Cancer immunotherapies have shown remarkable benefits, but many tumors remain unresponsive to existing treatments. The mechanisms cancer cells use to evade immune responses during treatment remain largely unknown. Altered cell surface glycosylation, the process of attaching sugars to cell surface biomolecules, is a hallmark of many human cancers. The interaction between cell surface glycoproteins on immune cells with cancer cells represents a major axis of immune evasion and plays a vital role in how cancer cells suppress immune responses during cancer treatment. Dr. Roberts’ [Connie and Bob Lurie Fellow] research aims to molecularly define cell surface glycosylation and understand the role of glycosylation in driving cancer immunosuppression. This knowledge will be leveraged to illuminate the underlying mechanisms of tumor immune evasion and enable next-generation classes of cancer immunotherapies. Dr. Roberts received his PhD from University of Wisconsin–Madison, Madison and his BS from University of California, San Diego.
