title: Mechanistic and therapeutic overview of glycosaminoglycans: the unsung heroes of biomolecular signaling.
abstract: Immune regulation is a complex biological signaling pathway in which several classes of biomolecules and small molecules play a complacent role to mediate this process. Glycoimmunology is a rapidly evolving research area that deals with the structure, binding interactions and immunological functions of glycans. Great deal of information regarding proteins and nucleic acids in molecular recognition events have been established owing to their well-established structural features and straight forward replication, transcription and translation principles. However considering the complexities of template free synthesis and structural heterogeneity, role of carbohydrates in immune regulation are still unsung to a large extent. In the current review, we illuminate the canonical structural features, emerging and significant pathophysiological functions of glycosaminoglycans (GAGs), the negatively charged linear carbohydrate molecules that are primarily present on all types of cell surfaces and extra cellular matrix. A snap shot of their association with protein counterparts of diversified protein families has been updated exclusively to provide mechanistic insights into their cellular signaling functions. Eventually, this review throws light on the recent biomedical/biotechnological advances of GAG based biomarkers, nutraceuticals, therapeutics, and nanocomposites for inflammatory, immune disorders and their invaluable contribution in tissue engineering.
