Real-time RT-PCR analyses of nuclear receptor expression in the liver. Levels of RXR, FXR, CAR, PXR, and VDR mRNA were analysed in hepatic RNA of vaccinated (circles) and non-vaccinated (triangles) mice on the indicated days after P. chabaudi infection. Signals were normalized to 18S rRNA and relative expression is given as fold increase compared to non-vaccinated mice on day 0 p.i. All values are mean and half S.E.M. **, p < 0.01 vs. non-vaccinated control on the same day p.i. *, p < 0.05 vs. non-vaccinated control on the same day p.i.
