KLRA1P and malaria: Klra1 expression induced by blood-stage malaria in the liver of non-vaccinated mice reveals a late maximum with a mRNA level of approximately 70 above normalization level towards the end of the crisis phase on day 11 p.i., while in vaccination-protected mice, a very early maximum expression of approximately 78 occurs at early pre-patency on day 1 p.i. before declining to a minimum of approximately 40 at early patency on day 4 p.i. (Figure 4).
