Aberrant regulation of complement by the erythrocytes of hereditary erythroblastic multinuclearity with a positive acidified serum lysis test (HEMPAS).
Susceptibility to hemolysis in acidified serum is a pathognomonic feature of hereditary erythroblastic multinuclearity with a positive acidified serum lysis test (HEMPAS, congenital dyserythropoietic anemia type II). The purpose of the studies reported herein was to determine if aberrant regulation of complement contributes to the susceptibility of HEMPAS erythrocytes to acidified serum lysis. ...
متن کاملDiagnostic power of laboratory tests for hereditary spherocytosis: a comparison study in 150 patients grouped according to molecular and clinical characteristics.
BACKGROUND The laboratory diagnosis of hereditary spherocytosis commonly relies on NaCl-based or glycerol-based red cell osmotic fragility tests; more recently, an assay directly targeting the hereditary spherocytosis molecular defect (eosin-5'-maleimide-binding test) has been proposed. None of the available tests identifies all cases of hereditary spherocytosis. DESIGN AND METHODS We compare...
متن کاملMechanisms of immune lysis of the red cells in hereditary erythroblastic multinuclearity with a positive acidified serum test and paroxysmal nocturnal hemoglobinuria.
The red cells of patients with hereditary erythroblastic multinuclearity with a positive acidified serum test (HEMPAS), a form of congenital dyserythropoietic anemia, and the cells of patients with paroxysmal nocturnal hemoglobinuria (PNH) are lysed more readily than normal cells by certain antibodies, notably cold agglutinins (anti-I) and complement. With some but not other examples of anti-I,...

متن کاملEffects of glucosamine on lysis, glycerol formation, and sporulation in Myxococcus xanthus.
Glucosamine (GlcN), which has previously been shown to rescue fruiting body formation, lysis, and sporulation in a developmental mutant (G. Janssen and M. Dworkin, Dev. Biol. 112:194-202, 1985), induced lysis in vegetative and developing wild-type cells and inhibited fruiting body formation. It also resulted in a transient, intracellular increase in the concentration of glycerol, a known sporul...
