摘要

Metabolic reprogramming is one of the fundamental characteristics of thyroid cancer (TC), which meets its energy and biosynthetic demands through mitochondrial dysfunction, glycolysis activation, lipid metabolism imbalance, and glutamine dependency, thereby promoting metastasis and reshaping the immune microenvironment. Exosomes, as extracellular vesicles, play a crucial role in TC by delivering bioactive molecules such as proteins, lipids, and nucleic acids. In the tumor microenvironment (TME) of TC, exosomes secreted by both tumor and non-tumor cells interact with each other, driving metabolic reprogramming and forming a bidirectional regulatory network. This significantly alters the biological characteristics of TC cells, including proliferation, invasion, metastasis, angiogenesis, and the acquisition of drug resistance and immune tolerance, ultimately influencing the process of immune escape in TC. This review systematically summarizes how exosomes in the TME of TC promote tumor progression through metabolic reprogramming, providing new diagnostic and therapeutic strategies for patients with locally advanced, radioiodine-refractory TC.
