We report here the clinical features of a pregnant woman with PNH and present an immunhistochemical analysis of complement regulators, leukocyte activation markers and placental alkaline phosphatase (PALP) on syncytiotrophoblasts and inflammatory cells in her placenta. Placental tissue from normal deliveries served as controls. The patient had severe PNH with haemolysis, thrombosis episodes and signs of bone marrow failure. Placental syncytiotrophoblasts and villous cells of fetal origin in both normal placentas and the placenta from the PNH patient expressed PALP and the complement regulators CD46, CD55 and CD59. Additionally, CD11b\u2010positive leukocytes of presumed maternal origin were negative for CD15 in the PNH placenta, while they stained positive within the villous space and in normal placentas. These findings show that fetally derived cells in the PNH placenta expressed GPI\u2010linked molecules that are known to be of importance for a successful pregnancy outcome.<\/jats:p>","DOI":"10.1111\/j.1365-3083.2006.01777.x","type":"journal-article","created":{"date-parts":[[2006,6,19]],"date-time":"2006-06-19T15:46:27Z","timestamp":1150731987000},"page":"140-144","update-policy":"http:\/\/dx.doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Placental Expression of Glycophosphatidylinositol (GPI)\u2010anchored Proteins in Paroxysmal Nocturnal Haemoglobinuria"],"prefix":"10.1111","volume":"64","author":[{"given":"E.
