Researchers Identified GlycoRNA Species in Extracellular Vesicles
Scientists found that glycoRNAs reside on cell surfaces and travel between cells via extracellular vesicles.
Updated on Sept. 28, 2026 in Life Sciences
Researchers have identified distinct glycoRNA species within extracellular vesicles, revealing that these molecules carry diverse sequences specific to vesicle types. The study demonstrates that these vesicles deliver glycoRNAs into recipient cells, suggesting a new mechanism for inter-cellular communication.
Why it matters
These findings uncover a previously unknown pathway for molecular exchange between cells. Understanding how glycoRNAs function may provide new insights into how cells regulate their behavior and environment.
The team utilized metabolic tagging with bioorthogonal handles to successfully enrich and sequence these glycoRNAs. A proximity-based imaging strategy was also employed to track the precise movement of these molecules from the cell surface to recipient cells.
The details
The research highlights that glycoRNA repertoires in large extracellular vesicles vary significantly based on cell type and passage. Because these vesicles successfully deliver their cargo, scientists expect these molecules to serve as critical biomarkers of cell state and regulators of vesicle tropism.
