Targeted gene disruption of PfPAP changes the filterability of the infected RBCs but not the expression or localization of KAHRP, REX1, and PfEMP-3. B). Immunofluorescence using anti-KAHRP, REX1, and PfEMP-3 antibodies on 3D7 and 3D7_PAP KO show no difference in the location of these proteins. C). Electron microscopy of 3D7_PAP-KO showing electron dense structures at the surface of the infected erythrocyte indicative of the presence of knobs. Bars are 5 mm.da Silva FL, Dixon MW, Stack CM, Teuscher F, Taran E, Jones MK, Lovas E, Tilley L, Brown CL, Trenholme KR, Dalton JP, Gardiner DL, Skinner-Adams TS.

PfEH1 and PfEH2 interact with the erythrocyte cytoskeleton. IFA of paraformaldehyde/ glutaraldehyde-fixed, trophozoite/early schizont-stage parasites expressing PfEH1-GFP (A) or PfEH2-GFP (B) under control of the respective endogenous promoter. The GFP-expressing parasites were costained with anti-RESA (red). The nuclei were stained with DAPI (blue). Bars = 5 mm. DIC, differential interference contrast. In asexual parasites, anti-GFP antibody detected PfEH1 and PfEH2 at the periphery of the infected erythrocyte and within the parasite. The fluorescence at the periphery colocalized with ring-exported surface antigen (RESA), an exported protein that interacts with host spectrin at the RBC cytoskeleton.Spillman NJ, Dalmia VK, Goldberg DE.

Four a/b-hydrolases are exported into the erythrocyte compartment. Immunofluorescence assay (IFA) of trophozoite/early schizont-stage parasites overexpressing GFP-tagged a/b-hydrolases. Parasites were fixed with paraformaldehyde/glutaraldehyde and stained with anti-GFP (green). The nuclei were stained with 4’,6’-iamidino-2-phenylindole (DAPI) (blue). (A) PfEH1-GFP, (B) PfEH2-GFP, (C) PfXL1-GFP, and (D) PfXL2-GFP. Expression was under control of the constitutive HSP86 promoter. The images are representative of at least three independent experiments. Bars=5 mm. DIC, differential interference contrast. For the two a/b-hydrolase familyA members, fluorescence was observed at the periphery of the infected erythrocyte and within the parasite (A and B). In contrast, for the two family B members, fluorescence was diffuse throughout the cytosol of the infected RBC (C and D).Spillman NJ, Dalmia VK, Goldberg DE.
