Immune Cell Homing Biomaterials for Cancer Immunotherapy

Abstract
Immunotherapy has shown the promise to cure cancer by boosting systemic anticancer immune responses, especially with the success of checkpoint blockades and chimeric antigen receptor (CAR)-T cell therapies in the past decade. However, there remains tremendous room for the development of new-generation immunotherapies that can generate more robust and persistent cytotoxic T lymphocyte responses. One of my research interests is to understand how immune cells can be manipulated or engineered using chemistry, material, and chemical biology approaches, in order to develop effective therapies for cancers and other diseases. In this talk, I will talk about three research projects centered around immune cell-homing materials. In the first work, I will introduce how dendritic cells (DCs) can be recruited to a macroporous hydrogel and metabolically labeled with unique chemical tags in situ, for subsequent tracking and targeting of DCs in vivo. The chemically tagged DCs enable targeted conjugation of immunomodulatory agents via efficient click chemistry, for the development of potent cancer vaccines and cytokine therapies. In the second work, I will talk about how DC-homing macroporous gels can be utilized to develop antigen-free in situ cancer vaccines for treating poorly-immunogenic solid tumors. This approach enables one to bypass the costly, lengthy, and lowly successful antigen identification steps for developing therapeutic cancer vaccines. Lastly, I will introduce our recent work in developing a T cell-responsive macroporous hydrogel that enables activation and expansion of T cells in situ, which holds promise for improving current T cell therapies.
