() is an emerging multidrug-resistant fungal pathogen that represents a significant public health challenge as it can spread rapidly and result in high mortality rates. The mannans on the cell surface are potent immunogens and attractive targets for developing a glycoconjugate vaccine. We synthesized the oligosaccharides resembling cell surface mannans of and printed them onto microarray slides that were used to screen plasma from mice infected with . IgM antibodies in mouse plasma recognize the β-1,2 linkage present in surface mannans. Disaccharide 19 emerged from glycan array screening as a lead for developing a vaccine against , as the majority of patient plasma samples showed antibodies against this glycan. The synthetic oligosaccharides can be used for the early detection of infections.
()是一种新兴的多重耐药真菌病原体,它能迅速传播并导致高死亡率,对公共卫生构成重大挑战。细胞表面的甘露聚糖是有效的免疫原,也是开发糖缀合物疫苗的有吸引力的靶点。我们合成了类似于()细胞表面甘露聚糖的寡糖,并将其打印到微阵列载玻片上,用于筛选感染()的小鼠的血浆。小鼠血浆中的IgM抗体识别()表面甘露聚糖中存在的β-1,2连接。二糖19从聚糖阵列筛选中脱颖而出,成为开发抗()疫苗的先导,因为大多数患者血浆样本显示出针对这种聚糖的抗体。合成的寡糖可用于()感染的早期检测。
