Special Issue Information

Dear Colleagues,

Heparan sulfate (HS), an abundant glycosaminoglycan on cell surfaces and the extracellular matrix, exhibits critical regulatory roles for numerous proteins involved in vital biological processes. HS exerts its biological functions by interacting with hundreds of HS-binding proteins, including growth factors, chemokines, cytokines, coagulation factors, enzymes, matrix proteins, etc. The diverse interactions between HS and proteins modulate activities ranging from developmental signaling to homeostatic mechanisms such as coagulation, angiogenesis, bone remodeling, and host defense. Given the importance of HS–protein interactions, targeting these molecular interfaces has recently emerged as a focal point of research with potential therapeutic implications. Current investigative strategies involve the development of specific antibodies and HS oligosaccharide mimetics designed to modulate HS–protein binding, thereby offering opportunities for innovative therapeutic approaches. Additionally, certain natural sulfated carbohydrates, such as those derived from seaweeds and marine organisms that possess a negative charge, may function similarly to heparan sulfate oligosaccharides in this context. This Special Issue aims to highlight the latest advances in our understanding of HS biology, the molecular basis of HS–protein interactions, and the translational potential of targeting these interactions for various pathological conditions.

Surface plasmon resonance (SPR) is a powerful tool for analyzing biomolecular interactions and is widely used in basic biomedical research and drug discovery. Heparan sulfate (HS) is a linear complex polysaccharide and a key component of the extracellular matrix and cell surfaces. HS plays a pivotal role in maintaining cellular functions and tissue homeostasis by interacting with numerous proteins, making it essential for normal physiological processes and disease states. Deciphering the interactome of HS unlocks the mechanisms underlying its biological functions and the potential for novel HS-related therapeutics. This review presents an overview of the recent advances in the application of SPR technology to HS interactome research. We discuss methodological developments, emerging trends, and key findings that illustrate how SPR is expanding our knowledge of HS-mediated molecular interactions. Additionally, we highlight the potential of SPR-based approaches in identifying novel therapeutic targets and developing HS-mimetic drugs, thereby opening new avenues for intervention in HS-related diseases.
