PTVI pathway is preferentially used by avirulent Toxoplasma strains. (A) Comparison of F-actin induction by adherent type III (CTG), type II (ME49), and type I (GT-1) Toxoplasma tachyzoites at resting RAW264.7 cell surface 8 min following synchronized infection by temperature switch. (B) Baf A1 sensitivity of PVM formation by intracellular CTG, ME49, and GT-1 parasites 40 min after infection of resting RAW264.7 cells. Immunostaining and data analysis are same as in Fig. 2C. Data are presented as mean ± SD in triplicates.
