Two-dimensional principal component analysis (PCA) of the uninfected, trophozoite-infected and gametocyte-infected RBCs based on their lipid composition. PCA results were plotted in two-dimensional plots that reflect the behaviour of the RBCs infected with different blood-stage parasites (score plot, left graph) corresponding to the molecular lipid species (loadings plot, right graph). Ovals in the scores plot group the same samples of three independent experiments. uRBC uninfected red blood cells, Troph trophozoites, I–V gametocytes stage I to V, DAG diacylglycerol, FC free cholesterol, PC phosphatidylcholine, PE phosphatidylethanolamine, PS phosphatidylserine, SM sphingomyelin. PC1 first principal component, PC2 second principal component
