Dendritic cells (DCs) are professional antigen-presenting cells that serve as messengers between innate and adaptive immunity. Due to their unique roles, DCs are under active investigations as the target for antigen delivery in vaccination against human immunodeficiency virus (HIV), cancer and autoimmune diseases. However, there’s yet no perfect strategy for a cost-effective, high-selective and time-saving detection and isolation of DCs from a complex cell population. Adhesion molecules such as DC-specific intracellular adhesion molecule-3 grabbing non-integrin (DC- SIGN) on the surface of DCs play a critical role in establishing contact between the activated DCs and the naïve T cells through interactions with intercellular adhesion molecule-3 on T cells. DC-SIGN is a member of the C-type lectin receptors and can recognize antigens bearing mannose-rich or fucosylated glycans, as well as Lewis X (LeX). Here, we present the fabrication of magnetic nanoparticles coated with multivalent LeX glycans using the Cu (I)-catalyzed azide-alkyne cycloaddition. The resulting nanoparticles are selective and biocompatible, serving as a highly efficient tool for DC capture detection and enrichment.
