Metabolic Interdependency of Th2 cell-mediated type 2 immunity and the Tumor Microenvironment (TME): The TME is characterized by a high energy demand, glycolysis, and lipid metabolism. This reduces 02 and glucose availability within the TME, while free FA, other lipids and lactate is found to be elevated. These conditions affect Th2 cells and their effector functions (e.g. cytokine production of IL-4, IL-5, and IL-13) and, secondary, eosinophil mobilization and activation. 02, Oxygen; IL, Interleukin; Ox., Oxidation; FA, Fatty acid(s).
