Towards Understanding the Molecular Mechanisms of Immunogenic Cell Death.

The discovery of immunogenic cell death (ICD) by small molecules (e. g., chemotherapeutic drugs) intrigued medicinal chemists and led them to exploit anticancer agents with such a trait because ICD agents provoke anticancer immune responses in addition to their cytotoxicity. However, the unclear molecular mechanism of ICD hampers further achievements in drug development. Fortunately, increasing efforts have been made in this area in recent years by using either chemical or biological approaches. Here, we review the current achievements towards understanding the mechanisms of small molecule-induced ICD effects. Based on the established role of the unfolded protein response (UPR) in ICD, we classify the mechanisms of different inducers by their dependency on UPR. Key proteins and pathways with important implications are discussed in depth. We also give our perspectives on the research strategies for future investigation in this field. © 2022 Wiley-VCH GmbH.
