs such as extracellular signal-regulated kinase1/2 (ERK1/2), p38 kinases (p38), c-Jun $NH_2$-terminal kinase (JNK) and $NF-{\kappa}B$. Conclusions : In summary, our result suggest that treatment of TC could reduce the LPS-induced inflammation. Thereby, TC could be used as a protective agent against inflammation. Also, this study could give a clinical basis that TC could be a drug or agent to prevent inflammation.

  • Background: Periodontitis is an inflammatory disease characterized by the breakdown of tooth-supporting tissues, leading to tooth loss. Aggregatibacter actinomycetemcomitans are major etiologic bacterium causing aggressive periodontitis. Ursodeoxycholic acid (UDCA), a hydrophilic gall bladder acid, has been used as an effective drug for various diseases related to immunity. The aim of this study was to investigate the effect of UDCA on the inflammatory response induced by A. actinomycetemcomitans. Methods: A human acute monocytic leukemia cell line (THP-1) was differentiated to macrophage- like cells by treatment with phorbol 12-mystristate 13-acetate (PMA) and used for all experiments. The cytotoxic effect of UDCA was examined by MTT assay. THP-1 cells were pretreated with UDCA for 30 min before A. actinomycetemcomitans infection and the culture supernatant was analyzed for various cytokine production by ELISA. The effect of UDCA on bacterial growth was examined by measuring optical densities using a spectrophotometer. Results: UDCA showed no cytotoxic effect on THP-1 cells, up to $80{\mu}M$ Ed highlight: Please confirm technical meaning. UDCA pretreatment inhibited the A. actinomycetemcomitans-induced $IL-1{\beta}$, $TNF-{\alpha}$, and IL-17A secretion in a dose-dependent manner. UDCA also inhibited IL-21 production at $60{\mu}M$. The production of IL-12 and IL-4 was not influenced by A. actinomycetemcomitans infection. Conclusion: These findings indicate that UDCA inhibits the production of inflammatory cytokines involved in innate and Th17 immune responses in A. actinomycetemcomitans-infected THP-1- derived macrophages, which suggests its possible use for the control of aggressive periodontitis.

  • Objectives This study was designed to examine the effect of Gleditsiae Fructus n-hexane (GSF_Hx) on two different groups (on the LPS-induced activation of Raw264.7 cells in vitro, and on the DNCB-induced activation of atopic dermatitis NC/Nga Tnd mice in vivo) to find index components and active components of Gleditsiae Fructus. Methods GSF_Hx was analyzed by HPLC profiling and confirmed echinocystic acid (EA), oleanolic acid (OA) as index components of Gleditsiae Fructus. Using GSF_Hx, EA, OA, we investigated IL-6, TNF-α, NO production by ELISA analysis and evaluated manifestations of MAPKs transcription factors and NF-κB p65 translocation by western blotting. During In vivo study, atopic dermatitis was induced on NC/Nga Tnd mice by DNCB and administered GSF_Hx, EA, OA orally, and checked skin lesions and measured skin clinical score. Serum IgE level, Th1 and Th2 cytokines secretion and modulating molecular mediators and immune cells in the spleenocyte culture supernatant, PBMCs, ALN and dorsal skin were also measured by real-time PCR. Then, skin rash was evaluated and mast cell distribution was verified by H&E and toluidine blue staining on dorsal skin. Results It is possible that GSF_Hx, EA and OA reduce inflammation and allergic response of atopic dermatitis by suppressing Th1 and Th2 cytokines secretion and modulating molecular mediators and immune cells. They also had moisturizing effect by raising vitality of ceramide in dorsal skin of atopic dermatitis NC/Nga Tnd mice. However, EA particularly had better overall activity data than OA, that EA could be a more effective active component of Gleditsiae Fructus than OA. Conclusions Based on the inflammatory reduction property with moisturizing effect, GSF_Hx may play a role in effective treatment for atopic dermatitis.

  • The treatment of atopic dermatitis (AD) is challenging due to its complex etiology. From epidermal disruption to chronic inflammation, various cells and inflammatory pathways contribute to the progression of AD. As with immunosuppressants, general inhibition of inflammatory pathways can be effective, but this approach is not suitable for long-term treatment due to its side effects. This study aimed to identify a plant extract (PE) with anti-inflammatory effects on multiple cell types involved in AD development and provide relevant mechanistic evidence. Degranulation was measured in RBL-2H3 cells to screen 30 PEs native to South Korea. To investigate the anti-inflammatory effects of Parasenecio auriculatus var. matsumurana Nakai extract (PAE) in AD, production of cytokines and nitric oxide, activation status of FcεRI and TLR4 signaling, cell-cell junction, and cell viability were evaluated using qRT-PCR, western blotting, confocal microscopy, Griess system, and an MTT assay in RBL-2H3, HEK293, RAW264.7, and HaCaT cells. For in vivo experiments, a DNCBinduced AD mouse model was constructed, and hematoxylin and eosin, periodic acid-Schiff, toluidine blue, and F4/80-staining were performed. The chemical constituents of PAE were analyzed by HPLC-MS. By measuring the anti-degranulation effects of 30 PEs in RBL-2H3 cells, we found that Paeonia lactiflora Pall., PA, and Rehmannia glutinosa (Gaertn.) Libosch. ex Steud. show an inhibitory activity of more than 50%. Of these, PAE most dramatically and consistently suppressed cytokine expression, including IL-4, IL-9, IL-13, and TNF-α. PAE potently inhibited FcεRI signaling, which mechanistically supports its basophil-stabilizing effects, and PAE downregulated cytokines and NO production in macrophages via perturbation of toll-like receptor signaling. Moreover, PAE suppressed cytokine production in keratinocytes and upregulated the expression of tight junction molecules ZO-1 and occludin. In a DNCB-induced AD mouse model, the topical application of PAE significantly improved atopic index scores, immune cell infiltration, cytokine expression, abnormal activation of signaling molecules in FcεRI and TLR signaling, and damaged skin structure compared with dexamethasone. The anti-inflammatory effect of PAE was mainly due to integerrimine. Our findings suggest that PAE could potently inhibit multi-inflammatory cells involved in AD development, synergistically block the propagation of inflammatory responses, and thus alleviate AD symptoms.

  • The present study was conducted to investigate anti-nociceptive and anti-inflammatory effects of the leaves of Ilex latifolia Thunb (I. latifolia) in in vivo and in vitro. Writhing responses induced by acetic acid and formalin- and thermal stimuli (tail flick and hot plate tests)-induced pain responses for nociception were evaluated in mice. I. latifolia (50 - 200 mg/kg, p.o.) and ibuprofen (100 mg/kg, p.o.), a positive non-steroidal anti-inflammatory drug (NSAID), inhibited the acetic acid-induced writhing response and the second phase response (peripheral inflammatory response) in the formalin test, but did not protect against thermal nociception and the first phase response (central response) in the formalin test. These results show that I. latifolia has a significant anti-nociceptive effect that appears to be peripheral, but not central. Additionally, I. latifolia (50 and $100{\mu}g/mL$) and 3,5-di-caffeoyl quinic acid methyl ester ($5{\mu}M$) isolated from I. latifolia as an active compound significantly inhibited LPS-induced NO production and mRNA expression of the pro-inflammatory mediators, iNOS and COX-2, and the pro-inflammatory cytokines, IL-6 and $IL-1{\beta}$, in RAW 264.7 macrophages. These results suggest that I. latifolia can produce antinociceptive effects peripherally, but not centrally, via anti-inflammatory activity and supports a possible use of I. latifolia to treat pain and inflammation.
