Figure 6. Endocytosis of LDL in Giardia trophozoites.
Wild-type Giardia trophozoites challenged with unlabelled LDL (+LDL panels) show a reduction of BODIPY-LDL uptake compared with unchallenged trophozoites (−LDL). Addition of chylomicrons specifically inhibits the endocytosis of BODIPY-LDL because no fluorescence is observed at any time point in these cells (+Chylomicrons). Bar, 10 μm.
