WebPregnancy-associated plasma protein A (PAPP-A) is a protein produced first by the growing placenta. During a normal pregnancy, levels of this protein increase in the pregnant woman’s blood until delivery. Should I worry about low PAPP-A? PAPP-A is considered to be low when it is less than or equal to 0.41 during pregnancy. WebAll pregnant women were measured for nuchal translucency (NT) at gestational age of 11-13 + 6 weeks. Time-resolved immunofluorescence analysis was used to detect the serum pregnancy-related protein (PAPP-A) and free β-human chorionic gonadotropin (fβ-hCG) levels of pregnant women.

WebIntroduction. Pregnancy-associated plasma protein-A (PAPP-A) is a 200 kDa zinc-binding metalloproteinase of the metzincin superfamily. PAPP-A circulates as a 500 kDa disulfide-bound complex with eosinophil major basic protein in pregnancy and as a 400 kDa homodimer outside pregnancy. 1 It is mainly produced by placental trophoblasts and is … WebPregnancy-associated plasma protein-A (PAPP-A) is a key component of an interactive cellular mechanism promoting pulmonary fibrosis.
