GP1BB and malaria: In the liver of both vaccinated and non-vaccinated mice, the expression course of Gp6 in response to blood-stage malaria resembled that of Gp1ba, Gp1bb, Gp5, and Gp9, in particular with respect to a significantly (p-value < 0.01) higher expression in vaccinated mice on day 4 p.i. than in unvaccinated mice (Figure 5).
