Fig. 7. T. cruzi vacuole maturation involves an early PI
3-kinase-dependent step. CHO cells were pulsed with (A,B) T. cruzi or
(C) IgG-coated latex beads for 10 minutes, washed extensively and incubated in
the absence or presence of 40 nM wortmannin for a total of 10, 20, 30, 45 and
60 minutes. (D) Kinetics of lamp-1 association with the T. cruzi
vacuole in untreated CHO cells (control), cells pre-treated with 40 nM
wortmannin for 30 minutes (wortmannin-pre) or in wortmannin pretreated cells
to which drug was added after 10 minutes of infection (wortmannin pre+post).
