How can the multifunctional factor Sonic Hedgehog (SHH) elicit specific responses from its target cells? A study now pinpoints proteoglycans as crucial anchors and modulators of SHH signaling, ...

Basement membrane (BM) proteoglycans are more than charged filtering agents. These complex macromolecules can direct cell responses by a wide range of sophisticated mechanisms. BM proteoglycans are ...

LA JOLLA, CA—Scientists at Scripps Research have developed a set of methods for the closer study of one of the least-accessible, least-understood players in biology: protein-sugar conjugates called ...

Proteoglycans—molecules consisting of a core protein with multiple sugar chains—are so complex that researchers usually study the protein and sugar components separately, which makes it difficult to ...

In a recent study published in IScience, a team of researchers from the United States examined the impact of heparan-sulfate-modified proteoglycans (HSPGs) on Alzheimer's disease-associated pathways ...
