摘要

黄精是一种传统的中药材和食品同源物质,通常与黄酒加工后使用。然而,其主要活性成分多糖在葡萄酒加工后的研究较少。本研究旨在探讨酒后黄精多糖对免疫抑制小鼠功能的影响及其机制。采用水提醇沉法提取黄酒黄精多糖。采用环磷酰胺(CTX)建立BALB/c小鼠免疫抑制动物模型。采用酶联免疫吸附法、流式细胞术等技术检测YWPP多糖白细胞介素2、干扰素γ、免疫球蛋白A、免疫球蛋白M、T淋巴细胞亚群等指标的免疫调节作用。为了研究多糖的免疫调节机制,采用16s rDNA测序和气相色谱/质谱(GC/MS)分析了肠道菌群组成、多样性和短链脂肪酸(SCFAs)含量的变化。采用Spearman法分析肠道菌群与各免疫指标及scfa的相关性。结果表明,YWPP多糖能显著恢复免疫抑制小鼠的体重,改善脾脏和胸腺功能,调节外周血细胞值。YWPP多糖还能有效促进免疫抑制小鼠的白细胞介素2、干扰素γ、免疫球蛋白A和免疫球蛋白M,调节免疫相关指标的表达。YWPP多糖促进了scfa的产生,显著调节了norank_f_ norank_o_ rf39、Rikenellaceae_RC9_gut_group、norank_f_ UCG-010和norank_f_ norank_o_ clostridia_ucg -014的相对丰度;逆转ctx诱导的小鼠肠道微生物群代谢异常;把它们标准化。Spearman相关分析显示,肠道菌群相对丰度与各免疫指标和scfa呈显著相关。综上所述,YWPP多糖可以改善ctx诱导的免疫功能低下小鼠的免疫功能,促进小鼠细胞因子上调和免疫相关有益菌的相对丰度,调节肠道菌群,从而调节宿主免疫。本研究结果将为YWPP多糖的实际应用、保健品开发及多元化产品开发提供理论依据。

Effects of wine processed Polygonatum polysaccharides on immunomodulatory effects and intestinal microecology in mice
Polygonatum sibiricum is a traditional Chinese medicinal and food homologous substance, usually used after processing with yellow wine. However, its main active ingredient, polysaccharide, has been less studied after wine processing. This study aimed to investigate the effect of Polygonatum polysaccharides after wine processing on the function of immunosuppressed mice and its related mechanisms. The yellow wine processed Polygonatum (YWPP) polysaccharides were extracted by the water extraction alcohol precipitation method. BALB/c mice were used to establish the immunosuppressive animal model with cyclophosphamide (CTX). The immunomodulatory effect of the YWPP polysaccharides Interleukin 2, interferon γ, immunoglobulin A, Immunoglobulin M, T lymphocyte subsets, and other indexes were detected by enzyme-linked immunosorbent assay, flow cytometry, and other technologies. To study the mechanism of immunomodulation of polysaccharides, 16s rDNA sequencing and Gas Chromatography/Mass Spectrometry (GC/MS) were used to analyze the changes of intestinal microbiota composition, diversity, and the content of short-chain fatty acids (SCFAs). The Spearman method was used to analyze the correlation between gut microbiota and various immune indexes and SCFAs. The results showed that the YWPP polysaccharides could significantly restore the body weight of immunosuppressed mice, improve the spleen and thymus, and regulate peripheral blood cell values. The YWPP polysaccharides can also effectively promote Interleukin 2, interferon γ, immunoglobulin A, and immunoglobulin M in immunosuppressed mice and regulate the expression of immune-related indexes. The YWPP polysaccharides promoted the production of SCFAs, significantly regulated the relative abundance of norank_f__norank_o__RF39, Rikenellaceae_RC9_gut_group, norank_f__ UCG-010, and norank_f__norank_o__Clostridia_UCG-014; reversed CTX-induced metabolic abnormalities of mouse gut microbiota; and normalized them. Spearman correlation analysis showed that the relative abundance of gut microbiota was significantly correlated with various immune indices and SCFAs. In conclusion, the YWPP polysaccharides can improve the immune function of CTX-induced immunocompromised mice, promote cytokine upregulation and the relative abundance of immune-related beneficial bacteria in mice, and regulate the gut microbiota, thereby regulating host immunity. The results of this study will provide a theoretical basis for the practical application of the YWPP polysaccharides, health product development, and diversified product development.
