FIGURE 1: Model of possible roles for amebic lysosomes in amebic trogocytosis and cell killing. Amebic lysosomes might be required for rapid degradation of the ingested fragments, for efficient recycling of ingested receptors and membrane, or for the rapid formation of an acidified synapse at the site of ameba-host interaction. Blue triangles vesicles indicate V-ATPases. Red ovals indicate amebic Rab7B.
