TgTSA1 increases resistance to NO without changing NO production. (A) Infected macrophages (Mφ) were activated in the presence of 1 mM aminoguanidine. The number of parasites/vacuole was determined by immunofluorescence 33 h after infection. Data from a representative experiment are displayed as the average percentage of total vacuoles ± standard error determined from triplicate counts. (B) Macrophages (Mφ) were induced with LPS and IFN-γ 3 hours after infection. Twenty-four hours postinfection, media from the infected wells were tested for the presence of nitrite. Samples were tested in triplicate. Data from a representative experiment are displayed as the average level of nitrite (μM) detected ± standard error. MOI, multiplicity of infection.
