Synthetic, biodegradable nanoparticles (NPs) encapsulating at least one of a signal 1 protein, a signal 2 protein, and/or a signal 3 protein are disclosed, which, when transfected into one or more a cancer cells, reprogram the one or more cancer cells into “tumor-derived APCs” in vivo to activate T-cells and natural killer (NK) cells for systemic tumor rejection. The NPs can be used for treating cancers, in particular metastatic cancers.
