Peroxisome proliferator-activated receptors in macrophage biology: friend or foe?

Author information

Lipid Metabolism Unit, Massachusetts General Hospital, Harvard Medical School, Boston, Massachusetts, USA.


Peroxisome proliferator-activated receptor (PPAR)-gamma is a nuclear hormone receptor, with a well-established role in adipogenesis and glucose metabolism. Over the past 3 years several laboratories have reported that this protein can influence macrophage responses to a variety of inflammatory stimuli. The effect of PPAR-gamma activation on macrophage lipid uptake, cholesterol efflux, and cytokine production have all recently been examined in several in-vitro culture systems. In addition, PPAR-gamma ligands have been shown to influence atherosclerotic lesion formation in murine models of that disease. This review attempts to summarize and critically evaluate that work and its implications for the use of PPAR-gamma activators in understanding and treating the pathogenetic processes that contribute to atherosclerotic plaque formation.
