Abstract
Glycans play an important role in many neuronal processes, such as neurotransmitter release and reuptake, cell–cell communication and adhesion, modulation of ion channel activity, and immune function. Carbohydrate click chemistry is a powerful technique for studying glycan function and dynamics in vitro, in vivo, and ex vivo. Here, we use commercially available synthetic tetraacetylated azido sugars, copper and copper-free click chemistry to metabolically label and analyze primary rat cortical neurons. In addition, we use high resolution confocal and STED microscopy to image and analyze different forms of glycosylation in ultrahigh resolution. We observe different patterns of GlcNAz, GalNAz, and ManNAz distribution at different stages of neuronal development. We also observe highly sialylated structures on the neuronal plasma membrane, which warrant further investigation.
