Pharmacological inhibitors of anaplastic lymphoma kinase (ALK) induce immunogenic cell death through on-target effects

Immunogenic cell death (ICD) is clinically relevant because cytotoxicants that kill malignant cells via ICD elicit anticancer immune responses that prolong the effects of chemotherapies beyond treatment discontinuation. ICD is characterized by a series of stereotyped changes that increase the immunogenicity of dying cells: exposure of calreticulin on the cell surface, release of ATP and high mobility group box 1 protein, as well as a type I interferon response. Here, we examined the possibility that inhibition of an oncogenic kinase, anaplastic lymphoma kinase (ALK), might trigger ICD in anaplastic large cell lymphoma (ALCL) in which ALK is activated due to a chromosomal translocation. Multiple lines of evidence plead in favor of specific ICD-inducing effects of crizotinib and ceritinib in ALK-dependent ALCL: (i) they induce ICD stigmata at pharmacologically relevant, low concentrations; (ii) can be mimicked in their ICD-inducing effects by ALK knockdown; (iii) lose their effects in th.....
