Sweet and sour: the impact of sugars on disease.

The clinical relevance of glycobiology has become the focus of considerable research, as the role of glycosylation in the development, regulation and progression of disease is, slowly but surely, being unveiled. Recent strides in the design and refinement of analytical techniques-sugar profiling, glyco-arrays and functional studies-have helped us gain a better understanding of the complexity and richness of diversity that bestow sugars with an unsurpassed, biospecific coding capacity. Cracking this 'sugar code', and unravelling the structural frameworks and recognition strategies of sugar-based interactions in biological systems that relate to both health and disease, holds tremendous promise for deciphering disease mechanisms. It will also provide a cutting edge potential for the development of novel diagnostic and therapeutic interventions.
