Peroxisome proliferator-activated receptor gamma-retinoid X receptor (PPARgamma-RXR) agonists had minimal effects on the surface levels of CD36, intercellular cell adhesion molecule-1, or platelet-endothelial cell adhesion molecule-1 and had no effect on the cytoadherence of infected erythrocytes to either human umbilical vein endothelial cells or human microvascular endothelial cells or on malaria-induced interleukin-6 secretion from these cells. PPARgamma-RXR agonists do not significantly modify malaria-infected erythrocyte-endothelial cell interactions in vitro.
