These results demonstrate the utility of a modular NP design for systematic screening of signal 2/3 delivery to melanoma in vivo and highlight the benefit of in-depth profiling via spatial proteomics to evaluate local antitumor immune responses. The results provide insight into the mechanisms underpinning this therapeutic reprogramming strategy, emphasizing the relationship between signal 2/3 NPs and their ability to drive signal 1 for productive antitumor responses in vivo.
