Expression of functional toll-like receptors by B-chronic lymphocytic leukemia cells

Haematologica. 2007 Sep;92(9):1279-81. doi: 10.3324/haematol.10975.

Abstract

This study reports that B-chronic lymphocytic leukemia (B-CLL) cells display the same pattern of toll-like receptors (TLRs) proteins expression as normal B-cells, yet with overexpression of TLR9. Furthermore, TLR7 and TLR9 appear to be functional and liable to respond to specific ligands, respectively imidazoquinolines and CpG-ODN thus potentially opening new therapeutic approaches.
