The initiation and progression of bladder cancer (BC), is dependent on its tumor microenvironment (TME). On the other hand, cancer cells shape and train TME to support their development, respond to treatment and migration in an organism. Immune cells exert key roles in the BC microenvironment and have complex interactions with BC cells. These complicated interplays result in metabolic competition in the TME leading to nutrient deprivation, acidosis, hypoxia and metabolite accumulation, which impair immune cell function. Recent studies have demonstrated that immune cells functions are closely correlated with their metabolism. Immunometabolism describes the functional metabolic alterations that take place within immune cells and the role of these cells in directing metabolism and immune response in tissues or diseases such as cancer. Some molecules and their metabolites in the TME including glucose, fatty acids and amino acids can regulate the phenotype, function and metabolism of immune cells. Hence, here we describe some recent advances in immunometabolism and relate them to BC progression. A profound understanding of the metabolic reprogramming of BC cells and immune cells in the TME will offer novel opportunities for targeted therapies in future.
