A Physiologic Roll for Cell Surface GlycoRNAs

Abstract Glycosylated RNA molecules that can be bound by lectins have been demonstrated on the surfaces of leukocytes, but their physiologic function(s) was not known. A recent study (PMID 38262409) demonstrates that at least 1 function is to promote capture and rolling of neutrophils in the vasculature. Of interest, the neutrophil glycosylated RNA molecules bind to P-selectin but not E-selectin.
