Abstract

A library of mannose- and fucose-based glycomimetics was synthesized and screened in a microarray format against a set of C-type lectin receptors (CLRs) that included DC-SIGN, DC-SIGNR, langerin, and dectin-2. Glycomimetic ligands able to interact with dectin-2 were identified for the first time. Comparative analysis of binding profiles allowed their selectivity against other CLRs to be probed.

摘要

合成了一系列基于甘露糖和岩藻糖的聚糖模拟物库，并以微阵列的形式对一组 C 型凝集素受体（CLRs）进行了筛选，其中包括 DC-SIGN、DC-SIGNR、 langerin 和 dectin-2。首次鉴定出能够与 dectin-2 相互作用的聚糖模拟配体。对结合谱的比较分析允许探测它们对其他 CLRs 的选择性。
