Role of Tumor Microenvironment in Prostate Cancer Immunometabolism

The tumor microenvironment (TME) plays a pivotal role in shaping immunometabolism in prostate cancer, influencing disease progression and therapeutic response. This review examines the dynamic interactions between tumor cells and immune cells within the prostate cancer TME, focusing on how metabolic reprogramming of both tumor and immune cells drives immunosuppression. Key immune players, including T-cells, macrophages, and myeloid-derived suppressor cells, undergo metabolic adaptations influenced by hypoxia, nutrient deprivation, and signaling from tumor cells. Additionally, we discuss the metabolic pathways involved, such as glycolysis and oxidative phosphorylation, and how these processes are exploited by cancer cells to evade immune surveillance. Furthermore, this review highlights potential therapeutic strategies targeting immunometabolism, including metabolic inhibitors and their combination with immunotherapies. A deeper understanding of the complex role of immunometabolism in prostate cancer will not only provide insights into the tumor's immune evasion mechanisms but also facilitate the development of novel treatment approaches that enhance the efficacy of current therapies.
