<P><B>Abstract</B></P> <P>The main aim of this study are to explore the role of bone-derived cells (BdCs) in ankylosing spondylitis (AS) and determine the underlying molecular mechanisms of IL-23 production. Primary BdCs were isolated from diced bone of facet joints obtained during surgery from seven AS patients and seven disease control (Ct) patients. Osteoblastic activity of BdCs was assessed by measuring their alkaline phosphatase activity and by alizarin red staining. Osteoblast and endoplasmic reticulum (ER) stress-related genes were assessed by quantitative PCR, immunoblotting, immunofluorescence, and immunohistochemistry. In addition, expression of IL-23 in response to BIX (selective BIP inducer X)-induced ER stress was evaluated by qPCR and ELISA. Protein interaction and binding to IL-23 promoter were confirmed by Immunoprecipitation and Chromatin immunoprecipitation, respectively. Transcript levels of genes involved in osteoblast function, as well as of the ER stress marker were higher in the AS group than the Ct group, and elevated RUNX2, BiP and IL-23 expression were observed in the BdCs, serum, and bone biopsies from the AS group. BIX-induced ER stress stimulated osteoblastic activity and IL-23 secretion by upregulating RUNX2 expression. Furthermore, in AS BdCs, RUNX2 interacted with C/EBPβ to bind to IL-23 promoter and RUNX2 knockdown suppressed IL-23 secretion. These finding may provide a molecular mechanism involved in sustained ER stress in AS BdCs stimulates the activation of RUNX2 and C/EBPβ genes, leading to IL-23 production.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Bones and its-derived cells from patients with AS showed an increase in ER stress. </LI> <LI> IL-23 cytokine was significantly higher in AS patients than in healthy controls. </LI> <LI> Inducing ER stress in AS exhibited an increase of bone-related genes. </LI> <LI> Inducing ER stress in AS was accompanied with augmentation of IL-23 cytokine. </LI> <LI> ER stress-induced RUNX2 is involved in IL-23 secretion and bone-related genes. </LI> </UL> </P>

본 실험에서는 동양에서 예로부터 민간요법이나 한방에서 주로 많이 쓰여지고 있는 8가지 종류의 한약재에 대해서 면역억제제로써 사용 가능성을 실험하였다. 그 결과 당귀, 산사, 어성초, 오가피, 황기의 추출물은 동종항원에 반응하는 순수분리 T세포의 증식을 농도 의존적으로 억제시켰다. 또한 이들 T세포의 증식에 있어서 필수적인 IL-2를 포함한 cytokine 즉, IL-2, IL-4, IL-10, IFN-γ의 생산량은 대조군에 비해 실험군에서 유의한 차이가 없었고 특히 T세포 증식에 필수적인 IL-2의 생산량의 변화가 거의 없었다. 이는 한약재에 의한 T세포의 증식억제 효과가 T세포증식에 필수적인 IL-2의 생산량을 억제하기 때문에 일어나는 결과가 아님을 알 수 있었다. 그리고 T세포의 살세포작용 억제를 직접적으로 측정하기 위하여 세포내 LDH의 양을 조사한 결과 모든 대조군에서 50%이상의 살세포작용 억제가 일어났고, 그중 특히 오가피와 황기에서는 100% 살세포작용 억제가 일어났다. 따라서 본 실험에 사용된 당귀, 산사, 어성초, 오가피, 황기 등의 5가지 약재가 부작용 없는 면역억제로써 사용 가능성이 높은 것으로 생각된다. In this experiment, we showed the immunosuppressive effects of herbal plant extracts on the alloantigen reactive proliferation and cytotoxicity. The extracts of Angelica gigas, Crataegus pinnatifida, Houttuynia cordata, Acanthopanax sessiliflorum and Astragalus membranaceus markedly suppressed on the pro- liferation of primary T cells stimulated with allogeneic spleen cells in a dose-dependent manner. The production of IL-2, IFN-γ, IL-4 and IL-10 in the alloreactive primary T cells showed no significant difference in the presence or absence of herbal plants extracts. Also the result of mixed lymphocyte reaction (MLR)-induced cytotoxic T lymphocyte (CTL) showed what is above a certain point 50% inhibition. Specially, the extracts of Acanthopanax sessiliflorum and Astragalus membranaceus com- pletely suppressed the killing activity of CTL. Theses results suggest that the extracts of 5 herbal plants can be used as immunosuppressive agents.

<P><B>Abstract</B></P> <P> <I>Staphylococcus aureus</I> membrane vesicles (MVs) aggravate atopic dermatitis (AD) through the delivery of bacterial effector molecules to host cells and the stimulation of inflammatory responses. This study investigated the inhibitory effect of thymol, a phenolic monoterpene found in essential oils derived from plants, on the worsening of AD induced by <I>S. aureus</I> MVs both <I>in vitro</I> and <I>in vivo</I>. The sub-minimal inhibitory concentrations of thymol disrupted <I>S. aureus</I> MVs. Intact <I>S. aureus</I> MVs induced the expression of pro-inflammatory cytokine (interleukin (IL)-1β, IL-6, and tumor necrosis factor-α) and chemokine (IL-8 and monocyte chemoattractant protein-1) genes in cultured keratinocytes, whereas thymol-treated <I>S. aureus</I> MVs did not stimulate the expression of these genes. Topical application of thymol-treated <I>S. aureus</I> MVs or treatment with thymol after intact <I>S. aureus</I> MVs to AD-like skin lesions diminished the pathology of AD. This included decreases in epidermal/dermal thickness and infiltration of eosinophils/mast cells, and inhibited expression of pro-inflammatory cytokine and chemokine genes in mouse AD model. Moreover, thymol significantly suppressed the Th1, Th2, and Th17-mediated inflammatory responses in AD-like skin lesions induced by <I>S. aureus</I> MVs, and reduced the serum levels of immunoglobulin (Ig) G2a, mite-specific IgE, and total IgE. In summary, thymol disrupts <I>S. aureus</I> MVs and suppresses inflammatory responses in AD-like skin lesions aggravated by <I>S. aureus</I> MVs. Our results suggest that thymol is a possible candidate for the management of AD aggravation induced by <I>S. aureus</I> colonization or infection in the lesions.</P> <P><B>Highlights</B></P> <P> <UL> <LI> The subMICs of thymol disrupt <I>S. aureus</I> membrane vesicles (MVs). </LI> <LI> Thymol-treated <I>S. aureus</I> MVs do not induce inflammatory responses in keratinocytes. </LI> <LI> Thymol inhibits worsening of AD-like lesions induced by <I>S. aureus</I> MVs. </LI> </UL> </P>

두부의 기능성 및 저장성을 향상시킬 목적으로 큰느타리버섯 균사체를 이용한 발효두부를 제조하여 물과 메탄올로 추출하여 면역세포 활성에 미치는 효과를 조사하였다. 큰느타리버섯 균사체를 배양하기 위한 최적 배지는 PD broth 배지인 것을 확인하였으며, 큰타리버섯 균사체를 이용한 두부의 최적 발효기간은 7일 정도가 적당하였다. 큰느타리버섯 균사체를 이용하여 발효한 두부의 물 및 메탄올추출물은 0.01 ㎍/mL 농도 이상에서 비장세포의 증식을 유도하였으며, 이들 추출물은 IL-6, IFN-γ 분비를 유도하는 것으로 나타났다. 발효두부 물 추출물은 대조군에 비해 대식세포의 일산화질소 생산을 1 ㎍/mL 농도 이상에서 유의적으로 증가시키는 것을 알 수 있었으며, 메탄올 추출물은 10 ㎍/mL 농도 이상에서 그 생산을 증가시켰다. 발효두부 추출물들은 대식세포가 분비하는 IL-6, TNF-α, IL-1β 및 GM-CSF 분비량을 유의하게 증가시켰다. 따라서 큰느타리버섯 균사체로 발효한 두부는 기능성 두부로 개발이 가능하리라 생각된다. In order to improve the functional benefits and storage properties of soybean tofu, fermented tofu was developed using Pleurotus eryngii mycelia. The immune activities of water and methanol extracts of the tofu were investigated. The optimal medium for the growth of Pleurotus eryngii mycelia was PD broth medium and the optimal fermentation period for the tofu was 7 days. The water and methanol extracts of the fermented tofu induced the proliferation of spleen cells at above 0.01 ㎍/mL. The water extract increased IL-2, IFN-γ production, while the methanol extract increased IFN-γ synthesis. The water and methanol extracts of the fermented tofu induced the NO production in RAW264.7 macrophage cells at above 1 ㎍/mL and above 10 ㎍/mL concentration, respectively. The extracts also significantly increased the production of IL-6, TNF-α, IL-1β and GM-CSF in the cells. These results suggest that the tofu fermented with Pleurotus eryngii mycelia could be developed as a functional tofu.

Effects of <i>Ecklonia cava</i> ethanolic extracts on airway hyperresponsiveness and inflammation in a murine asthma model: Role of suppressor of cytokine signaling

Kim, Se-Kwon,Lee, Da-Young,Jung, Won-Kyo,Kim, Ji-Hye,Choi, Inhak,Park, Sae-Gwang,Seo, Su-Kil,Lee, Soo-Woong,Lee, Chang Min,Yea, Sung Su,Choi, Yung Hyun,Choi, Il-Whan Elsevier 2008 BIOMEDICINE AND PHARMACOTHERAPY Vol.62 No.5

<P><B>Abstract</B></P><P><I>Ecklonia cava</I> (EC) is a brown alga that evidences radical scavenging activity, bactericidal activity, tyrosinase inhibitory activity, and protease inhibitory activity. However, its anti-allergic effects remain poorly understood. In the current study, we attempted to determine whether pretreatment with EC induces a significant inhibition of asthmatic reactions in a mouse asthma model. Mice sensitized and challenged with ovalbumin (OVA) evidenced typical asthmatic reactions, as follows: an increase in the number of eosinophils in bronchoalveolar lavage fluid; a marked influx of inflammatory cells into the lung around blood vessels and airways, and airway luminal narrowing; the development of airway hyperresponsiveness; the detection of tumor necrosis factor-alpha (TNF-α) and Th2 cytokines, including IL-4 and IL-5 in the bronchoalveolar lavage (BAL) fluid; and the detection of allergen-specific immunoglobulin E (IgE) in the serum. However, the administration of EC extract prior to the final airway OVA challenge resulted in a significant inhibition of all asthmatic reactions. We also demonstrated that EC extracts treatment resulted in significant reductions on matrix metalloproteinase-9 (MMP-9) and Suppressor of cytokine signaling-3 (SOCS-3) expression and a reduction in the increased eosinophil peroxidase (EPO) activity. The treatment of animals with EC extracts resulted in a significant reduction in the concentrations of the Th2 cytokine (IL-4 and IL-5) in the airways, without any concomitant increase in the concentration of Th1 cytokines. These findings indicate that EC extracts may prove useful as an adjuvant therapy for allergic airway reactions via the inhibition of the Th2 response. Accordingly, this study may provide evidence that EC extract performs a critical function in the amelioration of the pathogenetic process of asthma in mice.</P>

일반적인 버섯 배지(미강 10%), 폐 한방슬러지를 10% 첨가한 배지, 그리고 미강 10%와 폐 한방슬러지 10%를 혼합한 배지에서 재배한 팽이버섯의 면역기능 강화효과를 알아보기 위해 물 추출물과 에탄올 추출물로 분리하여 실험하였다. 그 중 폐 한방슬러지 10%를 첨가한 배지에서 재배한 팽이버섯의 에탄올 추출물을 첨가하였을 때, 비장세포의 증식을 크게 유도하였으며 또한 IL-6, TNF-α, IFN-γ 분비를 유도하였다. 그리고 B세포의 증식반응과 면역글로불린 생산도 증가하였으며, 대식세포주의 일산화질소 분비와 IL-6, TNF-α, GM-CSF 생산도 증가하였다. 또한 복수암 유발 종양세포를 이용한 항종양 효과를 측정 한 결과 대조군의 평균 21.1일보다 실험군은 24.5일로 16.1%의 수명 연장효과가 나타났다. 따라서 폐 한방슬러지를 이용하면 수입에 의존하고 있는 버섯 재배 배지 원료를 절약할 수 있으며 면역세포조절 기능을 강화시키는 기능성 버섯을 얻을 수 있다고 생각한다. The objective of the current study was to determine the effects of the extracts isolated from the fruit body of Flammulina velutipes cultivated with oriental herbal plants on mouse splenocytes, B cells, and macrophages in vitro. The ethanol extracts B (EEB) directly induced the proliferation of spleen cells in a dose-dependent manner and increased IL-6, TNF-α, and IFN-γ synthesis. The EEB also increased the proliferation of B cells in a dose-dependent manner. The production of immunoglobulin M, G1, G2a, G2b, and IgG3 in the presence of the EEB increased progressively in the culture supernatant. When the EEB were used in macrophage cell line (RAW264.7) stimulation, there was a marked induction of NO synthesis in a dose-dependent manner and an increased IL-6, TNF-α, and GM-CSF synthesis. Intraperitoneal injection with EBB showed life prolongation effect of 16.1% in mice previously inoculated with sarcoma-180, respectively. These results suggest that the capacity of the EEB isolated from the fruit body of Flammulina velutipes cultivated with oriental herbal plants seems to act as a potent immunomodulator causing augmentation of immune cell activity, and with the absence of notable side-effects, Flammulina velutipes EEB could be used as a biological response modifier having possible therapeutic effects against immunological disorders. This study also showed that functional components of Flammulina velutipes were possibly improved by incorporating oriental herbal plants in a growth medium.

Lonicerae Flos has antibacterial effects against Staphylococcus aureus, streptococci, pneumococci, Bacillus dysenterii, Salmonella typhi, and paratyphoid. It is an antiviral agent. The herb has a cytoprotective effect against $CCl_{4}-induced$ hepatic injury. It has antilipemic action, interfering with lipid absorption from the gut. Nowadays this herb is used mainly in the treatment of upper respiratory infections, such as tonsillitis and acute laryngitis. It is also used in the treatment of skin suppurations, such as carbuncles, and to treat viral conjunctivitis, influenza, pneumonia, and mastitis. Lonicerae Flos is dried flower buds of Lonicera japonica, L. hypoglauca, L. confusa, or L. dasystyla. But, for the most part, we use whole plant of Lonicera japonica, as a flower bud of it. And, little is known of the original copy of effects of whole plant, except for the 'Bon-Cho-Gang-Mok', which is written the effects of flower of Lonicera japonica are equal to effects of leaves and branch of it. The present study was conducted to evaluate the effect of flower and whole plant of Lonicera japonica on the regulatory mechanism of cytokines, inducible nitric oxide synthase (iNOS) and cyclooxygenase (COX-2) for the immunological activities in Raw 264.7 cells. In Raw 264.7 cells stimulated with lipopolysaccharide (LPS) to mimic inflammation, flower and whole plant of Lonicera japonica water extracts inhibited nitric oxide production in a dose-dependent manner and abrogated iNOS and COX-2. Flower and whole plant of Lonicera japonica water extract did not affect on cell viability. To investigate the mechanism by which flower and whole plant of Lonicera japonica water extract inhibits iNOS and COX-2 gene expression, we examined the on phosphorylation of inhibitor ${\kappa}B{\alpha}$ and assessed production of $TNF-{\alpha}$, $interleukin-1{\beta}$ $(IL-1{\beta})$ and interleukin-6 (IL-6). Results provided evidence that flower and whole plant of Lonicera japonica inhibited the production of $IL-1{\beta}$, IL-6 and activated the phosphorylation of inhibitor ${\kappa}B{\alpha}$ in Raw 264.7 cells activated with LPS. These findings suggest that flower and whole plant of Lonicera japonica can produce anti-inflammatory effect, which may play a role in adjunctive therapy in Gram-negative bacterial infections, respectively.
