Glycopolymers against pathogen infection

Pathogens including viruses, bacteria, fungi, and parasites continue to shape our lives in profound ways every day. As we have learned to live in parallel with pathogens, we have gained a better understanding of the rules of engagement for how they bind, adhere, and invade host cells. One such mechanism involves the exploitation of host cell surface glycans for attachment/adhesion, one of the first steps of infection. This knowledge has led to the development of glycan-based diagnostics and therapeutics for the treatment and prevention of infection. One class of compounds that has become increasingly important are the glycopolymers. Glycopolymers are macromolecules composed of a synthetic scaffold presenting carbohydrates as side chain motifs. Glycopolymers are particularly attractive because their properties can be tuned by careful choice of the scaffold, carbohydrate/glycan, and overall presentation. In this review, we highlight studies over the past ten years that have examined the role of glycopolymers in pathogen adhesion and host cell infection, biofilm formation and removal, and drug delivery with the aim of examining the direct effects of these macromolecules on pathogen engagement. In addition, we also examine the role of glycopolymers as diagnostics for the detection and monitoring of pathogens.

Automated summary

Pathogens, including viruses, bacteria, fungi, and parasites, have a significant impact on our lives. Understanding their mechanisms of adhesion and invasion of host cells has led to the development of glycan-based diagnostics and therapeutics. Glycopolymers, macromolecules with carbohydrates as side chain motifs, have become increasingly important due to their tunable properties. In this review, we discuss the role of glycopolymers in pathogen adhesion and infection, biofilm formation and removal, and drug delivery, as well as their use as diagnostics for pathogen detection and monitoring.
