A physiologic roll for cell surface GlycoRNAs.

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. [ABSTRACT FROM AUTHOR]
