FYB1 and infection: However, the frequency of NK cells that reached the different maturation stages (CD27−CD11b− (DN) → CD27+CD11b− → CD27+ CD11b+ (DP) → CD11b+CD27−) was the same by day 5 post-infection (Supplementary Figure 3) and as such impaired NK cell maturation was largely excluded as a reason for the pronounced ADAP-dependent differences in NK cell abundance in the spleen of Lm infected mice.
