DAI-1 Receptor Expression in Placenta in Earlyand Late-Onset Preeclampsia

DAI-1 receptor (DNA-dependent activator of IFN-regulatory factors; DLM-1/ZBP-1) is an innate immunity cytoplasmic receptor of the DNA-recognition receptor class of antiviral immunity. DAI-1 expression reflects the severity of the inflammatory response that plays the key role in the pathogenesis of pregnancy complications. We studied DAI-1 receptor expression in the placental villi in early- and late-onset preeclampsia. In case of early-onset preeclampsia DAI-1 staining intensity was lower (p=0.01), and in case of late preeclampsia — significantly higher (p<0.005) than in the reference groups at the corresponding gestational age. There was revealed a correlation between the decrease in DAI-1 receptor expression and the severity of disease progression.
