IL-21 regulates miRNA expression in B-chronic lymphocytic leukemia

ABSTRACT: B-cell chronic lymphocytic leukemia (CLL) is a common type of leukemia, characterized by the progressive accumulation of CD5+ “mature” monoclonal B lymphocytes in peripheral blood, bone marrow and lymphoid tissues. Although circulating CLL cells are non-dividing cells, prone to spontaneous apoptosis, their progressive accumulation is the result of a dynamic balance between cell death and proliferation and a high turn-over rate has been related to a poor prognosis. Indeed, CLL cells are protected from apoptosis and proliferate in specific niches within the lymphoid tissues and the bone marrow. By gene-expression profiling we found out that IL-21 modulates the expression of several genes including cytokine and chemokine genes and genes involved in cell survival and apoptosis in CD40-activat
