CALR and neoplasm: Previous studies indicated that the induction of ferroptosis promotes the release of calreticulin, an immunogenic cell death‐related protein, leading to enhanced engulfment of dead or dying cells by dendritic cells, more antigenic substances delivered to immune cells, and stronger antitumor immunogenicity.[12b,c] To determine whether similar immunogenic effects also occurred in our model, we employed histochemical staining and flow cytometry to detect the infiltration of immune cells in tumor tissues.
