摘要: 本研究利用植物乳植杆菌HM6008发酵鱼腥草制备鱼腥草发酵多糖(记为FHCTP),并进行理化性质测定,同时采用大鼠嗜碱性白血病细胞(rat basophilic leukemia,RBL)-2H3评估FHCTP的抗过敏活性。结果表明,发酵提高了FHCTP中的甘露糖与硫酸根比例,且FHCTP的粒径较未发酵鱼腥草多糖(HCTP)减小26.67%,并提了高多糖溶液的稳定性。通过RBL-2H3细胞实验发现,FHCTP的脱颗粒抑制率((82.79±5.19)%)显著高于HCTP((53.75±1.95)%),其干预后细胞免疫球蛋白E Fc段受体(fragment crystallizable epsilon receptor,FcεR)I表达量显著下调,其平均荧光强度由2 458.00±7.50降至1 495.00±28.50,并且FHCTP与HCTP均能有效抑制细胞骨架蛋白异构和胞内钙离子浓度升高;此外,小鼠被动皮肤过敏反应中,FHCTP对小鼠耳朵染料渗出的抑制效果比HCTP更为显著,体现出其更优越的抗过敏活性。综上所述,利用益生菌发酵获得的FHCTP具有更良好的肥大细胞稳定作用,并能够有效缓解肥大细胞介导的小鼠被动皮肤过敏反应。本研究结果有望推动食药物质抗过敏产品的研发与应用。

Abstract: In this study, the physicochemical properties of polysaccharides from Houttuynia cordata Thunb. fermented with Lactiplantibacillus plantarum HM6008 (FHCTP) were determined, and the antiallergic activity was evaluated using rat basophilic leukemia (RBL)-2H3 cells. The results showed that fermentation increased the ratio of mannose to sulfate in FHCTP. Compared with H. cordata Thunb. polysaccharides (HCTP), the particle size of FHCTP decreased by 26.67%, and its stability in aqueous solution increased. The inhibition rate of FHCTP on the degranulation of RBL-2H3 cells was significantly higher than that of HCTP, (82.79 ± 5.19)% versus (53.75 ± 1.95)%. After FHCTP intervention, the expression of fragment crystallizable epsilon receptor I (FcεRI) was significantly down-regulated, and the average fluorescence intensity decreased from 2 458.00 ± 7.50 to 1 495.00 ± 28.50. Both FHCTP and HCTP effectively inhibited the isomerization of cytoskeletal proteins and the increase of intracellular calcium ion concentration. In addition, in the mouse passive cutaneous anaphylaxis assay, FHCTP showed a more significant inhibitory effect on dye extravasation in mouse ears, indicating stronger antiallergic activity. In conclusion, FHCTP has better stabilizing effect on mast cells and effectively alleviates mast cell-mediated passive cutaneous anaphylaxis in mice. The results of this research are expected to promote the development and application of antiallergic products from edible and medicinal materials.
