As a major type of immune cells with heterogeneity and plasticity,macrophages are classically divided into inflammatory (M1) and alternative/anti-inflammatory (M2) types and play a crucial role in the progress of the inflammatory diseases.Recent studies have shown that metabolism is an important determinant of macrophage phenotype.Mitochondria,one of the most important compartments involving cell metabolism,are closely associated with the regulation of cell functions.In most types of cell,mitochondrial oxidative phosphorylation (OXPHOS) is the primary mode of cellular energy production.However,mitochondrial OXPHOS is inhibited in activated M1 macrophages,rendering them unable to be converted into M2 phenotype.Thus,mitochondrial metabolism is a crucial regulator in macrophage functions.This review summarizes the roles of mitochondria in macrophage polarization and analyzes the molecular mechanisms underlying mitochondrial metabolism and function,which may provide new approaches for the treatment of metabolic inflammatory diseases.
