  • $80^{\circ}C$에서 30% 주정으로 추출된 소엽추출물 분말의 로즈마린산 함량은 12.3 mg/g이었으며, 소엽 30% 주정추출물분말(PF-E30)은 생쥐모델 실험에서 ant-DNP IgE으로 활성화된 local allergy 반응과 compound 48/80으로 유도된 mast cell-mediated immediatetype allergy 반응에 대한 억제 효과를 나타내었다. 더욱이, PFE30(0.1-0.5 mg/kg BW)의 투여는 혈장 히스타민 수준을 유의성있게 감소시켰으며, compound 48/80 또는 anti-DNP IgE으로 활성화된 복막 비만세포로부터 히스타민 방출을 억제하였다. 특히 PFE30는 antigen-induced IgE 의 생산을 농도 의존적으로 억제하였다. 이런 결과는 소엽 주정추출물이 in vivo 및 in vitro 실험에서 mast cell-mediated immediate-type allergy 반응을 저해한다는 것을 제시한다. 소엽 주정추출물이 알레르기 반응을 억제하는 기능성 식품 소재로서의 개발을 위해서는 mast cell mediated-type allergy 반응에 대한 보다 많은 연구가 필요할 것이다.

  • Allergy 질환은 지난 십여년 동안 개발도상국을 포함해서 전 세계적으로 증가하고 있다. Allergy 염증 반응은 수지상 세포와 같은 항원제시 세포에 의한 allergy 항원섭취를 시작으로 하여 Th2 면역 반응에 의해서 일어난다. 장내 미생물은 신체의 대사나 생리적 기능을 조절하고, 생애 초기의 면역 체계 성숙과 일생 동안 면역 체계 항상성 및 상피세포 총체성에 기여한다. Bifidobacteria는 Th1/Th2 balance에 strain-specific 한 면역 자극 특성을 가지며, TSLP와 IgE 발현을 억제 시키고 Flg과 FoxP3 발현을 촉진 시켜 allergy를 완화시킨다. 또한 Unmethylated CpG motif ODN은 B 세포와 수지상 세포의 TLR9에 의해 인식 되어 선천성과 적응성 면역 반응을 유도하고, Clostridium butyricum에 의해서 생산된 butyrate는 수지상 세포의 anti-inflammatory 유전자의 발현을 유도하기 위해 GPR109a signaling pathway를 활성화시키고, GPR43 활성화를 통하여 tTreg 세포 proliferation을 직접 자극하거나 HADC 활성을 억제시켜 Foxp3 gene intronic enhancer의 histone H3 acetylation을 통해 naive $CD4^+$ T 세포를 pTreg 세포로 분화시킨다.

  • Background and Objective : Atractylodes japonica (AJ) is a commonly-used herbal medicine in Asian countries such as Korea, China and Japan. The present study was designated to evaluate the direct effects of AJ on helper T cell activities and on Th1/Th2 lineage development in vitro. Materials and Methods : Spleen cells from 8-week BALB/c mice were cultured in CR extracts containing medium without activation for 24 hours and with activation for 48 hours. CD4+ T cells were isolated and analyzed for mRNA expression levels of INF-$\gamma$, IL-4, T-bet and GATA-3 by RT-PCR and secretion cytokines levels of INF-$\gamma$, IL-2, IL-4, IL-5 and IL-10 by ELISA. Results : The results demonstrated that AJ had no mitogenic effects on unstimulated CD4+ T cells, but augmented CD4+T-cell proliferation upon activation with anti-CD3/anti-CD28 antibodies in a dose-dependent manner. AJ treatment significantly increased CD4+ T cell population and IFN-$\gamma$ expression was significantly enhanced, while IL-4 expression significantly decreased. In addition, in vitro Th1/Th2 polarization experiments revealed that AJ enhanced IFN-$\gamma$ secretion in Th1 cells, but reduced the IL-4 in Th2 cells in dose-dependent manner. Conclusion : These results suggest that AJ treatment could be a desirable alternative therapy for the prevention or correction of Th2 dominant pathological disorders, such as allergy and asthma.

  • Objectives : Atopic dermatitis (AD) is a chronic inflammatory skin disease characterized by eczematous inflammtion of the skin. The chestnut inner shell extracts (CI) has been used as a cosmetic material for a long time in Korea. However, the precise anti-allergy effects of CI have yet to be clearly elucidated. In this study, we attempted to evaluate the effect of CI on mast cell-mediated allergy inflammation. Methods : To find the anti-allergy and inflammatory effect of CI, we investigated the inhibitory effect of CI on the production of inflammatory mediators using by enzyme-linked immunosorbent assay in phorbol 12-myristate 13-acetate (PMA) plus calcium ionophore (A23187) stimulated-human mast cell (HMC-1). Results : In this study, we found that CI did not show cytotoxic effect at up to 10 ug/ml on HMC-1. CI inhibited the production of tumor necrosis factor (TNF)-${\alpha}$, interleukin (IL)-6 and IL-8 in stimulated HMC-1. Maximal rate of TNF-${\alpha}$, IL-6 and IL-8 inhibition by CI (10 ug/ml) were about 47.6%, 44.1% and 22.5% respectively. In addition, we showed that Fr.3 isolated from n-Butyl alcohol layer of CI attenuated the production of TNF-${\alpha}$, IL-6 and IL-8 in HMC-1. Conclusion : Taken together, the findings of this study provide us with a novel insight action of CI as a potential molecule for use in the treatment of allergic inflammation diseases.

  • Egg allergy has been raised as the most prevalent food hypersensitivity in children. Ovalbumin (OVA), which is one of the major egg allergens, is the major protein in egg white. Isoliquiritigenin (ILG) is an active component present in licorice and has been used to treat many chronic diseases for many years. In this study, we present biochemical evidence that ILG inhibits OVA-induced nuclear factor-${\kappa}B$ (NF-${\kappa}B$) activation. ILG also inhibits OVA-induced cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS) expression. These data suggest that ILG has anti-allergy effects.

  • Asthma is a chronic airway inflammatory disease characterized by reversible airway obstruction and airway hyperreactivity to various environmental stimuli, leading to recurrent cough, dyspnea, and wheezing episodes. Regarding inflammatory mechanisms, type 2/eosinophilic inflammation along with activated mast cells is the major one; however, diverse mechanisms, including structural cells-derived and non-type 2/neutrophilic inflammations are involved, presenting heterogenous phenotypes. Although most asthmatic patients could be properly controlled by the guided treatment, patients with severe asthma (SA; classified as a treatment-refractory group) suffer from uncontrolled symptoms with frequent asthma exacerbations even on regular anti-inflammatory medications, raising needs for additional controllers, including biologics that target specific molecules found in asthmatic airway, and achieving the precision medicine for asthma. This review summarizes the immunologic basis of airway inflammatory mechanisms and current biologics for SA in order to address unmet needs for future targets.

  • Aspirin-intolerant asthma (AIA) is characterized by severe asthmatic attack after ingestion of aspirin and/or non-steroidal anti-inflammatory drugs. In this study, we investigated the relationship between Prostaglandin E2 receptor (PTGER) gene family polymorphisms and AIA in 243 AIA patients and 919 aspirin-tolerant asthma (ATA) controls of Korean ethnicity in two separate study cohorts. After genotyping 120 SNPs of the PTGER gene family for the $1^{st}$ cohort study, four SNPs in PTGER1, ten in PTGER3, six in PTGER3, and a haplotype of PTGER2 showed association signals with decreased or increased risk of AIA. Among the positively associated SNPs, one in PTGER1 and four in PTGER3 were analyzed in the $2^{nd}$ cohort study. The results show that rs7543182 and rs959 in PTGER3 retained their effect, although no statistical significance was retained in the $2^{nd}$ cohort study. Our findings provide further evidence that polymorphisms in PTGER3 might play a significant role in aspirin hypersensitivity among Korean asthmatics.

  • Cimicifuga racemosa (Black cohosh) has been used as therapeutics for pain and inflammation in Korean folk medicine. The potential effects of cimicifuga racemosa extract on mast cell dependent allergy reaction, however, have not been well elucidated yet. In the present study, we investigated the effect of cimicifuga racemosa extract on the allergy reaction using mast cell dependent in vivo and in vitro models. The oral administration of cimicifuga racemosa extract showed inhibitory potential on the compound 48/80 induced active systemic anaphylactic shock. cimicifuga racemosa extract also significantly inhibited the anti DNP IgE induced passive cutaneous anaphylaxis (PCA) reaction and acetic acid induced vascular permeability. In addition, cimicifuga racemosa extract inhibited the beta hexosaminidase release and TNF alpha and IL 4 mRNA induction by DNP HSA in rat leukemia mast cells, RBL 2H3. but cimicifuga racemosa extract didn't affected to RBL 2H3 cell viability. These results demonstrated that cimicifuga racemosa extract has an anti allergic potential and it may be due to the inhibition of histamine release and cytokine gene expression in the mast cells.
