Glycans are reservoirs of information that can be decoded at cell-cell interfaces.
We use state-of-the-art techniques from immunology and synthetic chemistry to engineer the glycocalyx and develop next-generation cell-based therapies.
How do glycans impact signalling at an immunological synapse?
Our interdisciplinary team of scientists at The University of Toronto work together to tackle challenging problems at frontier of glycoimmunology, chemical biology, and immunopharmacology
We create libraries of synthetic glycans using a combination of synthetic organic and chemoenzymatic strategies.
Synthetic glycans are then introduced to immune cell in culture. These cells are assessed for viability and display of the engineered glycocalyx is verified using a variety of analytical strategies.
Glycoengineered cells are ‘co-cultured’ with other immune cells to assess the impact of the altered glycocalyx on antigen specific immune activation or suppression.
‘Hit’ cells with desirable activity are adoptively transferred into a host diseased animal and the impact of these cells on pathology is monitored. For example, glycoengineered cells with immunosuppressive character could be designed to attenuate progression of inflammatory arthritis.
A successful therapy produces a healthy animal and provides the framework for the development of next-generation treatments for human diseases.
