Figure 7 shows the malaria- and vaccination-response of Klrg1 expression. It is obviously the only gene of the NKC whose malaria-induced expression was identified to be responsive to vaccination on three different days p.i. during infection, namely on days 1, 4, 11 p.i. (Figure 7). In accordance, KLRG1 is known to sustain activation, proliferation, and expansion of NK cells in the liver [64,65]. This evidence concerns the gene KLRG1 and infection.
