PPM1D and infection: Our group found that wild-type p53-induced phosphatase 1 (Wip1) plays a critical role in neutrophil maturation, and genetic or pharmacological inhibition of Wip1 could increase the infiltration of neutrophils into the primary infection sites and enhance their antimicrobial function (Liu et al., 2013; Shen et al., 2017b; Shen et al., 2017c).
