Abstract

Fut2-LacZ-null mice, which are a model of the human ABO and Lewis nonsecretor group, display increased susceptibility to experimental yeast vaginitis, indicating a role for alpha(1,2)fucosylated cervical glycans in mucosal defense. However, the lack of significant effect of competitive inhibition by exogenous neoglycoproteins in this study emphasizes the complexity of Candida-epithelial cell adhesion events.

摘要

Fut2-LacZ基因敲除小鼠是人类ABO和Lewis非分泌型血型的模型,对实验性酵母性阴道炎的易感性增加,表明α(1,2)岩藻糖基化宫颈聚糖在黏膜防御中发挥作用。然而,本研究中外源新糖蛋白竞争性抑制作用缺乏显著效果,这突出了念珠菌与上皮细胞黏附事件的复杂性。
