Fig. 3: IFN-γ stimulated wild type murine show increased loading of Irga6 onto the PVM of type III parasites.

Primary neuron cultures were treated as in Fig. 1, followed by infection with listed T. gondii strains. At 12 hpi cultures were fixed and stained with anti-Irga6 and anti-Tuj1 antibodies. The stained cultures were analyzed by confocal microscope. A Representative images of stained cultures from wild type (WT) mice infected with type III parasites. Blue = anti-Tuj1 antibodies, green = anti-Irga6 antibodies, red = mCherry expressing parasites. B Quantification of the percentage of Irga6+ parasitophorous vacuoles (PVs) in the setting of vehicle or IFN-γ pre-stimulation. C Representative images as in A except infected with III + ROP18 parasites. D As in B. E Representative images as in A except using cultures from Irgm1/3 KO mice. A, E Scale bar = 10 µm full image, 5 µm inset. F As in B. G Representative images as in C except using Irgm1/3 KO neurons. H As in B. B, D, F, H Bars- mean ± SEM, N = 100–200 PVs/experiment, 3 independent experiments. ND = not detected. Unpaired t-test with Welch’s correction. Source data are provided as a Source Data file.
