TATi1-Ku80 and cKd-TgATG8 parasites were produced in their host cells with or without ATc. After 24?h, the number of Betamipron parasites per vacuole was determined. Values are the mean the standard error of the mean of three impartial experiments, where 200 vacuoles were counted for each condition.

Protein lysates from parasites expressing Tomato-TgATG8, GFP-TgATG8, or mutated versions of these proteins where glycine 124 was replaced with an alanine (G124A, abrogates the ability to be conjugated to lipids) were separated by SDS-PAGE in the presence of 6?M urea and analyzed by Western blotting. The faster-migrating form corresponds to the Betamipron PE-conjugated, and thus membrane-bound, form of the protein, as (i) it is absent from your G124A cell lines and (ii) conjugation is usually induced by starvation in HBSS medium like native TgATG8, although in that case, membrane recruitment seems less efficient for Tomato-TgATG8.

Shown is an immunofluorescence analysis of HFF monolayers infected for 24?h in the presence of ATc by parental TATi1-Ku80 and mutant cKd-TgATG8 parasites, stained for peripheral apicoplast protein TgATRX1, analyzed together with stromal protein TgCPN60 (A) and DAPI (B).

Shown is usually a vacuole made up of TgATG8-depleted tachyzoites produced for 48?h with ATc with an apparently intact apicoplast in the residual body (a magnified view is presented on the right).

Organelles were analyzed by IFA in intracellular tachyzoites of the parental cell collection and the TgATG8 conditional knockdown after 3?days of incubation with ATc. (A) Mitochondria were labeled with anti-TgHSP60 antibody (top), and the proportion of parasites displaying a fragmented mitochondrion was quantified (bottom). (B) Micronemes were labeled with anti-TgAMA1 antibody. (C) The IMC was labeled with anti-TgIMC1 antibody. (D) Dense-granule secretion was assessed with an anti-TgGRA3 antibody, and rhoptries were labeled with an anti-TgRON4 antibody. Level bars, 5?m.

An immunofluorescence analysis of cKd-TgATG8 intracellular tachyzoites after 24?h days of ATc incubation is usually shown. The apicoplast and centrosomes were labeled with anti-TgATRX1 and anti-centrin1 antibodies, respectively; the Golgi apparatus was labeled by transient Betamipron expression of the RFP-fused GRASP protein.
