What is it about?
Neutrophils are critical first-line responders to infection forming a potent line of innate immune defense. Neutrophils are armed with highly glycosylated microbicidal proteins essential for combatting invading pathogens, yet little is known about how, when, and where the microbicidal proteins are glycosylated during neutrophil maturation. Using systems glycobiology to investigate blood neutrophils and their progenitors, we find that profound glycoproteome remodeling accompanies the early neutrophil maturation phase when microbicidal glycoproteins are produced. The study provides spatiotemporal insights into the glycophenotype of key neutrophil compartments and the peculiar glycosylation that decorates microbicidal proteins.

Why is it important?
The study forms a resource to guide future explorations targeting the biological roles and dysregulation of glycosylation in neutrophil-related disorders.
