Placenta-specific molecular basis that is responsible for the pathophysiology of preeclampsia (PE) remains to be fully understood. Adenosine, an endogenous nucleoside, is a signaling molecule that is induced under pathological conditions such as hypoxia and is involved in various diseases. Recent evidence on humans and animal models has demonstrated that enhanced placental adenosine signaling contributes to the development of PE. This review is to summarize current progress and discuss the significance of adenosine signaling in the pathophysiology of PE and future perspectives of therapeutic possibilities targeting adenosine signaling.
