Abstract

The tumor microenvironment predominantly polarizes tumor-associated macrophages (TAMs) toward an M2-like phenotype, thereby inhibiting antitumor immune responses. This process is substantially affected by metabolic reprogramming; however, reeducating TAMs to enhance their antitumor capabilities through metabolic remodeling remains a challenge. Here, we show that tumor-derived microparticles loaded with succinate (SMPs) can remodel the metabolic state of TAMs. SMPs promote classical M1-like polar...
