Figure 1. Role of NKT cells in the control of ALA in mice.

Mice treated with α-GalCer or mice lacking CD1d (CD1d^−/−) were intrahepatically infected with virulent E. histolytica trophozoites. Seven days p.i. animals were sacrificed and sizes of liver abscesses determined. Bars represent sizes of abscess scores relative to those of wildtype control mice (WT). Results were obtained from 3 independent experiments comprising 5 to 7 animals each (statistics: Mann-Whitney U test).
