Fig. 7. Kelch13 is essential for parasite virulence in mice.
a, b IFA and western blot detection of complemented HA-TgKelch13 in the AID-Kelch13 line by growth in ±IAA for 24 h. Actin served as a control. Scale bar = 5 μm. c Plaque formation by the AID-K13 and complementation lines grown in ±IAA for 7 days. Scale bar = 0.5 cm. d Survival of mice infected with TIR1, AP2αc-AID, EPS15-AID, AID-K13, tKD and the complementation line (AID-K13/TgK13) in the absence (with vehicle) and presence of auxin. Mice survival was monitored for 20 days post-infection. One representative result was shown from three independent experiments, and 100 parasites were used per mouse for infection. Survival data were analyzed by the Gehan-Breslow-Wilcoxon test, comparing to the TIR1 +IAA. ***p < 0.0001, and p values are provided; not significant for AID-K13/TgK13 +IAA vs. TIR +IAA.
