Purpose Of Review: The biology of hairy-cell leukaemia is reviewed, focussing first on the hairy cell itself and then on its interactions with the microenvironment.
Recent Findings: Hairy cells are highly activated clonal B cells related to memory cells, normally resident in the marginal zone of the spleen. Their activation results from multiple stimuli arising from the microenvironment, autocrine cytokines and the still unknown transforming oncogenic event(s) responsible for the disease.
Background: The aims of the present study were to ascertain the activation status of Akt in the primary cells of chronic lymphocytic leukemia and to investigate the effects of specific Akt inhibition on chronic lymphocytic leukemia-cell survival.
Design And Methods: Anti-phospho-Akt (Ser473 or Thr308) antibodies and western blotting were used to establish the activation status of Akt. The effects of two different, specific small-molecule inhibitors (A-443654 or Akti-1/2) or small interfering RNA on cell survival and downstream targets of Akt were assessed.
