AI Insight
Scientists have developed a new method to deliver sugars (glycans) directly into cells, addressing a longstanding challenge in glycobiology research. The innovation overcomes the primary obstacle that hydrophilic glycans cannot easily cross cell membranes, which previously required modifying them with water-repelling chemical groups and using potentially harmful solvents. This technique enables more direct and safer delivery of glycans for cellular studies.
Why it matters
This method could significantly advance research into cell signaling, disease mechanisms, and pathogen interactions, as glycans play crucial roles in these processes. It may accelerate studies of diseases like cancer, where changes in glycosylation patterns are implicated, by providing researchers with a safer and more efficient tool to introduce glycans into cells for experimental purposes.
Understand the Science
Sugars, or glycans, play a crucial role in biology—from cell signaling and recognition to interactions with pathogens. Changes in glycosylation are also associated with diseases including cancer. But studying glycans poses a major challenge: because many glycans are highly water-soluble, or hydrophilic, they cannot easily cross the cell membrane and must be modified with a hydrophobic moiety—a water-repelling chemical group—and prepared and delivered using potentially harmful solvents.
