摘要
The NAD(P)H oxidase in the syncytiotrophoblast of the term human placenta, which had previously been identified only by cytochemical methods, has been solubilized and a number of its biochemical properties have been defined. It is a protein composed of a 58 kDa and a 33 kDa subunit, with properties that clearly distinguish it from the respirator burst oxidase of transient neutrophils and macrophages. The enzyme activity is constitutive in the trophoblast and is a source of reactive oxygen species (ROS) at the fetal-maternal interface. (C) 2001 Harcourt Publishers Ltd.
