Impact of Glycochemistry on Targeted Drug Delivery
Glycochemistry plays a pivotal role in the development of targeted drug delivery systems, and Bertozzi’s research has been at the forefront of this intersection. Carbohydrates are integral to many biological processes, including cell signaling, immunity, and pathogen recognition. By harnessing the unique properties of glycans, Bertozzi’s lab has been able to devise strategies that exploit these naturally occurring molecules for better therapeutic targeting.
The lab’s focus on glycan recognition has enabled the creation of therapeutics that can selectively bind to specific cell types based on their carbohydrate signatures. This specificity is particularly beneficial in oncology, where tumors often exhibit altered glycan expressions compared to normal tissues. By delivering drugs that utilize these glycan interactions, Bertozzi’s work has the potential to increase the precision of cancer therapies and reduce off-target effects, improving patient outcomes.
Moreover, the impact of glycochemistry extends to the design of vaccines and immunotherapies. Bertozzi’s insights into glycan structures have informed the engineering of vaccine components that can elicit robust immune responses. By strategically incorporating glycans into vaccine designs, her lab has contributed to the development of more effective immunization strategies, illustrating the broad applicability of glycochemistry in enhancing drug delivery systems across various therapeutic areas.
