MLKL and neoplasm: To gain more insight into the immune pathways responsible for the MLKL-mRNA-mediated antitumor responses, we probed the influx of DCs in the tumor bed and in the tumor draining lymph node by flow cytometry on days 1 and 2, respectively, after two intratumor treatments with mRNA encoding MLKL (Fig. 8a, b; Supplementary Fig. 6).
