Molecular basis of mature T-cell leukemia.


T-cell chronic lymphocytic/prolymphocytic leukemia (T-CLL/T-PLL) is a lymphoproliferative disease derived from immunocompetent post-thymic T cells. Activation (initiation of expression) of the TCL1 locus at chromosome 14q32.1 appears to be the causal event in the pathogenesis of these mature T-cell leukemias. This activation occurs as a result of… (More)
