has remarkable plasticity and heterogeneity,which upon different stimulus can undergo correspondingРfunctional and phenotypic changes,and plays a key role in tissue repair after injury.Currently,lines of evidence have shownРthat macrophage metabolism affects the tissue repair process by regulating macrophage phenotype and function.This reviewР describes the relationships between macrophage metabolism and tissue repair,with an emphasis on the characteristics of M1Р and M2 macrophages in glycolysis,the Krebs cycle,fatty acid oxidation,and arginine metabolism.This review alsoР summarizes the research progress on tissue repair regulation by targeting the key substrates and kinases in the metabolicР process of macrophages.Р Key words:macrophage metabolism;macrophage polarization;tissue repair
