Figure 1: STAT6−/− mice efficiently control Toxocara canis infection. Course of i.p. T. canis infection in STAT6−/− (solid circles) and STAT6+/+ (open circles) mice following infection with 500 L2. Data are expressed as the mean SE of 4–6 mice per group. comparing STAT6−/− versus STAT6+/+ at the same time point. Similar results were observed in two independent experiments.
