Immune cells known as natural killer (NK) cells are linked with pregnancy problems including pre-eclampsia and recurrent miscarriage. Scientists are illuminating the role that pregnancy-related NK cells play in moderating the biochemical interactions at the boundary between maternal tissues and the developing fetus. Their findings reveal that uterine NK cells are 'armed' with specific receptors, enabling interaction with other molecules to ensure that the placenta develops normally and the pregnancy is successful.
