Specific killing of CCR9 high-expressing acute T lymphocytic leukemia cells by CCL25 fused with PE38 toxin
2011
Abstract We have previously demonstrated that CCR9 plays a pivotal role in drug resistance and invasion in human acute T-lymphocytic leukemia (T-ALL). In this study, we investigated whether the MOLT4 cells, which naturally express CCR9 at high levels, can be successfully killed by the specific ligand, CCL25 fused to Pseudomonas exotoxin 38 (PE38) toxin. Our results demonstrated that CCL25-PE38 was able to specifically kill MOLT4 cells via apoptosis induction, and suppress the growth of CCR9 + tumors. This work shows that CCR9 high-expressing human T-ALL cells can be successfully killed by delivering PE38 toxin fused to the ligand CCL25.
