PfEMP1 PfEMP1

Live cell imaging showing intermediate compartments and timing of export of PfEMP1B-GFP. PfEMP1B-GFP transfectants were co-labeled with BODIPY-ceramide and samples were collected from a tightly synchronized culture (2 hours). (A) BODIPY-ceramide-labeled features (white arrows) are present in the RBC cytoplasm by 6 h post-invasion, while PfEMP1B-GFP is still located in a "necklace of beads" pattern at the parasite surface (aqua arrows). (C) At 10-12 h postinvasion PfEMP1B-GFP is observed in compartments in the RBC cytoplasm (yellow arrows). (E) By ~24 h post-invasion the PfEMP1B-GFP-labeled structures have become immobilized. Scale bars = 3 μm.
