When chronic lymphocytic leukemia (cll) was last reviewed in the Journal, it was considered a homogeneous disease of immature, immune-incompetent, minimally self-renewing B cells, which accumulate relentlessly because of a faulty apoptotic mechanism. In the past decade, these views have been transformed by a wealth of new information about the leukemic cells. CLL is now viewed as two related entities, both originating from antigen-stimulated mature B lymphocytes, which either avoid death through the intercession of external signals or die by apoptosis, only to be replenished by proliferating precursor cells.

Abstract
When chronic lymphocytic leukemia (cll) was last reviewed in the Journal, it was considered a homogeneous disease of immature, immune-incompetent, minimally self-renewing B cells, which accumulate relentlessly because of a faulty apoptotic mechanism. In the past decade, these views have been transformed by a wealth of new information about the leukemic cells. CLL is now viewed as two related entities, both originating from antigen-stimulated mature B lymphocytes, which either avoid death through the intercession of external signals or die by apoptosis, only to be replenished by proliferating precursor cells.
