Glycoconjugates – glycans linked with proteins, lipids, or other molecules – are a crucial component of many therapeutics, including protein-based drugs and vaccines targeting microbial pathogens. The innate immune system detects proteins and pathogens via their non-host surface glycans, leading to the activation of an immune response and a clearance of these molecules from the body. In this theme we will advance approaches in this area to develop new therapeutic proteins and vaccines for a host of conditions.
