摘要: 目的 评估从红树林土壤中分离的真菌PH1008胞外多糖在小鼠阴道白假丝酵母菌感染模型中的抗感染效应,为抗假丝酵母菌感染开发新的治疗药物提供思路。方法 用真菌PH1008胞外多糖干预小鼠阴道白假丝酵母菌感染模型,提取阴道组织进行转录组基因表达水平测定以评估胞外多糖的抗感染效应。结果 增强了肝细胞生长因子、补体1受体等基因的表达水平,且这一上调现象与多个信号传导途径密切相关。结论 真菌PH1008胞外多糖局部干预小鼠阴道后可诱导机体产生抗白假丝酵母菌感染效应,相关机制有待于进一步研究。

Abstract: Objective To evaluate the anti-infective effect of polysaccharide isolated from fungus PH1008 in vaginal Candida albicans infection model of mouse,and to provide a new and potential pathway to the development of anti-candida drugs. Methods Determination of gene expression level of transcriptome in mice vagina after yeast infection mouse model was treated by exopolysaccharide of fungus PH1008. Results The expression of hepatocyte growth factor and complement 1 receptor was increased, and the up-regulation was related to varied signal transduction pathways. Conclusions The anti-infection effect of Candida albicans can be induced by vaginal mucosal immunization with exopolysaccharide of fungus PH1008, and the relevant mechanism needs further research.
