Deciphering novel roles of glycans in human disease

The Petrey Lab investigates how a type of complex sugars found on cell surfaces and in the extracellular matrix called glycosaminoglycans (GAGs) function to shape immune responses and contribute to human health & disease.

By combining biochemical, translational, and cellular approaches, our team aims to uncover how these molecules influence inflammation, infection, and tissue repair.

Our team’s work is helping to reveal new pathways and potential therapeutic targets in conditions ranging from chronic inflammatory disorders to critical injury and cancer.
