Abstract

The use of Saccharomyces cerevisiae mnn mutants has facilitated the study of the epitopes recognized by antisera against several antigenic factors of the genus Candida (Candida Check; Iatron Laboratories, Tokyo, Japan). We have taken advantage of the very well characterized structure of the mannans of the different mnn mutants to compare their reactivities with the factor antisera used in the identification of different species of the genus Candida. The results of this study provide evidence that one of the antigenic determinants recognized by factor 1 antisera is the O-linked mannose chains of the cell wall mannoproteins, while that recognized by factor 9 antiserum is the alpha 1-6-linked mannose backbone of the outer chain of the N-linked oligosaccharide.

摘要

酿酒酵母mnn突变体的使用促进了针对念珠菌属几种抗原因子的抗血清所识别表位的研究(念珠菌检测;日本东京医创株式会社)。我们利用不同mnn突变体甘露聚糖特征明确的结构,比较它们与用于鉴定念珠菌属不同菌种的因子抗血清的反应性。这项研究结果表明,因子1抗血清识别的抗原决定簇之一是细胞壁甘露糖蛋白的O-连接甘露糖链,而因子9抗血清识别的是N-连接寡糖外链的α1-6连接甘露糖主链。
