From: A new era in melanoma immunotherapy: focus on DCs metabolic reprogramming

Different metabolic pathways in melanoma-associated DCs. DCs exhibit the ability to assume diverse tumorigenic and immunogenic phenotypes as a reaction to the tumor microenvironment and external stimuli. In each case, the cells engage specific metabolic pathways to maximize their functional efficacy.
