Fig. 7. Accumulation of C-PAK enhances phagocytosis of human RBCs by E. histolytica. The histogram shows the erythrophagocytosis rates of E. histolytica strains. Wild-type (WT) (white) and transfectants C-PAK (black) or MyoIB⁺ (grey) were used. To quantify engulfed RBCs the concentration of haemoglobin inside parasites was measured as described previously (Voigt et al., 1999). Bars indicate standard deviations of the means after three independent experiments.
