Hematology Branch, National Heart, Lung, and Blood Institute, National Institutes of Health, Bethesda, MD, USA
Lancet 364:355-64. 2004..In most cases, no obvious aetiological factor can be identified. However, clinical responses to immunosuppression strongly suggest an immune pathophysiology...

Hematol J 5:255-61. 2004..In summary, the spectrum of effects of ATG on hematopoietic progenitors is dependent upon the concentrations of ATG and may not be related to its antigenic specificity...
Oligoclonal and polyclonal CD4 and CD8 lymphocytes in aplastic anemia and paroxysmal nocturnal hemoglobinuria measured by V beta CDR3 spectratyping and flow cytometryAntonio M Risitano
Hematology Branch, National Heart, Lung and Blood Institute, National Institutes of Health, Bethesda, MD, USA
Blood 100:178-83. 2002..As V beta skewing may correlate with relative V beta size, oligoclonality in combination with numerical V beta expansion can be applied to recognition of disease-specific T-cell receptors...

Superior growth of glycophosphatidy linositol-anchored protein-deficient progenitor cells in vitro is due to the higher apoptotic rate of progenitors with normal phenotype in vivoGuibin Chen
Hematology Branch, National Heart, Lung and Blood Institute, National Institutes of Health, Bethesda, MD, USA
Exp Hematol 30:774-82. 2002..CONCLUSIONS: These results strongly suggest that clonal expansion of GPI-AP-deficient progenitor cells from PNH patients is due to their selection in the hostile marrow environment of the patient...
Frequent HPRT mutations in paroxysmal nocturnal haemoglobinuria reflect T cell clonal expansion, not genomic instabilityGuibin Chen
Haematology Branch, National Heart, Lung, and Blood Institute, National Institutes of Health, Bethesda, MD 20892-1652, USA
