β-D-glucans are diverse polysaccharides derived from plant cell walls, fungi and bacteria. β-D-glucans are composed of D-glucose monomers linked by (1-3) β-glycosidic bonds with varying amounts of (1-6) or (1-4) linked side chains that bind cell surface receptors ultimately triggering changes in intracellular pathways and gene transcription. β-D-glucans have anti-viral, immunomodulatory and anti-cancer activities. This article reviews the current identity and putative function of genes regulated by β-glucans purified from various sources in human cancer and immune cells and in murine dendritic, macrophage cells and lungs. β-D-glucans increase the expression of numerous cytokines and immunomodulatory factors and their receptors in dendritic cells. Pathways and transcription factors involved in the cellular responses to β-glucans are summarized.
β-D-葡聚糖是从植物细胞壁、真菌和细菌中提取的多种多糖。β-D-葡聚糖由通过(1-3)β-糖苷键连接的D-葡萄糖单体和不同量的(1-6)或(1-4)连接的侧链组成,这些侧链结合细胞表面受体,最终触发细胞内途径和基因转录的变化。β-D-葡聚糖具有抗病毒、免疫调节和抗癌活性。本文综述了从不同来源纯化的β-葡聚糖调节基因在人类癌症和免疫细胞以及小鼠树突状细胞、巨噬细胞和肺中的当前身份和推定功能。β-D-葡聚糖增加树突状细胞中多种细胞因子和免疫调节因子及其受体的表达。综述了参与细胞对β-葡聚糖反应的途径和转录因子。

In the recent decades, several health-promoting features have been ascribed to β-glucans. Biological properties such as anti-cancer, anti-inflammatory and immune-modulating activity have been claimed for these polysaccharides. Moreover, when β-glucans were used in association with probiotic bacteria, prebiotic effects have been demonstrated, due to their ability to enhance growth, metabolism and/or beneficial activities of probiotics. This review shall present an overview of those studies, which have documented the diverse health-benefits of β-glucans and their association with probiotics.
近几十年来,β-葡聚糖具有多种促进健康的特性。这些多糖具有抗癌、抗炎和免疫调节活性等生物学特性。此外,当β-葡聚糖与益生菌联合使用时,由于它们能够增强益生菌的生长、代谢和/或有益活性,因此已经证明了益生元的作用。本综述将概述这些研究,这些研究记录了β-葡聚糖的多种健康益处及其与益生菌的关系。

β-Glucan in Allergies β-葡聚糖在过敏中的作用
Pub Date : 2017-03-30 DOI: 10.3844/AJISP.2017.73.80
Sima Petr, V. Vaclav
Multiple effects of β-glucan are well established. Together with the effects on antibacterial and anticancer immunity, glucan has been shown to stimulate bone marrow cells, lower cholesterol and to protects against stress and some kinds of poisoning. However, despite literally thousands of papers describing biological effects of β-glucan, only limited attention has been focused on the role of β-glucan in allergic reactions. Our review is focused on evaluating the current knowledge of the possible role of β-glucan in allergic reactions. Most of published studies concur that based on the improved Th1/Th2 balance, β-glucan showed a potential for development as an adjunct to the standard treatment of in patients with allergies.
β-葡聚糖的多种作用已得到充分证实。葡聚糖与抗菌和抗癌免疫的作用一起,已被证明可以刺激骨髓细胞,降低胆固醇,防止压力和某些中毒。然而,尽管有数千篇论文描述了β-葡聚糖的生物学作用,但对β-葡聚糖在过敏反应中的作用的关注有限。我们的综述重点是评估目前对β-葡聚糖在过敏反应中可能作用的认识。大多数已发表的研究一致认为,基于Th1/Th2平衡的改善,β-葡聚糖显示出作为过敏患者标准治疗的辅助药物的发展潜力。

Sixty-six children were supplemented with beta glucan and dietary nucleotides, another 63 children served as negative control. We evaluated the effects of these supplements on several aspects of secretory immunity such as levels of secretory IgA (SIgA), albumin and SIgA/albumin ratio. In addition, in order to monitor effects of physical challenges and compensatory treatments on stress and reparation of immunity, we measured levels of salivary cortisol. We found significant effects of supplementation with beta glucan on secretory IgA in children with increased physical challenge. To fully explain these findings, we will need to add additional indicators of stress and salivary immunity.
66名儿童补充了β-葡聚糖和膳食核苷酸,另有63名儿童作为阴性对照。我们评估了这些补充剂对分泌性免疫的几个方面的影响,如分泌性IgA(SIgA)水平、白蛋白和SIgA/白蛋白比率。此外,为了监测身体挑战和补偿治疗对压力和免疫力恢复的影响,我们测量了唾液皮质醇水平。我们发现,补充β-葡聚糖对身体挑战增加的儿童分泌型IgA有显著影响。为了充分解释这些发现,我们需要添加额外的压力和唾液免疫指标。

β-Glucans are biomacromolecules of industrial interest for its biological and technological properties, including ability to modify the rheology of food systems and different biological functionalities. In this study, lasiodiplodan an exocellular polysaccharide of the (1→6)-β-D-glucan type produced by the fungus Lasiodiplodia theobromae MMPI was obtained in a bench-scale bioreactor operated in discontinuous mode. Lasiodiplodan produced was derivatized by carboxymethylation and characterized by Fourier Transform Infrared spectroscopy (FT-IR), Thermogravimetry and Differential Thermal Analysis (TG-DTA), X-Ray Diffraction (XRD), scan electron microscopy (SEM) and their antioxidant and antimicrobial potential also was assessed. Two strong absorption bands in the regions of 1422 to 1598 cm-1, resulting from symmetric and asymmetric stretching vibrations of the -COO- group respectively, were observed in the FT-IR spectrum of the derivatized sample and indicated the carboxymethylation of the macromolecule. TG-DTA curves indicated that native (LAS-N) and carboxymethylated (LAS-C) lasiodiplodan did not suffer significant changes in relation to the heating rates. Native and carboxymethylated lasiodiplodan demonstrated high thermal stability considering the usual standards of the pharmaceutical industry. The final temperature of thermal decomposition increased when the heating rate was increased and less number of steps for thermal decomposition was observed when air was substituted for nitrogen. XRD analysis showed the LAS-N and LAS-C have no crystalline structure, but carboxymethylation led to the arising of regions with certain molecular orientation in biopolymer structure. SEM analysis showed that the carboxymethylation promoted changes in biopolymer macrostructure, including breaking of the polymeric structure and arising of bubbles on the surface area. Carboxymethylation contributed to improving the polysaccharide's antioxidant capacity and LAS-C demonstrated antimicrobial activity against Candida tropicalis.
β-葡聚糖是一种具有工业价值的生物大分子,其生物学和技术特性,包括改变食品系统流变学和不同的生物功能的能力。本研究在不连续模式下的实验反应器中获得了由真菌Lasiodiplodia theobromae MMPI产生的(1→6)-β- d -葡聚糖型的细胞外多糖lasiodiplodan。采用羧甲基化衍生法对所制得的龙脑进行了表征,并采用傅里叶变换红外光谱(FT-IR)、热重和差热分析(TG-DTA)、x射线衍射(XRD)、扫描电镜(SEM)对其进行了表征,并对其抗氧化和抗菌性能进行了评价。在衍生化样品的FT-IR光谱中观察到1422 ~ 1598 cm-1区域分别由- coo -基团的对称和不对称拉伸振动产生的两条强吸收带,表明大分子发生了羧甲基化。TG-DTA曲线显示,原生(LAS-N)和羧甲基化(LAS-C)的lasiodiploda随升温速率的变化不显著。考虑到制药工业的通常标准,天然和羧甲基化的雷公龙表现出很高的热稳定性。随着升温速率的增加,热分解的最终温度升高,以空气代替氮气时,热分解的步骤减少。XRD分析表明,LAS-N和LAS-C没有结晶结构,但羧基甲基化导致生物聚合物结构中出现具有一定分子取向的区域。SEM分析表明,羧甲基化促进了生物聚合物宏观结构的变化,包括聚合物结构的断裂和表面气泡的产生。羧甲基化有助于提高多糖的抗氧化能力,LAS-C对热带念珠菌具有抗菌活性。

A public health issue, Diabetes mellitus, affects millions of people around the globe. Ingestion of foods with a low glycemic index - fiber-rich meals-such as beta-glucans, is increasing as an important alternative for diabetes control. These compounds act reducing parameters such as blood glucose, cholesterol and triglycerides, by decreasing the absorption of glucose and lipids by enterocytes and eventually promote weight loss. Beta-glucans are also described as immunomodulatory agents by stimulating phagocytosis and the production of pro-inflammatory cytokines, increasing host resistance to viral, bacterial, fungal and parasitic infections; or production of anti-inflammatory cytokinesto return homeostasis after an immune response. Besides, some studies are also evidencing anti-tumoral activity. Beta-glucans main effect depends on their origin-yeast, plants or bacteria. Reports of collateral effects and/or toxicity associated with the use of beta-glucans are rare, which contribute to consider this compound for inclusion in a range of therapies. This review aims to evaluate the most different effects of beta-glucans in metabolic and immune systems, discussing its advantages and limitations.
糖尿病是一个影响全球数百万人的公共卫生问题。摄入低血糖指数食物——富含纤维的食物,如β-葡聚糖,正日益成为控制糖尿病的重要替代品。这些化合物通过减少肠细胞对葡萄糖和脂质的吸收,降低血糖、胆固醇和甘油三酯等参数,最终促进减肥。β-葡聚糖也被描述为免疫调节剂,通过刺激吞噬作用和促炎细胞因子的产生,增加宿主对病毒、细菌、真菌和寄生虫感染的抵抗力;或产生抗炎胞质分裂以在免疫反应后恢复稳态。此外,一些研究也证明了抗肿瘤活性。β-葡聚糖的主要作用取决于其来源酵母、植物或细菌。与使用β-葡聚糖相关的副作用和/或毒性的报告很少,这有助于考虑将该化合物纳入一系列治疗中。这篇综述旨在评估β-葡聚糖在代谢和免疫系统中最不同的作用,讨论其优点和局限性。

Connection between Endometriosis and Vitamin D – True or False? 子宫内膜异位症与维生素D之间的关系——对还是错?

Endometriosis is a serious health problem characterized by the persistence and growth of vascularized tissue at various ectopic sites such as ovaries, bowel, or bladder. Despite decades of intensive research, we are not making significant progress toward the etiology or treatment of this disease. The question of risk factor is similarly unclear, with one possible factor being diet-particularly the intake of vitamin D. In addition, as endometriosis has some similarities and clear connections to cancer, where vitamin D is heavily studied, this relation started to be a subject of intensive research in this field, too. The overall aim of this study is to review possible links between vitamin D intake and endometriosis.
子宫内膜异位症是一个严重的健康问题,其特征是卵巢、肠道或膀胱等异位部位血管化组织的持续存在和生长。尽管经过几十年的深入研究,我们在这种疾病的病因或治疗方面没有取得重大进展。风险因素的问题同样不清楚,一个可能的因素是饮食,尤其是维生素D的摄入。此外,由于子宫内膜异位症与癌症有一些相似之处和明确的联系,维生素D在癌症得到了大量研究,这种关系也开始成为该领域深入研究的主题。本研究的总体目的是审查维生素D摄入与子宫内膜异位症之间的可能联系。

In addition, as endometriosis has some similarities and clear connections to cancer, where vitamin D is heavily studied, this relation started to be a subject of intensive research in this field, too. The overall aim of this study is to review possible links between vitamin D intake and endometriosis.","PeriodicalId":88361,"journal":{"name":"American journal of immunology","volume":"13 1","pages":"127-130"},"PeriodicalIF":0.0,"publicationDate":"2017-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.3844/AJISP.2017.127.130","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49178450","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we describe the Ruggiero-Klinghardt (RK) Protocol that is based on integration of Autonomic Response Testing (ART) with diagnostic ultrasonography and on application of therapeutic ultrasounds; the latter are used as a provocation tool and as an instrument to optimize drug uptake and utilization in specific areas of the body. This protocol consists of a precise sequence of diagnostic and therapeutic procedures with the ultimate goal of improving sensitivity and specificity of diagnosis at the same time evaluating and optimizing efficacy of treatments in chronic conditions including, but not limited to, persistent Lyme disease. The RK Protocol represents a paradigm shift in diagnostics and therapeutics: Thus, compartmentalized microbes, transformed cells, toxins and metabolites could be detected using a safe and non-invasive method. In addition, the RK Protocol allows optimization of efficacy of drugs and other therapeutic interventions. Although the RK Protocol was initially developed for persistent Lyme disease, it shows significant potential in conditions ranging from cancer to neurodegenerative diseases and autism. In oncology, the RK Protocol may serve to facilitate early diagnosis and to increase sensitivity of cancer cells to the killing effects of a variety of remedies ranging from conventional radio- and chemotherapy to more recent forms of immunotherapy. Thus, the 1st goal of the RK Protocol is diagnostic: That is, to make pathogens, toxins, transformed cells and cells infected by viruses that are inaccessible to conventional diagnostic and therapeutic tools, "visible" to the therapist who can detect them with laboratory methods and deal with them with appropriate interventions; and also to make them "visible" to the immune system that can fight them in a physiological manner. The 2nd goal is to optimize drug uptake and utilization in the organs and tissues studied and targeted with these procedures.
在这里,我们描述了Ruggiero Klinghardt(RK)方案,该方案基于自主反应测试(ART)与诊断超声的结合以及治疗超声的应用;后者被用作激发工具和优化身体特定区域的药物摄取和利用的工具。该方案由一系列精确的诊断和治疗程序组成,最终目标是提高诊断的敏感性和特异性,同时评估和优化慢性病的治疗效果,包括但不限于持续性莱姆病。RK协议代表了诊断和治疗的范式转变:因此,可以使用安全和非侵入性的方法检测分隔的微生物、转化细胞、毒素和代谢物。此外,RK协议允许优化药物和其他治疗干预措施的疗效。尽管RK方案最初是针对持续性莱姆病开发的,但它在从癌症到神经退行性疾病和自闭症等疾病中显示出巨大的潜力。在肿瘤学中,RK方案可能有助于促进早期诊断,并提高癌症细胞对从传统放射和化疗到更新形式的免疫疗法等多种疗法的杀伤作用的敏感性。因此,RK协议的第一个目标是诊断:即使病原体、毒素、转化细胞和被病毒感染的细胞“可见”于治疗师,治疗师可以用实验室方法检测它们,并通过适当的干预措施处理它们;并使它们对免疫系统“可见”,免疫系统可以以生理方式对抗它们。第二个目标是优化这些程序所研究和靶向的器官和组织中的药物摄取和利用。
