Paroxysmal nocturnal hemoglobinuria (PNH)may be considered the paradigm a disease caused by complement dysregulation specifically on erythro-cytes; in fact, PNH is a clonal, non-malignant, hematological disorder characterized by the expansion ofhematopoietic stem cells and progeny mature blood cells which are deficient in some surface proteins,including the two complement regulators CD55 and CD59.
