Immunogenic Cell Death Amplified by Co-localized Adjuvant Delivery for Cancer Immunotherapy.

ABSTRACT: Despite their potential, conventional whole-cell cancer vaccines prepared by freeze-thawing or irradiation have shown limited therapeutic efficacy in clinical trials. Recent studies have indicated that cancer cells treated with certain chemotherapeutics, such as mitoxantrone, can undergo immunogenic cell death (ICD) and initiate antitumor immune responses. However, it remains unclear how to exploit ICD for cancer immunotherapy. Here, we present a new material-based strategy for converting immunogenically dying tumor cells into a powerful platform for cancer vaccination and demonstrate their therapeutic potential in murine models of melanoma and colon carcinoma. We have generated immunogenically dying tumor cells surface-modified with adjuvant-loaded nanoparticles. Dying tumor cells laden w
