Macrophage Mitochondrial Metabolism

Macrophage mitochondrial metabolism refers to the dynamic and highly regulated processes by which mitochondria in macrophages generate energy, regulate redox balance, and influence immune responses. Mitochondria serve as metabolic hubs that integrate signals from the environment to coordinate cellular functions such as activation, polarization, and inflammatory responses. Upon activation, macrophages undergo metabolic shifts; M1 (pro-inflammatory) macrophages increase glycolysis and reduce OXPHOS, while M2 (anti-inflammatory) macrophages rely on fatty acid oxidation (FAO) and robust mitochondrial respiration. Shifts in mitochondrial metabolism directly impact cytokine production, inflammasome assembly, and phagocytic capacity. Macrophage function can be fine-tuned by targeting specific aspects of their mitochondrial metabolism.
