We investigated CD19+CD34+ and CD19+CD34- B cells from cord blood (CB) and typical patients with B cell lineage acute and chronic lymphocytic leukemia (B-ALL and B-CLL) in terms of expression and functions of CXCR5/CXCL13 and CCR7/CCL19. CXCR5 and CCR7 were selectively frequent expressed on B-ALL, B-CLL and CB CD19+CD34+ B cells, but not on CD19+CD34- B cells. Instead of induction of impressive chemotactic responsiveness, CXCL13 and CCL19 together induced significant resistance to TNF-alpha-mediated apoptosis in B-ALL and B-CLL but not CB CD19+CD34+ B cells. B-ALL and B-CLL CD19+CD34+ B cells expressed elevated level of Paternally Expressed Gene 10 (PEG10), and CXCL13 and CCL19 together significantly up-regulated PEG10 expression in the cells. We found that CXCL13 and CCL19 together by means of activation of CXCR5 and CCR7 up-regulated PEG10 expression and function, subsequent stabilized caspase-3 and caspase-8 in B-ALL and B-CLL CD19+CD34+ B cells, and rescued the cells from TNF-alpha-mediated apoptosis. We suggested that normal lymphocytes, especially naive B and T cells, utilized CXCR5/CXCL13 and CCR7/CCL19 for migration, homing, maturation, and cell homeostasis as well as secondary lymphoid tissues organogenesis. Meanwhile certain malignant cells took advantages of CXCR5/CXCL13 and CCR7/CCL19 for infiltration, resistance to apoptosis, and inappropriate proliferation.
