The purpose of the present investigation was to compare similarities and differences in immune response among Echinacea species, which are commonly used to treat upper respiratory infections. The investigation involved two components: acquisition of immunomodulatory data reported here for the first time, and combined phenetic analysis of these data along with previous reports. Experimental data were obtained by stimulating human PBMC in vitro with extracts from Echinacea spp. and assaying production of three cytokines (interleukin-1β [IL-1β], interleukin-2 [IL-2], and tumor necrosis factor-α [TNF-α]). Phenetic analyses were employed to compare responses across the entire data set, including UPGMA (Unweighted Pair Group Method with Arithmetic Mean) and neighbor-joining methods. In the immune experiments conducted for this investigation, E. angustifolia, E. paradoxa, E. purpurea, E. simulata, and E. tennesseensis extracts significantly augmented IL-1 β and TNF-α production, whereas no extracts significantly modulated IL-2. All phenetic methods produced similar dendrograms, revealing two species pairs (E. angustifolia + E. simulata and E. pallida + E.sanguinea) where both species cluster tightly and have similar immune-response profiles. These two species-pairs are maximally dissimilar from each other. The remaining species (E. paradoxa, E. purpurea, and E. tennesseensis) occupy intermediate positions in the dendrogram. Our results suggest that Echinacea spp. act heterogeneously on immune function. The utility of these data for science and industry is discussed.

基于免疫调节特性的七种紫锥花属物种的表型比较。

本研究的目的是比较通常用于治疗上呼吸道感染的紫锥花属物种之间免疫反应的异同。调查涉及两个部分:首次获得此处报告的免疫调节数据,以及对这些数据与先前报告的综合表型分析。实验数据是通过用紫锥菊属植物的提取物在体外刺激人 PBMC 获得的。并测定三种细胞因子(白介素-1β [IL-1β]、白介素-2 [IL-2] 和肿瘤坏死因子-α [TNF-α])的产生。表型分析用于比较整个数据集的响应,包括 UPGMA(具有算术平均值的未加权对组方法)和相邻连接方法。在为本研究进行的免疫实验中,E. angustifolia、E. paradoxa、E. purpurea、E. simulata 和 E. tennesseensis 提取物显着增加了 IL-1 β 和 TNF-α 的产生,而没有提取物显着调节 IL-2。所有表型方法产生了相似的树状图,揭示了两个物种对(E. angustifolia + E. simulata 和 E. pallida + E.sanguinea),其中两个物种紧密聚集并具有相似的免疫反应谱。这两个物种对彼此最大程度不同。其余物种(E. paradoxa、E. purpurea 和 E. tennesseensis)在树状图中占据中间位置。我们的结果表明紫锥菊属。对免疫功能有异质性作用。讨论了这些数据对科学和工业的效用。田纳西提取物显着增加 IL-1 β 和 TNF-α 的产生,而没有提取物显着调节 IL-2。所有表型方法产生了相似的树状图,揭示了两个物种对(E. angustifolia + E. simulata 和 E. pallida + E.sanguinea),其中两个物种紧密聚集并具有相似的免疫反应谱。这两个物种对彼此最大程度不同。其余物种(E. paradoxa、E. purpurea 和 E. tennesseensis)在树状图中占据中间位置。我们的结果表明紫锥菊属。对免疫功能有异质性作用。讨论了这些数据对科学和工业的效用。田纳西提取物显着增加 IL-1 β 和 TNF-α 的产生,而没有提取物显着调节 IL-2。所有表型方法产生了相似的树状图,揭示了两个物种对(E. angustifolia + E. simulata 和 E. pallida + E.sanguinea),其中两个物种紧密聚集并具有相似的免疫反应谱。这两个物种对彼此最大程度不同。其余物种(E. paradoxa、E. purpurea 和 E. tennesseensis)在树状图中占据中间位置。我们的结果表明紫锥菊属。对免疫功能有异质性作用。讨论了这些数据对科学和工业的效用。sanguinea),其中两个物种紧密聚集并具有相似的免疫反应谱。这两个物种对彼此最大程度不同。其余物种(E. paradoxa、E. purpurea 和 E. tennesseensis)在树状图中占据中间位置。我们的结果表明紫锥菊属。对免疫功能有异质性作用。讨论了这些数据对科学和工业的效用。sanguinea),其中两个物种紧密聚集并具有相似的免疫反应谱。这两个物种对彼此最大程度不同。其余物种(E. paradoxa、E. purpurea 和 E. tennesseensis)在树状图中占据中间位置。我们的结果表明紫锥菊属。对免疫功能有异质性作用。讨论了这些数据对科学和工业的效用。
