When pregnancy tames the wolf.

A state of relative immunosuppression exists in normal pregnancy. In this issue of , Hong et al. (https://doi.org/10.1084/jem.20190185) perform blood immunomonitoring in pregnancy, in both healthy women and women with lupus, and observe early and sustained transcriptional modulation of lupus-related pathways in both groups. When signatures of inflammation did not normalize in lupus, risk of pregnancy complications was increased.
