Magnetic Thermal Ablation Combined with Temporally Coordinated CpG Immunotherapy Promotes cDC1‐Dependent Immune Priming in Hepatocellular Carcinoma

open access: yesAdvanced Science, EarlyView.
Novel PLA@Fe3O4 magnetic microspheres were developed for transarterial magnetic hyperthermia ablation (MTA) of hepatocellular carcinoma. While destroying local tumors and inducing immunogenic cell death (ICD), MTA combined with early CpG adjuvant administration significantly promotes cDC1‐dependent immune priming. This synergistic mechanism effectively
