Figure 3. ROP18 blocks Irgb6 loading.
(A) Immunofluorescence localization of Irgb6 on the parasite-containing vacuole in infected Gr1+ monocytes examined at 30 min post infection. Irgb6 localized with rabbit polyclonal Ab (Alexa Fluor 488, green); GRA5 localized with mAb Tg 17-113(Alexa Fluor 594, red); and nuclei stained with DAPI (blue). Scale = 5 μm.
(B) Quantification of Irgb6 localization to the PV in Gr1+ monocytes. Mean ± SEM, n=3 experiments (*P < 0.005, Student's t test).
(C) CryoimmunoEM localizing Irgb6 to the parasite-containing vacuole membrane (arrowheads) in macrophages. Scale = 0.5 μm.
