Role of β2 integrins in the prevention of apoptosis induction in chronic lymphocytic leukemia B cells

Immunologically committed lymphocytes, especially mature, leukemic B cells, proliferate then accumulate without further cell division in chronic lymphocytic leukemia patients (CLL). These mature, leukemic B cells often produce autoantibodies. Under normal circumstances, immunologically committed lymphocytes that are autoreactive are deleted by a programmed cell death mechanism. In CLL cells, these mechanisms appear to be inhibited; therefore,...
