MIF and anemia (phenotype): To this end, TgAlbCre-IL10-/- mice were treated starting from day 30 p.i. (i. e. a time point when anemia difference between the groups became apparent, see Fig 3D) with 250 μg of a half-life extended anti-MIF Nb for ~3 weeks (twice per week) and infection parameters (anemia and parasitemia) were monitored.
