Pretreatment with IFNγ promotes astrocytes infection by <i>T. cruzi</i>.

<p>(A) Experimental scheme showing that primary astrocyte cell cultures were pretreated with IFNγ (10 ng/mL) for 2 hours and subsequently infected using MOI 1:1 or 10:1 and analyzed 4 hours post-infection (p.i.). (B) and (C) show the frequencies of <i>T. cruzi</i>-infected cells and the number of parasites per cells, when initial infection MOI was 1:1 or 10:1, respectively. Data are presented as mean ± SEM of triplicates. *, <i>p</i> < 0.05 and **, <i>p</i> < 0.01 comparing not-treated (NT) with IFNγ pretreated astrocytes in each studied MOI.
